Abstract: A seat apparatus is provided for a vehicle comprising a first mechanism for moving a seat horizontally relative to the floor of the vehicle and a second mechanism movably mounted to the first mechanism for moving the seat vertically relative to the floor of the vehicle. The second mechanism includes at least one link and a motor drive assembly operatively associated with the link to move the seat vertically. The seat apparatus further includes a third mechanism for moving a seat belt to adjust for vertical and horizontal movement of the seat in order to insure that the seat belt will remain stationary relative to an occupant seated on the seat. The third mechanism is responsive to the motor drive assembly for moving the seat belt simultaneously with vertical movement of the seat.
