Claim 11

An arrangement for a stowable and removable vehicle seat, wherein said arrangement has a horizontal seat adjuster that is substantially hidden below the floor of the vehicle, said arrangement comprising: a longitudinally oriented slot in said floor; a reinforcement secured in said slot and extending below the vehicle floor, said reinforcement comprising a vertical side with a lengthwise channel running thereon; an elongate stationary rail affixed to said reinforcement; a slider rail interconnected with but shorter than the stationary rail, said slider rail being carried by a plurality of rolling bearings interposed between said rails; locking means to selectively position the slider rail at a plurality of predetermined positions, said positioning thereby adjusting the horizontal location of said seat unit; a plurality of seat mounting pins cooperatively secured to and extending laterally from said slider rail, said pins accessible from above with each rod having roller means on its unsecured end, said roller means being supported by the lengthwise channel of said reinforcement; and a vehicle seat, said seat having front and rear legs, front and rear releasable locking means for cooperatively securing said legs on said mounting rods, and whereby said seat, upon release of the rear leg locking means, can be reconfigured about its front legs to a vertical stowage position.

Claim 12

A seat arrangement as defined in claim 8 wherein said seat further comprises independent lock actuation means secured to the removable seat, said actuation means cooperating with the slider locking means to selectively allow adjustment of the seat position.

Claim 13

A seat arrangement as defined in claim 8 wherein said slider locking means comprises: a plurality of evenly spaced openings in said stationary rail; a lock pull spring secured to said slider rail; a locking pin secured to the lock pull spring, said locking pin releasably engaged in said openings; sleeve means to align the locking pin, said sleeve being secured to the slider rail; and pivotal cam means cooperating with the lock pull spring to selectively disengage the lock pin from said openings.

Claim 14

A seat arrangement as defined in claim 10 wherein said sleeve means further comprises a second locking means, said second means cooperating with the locking pin to engage the stationary rail openings only during extreme loading conditions.

Claim 15

A seat arrangement as defined in claim 8 wherein said reinforcement and said stationary rail are integrated into one continuously formed unit.

Claim 16

A fore and aft adjuster arrangement for a vehicle seat, the arrangement comprising: a first rail means oriented in a fore and aft direction generally fixed with respect to the vehicle, having at least one flange; a second rail means slidably mounted with respect to the first rail means, having at least one flange interconnected with the flange of the first rail means; a mounting pin with first and second ends, the first end of the mounting pin projecting from the second rail along a locationally fixed axis, the mounting pin providing means for mounting of a vehicle seat; and a third rail means fixed with respect to the vehicle generally parallel and spaced from the first rail means, the first rail means supporting the second end of the mounting pin for relative movement of the mounting pin with respect to the third rail means.
