发明名称 Apparatus and method for upholstering a rigid chair shell
摘要 An apparatus and method for upholstering a rigid chair shell is disclosed. A continuous, generally C-shaped track is utilized about the peripheral edge of the shell, opening rearwardly thereof to receive a retaining element attached about the peripheral edge of the covering material. The retaining element is constructed from a strip of tubular flexible material with an integral flap member circumferentially overlying at least part of the tubular strip and accepting the track edge therebetween. The inside surface of the outer end of the flap member is attached to the inside surface of the edge of the cover or fabric and, after suitable cushioning is attached to the front surface of the shell, the covering is placed over the cushioning and rolled about the retaining element which is snapped into the C-shaped track around the periphery of the shell to hold the covering thereon. Upon rolling into the track the tubular body is seated in the track cavity, and the free edge of the track extends into the space between the tubular body and the flap member with the fabric end disposed therebetween, thus locking the element against the track edge preventing roll-out and distributing the stress on the fabric while blending the region between the cushion and shell edges and obscuring the retaining element from view. The composite cover, cushion, and shell is then placed face up in an upholstery mold and heat and pressure applied from above to conform and attach the cover to the cushion by activating a non-tacky cover-cushion adhesive on the surface of the cushion, and a finished composite chair results upon removal from the mold. For reupholstery purposes, a replacement fabric, cushion and retaining element may be preformed and locked onto a shell by rolling the retaining element into the track, after the original covering, retaining element, and cushioning have been cut and removed.
