ABSTRACT:
A seat belt arrangement employs a seat belt buckle pre-tensioner which includes buckle anchor supported on a structural component of a vehicular seat. The buckle anchor is formed with a ratchet or saw teeth extending along a guide slot. A seat belt buckle is connected to the buckle anchor via a connecting leg rigidly secured on the buckle and movable along the guide slot of the buckle anchor. The connecting member is cooperated with a pivotal actuation lever, which is, in turn connected to a sensor assembly which mechanically actuates the pivotal actuation lever for causing pivotal movement of the latter carrying with the connecting member for retracting the seat belt buckle in a direction for increasing tension at a seat belt web.
