Abstract

The object of the invention is a reversible activation unit for the alternate impingement of two separate motor vehicle functional elements (1, 2), in particular two motor vehicle door latches (1, 2). The activation unit possesses a single motor (3, 4) and two connecting elements (8, 10). The motor (3, 4) impinges either the distanced first functional element (1) via the connecting element (8) or the distanced second functional element (2) via the second connecting element (10) dependent on its working direction. According to the invention, the first connecting element (8) is connected to a first lever (7) and the second connecting element (10) to a second lever (9). The respective lever (7, 9) is impinged dependent on the working direction of the motor (3, 4) which preferably works in a linear manner. Furthermore, the two levers (7, 9) are connected via an interposed spring (15).

First claim

The invention claimed is:

1. A reversible activation unit for the alternate impingement of separate first and second motor vehicle functional elements, the reversible activation unit comprising:
a single motor having a motor connecting element that is movable in a linear manner between a neutral position and first and second opposing directions;
discrete first and second connecting elements;
discrete first and second levers, wherein the first connecting element operatively connects the first lever to the first motor vehicle functional element, and the second connecting element operatively connects the second lever to the second motor vehicle functional element, and
a spring interposed between the first and second levers for biasing each lever to the neutral position,
wherein when the motor moves the motor connecting element in the first direction from the neutral position, the motor connecting element contacts the first lever to move the first lever, independently from the second lever, to operate the first motor vehicle functional element via the first connecting element, and
wherein when the motor moves the motor connecting element in the second direction from the neutral position, the motor connecting element contacts the second lever to move the second lever, independently from the first lever, to operate the second motor vehicle functional element via the second connecting element.

2. The reversible activation unit according to claim 1 , wherein the first and second levers are formed as pivoting levers rotatable about a common axis.

3. The reversible activation unit according to claim 2 , wherein the first and second levers are formed as two-armed levers with a connecting arm for the connecting element and a stop arm.

4. The reversible activation unit according to claim 3 , wherein the connecting arm and the stop arm are opposite one another with regard to the common axis.

5. The reversible activation unit according to claim 3 , wherein the connecting element includes a hook that engages the stop arm.

6. The reversible activation unit according to claim 5 , wherein the connecting element either impinges the first lever or the second lever in a pushing or pulling manner.

7. The reversible activation unit according to claim 5 , wherein the connecting element includes an engagement opening for an adjusting lever that is a component of the motor.

8. The reversible activation unit according to claim 1 , wherein the spring is a two-armed spring with two arms connected to a wound connecting section.

9. The reversible activation unit according to claim 8 , wherein a first arm of the spring engages into a first recess of the first lever and a second arm of the spring is arranged in a second recess of the second lever.

10. The reversible activation unit according to claim 1 , wherein one of the first lever and the second lever which is not impinged is configured as a stop for the other impinged lever of the first lever and the second lever.

11. The reversible activation unit according to claim 1 , wherein the first lever and the second lever at least partially overlap.

12. The reversible activation unit according to claim 1 , wherein the first and second motor vehicle functional elements are latches.
