ABSTRACT:
An actuator for a seat belt tightening device for a vehicle using a piston received in a cylinder so as to be actuated by an explosive expansion of a propellant in a chamber defined in the cylinder behind the piston. To ensure a required strength of the coupling between the piston and a cable for transmitting the actuating force and to simplify the process of attaching the cable to the piston, the piston is cast by metal or alloy with an end of the cable embedded therein. Thus, the piston may be used as cast and no extra work is required to tie the cable to the piston. To improve the sealing capability of the piston, a skirt having a flared edge made of synthetic resin may be attached to the rear end of the piston.
