Abstract

In a vehicle seat, the improvement comprising a seat cover positioned on a contoured foam cushion, both being held together by means of upper and lower parallel wires fastened together along their lengths. The lower wire is embedded in the foam cushion parallel to and below the demarcation between the seating portion and bolster portions of the upper surface of the cushion. The upper wire is entrapped within a sleeve fastened to the underside of the seat cover and is generally parallel to the lower wire. The upper and lower wires are fastened together by fastening means which pierce the sleeve.

Claims

1. In a vehicle seat, the improvement comprising:

a. a resilient foam seat cushion having a lower and upper surface, said upper surface being contoured generally into a seating portion and bolster portions along the boundary of said seating portion, b. a lower wire foamed into said seat cushion and running below said upper surface and above said lower surface and disposed parallel to the boundary of said seating portion, c. a seat cover having an exposed surface and having an underside in contact with said upper cushion surface, d. a sleeve fastened to the underside of said seat cover to follow the boundary of said seating portion, e. an upper wire entrapped by said sleeve positioned in substantially vertical and parallel alignment with respect to said lower wire, f. spaced fastening means positioned under said upper surface and above said lower surface, said fastening means binding said lower and upper wires together along the lengths of said wires, whereby said sleeve and said upper and lower wires are secured in substantially vertical juxtaposed position and g. a groove in the upper surface of said cushion at the boundary of said seating portion delineating said upper surface into said seating portion and said bolster portions and accommodating said sleeve, thereby preventing the occurrence of a ridge in said exposed surface of said seat cover due to said sleeve and said upper wire.

2. The improved vehicle seat of claim 1 further characterized in that said seat cushion is constructed of flexible polyurethane foam.

3. The improved vehicle seat of claim 1 further characterized in that a strip of flexible material is positioned near the underside of said seat cover to follow the boundary of said seating portion of said upper cushion surface, and the edges of said strip are folded together to form a sleeve and are fastened to the underside of said seat cover.

4. The improved vehicle seat of claim 1 further characterized in that said seat cover is comprised of a single expanse of covering material.

5. The improved vehicle seat of claim 1 further characterized in that said seat cover is comprised of a plurality of separate sections of joined covering material.
