Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing wherein:
FIGURE 1 is a perspective view of an upholstered assembly provided with a reinforced extensible insulator embodying my invention and showing parts broken away and in section.
FIGURE 2 is a fragmentary top plan view of an insulator embodying my invention.
FIGURE 3 is an enlarged fragmentary top plan view of the insulator, and showing parts broken away and in section.
FIGURE 4 is a longitudinal sectional view taken substantially on the line 44 of FIGURE 3.
FIGURE 5 is a fragmentary elevational view of one of the strands.
FIGURE 6 is a cross sectional view taken substantially on the line 66 of FIGURE 5.
In the drawing, A is a substantially rectangular extensible insulator embodying my invention disposed between a padding B for an exterior trim material C and a supporting spring structure D of an upholstered assembly.
As shown, the insulator A has a substantially rectangular extensible sheet 10 of flexible material, and separate substantially parallel extensible reinforcing strands 11 of uniform length threaded lengthwise through said extensible rectangular sheet.
The flexible material of said rectangular sheet 10 and said reinforcing strands 11 have intermediate their ends longitudinally extending portions 12. and 13 respectively of undulating form, so that said rectangular sheet and said strands are extensible. Successive undulations 14 respectively of said strands are disposed alternately upon opposite surfaces of the rectangular sheet 10 and are disposed in vertically opposed relation to successive undulations 15 of the flexible material of the rectangular sheet 10. Opposite end portions 16 of said strands 11 are upon the upper surface of the rectangular sheet 10 and terminate short of and adjacent to opposite ends of the rectangular sheet.
Preferably opposite end portions 17 of the flexible material of the rectangular sheet 10 are substantially flat and are terminally provided with open return bent or in wardly folded portions 18, and opposite end portions 16 of the reinforcing strands have deformed portions, preferably in the form of open return bent or substantially C-shaped portions 19. The end portions 16 and the deformed portions 19 of the strands 11 are disposed between the flat end portions 17 and the return bent portions 18 of the flexible material of the rectangular sheet, so that the deformed portions 19 of the strands are covered by the open return bent portions 18 of the flexible material of the rectangular sheet and are capable of being interlocked with the flexible material of the rectangular sheet to resist endwise movement of the strands bodily relative to said rectangular sheet.
In the present instance, the flat end portions 17 of the flexible materialof the rectangular sheet, the open return bent portions 18 of said flexible material, the end portions 16 of the reinforcing strands 11, and the deformed portions 19 of said strands at each end of the rectangular sheet have a common binder 20. Preferably each binder 20 is folded freely around the ends of the rectangular sheet 10 and has substantially flat substantially parallel portions 21 and 22 respectively located below the substantially flat portions 17 and above the return bent portions 18 of the rectangular sheet 10.
Each binder 20 is formed of flexible sheet material, and the substantially flat substantially parallel portions 21 and 22 thereof are held against displacement by fasteners 23 extending through the substantially flat end portions 17 and the open return bent portions 18 of the flexible material of the rectangular sheet at points between the end portions 16 of the strands. Preferably each binder 20 is formed from a material that is different than the flexible material of the rectangular sheet 16 and comprises a separate strip extending transversely of the rectangular sheet.
The fasteners 23 at each end of the rectangular sheet 10 are spaced apart and are substantially in alignment. Such aligned spaced fasteners 23 extend transversely of the rectangular sheet 10 at points substantially midway between the respective folds 24 of the binders 20 and the free edges 25 and 26 respectively of the substantially flat substantially parallel portions 21 and 22 respectively of the binders 20.
Although the various elements of my insulator may be formed of any suitable material for the purposes set forth, the rectangular sheet 10 is preferably formed of burlap, the strands 11 are preferably formed of wire, the binders 20 at opposite ends of the rectangular sheet 10 are preferably formed of crepe paper, and the fasteners 23 are preferably formed of metal and comprise conventional type hog rings that may be conveniently stapled to the binders 20 and to the flexible material of the rectangular sheet 10.
Thus, from the foregoing, it will be apparent that the insulator A is used between the padding B and the supporting spring structure D of an upholstered assembly, such for example a seat or seat back of a motor vehicle, and that in use the opposed undulations 14 and respectively of the strands 11 and of the rectangular sheet 10 will flex toward one another and thereby will permit both of said elements, namely the rectangular sheet 10 and the strands 11, to be longitudinally extensible to compensate for localized loads imposed upon them by one or more seated persons. Such binders not only facilitate the handling and removal of the insulators A when arranged in a stack, but also serve effectively to protect the padding B of the upholstered assembly from the deformed end portions 19 of the strands, and thereby preclude objectionable abrasion or tearing of such padding B when the insulators are installed.
