Protection system

The present invention relates to a protective system from fatal influence of vertical accelerations directed to fixed indoor facility, especially in a human, which provided for this body resting on the supporting surface for the object is moved by the vertical guide and is attached to the cushioning member of varying length, carrier device which is connected with one of the walls of the room, and leaning the body, in addition to its vertical movement by the guide, is movable along the transverse rail.

It is known that seats in armored vehicles and seat aircraft catapults, including the back, have the possibility of movement along a guide on the support, and this movement under the influence of a mine explosion or operated catapult seat braked cushioning element with a variable length in order to limit the load due to acceleration to a safe value. Due to the limited possible length cushioning member due to the limited surrounding space and requires restrictions affecting human acceleration forces, such as security systems, such as the explosions of powerful mines and / or in small planes are not sufficient to prevent the fatal consequences for people inside the vehicle . In addition, the known security systems the damping element with variable length comes into effect before the time when acceleration force acting on the object to be protected or on the human spine, reach critical values, as a inertia mass body is sufficient to activate such a damping system.

Known protective system from the fatal effects of vertical accelerations which are located in the object, in particular the person (3), which is based on the area of ​​support body (7) for the object (3) connected to the damping element with a variable length (11), connected through the carrier (6) from the board (4) cover (2) through a vertical path (18) communicates movement direction, wherein the leaning body in addition to its vertical path of movement (18) directed in the transverse direction, the system of this type is known from US 2002/0021041.

The object of the invention to avoid this disadvantage and create a defense system that would be effective also in the vertical acceleration armored vehicle, due to which the limit loads are people in the vehicle before it was exceeded.

This objective is achieved in the protective system of the above kind as a result of the invention, in that on the basis of provided vertical guide and a transverse guide on the vertical distance from each other so that the body under load due to vertical acceleration of the space in which it is situated, in relation thereto performed as down movement and pitching movement, the carrier device is connected to the roof structure so that the vertical acceleration acting on the floor of the space and transmits it to the structure of the roof, thence transmitted to the carrier device.

Of course, in this regard, the term "vertical" is not limited to only sense the direction of plumb and, for surrounding an object space has the value "downward", exactly the same as the vertical acceleration due to a mine, for example, moving to lift the vehicle is not vertically in the topographic sense.

Favorable forms of the invention are the subject matter of claims for a patent and can be seen from the following description on the basis of a schematic view of an example of execution. It shows:

1 is a side view of a protective system and securable partial image of the space in which it is located, in the initial position of the load;

2 the image according to Figure 1 in the final position of the load.

Protective system executed on the basis of the present invention includes, for example, in the form of several, adjacent along the lateral side of one of the crew compartment 2 of the vehicle with an armored mine protection. Each protector system for the crew members 3 is provided with at least one carrier device 6 disposed longitudinally parallel with a side board 1 and fixed to the roof structure 4 of the vehicle primarily through a hinge 5 so that the seat 9, consisting of the cushions 7 and the back 8 and equipped safety belts, anchored at a certain distance from the floor panel 10 of the vehicle. The second hinge 12 to the side support 12 'is used for carrying additional side fastening device 6 in order that it under the influence of a mine could follow the changing distance between the two hinges 5 and 11 respectively and between the floor panel 10 and the roof structure 4 without deformation.

This mounting method is compared with protective systems fixed on the floor, it has a substantial advantage significant reduction acceleration energy caused by exposure to a mine explosion under the vehicle floor, as it comes to a vehicle seat and the crew member 3 by-pass path through the sides of the vehicle 1 , the roof structure 4, carrier 6 and finally through the cushioning member 11.

Cushioning member 11 at its lower end by a hinge 13 secured to bottom portion 14 of the carrier device 6, and its upper end with a damping mobility towards the lower end, via a hinge 15 is connected to the bracket 16, the seat carrier 9.

In order to provide damping of motion, for example, fixed to the slide axis 17 in the bracket 16 of the carrier 6 as a vertical guide provided in the longitudinal direction of rocker 18. Thus, the seat 9 with the rapid movement of the crew compartment 2 upward with respect to the carrier device 6, from the position shown in Figure 1, can execute a deflecting movement hindered cushioning member 11.

To run this relative vertical movement damped cushioning element 11 only at the time preceding the attainment of acceptable for members of the crew or the relevant member of the crew 3 limit, on the one hand provided appropriate damping characteristics of the damping element 11, on the other hand - a particular characteristic of the trajectory lower, aimed rear relative to the seat rail 19 to 9 base seat 20, allowing deviation of the seat back.

In accordance with an exemplary of the guide 19, it is at the beginning, that is, in its upper portion 21 may be relatively flat and then steep and at the end - the flat again. Thus it is essential, however, that the characteristics of the cushioning member 11 and the guide 19 must be accurately aligned with each other in view of the geometric data of the seat and are directed at minimizing the required vertical path cushioning member 11. Thus, the forces produced varying elements, which on the one hand impact on the seat 9 and crew 3, on the other hand - on the cushioning device 11 so that the damping device 11 sufficiently to repay the considerable vertical acceleration of the vehicle as a result of mine explosion due structurally more ways of damping than it would have been possible without distribution of forces.

It is understood that the inclusion of additional, rearward deflection and thereby quenching via cushioning member 11 of a mass seat 9 and the crew member 3 may be implemented in another way that is different from the rocker path by the guide 19 in the form presented, for example, using the system levers. It is also possible different arrangement amortized weight than is represented in the example as well as the use of additional agreed with each other damping elements.

Protective system described kind in an appropriately adapted embodiment is also suitable for protection of objects of another kind, so that the seat 7 can be performed in a resting body, for example, for receiving objects to which it is also possible fatal effect is too strong accelerations, such as objects containing explosive substance, or highly sensitive electronics.
