Abstract

The present invention is directed to a molded foamed automobile cushion having a deep groove and an upholstery cover secured thereto by a touch fastener having cooperating hook and loop elements carried by the cushion and cover. One element of the touch fastener is molded into a deep groove in the cushion and the other element is secured to the upholstery. The hook elements on both sides of the groove are unidirectional, when assembled, and have their concave surfaces facing in the same direction to permit easy entry of the upholstery into the groove and providing maximum resistance to removal of the upholstery from the groove.

Claims

1. An article of manufacture for use in forming a foamed seat cushion with a foamed-in loop fastener tape, said article comprising an elongated tape having a fastener surface containing either hook or loop fastening elements on one surface and a flexible plastic V-shaped support for said tape, said support having a pointed ridge over which the center portion of said tape is placed with the fastening surface facing said support, said support also having sealing means for holding the lateral edges of the tape and means for securing said support to the surface of a mold.

2. The article of claim 1 wherein the sealing means comprises upwardly extending clamp means for releasably holding said tape along its edges to prevent foam constituents from travelling to the fastening surface of the tape.

3. The article of claim 2 wherein the clamp means includes longitudinal grooves, the grooves being formed by upstanding legs whose lower extremities form foam-tight seals with the mold surface and detent means partially closing said grooves.

4. The article of claim 1 wherein the support member has means for engaging a holding device mounted on the mold surface and holding said support in foam-tight engagement with the mold surface.

5. An article of manufacture for use in forming a foamed seat cushion with a foamed-in loop fastener tape, said article comprising an elongated tape containing loops on one surface and a flexible plastic V-shaped support for said tape, said support having a pointed ridge over which the center portion of said tape is placed with the loop surface facing said support, said support also having sealing means for holding the lateral edges of the tape and means for securing said support to the surface of a mold.

6. A foamed cushion incorporating the article of claim 5 wherein the means for securing the support to the surface of the mold has a weaker bond to the mold than that between the foamed cushion and the fastener tape.

7. The foamed cushion of claim 6 wherein the bond between the sealing means and the support is weaker than the bond between the tape and the foam.

8. An article of manufacture for use in forming a foamed seat cushion with a foamed-in loop fastener tape, said article comprising an elongated tape containing hooks on one surface and a flexible plastic V-shaped support for said tape, said support having a pointed ridge over which the center portion of said tape is placed with the hook surface facing said support, said support also having sealing means for holding the lateral edges of the tape and means for securing said support to the surface of a mold.
