ABSTRACT:
A cylinder-piston assembly of a gas-operated actuator for straining a seat belt when a vehicle encounters a collision is provided with gas passageways which are normally closed by a valve. The valve permits gas to escape through the passageways when the gas pressure exceeds a predetermined value due to pulling of the piston against the force developed by the gas during forward motion of the seat occupant so that the occupant may be secured to the seat with a restricted force and adequate energy absorption.
