Abstract

The invention relates to a closing device, in particular for a cover of a motor vehicle, having a rotary latch which interacts with a cover-side locking clamp (10) and which is held securely in its closed position by means of a pawl, and with a catch hook (20) which can be caused to engage the catch element (42) after transfer of the pawl into the open position and by which the cover is to be kept in the holding position, and the catch hook (20) can be transferred out of the holding position into the open position in which the cover is to be completely opened, the rotary latch and the catch hook (20) being made as separate parts, and the pawl of the rotary latch and the catch hook (20) is to be actuated in a sequence via a common remote actuation element (Bowden cable 24) after one another.

Claims

1. Closing device for a cover of a motor vehicle, the device comprising a rotary latch which interacts with a cover-side locking clamp and is held securely in its closed position by means of a pawl a catch hook which can be caused to engage the catch element after transfer of the pawl into the open position and by which the cover is to be kept in the holding position, and the catch hook is to be transferred out of the holding position into the open position in which the cover is to be completely opened, wherein the rotary latch and the catch hook are made as separate parts, and the pawl of the rotary latch and the catch hook is to be actuated in a sequence via a common remote actuation element after one another.

2. The closing device according to claim 1, wherein the remote actuation element is a Bowden cable, the cord is connected to the pawl and the jacket being connected to the catch hook.

3. The closing device according to claim 2, wherein the jacket is supported on the catch hook lever of the catch hook via which the catch hook is to be transferred out of the holding position into the open position.

4. The closing device according to one of claim 3, wherein the actuating force of the pawl is designed to be less than the actuating force of the catch hook lever and of the catch hook.

5. The closing device according to claim 2, wherein the pawl after actuation with the cord (36) reaches an end stop (56), after which the jacket for actuating the catch hook is to be moved in the direction of the pawl relative to the cord.

6. The closing device according to claim 1, wherein actuation of the catch hook is to be stopped by a blocking means which is to be switched on the basis of the driving speed of the vehicle.

7. The closing device according to claim 5, wherein the movement of the jacket relative to the cord is to be stopped by a blocking means .

8. The closing device according to claim 1, wherein the remote actuation element for emergency release of the closing device is located in the front trunk of the motor vehicle, and the pawl of the rotary latch is to be transferred by another remote actuation means in the interior of the vehicle into its open position.

9. The closing device according to claim 1 wherein the catch hook is to be transferred manually out of the holding position into the open position independently of the remote actuation element.

10. The closing device according to claim 1, wherein the pawl of the rotary latch and the catch hook travel automatically back into their closed position or holding position after actuation by means of the remote actuation element.

11. A mechanism for closing a cover of a motor vehicle, the mechanism comprising:

a rotary latch;

a locking clamp, positioned to interact with a cover-side locking clamp and held securely in its closed position by a pawl and a catch, which can be caused to engage a catch element after transfer of the pawl into its open position; and

by which the cover is to be kept in the holding position;

wherein the catch hook is transferred out of the holding position into the open position when the cover is to be completely opened,

that the rotary latch and the catch hook are made as separate parts; and

the pawl of the rotary latch and the catch hook are actuated in a sequence via a common remote actuation element after one another.

12. A method for closing a cover of a motor vehicle, the method comprising:

moving a rotary latch, which interacts with a cover-side locking clamp and a pawl from a closed position to an open position;

holding the cover in its open position, comprising transferring a catch hook out of a holding position to its open position; and

actuating, in sequence, the rotary latch and catch hook via a common remote actuation element.
