Abstract

A safety belt mounting structure for use in conjunction with a vehicle seat that is suspended to permit adjustment up and down, and fore and aft for passenger comfort. The structure includes a rigid link pivotally mounted to the vehicle frame and to the seat structure and adapted to absorb the kinetic energy of the passenger and seat in the event of collision or vehicle impact.

Claims

1. A seat belt anchor mechanism for pivotally anchoring one end of a seat belt to each side of a suspension seat having an upper seat support frame movable vertically and horizontally relative to a lower seat frame and to the floor of a vehicle to which the lower seat frame is adapted to be fastened, characterized in that said anchor mechanism comprises:

slide means including a guide member and a slide member slidable on said guide member;

one of said members being fixed to said upper seat support frame and the other of said members being pivotally connected by a rearwardly and downwardly directed rigid pivot link to the vehicle frame at a pivot point behind the seat;

and seat belt anchor support means integral with said other of said members and movable therewith;

said anchor support means being movable vertically in response to up and down movements of said upper seat support frame but remaining stationary relative to the lower seat support frame in response to horizontal fore and aft adjustment movements of said seat support frame; and

the pivot links on each side of said seat being positioned so as to receive all of the loading imparted to the seat belt by an occupant and transmit it to the vehicle frame.

2. A seat belt anchor mechanism in accordance with claim 1 wherein said guide member is elongated and is longer than said slide member.

3. A seat belt anchor mechanism in accordance with claim 2 wherein said slide member is mounted on said upper seat support frame.

4. A seat belt anchor mechanism in accordance with claim 3 wherein said pivot link is mounted to said vehicle floor by a bracket to which it is pivotally mounted.
