Embodiment Construction

[0031] figure 1 A perspective view is shown of an embodiment of a vehicle seat cross member 1 formed from a tubular base body 2 and reinforcement tubes 3 a, 3 b inserted into the open ends of the tubular base body 2 .

[0032] In this case, the reinforcing tubes 3a, 3b are inserted into the ends of the base body 2 and are connected to the base body 2 by a common deformation, in particular cold deformation. Here, the two different reinforcing tubes 3a, 3b jointly form with the base body 2 receptacles 6a, 6b with a polygonal cross-section and a cone 7, which likewise has a polygonal cross-section.

[0033] Furthermore, the reinforcing tube 3 a for forming the first receiving section 6 a has a flat receiving opening 8 for receiving the end of the torsion bar spring 5 extending within the base body 2 . The torsion bar spring 5 is arranged in the receptacle opening 8 in a torsionally locked manner and thus enables the intended use when the end of the torsion bar spring 5 opposite ...

Abstract

The invention relates to a motor vehicle seat cross-member comprising: a tubular base body and receptacle section arranged on the base body for the torsion-free arrangement of a coupling element. In order to provide a motor vehicle seat cross-section that can be economically produced and that has a low weight and a high strength, it is provided that the receptacle section has a reinforcing tube that is arranged coaxial to the base body and lies on its inner or outer surface, and a cross-section deviating from a circle that is produced by joint deformation, especially cold formation, of the base body and the reinforcing tube.

Description

technical field [0001] The invention relates to an automobile seat beam, which has the [0002] - a tubular base body, and [0003] a receiving section provided on the base body for providing the coupling element in a rotationally secured manner. Background technique [0004] Vehicle seat cross members of the type mentioned at the outset are used in various embodiments to form vehicle seats, wherein the vehicle seat cross member is transverse to the seat, in particular the seat bottom, with respect to the installation position of the vehicle seat on the vehicle. The frame extends in the vehicle direction. In a typical embodiment of the vehicle seat cross member, it extends between the lateral parts of the vehicle seat and accommodates suitable rocker arms in a rotationally secured manner, by means of which the vehicle seat can be adjusted, for example The height is adjusted, wherein for this purpose, the vehicle seat cross member is connected in a rotationally articulated...
