  • Cinching door latch with planetary release mechanism
    Patent number: 6550825
    Abstract: A cinching door latch has a fork bolt that pivots between a primary latched position and an unlatched position. A detent lever pivots between a an engaged position and a disengaged position holds the fork bolt in the primary latched position when in the engaged position and releases the fork bolt for movement to the unlatched position when in the disengaged position. A transfer lever pivots between a lock position and an unlock position is operatively connected to the detent lever for pivoting the detent lever to the disengaged position. A cinching mechanism assures that the fork bolt is pivoted to the primary latched position when the door is closed. The cinching mechanism has a cinching gear drivingly connected to the fork bolt, a power driven planetary gear set for driving the cinching gear, and a one-way device.
