Abstract

The invention relates to a handle device for a lock unit (7) of a vehicle, comprising a handle part (10) which is movably mounted relative to a door (5) of the vehicle, a locking unit (40) for preventing unintentional opening of the door (5) caused by accelerations acting upon the handle part (10), especially accelerations such as they act upon the vehicle during a crash, the locking unit (40) being displaceable between a locking position (1) and a release position (2), and a movement of the handle part (10) being enabled in the release position (2) and a movement of the handle part (10) being disabled in the locking position (1). The invention is characterized in that an actuating unit (50) is actively connected to the locking unit (40) such that the locking unit (40) can be brought from the locking position (1) into the release position (2) when the actuating unit (50) is activated.

Claims

1. A handle device for a locking device of a vehicle, said handle device comprising:

a handle part movably mountable with respect to a door of the vehicle;

a blocking unit preventing unintentional opening of the door as a consequence of the action of accelerations acting on the handle part, the accelerations acting on the vehicle in particular in the event of an accident, wherein the blocking unit can be displaced between a locking position and a release position, wherein movement of the handle part is possible in the release position and movement of the handle part is blocked in the locking position and

an actuating unit operatively connected to the blocking unit in such a manner that the blocking unit can be brought from the locking position into the release position via activation of the actuating unit.

2. The handle device as claimed in claim 1, in which the blocking unit can be brought into the release position and locking position via a manual activation of the actuating unit.

3. The handle device as claimed in claim 1, in which the blocking unit is coupled to the handle part in such a manner that the blocking unit moves the handle part by manual activation of the actuating unit.

4. The handle device as claimed in claim 1, in which the handle part is movable between a rest position and an operating position, wherein, the handle part lies virtually flush with them outer side of the door in the rest position and, in the operating position, the handle part protrudes out of the outer side of the door in the manner of a projection, and, in the operating position, the handle part is actuable manually in order to at least one of open the door and activate the locking device in order to open the lock of the locking device.

5. The handle device as claimed in claim 1, in which the blocking unit always adopts the locking position, wherein the blocking unit is in the release position only for the movement of the handle part from the rest position into the operating position.

6. The handle device as claimed in claim 1, in which the handle part has a first operating position and a second operating position, wherein the handle part, in the second operating position, the handle part protrudes further from an outer side of the door than in the first operating position.

7. The handle device as claimed in claim 1, in which the locking device is integrated in a security system functioning without a key.

8. The handle device as claimed in preceding claim 1, in which the blocking unit has a blocking element, wherein, in the locking position of the blocking unit, the blocking element adopts a first position and engages in the handle part and, in the release position, the blocking element is in a second position and is detached from the handle part.

9. The handle device as claimed in claim 1, in which the blocking unit has a blocking element movable between a first position and a second position, wherein, in the locking position of the blocking unit, the blocking element adopts the first position and engages in the handle part, wherein, during movement of the blocking unit into the release position, the blocking element moves into the second position, and wherein the blocking element acts on the handle part in such a manner that the handle part moves from the rest position into the operating position.

10. The handle device as claimed in claim 9, including a drive connected to the blocking element the blocking element being movable between the first position and the second position, and wherein, the drive comprises the actuating unit.

11. The handle device as claimed in claim 10, characterized in that the drive moves the blocking element in a translatory manner via at least one of a pivoting and rotational movement of the actuating unit.

12. The handle device as claimed in claim 8, in which the blocking element has a first end and a second end, wherein the first end interacts with the handle part and the second end is arranged on the actuating unit.

13. The handle device as claimed in claim 1, including a handle mount arranged fixedly within the door, and a handle shell fastened to the handle mount is arranged on an opening of the door.

14. The handle device as claimed in claim 13, in which at least one of the handle shell and the handle mount forms a bearing for the handle part.

15. The handle device as claimed in claim 13, in which the actuating unit is arranged rotatably on the handle mount.

16. The handle device as claimed in claim 13, characterized in that the handle mount has at least one bearing point for the blocking unit.

17. The handle device as claimed in claim 8, in which the blocking element extends longitudinally in the direction of the vehicle (R) in the manner of a rod having a defined, curved profile.

18. The handle device as claimed in claim 1, in which the actuating unit has a sufficiently small mass that, in the event of and as a consequence of the action of accelerations acting on the actuating unit, the blocking unit remains in the locking position.

19. The handle device as claimed in claim 8, in which the blocking element has a geometrically shaped section which engages the handle part during the transfer from the first position into the second position.

20. The handle device as claimed in claim 1, in which at least one of the actuating unit and the handle part is spring-loaded.

21. A method for operating a handle device for a locking device of a vehicle, with a handle part which is mounted movably with respect to a door of the vehicle, a blocking unit for preventing unintentional opening of the door as a consequence of the action of accelerations acting on the handle part, the accelerations acting on the vehicle in particular in the event of an accident, wherein the blocking unit can be displaced between a locking position and a release position, movement of the handle part is possible in the release position and movement of the handle part is blocked in the locking position, and an actuating unit is provided, said actuating unit being operatively connected to the blocking unit, said method comprising:

activating said actuating unit to move the blocking unit from the locking position into the release position.

22. The method as claimed in claim 21, including moving the handle part via activation of the actuating unit at the same time as moving the blocking unit.

23. The method as claimed in claim 21, including moving the handle part between a rest position and an operating position, wherein, the handle part lies substantially flush with the outer side of the door in the rest position and, in the operating position, protrudes out of the outer side of the door.

24. The method as claimed in claim 23, including manually moving the handle part from a first operating position into a second operating position to open a lock of the locking device.

25. The method as claimed in claim 21, in which the locking device is integrated in a security system functioning without a key, said security system being in data communication with a mobile ID transmitter, wherein, with a conscious action of the user, in particular at the ID transmitter or at the handle device, an identification check is carried out between the ID transmitter and the security system, said method including carrying out an identification check between the ID transmitter and the security system.

26. The method as claimed in claim 25, in which, given a positive identification from the identification check, the method includes moving the handle part from the rest position into the operating position and at the same time moving the locking device from a locking state into a release state.

27. The method as claimed in claim 25, in which the identification check is started by activation of the actuating unit.
