A load bearing fabric assembly having a frame, a carrier and a load bearing fabric. The load bearing fabric is attached directly to the carrier. The frame defines view ports to enable visual inspection of the junction between the carrier and the load bearing fabric after the carrier and fabric have been mounted to the frame. A method of manufacturing the carrier for such a load bearing fabric assembly includes the steps of: (a) placing the fabric inside a mold with at least a portion of the fabric directly engaging the surface of the mold; (b) injecting a molten thermoplastic into the mold to form the carrier, the molten thermoplastic having a melt point greater than that of the fabric; and (c) permitting the molten thermoplastic to cure to form a carrier directly on the fabric. In one embodiment, the fabric is positioned so that the entry of molten thermoplastic urges the fabric against a surface of the mold cavity.

1. A load bearing fabric assembly comprising: a carrier having a top, a bottom and a side extending between said top and said bottom, said carrier further having an outer surface, and said carrier being manufactured from a first thermoplastic having a first melt temperature;a load bearing fabric being manufactured at least in part from a second thermoplastic having a second melt temperature, such that said first melt temperature is higher than said second melt temperature, wherein a portion of said load bearing fabric lies against said outer surface of said carrier, said load bearing fabric being further attached to said carrier at a junction located on said side of said carrier, said junction being further defined as a location at which said load bearing fabric integrally joins with said carrier, and wherein another portion of said load bearing fabric wraps around said bottom of said carrier; anda component having a channel configured for receiving said carrier and said fabric for supporting said carrier and said fabric, said channel having an open end, a bottom and a wall extending therebetween, such that said portion of said fabric lying against said outer surface of said carrier is hidden from view by said wall of said channel when said carrier and said fabric are received by said channel, and wherein said component defines a first view port extending through said wall of said channel, such that said first view port is positioned through said component and said wall of said channel at a location between an entry point of said open end of said channel where said channel receives said carrier and said fabric, and said bottom of said channel where said portion of said load bearing fabric wrapped around said bottom of said carrier rest, wherein a centerline of said first view port is aligned with said junction and is substantially perpendicular to said wall of said carrier, whereby said view port permits visual inspection of said junction through said view port when said carrier and said fabric are received by said component, said component being securable to a support structure other than by use of said view port. 2. The load bearing fabric assembly of claim 1 wherein said component defines a second view port for viewing said junction. 3. The load bearing fabric assembly of claim 2 wherein said first view port and said second view port are defined in said component in different planes. 4. The load bearing fabric assembly of claim 3 wherein said component is further defined as a frame, and said first view port and said second view port being defined as apertures in said frame. 5. The load bearing fabric assembly of claim 4 where said frame has an interior and said first view port is located on said interior. 6. The load bearing fabric assembly of claim 2 wherein said load bearing fabric is attached to said carrier along a line which forms said junction; and wherein said first and second view ports are aligned to permit viewing of at least portions of said junction. 7. The load bearing fabric assembly of claim 6 wherein said component is a frame that defines said channel, said carrier being fitted within said channel such that said junction extends into said channel, said view ports extending through said frame to said channel to permit viewing of said junction. 8. The load bearing fabric assembly of claim 6 wherein said component is further defined as a frame including an interior surface on said channel, said first view port and said second view port defined along said interior surface of said channel. 9. The load bearing fabric assembly of claim 1, said carrier formed from the first thermoplastic material in a mold while the first thermoplastic material is above the first melt point; said load bearing fabric attached to the first thermoplastic material while the first thermoplastic material is above the first melt point, wherein at least one portion of the load bearing fabric is positioned to engage a surface of the mold as said carrier is formed, whereby the portion of the load bearing fabric is cooled by the mold. 10. The load bearing fabric assembly of claim 9 wherein the temperature of the at least one portion of the load bearing fabric is below the second melt point as the load bearing fabric is in contact with the first thermoplastic material while the first thermoplastic material is at a temperature above the first melt point. 11. The load bearing fabric assembly of claim 9 wherein a terminus of the load bearing fabric is attached to the carrier. 12. The load bearing fabric assembly of claim 1, said load bearing fabric being encapsulated along said outer surface of said carrier at said junction. 13. The load bearing fabric assembly of claim 12 wherein said component is a frame, said carrier being interfitted with said frame. 14. The load bearing fabric assembly of claim 13 wherein said first view port is located at a first location, wherein said carrier has a second view port for viewing said junction at a second location different from said first location. 15. The load bearing fabric assembly of claim 14 wherein said first view port and said second view port are in different planes. 16. The load bearing fabric assembly of claim 14 wherein said frame defines said channel, said carrier being fitted within said channel. 17. The load bearing fabric assembly of claim 16 wherein said frame includes an interior surface, said first view port and said second view port defined in said interior surface.
