- a deformation of the bolt-shaped portion 7 may be provided, as shown in Figures 13 to 15.
- a guide sleeve 7a with end-side flange regions is embedded in the continuation of two vertically extending ribs 4 for this purpose.
- the outermost rib 4 is interrupted in the region of the bolt-shaped region 7.
- a threaded bushing 7b is slidably disposed within the guide sleeve 7a.
- This threaded bushing 7b extends further inwards, beyond the guide sleeve 7a, up to a transverse rib 4c arranged perpendicular thereto.
- the threaded bushing 7b terminates more or less flush with the rib 4 arranged on the outside, adjacent to the bolt-shaped region 7.
- the threaded bush 7d has a flange region 7c on the inside, that is to say on the end facing away from the bolt-shaped region 7.
- This flange portion 7c abuts on said transverse rib 4c, which is provided in addition to the continuations of the vertically extending ribs 4.
- the transverse rib 4c is slightly further spaced than the two ribs 4 and also has a somewhat smaller thickness in the present case.
- a bolt 7d up to a bolt 7d formed on the flange In the threaded bushing 7b is screwed from the outside, by the interruption of the outermost rib 4, a bolt 7d up to a bolt 7d formed on the flange.
- the bolt 7d forms with the outside end said projecting, bolt-shaped portion 7, which in a lower Holder 6 can be positioned, as indicated in Fig. 10.
- the outer end of the bolt 7d can be connected via the holder 6 both detachable and fixed to the vehicle structure, wherein the bolt 7d is vehicle-fixed in the use position of the backrest.
- the transverse rib 4c in the area adjacent to the flange area 7c of the threaded bushing 7b is provided around the same with a plurality of openings, which forms a predetermined deformation or breaking point 14.
- a different design of the desired deformation or fracture parts is possible, such as by a perforation or by weakening material.
- a corresponding behavior of the predetermined deformation or breaking point 14 also occurs in the event of a frontal crash with a load in the area behind the vehicle seat, which presses on the backrest 1. Even in the case of a rear-end crash with a single-seated person, a corresponding behavior of the desired deformation or fracture point 14 can occur.
- the predetermined deformation or breaking point 14 may also be formed such that only an at least partial plastic deformation of the material occurs without tearing, ie without breakage. Also a plastic see deformation can dampen the impact suitable. Of course, a partial tearing may also be provided.
- the above-described configuration of the predetermined deformation or breaking parts 14 can also be used with another structure of the backrest.
- the ribs may be formed on a back shell instead of on a shell, or the back shell may also be omitted, i. the backrest can also be formed with a single shell.
- other materials are also suitable, such as, for example, light metals, metals, e.g. Steel, or composites.
- such a predetermined deformation or fracture parts can also be arranged elsewhere, ie, for example, instead of above, as described above.
