Anchorage system for a seat belt

摘要

A vehicle seat has a frame mounted on the vehicle floor by a fore and aft seat adjusting mechanism. A reel is rotatably mounted on the seat frame. A flexible element has one end attached to the reel and the other end attached to the vehicle floor. A windup spring acts on the reel to wind and unwind the flexible element during longitudinal fore and aft adjusting movement of the seat frame and maintains the flexible element in a taut condition irrespective of the selected adjusted position. A pawl is pivotally movable into engagement of the reel to block unwinding rotation thereof. A seat belt strap is attached to the pawl so that loads imposed on the belt during occupant restraint actuate the pawl to the blocking condition whereby the flexible element is held at its then existing length to anchor the seat frame against movement relative the vehicle floor. Accordingly, a seat belt element such as a buckle strap can be mounted on the vehicle seat and the seat belt loads are transmitted to the vehicle floor without relying on the force sustaining capability of the seat adjusting track.
