Abstract: A vehicle seat has a base, a seat structure supporting a seat surface, and coupling elements allowing height adjusting and tilt adjusting of the seat surface relative to the base. Height is adjusted by a six-member seven-way linkage having six pivots, wherein angular orientation of two adjacent coupling elements relative to each other in a first linkage can be changed by a first fitting, and angular orientation of two adjacent coupling elements relative to each other is fixed at a second linkage by a second fitting. Angle adjustment is by the six-member seven-way linkage having six pivots, formed by the seven coupling elements. Angular orientation of two adjacent coupling elements relative to each other at the first linkage can be set via the first fitting, and angular orientation of two adjacent coupling elements relative to each other at the second linkage can be changed by the second fitting.

Abstract: In the case of a vehicle seat, in particular a motor vehicle seat, having an articulated seat framework (3) and a backrest structure (7) which can be transferred from a seat position into a table position and/or a floor position by moving the seat framework (3) and/or the backrest structure (7), the seat framework (3) having a front foot region (15, 17) and at least one diagonal strut (31), the diagonal strut (31) being locked releasably to the front foot region (15, 17).
