Fore and aft adjustment mechanism and seat belt anchorage for suspension seat
First Claim
1. In a vehicle suspension seat having a seat member movable up and down and fore and aft relative to the floor of a vehicle in which it is mounted, the improvement comprising a pair of guide rail members adapted to be fastened to the floor of a vehicle, a pair of seat member supporting slide rail members interlocked with said pair of guide rail member for fore and aft sliding movement relative thereto, manually operable locking means for locking the ends of at least one of said pair of slide rail members to said pair of guide rail members in a selected position of fore and aft adjustment, lap belt support members fixedly mounted on each side of said seat member for movement therewith, a support member fixedly mounted on each end of said at least one slide rail member and load carrying means mounted between said lap belt support members and said support members which are mounted on said at least one slide rail member, said pair of guide rail members being adapted to receive and transmit to the floor of a vehicle to which said pair of guide rail members is adapted to be affixed, all of the loading of said seat and of an occupant held therein by a lap belt anchored to said lap belt support members, said occupant loading being transmitted to said pair of guide rail members by said load carrying means and by said at least one slide rail member.

Abstract
Fore and aft adjuster mechanism is capable of serving as the load carrying seat belt anchorage means for a suspension seat having a large amount of vertical travel for isolating the occupant from shocks and vibrations and substantial horizontal travel for adjusting the position of the seat fore and aft to the position most comfortable to a particular occupant. The mechanism insures that the seat belt will remain of the same tautness and angular position relative to the occupant regardless of the amount of fore and aft or vertical movement of the seat. The adjuster mechanism is positioned intermediate the seat base and the vehicle floor and includes a pair of fore and aft guide rails on its sides anchored to the floor and a pair of sliding cross rails anchored to the seat base. Cooperating locking pins on the cross rails and holes in the guide rails provide fore and aft adjustment of the cross rails on the guide rails. The rear cross rail also carries a link on each side which is pivoted at its free outer end to the seat belt attachment point on the seat base. The link allows for unhampered normal vertical and fore and aft movement of the seat while transferring the loading of the seat and occupant to the guide rails and floor in a crash situation.
