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 device for an actuator ( 2 ) 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 ( 2 ) integral with the housing ( 4 ), characterized in that 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 ( 2 ) 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 an exterior of the housing ( 4 ), wherein the fastening means further includes a stop device ( 462 , 23 ) configured to block rotation of the actuator ( 2 ) in relation to the housing ( 4 ) or the support ( 6 ) in a stop position, wherein the stop device includes a latching tab ( 23 ) arranged on the actuator ( 2 ) and a holding mechanism ( 462 ) arranged on the connecting surface ( 68 ) of the support ( 6 ), the tab being designed to be fastened to the holding mechanism ( 462 ) by clipping on, when the actuator ( 2 ) reaches the stop position, and wherein the holding mechanism ( 462 ) comprises a guide element ( 460 ) and holding elements ( 462 ).

2. The device of claim 1 , characterized in that the connecting flanges ( 20 , 40 ) are shaped so that the actuator ( 2 ) is connected to the support ( 6 ) by a translational movement, in the direction of the drive shaft, towards the interior of the housing, followed by a rotational movement, until the 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 of claim 1 , characterized in that the connecting flanges ( 20 , 40 ) have mating helical connecting shapes on at least a portion of their wall, and in that the male connecting flange shapes ( 20 ) comprise discontinuous helical grooves ( 200 ).

5. The device of claim 1 , wherein the guide element being shaped so as to bring the latching tab ( 23 ) substantially opposite the holding element ( 462 ) during the rotating movement of the actuator ( 2 ), and the holding elements ( 462 ) being shaped so as to connect by clipping together with the latching tab ( 23 ), when the actuator ( 2 ) reaches its stop position.

6. The device of claim 5 , characterized in that the latching tab ( 23 ) comprises an elastic portion, and in that the guide element ( 460 ) is shaped so as to exert increasing stress on the latching tab ( 23 ) during the rotating movement of the actuator ( 2 ), the elastic portion of the latching tab relaxing when the tab arrives substantially opposite the holding elements ( 462 ).

7. The device of claim 1 , characterized in that the latching tab ( 23 ) extends in an overall plane that is substantially perpendicular to the connecting surface ( 28 ) on which it is arranged.

8. The device of claim 1 , characterized in that the stop device includes a holding stud ( 463 ) arranged on the support ( 6 ), and in that the actuator ( 2 ) is designed to be screwed onto the holding stud, after assembly of the actuator ( 2 ) and the housing ( 4 ).
