Abstract

A sealing gasket comprising at least one zone for putting into contact via a sealing barrier with a gasket-receiver support such as a rabbet on a frame surrounding a recess for a moving panel in the automobile industry or a contact zone between two stationary panels in the construction industry, wherein said sealing barrier comprises a rubber composition based on at least one thermoplastic elastomer of compact type presenting hardness on the Shore A scale, measured using the ASTM D 2240 standard, that is less than or equal to 40.

Claims

1. An assembly comprising:

a gasket-receiver support having a rabbet on a frame surrounding a recess for a moving panel in the automobile industry, and

a sealing gasket comprising at least one zone which is mounted on said support and which comprises a sealing barrier in contact with said support, said sealing barrier comprising a rubber composition based on at least one thermoplastic elastomer, said thermoplastic elastomer is of non-expanded compact type and presents a hardness on the Shore A scale, measured using the ASTM D 2240 standard, that is less than or equal to 40, and

wherein the gasket presents a fastener clamp forming the zone of the gasket that is to be put into contact with the gasket-receiver support such as a rabbet, said clamp being substantially of channel-section presenting a web and two lateral flanges, and in which said sealing barrier is mounted against the web of the clamp for providing sealing relative to said support.

2. The assembly according to claim 1, in which said thermoplastic elastomer presents hardness on the Shore A scale less than or equal to 20.

3. The assembly according to claim 2, in which said thermoplastic elastomer presents hardness on the Shore A scale that is substantially equal to 0.

4. The assembly according to claim 1, in which said thermoplastic elastomer is a styrene thermoplastic elastomer.

5. The assembly according to claim 4, in which said styrene thermoplastic elastomer is a styrene/ethylene/butylene/styrene (SEBS) block copolymer.

6. The assembly according to claim 4, in which said styrene thermoplastic elastomer is a styrene/ethylene/propylene/styrene (SEPS) block copolymer.

7. The assembly according to claim 1, in which the sealing barrier is co-extruded on the zone of the gasket that is to come into contact with the gasket-receiver support.

8. The assembly according to claim 1, in which the zone of the gasket that is to come into contact with the gasket-receiver support is based on a terpolymer of ethylene/propylene/diene monomer (EPDM), or of a thermoplastic elastomer (TPE, TPO, or TPV) of the type comprising a mixture of a polyolefin and a rubber such as an EPDM.

9. The assembly according to claim 7, in which the sealing barrier is of arched shape.

10. The assembly according to claim 1, wherein a reinforcement is embedded in the fastener clamp.
