Description

[0025] Further features of the present invention are shown in the figures, in which:

[0026] FIG. I shows a seat according to the invention having damping members and a rear-side suspension arrangement;

[0027] FIG. I.1 is a front view of the seat;

[0028] FIG. I.2 is a side view of the seat;

[0029] FIG. I.3 is a perspective view of the seat;

[0030] FIG. I.4 is a top view of the seat;

[0031] FIG. I.5 shows a damping member according to the invention in a strap;

[0032] FIG. I.6 shows a damping member according to the invention in the form of a wall suspension arrangement;

[0033] FIG. I.7 shows a seam arrangement of a damping member according to the invention in the form of a strap.

[0034] A damping member 1 that has two attachment points 2 is provided in FIG. I. Fastening elements 3 are at the attachment points 2 on each side of the damping member 1. A force absorber that damps the damping member 1 is located between the attachment points.

[0035] To this end, the force absorber can be designed as material of the damping member 1. However, it could also be integrated into the damping member 1.

[0036] The damping member 1 and the force absorber have a force limit up to which the damping member deforms elastically. Thus, in the event of action of force, the damping is achieved by this elastic behavior. If the exerted force exceeds the elastic limit, plastic deformation of the damping member 1 takes place. In this case, at least a portion of the exerted force is converted into plastic deformation of the damping member.

[0037] A seat 10 is connected to a wall of a vehicle by the fastening elements 3 that are on the damping member 1.

[0038] If there is an impact on the vehicle from the outside, the damping member 1 according to the invention renders possible absorption of the energy of the impact both owing to its elasticity and also owing to a possible plastic deformation of the damping member 1.

[0039] Plastic deformation is realized by the two longitudinal axes of the fastening elements 3 being sheared and this shearing having an elastic action up to a force limit and causing the deformation of the damping member 1 above the force limit.

[0040] The elastic and also the plastic deformation serve to reduce the deformation energy and therefore considerably attenuate the impact acting from the outside, so that the person sitting on the seat 10 is very well protected against this external influence.

[0041] In a further refinement, the damping member 1 is integrated into a strap 5 with which the person sitting on the seat 10 can strap in. Provision is made here for two layers of the strap material to be arranged substantially congruently one on the other in the region in which the strap 5 forms the damping member 1.

[0042] In this case, the strap 5 can be fastened to the seat, to the wall of the vehicle, to the chassis of the vehicle or in combination of the above.

[0043] A plurality of seam lines that connect the two layers of strap material, which are arranged substantially so as to fully cover one another, to one another are made transversely of the strap 5 at spacings from one another. Moreover, the strap 5 is usually connected first to the seat 10 and second to the chassis 11 or to the seat once again. To this end, the fastenings of the straps 5 form the fastening elements 3 of the damping member 1 and the ends of the strap 5 form the attachment points 2.

[0044] The plurality of seam lines that are parallel to one another and one after the other in the longitudinal extent of the strap 5 create a kind of predetermined tear point since the seams tear in succession as a consequence of the impact from the outside and in this way reduce the energy of the impact. During normal operation of the vehicle, this plurality of seam lines that are parallel to one another are dimensioned such that they do not tear in the normal case up to a maximum load with which the seat 10 may be loaded.

[0045] FIG. I shows a seat 10 of a vehicle, which seat is connected to the seat 10 by the damping member 1 by fastening elements 3 or the like. Second, the damping member 1 is likewise connected to a wall, not illustrated, of a vehicle by fastening elements or the like.

[0046] The illustrated seat 10 is also equipped with the damping member 1 that is integrated in the strap 5.

[0047] FIG. I.7 shows a possible seam arrangement for a damping member 1 according to the invention in the form of a strap 5. The seams that run parallel to one another and transversely of the strap 5 connect two layers of the strap 5 here. The strap 5 itself is multilayered in the region of the seams. This can be embodied by loops that the strap 5 forms in the region of the seams, but the strap 5 can also form the multilayered region by a plurality of strap pieces being laid one over the other in an overlapping manner.

[0048] In the event of action of force on the strap at the attachment points 2, a shear force is then exerted on the seams that can be separated as a result and implement the damping of the damping member 1. As shown, the seams can each connect two layers, but they can also be continuous through all layers. In this case, the different seams can be formed from different materials with different tearing behavior.

[0049] FIGS. I.2 and I.3 show a particularly preferred arrangement of the damping members 1 that are designed as the strap 5. In this case, the strap 5 is anchored on the seat 10 by its attachment points 2, and one end of the strap 5 is anchored to the backrest of the seat and the other end of the strap 5 is anchored to the seat 10. As a result, the seat 10 can be damped in the event of an action of force on the vehicle if the sitting surface of the seat 10 is of movable, for example foldable, design.

[0050] All the figures show that both the damping member 1 without the strap and the damping member 1 that is integrated into the strap 5 are used. The protective effect is considerably increased as a result. Second, it is also conceivable for only the damping member 1 without the strap or only the damping member 1 that is integrated into the strap 5 to be able to be used in the embodiments of the seat 10 shown. The combination can also be considered.

[0051] The invention is not restricted to the above-described features. Rather, further refinements are possible. For example, an additional absorption element can be associated with the absorption element in order to increase the damping. Plug connections at the attachment points and/or fastening elements are likewise possible in order to make possible easy replacement of the damping members. Finally, the use of a plurality of damping members in parallel or in series would be possible in order to adjust the damping in accordance with the intended use.
