ABSTRACT:
A motor vehicle seat with a backrest contains a spring core and has forwardly curved side parts into which inflatable air cushions are inserted for varying the contour of the backrest. The air cushions are arranged between fixed uprights and the spring core. As a result, in the event of variations in the filling pressure in the air cushions the overall shape of the spring core is varied. The horizontal contour of the backrest can thus be varied to a greater degree than previously with air cushions in the upholstery, without the surface hardness of the upholstery being adversely affected.
