Device for sealing the front-end air intake of a motor vehicle and method for manufacturing same

1. A sealing device for the front-end air inlet of a motor vehicle, comprising:

a supporting frame comprising two longitudinal crossmembers parallel to one another and two side posts perpendicular to said longitudinal crossmembers and connecting said longitudinal crossmembers;

at least one flap mounted pivotably about a pivot axis between a sealing position and an open position, said at least one flap being installed within the supporting frame;

at least one electric control element that controls the positioning of the flap or flaps and is connected to the electric system of the motor vehicle by at least one power supply cable,

wherein the supporting frame comprises at least one snap-fit attachment device to which the power supply cable or cables are attached, said snap-fit attachment device being integral with said supporting frame,

wherein the at least one snap-fit attachment device is arranged on the rear face of at least one of said side posts of the supporting frame.

2. The sealing device as claimed in claim 1 , wherein the at least one snap-fit attachment device is arranged on at least one of said longitudinal crossmembers of the supporting frame.

3. The sealing device as claimed in claim 2 , wherein the at least one snap-fit attachment device is arranged on the lower longitudinal crossmember.

4. The sealing device as claimed in claim 1 , wherein the at least one snap-fit attachment device comprises two elastic tabs positioned opposite one another and the two elastic tabs are configured to house the power supply cable or cables, the ends of said elastic tabs being separated by a distance smaller than the diameter of the power supply cable or cables so as to partially cover said power supply cable or cables.

5. The sealing device as claimed in claim 1 , wherein the at least one snap-fit attachment device comprises:

an elastic tab, and

a rigid wall positioned opposite said elastic tab,

said elastic tab comprising, at the end of same, a hook, said hook extending between the elastic tab and said rigid wall.

6. The sealing device as claimed in claim 5 , wherein said supporting frame comprises at least one groove into which the power supply cable or cables pass.

7. The sealing device as claimed in claim 6 , wherein one of the walls of the groove comprises at least one recess inside which the elastic tab is positioned, the rigid wall positioned opposite said elastic tab being the opposing wall of said groove.

8. The sealing device as claimed in claim 1 , wherein the power supply cable or cables are inserted into the at least one snap-fit attachment device and connected to the at least one control element.

9. The sealing device as claimed in claim 8 , wherein the power supply cable or cables are deformed when inserted into the at least one snap-fit attachment device.

10. A method for manufacturing a sealing device for the front-end air inlet of a motor vehicle, the sealing device comprising:

a supporting frame comprising two longitudinal crossmembers parallel to one another and two side posts perpendicular to said longitudinal crossmembers and connecting said longitudinal crossmembers,

at least one flap mounted pivotably about a pivot axis between a sealing position and an open position, said at least one flap being installed within the supporting frame, and

at least one electric control element that controls the positioning of the flap or flaps and is suitable for being connected to the electric system of the motor vehicle by at least one power supply cable,

said manufacturing method comprising:

manufacturing the supporting frame, said supporting frame comprising at least one snap-fit attachment device for attaching the power supply cable or cables, said attachment device being integral with said supporting frame;

installing the flap or flaps and the control element or elements on the supporting frame; and

connecting the power supply cable or cables to the control elements and attaching said power supply cable or cables to said snap-fit attachment devices.

11. The manufacturing method as claimed in claim 10 , wherein the supporting frame is produced from plastic material and the step of manufacturing the supporting frame is a molding step.

12. A sealing device for the front-end air inlet of a motor vehicle, comprising:

a supporting frame comprising two longitudinal crossmembers parallel to one another and two side posts perpendicular to said longitudinal crossmembers and connecting said longitudinal crossmembers;

at least one flap mounted pivotably about a pivot axis between a sealing position and an open position, said at least one flap being installed within the supporting frame;

at least one electric control element that controls the positioning of the flap or flaps and is connected to the electric system of the motor vehicle by at least one power supply cable,

wherein the supporting frame comprises at least one snap-fit attachment device to which the power supply cable or cables are attached, said snap-fit attachment device being integral with said supporting frame,

wherein the at least one snap-fit attachment device comprises two elastic tabs positioned opposite one another and the two elastic tabs are configured to house the power supply cable or cables, the ends of said elastic tabs being separated by a distance smaller than the diameter of the power supply cable or cables so as to partially cover said power supply cable or cables.
