ABSTRACT:
A seat belt mounting member such as a retractor frame or an apertured plate has an elongated slot extending generally in the direction of imposition of occupant restraint load and a load bearing wall at the end of the slot. A fastener extends through the slot and attaches the mounting member on a vehicle body structural member. A means such as coined tabs or a frangible glass disc is located in the slot in interposition between the fastener and the load bearing wall to define a normal position of the mounting member relative the fastener wherein the load bearing wall is spaced from the fastener. The frangible or deformable means has a predetermined limited load sustaining capability and is permanently altered upon imposition of a predetermined occupant restraining load upon the belt to provide a permanent record of load imposition and permit limited bodily shifting movement of the mounting member whereby the fastener traverses the slot to engage the load bearing wall and thereby anchor the seat belt for effective restraint of the occupant. According to the preferred embodiment of the invention a deformable means is provided by coining tabs in the mounting member adjacent the slots to project into the slot, the tabs being permanently deformed by the fastener to provide a record of load imposition. According to another embodiment of the invention, a frangible glass disc is mounted in the slot and is broken by the fastener to provide a record of load imposition.
