Abstract

The invention relates to a closing system for a door or a flap of a motor vehicle and comprises a lock, a door handle affixable to the door and fitted with an external grip element with a centralized locking motor linked to a control unit and operationally connected to the lock, whereby the closing system can be moved into a secured and into a disengaged state, and also comprises an opening motor acting as an opening accessory and/or a closing motor acting as a closing accessory for the lock.

The invention provides that the door handle be associated with a handle support which is configured internally on the side away from the grip element and which affixes the door handle to the door, said opening motor and/or the closing motor as well as the centralized locking motor being mounted on the handle support, where said opening motor and/or the closing motor as well as the centralized locking motor are connected directly, or indirectly by means of at least one force transmitting element, to the lock 3.

Claims

1. A closing system for a motor vehicle door or a flap, comprising:

a door handle affixed to the door and including an external grip element,

a centralized locking motor connected to a control unit operationally connected to the lock, whereby the locking system is moved into a secured state and into a disengaged state,

and an opening motor acting as an opening accessory and/or with a closing motor acting as a closing accessory for the lock,

wherein the door handle a handle support configured internally on the side which is away from the grip element for the purpose of affixing the door handle to the door,

wherein the opening motor and/or the closing motor as well as the centralized locking motor are mounted on the handle support,

wherein the opening motor and/or the closing motor as well as the centralized motor are directly connected, or indirectly connected by means of at least one force transmitting element, to the lock.

2. The closing system as claimed in claim 1, wherein the opening motor and the closing motor are integrated into one motor unit.

3. The closing system as claimed in claim 1, wherein the centralized locking motor and/or the closing motor and/or the opening motor are received in a common housing.

4. The closing system as claimed in claim 1, wherein the force transmitting element is a bowden cable.

5. The closing system as claimed in claim 1, wherein the handle support is made of plastic.

6. The closing system as claimed in claim 1, wherein the lock includes a rotational catch and a pawl, the pawl acting on the rotational catch receiving a securing element affixed to the automobile body when the door is closed.

7. The closing system as claimed in claim 1, wherein the control unit is connected to the closing motor and/or to the opening motor.

8. The closing system as claimed in claim 1, wherein that the door handle comprises a sensor allowing keylessly actuating the closing system, said sensor being designed as a contact and/or proximity sensor and connected to the control unit.

9. The closing system as claimed in claim 8, wherein the actuation element is a capacitive sensor and/or a Hall effect generator and/or a piezoelectric sensor.

10. The closing system as claimed in claim 1, wherein the door handle is designed as a collapsing handle, or a pull handle or a revolver handle.

11. The closing system as claimed in claim 10, wherein the grip element is manually pivotable about a pivot pin, the door handle includes an inside connecting element which is mounted by its free end to the pivot pin.

12. The closing system as claimed in claim 1, wherein the centralized locking motor is connected to a coupling which by means of said motor can be moved into a coupled and into a decoupled state and which is operationally connected through an adjustment element to the lock, said locking system being secured when in said decoupled state and being disengaged when in said coupled state.

13. The closing system as claimed in claim 1, wherein the door handle comprises an emergency cylinder mounted on the handle support.

14. The closing system as claimed in claim 1, wherein the coupling and/or the control unit are mounted on the handle support, in particular in the housing.

15. The closing system as claimed in claim 1, wherein that the grip element of the door handle is designed as a fixed grip element mounted on the door.

16. The closing system as claimed in claim 1, wherein that the closing motor and the opening motor are configured in the zone of the pivot axis, the junction element being configured between the closing motor and the opening motor.

17. The closing system as claimed in claim 1, wherein the centralized locking motor is situated in the region of the emergency cylinder.

18. A motor vehicle fitted with a closing system as claimed in claim 1.

19. The motor vehicle of claim 2, wherein the opening motor and the closing motor are integrated into one motor unit.
