ABSTRACT:
A variable length anchoring device for vehicle seats having a forward and rearwardly adjustable seat portion, in which a hydraulic cylinder assembly is connected to the forward part of the seat portion and to an anchor means on the floor, or other suitable support rearwardly of the forward part of the seat. A deceleration responsive mechanism controls the hydraulic cylinder assembly so that the hydraulic assembly adjusts freely while the seat is being adjusted, but becomes a rigid member in an emergency, or during a sudden deceleration, resulting from the application of the vehicle brakes. In one embodiment, the opposite ends of the cylinder are connected by a conduit, and a valve connected to the brake system controls the flow of fluid through a conduit connecting one end of the cylinder to the other.
