5 . The seat adjustment system of claim 4 , wherein upon release of the actuation device, the latching device is pivotally biased in a downward direction such that the plurality of projections engage a different subset of the plurality of slots to lock the cushion pan in a different fore-aft position.
6 . The seat adjustment system of claim 5 , wherein the latching device includes a first projection and the seat locking device includes a second projection, wherein the first projection engages the second projection to limit a forward travel of the cushion pan.
7 . The seat adjustment of claim 1 , wherein the seat locking device includes a plurality of locking slots defined in a second side wall, wherein the second adjustment mechanism includes a seat adjustment device attached to a top portion of a platform of the seat assembly and having a protruding projection that engages one of the plurality of locking slots to lock the seat assembly at a desired tilt angle.
8 . The seat adjustment system of claim 7 , wherein the seat adjustment device includes an actuating device to facilitate the engagement and disengagement of the protruding projection with the one of the plurality of locking slots.
9 . The seat adjustment system of claim 8 , wherein upon actuation of the actuating device, the protruding projection disengages from the one of the plurality of slots to thereby allow pivoting of the seat assembly to adjust a tilt angle of the seat assembly.
10 . The seat adjustment system of claim 9 , wherein upon release of the actuating device the protruding projection is biased into a different one of the plurality of locking slots to thereby lock the seat assembly at a different tilt angle.
11 . The seat adjustment system of claim 10 , wherein the actuating device is a cable assembly.
12 . A vehicle seat system comprising:
a seat assembly having a seat base and a seat frame assembly;
a seat locking device;
a seat slide mechanism cooperating with the seat locking device to adjust a fore-aft position of the seat assembly; and
a seat tilt mechanism cooperating with the seat locking device to adjust a tilt angle of the seat frame assembly with respect to the seat base.
13 . The vehicle seat system of claim 12 , wherein the seat locking device includes a plurality of projections extending upward from a first side wall, wherein the seat slide mechanism includes a latching device attached to a slidable cushion pan and having a plurality of slots defined therein, and wherein the plurality of projections engage a subset of the plurality of slots to lock the slidable cushion pan in a fore-aft position.
14 . The vehicle seat system of claim 13 , wherein the seat slide mechanism further includes an actuating device, wherein upon actuation of the actuating device, the latching device pivots in an upward direction thereby disengaging the plurality of projections from the subset of plurality of slots to facilitate movement of the cushion pan in the fore-aft direction.
15 . The vehicle seat system of claim 14 , wherein upon release of the actuation device, the latching device is pivotally biased in a downward direction such that the plurality of projections engage a different subset of the plurality of slots to lock the cushion pan in a different fore-aft position.
16 . The vehicle seat system of claim 12 , wherein the seat locking device includes a plurality of locking slots defined in a second side wall, and wherein the seat tilt mechanism includes a seat adjustment device attached to a top portion of a platform of the seat assembly and having laterally a protruding projection that engages one of the plurality of locking slots to lock the seat assembly at a desired tilt angle.
17 . The vehicle seat system of claim 16 , wherein the seat adjustment device includes a cable assembly, wherein upon actuation of the cable assembly, the protruding projection disengages from the one of the plurality of slots to thereby allow pivoting of the seat frame assembly with respect to the seat base to adjust a tilt angle of the seat frame assembly.
18 . The vehicle seat system of claim 17 , wherein upon release of the cable assembly, the protruding projection is biased into a different one of the plurality of locking slots to thereby lock the seat frame assembly at a different tilt angle.
19 . A method of adjusting a tilt angle of a seat assembly comprising:
activating an actuation device on a seat adjusting mechanism;
disengaging a protruding projection on the seat adjusting mechanism from one of a plurality of slots in a seat locking device;
adjusting a tilt angle of a seat frame assembly with respect to a seat base of the seat assembly;
releasing the actuation device;
biasing the protruding projection in a different one of the plurality of locking slots; and
locking the seat frame in a different tilt angle.
20 . The method of claim 19 , wherein the actuation device is a cable assembly.
