Abstract
A pretensioner for a vehicle safety restraint comprises a cylindrical hollow tube, a piston member located within the tube and connected via a cable to a part of the vehicle safety restraint, and a pyrotechnic charge which is activated in the event of a collision to evolve a volume of gas within the tube to move the piston from one end of the tube to the other, wherein a pressure relief port is provided in the tube at a point along its length which is close to the end of the tube toward which the piston is moved on activation of the pyrotechnic charge.
