Abstract
Abstract The present invention is directed to a chair construction and a method for fabricating such a chair. At least a portion of the chair frame is adapted to be upholstered with a removable decorative cover, and that portion - or a component thereof may, comprise a shell having a mounting flange and a groove extending around the perimeter of the shell in substantially parallel relation with respect to the mounting flange. A bumper embraces the mounting flange and presents an anchor rib that is received within the groove. The configuration of the exterior of the bumper as well as the anchor rib cooperates with the shell to prevent inadvertent removal. A cover overlies the shell and is secured to the bumper by hidden stitching. The cover may be infolded within the resilient cushion material interposed between the cover and the shell to present one or more decorative grooves and to preclude stressing the stitching by which the cover is secured to the bumper.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
108 words
A chair having a frame, at least one portion adapted for removably receiving a cover, said assembly comprising; a mounting flange defining the perimeter of that portion of the seat frame adapted to receive the cover, a groove located adjacent said mounting flange and extending in substantially parallel relationship to said mounting flange, a bumper, said bumper having first and second opposed jaws conjoined to embrace said mounting flange, an anchor rib presented from one of said jaws and oriented to extend toward said second jaw, said anchor rib being releasably received within said groove, a cover, and means to secure said cover to one of said jaws.
Claim 2
Dependent Claim
108 words
A chair having a frame, at least one portion adapted for removably receiving a cover, said assembly comprising; a mounting flange defining the perimeter of that portion of the seat frame adapted to receive the cover, a groove located adjacent said mounting flange and extending in substantially parallel relationship to said mounting flange, a bumper, said bumper having first and second opposed jaws conjoined to embrace said mounting flange, an anchor rib presented from one of said jaws and oriented to extend toward said second jaw, said anchor rib being releasably received within said groove, a cover, and means to secure said cover to one of said jaws.
Claim 3
Dependent Claim

A chair, as set forth in claim 1, in which the cover is secured to said second jaw.
Claim 4
Dependent Claim
26 words
A chair, as set forth in claim 2, in which the means to secure the cover to the second jaw of said bumper comprises hidden stitching.
Claim 5
Dependent Claim
38 words
A chair, as set forth in claim 1, in which the cover has an edge that overlies the second jaw of said bumper, an inseam flap underlies said cover, said inseam flap being stitched to said second jaw.
Claim 6
Dependent Claim
38 words
A chair, as set forth in claim 1, in which said first and second jaws are conjoined along a juncture, said anchor rib being presented from the edge of said first jaw distal with respect to said juncture.
Claim 7
Dependent Claim
52 words
A chair, as set forth in claim 5, in which the mounting flange has a generally planar terminal surface and a generally planar surface is presented from said first jaw medially of said juncture and said anchor rib, said planar surface on said first jaw being adapted to engage said terminal surface.
Claim 8
Dependent Claim
60 words
A chair, as set forth in claim 1, in which the portion of the chair adapted to receive the cover comprises a load bearing structural shell with first and second oppositely directed face walls, said mounting flange defining the perimeter of said shell and said groove extending inwardly of said first face wall, said cover overlying said second face wall.
Claim 9
Dependent Claim
33 words
A chair, as set forth in cLaim 7, in which said first jaw presents an outwardly directed surface, said outwardly directed surface terminating in juxtaposition to the first face wall of said shell.
