Abstract
A constant section gasket based on elastomer, plastic, or like material, the gasket comprising a constant section element that is extruded or molded in at least one material selected from elastomers, plastics, thermoplastic elastomers, and the like materials. The gasket also includes a sole-piece for fixing on a support(s), in particular a metal part of car bodywork, with the sole-piece being fixed thereto by means of an induction heating machine.
Claims7
A two-part constant section gasket assembly for an automobile comprising:
- an elastic member having a constant section, made from at least one material selected from the group consisting of elastomers, plastics, and thermoplastic elastomers,
- a sole-piece formed by a beam having at least an outside portion and a fixing member with at least an engaging portion for fixing said gasket on a metal part of a car,
- said outside portion of said sole-piece and said elastic member having complementary shapes through which there are securely assembled together as a unitary one-piece assembly consisting of said elastic member and said sole-piece;
- said fixing member being spaced from said elastic member and at least said fixing member being formed from a material selected from the group consisting of plastics and thermoplastics adapted to be fixed firmly on said support by the application of induction heating, and
- both said elastic member and said sole-piece being made from separate prior manufacturing steps selected from the group consisting of extrusion and molding.
