1. A lock suitable for use in a motor vehicle door, comprising:
- a rotary latch, a locking wedge, a pawl, a setting device, and a transmission device;
wherein said rotary latch cooperates with said locking wedge to be locked in a locking position and held in said locking position by said pawl;
wherein said setting device includes motorized means, responsive to operation of a manipulator along a first path of travel, for driving said pawl to an opening position which frees said latch from said locking position, said manipulator comprising a handle;
said transmission device interconnects said manipulator with said pawl, and includes means responsive to operation of said manipulator along a second path of travel, longer than said first path of travel, for driving said pawl to said opening position; and
said setting device is coupled to said pawl by a mechanical connection permitting said transmission device to displace said pawl to said opening position independently of a position of said setting device.

Abstract
A lock suitable for use in a motor vehicle door has a rotary latch, a locking wedge, a pawl, a setting device, and a transmission device wherein the rotary latch cooperates with the locking wedge to be locked in a locking position by the pawl. Upon actuation of a manipulator, the setting device brings the pawl electrically at least into one opening position. The transmission device brings the pawl into its opening position by actuation of the manipulator over a displacement range which is greater than a displacement range of an electric unlocking.

1. A lock suitable for use in a motor vehicle door, comprising:
-
a rotary latch, a locking wedge, a pawl, a setting device, and a transmission device;
wherein said rotary latch cooperates with said locking wedge to be locked in a locking position and held in said locking position by said pawl;
wherein said setting device includes motorized means, responsive to operation of a manipulator along a first path of travel, for driving said pawl to an opening position which frees said latch from said locking position, said manipulator comprising a handle;
said transmission device interconnects said manipulator with said pawl, and includes means responsive to operation of said manipulator along a second path of travel, longer than said first path of travel, for driving said pawl to said opening position; and
said setting device is coupled to said pawl by a mechanical connection permitting said transmission device to displace said pawl to said opening position independently of a position of said setting device. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
a control device having a actuation-detection device operative in response to a movement of the manipulator, and a signal line interconnecting the manipulator and the actuation-detection device to the setting device;
wherein said pawl has an arm, and said transmission device has at least a first swingable lever extending into a region of the pawl; and
upon actuation of the manipulator and upon said actuation-detection device being placed in active position by the control device, said setting device acts on said pawl to bring said pawl into its opening position; and
a projection of said lever of said transmission device is brought into operative connection with said arm of said pawl upon actuation of the manipulator.
-
-
3. A lock according to claim 2, further comprising
a lock cylinder, and a second lever which is a linearly movable lever having a projection which is arranged in a region of said pawl; wherein said second lever is brought into operative connection with said arm of said pawl upon actuation of said lock cylinder.
-
4. A lock according to claim 3, further comprising a second setting device coupled directly, or with the interposition of transmission elements, to said transmission device.
-
5. A lock according to claim 4, wherein said first lever of said transmission device is operatively coupled to said second setting device.
-
6. A lock according to claim 5, wherein said first lever is an inner lever of said lock.
-
7. A lock according to claim 4, wherein
said second setting device is an electromotive, an electromagnetic or a clapper relay, or a pneumatic setting device. -
8. A lock according to claim 3, wherein
at least one of said first and said second levers is spring-loaded in a direction of swing. -
9. A lock according to claim 3, wherein
at least one of said first and said second levers is connected by a Bowden cable to said manipulator and is actuatable independently of the other by said manipulator. -
10. A lock according to claim 9, wherein said manipulator is an inside or outside door handle.
-
11. A lock according to claim 3, wherein
at least one of said first and said second levers is connected by a Bowden cable to said lock cylinder and is actuatable independently of the other by said manipulator. -
12. A lock according to claim 3, wherein
said lock further comprises two Bowden cables connecting with a slide-block pusher, said first lever of said transmission device terminates in said slide-block pusher; - and
said pusher is slidably displaced by a core of either one of said Bowden cables.
- and
-
13. A lock according to claim 12, wherein
said pusher comprises two parts, said parts being connected with respective ones of the Bowden cables. -
14. A lock according to claim 3, further comprising an inner safety button;
- and
wherein said pawl has a lever arm which is connected by connecting elements to said inner safety button.
- and
-
15. A lock according to claim 14, further comprising
connecting elements for a direct or indirect movement of said pawl into its open position, said connecting elements being arranged between said manipulator and said pawl. -
16. A lock according to claim 15, wherein movement of said pawl is accomplished via said second lever.
-
17. A lock according to claim 3, wherein
said setting device has moving means which, in a third position of said setting device, moves a projection of at least one of said first and said second levers out of the region of said pawl for inhibiting a bringing of said pawl into its open position by an actuation of the manipulator. -
18. A lock according to claim 17, wherein
the third position of said setting device, at least when energy is present in said setting device, produces an anti-theft position of said lock in which said pawl cannot be brought into the open position either electromechanically or via said transmission device. -
19. A lock according to claim 3, wherein
at least one of said first and said second levers is spring-loaded in a direction of actuation. -
20. A lock according to claim 3, wherein
at least one of said first and said second levers is spring-loaded in a direction of swing and of actuation.
