Abstract

A bolster wire assembly is embedded in the resilient foam cushion of a vehicle seat to permit attachment of a seat cover to the foam cushion. The bolster wire assembly includes a wire having a strip of molded plastic mesh attached to and extending continuously therealong. The strip of plastic mesh has a plurality of interstices therein permitting the foam to flow through the plastic mesh during the foaming of the resilient foam cushion so that the strip of plastic mesh is embedded in the foam cushion to thereby anchor the bolster wire in the foam cushion. Conventional fasteners such as hog rings may then be employed to attach a list on the seat cover to the bolster wire.

Claims

1. A vehicle seat comprising:

a resilient foam cushion having an upwardly opening slot therein defined by side walls and a bottom wall, a plastic mesh strip having interstices therein, the plastic mesh strip traversing the slot across the bottom wall thereof and being visible at the bottom of the slot, the plastic mesh strip having portions thereof extending beyond the side walls of the slot with a plurality of the interstices having foam therein to embed the mesh strip in the foam cushion, a wire underlying the mesh strip and extending continuously along the bottom wall of the slot generally intermediate the side walls thereof, a strip of fabric of a width greater than the diameter of the wire and underlying the wire, the strip of fabric being sewn to the strip of plastic mesh with the wire captured therebetween to attach the wire to the mesh strip so that the wire is visible at the bottom of the slot through the interstices in the plastic mesh strip, a seat cover having a portion thereof received into the slot and positioned adjacent the mesh strip, and fastener means receivable through the slot for attaching the seat cover to the wire at any selected point along the continuously visible length of the wire at the bottom of the slot.

2. A bolster wire assembly for embedment in the resilient foam cushion having an upwardly opening slot therein defined by side walls and a bottom wall to permit entry and attachments of a seat cover to the resilient foam cushion, said bolster wire comprising:

a wire lying on the bottom wall of the slot and extending continuously therealong, a plastic mesh strip overlying the wire and having interstices therein, the plastic mesh strip having portions thereof extending beyond the side walls with foam received in the interstices to embed the mesh strip in the resilient foam cushion, a strip of fabric sewn to the strip of plastic mesh with the wire captured therebetween to attach the wire to the mesh strip, the interstices in the plastic mesh strip rendering the wire visible along the bottom wall of the slot to facilitate application of fastener means acting between a seat cover and the wire at any selected point along the continuously visible length of the wire at the bottom of the slot.

3. A bolster wire assembly for embedment in a resilient foam cushion having an upwardly opening slot therein defined by side walls and a bottom wall to permit entry and attachments of a seat cover to the resilient foam cushion, said bolster wire comprising:

an extruded plastic member including a longitudinally extending central backbone having a wire therein and lying on the bottom wall of the slot and extending continuously therealong, longitudinally extending outboard members spaced laterally each side of the backbone and being embedded in the foam beyond the side walls, longitudinally extending integrally extruded ribs connecting the central backbone with the outboard members, the ribs having interstices cut therein along the length thereof to permit flow of foam through the extruded plastic member during foaming of the resilient cushion to permit embedment of the bolster wire assembly in the resilient foam cushion to anchor the central backbone in a visible position along the bottom wall of the slot and thereby facilitate application of fastener means acting between the seat cover and the central backbone at any selected point along the continuously visible length of the central backbone.
