ABSTRACT:
Mechanism for raising/lowering a seat structure. A motor-operated screw-nut assembly is operatively connected to the seat structure via a lazy tongs support system. Laterally spaced guide devices give the support system a desired wide-stance stability that prevents undesired lateral dislocation of the seat structure. The support mechanism is compactly arranged beneath the seat structure, whereby the assembly is adapted to be used in military vehicles.
