Abstract

In order to improve the release movement of a closure bracket assembly for retaining or raising a pivotable front flap of a motor vehicle from a normal position into a protection position, a closure bracket having a closure bolt and a closure bracket upper part is provided. The closure bolt is secured in a lock in the normal position and in the protection position. A front flap securing device can be secured on the front flap. A pivot shaft is arranged on the front flap securing device and about which the front flap securing device is pivotally mounted for raising purposes. A closure bracket holder is provided on which the closure bracket is held. The pivot shaft is arranged on the closure bracket holder and the closure bolt can be pivoted in the lock during raising.

First claim

What is claimed is:

1. A closure bracket assembly for retaining or raising a pivotable engine hood of a motor vehicle from a normal position into a protection position, comprising:
a closure bracket having a closure bolt and a closure bracket upper part, wherein the closure bolt is directly secured in a front engine hood lock located in a front area of the engine hood in the normal position and in the protection position;
an engine hood fastening device that is securable on the engine hood;
a pivot shaft which is arranged on the engine hood fastening device and about which the engine hood fastening device is pivotably mounted for raising purposes; and
a closure bracket holder on which the closure bracket is held, wherein
the pivot shaft is arranged on the closure bracket holder, and
the closure bolt is pivotable in the front engine hood lock during raising.

2. The closure bracket assembly as claimed in claim 1 , wherein
a first antirotation device, cooperating with a first releasing device, is arranged on the engine hood fastening device, which secures the engine hood fastening device in the normal position and releases the engine hood fastening device to assume the protection position.

3. The closure bracket assembly as claimed in claim 2 , wherein
the first releasing device and the first antirotation device are joined together releasably by force locking, form fit and/or frictional locking.

4. The closure bracket assembly as claimed in claim 2 ,
the first releasing device is a blocking pawl which in the normal position lies against the first antirotation device, designed as a spring.

5. The closure bracket assembly as claimed in claim 3 ,
the first releasing device is a blocking pawl which in the normal position lies against the first antirotation device, designed as a spring.

6. The closure bracket assembly as claimed in claim 1 , wherein
a second antirotation device, cooperating with a second releasing device, is arranged on the engine hood fastening device, which secures the engine hood fastening device in the normal position and releases the engine hood fastening device to assume the protection position.

7. The closure bracket assembly as claimed in claim 2 , wherein
a second antirotation device, cooperating with a second releasing device, is arranged on the engine hood fastening device, which secures the engine hood fastening device in the normal position and releases the engine hood fastening device to assume the protection position.

8. The closure bracket assembly as claimed in claim 6 , wherein
the second releasing device and the second antirotation device are joined together releasably by force locking, form fit and/or frictional locking.

9. The closure bracket assembly as claimed in claim 7 , wherein
the second releasing device and the second antirotation device are joined together releasably by force locking, form fit and/or frictional locking.

10. The closure bracket assembly as claimed in claim 6 , wherein
the second releasing device is a spring which in the normal position engages the second antirotation device, designed as a groove.

11. The closure bracket assembly as claimed in claim 8 , wherein
the second releasing device is a spring which in the normal position engages the second antirotation device, designed as a groove.

12. The closure bracket assembly as claimed in claim 7 , wherein
the first releasing device and/or the second releasing device is activatable by an actuator.

13. The closure bracket assembly as claimed in claim 1 , wherein
the closure bracket holder is substantially congruent with the engine hood fastening device and/or is arranged in the latter in the normal position.

14. The closure bracket assembly as claimed in claim 1 , wherein
the closure bracket has at least one adjustment device.

15. A motor vehicle comprising:
an engine hood which is raisable from a normal position into a protective position by way of a rear hinge mechanism;
the front engine hood lock arranged in the front area of the engine hood; and
a closure bracket assembly as claimed in claim 1 .
