ABSTRACT:
With a back rest for a vehicle seat, particularly a motor vehicle seat, in order to be able to adjust the longitudinal profile on the side facing the seat user by means of a shaping body having a rigid shape, the shaping body (8) has support surfaces (17, 18) both on the side facing the upholstery (7) and on the side opposite the upholstery (7), which can be placed selectively in defined positions of the shaping body (8) relative to an upholstery support against support surfaces (15') of a support element (4). When one support surface (17) is in contact with the support surface (15') of the support element (4), the longitudinal profile is different than when the other support surface (18) is in contact with the support surface (15').
