First Claim
Patent Images
1. A motor-vehicle door latch comprising:
- a housing;
latch parts in the housing operable to unlock a vehicle door;
an actuating element;
means in the housing including a linkage engageable between the actuating element and the latch parts and 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 and operable to shift the linkage between its coupled and decoupled positions;
drive means including a drive-motor for operating the blocking element; and
a quick-unlock element pivoted on the blocking element, coupled to the linkage, and operable by the drive means to unlock the vehicle door directly on operation of the drive means.

Abstract
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.

9. A motor-vehicle door latch comprising:
-
a housing; latch parts in the housing operable to unlock a vehicle door; an actuating element; means in the housing including a linkage engageable between the actuating element and the latch parts and 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, formed with a hole, and operable to shift the linkage between its coupled and decoupled positions; drive means including a drive motor for operating the blocking element; a quick-unlock element pivotal in two directions by the drive means relative to the blocking element; a pin passing through the quick-unlock element and the hole of the blocking element and coupling together the blocking element and the quick-unlock element; a transmission lever formed with a hole into which the pin also engages, whereby the blocking element is pivotal on the transmission lever; and spring means urging the linkage into the coupled position. - View Dependent Claims (10)
