The invention relates to a vehicle seat (101, 201), comprising a multi-bar linkage (4) for adjusting the seat height, which multi-bar linkage is defined by five transmission links (5, 6, 7, 8, 9), wherein the multi-bar linkage (4) is operative as a four-bar linkage in normal operation of the vehicle seat (101, 201) because of a locking unit (10) that acts between at least two transmission links (7, 8) of the five transmission links (5, 6, 7, 8, 9), and comprising a crash blocking unit (121), which, in the event of a crash, locks a vehicle-structure-fixed frame (5) and a rocker (8) as two of the five transmission links (5, 6, 7, 8, 9) to each other in such a way that the multi-bar linkage (4) acts as a three-bar linkage, wherein a further transmission link (7) of the five transmission links (5, 6, 7, 8, 9) is arranged between the frame (5) and the rocker (8), and wherein, in the event of a crash, the multi-bar link (4) can initially act 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. The crash blocking unit (121) can be locked independently of a load-controlled release of the locking unit (10) by means of an inertia-controlled pawl (125) of the crash blocking unit (121). |
