Seat assembly

The invention relates to a seating unit. More specifically, the invention relates to a seating unit for an aircraft cabin.

In most aircraft the first class cabin is equipped with large spaced with wide spaced from each other to provide passengers with seating space and comfort during their travels. Currently, virtually every first class cabin is fitted with large double seats with a pitch (longitudinal distance between seats) of at least 1500 mm.

This design suffers from several drawbacks seats. Seats can not be arranged horizontally, and it makes uncomfortable sleeping passengers. Also there is no privacy between the two chairs. It can be very confusing passengers, especially during their sleep. Passengers said that the feeling is akin to being in bed with a stranger. Of course, it would be possible to design the chairs for the horizontal position. However, this creates another problem relating to the way the seats recline. Where the chair leans back, he leans back into the space of the passenger sitting behind. It is psychologically unpleasant for passengers who feel that their living space is violated. It also makes it difficult for passengers to lean back behind the chair to leave their seats without disturbing other passengers. This is particularly difficult for the occupants of the chair by the window, which will disturb both passengers in the back seats recline front and a passenger in the aisle seat next to the passenger, who is leaving his seat. One way of overcoming this problem would be, of course, the increase in pitch between the seats, for example, up to 2 meters. This is undesirable because it is obvious that it reduces the capacity to seat inside the cabin just for the sake of one, relatively minor advantage.

Moreover, the design of existing first class seating is not suitable to provide individual space for each passenger. Passengers prefer to keep personal belongings within reach and presently this is only possible if bags, pillows, newspapers etc. located on the floor of the cabin. Consequently, the interior becomes very untidy during a flight, especially if it's a long night flight.

The purpose of this invention - to overcome or at least reduce the above problems.

According to one aspect of the invention provides a seating for an aircraft cabin, comprising a stationary housing, a chair with a backrest disposed in the stationary housing and the portion for seating, the trolley associated with a part for sitting chairs, wherein the trolley is adapted to bring it into motion to move parts for seat between a retracted position and an extended position, with some seating and backrest are made with the possibility of interaction, so that when you move part of the seating between retracted and extended positions is provided by the movement of the back between the substantially vertical and reclined position, finding back substantially within the housing, wherein the residence time in the backrest reclined position and finding portion for seating in the extended position and the back portion of the seat forms a substantially flat surface.

Preferably, the back was connected at one end thereof to the seating portion.

Advantageously, the assembly further comprises guiding means for guiding the backrest between substantially upright and reclined position.

Desirably, the assembly further comprises guiding means for guiding the seating portion to change its orientation by moving the seating portion between a retracted and extended positions.

It is possible that the node further comprises a footrest movable between a retracted position and a supporting position.

Advantageously, the footrest has been configured to move between a retracted and supporting positions independently of the driving the trolley to move.

Desirably, the back, seat portion and footrest form a substantially flat sleeping surface when the back is in a reclined position, the seating portion is in the extended position, and the support leg is in the supporting position.

It is possible that the node further comprises a surface extension that is separate from the chair, and to interact with the surface of an elongated support leg, when finding the leg support in the support position, for lengthening surface for sleeping.

Preferably, the elongation of the surface was carried out to attach to the back of another seat.

Advantageously, the surface of the extension containing the auxiliary chair.

It is desirable that the surface extension was rotatable to prevent any object between the extension surface and the leg support when moving the footrest between retracted and supporting positions.

It is possible that the auxiliary seat comprising a fixed portion and a rotatable portion adapted to be rotatable to prevent any object between the extension surface and the leg support when moving the footrest between retracted and supporting positions.

Preferably, the guide means and the back portion for the seat are attached to the stationary housing.

Advantageously, the fixed housing comprises a back casing, and guide means back was arranged to move the seatback forward in relation to the back of the stationary housing.

Desirably, there was a further motor for driving the trolley to move.

It is possible that there was a further motor for moving the footrest.

Preferably, the node further comprises a user-controlled means for controlling the motor.

Desirably, the assembly further comprises user-controlled means for controlling the motor.

It is possible that the node further comprising a household means adjacent to the chair and structurally separated from it to accommodate the use of domestic resources of individual occupants of the chair.

Preferably, the flow of domestic funds had storage space for personal items of the passenger.

Advantageously, the unit comprises means domestic television type monitor.

It is advisable to block domestic funds contained a table, a chair confronts.

It is possible that the node further comprising a household means, adjacent to the seat and structurally separated from it by means for placing individual household use for occupants of the chair, wherein the block household tools arranged on one side surface of the seat and extending between the seat surface and elongation.

According to another aspect of the invention provides a seating for an aircraft cabin, comprising a stationary housing with a main seat, which comprises

recliner operable to tilt so that it remains substantially within the housing,

seating portion adapted to move with the deviation back to move back between the substantially vertical position and a substantially horizontal position,

a footrest configured to move between a retracted position and the reference position,

a motor for moving the seat portion for a forward extended position in which the backrest is in a substantially horizontal position,

wherein a portion for seating, backrest and footrest are adapted to cooperate to form a substantially flat surface when finding backrest substantially horizontally tilted position and finding the footrest at the reference position.

Preferably, the assembly further comprises an auxiliary seat disposed so as to face the primary seat, the auxiliary seat comprises a part for sitting, situated to engage the footrest main seat to form part of a substantially flat surface, when finding the backrest a main seat reclined, substantially horizontal position.

Until now, the seat placed in the cabin uniformly in a configuration in which rows of seats are arranged perpendicular to the axis of the aircraft. Typically, each row of seats is located at a fixed distance from standing in front of a number, so that each passenger has the same space. Same distance also allows the installation of the back of the chair to support the table and provides space for storage, and in some cases even put the TV screen, and other auxiliary facilities and services for the occupants of the back seat. Using the rear side of seat support means for supporting the chair back is undesirable compromise which results in the actions of one passenger interfere with other passengers during a flight.

From an examination of the description that follows, it will be apparent that the configuration of staggered (zigzag) enables each passenger greater degree of privacy. This arrangement allows you to place partitions between adjacent seating units to determine the extent of space per passenger. Staggered configuration can also provide more places in the same space without any appreciable loss of interior space for a single passenger.

The above and further features of the invention are detailed in the appended claims and together with its advantages will become apparent from a consideration of the following detailed description taken only as an example of embodiment given with reference to the accompanying drawings.

Figure 1 shows an assembly for seating or seating unit 1 installation comprising primary, leans back seat 2 and the secondary, fixed seat 3. Both seats 2, 3, unit 1 are provided for use only first-class passengers. Of course, how to use a seat 2, 3, depending on the passenger, but provided that he himself will use the primary seat 2 during the trip and that he will use the secondary seat 3 for other passengers, whom he invited to join him at the time of travel .

A second unit 4 comprising its own primary seat 5 and secondary seat 6 may be placed next to the first unit 1. In such a situation, the first node 1 and the second unit 4 are separated by a dividing wall 7 which provides privacy between the two units 1, 4. To this end, the dividing wall 7 comprises a partition wall 8 between the primary seats 2, 5 of the two units and the partition 9 between the secondary seats 3, 6. A further partition-wall 10 extends behind the two secondary seats 3, 6 to provide further privacy.

The two units 1, 4 shown in Figure 1, constructed for placement in the center of the cabin and offered a pair of people traveling together. For this reason, the two walls 8, 9 are modest in size and do not interfere with the passengers sitting in the two nodes 1, 4, talk to each other. For convenience, the retractable baffle (not shown) may be provided in any partitions 8, 9, or both partitions 8, 9 for pulling up the dividing wall to completely separate from each other the two units 1, 4, when the passengers are not traveling together.

The space between the primary seat 2 and the secondary seat 3 of each unit is large, and in fact sufficient for the table, which is placed between the two seats 2, 3. The dividing wall 7 includes a table storing portion 11. As shown in Figure 2, a table 12 placed in the storing portion 11 may be placed between the primary seat 2 and the secondary seat 3 during a flight optional passenger.

The horizontal or upper region 13 between the secondary seat 2 and the baffle 10 can be used by the passenger to store his briefcase hand, newspapers or other personal belongings optional passenger. A television screen (not shown) may be conveniently is hung above the surface 13 or within the separating wall 7.

An even greater degree of privacy may be achieved by arranging nodes seating ledges or overlap. One way in which seating units may be staggered is shown in Figure 3. With this arrangement, a plurality of seating units 15 is provided along the edge of interior 16. Each of the assemblies 15 comprises a primary seat 17 and secondary seat 18. When a passenger sits in the primary seat 17 of any of the units 15 he faces outward from the aircraft. For convenience, this overlapping configuration will be referred to herein as the outward-facing device. It should be noted that two pairs of units 1, 4 and 1 ', 4' are provided along the center line 19 of the cabin. These units 1, 4 and 1 ', 4' are similar to the nodes shown in Figures 1 and 2, but it should be noted that between nodes 1 'and 4' has a larger area than that between nodes 1 and 4. The amount of space between the nodes can be selected depending on the space available inside the cabin and in anticipation of passengers preferences.

Another way that you can install components for seating benches, shown in Figure 4. A plurality of seating units provided again by the edge number 16, each assembly 21 comprises a primary seat 22 and secondary seat 23. When a passenger sits in the primary seat 22 of any of the units 21 he will face inwardly directed cockpit. For the sake of convenience this overlapping configuration will be referred to herein as facing inside the device. Like the apparatus shown in Figure 3, pairs of units 1, 4 and 1 ', 4' are also provided along the center line 19 of the cabin.

Both ledges set placement make efficient use of cabin space to the extent that the interior 16 can accommodate the same number of passengers that can be placed using a known first double device with a large two meter spacing. The choice of whether to use an inward-facing device or facing outwards, is arbitrary, since there is no significant advantage in the cost of one device over another. Preliminary research has shown that passengers are likely to prefer facing outwards device, because it provides a greater sense of privacy than an inward-facing device. When handling the device outside the passengers have to turn the whole body to see other passengers in the cabin, while the inside of the device when handling the passengers are already looking inward toward the other passengers.

Design components for seats not depend on whether the node is designed for sitting for the center position, or to the regional situation in the outward-facing device. 5 and 6 each show views in perspective of two of the seating units designed for use in the device 3 facing outwardly. It should be noted that while the general construction of each unit 15 is substantially the same as the structure described above, node 1, to the effect that the primary seat 17 and secondary seat 18 are separated and facing each other, many details this design are different.

The wall 24 extends between one side of the primary 17 and secondary 18 seats. Flat top part (such as "counter") 25 extends from the wall 24 to the inner wall of the cab (not shown) and provides a surface for the passenger space of his personal belongings at his desire. One storage space may of course also be provided in the wall 24, if necessary. The baffle 26 extends from the back of the primary seat 17 across the flat top portion 25. The partition 26 defines a boundary between consecutive nodes 15, providing privacy from other passengers. As shown in Figure 6, the table 27 may be provided in the flat upper portion 25 behind the access slots 28.

Each of Figures 7 and 8 shows an isometric view of assembly 21 suitable for use inwardly facing configuration of Figure 4. The basic construction unit 21 to seat, is substantially the same as the above-described assemblies 1 and 15, for the fact that the assembly 21 comprises a separated space primary 22 and secondary 23 seats facing each other, but again several details of the design differ from Some details of the construction of the above units 1 and 15.

The wall 29 extends along one side of the primary seat 22 and secondary seat 23 and the flat upper part ("counter") 30 extends from the top wall 31 to the wall of the cabin. The slit 32 provided in the flat upper portion 30 comprises a table 33 which can be mounted sliding or rotational manner so that it can be pulled by the passenger and placed between the primary 22 and secondary 23 seats as shown in Figure 8. Successive nodes 21 seats are separated by a partition 34 for solitude. Additional structure comprising a wall 35 and surface 36 is provided between the partition 34 and the primary seat 22 for use by the passenger. Cabinets or other storage space (not shown) may be provided in the wall 29 and / or in the wall 35.

As shown, the wall 29 does not pass along the primary seat 22. Instead, part of it missing, allowing the passenger to use the space under the flat top portion 30 for storing personal baggage. The primary seat 22 (and in fact the primary seat 2 or 17) can be rotationally fixed to the unit 21 for seating in order to allow the seat to rotate in a forward-facing position (if this is necessary to meet the rules relating to take-off and landing). In this case, no portion of the wall 29 would enable the rotation of seat 22 to a position in which the passenger's feet are placed under the flat upper part 30.

The primary seat 2, 17 and 22 can be folded back. 9, 10 and 11 show in schematic form how one of the primary seats, say primary seat 2, can recline continuously between a vertical position (9) and a substantially horizontal position (Figure 11). The primary seat 2 comprises a fixed gap 41 that encloses backrest 42, seat portion 43 and a footrest 44. During flight, seat 2 can be reclined to a position (shown in Figure 10) in which a passenger (not shown) It lies in the chair, and his back supported by the backrest 42, and his feet are supported footrest 44.

If a passenger wants to sleep, the part of the seating 43 and the footrest 44 may be made from a niche 41 until footrest 44 touches the designated seating portion 45 of the secondary seat 3. In this position, the backrest 42 is substantially horizontally niche 41. Thus, the back 42 of the seating 43 and the footrest 44 with the primary seat intended to seat portion 45 of the secondary seat form a substantially horizontal surface on which passengers can sleep. Back reclining mechanism of the primary seat is represented schematically cross lines 46, 47 in the drawings, and as the design of such a mechanism by itself is well known, it does not require further explanation here. Leaning back mechanism can be operated manually or automatically using electric motors, etc. (not shown).

It should be noted that the primary seat is arranged so that the backrest 42 always remains within the recess 41 and thus do not interfere with the location of the other passengers behind.

12 is an isometric view of an outwardly facing seating unit 15 with a primary seat fully reclined so that his back 42 of the seating 43 and the footrest 44 form a horizontal surface for sleeping. This figure also shows a niche site for another 48 seats. In the back of the niches of the door 49 and 50 provide access to the space 51 of the cabinet or wardrobe, and the lower door 52 provides access to 53 additional space for storage.

13 likewise shows an inwardly directed unit 21, in which the backrest 42, intended to seat part 43 and the footrest 44 of the primary seat 22 have been completely pulled back to form, together with a dedicated seating portion 45 of the secondary seat 23 is substantially a flat, horizontal sleeping surface.

In Fig.14-17 shows the primary seat 2 within a fixed structure or housing 41 which houses the backrest 42, intended to seat part 43 and a footrest 44.

Figure 14 shows the chair 22 in a retracted position in which the backrest is substantially fully upright. It includes a seat recline mechanism comprising a runner (guide polzushka) 50 back to back 42 which is fixed at 51 support. Recline mechanism further comprises a runner 52 seats, which is connected to a part intended to seat 43 through the guide member 53 at a point 54 support. Part 43 is attached to the seat in the center of rotation 55 to one end of the backrest 42 and supported by the trolley 56 having wheels 57 that roll over the floor 58 of the cab. The floor 58 may be provided with a track in order to avoid excessive wear of the floor and facilitate smooth movement of the chair. It is desirable that runners and tracks are provided on both sides of the seat for balanced support for different parts of the chairs.

Armchair driven by electric motors (not shown), controlled by the control panel (not shown). When a passenger selects "recline backwards" on the control panel a motor causes the seating portion 43 to move forward by the rotation of the screw shaft 59 from the recess 41 to an extended position in which the backrest is in a reclined position, as shown in Figure 15. Forward movement of the seating 43 causes the back 42 is guided along the path defined by the runners 50 back. Form polozov 50 and 52 is selected in relation to the height of the trolley 56 to the orientation direction of the seating portion 43 so that it remains comfortably inclined to the horizontal while the steepness of the backrest 42 is reduced.

While the seating portion continues to move from the inclined position shown in Figure 15, in the extended position shown in Figure 16, a second motor (not shown) is activated independently of the trolley for driving the screw 60 and thereby causes the support 44 Foot move substantially from steep or vertical position shown in Figures 14 and 15 in a horizontal or reclined position shown in Figure 16. Absorber 61 may be provided at the rear side of the recess 41 for supporting the free end of the backrest 42 when the seat moves towards the horizontal position of the surface 16 and stops there.

To avoid the possibility that the passenger's feet are stuck between the support 44 for the legs and the secondary seat 3 during the movement of the support 44 for the legs from a vertical position to the horizontal, the secondary seat 3 may comprise a fixed rear seat portion 62 and a front portion of the seat 63 rotationally coupled to the rear portion 62, as shown in Figure 17. In the event that a passenger places his feet, or virtually any other object between the support legs 44 and the secondary seat 3, the front portion 63 will pivot upwardly from the path of the subject. If the passenger does not want to use a secondary seat 3, the front portion 63 may be rotated to a position above the rear portion 62 to provide more usable space on the floor for a passenger in his unit for the seat.

The uniform flight the main axis is tilted to the horizontal plane. Normally, the plane flies at an inclination of 3 °, ie, his nose pointed slightly upward. If node seating has been designed to tilt back to form a substantially horizontal surface for sleeping in a position horizontal to the plane of the wing of the aircraft, then a passenger would have to lie in a position where his head is lower than his feet when the aircraft flying at its normal 3 ° inclination. This situation is undesirable, at least because passengers find it uncomfortable. To avoid problems passengers arising from this situation, recline mechanism is designed to define a flat surface for sleep, which is slightly inclined, say 3 °, so that relative to the plane of the wing of the aircraft the passenger lies in a position in which its head It is higher than his feet. As a result, a uniform normal flight passengers head will lie in the same horizontal projection as its feet. Conveniently, a room for sleeping surface at a slight incline enables easier design handholds etc. in the recess to provide additional clearance for the shoulder of the passenger in his supine position.

18 shows an alternative secondary seat arrangement, a so-called double product. The secondary seat comprises a fixed part intended to seat 64, the back of the seat 65 rotatably connected to the connection 66 with the fixed first part 64 and the front part of the seat 67 rotatably attached to the rear of the 65 seats in the compound 68. The secondary seat can be moved between the fully extended position in which the front and rear seats is in the position represented links 65 and 67 partially extended position in which the front part is rotated around the joint 68 to the stop at verhezadney part as represented links 65 and 67 ', and a folded position, in wherein the back portion is rotated around the joint 66 for placing the front and rear portions in the positions represented by the links 65 '' and 67 ''.

Figure 19 shows the assembly 70 for seating containing Recliners 71 and node 72 auxiliary table or personal services. The second node 73 seats placed next to the unit 70 for the seat and recline chair containing 74 has its own domestic services in the node 72 personal services. Although not shown, the two nodes 70, 73 may be separated from each other by the separating wall to provide privacy between the two nodes. The two nodes 70, 73 shown in Figure 19, designed to be placed in the center compartment and discount two passengers traveling together. Node 72 personal services includes for each node 70, 73 table 75, the monitor 76 such as a television and a wardrobe and comfortable 77 defines flat surfaces for smaller items such as tea cups, etc. The cabinet 77 may be used by the passenger to store personal belongings, such as a bag with accessories for washing, headphones, etc., and can be secured storage space for magazines, newspapers, etc. Conveniently, a life jacket can be stored in the node 72 personal services.

As shown in Figure 19, the table 75 comprises two parts 75a and 75b, attached deadlights together, the outermost part being pivotally mounted in the domestic services node device "lift and drop". That is, the two parts 75a, 75b table can be stacked together and then they can be turned up for vertically lowering in storage under a cover (not shown) in unit 72 of personal services. When the table is again needed it can be lifted out of the storage area, rotated into the horizontal position and the two parts are arranged, ready for use. Any other well-known device for storing the tables used in aircraft may, of course, be used instead of the device to "lift and drop" at will.

Monitor television shows such as 76 mounted on the rotational handle 78 at a node of household services 76 72. Monitor provides passenger entertainment during the flight and, optionally mounted as shown. Alternative arrangements where the monitor 76 retracts into the unit 72 of personal services or where the monitor 76 is attached removability, e.g., to the node 72, may be used instead.

Using the unit 72 auxiliary table or personal services to deploy a large number of seats around the auxiliary parts. Complete removal of the monitor from the table and reduces the load on the seat by removing the seat load these household services. Armchair and assembly of household services, so act together to ensure that the seating unit that offers a comfortable and healthy environment for passengers traveling.

Assembly 70 includes a pair of flaps 79, 80 approximately at the height of the head of a passenger sitting upright on a chair. The flaps 79, 80 increase the feeling of privacy for occupying the passenger seat. Lamps 81, 82 may be provided in the shields for use by the passenger if desired.

20 illustrates how several pairs of seating units may be arranged along the center of the cabin. The zone is defined by each passenger seat 71, the node 72 personal services, 83 node back to the front seat, and partitions 84, 85 extending from the rear of the units 83 to 72 seats to the assembly of consumer services. For reasons that will become apparent from the description that follows hereinafter the upper part of each seat defines a ridge 86 in the rear side of the seating unit. Place below ridge 86 can remain open, as shown in Figure 20, or may be partially closed to provide in both cases a manual storage briefcase (or similar) for the passenger in the seat behind. Equipped with a spring clip 88 can be provided to store your carry briefcases and the like placed in the storage area. Other storage space for items such as a life jacket can be provided in the handlebars 88a, 88b of the seat.

Although the overlapping arrangement shown in Figures 3 and 4 is preferred, can, of course, other devices used for seating. Figure 22 shows an arrangement in which a central series of seats comprising pairs of units 90, 91, 92, located along the central axis 93 of the cabin, and three individual assembly 94, 95, 96 and one pair of units 97 are placed along each side of the cabin. Storage node 98 is placed forward of the front of the central pair of units 90 for privacy. Similarly, the partition 99 is placed in front of the side pair of units 97 and beside the single seat 96 to provide privacy especially for the occupant occupying the seat 97a. The baffle 99, which can be seen more clearly in Figure 23, is placed close to the side console 100 beside a chair 96 and fixed to the rear plate 80 of the chair. Additional storage space may be provided in the side console 100 if desired.

From Figure 23 it can be seen that the chair 96 can be folded back by a similar method, which can be folded back for seating units shown in Fig.1-17. Like the previously described seats, seat 96 comprises a fixed structure or a niche 101, which houses a 102 seat back, the seat portion 103 and the footing 104. Folding chairs sitting back is controlled using the control panel 105 (see., For example. FIG. 20) which controls the starting of motors and driving of shafts in a manner similar to that described above with reference to Fig.14-17.

The manner in which the chair back 86 reclines can be seen clearly in Figure 24 and 25. In Figure 24 a passenger 110 is shown sitting upright in a seat 111 and another passenger 112 is shown in a reclined position in another seat 113. In FIG. 25 shows the 114 passenger sitting upright in a seat 115 and passengers 116, 117 are shown lying in their respective seats 118, 119.

When the 113 seat leans back, the backrest 102 is moving into the niche 101. This is one reason why the projection 86 formed in the upper part of the niche. When moving back into the niche, designed to seat portion 103 and footrest 104 are moving forward from a niche, the foot frame 104 is moved from a vertical to a horizontal position. Continued reclining chairs back in the end it leads to the fact that part of the seating 103 and the footrest 104 come to the position of seats for 118 and 119 on Figure 25. In this position, back 102, seat portion 103 and the footrest 104 together form a substantially flat sleeping surface inclined at a slight angle to the plane of the wing of the aircraft. This angle is not critical, but the steeper the angle the less space required between seating units. The study found that more than 8 ° angle from the horizontal is uncomfortable because passengers feel that they slide forward. If in mind that most aircraft are tilted by 3 °, this means that can be used by an angle of approximately 11 °.

On the chair in the sleeping position, shown in Figure 25, feet tall passengers reach their lower lip seat forward. This is another reason for the projection at each node for seating. The surface to sleep can be extended by providing on a chair in front of pawl assembly 120 of expansion acting (like the secondary seat in the embodiments shown in Fig.1-13) together with the support of 104 feet.

Constructions for seating assemblies shown in Fig.19-25, aesthetically different from the structures for seating assemblies shown in 11-13, but from the consideration of the foregoing description it is clear that these designs are very similar. Both designs provide desirable privacy for passengers. Both designs provide a reclining / reclining chair that does not disturb the other passengers in the area of ​​the front or rear seats when the seat is moved for folding / reclining position. Using partitions can increase even more privacy individual passenger. Provision of accessories is the chair of the assembly as a seating reduces the load of the seat, allowing you to have more room in the seat, provided the passenger.

Constructions for seating assemblies shown in Fig.19-25, do not include a secondary seat and do not provide a substantially horizontal sleeping surface. Instead, it may be provided with a snap-down extension. Also, even though the sleeping surface is flat, it is inclined at an angle to the horizontal. Both of these features reduce the amount of space required for each node to sit in the cabin that can accommodate more nodes in the space of the interior.

Although Figure 22 shows one arrangement of one design of seating units in an aircraft cabin, it is understood that other designs may be placed in this location can be used or other accommodation (such as a staggered arrangement) to this structure, the seating assembly. Features described with respect to one embodiment may, of course, be adapted for use in another embodiment, the choice of this design and location depends on aircraft type, which must be placed nodes seating nature safety and other factors, which are completely outside the scope of the invention .

After thus described the invention by reference to preferred embodiments it should be well understood that the subject embodiments are only examples, and that those changes and modifications which come to mind to those with appropriate knowledge and skills may be made without departing from the the spirit and scope of the invention as set forth in the appended claims and their equivalents.
