An improved manually adjustable vehicle seat assembly is disclosed. The adjustable vehicle seat assembly includes a vehicle seat, track assemblies each with a stationary track fixed to a vehicle floor and a translating track slidably interconnected with the stationary track, a horizontal adjustment mechanism that provides an occupant of the seat with the ability to position the translating tracks horizontally relative to the stationary tracks, a seat support structure, including forward and rearward seat support arm assemblies, for supporting the seat on the translating tracks, and a vertical adjustment mechanism having forward and rearward sector gears coupled with the forward and rearward seat support arm assemblies respectively, forward and rearward locking members mounted so as to be selectively engageable with the corresponding sector gear to prevent movement of the sector gear, and seat support arm assembly coupled thereto, when engaged, forward and rearward camming members mounted so as to be selectively moved to either engage or disengage the corresponding locking member, a resilient coupling between the camming members, a lever actuated control member, an actuating lever, and a fore and aft motion transmitting member coupled with the lever actuated control member and the camming members by pin and slot connections so that upon movement of the lever actuated control member one camming member is moved so as to disengage a corresponding locking member while the other camming member continues to hold the corresponding locking member in the engaged position. |
