  • Patent number: 4290627
    Abstract: An L-shaped inflatable restraint cushion that is compartmentalized into a lower horizontally orientated compartment and an upper vertically orientated compartment that are interconnected and in constant communication with each other through at least one orifice.

  • Patent number: 4110934
    Abstract: A hinge and latch mechanism to guide one edge of a vehicle sliding door for initially moving the edge laterally away from a vehicle body during opening and subsequently guiding movement of the edge in a longitudinal direction along the vehicle body. A generally U-shaped link member is utilized to support the one edge, a leg of which is operably connected to the door while a second leg is operably connected to the vehicle body. The body-oriented leg has a cam member attached thereto interactive with a door latching arm to prevent longitudinal movement of the latch mechanism during initial pivoting movement of the door to a laterally outward position and to permit subsequent longitudinal movement after the initial lateral movement.
