ABSTRACT:
A seat with a backrest and sitting surface, in particular for motor vehicles, wherein the backrest comprises a backrest frame and, disposed between it, elements forming an S-shaped backrest with a shoulder area that can be reconfigured in the forwards and backwards directions, and a lumbar spine area that can be reconfigured in the forwards and backwards directions, wherein the elements are swivel-mounted to rotate about an imaginary or real axis extending horizontally between the shoulder and lumbar spine areas and running through the backrest frame or parallel with it in such a way that, without changing an existing inclination setting of the backrest relative to the sitting surface, a reconfiguration of the lumbar area and/or the shoulder area in the forwards direction can be made automatically by reconfiguring the shoulder area and/or the lumbar area in the backwards direction.
