HEAD IMPACT PROTECTION FOR AN AUTOMOBILE SEAT BELT ANCHOR FASTENER

摘要

A fastener bolt for an automobile seat belt anchor is provided with an annular energy-absorbing cushion on the front surface of the bolt head. In a crash situation, forcible movement of a vehicle occupant's head against the cushion will have a lessened tendency to cause human injury or pain. The annular cushion has a central access opening that registers with a non-circular cavity in the bolt head, such that the fastener bolt can be screwed into a hidden fastener nut while the cushion is in place on the bolt.
