DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Referring now to FIG. 1, illustrated is a front elevation view of a lightweight brassiere, generally 100, according to a first embodiment. Brassiere 100 is characterized by a two-part cup construction 1, 2. A cut seam 7 connecting the two parts of the cup can be sewn and/or sealed by a sonic finishing technique. Seam 7 is at an angle to the horizontal plane as illustrated in FIG. 1, and traverses the two-part cup 1, 2 from generally the center of the brassiere A upward and outward across the cup. The seam 7 traverses the opposite cup in a mirror-image manner. Included in the embodiment of FIG. 1, the shoulder strap 8, is integral with the cup 9.

FIG. 2 illustrates a cross-sectional view through the two-part cup 1, 2, taken along line 2-2 of FIG. 1. The two part cup comprises an outer fabric layer 110, in two parts, upper fabric layer and lower fabric layer 101, 102, respectively. As an example only, either or both may be satin, though lace, cotton, synthetic fiber, or nearly any fabric may be substituted. Upper and lower fabric parts 101, 102 are joined at seam 103, in this case by a sonic finish, though alternately or additionally, they may be sewn. In a further embodiment, the outer fabric may comprise a single-piece seamless fabric panel. Optionally, the outer cover fabric may be bonded to the foam pad 112 (and any optional intervening layers), or simply overlie the foam pad 112 without bonding thereto, either before or after an optional molding step in the production of the brassiere.

The cup of brassiere 100 also comprises an inner foam pad 112, in upper and lower parts, 104, 105, respectively. The upper and lower parts 104, 105 are joined together at seam 106, also preferably by sonic finish. The seam 106 is preferably parallel with seam 103 and more preferably aligned with and adjacent to seam 103, though other embodiments of the present disclosure can differ. Seam 106 (and optionally 103) can begin at a lower and respective inward, with reference to a vertical centerline of the brassiere 100, quadrant of each cup 9, and traverse the cup 9 in a direction of the apex 10 of the cup 9, generally upward and outward. The apex is adjusted by sizing, but in general, for a size 34B, will be 3.25″ measured vertically from the bottom of the cup 1, with an incremental increase for each size step increase, for example 0.25″. This embodiment may be adjusted to any size, however, it is considered particularly well-suited to standard sizes 32-38B, and 32-36C.

Optionally, the foam pad 112 or at least the upper or lower part 104, 105, may include an inner and/or outer fabric laminate layer 107, 108, respectively. Inner and outer in this sense refers to the brassiere as it is intended to be worn by a user. The upper and lower parts 104, 105 of inner foam pad 112 have differing material characteristics. The lower part 105 is to provide adequate support to the wearer, while the upper part 104 is to be more flexible for comfort. To achieve this, the two sections are formed to have differing material properties. The lower portion 105 may be thicker, more dense, and/or have reduced elasticity, in order to provide the desired support. In a preferred embodiment, the lower portion 105 is substantially inelastic, i.e., dimensionally stable, within the plane defined by the molded shape of the inner foam pad 112 when subjected to the loads in its ordinary use which it is expected or designed to withstand. In one embodiment this feature is achieved by bonding an inelastic fabric to the lower part 105, e.g., as inner and/or outer fabric layer 107, 108. Suitable non-elastic fabrics include marisquette, which provide lightweight resistance to stretching, though taffeta, nylon, or other fabrics may be used, including those having woven or non-stretch knit construction. In comparison, upper part 104 may include an elastic knit fabric as either layer 107 or 108, or both, if both are present in the particular embodiment. An elastic fabric 107 and/or 108 laminated to a foam pad within upper part 104 would permit the elasticity of the foam to enhance user comfort.

The thickness of the lower part 105 may be adjusted as desired to provide more or less lift to the wearer's anatomy, thereby inducing an optional enhancement of the wearer's cleavage. By contrast, the upper part 104 will be comparatively thinner, less dense, and/or more elastic than the lower portion 105. In one embodiment upper part 104 exhibits an elongation of 50%, i.e., a 1-inch section stretches to 1.5 inches under a predefined test load (for example, ASTM D3574, or Polyurethane Foam Association). The foam pad 112 may be constructed of a polyurethane foam, or any cellular foam for which the characteristics of weight, density, thickness and elasticity can be controlled. Polyurethane foam of 38 kg per cubic meter (kcm) density is suitable in certain embodiments, though specific material and/or density may be altered within the scope of the present disclosure.

In addition to the two-part cup construction described above, the brassiere 100, and particularly the two-cup 1,2 thereof, may be molded after or during construction generally to the shape of the user's body for enhanced comfort.

Particular attention is given to the structure of the brassiere cup of the foregoing embodiment. The balance of features of the brassiere according to the first embodiment may be entirely conventional. Alternately, some or several or all of the features described with respect to the following embodiments may be incorporated into the foregoing embodiment, in addition to those specifically described.

Turning now to FIG. 3a, illustrated is a rear elevation view, i.e., as viewed from an inside with respect to the wearer, of another embodiment of a brassiere, generally 300, according to the present disclosure. The brassiere 300 includes a multi-part cup construction. Cup 301 includes a first lower cup part 303, including a substantially foam pad (not shown). The foam pad part of first lower cup part 303 is comparable to that of lower part 105 described with reference to the prior embodiment. An upper cup part 305 joins to lower cup part 303 along seam 306, preferably by sonic joining. A foam pad underlies upper cup part 305 in a manner similar to the upper part 104 described with reference to the prior embodiment. The cup 301 also includes a laterally outer part 307. Outer part 307 and a respective foam pad (not shown) generally correspond in material properties to lower cup part 303.

Shoulder straps 309 are integrally joined 311 to the cup 301 at outer cup part 307, and feature a wider thickness 311 corresponding to the wearer's shoulders, to distribute the pressure and increase comfort. Straps 309 may also be joined by stitching or ultrasonic welding for convenience of manufacture of to suit a particular design. Chest band 315 in the exemplary embodiment includes a double-layer satin outer portion and a mesh inside layer, again providing enhanced wearer comfort. Chest band 315 is clean-finished at its top and bottom edges with an enclosed elastic band 317. The chest band 315 is finished in a so-called ballet style 323. The neckline and armholes at strap 309 are also finished with an inward bonding for added comfort. Respective cups 301 are joined to one another by bridge portion 319.

Cups 301 are provided with an underwire 321, enclosed in a conventional fabric channel 322, which is optionally finished with two-needle stitching. In certain embodiments, the underwire 321 comprises a lightweight alloy metal, for example a Ti-alloy, offering superior stiffness for a given weight, i.e., enabling lightweight construction. Strap rings 325 that connect the shoulder straps 309 to the chest band 315 may also be of Ti-alloy, as may be strap length adjustment slides 326.

Turning to a front view of brassiere 300 as shown in FIG. 3b, the cup portion 301 includes an outer cover fabric in three parts, 327, 328, and 329. These generally correspond in size and position to respective underlying cup parts 303, 305, and 307. Fabric cover parts 327, 328 and 329 are preferably joined to one another by sonic sealing along seams 331, 332, but may be sewn or joined by other means.

In yet another embodiment, illustrated in a front elevation view as FIG. 3c, brassiere 300a includes a unitary outer fabric layer 340 overlying cups 301, i.e., without seams 331, 332 of the embodiment shown in FIG. 3b. The embodiment 300a is otherwise similar to the prior embodiment 300. It is further contemplated that, notwithstanding the three-part cup construction described with reference to FIG. 3b, an outer fabric layer overlying the cups 301 may be embodied as a two-part construction, in a similar fashion as described with respect to FIG. 1.

In still another embodiment, illustrated in rear elevation view as FIG. 3d, brassiere 300a includes cups 301b, having a multi-part construction. In this embodiment, an upper part 305 traverses the cup from an inward portion upward and outward to a top extent of the cup 301b. An outer portion 307b extends inward from a lateral extent, and a lower portion 303b extends upward from a lower extent. The respective upper, lower and outer portions are otherwise similar to their corresponding section described with respect to brassiere 300 in FIG. 3b, above.

Although the present disclosure has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. It is preferred, therefore, that the present disclosure be limited not by the specific disclosure herein, but only by the appended claims.
