Abstract
An apparatus comprises seat belt webbing (12) for restraining movement of a vehicle occupant. The apparatus also comprises a pretensioner (10) for pretensioning the belt webbing (12). The belt webbing (12) has a portion (84) extending through the pretensioner (10). The pretensioner (10) includes an air bag (52) having a deflated condition and an inflated condition. The air bag (52) when in the inflated condition acts on the belt webbing portion (84) to draw belt webbing into the pretensioner (10) to tension the seat belt webbing, and causes the belt webbing portion to be blocked from being pulled out of the pretensioner. The pretensioner (10) includes an inflation fluid source (54) actuatable to supply inflation fluid to inflate the air bag (52) into the inflated condition.
