Abstract: A resilient member and method of forming the same wherein the resilient member isolates the transmission of vibrations and/or sound. The resilient member (20) includes a first element (24), preferably including a contour (26), a second element (28) manufactured from a deformable material (e.g., a thermoplastic), and a resilient element (32) (e.g., rubber). The second element (28) is deformed during a molding process to conform its shape or size to the surface (25) of the first element (24). In a preferred embodiment, the second element (28) is plastically deformed to conform to a contour (26) of the first element (24) thereby forming a mechanical interlock. Rotational and translational interlocks and the method for forming same are described.
