Upholstered seat, in particular an upholstered bench for vehicles

p0001The invention relates to a padded seat, in particular an upholstered bench, to vehicles with, notably motor vehicles, which are designed as travel or mobile homes, with a seat cushion and a back cushion, in each of which a dimensionally stable base, for example, a frame or a plate, the actual Risterung, as a foam pad, bears, and in which the main body of the back cushion keeps in its upper edge zone over its entire length an essay body formed of a plastically deformable Schichtkörperwerksktoff as impact damper, wherein the base body, attachment body and upholstery together and from a reference case, for instance from fabric, leather / or plastic, is surrounded.

p0002Vehicles, primarily Kraftfahrzeuge mainly to Personenbeförderung used are intended to have in its interior certain Sicherheitsanforderungen meet, thus entering accidents Personenschäden weitestgehend avoided, but at least be considerably reduced can.

p0003obtained particularly the impact areas of the head in the interior of the person sitting in the car people, ie, all non-glass surfaces of the vehicle interior, with which the head of an in particular seating position in the vehicle caregiver can come in caused by accidents relative accelerations in contact have an interpretation, reaching the order of milliseconds delay values ​​g are equal to or less than 80th It is therefore necessary to make the head impact area so each lying in the vehicle to placierenden caregiver inner surfaces of the vehicle and also of any equipment or facilities that ensure a sufficiently large deformation this without breaking and splintering.

p0004These security requirements apply in particular to the designed as a so-called travel or poppy Mobile motor vehicles which are regularly equipped with a padded seats, in particular upholstered benches, running seating that allow for the possibility of seating variation. The lengthwise direction of the vehicle successively arranged seating areas are namely, for example. According to DE-GM 77 37 061 designed so that they can be brought at least in a so-called driving position and in a so-called living position and in most cases even an arrangement in allow the so-called sleeping position. In driving position, the seating, the upholstered seats and / or upholstered seats are adjusted so that they are in the same direction with position in the direction of travel behind lying back pad. In the residential position, however, two adjacent in the longitudinal direction of the vehicle upholstered seats and / or upholstered benches have mutually mirror image setting, ie the cushion seat forward facing front located and the bench has a setting in which the back cushion of the direction of travel is turned while it or the other upholstered seat in the direction averted position remains. the other upholstered seat.

p0005For Schlafstellung can be two in the direction of travel hintereinander located Polstersitze or Polstersitzbänke up so that three-seat or BACKREST same level close hintereinander lie, while the fourth seat or BACKREST gegebenenfalls in a slightly inclined position can be brought, in order to act as as increased head support.

p0006The invention aims to provide a cushion seat, in particular an upholstered bench of the type indicated at the outset that, to ensure the safety requirements for the head impact area when used in vehicles, principally in motor vehicles which are as travel or motorhomes in use, if all Polstersitze, especially Polstersitzbänke, the variable Sitzgruppe in their so-called Fahrtstellung are accommodated.

p0007To achieve this object is provided according to the invention by the characterizing part of claim 1 in that the attachment body ironing exclusively from a cross-section or loop-shaped composite profile is that with the two legs comprising the rim of the base body and is present in it, and that more then the clear profile height the rim of the base body at least equal to the greatest, clear tread width is measured.

p0008Particularly, it has been proven by the invention if according to claim 2, the clear profile height of the composite profile on the rim of the base larger than its possible _Profilbreite is dimensioned.

p0009according to claim 3 an important training feature of the invention is seen in that the layer body profile consists of sheet metal and has a wall thickness of at most 1 mm, preferably has a wall thickness between 0.4 and 0.8 mm. Notably, a composite profile has practically proven, its wall thickness is in execution in steel 0.6 mm.

p0010In a further embodiment of the invention as claimed in claim 4, that the internal profile height of the composite profile corresponds to a multiple, for example twice, the clear profile width, according to claim 5, the clear profile width of the composite profile in its curved, namely a convex circular arc following end sized larger than the contact area of ​​its legs on the base body. Here, the two legs of the close_Schichtkörperprofils tangentially to the convex curved end and can to the composite profile bearing body toward obtain a light-concave curved shape in the direction. It is particularly advantageous thereby according to claim 6, if the clear width of the profile composite profile corresponds in its convex end region about a half times the clear profile width in the contact area of ​​its legs on the base body. Finally, it is provided according to claim 7, the free ends of the composite profile are completed by one and / or plugged plastic caps, which can be on the one hand with the inside formed on their edge of the shell cams in holes at the end of the composite profile lock, and the other by their ground on body attached, for example. can be screwed.

p0011Further features and advantages of the invention will be explained in more detail in an embodiment shown in the drawing. It shows<ul><li>Figure 1 a schematic side view a designed as travel or camper van with two longitudinally of the vehicle behind the other and arranged behind the cab upholstered benches in the skiing position,</li><li>Figure 2 is a similar to Fig. 1 illustration, however, the two upholstered benches are placed relative to each other in the housing position,</li><li>3, once again one of the Fig. 1 corresponding representation, but in which the two relative to each other in the Polstersitzbänke Schlafstellung are accommodated,</li><li>Figure 4 substantially full-scale marked in Fig. 1 with IV range of the back cushion a cushion seat in cross-section and</li><li>5 shows a section along the line VV in Fig. 4 by the corner portion of the back pad of a cushion seat.</li></ul>

p0012In FIGS. 1 to 3 of the drawing area set as travel or camper van 1 is depicted. This minibus 1 is in the driver's cab with the usual upholstered seats₂ fitted, which can be configured either as single seats, or also as a bench, each of which has a seat cushion 3 and a back cushion. 4

p0013Inside the Kleinbusses 1 behind the Fahrerkabine and Fahrzeuglängsrichtung hintereinander remain two variable Sitzgruppen 5 and 6 untergebracht, each consisting of several individual nebeneinanderstehenden Polstersitzen consist can, but preferably as mehrsitzige Polstersitzbänke running. Each Polstersitz or Polstersitzbank the Sitzgruppe 5 is on a Sockelkasten 7 is mounted, which rests on the Fahrzeugboden and in längsverlaufenden bearings Guideways displaceable and lockable held. Also, each seat cushion and the cushion bench seat group 6 is arranged on a base casing 8, which rests on the vehicle floor and is held there either in guide rails ver pushed or stationary.

p0014The Polstersitze or Polstersitzbank the Sitzgruppe 5 each have two Polsterkörper 9 and 10, while the Polstersitze or Polstersitzbank the Sitzgruppe 6 correspondingly two Polsterkörper 11 and 12.

p0015The two padded bodies 9 and 10 of the upholstered seats and upholstered seat the seating area 5 as well as the two cushion bodies 11 and 12 of the upholstered seats and upholstered bench seat group 6 are connected to each other and with the associated base box 7 or 8 by special fittings which allow, the cushion body 9 and 10 and 11 and 12 relative to each other as well as relative to the socket boxes 7 and 8 to be brought into different angular positions. the so-called traveling position of the seating 5 and 6 is seen from FIG. 1,. In this driving position, all upholstered seats or upholstered benches of the two groups of seats 5 and 6 are set so that they can be filled only with a view in the same direction. In the seating area 5 in each case the cushion body 9 forms the seat cushion, while the cushion body 10 is effective as a back cushion. In the seating 6 of the cushion body 11 serves as a seat cushion, while the cushion body 12 forms the back pad.

p0016As Fig. 2 of the drawing, the so-called residential position of the two groups of seats 5 and 6, in which the cushion seats or upholstered seat the seating 5 is set mirroring the upholstered seats or upholstered seat the seating 6.

p0017Thus in the living relationship between the two groups of seats 5 and 6 sufficiently footwell is located opposite sedentary persons and there possibly also a table can be erected, the upholstered seats and the cushion bench seat group 5 by means of its base box 7 from the position after FIG. 1 is shifted toward the driver's cab in the position according to FIG. 2._'

p0018In the residential position of FIG. 2, the padded seats and the cushion bench seat group 6 take the same rank as in the driving position shown in FIG. 1. The cushion body 11 forms here namely the seat cushion, while the cushion body 12 is effective as a back cushion.

p0019In the Polstersitzen or Polstersitzbank the Sitzgruppe 5 is in the Wohnstellung however Gebrauchslage the Polsterkörper 9 and 10 gegenüber the Fahrtstellung according to Fig. 1 interchanged, ie the Polsterkörper 10 here forms the Sitzpolster while the Polsterkörper 9 as BACKREST effective.

p0020In the sleeping position according to FIG. 3, the cushion seats or _Polstersitzbänke the two seating areas 5 and 6 and their attendant ceiling columns 7 and 8 relative to each other placed in such a position that the cushion body 10, 11 and 12 about in the horizontal plane in close succession are, while the cushion body 9 takes up a slightly inclined position to a to make some increased head support for people lying.

p0021The cushion body 9, 10 and 11, 12 of the padded seats and upholstered benches in two groups of seats 5 and 6 each have a dimensionally stable base body 13, for example. A frame or a plate on which the actual padding 14 rests, which for example relatively thick. From a foam pad can be formed. The rigid base body 13 and the actual padding 14 are together surrounded by a reference envelope 15 which, for example. Of textile material, leather and / or plastic can be made as well, together with the base body 13 and the padding 14 each forms a cushion body.

p0022At least the formstabile Grundkoerper 13 of that Polsterkörpers in Sitzgruppen 5 and 6, which, when in Fahrtstellung located Sitzgruppen 5 and 6 in accordance Fig. 1 in Kopfaufschlagbereich a sitting person is transported, must for safety reasons be designed that it has a energieumwandelndes behavior, ie can accommodate a head impact under plastic deformation with delay values ​​g are equal to or less than 80th

p0023In the driving position shown in FIG. 1 located upholstered seats and upholstered benches of the seating 5 and 6 at least the base body 13 of the cushion body 10 d-er-seating 5 has received such an interpretation, because it in its operating position of the back pad in its upper edge in the head impact area people is, who take on the upholstered seats or upholstered seat the seating 6 place, as shown in Fig. 1 using a manikin 16 shown only schematically. It can be seen how 16 to the so-called H-point 17 that represents the hip of a person relocating the torso of the manikin, in an arc forward and his head can on the back pad forming cushion body 10 meet in the seating area. 5

p0024At least the upper Randzone on Grundkoerper 13 of the BACKREST acting Polsterkörpers 10 is over its entire length of a temple in Querschnitt or schlaufenförmigen Schichtkörperprofil 18 of plastically deformable material comprises, as clearly the Fig. 4 be removed can. This composite profile 18 can consist of sheet metal and have a wall thickness which is at most 1 mm, but preferably between 0.4 and 0.8 mm. Has proven the use of Schichtkörperprofils 18 from Stahlblech a Wanddicke of about 0.6 mm, because it namely a Aufschlaggeschwindigkeit of about 25 km / h was Verzögerungswert of less than 60 g of a static deformation of more than 50 mm is reached, if a study with the manikin 16 takes place.

p0025The clear Profilhöhe 19 over the Randzone 20 of Grundkörpers 13 should be at least equal to the clear Profilbreite 21 dimensioned to be. It is particularly advantageous if the clearance profile height is 19 designed to be larger than the inside width of profile 21 while a multiple, for example, corresponds to twice, the clear profile width 21st

p0026It has also proven advantageous if the clear width of profile 21 of the composite profile 'is dimensioned larger than the contact area of ​​its two legs 18 "on the side surfaces of the base body 13. The inside width of profile 21 in the curved portion 18' 18 in its convex curved end portion 18 of the layer - _körperprofils 18 can about a half times the clear profile width in the contact region of the legs 18 "correspond to the base body. 13

p0027It is useful also when the tangent 18 "is not straight on the convex curved end 18 'subsequent two legs, but rather receive a slightly concave curved shape in order to achieve a favorable deformation behavior of the composite profile 18th

p0028The Fig. 4 and 5 can still be seen that the free ends of the composite profile 18 expediently completed by an attached plastic cap 22 acres. their edge of the shell 23 has the inside molded cams 24 which engage in holes 25 of the composite profile 18th On the other hand, the bottom 26 of the plastic caps 22, for example. Are connected by screws 27 to the base body 13.

p0029Should also be mentioned that the composite profile can be connected 18 via its two legs 18 ", for example. By rivets 28 or by screw to the base body 13.

p0030Of course it is also possible, the plastically deformable composite profile 18 to be connected to the edge zone of a base body 13 which is designed not as a board, but for example. As a framework.

p0031Of course, it is within the scope of the invention, all the cushion body 9, 10, 11, 12 of the Sotzgruppen 5 and 6 belonging upholstered seats and upholstered benches equipped with a base body, its ancillary relevant with the optimal energy conversion layer body profile 18 equipped. Each upholstered seat or upholstered each seat can then be inside the minibus 1 arranged so that their respective acting as back cushion cushion body having a Energy-impact zone.
