Abstract

A method for the actuation of an actuating device and to an actuating device with at least one lock, in particular a lock for a front bonnet of a motor vehicle, comprising a rotary latch, wherein the rotary latch can be brought by means of a lock holder into a locked position, with an actuating element connected to the lock, wherein, after a first actuation of the actuating element, the front bonnet can be brought from a locked position into a supported position and wherein, after at least one further actuation of the actuating element, the front bonnet can be brought into a release position, and with an actuation transmission means, in particular a Bowden cable, between the actuating element and the lock, wherein a means for disabling the actuating device is provided, with the result that an actuation of the lock by means of the actuating element can be suppressed.

First claim

The invention claimed is:

1. An actuating device for a lock for a front bonnet of a motor vehicle, the actuating device comprising:
a lock holder,
a rotary latch, wherein the rotary latch is brought by the lock holder into a locked position of the rotary latch,
an actuating element connected to the rotary latch, wherein after a first actuation of the actuating element the front bonnet is brought from a locked position of the bonnet that corresponds to the locked position of the rotary latch into a supported position and wherein after at least one further actuation of the actuating element the front bonnet is brought into a release position,
an actuation transmission between the actuating element and the rotary latch,
a means for disabling the actuating device, with the result that actuation of the rotary latch by the actuating element is suppressible, and
a control configured to detect a speed of the motor vehicle, wherein the means for disabling is controlled based on the speed detected by the control,
wherein the means for disabling acts directly on the actuation transmission.

2. The actuating device according to claim 1 , wherein the means for disabling is a component of the actuating element and/or the rotary latch.

3. The actuating device according to claim 1 , wherein the actuation transmission is blocked by means of the means for disabling.

4. The actuating device according to claim 1 , wherein the actuating element is disengaged by the means for disabling.

5. The actuating device according to claim 1 , wherein the means for disabling is operated electrically.

6. The actuating device according to claim 1 further comprising a switch configured to query a position of the means for disabling.

7. The actuating device according to claim 1 , wherein at least two rotary latches are provided for and the actuation transmission includes a switch and the means for disabling acts directly on the switch.

8. A method for controlling the actuating device according to claim 1 , the method comprising:
providing the first actuation of the actuating element to bring the front bonnet from the locked position of the front bonnet into the supported position;
providing the at least one further actuation of the actuating element to bring the front bonnet from the supported position into the release position, wherein actuation is executed by the actuation transmission arranged between the rotary latch and the actuating element, and
disabling the actuating device by the means for disabling.

9. An actuating device for a lock for a front bonnet of a motor vehicle, the actuating device comprising:
a lock holder,
a rotary latch, wherein the rotary latch is brought by the lock holder into a locked position of the rotary latch,
an actuating element connected to the rotary latch, wherein after a first actuation of the actuating element the front bonnet is brought from a locked position of the front bonnet that corresponds to the locked position of the rotary latch into a supported position and wherein after at least one further actuation of the actuating element the front bonnet is brought into a release position,
an actuation transmission between the actuating element and the rotary latch,
a means for disabling the actuating device, with the result that actuation of the rotary latch by the actuating element is suppressible, and
a switch configured to query a position of the means for disabling.

10. An actuating device for a lock for a front bonnet of a motor vehicle, the actuating device comprising:
a lock holder,
a rotary latch, wherein the rotary latch is brought by the lock holder into a locked position of the rotary latch,
an actuating element connected to the rotary latch, wherein after a first actuation of the actuating element the front bonnet is brought from a locked position of the front bonnet that corresponds to the locked position of the rotary latch into a supported position and wherein after at least one further actuation of the actuating element the front bonnet is brought into a release position,
an actuation transmission between the actuating element and the rotary latch,
a means for disabling the actuating device, with the result that actuation of the rotary latch by the actuating element is suppressible, and
wherein at least two locks are provided for and the actuation transmission includes a switch and the means for disabling acts directly on the switch.
