  • Publication number: 20090230700
    Abstract: A vehicle door latch system configured to temporarily prevent door latch mechanisms from unlatching during a predetermined event is provided. The vehicle door latch system includes a forkbolt pivotally mounted to a housing portion of the vehicle door latch. The forkbolt is capable of moving between a latching position and an unlatching position. The door latch system also includes a block out mechanism configured for movement between a blocking position and an unblocking position. The block out mechanism is configured to prevent the forkbolt from moving from the latching position to the unlatching position when the block out mechanism is in the blocking position. A biasing member biases the block out mechanism into the unblocking position.

  • Publication number: 20070193267
    Abstract: An electrical actuator is characterized by applying electrical current directly to a smart wire to produce an output motion. The smart wire is looped around a drive member that is engaged with a moveable member, fixed at both ends to electrical terminals, and contains one or more coils between the electrical terminals and the drive member. Smart wire coils can either be wrapped around a reel in a helical fashion or moveably disposed in flexible tubing for support. Direct electrical current applied to the smart wire results in heating and contraction of the wire. Subsequent removal of electrical current allows the wire to cool and return to its original size and shape. The force and stroke of the electrical actuator can be tailored to meet specific requirements by changing wire diameter and length.
