ABSTRACT:
A seat belt pretensioner has a rotary member that is connectable to a safety belt webbing retractor. A spool and a number of vanes are hingedly attached to the rotary member at spaced positions around the circumferential periphery of the rotary member. The rotary member is rotatably mounted in a housing having a wall facing, and spirally formed with respect to, the rotational axis of the rotary member to form a circularly tapering gas chamber between the rotary member and the wall of the housing. In the event of a crash a gas generator supplies gas which impinges upon vanes attached to the rotary member and causes the rotary member to rotate.
