DETAILED DESCRIPTION
A chair construction of the present invention is generally indicated at 10 in Figure 1. Like reference characters will be used to indicate like elements in the drawings. Although a chair construction is specifically illustrated, it is understood that the present invention is applicable to other furniture constructions. The present invention also includes a method of placing a section of fabric 12 in tension between two rigid seat members 14 and 16. As specif tally illustrated, the section of fabric 12 and the rigid seat members and 16 form a seat portion 18 of the chair construction 10. The method of the present invention is also used to form a back portion 34 of the chair construction. Although a single seat chair . is illustrated, the method of the present invention may be used for chairs providing for more than single occupancy or which have more than one seat and back portion.
The chair construction 10 includes a framework 20 that can be made of plastic, aluminum or steel. The framework includes legs 22, 24, 26 and 28. A front crossbrace 25 and a rear crossbrace 27 extend between and connect the legs 26 and 28 and the legs 22 and 24, respectively. In the embodiment illustrated, the legs 26 and 28 have upper portions 30 and 32 which ~ serve as arms and which are integrally conjoined behind the back portion 34. The particular construction of the framework 20 is not especially important to the present invention, and is described herein as one-exemplary type of framework for which the present invention is suitable.
To form the seat portion 18, the rigid seat members 14 and 16 are provided with a downwardly facing slot 36 as best illustrated in Figures 2 and 3.
The slot 36 runs the length of the rigid members. The section of fabric 12 includes a semi-rigid or rigid edge portion 38 that extends along the length of opposing edge portions. The fabric section 12 overlies the seat member 16 along an outwardly facing side 31 adjacent to the slot 36 and extends over an upwardly facing side 41, as illustrated in Figure 3. Although only the seat member 16 is specifically illustrated in Figure 3, the seat member 14 is similar as a mirror image in both construction and how the fabric section 12 overlies the seat member 14.
-The semi-rigid or rigid edge portion 3$ is sufficiently rigid to secure the section of fabric 12 xo the seat member 16 by engagement with the slot 36. Preferably, the edge portion 38 is made of a section of plastic 40 that is attached to an edge portion 42 of the section of fabric 12 by a method that is well known. For example, such rigid edge portions are provided to canvas tops for Jeep Wrangler vehicles made by Chrysler-Daimler to secure the canvas in . certain places along the vehicle by engaging , selectively positioned slots.
It should be understood that other constructions and methods are included within the present invention to make the edge portion 38 sufficiently rigid to secure the fabric to either seat member 14 or 16. By sufficiently rigid is meant that once the edge portion is positioned within the slot and the fabric is placed along the adjacent side 31, the edge portion is retained within the slot since the edge portion cannot slide out due to its rigidity.
The section of fabric 12 is made of a stretch fabric woven from an all-weather, vinyl-coated, flexible and elastic polyester yarn, such as PHIFERTEX~ fabric made by Phifer Wire Products; Inc, of Tuscaloosa, Alabama. An example of a stretchable fabric useful in this invention is described in U.S. Patent Application No. 101369,444, entitled Chair Seat With Firm But Resilient Front Edge, filed on February 19, 2003, which is herein incorporated by reference in its entirety.
The section of fabric 12 of the seat portion 18 is placed in tension by initially inserting the rigid edge portions 38 into the slots 36 of the rigid seat members 14 and 16. In one example of the method of construction of the present invention, rigid seat members 14 and 16-each have two sets of apertures 46 and 47 with one set of aperture positioned near the front crossbrace and one set of apertures positioned near the rear crossbrace, as best illustrated in Figures 2and4.
The apertures 46 and 47 are engaged by spreader tools 48 and 50.
Referring to Figure 4, the spreader tool 50 is illustrated with respect to the fabric 12, and in relation to the front crossbrace 25. Both spreader tools 48 and 50 ate essentially the same, and therefore only spreader tool 50 will be described.
The spreader tool 50 includes a pneumatic or hydraulic cylinder 52 which provides a force to move the seat members 14 and 16 in the direction of arrows 54. The spreader tool 50 at each end includes pins 56 and 58 which engage apertures 46 and 47 of the rigid seat members 14 and 16, respectively. Each pin 56 and 58 engages both the apertures 46 and 47 to prevent the seat members 14 and 16 from rotating about their axis when the section of fabric is placed in tension.
Both spreader tools 48 and 50 are used to move the seat members 14 and 16 away from each other to place the section of fabric 12 in tension.
To retain the seat members 14 and 16 in position on the frame 20, the front crossbrace 25 includes retainer tabs 64 and 66. Similarly, the rear crossbrace 27 includes similar retainer tabs, only one of which is shown (68).
The retainer tabs of the front and rear crossbraces are positioned from each other at a distance which matches a selected distance which seat members 14 and 16 are to be spread apart for the selected tension of the section of fabric 12.
The spreader tools 48 and 50 spread the seat members 14 and 16 sufficiently far enough so that inside faces 60 and 62 of the seat members 14 and 16 extend beyond the retaining tabs 64 and 66. The retaining tabs are preferably permanently secwed to the respective crossbraces such as by welding.
Once the seat members 14 and 16 are positioned beyond the retaining tabs of the front and rear crossbraces, the spreader tools 48 and SO
may be drawn in and the pins disengaged from apertures 46 and 47. Just prior to the disengagement of the spreader tools or directly thereafter, the seat members and 16 are secured to the retaining tabs by screws 70 and 72 which extend through apertures 74 and 75 and into the seat members 14 and 16. The seat members 14 and 16 are similarly attached to the retaining tabs of the rear crossbrace 27. The screws 70 and 72 are exemplary of fasteners that may be used to secure the seat members 14 and 16 in position. Other fasteners or other fastening systems such as adhesives or welding are included within the present invention. Detachable fasteners such as screws have the advantage that the section of fabric may be easily replaced by detaching the seat members 14 and . 16 from the frame 20.
The back portion 34 is similarly constructed. The back portion 34 is also made of a section of fabric 76 that is in tension between back rigid members 78 and 80, as best illustrated in Figure 1. The back members 78 and 80 are similar in construction and have the same cross-section as the seat members 14 and 16 illustrated in Figure 3. The section of fabric 76 also includes rigid end portions similar to the edge portions of fabric 12 that are placed within the slots of the back members 78 and 80. The section of fabric is also placed into tension in a similar manner using spreader tools 48 and 50.
The back members 78 and 80 are spread sufficiently far apart to extend beyond retaining tabs 82 and 80 that extend from the rear crossbrace 27 and retaining tabs 84 and 85 which extend from arm sections 30 and 32 that extend behind the back portion 34 of the chair. The retaining tabs are preferably fixedly attached to the crossbrace and arm sections such as by welding.
Once the back members 78 and 80 are moved beyond the retaining tabs 81, 84 and 82, 85, the back members 78 and 80 are attached to the 2$ retaining tabs, and the spreader tools are disengaged from the back members and 80. Screws (not illustrated) are used in the same manner as screws 70 and 72 to attach the back members 78 and 80 to the retaining tabs 81, 82, 84 and 85.
Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.

The chair construction 10 includes a framework 20 that can be made of plastic, aluminum or steel. The framework includes legs 22, 24, 26 and 28. A front crossbrace 25 and a rear crossbrace 27 extend between and connect the legs 26 and 28 and the legs 22 and 24, respectively. In the embodiment illustrated, the legs 26 and 28 have upper portions 30 and 32 which ~ serve as arms and which are integrally conjoined behind the back portion 34. The particular construction of the framework 20 is not especially important to the present invention, and is described herein as one-exemplary type of framework for which the present invention is suitable.
To form the seat portion 18, the rigid seat members 14 and 16 are provided with a downwardly facing slot 36 as best illustrated in Figures 2 and 3.
The slot 36 runs the length of the rigid members. The section of fabric 12 includes a semi-rigid or rigid edge portion 38 that extends along the length of opposing edge portions. The fabric section 12 overlies the seat member 16 along an outwardly facing side 31 adjacent to the slot 36 and extends over an upwardly facing side 41, as illustrated in Figure 3. Although only the seat member 16 is specifically illustrated in Figure 3, the seat member 14 is similar as a mirror image in both construction and how the fabric section 12 overlies the seat member 14.
-The semi-rigid or rigid edge portion 3$ is sufficiently rigid to secure the section of fabric 12 xo the seat member 16 by engagement with the slot 36.

The section of fabric 12 of the seat portion 18 is placed in tension by initially inserting the rigid edge portions 38 into the slots 36 of the rigid seat members 14 and 16. In one example of the method of construction of the present invention, rigid seat members 14 and 16-each have two sets of apertures 46 and 47 with one set of aperture positioned near the front crossbrace and one set of apertures positioned near the rear crossbrace, as best illustrated in Figures 2and4.
The apertures 46 and 47 are engaged by spreader tools 48 and 50.
Referring to Figure 4, the spreader tool 50 is illustrated with respect to the fabric 12, and in relation to the front crossbrace 25. Both spreader tools 48 and 50 ate essentially the same, and therefore only spreader tool 50 will be described.

The back portion 34 is similarly constructed. The back portion 34 is also made of a section of fabric 76 that is in tension between back rigid members 78 and 80, as best illustrated in Figure 1. The back members 78 and 80 are similar in construction and have the same cross-section as the seat members 14 and 16 illustrated in Figure 3. The section of fabric 76 also includes rigid end portions similar to the edge portions of fabric 12 that are placed within the slots of the back members 78 and 80. The section of fabric is also placed into tension in a similar manner using spreader tools 48 and 50.
The back members 78 and 80 are spread sufficiently far apart to extend beyond retaining tabs 82 and 80 that extend from the rear crossbrace 27 and retaining tabs 84 and 85 which extend from arm sections 30 and 32 that extend behind the back portion 34 of the chair.
