Abstract
Abstract The supporting members of a vehicle seat includes a molded plastic seat bottom support member and a molded plastic seat back support member. Cushion members for mounting on the support members 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 resilient retainer wire extends around the opening and is attached to the edges of the seat cover by J-shaped plastic hook strips so that the resilience of the foam bun exerts tension of the retainer wire. The retainer wire has a plurality of abutment structures integral therewith and adapted for mating engagement with corresponding abutments provided on the seat support members when the cushion member is forcibly stressed to flex the retainer wire. Termination of the stressing effort applied to the cushion member allows the resilience of the retainer wire and the tension applied to the seat cover by the compressed cushion bun to maintain the engagement of the retainer wire abutments with the abutments of the support member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
261 words
A vehicle seat comprising: a support member having a generally planar support wall; a seat cushion for mounting on the support member in engagement with the support wall of the support member, said seat cushion having a cushion bun of resilient foam for comfortably seating an occupant on the support member and a seat cover enveloping the cushion bun, the seat cover having an edge portion and an opening adjacent the edge portion through which the cushion bun may be inserted by compressing the cushion bun and then allowing expansion of the cushion bun to fill the seat cover; a resilient retainer wire extending around the opening and being attached along the edge portion of the seat cover so that the resilience of the foam bun urges the seat cover outwardly in the direction enlarging the opening and exerting tension on the retainer wire; a plurality of abutment means on the support member and a plurality of cooperable abutment means formed integrally in the retainer wire, the respective abutment means being matingly engageable upon flexure of the retainer wire in the direction which decreases the size of the opening of the seat cover and opposes the tensioning effort exerted on the border wire by the resilience of the cushion bun acting on the seat cover whereby the resilience of the cushion bun cooperates with the resilience of the retainer wire to maintain the integrally formed abutment means on the retainer wire in engagement with the mating abutment means on the support member to attach the seat cushion on the support member.
Claim 2
Dependent Claim

A vehicle seat comprising: a support member having a generally planar support wall; a seat cushion for mounting on the support member in engagement with the support wall of the support member, said seat cushion having a cushion bun of resilient foam for comfortably seating an occupant on the support member and a seat cover enveloping the cushion bun, the seat cover having an edge portion and an opening adjacent the edge portion through which the cushion bun may be inserted by compressing the cushion bun and then allowing expansion of the cushion bun to fill the seat cover; a resilient retainer wire extending around the opening and being attached along the edge portion of the seat cover so that the resilience of the foam bun urges the seat cover outwardly in the direction enlarging the opening and exerting tension on the retainer wire; a plurality of abutment means on the support member and a plurality of cooperable abutment means formed integrally in the retainer wire, the respective abutment means being matingly engageable upon flexure of the retainer wire in the direction which decreases the size of the opening of the seat cover and opposes the tensioning effort exerted on the border wire by the resilience of the cushion bun acting on the seat cover whereby the resilience of the cushion bun cooperates with the resilience of the retainer wire to maintain the integrally formed abutment means on the retainer wire in engagement with the mating abutment means on the support member to attach the seat cushion on the support member.
Claim 3
Dependent Claim
199 words
A vehicle seat comprising: a support member having a generally planar support wall; a cushion bun of resilient foam for mounting on the support wall of the support member to comfortably seat an occupant on the support member; a seat cover for enveloping the cushion bun and having an edge portion and an opening defined by the edge portions of the seat cover; a J-shaped extruded plastic strip having a shank portion and a hook portion, the shank portion being attached along the edge portion of the seat cover; a flexible retainer wire extending along at least a portion of the edge portion of the seat cover around the opening and being inserted in the J-shaped hook strip, the resilience of the foam bun urging the seat cover outwardly in the direction enlarging the opening so that the retainer wire is captured in the hook portion of the J-shaped strip; and attaching means acting between the support member and the retainer wire at spaced intervals along the retainer wire, the resilience of the cushion bun cooperating with the resilience of the retainer wire to maintain tension on the attaching means acting between the support member and the retainer wire.

Claim 5
Dependent Claim
193 words
A vehicle seat comprising: a seat support member having a generally planar support wall; a cushion bun of resilient foam for mounting on the support wall; a seat cover enveloping the cushion bun and having an edge portion defining an opening therein through which the cushion bun is inserted by compressing the cushion bun and then allowing expansion of the cushion bun to fill the seat cover; J-shaped hook means having a shank portion attached along the edge portion of the seat cover and a hook portion extending into the opening; a flexible retainer wire extending around the edge portion of the seat cover and being engaged by the hook of the J-shaped hook means, the resilience of the foam bun urging the seat cover outwardly in the direction enlarging the opening so that the retainer wire is maintained in captured engagement of the hook portion of the hook means; a plurality of abutment means formed integrally with the retainer wire; and a pluraity of abutment means carried by the support member and being matingly engageable by the abutment means of the retainer wire to attach the seat cushion on the support member.
