Abstract

A protective and decorative molding for attachment to structures such as the sides of automobiles. The molding has an elongated channel-shaped plastic member, a foam which fills and extends beyond the inner channel of the plastic member, and a means for bonding the molding to an automobile body.

Claims

1. A protective and decorative molding including an elongated, channel-shaped member comprising a plastic semi-rigid elastic material and having an inwardly facing surface defining an inner space, said inwardly facing surface being an uneven and irregular surface;

a light-weight flexible, pliant foam bonded by surface attachment to said inwardly facing surface, said foam completely filling and extending beyond the inner space of said channel-shaped member, said foam presenting a generally planar surface adapted for attachment to a structural surface and said foam being compressible to substantially evenly distribute pressure against said structural surface and to provide a cushion between said channel shaped member and said structural surface; and

means for attaching said generally planar surface of said foam to said structural surface.

2. A molding as recited in claim 1 wherein said means for attaching said generally planar surface of said foam is a layer of pressure sensitive adhesive.

3. A molding as recited in claim 1 wherein said means for attaching said generally planar surface of said foam is double faced pressure sensitive tape.

4. A molding as recited in claim 1 wherein said elongated channel-shaped member is made of polyvinyl chloride and said flexible, pliant foam is made of polyurethane foam.

5. A molding as recited in claim 1 wherein said elongated, channel-shaped member has a hardness of from about 80 Shore A to about 55 Shore D.

6. A molding as recited in claim 1 having an outwardly facing surface with a decorative layer on at least a portion thereof selected from the group consisting of metal foil, metalized plastic film, and polyvinylfluoride film.

7. A molding as recited in claim 6 wherein said decorative layer of said molding has a layer of clear vinyl thereover.

8. A molding as recited in claim 6 wherein said decorative layer of said molding has a layer of ionomeric resin thereover.

9. A molding as recited in claim 6 wherein said channel-shaped member has opposite side walls, each having, in cross section, an end portion and said foam extends over at least a portion of each of said end portions and is surface bonded thereto.

10. A molding adapted to protect and decorate a supporting structural surface comprising an elongated, channel-shaped plastic member comprising a relatively incompressible elastic material and having an inwardly facing surface defining an inner space;

a relatively compressible foam filling and extending outwardly and beyond the inner space of said channel-shaped member, said foam bonded by surface attachment to the inner surface of said plastic member, said inner surface being an uneven and irregular surface; and

adhesive means for attaching said foam to said supporting structural surface.
