Claim Text:
1. A method for forming a strap having first and second regions continuously joined to each other without interruption, comprising the steps of: forming the first region by injecting a first polymeric material into a first mold, the first region defining a longitudinal core of the strap; forming the second region by injecting a second polymeric material in a second mold about peripheral edge portion to the first region; wherein the first polymeric material is a first thermoplastic elastomer, and the second polymeric material is a second thermoplastic elastomer; wherein the first and second polymeric materials are integrally molded together and chemically bonded at least at an interface between the first and second regions due to a similarity in composition of the first and second polymeric materials, the first thermoplastic elastomer having greater rigidity than the second thermoplastic elastomer.
