60/002,218, filed August 11, 1995.
BACKÇROUND OF THE INVENTION
Technical Field The invention relates generally to furniture, and more particularly to the attachment of cloth to a f urniture f rame .
Related Prior Art It is generally known to attach webs or straps of fabric to a plastic or metal chair frame in order to provide a support surface, i.e., a seat or backrest.
U.S. Patent 4,552,405 discloses an example of such a structure including means for attaching the fabric to the chair frame.
Various other arrangements for attaching fabric or upholstery to a furniture frame are also known.
SUMMARY OF TH~ INVENTION
One of the disadvantages of known chairs including a chair frame and fabric support surface is that the fabric is permanently fixed to the chair frame. When the fabric is permanently fixed to the chair frame, cleaning and maintenance of the fabric is made more difficult. Also, permanent attachment of the fabric to the chair frame precludes the possibility of replacing the fabric with a 8ubstitute piece of material.
Nevertheless, it is imperative that the fabric be securely attached to the chair frame to assure the integrity of the support surfaces.
Accordingly, the invention provides a chair including a chair frame, a web of fabric and means for releasably fastening the web to the frame. More particularly, in one embodiment, the invention provides a chair assembly comprising a frame including a channel 2~ 8~'a42 and a resiliently deflectable wall, a retalner received by the channel and removably secured in the channel by the deflectable wall, and a web of fabric located in the channel and engaged with the retainer and the frame, whereby the web is releasably fixed to the frame.
In another embodiment, the invention provides a chair assembly comprising a frame, a web of fabric, and means for releasably attaching the web to the frame, the means including, on the frame, a fixed wall and a deflectable wall spaced from the fixed wall, the means including a retainer received between and engaged by one of the fixed and deflectable walls and by the web, whereby the retainer is removably secured to the f rame .
The invention provides advantage by affording assembly of the chair, and selective removal of the fabric from the chair frame. Moreover, assembly and disassembly of the chair does not require any tools.
The chair provides a rigid, light weight frame with a removable fabric web that provides a support surface.
The chair thus provides a comfortable, breathable support surface that can be easily replaced or removed for aesthetic or maintenance purposes. Such advantages are not met by chairs made entirely of plastic or by chairs having permanently attached fabric.
In addition, the fabric is releasably fixed to the chair frame along a length of the fabric in a manner minimizing stress concentrations on the fabric, thereby reducing the likelihood of tearing or fraying of the f abric .
Other features and advantages of the invention will become apparent to those skilled in the art upon review of the following detailed description, claims and drawings .

Before one embodiment of the invention is explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
DETAILED DEscRIPTION OF THE PREFERRED EMBODIMENT
The drawings illustrate a chair 10 which embodies the invention, which is preferably made of in~ection molded plastic, and which has a sling-like fabric seat and backrest. Referring first to Figure l, the chair lO
includes a seat frame 14 including four legs 22, two armrests 26 extending between the upper ends of respective pairs of legs 22, and a seat 30 supported by the legs 22.
More specifically, and as best shown in Figure 2, the seat 30 includes a pair of seat frame side members 34 (one shown in Figure 2), a seat frame front member 38 which extends between the forward ends of the seat frame side members 34, and a seat support 42 which extends between the seat frame side members 34 at a position located near the rearward ends of the seat frame side members 34. The seat frame side members 34 are mirror images of each other and, for the purpose of description, the seat frame member 34 shown in Figure 2 will be discussed in detail with the understanding that ` 2 l 83~2 .
the other seat frame side member 3~ is similarly constructed .
The seat 30 also includes a web of seat fabric 44 which is attached to the seat frame side members 34 and the seat frame front member 38 in a manner discussed in detail below. The seat fabric 44 is generally rectangular and, as best shown in Figure 2, the seat fabric has a cut-out portions 46 such that the seat fabric 44 has a pair of edges 44a which can be attached to respective seat frame side members 34 and an edge 44b which can be wrapped over and attached to the seat frame front member 38. For reasons discussed below, and as best shown in Figures 4-6, the edges 44a, 44b of the seat fabric 44 each include a welting 47. The welting 47 is formed by a sleeve of fabric and a core or bead of relatively incompresslble material, such as metal or an extruded plastic rod, which is enclosed by the sleeve.
The chair 10 also includes a backrest 48. The backrest 48 includes a pair of backrest side members 50, which have respective lower ends 54 ( only one shown in Figures 1 and 2 ) received by respective sockets in the seat frame side members 34 to support the backrest 48 on the seat frame 14. The backrest side members 50 are (Figure 6) generally hollow and define a rearwardly opening cavity which iB closed by a removable backrest cavity cover plate 56. The backrest cavity cover plate 56 is held in position by a series of detents 57 which are located on the backrest side members 50 and which resiliently engage the edges of the backrest cavity cover plate 56 and hold the cover plate 56 in position.
The backrest side members 50 are mirror images of each other and, for the purpose of description, the backrest side member 50 shown in Figure 6 will be discussed in detail with the understanding that the other backrest side member 50 is similarly constructed.
The backrest 48 also includes an upper backrest cross member 58 extending between the upper ends of the backrest side members 50 and a lower backrest cross member (not shown) extending between the backrest side members 50 ad jacent the lower ends thereof.
The backrest 48 also includes a web of backrest fabric 62 which is similar to the web of seat fabric 44 and also includes cut-out portions 63 such that the backrest fabric 62 has opposLte side edges 64a which can be attached to the backrest side members S0 in a manner discussed immediately below, and an upper edge (not shown ) which can be wrapped around and attached to the upper backrest cross member 58.
The chair lO also includes means 70 for attaching the webs of fabric 44, 62 to the frame members of the seat frame 14 and backrest 48. While various suitable constructions can be successfully used, in the illustrated embodiment, such attachment means 70 includes a channel 74 formed in the seat frame side members 3 4 .
The channel 74 extends along the length of the seat frame side member 34, has opposite forward and rearward ends and opens upwardly. As best shown in Figure 4, the channel 74 is defined by a pair of sidewalls 78 and 80 which are, in general, relatively rigid, and which are connected by a bottom wall 82. More particularly, the sidewall 78 is a fixed wall 78. Along the length of the channel 74, the sidewall 80 has cut out portions which define deflectable wall portions 86. The deflectable wall portions 86 are resiliently movable between a first position (shown in Figure 4) and a second, retracted position ( shown in phantom in Figure 4 ) wherein the edge 90 and detent 94 of the deflectable wall portion 86 are moved away from the fixed wall portion 78.
The attachment means 70 also includes a retainer strip 98 which can be received by the channel 74 and engaged by the detent 94. As best shown in Figure 4, the retainer strip 98 has a u-shaped or c-shaped cross section and a length approximating the length of the channel 74. The u-shaped cross section of the retainer strip 98 is provided by a first or upper sidewall 102 which provides an surface 106 that faces outwardly of the u-shaped cross-section and which, when the retainer 2 1 830~2 strip is received by the channel 74, is exposed. The retainer strip 98 also includes a second or lower sidewall or locking wall 110 which provides an engagement surface 114 that faces inwardly of the u-shaped cross section. The retainer strip 98 also includes a connecting wall 118 extending between the first and second sidewalls 102, 110.
The retainer strip is engageable with the def lectable wall portion 86 80 as to be locked into place and, when the fabric 44 is placed in the channel 74, the retaining strip engages the fabric and holds it in position against the fixed wall 78 of the seat frame side member 34 through engagement of the locking wall 110 with the welting 47.
More particularly, the fabric 44 can be attached to the seat frame 14 as follows: First, the side portion and edge 44a of the seat fabric 44 is wrapped over the upper surface of the frame side member 34 and the welting 47 is placed into the channel 74 so that the edge 44a of the seat fabric 44 is adjacent the bottom wall 82. Once the fabric is 80 positioned, the retainer strip 98 can be inserted into the channel 74 and pressed down into engagement with the deflectable wall portions 86. When 80 engaged, the engagement surface 114 on the locking wall 110 of the retainer strip 98 engages the lower surface of the detent 94 to hold the retainer strip 98 in position. Also when the retainer strip 98 is so received by the channel 74, the exposed wall 102 is preferably substantially flush with the upper surface of the seat frame side member 34.
In the event that the fabric 44 needs to be removed from the seat 30, the attachment means 70 can be released so that the edge 44a of the fabric 44 is no longer clamped between the retainer strip 9 8 and the frame member 34. More particularly, the attachment means 70 can be released by moving the lower edge 90 of each deflectable wall 86 away from the fixed wall 78 80 as to move the detent 94 out of engagement with the surface 114 of the locking wall 110. When each moveable wall 86 is 80 deflected, the retainer strip 98 can be removed from the channel 74 to thereby release the edge 44a of the seat fabric 44.
The attachment means 70 also includes means on the seat frame front member 38 for engaging the seat fabric 44. As best shown in Figure 5, the arrangement on the seat frame front member 38 for attaching the fabric 44 to the seat frame 14 is substantially similar to that of the seat frame side members 34, with slight dif ferences .
The most significant difference in the construction of the seat frame front member 38 is the provision of a deflectable wall 122 which provides a detent 126 located at the edge of the deflectable wall 122 rather than spaced away from the edge. The deflectable wall 122, particularly the detent 126, is engageable with a retainer strip 98 which is received in a channel 74 (which faces downwardly in the seat frame front member 38 ) . The side portion including edge 44b of the seat fabric 44 is wrapped over the upper surface of the seat frame front member 38 and the edge 44b and welting 47 is placed into the channel 74 so that the edge 44b is positioned adjacent upper edge of the fixed wall 78.
Once the fabric is so positioned, the retainer strip 98 can be inserted into the channel 74 and pressed into engagement with the detent 126.
The welting 47 is thus captured between the retainer strip 98 and the fixed wall 78 of the seat frame front member 38, and the fabric is attached to the seat frame front member 38. Like the deflectable wall 86 in the seat frame side member, the deflectable wall 122 on the seat frame front member is mov~ble to release the retainer strip 98 from engagement with the detent 126 and so that the retainer strip 98 can be removed from the channel 74 and to thereby release the edge 44b of the fabric 44.
The attachment means 70 also includes similar structure on the backrest side members 50. In particular, and as best shown in Figure 6, the backrest side members 50 define rearwardly opening channels 74 defined by 8 fixed wall 78 and deflectable wall portions 8 6 each having an edge 9 0 and a detent 9 4 . A retainer strip 98 is can be received by the channel 74 to lock the edge of the backrest fabric 62 into the channel 74.
rn the event that the backrest fabric 62 needs to be removed, access to the attachment means 70 on the backrest 48 can be gained by removing the backrest cavity cover plate 56. Each deflectable wall portion 86 can then be moved to its second position ( not shown in Figure 6 ) to release the detent 94 from engagement with the engagement surface 114, thereby permitting the retainer 6trip to be removed from the channel 74 and releasing the backrest fabric 62.
The upper edge of the backrest fabric 64 is secured to the backrest cross member 58 in a manner substantially identical to that in which the edge 44b of the seat fabric 44 is secured to the seat cross member 38 .
Various features of the invention are set forth in the following claims.

DETAILED DEscRIPTION OF THE PREFERRED EMBODIMENT
The drawings illustrate a chair 10 which embodies the invention, which is preferably made of in~ection molded plastic, and which has a sling-like fabric seat and backrest. Referring first to Figure l, the chair lO
includes a seat frame 14 including four legs 22, two armrests 26 extending between the upper ends of respective pairs of legs 22, and a seat 30 supported by the legs 22.
More specifically, and as best shown in Figure 2, the seat 30 includes a pair of seat frame side members 34 (one shown in Figure 2), a seat frame front member 38 which extends between the forward ends of the seat frame side members 34, and a seat support 42 which extends between the seat frame side members 34 at a position located near the rearward ends of the seat frame side members 34. The seat frame side members 34 are mirror images of each other and, for the purpose of description, the seat frame member 34 shown in Figure 2 will be discussed in detail with the understanding that ` 2 l 83~2 .
the other seat frame side member 3~ is similarly constructed .
The seat 30 also includes a web of seat fabric 44 which is attached to the seat frame side members 34 and the seat frame front member 38 in a manner discussed in detail below. The seat fabric 44 is generally rectangular and, as best shown in Figure 2, the seat fabric has a cut-out portions 46 such that the seat fabric 44 has a pair of edges 44a which can be attached to respective seat frame side members 34 and an edge 44b which can be wrapped over and attached to the seat frame front member 38. For reasons discussed below, and as best shown in Figures 4-6, the edges 44a, 44b of the seat fabric 44 each include a welting 47. The welting 47 is formed by a sleeve of fabric and a core or bead of relatively incompresslble material, such as metal or an extruded plastic rod, which is enclosed by the sleeve.
The chair 10 also includes a backrest 48. The backrest 48 includes a pair of backrest side members 50, which have respective lower ends 54 ( only one shown in Figures 1 and 2 ) received by respective sockets in the seat frame side members 34 to support the backrest 48 on the seat frame 14. The backrest side members 50 are (Figure 6) generally hollow and define a rearwardly opening cavity which iB closed by a removable backrest cavity cover plate 56. The backrest cavity cover plate 56 is held in position by a series of detents 57 which are located on the backrest side members 50 and which resiliently engage the edges of the backrest cavity cover plate 56 and hold the cover plate 56 in position.
The backrest side members 50 are mirror images of each other and, for the purpose of description, the backrest side member 50 shown in Figure 6 will be discussed in detail with the understanding that the other backrest side member 50 is similarly constructed.
The backrest 48 also includes an upper backrest cross member 58 extending between the upper ends of the backrest side members 50 and a lower backrest cross member (not shown) extending between the backrest side members 50 ad jacent the lower ends thereof.
The backrest 48 also includes a web of backrest fabric 62 which is similar to the web of seat fabric 44 and also includes cut-out portions 63 such that the backrest fabric 62 has opposLte side edges 64a which can be attached to the backrest side members S0 in a manner discussed immediately below, and an upper edge (not shown ) which can be wrapped around and attached to the upper backrest cross member 58.
The chair lO also includes means 70 for attaching the webs of fabric 44, 62 to the frame members of the seat frame 14 and backrest 48. While various suitable constructions can be successfully used, in the illustrated embodiment, such attachment means 70 includes a channel 74 formed in the seat frame side members 3 4 .
The channel 74 extends along the length of the seat frame side member 34, has opposite forward and rearward ends and opens upwardly. As best shown in Figure 4, the channel 74 is defined by a pair of sidewalls 78 and 80 which are, in general, relatively rigid, and which are connected by a bottom wall 82. More particularly, the sidewall 78 is a fixed wall 78. Along the length of the channel 74, the sidewall 80 has cut out portions which define deflectable wall portions 86. The deflectable wall portions 86 are resiliently movable between a first position (shown in Figure 4) and a second, retracted position ( shown in phantom in Figure 4 ) wherein the edge 90 and detent 94 of the deflectable wall portion 86 are moved away from the fixed wall portion 78.
The attachment means 70 also includes a retainer strip 98 which can be received by the channel 74 and engaged by the detent 94. As best shown in Figure 4, the retainer strip 98 has a u-shaped or c-shaped cross section and a length approximating the length of the channel 74. The u-shaped cross section of the retainer strip 98 is provided by a first or upper sidewall 102 which provides an surface 106 that faces outwardly of the u-shaped cross-section and which, when the retainer 2 1 830~2 strip is received by the channel 74, is exposed. The retainer strip 98 also includes a second or lower sidewall or locking wall 110 which provides an engagement surface 114 that faces inwardly of the u-shaped cross section. The retainer strip 98 also includes a connecting wall 118 extending between the first and second sidewalls 102, 110.
The retainer strip is engageable with the def lectable wall portion 86 80 as to be locked into place and, when the fabric 44 is placed in the channel 74, the retaining strip engages the fabric and holds it in position against the fixed wall 78 of the seat frame side member 34 through engagement of the locking wall 110 with the welting 47.
More particularly, the fabric 44 can be attached to the seat frame 14 as follows: First, the side portion and edge 44a of the seat fabric 44 is wrapped over the upper surface of the frame side member 34 and the welting 47 is placed into the channel 74 so that the edge 44a of the seat fabric 44 is adjacent the bottom wall 82. Once the fabric is 80 positioned, the retainer strip 98 can be inserted into the channel 74 and pressed down into engagement with the deflectable wall portions 86. When 80 engaged, the engagement surface 114 on the locking wall 110 of the retainer strip 98 engages the lower surface of the detent 94 to hold the retainer strip 98 in position. Also when the retainer strip 98 is so received by the channel 74, the exposed wall 102 is preferably substantially flush with the upper surface of the seat frame side member 34.
In the event that the fabric 44 needs to be removed from the seat 30, the attachment means 70 can be released so that the edge 44a of the fabric 44 is no longer clamped between the retainer strip 9 8 and the frame member 34. More particularly, the attachment means 70 can be released by moving the lower edge 90 of each deflectable wall 86 away from the fixed wall 78 80 as to move the detent 94 out of engagement with the surface 114 of the locking wall 110. When each moveable wall 86 is 80 deflected, the retainer strip 98 can be removed from the channel 74 to thereby release the edge 44a of the seat fabric 44.
The attachment means 70 also includes means on the seat frame front member 38 for engaging the seat fabric 44. As best shown in Figure 5, the arrangement on the seat frame front member 38 for attaching the fabric 44 to the seat frame 14 is substantially similar to that of the seat frame side members 34, with slight dif ferences .
The most significant difference in the construction of the seat frame front member 38 is the provision of a deflectable wall 122 which provides a detent 126 located at the edge of the deflectable wall 122 rather than spaced away from the edge. The deflectable wall 122, particularly the detent 126, is engageable with a retainer strip 98 which is received in a channel 74 (which faces downwardly in the seat frame front member 38 ) . The side portion including edge 44b of the seat fabric 44 is wrapped over the upper surface of the seat frame front member 38 and the edge 44b and welting 47 is placed into the channel 74 so that the edge 44b is positioned adjacent upper edge of the fixed wall 78.
Once the fabric is so positioned, the retainer strip 98 can be inserted into the channel 74 and pressed into engagement with the detent 126.
The welting 47 is thus captured between the retainer strip 98 and the fixed wall 78 of the seat frame front member 38, and the fabric is attached to the seat frame front member 38. Like the deflectable wall 86 in the seat frame side member, the deflectable wall 122 on the seat frame front member is mov~ble to release the retainer strip 98 from engagement with the detent 126 and so that the retainer strip 98 can be removed from the channel 74 and to thereby release the edge 44b of the fabric 44.
The attachment means 70 also includes similar structure on the backrest side members 50. In particular, and as best shown in Figure 6, the backrest side members 50 define rearwardly opening channels 74 defined by 8 fixed wall 78 and deflectable wall portions 8 6 each having an edge 9 0 and a detent 9 4 . A retainer strip 98 is can be received by the channel 74 to lock the edge of the backrest fabric 62 into the channel 74.
rn the event that the backrest fabric 62 needs to be removed, access to the attachment means 70 on the backrest 48 can be gained by removing the backrest cavity cover plate 56. Each deflectable wall portion 86 can then be moved to its second position ( not shown in Figure 6 ) to release the detent 94 from engagement with the engagement surface 114, thereby permitting the retainer 6trip to be removed from the channel 74 and releasing the backrest fabric 62.
The upper edge of the backrest fabric 64 is secured to the backrest cross member 58 in a manner substantially identical to that in which the edge 44b of the seat fabric 44 is secured to the seat cross member 38 .
Various features of the invention are set forth in the following claims.
