Automotive bolster with soft feel and method of making the same
First Claim
1. An automotive bolster with soft feel, comprising:
- a substrate made from a first and second material, the second material being different than the first material and defining an outer skin layer which completely surrounds the first material, the substrate further including at least one heat stake member adapted to secure the bolster to a trim panel, the at least one heat stake member being formed from at least one of the first and second materials; and
a cover made from a third and fourth material, the fourth material being different than the third material and defining an outer skin layer which surrounds the third material, the cover being integrally molded to at least a portion of the substrate, wherein at least one of the materials provides the bolster with a soft feel.

Abstract
The present invention provides for an improved bolster with a soft feel for use in a trim assembly, and to a continuous two-shot molding operation that may be continuously performed utilizing a single mold assembly. In an exemplary embodiment, the bolster includes a substrate formed by co-injecting a first and second material into a first shot mold cavity in a first shot of a molding operation. In a second shot mold cavity, a cover is formed on at least a portion of the substrate by co-injecting into a mold chamber a third and fourth material in a second shot of the molding operation. The fourth material defines an outer skin surrounding the third material which may include a foamed material to provide a soft, light cellular inner core such that when a force is applied to the cover, the outer skin will deform and compress the inner core, providing a soft feel to the bolster.
