  • Publication number: 20010030441
    Abstract: Apparatus for opening and closing a deck lid of a vehicle body. An elongated rack is mounted in a housing for longitudinal movement. A rotatable pinion meshes with the rack to move the rack longitudinally in one direction or the other depending on the direction of rotation of the pinion. A reversible motor rotates the pinion in opposite directions. The deck lid is attached to a pair of arms pivoted to the vehicle body. A link has one end pivoted to the rack and the opposite end pivoted to one of the arms. The deck lid is moved to open position in response to longitudinal movement of the rack in one direction or to closed position in response to longitudinal movement of the rack in the other direction.

  • Patent number: 6061963
    Abstract: A window regulator mechanism for raising and lowering a window that slides up and down in a hollow closure. The window regulator mechanism includes a base plate that supports a tape drive that pulls the window up and pulls the window down. The tape wraps around upper and lower rollers that rotate on axes that are substantially parallel to the length of the closure. Two slack take-up devices for the tape are disclosed. An alternate window regulator mechanism drives the tape with conformation and does not need any slack take-up.

  • Patent number: 6022166
    Abstract: A self locking forkbolt for pivoting the end of a pivoting seat back frame to a vehicle body includes a pin that is locked into a slot by the end of a hook that swings on a pivot axis across the slot, from an open to a closed position. A locking lever fixed to the hook moves with the hook, and a cam lever pivoted to the same pivot axis, located on to of the locking lever, has a striker edge that is engaged by the pin first as the pin is pushed into the slot. The force transfer connection between the cam lever and the hook/locking lever is indirect, consisting of a spring that is compressed by the pivoting cam lever to, in turn, push on the hook. The locking lever pops into a latched position as the hook swings closed, and the spring remains at least slightly compressed, reducing rattle of the pin within the slot.
