The polyester layer provides a pad area for association with the buttocks of a cycling individual, two side pad areas for association with the upper inside thighs of the individual, and a pad area for association with the lower abdominal area of the individual. A thin and low hardness synthetic foam layer has a shape that complements the polyester layer, and a bottom surface thereof engages a top surface of the polyester layer. A thick, high hardness, synthetic foam layer is associated with the thin foam layer and occupies the pad area association with the buttocks. A synthetic leather layer has a shape that complements the shape of the polyester layer and a bottom surface thereof engages the top surface of the thin foam layer and the top surface of the thick foam layer.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to the field of garments to be worn by humans, and, more specifically, to a chamois for use within cycling pants or shorts to be worn by a male or a female while operating a bicycle. 
     2. Description of Related Art 
     Cycling pants/shorts of various configurations have become popular because they provide durability, they provide cushioning between the bicycle seat and the cyclist, and they minimize chafing of the body of the cyclist. Cycling pants conventionally include an inner pad that is located within the crotch and buttocks regions of the cyclist. Such pads have become known as chamois. While some chamois are composed of a number of pieces of flexible material that are stitched together, other chamois are formed of one piece of material. 
     For example, U.S. Pat. No. 4,961,233 (incorporated herein by reference) provides a two-layer, one-piece, heat-formed, and seamless chamois that includes an inner liner that faces the body of the cyclist and is made of a synthetic leather-like material, such as the brand Ultrasuede, and an outer synthetic fleece (polyester) member that is compressible. The inner liner and the synthetic fleece are adhesive bonded. The chamois is heat-formed to impart a generally form-fitting shape to the chamois wherein the edges of the chamois are over edge stitched. U.S. Design Patent DES. 360,971 also appears to be directed to the above anatomical seat pad. 
     U.S. Pat. No. 5,271,101 (incorporated herein by reference) provides cycling shorts that include a padded, three-layer, seat liner having a plurality of integrally formed and embossed break lines that create seamless indentations in the liner. These break lines are positioned such that the liner conforms to the anatomical profile of a cyclist who is positioned in a riding position on a bicycle. The liner is stitched or laminated to a body portion of the cycling pants. The liner includes a nylon tricot backing layer, a high-density polyurethane foam layer having open or closed cells that overlies the backing layer, and a synthetic suede covering layer that overlies the foam layer. The synthetic suede has a soft-napped side that faces the cyclist body. The embossed break lines are located in positions that represent pressure crease point of the seat liner when a cyclist is in a cycling position, and as the cyclist moves to other positions so as to prevent the bunching of excess material. The embossed break lines are formed without using stitching or sewn seams by heat molding the seat liner in a flat position. 
     U.S. Pat. No. 4,805,243 (incorporated herein by reference) describes bicycle shorts having openable pockets that removably receive seat and crotch synthetic foam pads having different thickness, thus adapting the padding to suit individual preferences. 
     U.S. Pat. No. 4,945,571 (incorporated herein by reference) provides bicycling shorts having a liquid-filled cushion for cushioning the rider thighs and buttocks, the cushion having a plurality of layers of material to facilitate perspiration wickage. The liquid cushions include overlying layers of a polyurethane material and water, non-freezable silicon or glycerin or mixtures thereof, oils or other slippery material. 
     While the art provides various type of cycling garments, as exemplified above, the need remains in the art for chamois and cycling garments that provide additional and improved benefits to the wearer as a bicycle is operated. 
     SUMMARY OF THE INVENTION 
     In embodiments of the present invention, a cycling chamois is provided that is formed of a number of flexible sheets or pieces of fabric or fabric and/or synthetic leather, and that includes strategically located pieces of relatively low-hardness foam and relatively high-hardness foam. 
     Chamois in accordance with the present invention provide support for the pelvic girdle of a male or a female cyclist. As is well known, the pelvic girdle (also known as the bony pelvis) is a basin-shaped complex of bones that connect the trunk and legs, that supports and balances the trunk, and that contains and supports the intestines, the urinary bladder, and the internal sex organs. The pelvic girdle includes paired hipbones that are connected in the front by the pubic symphysis and at the back by the sacrum, and includes the ischium on which weight falls in sitting wherein the ischial tuberosity is called the sitting bone. 
     When chamois constructed and arranged in accordance with the present invention is attached to the inside of a cycling garment, and when the garment is then worn by a cyclist, a garment-side of the chamois that faces the garment, and a body-side of the garment faces the cyclist body. In the following discussion, the side of the chamois that faces the garment will be called the bottom side or the garment-facing side of the chamois, and the side of the chamois that faces the cyclist body will be called the top side or the body-facing side of the chamois. 
     This invention provides embodiments of chamois wherein two pieces of relatively high-hardness foam are strategically located to accommodate the pelvic girdle of a male cyclist, and the invention provides other embodiments of the invention wherein one piece of relatively high-harness foam is strategically located to accommodate the pelvic girdle of a female cyclist. 
     More specifically, male-use chamois in accordance with the invention provide two physically-spaced pieces of relatively high-hardness foam that support the two buttocks of a male cyclist, while leaving a crotch space therebetween that is occupied by relatively low-hardness foam, whereas female-use chamois in accordance with the invention provides one piece of relatively high-hardness foam that supports both the buttocks and the crotch of a female cyclist. 
     Both a male-use chamois and a female-use chamois in accordance with the invention include a garment-facing cloth or cloth-like member whose outline forms the generally flat external shape or profile of the chamois. This garment-facing cloth member is adapted to physically engage the inner surface of a garment to be worn by a male/female cyclist. 
     This garment-facing cloth can be a woven cloth or a non-woven cloth, and it can be formed of a natural material or of a synthetic material, with polyester scrim being preferred, or with a non-woven interfacing or batting that is constructed of polyester fibers being preferred. 
     In use, this garment-facing cloth member is usually sewn to the inside of the seat area of a cycling garment. 
     Both a male-use chamois and a female-use chamois in accordance with the invention include a layer of relatively low-hardness foam whose outline forms the external shape or profile of the chamois. 
     In an embodiment of a male-use chamois in accordance with the invention, this layer of relatively low-hardness foam contains two buttocks-region holes that are filled by two pieces of relatively high-hardness foam. In another embodiment of a male-use chamois in accordance with the invention, this layer of relatively low-hardness foam is a continuous layer, and two physically-spaced pieces of relatively high-hardness foam overly two physically-spaced spaced buttocks regions on the layer of relatively low-hardness foam. 
     In an embodiment of a female-use chamois in accordance with the invention, this layer of relatively low-hardness foam contains one buttocks/crotch-region hole that is filled by one piece of relatively high-hardness foam. In another embodiment of a female-use chamois in accordance with the invention, this layer of relatively low-hardness foam is a continuous layer, and one piece of relatively high-hardness foam overlies the buttocks/crotch-region on the layer of relatively low-hardness foam. 
     As used herein, the term foam means a flexible, porous, natural or synthetic material whose volume contains a relatively high percentage of open or closed cells, and a relatively low percentage of the natural or synthetic material from which the foam is formed. While the spirit and scope of the invention is not to be limited thereto, in an embodiment of the invention, the low-hardness foam had a hardness of about 20 durometer (20 d) as measured by a durometer, and the relatively high-hardness foam had a hardness from about 40 d to about 90 d. 
     The term foam, as used herein, is also intended to mean a foamed or expanded plastic material that has been treated so as to cause air or gas bubbles or cells to be formed therein, these cells being either closed cells or open cells. However, within the spirit and scope of the invention, the term foam includes both presently known and after-developed equivalent means, such as gel-filled members and/or liquid-filled members. A non-limiting example is an open-cell polyurethane foam. 
     Both a male-use chamois and a female-use chamois in accordance with the invention include a garment-facing cloth or cloth-like member outline forms the external shape or profile of the chamois. 
     In an embodiment of a male-use chamois in accordance with the invention, this garment-facing cloth member is a continuous member. In another embodiment of a male-use chamois in accordance with the invention, this garment-facing cloth member contains two buttocks-region holes that are filled by two pieces of synthetic leather. In another embodiment of a male-use chamois in accordance with the invention, this garment-facing member is a continuous member, and two physically-spaced pieces of synthetic leather overly two physically-spaced buttocks regions on the body-facing cloth member. 
     In an embodiment of a female-use chamois in accordance with the invention, this garment-facing cloth member is a continuous member. In another embodiment of a female-use chamois in accordance with the invention, this garment-facing cloth member contains one buttocks/crotch-region hole that is filled by one piece of synthetic leather. In another embodiment of a female-use chamois in accordance with the invention, this garment-facing member is a continuous member, and one piece of synthetic leather overlies the buttocks/crotch-region on the body-facing cloth member. 
     This body-facing member can be a woven cloth or a non-woven cloth, and it can be formed of a natural material or of a synthetic material, with warp knit polyester tricot having a wicking finish being preferred. 
     In embodiments of the invention, a unitary chamois is formed of the various members by providing a heat-melting plastic ribbon the extends along the edges or boarders of the various member, such that the use of a heat press operates to melt the plastic ribbon and form a unitary chamois from the various chamois members. 
     As a feature of the invention, the chamois in accordance with this invention is formed into a single unit by the use of a bonding agent, and/or by the application of heat and pressure that operates to fuse the various pieces of the chamois together into a single unit. 
     As a feature of the invention, the application of heat and pressure to the chamois in accordance with this invention operates to form the chamois into a three-dimensional shape that generally matches the pelvic girdle of a male or a female. 
     While the invention will be described while making reference to the use of foam sheets, which may include open cell and/or closed-cell foams, the spirit and scope of the invention includes the use of both existing equivalent members and after-developed equivalent foam members. Examples of existing and equivalent foam members include, but are not limited to, gel-filled foam members, liquid-filled foam members, air-filled foam members, and combinations thereof, preferably to replace the above-descried thick foam sheets, but also to replace the above-described thin foam sheet.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention provides both male-use and female-use chamois for use within cycling garments in order to improve the comfort and the protection to the body of a male/female operating a bicycle. 
     FIG. 1 is a body-side view (i.e., the side of the chamois that faces the cyclist body) of a chamois  10  in accordance with the invention wherein chamois  10  is constructed and arranged for use by a male cyclist. 
     Chamois  10  is symmetrical about a front-to-back centerline  11 , the forward end of chamois  10  being indicated by numeral  12 , and the rearward end of chamois  10  being indicated by numeral  13 . 
     Chamois  10  includes two relatively thick and high-hardness foam pad areas  14  and  15  that are established by two relatively high-hardness and generally tear-drop shaped pieces of foam  16  and  17  (see FIG. 6) that are contained within chamois  10 . Teardrop shaped thick pad area  14  is adapted to support the right buttocks of a male cyclist, and teardrop shaped thick pad  15  is adapted to support the left buttocks of a male cyclist. 
     By way of a non-limiting example, relatively thick pad areas  14  and  15  are about 10 mm to about 14 mm thick, preferably about 12 mm thick, and they are formed of a relatively high density, polyester-based, expanded polyurethane foam having a hardness in the range of from about 40 durometer (40 d) to about 90 d, as measured by a durometer instrument. 
     In the art, normal density, polyester-based, expanded polyurethane foam is known to have a density of about 20 d, whereas relatively high density, polyester-based, expanded polyurethane foam has a hardness in the range of from about 40 d to about 90 d. 
     The term cloth or cloth-like member or sheet as used herein is intended to mean a pliant sheet material that is usually made by weaving, felting, or knitting natural or synthetic fibers and/or filaments. 
     While the term synthetic leather will be used in describing embodiments of the invention, it is intended that the use of a more expensive natural leather, rather than a synthetic material that is fabricated so as to imitate natural leather, is also encompassed by this term. 
     All chamois areas with the exception of thick pad areas  14  and  15  are formed by a sheet of relatively thin foam having a relatively low hardness. By way of a non-limiting example, these other pad areas are about 4 mm to about 8 mm thick, preferably about 6 mm thick, and the relatively thin foam that forms these other pad areas is expanded, polyester-based, polyurethane foam having a harness of about 20 d. 
     These other relatively thin and low-hardness chamois pad areas include a relatively narrow, forward tapered, and centrally-located thin foam pad  20  that generally corresponds to the crotch area of a male cyclist, a right side upper interior thigh pad  21 , a left side upper interior thigh pad  22 , a forward lower abdominal pad  23 , and two rear pads  26  and  27  that generally surround the rear of thick and high-hardness form pads  14  and  15 . 
     The various foam pad areas  14 ,  15 ,  20 ,  21 ,  22 ,  23 ,  26 , and  27  of chamois  10  are surrounded or outlined by thin heat-formed lines  24  that are about 2 mm thick. 
     FIG. 2 is a garment-side view of chamois  10  (i.e., the side of chamois  10  that faces a cycling garment), this figure also showing the optional use of stitching  25  along the forward edge of chamois  10  and along the edges of the chamois&#39; thigh portions. 
     FIGS. 6,  7  and  8  are section views of male-use chamois  10  that are taken along the lines  6 — 6 ,  7 — 7  and  8 — 8  of FIG.  1 . These three figures perhaps best show the relative thickness of the chamois&#39; various foam pads and heat-formed line areas  24 . 
     FIG. 3 is a body-side view of a chamois  30  in accordance with the invention that is constructed and arranged for use by a male cyclist. Chamois  30  is similar to above-described chamois  10 , with the exception that an additional lower-abdominal pad  31  has been stitched or heat attached to the forward edge  32  chamois  30 . Pad  31  contains a sheet of relatively thin and low-hardness foam, as was described above relative to pads  21 ,  22 ,  23 ,  26  and  27 . 
     FIG. 4 is a garment-side view of FIG. 3 chamois  30 , this figure showing that pad  31  has been stitched at  33  to the forward end  32  of chamois  30 . 
     FIGS. 6,  7  and  8  are section views of chamois  30  that are taken along the lines of  6 — 6 ,  7 — 7  and  8 — 8  of FIG.  3 . These three figures perhaps best show the relative thickness of the chamois&#39; various foam pads and heat-formed line areas  24 . 
     FIG. 5 is a view similar to FIGS. 3 and 4 that is useful in identifying exemplary and non-limiting physical dimensions of portions of chamois  30 , these dimensions being typical of a chamois  10  or  30  in accordance with the invention that are for use by a male cyclist. 
     FIG. 15 is an exploded side view of a portion of a male-use chamois  10  and  30  in accordance with the invention, this figure showing how the chamois is assembled from five pieces that include a garment-facing cloth member  35 , a sheet  36  of relatively thin and low-hardness foam that has the same outer shape as garment-side cloth member  35 , and that has two through-holes  37  and  38  cut therein in order to form two holes  37 ,  38  that complement the outer shape of two pieces  39  and  40  of thick and high-hardness foam, each piece  39 ,  40  of thick foam closely fitting within a through-hole  37 ,  38  that is formed in thin foam sheet  36 , and a body-facing cloth member  41 . 
     As a feature of the invention, body-facing cloth member  41  is formed of a synthetic leather (for example, of the brand ALCANTARA), garment-facing cloth member  35  is formed of a polyester, preferably a wicking polyester, thin foam layer  36  is about 6 mm thick and has a hardness of about 20 d, and each of the two thick foam pieces  39 ,  40  is about 12 mm thick and has a hardness in the range of from about 40 d to about 90 d. 
     FIG. 17 shows another embodiment of the invention wherein a male-use chamois  45  comprises seven pieces that include a body-facing cloth member  41  that is formed of a wicking polyester, and includes two generally tear-drop shaped through-holes  47  and  48  that are formed therein so as to directly overly two generally tear-drop shaped through-holes  37  and  38  that are formed in a thin and low-hardness foam layer  36 . Each of the two through-holes  47 ,  48  within body-facing cloth member  41  are then filled by a piece of similarly shaped and similar thickness synthetic leather  79 ,  80  that individually directly overlie one of the two pieces  39 ,  40  of thick foam. 
     FIG. 19 shows another embodiment of the invention wherein a male-use chamois  81  comprises seven pieces that include a continuous garment-facing cloth member  35 , a continuous low-hardness foam layer  36 , a continuous body-facing cloth member  41  that is preferably formed of a synthetic wicking polyester (i.e., a warp knit polyester tricot with a wicking finish) that includes two generally tear-drop shaped areas  84  and  85  thereon that each receive a piece  39 ,  40  of similarly shaped, thick, and high-harness foam  39  and  40 , with the top surfaces of thick foam pieces each individually receiving a piece of synthetic leather  79 ,  80 . 
     The top and bottom views of chamois  81  are generally identical to FIGS. 1 and 2 with the exception that stitching  25  of FIG. 2 is not provided on chamois  81 . Chamois  81  does, however, include weld lines  24 . 
     FIG. 21 is an exploded view that shows how the weld lines  24  that bind the edges of body-facing cloth member  35 , this foam layer  36 , and garment-facing cloth member  41  are formed by placing thin ribbons  100  of heat-meltable plastic intermediate layers  35  and  36  and intermediate layers  36  and  41 . When the FIG. 21 assembly  35 ,  36 , and  41  is placed within a heat-press, ribbons  100  melt and bind the edges of the assembly together as a thin weld line  24  is formed. 
     This or another heat/pressure process can also be used to form chamois  81  into a three-dimensional shape that approximates the pelvic girdle of a male cyclist. As a result, chamois  81  is devoid of stitching and the like. 
     An important feature of the FIG. 19 embodiment of the invention is that a first large-size sheet can be formed that comprises the three layers  35 ,  36 ,  41 , and a second large-size sheet can be formed that comprises the two layers  39 ,  40  and  79 ,  80 . Preferably, the layers of the first and second multi-layer sheets are bonded together to thereby form two unitary sheets that are relatively easy to handle during manufacture of a chamois in accordance with the invention. 
     The first three-layer sheet can be then stamped or cut to form a plurality of individual three-layer pieces  41 ,  36 ,  35  (FIG. 19) that are each of the overall chamois shape that is shown in FIG.  1 . In addition, the second two-layer sheet can then be stamped, or cut to form a first plurality of tear-drop shaped individual pieces  79 ,  39  (FIG. 19) that are of the thick-pad shape  14  that is shown in FIG. 1, and the second two-layer sheet can also be stamped or cut to form a second plurality of tear-drop shaped individual pieces  80 ,  40  (FIG. 19) that are of the thick pad shape  15  that is shown in FIG.  1 . 
     A single chamois  81  can then be formed by using one of the three-layer chamois-shaped pieces, by using one of the two layer thick pad shapes  14 , and by using one of the two-layer thick-pad-shapes  15 . 
     Turning now to a description of chamois in accordance with the invention that are constructed and arranged for use by a female cyclist, FIG. 9 is a body-side view of a chamois  55  in accordance with the invention wherein chamois  55  is constructed and arranged for use by a female cyclist. Chamois  55  is symmetrical about a front-to-back centerline  56 , the forward end of chamois  55  being indicated by numeral  57 , and the rearward end of chamois  55  being indicated by numeral  58 . 
     Chamois  55  includes one relatively thick and high-hardness foam pad area  59  that is generally of an elongated heart-shape. Thick pad area  59  is provided by a piece of relatively high-hardness foam, as discussed above, that is contained internally of chamois  55 , as shown in FIGS. 11 and 12. Thick pad area  59  is symmetrical about centerline  56  and it is adapted to support the right buttocks, the left buttocks and the crotch area of a female cyclist. 
     Again by way of a non-limiting example, thick pad area  59  is about 12 mm thick, and the thick foam that forms pad area  59  has a durometer of about 40 d to about 90 d. 
     All chamois areas, with the exception of thick pad area  59 , are formed by a sheet of relatively thin and low-hardness foam. By way of a non-limiting example, these other pad areas are about 6 mm thick, and the relatively thin foam that forms these other pad areas has a durometer of about 20 d. 
     These other relatively thin chamois pad areas include a right-side upper inside thigh pad  60 , a left-side upper inside thigh pad  61 , a forward lower-abdominal pad  62 , and two rear pad areas  63  and  64  that generally surround the rear of thick foam pad  59 . 
     The various pad areas  59 ,  60 ,  61 ,  62 ,  63 , and  64  of chamois  55  are outlined or surrounded by thin heat-formed lines  66  that are about 2 mm thick. FIG. 10 is a garment-side view of chamois  55 . 
     FIGS. 11,  12  and  13  are section views of chamois  55  that are taken along the lines  11 — 11 ,  12 — 12  and  13 — 13  of FIG.  9 . These three figures perhaps best show the relative thickness of the chamois&#39; various pad areas  59 ,  60 ,  61 ,  62 ,  63 , and  64 , and the heat-formed lines  66  that outline or boarder these pad areas. FIG. 14 is a view that is useful to identify exemplary and non-limiting physical dimensions of portions of female-use chamois  55 , these dimensions being typical of a chamois  55  in accordance with the invention for use by a female cyclist. 
     FIG. 16 is an exploded view of a portion of a female-use chamois  55  in accordance with the invention showing how chamois  55  is assembled from four pieces that include (piece  1 ) a garment-side cloth member  70 , (piece  2 ) a sheet  71  of relatively thin and low-hardness foam  71  having the same outer shape as garment-side cloth member  70  and having one through-hole  72  that is cut therein that complements the outer shape of (piece  3 ) a piece  73  of thick and high-hardness foam, wherein piece  73  of thick foam closely fits within the through-hole  72  that is formed in the sheet  71  of thin foam, and (piece  4 ) a body-side cloth member  74 . 
     As a feature of the invention, body-side cloth member  74  is formed of a synthetic leather and/or garment-side cloth member  70  is formed of a polyester, preferably a warp knit polyester tricot having a wicking finish, thin foam layer  71  is about 6 mm thick and has a hardness of about 20 d, and thick foam piece  73  is about 12 mm thick and has a hardness of from about 40 d to about 90 d. 
     FIG. 18 shows an embodiment of the invention wherein a female-use chamois  75  is a five-piece chamois having a body-facing cloth member  74  that is formed of a wicking polyester that includes a through-hole  77  that is formed therein so as to directly overly a thorough-hole  72  that is formed in thin and low-hardness foam layer  71 . The through-hole  77  within body-facing cloth member  74  is then filled by a piece  78  of similarly shaped and similar thickness synthetic leather that directly overlies a piece  73  of thick and high-hardness foam. Again chamois  75  of FIG. 18 is held together by an adhesive and/or by heat sealing. 
     FIG. 20 shows an embodiment of the invention wherein a female-use chamois  91  comprises a five-piece synthetic chamois having a continuous garment-facing cloth member  70 , a continuous thin and low-hardness foam layer  71 , a continuous body-facing cloth member  74  that includes one elongated and heart-shaped area  94  that receives a heart-shaped piece of thick and high-hardness foam  73 , and a heart-shaped piece of synthetic leather  78  that directly overlies thick foam piece  73 . 
     The top and bottom views of chamois  91  are generally identical to FIGS. 9 and 10. Chamois  91  includes weld lines  66  that are preferably formed as was above described relative to FIG. 21 wherein the heat/pressure process can also be used to form chamois  91  into a three-dimensional shape that approximates the pelvic girdle of a female cyclist. As a result, chamois  91  is devoid of stitching and the like. 
     An important feature of the FIG. 20 embodiment of the invention is that a first large size sheet can be formed that comprises the three layers  70 ,  71 ,  74 , and a second large size sheet can be formed that comprises the two layers  73  and  78 . Preferably, the first three-layer sheet and the second two-layer sheet are layer bonded so as to form unitary three-layer and two-layer sheet assemblies. 
     The first three-layer sheet assembly can be then stamped or cut to form a plurality of individual three-layer pieces that are each of the overall chamois-shape that is shown in FIG.  9 . In addition, the second two-layer sheet assembly can then be stamped or cut to form a plurality of heart-shaped pieces that are of the thick pad shape  59  that is shown in FIG.  9 . 
     A single chamois  91  can then be formed by using one of the three-layer chamois-shaped pieces and by using one of the two-layer heart-shaped pieces. 
     While physical dimensions of chamois in accordance with this invention are not to be construed as a limitation on the spirit and scope of the invention, FIG. 5 shows various dimensions of male-use chamois in accordance with the invention, these dimensions being shown in the following Table 1. In this male-use embodiment of the invention, the chamois had a major width L 10  of 205 mm and a major length L 15  of 355 mm.

     One manner in which the various cloth/foam/leather layers/pieces of chamois in accordance with the present invention can be formed into a single unitary chamois assembly is to provide these various members as synthetic members (i.e., as members that are formed by chemical synthesis), and to then fuse these synthetic members together by the application of heat and pressure, perhaps in the presence of a bonding agent such as an adhesive. When such a heat/pressure process is used to fuse the various chamois layers/pieces together, the resulting chamois is devoid of stitching and the like. 
     In addition, such a heat/pressure bonding process (perhaps with the additional use of a heat-setting adhesive) can be accomplished by a hot press that additionally operates to emboss the above-described thin lines that outline the various areas of the chamois. In addition, a heat-meltable plastic ribbon can be used intermediate the layers, and at the location of the thin lines that outline the various areas of the chamois as above described relative to FIG.  21 . 
     For example, a RF welding process may be used to fuse the various layers and pieces of the chamois together into a unitary chamois assembly, and a RF welding processes may also be used to form the chamois&#39; thin seam-like lines. 
     As a feature of the invention, a heat-forming process can then be used to form the unitary chamois assembly into a three-dimensional shape that generally conforms to the pelvic girdle of a male or a female cyclist. 
     The present invention has been described in detail while making reference to various embodiments thereof. However, since it is known that others skilled in the related art will, upon learning of this invention, readily visualize yet other embodiments that are within the spirit and scope of this invention, the above detailed description is not to be taken as a limitation on the spirit and scope of this invention.
