Abstract

A composite cushion assembly, useful as a padded structure in an automotive vehicle compartment, is disclosed along with the method for making same. The composite assembly has an outer skin formed of flexible-resilient polyvinyl chloride material, the skin forming a cavity into which a foaming composition is injected, the foam upon rigidifying being self-bonded to the skin and providing a material having a resiliency considerably greater than the resiliency of the outer skin. The outer skin is nonstressed during the molding operation with reliance being placed upon an adhering agent to insure a sound bond between the composite materials. The outer skin and foam are defined with openings to receive a supporting structure when the former is mounted thereon; the skin has an integral resilient annular member for installation on the supporting structure by snapaction, the annular member insuring a taunt installed condition for the composite cushion.

Claims

1. A padded vehicle seating structure, comprising:

a. a rigid subframe having a substantially annular member at least at one side thereof, and having a flange continuously adjacent said annular member, b. a preformed continuous composite cushion effective to be supported by said subframe and effective to surround substantially all sides of said subframe except for the space defined within said annular member, said composite cushion being comprised of a flexible abrasion resistant skin and a solid flexible foam substrate, each being bonded to the other, said skin having a continuous annular terminating portion adjacent one side of said annular member and having a continuous depending wall extending beyond said substrate for carrying said terminating portion, said solid foam substrate being defined with a continuous groove adjacent at least three sides of said substrate and said groove opening to said one side, said subframe having portions thereof adapted to extend into and be received by said cushion groove for stabilizing same when mounted thereon, and c. means defining a resilient ring integral with said terminating portion of sAid skin and effective to grip a continuous side of said annular member opposite from said member one side, said ring means being effective to permit snap-tight mounting of said composite cushions on said subframe and having said skin arranged to permit transmission of tension forces throughout as received from said ring, said continuous depending wall being in engagement with said subframe flange adjacent said annular member.

2. The structure as in claim 1, in which the cushion has a central portion generally uniform in thickness taken in one lateral direction and partially parabolic in variation in thickness taken in a longitudinal direction.
