Abstract

The present invention relates to a device ( 1 ) for sealing a motor vehicle front face air intake, comprising:
a supporting frame ( 5 ) in which is installed at least one set of flaps ( 3 ) pivoting about pivot pins (A), at least one control element ( 13 ) configured to control the positioning of the flaps ( 3 ), the supporting frame ( 5 ) including at least one row of bearings ( 51 ) receiving the pivot pins (A) arranged on a side pillar ( 5 b ), the sealing device ( 1 ) including at least one locking element ( 60 ) covering a row of bearings ( 51 ), said locking element ( 60 ) comprising a body and at least one connection member ( 61 ) including a base connecting it to said body of the locking element ( 60 ) and a head wider than said base, said side pillar ( 5 b ) including at least one slot ( 52 ) opening onto an outer side of said side pillar ( 5 b ) and preferably having a shape complementing said at least one connection member ( 61 ), said at least one connection member ( 61 ) being inserted into the at least one slot ( 52 ).

First claim

The invention claimed is:

1. A device for sealing a motor vehicle front face air intake, comprising:
a supporting frame in which is installed at least one set of flaps pivoting about pivot pins between a closed position and an open position;
at least one control element configured to control the positioning of the flaps,
the supporting frame including at least one row of bearings receiving the pivot pins of the flaps arranged on a side pillar,
wherein the sealing device includes at least one locking element covering one row of bearings and holding the pivot pins of the flaps in said bearings,
said locking element comprising a body and at least one connection member including a base connecting the connection member to said body of the locking element and a head wider than said base,
said side pillar including, on the face thereof comprising the at least one row of bearings, at least one slot opening onto a lateral side of said side pillar having a shape complementing said at least one connection member, said at least one connection member being inserted into the at least one slot from the lateral side.

2. The sealing device as claimed in claim 1 , in which the connection member projects from the body of the locking element.

3. The sealing device as claimed in claim 1 , wherein the at least one connection member is generally T-shaped.

4. The sealing device as claimed in claim 1 , characterized in that the locking element is secured to the supporting frame comprising the row of bearings by a snap fitting so as to retain the at least one connection member in the at least one slot.

5. The sealing device as claimed in claim 4 , wherein the snap fitting includes a flexible tab a first end of which includes an end piece projecting towards the outside of the supporting frame and a second end of which is connected to said supporting frame, said end piece being intended for being inserted into an opening made in the locking element.

6. The sealing device as claimed in claim 4 , wherein the snap fitting includes a flexible tab a first end of which includes an end piece projecting towards the outside of the locking element and a second end of which is connected to the locking element, said end piece being intended for being inserted into an opening made in the supporting frame.

7. The sealing device as claimed in claim 1 , wherein the flaps include flanges at the ends thereof and the locking element includes hemispherical cheeks covering the flanges of said flaps.

8. The sealing device as claimed in claim 1 , wherein the at least one row of bearings is made on the front face of the supporting frame.

9. A method for manufacturing a sealing device, the sealing device comprising a supporting frame in which is installed at least one set of flaps pivoting about pivot pins between a closed position and an open position, and at least one control element configured to control the positioning of the flaps, the supporting frame including at least one row of bearings receiving the pivot pins of the flaps arranged on a side pillar, the sealing device including at least one locking element covering one row of bearings and holding the pivot pins of the flaps in said bearings, said locking element comprising a body and at least one connection member including a base connecting the connection member to said body of the locking element and a head wider than said base, said side pillar including, on the face thereof comprising the at least one row of bearings, at least one slot opening onto a lateral side of said side pillar having a shape complementing said at least one connection member, said at least one connection member being inserted into the at least one slot from the lateral side, the method comprising:
after the flaps have been mounted on the supporting frame, placing the at least one connection member of the locking element and the at least one slot of the supporting frame facing each other; and
translating the locking element so that the at least one connection member is inserted into the at least one slot and so that the locking element covers a row of bearings.
