Abstract

The invention concerns a device (1) for protecting a breather membrane (2) enabling the ventilation of a member, notably a gear motor of a wiper system, said device including a support (3) intended to accommodate said membrane (2) on the surface of said member and a cover (4) for protecting said membrane (2), said device (1) being configured to allow circulation of air between the interior and the exterior of the member via said membrane (2).

According to the invention, said cover (4), moulded in one piece with said support (3), is articulated relative to said support (3) so as to enable fixing of said membrane (2) onto said support (3) in an open position of said cover (4) and to cover said membrane (2) in a closed position of said cover (4).

Claims

1. A device for protecting a breather membrane enabling the ventilation of a gear motor of a wiper system, said device comprising:

a support intended to accommodate said membrane on a surface of said member and a cover for protecting said membrane, said device being configured to allow circulation of air between an interior and an exterior of the member via said membrane, wherein said cover, moulded in one piece with said support, is articulated relative to said support so as to enable fixing of said membrane onto said support in an open position of said cover and to cover said membrane in a closed position of said cover.

2. The device according to claim 1, further comprising an articulation hinge between said support and said cover.

3. The device according to claim 2, wherein said hinge is adapted to separate easily.

4. The device according to claim 2, wherein said support includes a surface for fixing said membrane, and wherein said hinge is situated in a plane different from that of said surface for fixing the membrane.

5. The device according to claim 1, wherein said cover is adapted to be clipped to said member.

6. The device according to claim 1, wherein said cover is fixed to said support.

8. A gear motor provided with a breather membrane and a device according to claim 1 for protecting said membrane.

9. The gear motor according to claim 8, comprising a housing accommodating a gear mechanism, said protection device being made in one piece with said housing.

10. A wiper system provided with a gear motor according to claim 8.

7. The device according to claim 7, wherein said cover is clipped onto said support.
