ABSTRACT:
A land vehicle seat assembly for absorbing explosive shocks is mounted on e vehicle's floor. The assembly has an anti-friction pad on the floor. A base plate on the pad swings around a pin fixed to the floor at the front of the plate. Horizontal shock absorbers at either side of the plate deceleratingly retard swinging of the plate. Stops at the sides of the plate limit plate swing. The assembly includes a pair of upright rails fixed to the plate and a seat slidable on the rails. A light duty unit such as a pneumatic spring or a shock absorber connects to the plate and seat. A heavy duty shock absorber, responsive only to shocks above a certain power, is connected to the plate. The heavy duty shock absorber can absorb shocks an order of magnitude greater than does the light duty unit.
