Abstract

A filter trap for a motor vehicle thermal device is made of polymer material and includes two longitudinal edges extending along a length thereof connected by two lateral edges extending along a width thereof. The trap includes a first assembly tab extending along the length thereof and fixed to one of the lateral edges. The trap also includes a snap coupling to block the trap. The snap-coupling is fixed to one of the longitudinal edges and is located in the vicinity of another of the lateral edges. The trap also includes a second assembly tab extending perpendicular to the first assembly tab. The second assembly tab is fixed to another of the longitudinal edges and is located in a vicinity of another of the lateral edges. The trap has sufficient flexibility along the length thereof to permit twisting of the trap about a longitudinal torsion axis of the trap.

First claim

1 - 9 . (canceled)

10 . A filter trap for a motor vehicle thermal device, said trap made of polymer material being of planar elongated shape, having a length and having two longitudinal edges extending along the length thereof connected by two lateral edges extending along a width thereof, said trap comprising:
a first assembly tab extending in an extension of the trap along the length thereof, said first assembly tab being fixed to a first of the two lateral edges; a snap-coupling configured to block said trap in a direction perpendicular to the plane of the trap, said snap-coupling being fixed to a first of the two longitudinal edges and being located in a vicinity of a second of the two lateral edges, which does not bear the first assembly tab; a second assembly tab extending in the extension of the trap in a direction perpendicular to the first assembly tab, said second assembly tab being fixed to a second of the two longitudinal edges, which does not comprise the snap-coupling means, and said second assembly tab being located in a vicinity of the second of the two lateral edges, which does not bear the first assembly tab, wherein said trap is configured to have a sufficient flexibility along the length thereof to permit twisting of said trap about a longitudinal torsion axis of the trap.

11 . The trap as claimed in claim 10 , wherein the trap is configured to permit an angle of torsion of 15° to 50° between the two lateral edges of the trap.

12 . The trap as claimed in claim 11 , wherein the angle of torsion is 20° to 45°.

13 . The trap as claimed in claim 10 , wherein the snap-coupling and the second assembly tab are arranged symmetrically relative to the longitudinal torsion axis of the trap.

14 . The trap as claimed in claim 10 . wherein the snap-coupling and the second assembly tab are remote from the adjacent lateral edge by a distance which is less than or equal to L/3, L being the length of the trap.

15 . The trap as claimed in claim 10 , wherein the snap-coupling and the second assembly tab are remote from the adjacent lateral edge by a distance which is less than or equal to L/4, L being the length of the trap.

16 . The trap as claimed in claim 10 . wherein the snap-coupling and the second assembly tab are remote from the adjacent lateral edge by a distance which is less than or equal to L/6, L being the length of the trap.

17 . The trap as claimed in claim 10 , wherein the first and second assembly tabs have a thickness which is less than a thickness of said trap.

18 . The trap as claimed in claim 17 , wherein the thickness of the first and second assembly tabs is equal to a maximum of 90% of the thickness of said trap.

19 . The trap as claimed in claim 17 , wherein the thickness of the first and second assembly tabs is equal to a maximum of 70% of the thickness of said trap.

20 . The trap as claimed in claim 10 , wherein the first and second assembly tabs have a face extending in an extension of a face of the trap.

21 . A motor vehicle thermal device, comprising:
a casing perforated by an opening for access to a filter, said casing being provided with a filter trap as claimed in claim 10 , said filter trap being shaped so as to seal said opening, wherein said thermal device further comprises, on a periphery of said opening:
means for engagement which is shaped so as to cooperate with the snap-coupling means of the trap to block the trap in a direction perpendicular to the plane thereof, and
a first retaining tab and a second retaining tab, each retaining tab defining with the casing a space having a shape which is complementary to one of the assembly tabs of the trap, the first and second retaining tabs being positioned such that the first and second assembly tabs are respectively inserted between said retaining tabs and the casing when said trap seals the opening.

22 . The thermal device as claimed in claim 21 , wherein a maximum height of one of the retaining tabs that is perpendicular to a surface of the casing is less than or equal to twice a thickness of the trap.

23 . (brew): A motor vehicle, comprising:
a thermal device as claimed in claim 21 .
