Abstract

The invention proposes a device for attaching an actuator ( 2 ) to a housing ( 4 ), in particular for an automotive vehicle, the actuator being provided for driving a movable equipment ( 41 ) disposed within the housing. The device comprises attaching means for attaching the actuator on the housing. The mounting means comprise two conjugated connection flanges ( 20, 40 ), respectively mounted on a connexion face ( 28 ) of the actuator ( 28 ) and on a connection face ( 48 ) of the housing. The connexion flanges are adapted to be assembled according to a male/female type connection at the outside of the housing.

First claim

The invention claimed is:

1. A fastening device for an actuator ( 1 ) with a housing ( 4 ), in particular for a motor vehicle, the actuator ( 2 ) being designed to drive a movable member ( 41 ) arranged inside the housing ( 4 ), the device comprising fastening means for coupling the actuator with the housing, a support ( 6 ) is placed between the actuator ( 2 ) and the housing ( 4 ), the fastening means include two mating connecting flanges ( 20 , 40 ) mounted, respectively, on a connecting surface ( 28 ) of the actuator and on a connecting surface ( 68 ) of the support ( 6 ), and in that the connecting flanges ( 20 , 40 ) are configured to be assembled via a male/female-type connection on the exterior of the housing, wherein the support ( 6 ) is U-shaped such that a cavity ( 62 ) is formed between an external face ( 48 ) of the housing ( 4 ) and the support ( 6 ) which houses at least one link mechanism ( 100 ) that is completely disposed between the external face of the housing ( 4 ) and the support ( 6 ).

2. The device as claimed in claim 1 , characterized in that the connecting flanges ( 20 , 40 ) are shaped so that the actuator is connected to the to the support ( 6 ) by a translational movement, in the direction of a drive shaft, towards the interior of the housing, followed by a rotational movement, until a predefined stop position is reached.

3. The device of claim 2 , characterized in that the connecting flanges ( 20 , 40 ) are shaped so as to produce a translational movement towards the housing ( 4 ) during the rotational movement of the actuator ( 2 ).

4. The device as claimed in claim 1 , characterized in that the connecting flanges ( 20 , 40 ) have mating helical connecting shapes on at least a portion of a wall, and in that the male connecting flange shapes ( 20 ) comprise discontinuous helical grooves ( 200 ).

5. The device of claim 1 , characterized in that the movable member ( 410 ) has a connecting bearing ( 465 ) and the actuator has a drive shaft ( 22 ), the connecting bearing being shaped so as to be connected to the drive shaft of the actuator during the fastening of the connecting flanges ( 20 , 40 ).

6. The device of claim 5 , characterized in that the drive shaft ( 220 ) of the actuator ( 2 ) and the connecting bearing ( 465 ) of the movable member ( 41 ) are coaxial in relation to the axis of the connecting flanges ( 20 , 40 ).

7. A fastening device for an actuator ( 1 ) with a housing ( 4 ), in particular for a motor vehicle, the actuator ( 2 ) being designed to drive a movable member ( 41 ) arranged inside the housing ( 4 ), the device comprising fastening means for making the actuator integral with the housing, characterized in that the fastening means include two mating connecting flanges ( 20 , 40 ) mounted on a connecting surface ( 28 ) of the actuator and coupled to en-a connecting surface ( 48 ) of the housing, and in that the connecting flanges are configured to be assembled via a male/female-type connection on an exterior of the housing wherein the device further comprises a support ( 6 ) which is U-shaped such that a cavity ( 62 ) is formed between an external face ( 48 ) of the housing ( 4 ) and the support ( 6 ) which houses at least one link mechanism ( 100 ) that is completely disposed between the external face of the housing ( 4 ) and the support ( 6 ).

8. The device of claim 7 , further including a locator ( 500 ) comprising three sub-locators ( 501 , 502 , 503 ) placed so as to form an arc of circle, the center of this arc of circle being located by an axis of rotation D of the flange ( 20 ) of the actuator ( 2 ), this arc of circle arrangement limiting the placement of the actuator ( 2 ) to a single position in relation to the housing ( 4 ) or the support ( 6 ).

9. The device of claim 1 , characterized in that the connecting flange ( 20 ) of the actuator ( 2 ) includes helical connecting shapes ( 200 ) on both an interior surface and an exterior surface of a wall of the connecting flange or on one of the interior surface or exterior surfaces of the wall of the connecting flange.

10. The device of claim 7 , characterized in that the connecting flange ( 20 ) of the actuator ( 2 ) includes helical connecting shapes ( 200 ) on both an interior surface and an exterior surface of a wall of the connecting flange or on one of the interior surface or exterior surface of the wall of the connecting flange.
