Abstract
A pretensioner for a three point vehicle safety restraint seat belt has a mounting for one end of the seat belt. The mounting has a first member fixed to a load bearing part of the vehicle and a second member attached to the end of the seat belt. A force reservoir, such as a pyrotechnic unit, moves the second member relative to the first member in a pretensioning direction in response to activation by a crash sensor.
