Abstract
This invention provides a system and method for attaching a trim cover to a flexible/resilient substrate, typically constructed from foam, which includes a plurality of clips that each has a base molded into the substrate. The bases each include a central “key-hole” slot that receives a corresponding key formed on a stem at a bottom of a clip projection. The clip projection defines a cavity for receiving a trim cover bead through a gap formed between a pair of legs that extend from the bottom. The stem has a length that is approximately the thickness of the slot. By passing the key through the slot and rotating the key to a locked position, the clip projection may be removably mounted to the substrate for repair or replacement as needed. The base may be constructed from a material that adheres effectively to the substrate, while the clip projection may be constructed from a material that exhibits high elasticity and wear-resistance. A cradle that includes a pair of upright posts that each confront a leg may be provided to progressively support the legs so as to prevent single point stresses from forming in the legs.
