US Patent 7399010 Power-actuated motor-vehicle door latch with quick unlock

A motor-vehicle door latch has a housing, latch parts in the housing operable to unlock a vehicle door, and an actuating element. A linkage engageable between the actuating element and the latch parts is shiftable between a coupled position for operation of the latch parts by the actuating element and a decoupled position operatively disconnecting the actuating element from the latch parts. A blocking element connected to the linkage is operable to shift the linkage between its coupled and decoupled positions. A drive motor operates the blocking element, and a quick-unlock element pivoted on the blocking element is operable by the drive.
