ABSTRACT:
A vehicle seat has a sitting surface and a backrest which has a backrest upholstery with a forward upholstery arching arranged in the region of the lumbar vertebrae of the seat user for the purpose of relieving the user's intervertebral discs. For the physiologically most efficient back support for seat users of widely varying body height, without the need to carry out individual adaptation measures on the backrest, the upholstery arching is configured such that its contour vertex is located approximately 250 to 275 mm above the sitting surface and here is itself made so flexible that it easily matches the shape of the back of the seat user, and a relatively rigid pelvic support is formed in the upholstery arching approximately 150 to 175 mm above the sitting surface.
