  • Patent number: 6098490
    Abstract: A trunk lid has an externally operated key lock cylinder that operates a latch mechanism inside the trunk by a cable assembly. The key lock cylinder is connected to the cable assembly by a universal actuator assembly including a housing having a ferrule for attachment to a sheath of the cable assembly. The universal actuator assembly further includes an attachment sleeve that is attached to the key lock cylinder in a predetermined angular orientation. The attachment sleeve has one end disposed in the chamber of the housing, with the one end having a plurality of radial teeth that engage radial lugs in the housing to index the sleeve with respect to the housing in a selected angular orientation to reduce the length of the cable assembly that is required. A rotor rotatably disposed in the housing has a central drive aperture for being driven by the key lock cylinder and an eccentric connector aperture for driving the cable assembly.

  • Patent number: 5909918
    Abstract: A deck lid may be released via rotation of a latch release shaft. A pinion gear is operably connected with the release shaft for rotating the release shaft. An electric motor has a gear meshing with the pinion gear and is energizable to rotate the pinion gear. An electrical switch is located inside the vehicle for energizing the electric motor. According to the invention, a blocking member is movably mounted on the latch and movable between a normal disengaged position, permitting rotation of the pinion gear by the motor, and a blocking position in which the blocking member engages the pinion gear to block rotation thereof by the electric motor. In a preferred embodiment, the blocking member is slidably mounted on the latch and the pinion gear has a toothed periphery with a cutout into which the blocking member is slid to block rotation of the pinion gear, thereby causing the motor to stall.
