摘要

The four-way seat height adjustment for a vehicle seat has front (31) and rear (32) swivel mounted adjustment levers. They are joined to movable frame sections and are connected to locking and/or drive members. The front and rear height adjusters are so coupled over at least one connecting element (8) in the form of a coupling bar that the freedom of movement each possesses independently of the other is limited by a stop displaceable by the adjustment mechanism. USE/ADVANTAGE - vehicle seat adjustment mechanism which does not allow submarining in the event of a crash.
