Abstract: A seatback drive assembly includes a lower bracket, a seatback pivotally mounted to the lower bracket, and a lock cam pivotally mounted to the seatback. The lock cam holds the seatback in an upright position when the lock cam engages the lower bracket. A biasing spring moves the seatback to a folded position when the lock cam is disengaged from the lower bracket. The seatback drive assembly also includes a gear pivotally mounted to the lower bracket and having a set of gear teeth. A motorized pinion engages the gear and is driven by an electric motor.

Abstract: A vehicle seat has a seat frame assembly including a seat base frame that may be shifted between a raised position and a lowered position, and a seatback frame pivotally attached to the seat base frame and foldable from a vertical position to a position atop the collapsed base frame. The seat base frame is pivotally connected to the vehicle floor by at least one front pivot leg which is pivotally connected for rotation with respect to both the vehicle floor and the base frame. A motor is mounted in a stationary position on the vehicle floor and connected to provide a relative torque between the seat base frame and one of the at least one pivot legs for powered movement of the seat base frame to and from the use position and the stow position.
