A vehicle seat (101, 201), includes a seat height adjusting multi-bar linkage (4) with five transmission links (5, 6, 7, 8, 9), operative in normal operation as a four-bar linkage based on a locking unit (10) acting between at least two transmission links (7, 8). In the event of a crash a crash blocking unit (121) locks a vehicle-structure-fixed frame (5) and a rocker (8) to each other, such that the multi-bar linkage (4) acts as a three-bar linkage. A transmission link (7) is arranged between the frame (5) and the rocker (8). In the event of a crash, the multi-bar link (4) acts as a five-bar linkage because of a load-controlled release of the locking unit (10), whereby locking of the crash blocking unit (121) can be triggered independently of a load-controlled release of the locking unit (10) by an inertia-controlled pawl (125) of the crash blocking unit (121).
