  • Patent number: 6679531
    Abstract: A vehicle compartment latch has a support that is fastened to a deck lid. A fork bolt is pivotally attached to the support and moved from an unlatched position to a latched position by a striker when the deck lid is closed. The fork bolt is held in the latched position by a moveable detent lever that is moved to a release position to release the fork bolt so that the deck lid can be opened. The closure latch includes a detent lock-out that holds the detent lever in the release position until the deck lid is opened once the fork bolt is released. The detent lock out includes a striker position lever that is moved to an engaged position by the striker being retained by the fork bolt and a detent pawl that holds the detent lever in the released position once the detent lever is released.

  • Publication number: 20020027365
    Abstract: An improved lift gate power cincher uses and electromagnetic pulling action, instead of a mechanical hooking action, to pull the lift gate closed, thereby eliminating the need for a manual over ride in the event of electrical failure. An electromagnet fixed to the gate power retracts and re extends, activated as it retracts, and de activated as it re extends to a cinch ready position. The magnet pulls face to face on a vehicle mounted steel plate, and, therefore, simply releases in the event that power fails. The plate is also spring loaded to compress and yield if the power fails with the magnet not fully retracted, so that the gate may still be shut.

  • Patent number: 6309005
    Abstract: A hard tonneau cover is pivotally attached to each side wall of a truck cargo box having a tail gate by a hinge assembly. Each hinge assembly includes a four bar linkage and a drive mechanism. The four bar linkage consists of a tonneau bracket that is secured to the tonneau cover, a mounting bracket, a hinge link that is pivotally attached to the tonneau bracket at one end by a first pivot and to the mounting bracket at an opposite end by a second pivot, and a control link that is pivotally attached to the tonneau bracket at one end by a third pivot and to the mounting bracket at an opposite end by a fourth pivot. The drive mechanism has a pivot arm that is pivotally attached to the mounting bracket by a fifth pivot, and a drive arm that is pivotally attached to the pivot arm by a sixth pivot and pivotally attached to the tonneau bracket by a seventh pivot so that the tonneau cover and bracket are moved between a closed position and an open position by rotation of the pivot arm.
