Abstract: The invention relates to a foldable vehicle seat comprising a base structure, a cushion support member, front support arms, which are each hinged to the cushion support member on the one side and at a front hinge to the base structure on the other side, a carrier member, which is hinged at an upper hinge point to the base structure and at a lower hinge point to the cushion support member, and with a seat back, which is pivotally hinged to the base structure, more specifically, to the upper hinge point. The carrier member comprises a control region having a front flank and a rear flank. A projection is formed on the seat back that extends into the control region, while fitting against the front flank in the normal position and coming to bear against the rear flank when the seat back is tilted forward a first angle; further, the projection pivots together with the carrier member when the seat back is tilted farther forward.
