Embodiment Construction

[0041]A vehicle seat 1 for a motor vehicle, in this case a rear seat, has a seat component 3 and a backrest 4 which can be fitted to the seat structure 3 and is adjustable in terms of inclination . However, the vehicle seat 1 may also be a front seat. The backrest 4 comprises a backrest frame 40 and a base plate 30 configured as a planar object. The back frame 40 and base plate 30 are welded together, preferably by laser welding, to form the back structure.

[0042] In this case, the substrate 30 has a material thickness of approximately 0.35 millimeters. In this case, the base plate 30 comprises ribs and ribs 31 and is still intended to be considered planar. In this case, the backrest frame 40 has a material thickness of approximately 1.5 mm. Other material thicknesses of the backrest frame 40 are also conceivable, in particular between 0.8 mm and 4 mm.

[0043] The arrangement of the vehicle seat 1 in the vehicle and its usual direction of travel define the directional ...

Abstract

The invention relates to a backrest structure for a vehicle seat (1), comprising a flat base sheet (30) and another structural part (20, 40) which are connected to each other by at least one weld seam (50) using a laser welding procedure. In the process, at least one tongue (28, 36, 38) of the base sheet (30) is bent by 180 degrees in the region of the weld seam (50) and placed on the remaining base sheet (30), and the at least one weld seam (50) connects the bent tongues (28, 36, 38), the remaining base sheet (30), and the other structural part (20, 40) to one another. The invention additionally relates to a vehicle seat (1) with such a backrest according to the invention.

Description

technical field [0001] The invention relates to a backrest structure suitable for a vehicle seat having the features of the preamble of claim 1 and a vehicle seat having the features of claim 15 . Background technique [0002] DE 10 2005 005 485 A1 discloses a backrest structure suitable for the backrest of a vehicle seat with at least one base plate and a backrest frame comprising lateral top hat profile members extending vertically on the left and right and an upper part extending in the transverse direction and lower top hat back member. A top hat profile member is welded to the front side of the base plate. The transverse top-hat profile-member is welded to the top-hat profile-member extending in the transverse direction. [0003] DE 10 2006 000 850 B4 discloses a backrest structure with a one-piece construction, substantially peripheral frame. The frame extends at three edge regions of the base plate and comprises two longitudinal sections extending in a parallel man...
