Abstract: A vehicle seat assembly includes a seat back pivotally supported with respect to a seat bottom and is attached to the vehicle by a mounting assembly. The mounting assembly includes a locking device mounted on an upper track that moves relative to a lower track. The locking device includes at least one locking tooth that engages one or more slots on the lower track so that the upper track and the seat are maintained in a fixed position relative to the lower track. The locking device includes a first release member for disengaging the locking device and adjusting the position of the seat. The locking device also includes a second release member which is responsive to pivotal movement of the seat back with respect to the seat bottom or is responsive to some other type of actuation member. As the seat back is pivoted toward the seat bottom, the second release member rotates with respect to the upper track and engages the locking device causing it to move from a locked position to an unlocked position.

Abstract: A vehicle seat assembly includes a seat back and a seat bottom and is attached to a vehicle support structure by a mounting assembly. The mounting assembly includes a first track and a second track supported for movement relative to the first track; the seat bottom being supported on the second track for axial movement with the second track. This allows the seat assembly to be adjusted forwardly or rearwardly by a seat occupant. The seat back can also be moved relative to the second track between an upright position and a recliner position. The seat assembly receives a seat load resulting from the seat occupant sitting in the seat with the seat back in the reclined position and/or from a forward movement of the seat occupant during a deceleration of the vehicle when the seat occupant is belted into the seat. First and second support members or mounting brackets are attached to the second track. A structural support beam is supported on the second track by the first and second mounting brackets.
