Abstract
A seatbelt pretensioning retractor assembly for use in a passenger vehicle is provided. The pretensioning assembly includes a tube in fluid communication with a gas generator and a driving element disposed therein that travels in a first direction in response to actuation of the gas generator. The driving element includes a polymer rod. A stopper is coupled to an end portion of the polymer rod. In one example, a seal member is disposed between the gas generator and the stopper. In another example, the tube has an opening that is adjacent to an exit to facilitate venting gas from the gas generator.
