Abstract
Abstract A seat adjuster mechanism for a bench-type vehicle seat includes a first adjuster track assembly mounting the driver's end of the vehicle seat to the vehicle and a second adjuster track assembly mounting the passenger's end. The track assemblies are curved about an axis extending transversely of the vehicle so that the pitch and elevation of the vehicle seat are changed as the seat is adjusted fore and aft. First and second swivel mechanisms connect the respective adjuster track assemblies to the vehicle seat. First and second lock pawls are associated respectively with the first and second adjuster track assemblies for selective engagement in notches in a notched lock bar to latch the seat in desired position. A latch operating device is provided which is actuable in one direction to unlatch both the first and second latch means to permit simultaneous bodily fore and aft adjusting movement of the seat on the first and second adjuster track assemblies. The latch operating device is actuatable in the other direction to unlatch only the first lock pawl of the first adjuster track assembly to permit forward adjusting movement of the driver's end only.

Claim 1
Independent Claim
368 words
A seat adjusting mechanism for a vehicle seat comprising: a first adjuster track assembly having a lower track mounted on the vehicle and an upper track, a first swivel means attaching the upper track of the first adjuster track assembly to one end of the vehicle seat, a first latch means acting between the upper and lower tracks of the first adjuster track assembly and having a normal latched position to lock the one end of the seat against fore and aft movement, a second adjuster track assembly having a lower track mounted on the vehicle and an upper track, a second swivel means attaching the upper track of the second adjuster track assembly to the other end of the vehicle seat and permitting simultaneous pivoting and lateral shifting movement of the other end of the seat relative the upper track of the second adjuster track assembly, a second latch means acting between the upper and lower tracks of the second track assembly and having a normal latched position to lock the other end of the seat against fore and aft movement, and latch operating means having a normal position corresponding to normal latched position of the first and second latch means and being connected to unlatch both the first and second latch means when moved in one direction to permit simultaneous fore and aft adjusting movement of the seat on the first and second adjuster track assemblies and to unlatch only the first latch member when moved in the other direction so that only the first end of the vehicle seat is moved fore and aft and the seat pivots about the first and second swivel means and is shifted laterally relative the second track assembly, and blocking means responsive to the relative pivotal position between the first end of the seat and the first adjuster track assembly and being effective to maintain the first latch means in unlatched position when the first end of the vehicle seat is pivoted relative the first adjuster track assembly to assure rearward return of the first end of the seat into transverse alignment with the second end of the seat before the first latch means returns to normal latched position.

Claim 3
Dependent Claim
246 words
A seat adjuster mechanism for a vehicle seat comprising: first and second adjuster track assemblies respectively mounting the first and second ends of the vehicle seat on the vehicle body, first and second swivel means respectively in connection between the first and second adjuster track assemblies and the first and second ends of the vehicle seat to permit pivoting movement of the vehicle seat relative the respective adjuster track assemblies, first and second latch means associated respectively with the first and second adjuster track assemblies, and being movable between latched and unlatched positions to permit fore and aft adjusting movement of the associated end of the vehicle seat, latch operating means actuatable to unlatch the first latch means to permit forward movement of the first end of the vehicle seat, the first and second means pivoting the first and second ends of the vehicle seats relative the respective first and second adjuster track assemblies upon forward movement of the first end of the vehicle seat, and blocking means responsive to the relative pivotal position between the first end of the seat and the first adjuster track assembly and being effective to maintain the first latch means in unlatched position when the first end of the vehicle seat is pivoted relative the first adjuster track assembly to assure rearward return of the first end of the seat into transverse alignment with the second end of the seat before the first latch means returns to normal latched position.
