ABSTRACT:
An adjusting mechanism is disclosed for automatically raising the arm rest of a vehicle front seat assembly when the seat back is tilted forward to permit ingress to and egress from the back seat of a two door motor vehicle. In one embodiment a solid link is attached to the arm rest and to the seat cushion to exert an upward force on the arm rest as the seat back is moved forward. In two other embodiments, a cable attached to the arm rest and to the seat cushion is provided which exerts an upward force on the arm rest as the tension in the cable increases when the seat back is rotated forward. In one embodiment, a spring is used to maintain the tension in the cable at a predetermined level.
