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

1. A method for fabricating a chair comprising the steps of;

providing a chair having a frame which presents a mounting flange around the periphery thereof, forming a continuous bumper the cross section of which is adapted to embrace the peripheral flange of the chair frame, disposing said bumper in introverted position on the finished surface of the material from which a cover is to be formed, securing said bumper to the cover material, retrorotating the bumper with the cover material secured thereto, and mounting said bumper on said chair frame by positioning said bumper embracingly to engage the mounting flange along the periphery of the chair frame.

2. A method for fabricating a chair, as set forth in claim 1, comprising the additional steps of;

providing a template, and releasably securing the continuous bumper to the template so that the bumper will be oriented according to a predetermined pattern before it is secured to the cover material.

3. A method for fabricating a chair, as set forth in claim 2, in which the bumper is secured to the cover material by stitching.

4. A method for fabricating a chair, as set forth in claim 3, in which the bumper is formed by the additional steps of;

extruding a continuous ribbon, cutting a strip of predetermined length from said ribbon, hooping said strip to abut the opposed ends of the strip, and joining the abutting ends of said strip to form a bumper.

5. A method for fabricating a chair, as set forth in claim 4, comprising the additional steps of;

selecting the predetermined length of the strip to be less than the lineal dimension required for a bumper to be mounted on the frame, and stretching the hooped bumper to its mounted dimension when releasably securing the bumper to the template.

6. A method for fabricating a chair, as set forth in claim 3, comprising the additional step of;

interposing a resilient cushion material between the shell and the cover.

7. A method for fabricating a chair, as set forth in claim 6, comprising the additional steps of;

providing an interface in the resilient cushion material, securing a pad to the cover, and buttonholing the tab through the interface to infold a portion of the cover.

8. A method for fabricating a chair, as set forth in claim 2, comprising the additional steps of;

providing a slot in the template, placing a mark on the cover material along the slot in said template, securing a tab to the cover material along the mark, and buttonholing the tab through the interface to infold a portion of the cover.
