MHLLEAM LI. BUEKLEY ATTCIRNEYI Dec. 16, 1958 w. J. BUCKLEY BRASSIERE 2 Sheets-Sheet 2 Filed Aug. 4, 1955 INVENTOR. WILLIAM LI. BU EKLEY ATTLIRNEK United States Patent 2,864,372 BRASSIERE William J. Buckley, Shelton, Conn.,'assignor to The La Resista Corset Company, Bridgeport, Conn., a corporation of Connecticut Application August 4, 1955, Serial No. 526,443 8 Claims. (Cl. 128-481) The present invention relates to brassieres, and particularly to an improved pneumatic pad structure therefor.

It is an object of the invention to provide a pneumatic pad having a plurality of air-tight air cells, 50 arranged as to give to the pad a desired predetermined external shape, and an internal shape to comfortably fit the wearer, the cells havinga cross-sectional shape providing a pad of substantial thickness at its central portion, and tapered to a relatively thin or feathered marginal portion.

It is further proposed to provide a pneumatic pad having a plurality of cells in each of which a relatively small amount of air is contained, the surface area of the respective cells being so proportioned with respect to their thickness that the volume of air contained in each of them will be substantially the same. Thus, under conditions where the entrapped air is subjected to expansion, as at high altitudes, the improved arrangement minimizes the effect of such expansion, the expansion in the individual cells being of such a small order that even under the most severe conditions it will not materially affect the overall shape of the pad structure, or subject it to the possibility of rupture.

A further object is to provide a pneumatic pad structure in which the separation walls between the cells are arranged to provide a grid-like frame structure which, while being flexible, will provide substantial internal support to maintain the desired shape of the pad.

Other objects and advantages of the invention will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawings wherein a satisfactory embodiment of the invention is shown. However, it will be understood that the invention'is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the appended claims.

Fig. 12 is a front elevation showing the completed pneumatic pad formed. by the, assembly of the pa'rts'shown in Figs. 8 and 9; and I Fig. 13 is a vertical sectional view, on an'enlarged scale, taken along the line13-13 of Fig; 12; I i Referring to the drawings, the brassiere'comprises a pair' of bust-receiving pockets 10 joined together along a center seam 11 and secured 'along itheir lower edges12 to a diaphragm band 13 provided with horizontal elastic inserts 14-14, the side edges of the bust pockets and the end edges ofthe elastic inserts being connected seams 15-15 to the forward edges of the back strap sections 16-1 6, one of which is provided. at its free-end with hook fasteners 17, while the other is provided at its free end with a horizontal elastic band 18 provided at its end with a tab 19 having eye fasteners 20 for engage: ment by the hook fasteners 17. Shoulder straps 21-21 are connected between the upper edges of the bust pockets and the back strap sections. l p The bust pockets 10 each consist of a porous .outer fabric layer 22 of full fashioned form, and a porousinner fabric layer 23, also fullfashionedand substantially conforming to the outer layer at its peripheral edge and having substantially less rounded projection, so as to provide a pneumaticpadreceiving space between them in their assembled relation, this space converging at the margins where the edges of the layers are brought together; Along the inner side of'the seam 15, the edger-of; the inner. layer 23 is suitably finished by hemmingxonthe like, and is unattached with respect tothe' seam 15 to provide a slit openin'g24 to the'space between the layers for the purpose of inserting or removing the pneumatic pad, as will presently more fully appear. l The fabric of the outer layer 22 may be of 'a'n y suitable porous material, as for instance, marquis'ette," satin, cotf ton, nylon or the like, which material is relatively thin and flexible, but is substantially non-stretchable so that the predetermined form given to'the outer layer will bethe external form of the brassiere; While the full-fashioning of the

layers

22 and 23 may be carried out in any of the usual ways, the same is shown as formed of 'upperand lower sections seamed along a transverse outwardly curved line 25, the lower section being provided-substantially centrally with an upwardly and outwardly curved'dart seam 26'. The inner layer 23 maybe of similar material to the outer layer or it may beof a porous 'lining material especially suited for soft engagement with the skin. I

The pneumatic pads, indicated generally as 27, are en gaged within the pocket spaces between the

layers

22 and 23 of the two bust pockets 10-10, being inserted therein through the slit openings 24. The pads are formed of an air-impervious non-elastic very thin light weight flexible sheet material, a suitable material for this purpose being a thin plastic sheet or film, for instance, one of the vinyl plastics, such as produced by the Bakelite Company of New York, N Y. under the name Vinylite, this ma-' terial being a copolymer of vinyl chloride andvinyl acetate. This material is capable of having two layers seamed together by the application of heat to form an air-tight bond between them.

The pad is formed 'of two pieces of plastic sheet ma terial adhered together by heat produced seams, as will presently more fully appear. The outer sheet 28 is fullfashioned into cup shape so as to impart thereto a similar shape to that provided by the full-fashioning of the fabric:

layer 22 'of the brassiere pockets; 10, this full-fashioning being preferably carried out by suitably'molding the plastie. sheet material to give it the desired shape. The inner piece of sheet material 29 is molded to shape and consists generally of a cupped wall having substantially less curvature than the outer sheet '28, so that when fitted together the space between the two sheets isrelatively wide at the center portion and is tapered. or feathered to the marginal edge.

Upon the forward side of the sheet 29 there is provided a framework of forwardly projected wall portions 30 which are adapted, as will presently more fully appear, to be secured at their forward ends to the inner side of the sheet 28 to constitute partition walls of a plurality of air cells. The pattern of the framework preferably consists of a substantially central circular wall, a circular wall in concentric outwardly spaced relation thereto, and a series of radial walls extending from the center circular wall to the periphery of the sheet, the height of these walls tapering from the central circular wall to the periphery. Theseparating walls are preferably of U-shape in cross section, being formed upon a suitable mold having projecting ribs about which the U-shaped walls are formed.

p The mold upon which the sheet 29 is formed may consist of suitable metal and be employed directly as the means for heat-seaming the two layers together, or a separate seaming die 31 corresponding in shape to the mold may be employed, the ribs 32 thereof being engaged within the U-shaped wall 30 of the sheet 29, as seen in Fig. 5. The outer sheet 28 is thereupon placed over the sheet 29 and a heat-seaming die 33 of suitable form to oppose the ends of the walls 30 and the periphery of the two interengaged sheets is brought into relation with the sheet 28. Thereupon the two dies are pressed together and by means of high frequency or electronic current passed between the dies the two sheets which are pressed together, as seen in Fig. 6, are heat sealed together, the material being substantially homogeneously'bonded at the seams 34 in air tight relation.

.During the joining of the two sheets the air in the air space between them is preferably placed under pressure so that the entrapped air in the cells formed by the joiningof-the two sheets is under pressure to maintain the cells in inflated relation. As seen in Fig, 7 ventilating holes 35 maybeprovided alongthe seams 34. The pneumatic pad,when engaged in the pocket as seen in Fig. 4, provideslan inflated support between the fabric layers Z2andj'23 and because the air is confined within a plurality of ,relatively small cells anyexpansion that may occur is'of such a relatively small order that no appreciable pressure will be exerted uponthe wearer. Also, the tapering cross-sectional shape of the pad is such that the relatively small area cells at the central portion con.- tain substantially the same amount of air as the relatively large area cells-at the margin.

If desired; the pad maybe stitched or otherwise secured directly intoa'b'rassiere structure in place of the fabric pockets 1,0, and'for this purpose the marginal edge por? tion ofithe, outer-layer28 preferably projects slightly with respect to the marginal edge portion of the inner layer 29 toprovidela flexible rim portion 36 for'convenient attaching by stitching to adjacent parts of a brassiere. Also, it is pointed out in this connection that the material of theouter layer 28, as well as the inner layer 29 ifqdesi 'fi s, maybe of an air-impervious type having nylon or other'suitable fabric incorporated as a lamination or covering of a thermoplastic sheet.

In, Figs. 8-13 there is illustrated a modified form of the invention in which the outer member 37 consists of a moldedcup-shaped layer 38 having secured to its inner side by heat produced bond an inner layer 39 having a plurality of embossed spaced cell-forming projections 40 molded therein,-these adapted to be disposed between air cells carriedupon, the inner member 41, and which consists of'acupped layer 42,upon the forward side of which there is secured by a heat, produced bond a molded layer 43 having a plurality of spaced air cell producing projec- 4 tions 44 arranged to fit within the spaces between theme. jections 40 of the member 37.

The two pieces are interengaged, as seen in Fig. 13, and are secured at the marginal portion by a heat produced scam 45. The peripheralmargins of the cupped

sheets

38 and 42 preferably project slightly beyond the edges of the molded

sheets

39 and 43, respectively secured thereto, so that when the two pieces are bonded together a relatively thin peripheral rim portion 46 is provided. As in the case of the pneumatic pad shown in the first embodimerit, the air within the cells is under pressure to inflate the cells and the pads may either be inserted in pockets 10 of the brassiere, as seen in Fig. 1, or they may be directly secured in a brassiere structure in:place. of the pockets 10 by stitching adjacent parts of the brassiere to the marginal rim 46 of the pad. Also, the material of the layer 38, as well as the layer 42, maybe of an air-imper vious type having nylon or other'similar fabric incorpo: rated as a lamination or covering of a thermoplastic sheet.
