Abstract
Abstract A seat adjuster particularly adapted for motor vehicle seats. The seat adjuster enables fore-and-aft movement of the seat and also provides an anchorage point for a seat belt restraint system which moves with the seat during adjustment. The seat adjuster includes a fixed base adapted for attachment to the vehicle's floor pan which forms an elongated toothed rack. A sliding rail which moves along the base includes a latching mechanism. The latching mechanism has a latching plate which is movable vertically and includes engagement features which mesh with the toothed rack on the base. In the normal condition, the latching plate is in an upward vertically moved position in engagement with the toothed rack thereby setting the adjusted position of the seat and providing firm support for the seat belt anchorage attached to the latching mechanism. When adjustment is desired, a release bar is actuated which moves the latching plate downward thereby disengaging the engagement features. The seat adjuster mechanism accordingly combines the functions of the seat adjuster and seat belt anchorages to provide an efficient and structurally secure seat adjuster.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
259 words
A seat adjuster for a motor vehicle seat assembly enabling fore-and-aft adjustment of the seat and providing an anchorage point for a seat belt restraint system which moves with the seat during adjustment, comprising: a base having mounting means for attachment to a motor vehicle, a toothed rack on said base, a sliding rail slidably movable with respect to said base and adapted to be coupled to said seat, a latch mechanism carried by said sliding rail and having engagine means for meshiing with said toothed rack, said latch mechanism movable to an engaged position wherein said engaging means meshes with said toothed rack thereby coupling said base and said sliding rail together preventing seat adjustment, and to a disengaged position in which said engaging means engages disengages said toothed rack enabling said sliding rail to be moved along said base permitting the position of said seat to be adjusted, release means for moving said latch mechanism between said engaged and disengaged positions, a latch plate coupled to said sliding rail including anchorage means for enabling said seat belt restraint system to be attached to said seat adjuster and further including means for supporting said release means as said release means is moved between said engaged and disengaged positions and said latch mechanism including a latching plate having a slot with said anchorage means disposed through said slot whereby said anchorage means and said slot support said latching plate and allows said latching plate to be moved as said latch mechanism is moved between said engaged and disengaged positions.
Claim 2
Dependent Claim
259 words
A seat adjuster for a motor vehicle seat assembly enabling fore-and-aft adjustment of the seat and providing an anchorage point for a seat belt restraint system which moves with the seat during adjustment, comprising: a base having mounting means for attachment to a motor vehicle, a toothed rack on said base, a sliding rail slidably movable with respect to said base and adapted to be coupled to said seat, a latch mechanism carried by said sliding rail and having engagine means for meshiing with said toothed rack, said latch mechanism movable to an engaged position wherein said engaging means meshes with said toothed rack thereby coupling said base and said sliding rail together preventing seat adjustment, and to a disengaged position in which said engaging means engages disengages said toothed rack enabling said sliding rail to be moved along said base permitting the position of said seat to be adjusted, release means for moving said latch mechanism between said engaged and disengaged positions, a latch plate coupled to said sliding rail including anchorage means for enabling said seat belt restraint system to be attached to said seat adjuster and further including means for supporting said release means as said release means is moved between said engaged and disengaged positions and said latch mechanism including a latching plate having a slot with said anchorage means disposed through said slot whereby said anchorage means and said slot support said latching plate and allows said latching plate to be moved as said latch mechanism is moved between said engaged and disengaged positions.
Claim 3
Dependent Claim
19 words
A seat adjuster as set forth in claim 1 wherein said toothed rack is formed integrally by said base.
Claim 4
Dependent Claim
34 words
A seat adjuster as set forth in claim 1 further comprising a slide track attached to said base and interfitting with said sliding rail to permit sliding movement of said rail along said track.
Claim 5
Dependent Claim
52 words
A seat adjuster as set forth in claim 1 wherein said base forms an elongated slot with an upper surface thereof defining said toothed rack and wherein said latch mechanism moves in a vertical direction wherein said latching mechanism is moved upward to said engaging position and downward to said disengaged position.
Claim 6
Dependent Claim
55 words
A seat adjuster as set forth in claim 1 wherein said release means comprises a release bar extending forward and having a center portion for manual actuation by the occupant and pivotably affixed to said seat adjuster and an end coupled to said latch mechanism for moving said mechanism between said engaged and disengaged positions.
Claim 7
Dependent Claim
