ABSTRACT:
An emergency release and rotary actuator including a cylinder containing compressed gas or ignitable chemical material, a pressure tube and electrically fired detonation means for releasing the gas into such pressure tube or igniting the chemical material to release the gaseous products of combustion there under pressure into such pressure tube, a piston within such pressure tube, the shaft of which extends outside the pressure tube and carries a lug which engages diverging slots in closely surrounding tubes, all except one of which is rotatable, and a shaft, gear, pulley, or arm attached to one or more of the rotatable concentric tubes. An electrical impulse from a sensing or manual switch causes a detonating force releasing gas or igniting the chemical to drive the piston, the shaft lug of which moves through the diverging slots to rotate at least one rotatable concentric tube to operate a latch, tighten a strap or position a panel or air bag. The addition of an outer tube or container around the pressure tube to conduct gas from apertures in the pressure tube to inflatable and extendable tubes or containers after completion of piston travel permits a sequential function of inflating and extending such tubes or containers after rotation.
