Linear pretensioner for motor vehicle seatbelt restraint systems

摘要

A pretensioner for a motor vehicle belt restraint system mounted to a structure of the vehicle. The pretensioner is connected to a belt restraint component that is also connected to the belt restraint system. The pretensioner includes a conduit made of tubing and having first and second ends. At least a portion of the conduit defines an elongated piston bore with a piston slideably positioned therein. A cable is attached to the piston and extends through the conduit for connection to the belt restraint component. A micro-gas generator is also located within the conduit and positioned generally opposite of the piston. Upon activation of the micro-gas generator, a gas is generated in the piston bore and drives the piston such that the piston exerts tension on the cable and thereby on the belt restrain component.
