Abstract
A lockbar for a seatbelt retractor has an elongate joining member and two end pieces joined to the joining member at opposite ends therefore. The end pieces are made of a higher strength material than the joining member. The joining member may be made by extrusion and may be tubular or may be formed as a hollow member. The end pieces may be produced as forgings, die casting or plastic injection moldings or by other suitable methods. They can be produced from different materials and to different designs to suit the specification of the seatbelt retractor. Hence a single basic seatbelt retractor design can be employed for a variety of strength requirements by selecting appropriate end pieces and an appropriate joining member.
