ABSTRACT:
A vehicle seat has seating components, such as a seat piece (20), a backrest (22) and a leg-rest (24), which are adjustable as to their positions, particularly in their relative inclination, by at least one operating device (26, 44). A monitoring device monitors all the boundary geometries (50, 52) of the moving seat components which may cause collisions and which have given spatial constraints (54). The monitoring device controls the operating devices (26, 44) at all points to guarantee a collision-free movement of all seat components within the spatial constraints. The vehicle seat considered as a total system can undergo adjustment processes without a damaging collision occurring.
