US Patent 7080861 Anti-panic mechanism of vehicle door latch device

An anti-panic mechanism for a vehicle door latch device comprises a movable member provided between to an open link and a lock lever, and an anti-panic spring elastically connecting the lock lever with the movable member. When an unlocking operation by an inside lock button is not completed normally due to a first opening operation of an open handle, the movable member is displaced by a spring force of the anti-panic spring to move the open link to an engageable position after the open lever is returned to an initial position. The movable member and lock lever are coaxially pivoted by a single common shaft.
