SAFETY BELT

摘要

A safety belt for tightly holding an occupant of a seat for vehicles such as an automobile, said safety belt being equipped with a shock absorbing means having a rigid plastics foam body, a receptacle with a uniform cross-section and a bottom plate, and a pusher having a tapering face the projected area of which is less than 70 percent of the cross-sectional area of said plastics foam body, said foam body being held in said receptacle between the pusher and the bottom plate, said pusher being movable toward said bottom plate when a tension is generated by the movement of an occupant supported by the belt so that said plastics foam body is deformed and displaced by the passage of said pusher and the kinetic energy developed by the movement of the occupant is absorbed.
