SEAT BELT ANCHOR MECHANISM FOR ADJUSTABLE SEAT
First Claim
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, 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.

Abstract
Seat belt anchor mechanism for vertically movable suspension seat having fore and aft adjustment feature provides an anchor point for a lap belt which is spaced from the vehicle floor and movable relative to the floor. The anchor point is on a guide member carried by a slide on the upper movable seat frame and is movable vertically with the seat suspension but remains stationary when the movable seat frame is adjusted fore and aft. The guide member and anchor point are carried at the end of a pivot link attached at its rearward end to the floor or rear wall of the vehicle at such an angle as to fully support the anchor point and eliminate the necessity for an auxiliary tether belt. The mechanism permits the lap belt to remain relatively stationary relative to the occupant, regardless of the amount of movement of the suspension.
