Abstract
Abstract The support members for a vehicle seat include a molded plastic seat bottom support and a molded plastic seat back support. Cushion members for mounting on the supports include a cushion bun of resilient foam and a seat cover for enveloping the cushion bun. The seat cover has an opening in the underside thereof which permits insertion of the cushion bun when the cushion bun is compressed. A fastening device for mounting the cushion member includes a projecting element, preferably a headed stud, provided on the cushion member. A mating receptacle element, preferably a slot or key hole slot, is provided on the support. The projecting element and the receptacle element are positioned for mating engagement when the cushion bun is forcibly stressed to vary the spaced relation between the fastening devices provided at the respective ends of the cushion member. Termination of the stressing effort applied to the cushion allows the resilience of the cushion bun and the tension exerted thereon by the seat cover to return the ends of the cushion member toward their normal spaced relation so that the projecting elements are captured in their mating receptacle elements to mount the cushion member on the support member. A rigid panel of cardboard or the like is molded in situ on the underface of the cushion bun and has an edge coextensive with the edge of the cushion bun to resist the tension on the seat cover from compressing the corners of the cushion bun. A pair of these rigid panels may be employed which are spaced from one another so as to permit the compression of the cushion member and insertion of the cushion bun into the opening of the seat cover as well as deformation of the cushion bun sufficiently to align the projecting elements and mating receptacle elements of the fastening devices which are mounted on the rigid panels.
