Abstract
Abstract A bolster wire assembly for attaching a seat cover to a resilient foam seat cushion includes a bolster wire, a stabilizing wire, and an anchor wire. The bolster wire extends continuously along the bottom wall of a slot in the foam cushion. The stabilizing wire extends in general parallel relation from the bolster wire in laterally spaced relation therefrom and is embedded within the foam cushion. The anchor wire extends in generally parallel relation from the bolster wire and is embedded within the foam cushion generally adjacent the mounting surface of the cushion which rests upon the seat frame. Connecting wires act between the stabilizing wire and the bolster wire to anchor the bolster wire against lateral movement in the seat cushion. Hog ring fasteners are receivable through the cushion slot for attaching the seat cover to the bolster wire. Additional hog ring fasteners attach the anchor wire to the seat frame. Connecting wires also act between the bolster wire and the anchor wire to anchor the bolster wire against movement relative the seat frame and thereby attach the foam cushion and seat cover to the seat frame.

Total Claims: 6
Claim 1
Independent Claim
175 words
A bolster wire assembly for embedment in a resilient foam cushion to facilitate attachment of a seat cover on a seating surface of the foam cushion and attachment of a mounting surface of the foam cushon on a seat frame, said bolster wire assembly comprising: a longitudinally extending bolster wire adapted for placement in the foam cushion generally adjacent the seating surface thereof for attachment thereto of the seat cover; stabilizing means attached to the bolster wire and adapted for embedment in the foam cushion to anchor the bolster wire against movement in the foam cushion; a longitudinally extending anchor wire adapted for placement in the foam cushion generally adjacent the mounting surface thereof and adapted for attachment to the seat frame; and means connecting the anchor wire with the bolster wire at longitudinally spaced intervals therealong so that the bolster wire is anchored to the seat frame against movement within the foam cushion by the forces imposed on the bolster wire by the seat cover during seating of an occupant upon the vehicle seat.
Claim 2
Dependent Claim
175 words
A bolster wire assembly for embedment in a resilient foam cushion to facilitate attachment of a seat cover on a seating surface of the foam cushion and attachment of a mounting surface of the foam cushon on a seat frame, said bolster wire assembly comprising: a longitudinally extending bolster wire adapted for placement in the foam cushion generally adjacent the seating surface thereof for attachment thereto of the seat cover; stabilizing means attached to the bolster wire and adapted for embedment in the foam cushion to anchor the bolster wire against movement in the foam cushion; a longitudinally extending anchor wire adapted for placement in the foam cushion generally adjacent the mounting surface thereof and adapted for attachment to the seat frame; and means connecting the anchor wire with the bolster wire at longitudinally spaced intervals therealong so that the bolster wire is anchored to the seat frame against movement within the foam cushion by the forces imposed on the bolster wire by the seat cover during seating of an occupant upon the vehicle seat.
Claim 3
Dependent Claim
186 words
A bolster wire assembly for embedment in a resilient foam cushion having a mounting surface resting upon a seat frame and an upwardly opening slot therein defined by side walls and a bottom wall to permit entry and attachment of a seat cover to the resilient foam cushion, said bolster wire assembly comprising: a bolster wire lying on the bottom wall of the slot and extending continuously therealong for attachment of the seat cover thereto; a stabilizing wire spaced laterally from the bolster wire for embedment in the foam cushion at a substantial lateral distance from the slot; an anchor wire embedded in the foam cushion adjacent the mounting surface thereof and adapted for attachment to the seat frame; and a plurality of connecting wires extending between the anchor wire, the bolster wire and the stabilizing wire at spaced longitudinal intervals therealong so that the stabilizing wire effectively anchors the bolster wire against lateral movement within the foam cushion and the anchor wire effectively mounts the bolster wire against vertical movement within the foam cushion by forces imposed upon the bolster wire by the seat cover.
Claim 4
Dependent Claim
186 words
A bolster wire assembly for embedment in a resilient foam cushion having a mounting surface resting upon a seat frame and an upwardly opening slot therein defined by side walls and a bottom wall to permit entry and attachment of a seat cover to the resilient foam cushion, said bolster wire assembly comprising: a bolster wire lying on the bottom wall of the slot and extending continuously therealong for attachment of the seat cover thereto; a stabilizing wire spaced laterally from the bolster wire for embedment in the foam cushion at a substantial lateral distance from the slot; an anchor wire embedded in the foam cushion adjacent the mounting surface thereof and adapted for attachment to the seat frame; and a plurality of connecting wires extending between the anchor wire, the bolster wire and the stabilizing wire at spaced longitudinal intervals therealong so that the stabilizing wire effectively anchors the bolster wire against lateral movement within the foam cushion and the anchor wire effectively mounts the bolster wire against vertical movement within the foam cushion by forces imposed upon the bolster wire by the seat cover.
Claim 5
Dependent Claim
171 words
A vehicle seat comprising: a seat cover; a seat frame; a resilient foam cushion having a seating surface with an upwardly opening slot therein defined by side walls and a bottom wall and a mounting surface; a bolster wire extending continuously along the bottom wall of the slot generally intermediate the side walls thereof; a stabilizing wire extending in generally parallel relation from the bolster wire in laterally spaced relation therefrom and embedded within the foam cushion; an anchor wire extending in generally parallel relation from the bolster wire and embedded within the foam cushion generally adjacent the mounting surface thereof; connecting wires acting respectively between the stabilizing wire and the bolster wire and between the bolster wire and the anchor wire; fastener means receivable through the slot for attaching the seat cover to the bolster wire at any selected point along the continuous length thereof; and fastener means attaching the anchor wire to the seat frame at any selected point therealong to attach the foam cushion to the seat frame.
Claim 6
