Lightweight brassiere

Abstract

A lightweight brassiere is described that provides intended support to the user while increasing comfort by its structure and/or shape, and also by reduced weight. In particular a cup is made of a spacer fabric to provide the desired support at a minimum weight. Additional features include use of Ti-alloy materials in place of traditionally steel components, a narrower fabric channel for the underwire, and elimination of stitching by using sonic seal wherever possible.

1 . A lightweight brassiere comprising:
 a first concave cup;   a second concave cup laterally spaced from the first concave cup;   a central connecting portion connecting the first and second concave cups;   a first wing portion extending from the first concave cup;   a second wing portion extending from the second concave cup, wherein the first and second wing portions wrap around a chest of the user; and   a shoulder strap connected between at least one of the first and second concave cups and at least one of the first and second wing portions, respectively;   wherein each of the first concave cup and the second concave cup further comprise:
 a first fabric portion; 
 a second fabric portion positioned a predetermined distance in front of the first fabric portion; and 
 a plurality of resilient yarn fibers connecting the first fabric portion to the second fabric portion to provide support for a user's bust. 
   
   
   
       2 . The lightweight brassiere of  claim 1 , wherein each of the first concave cup and the second concave cup further comprise a finish layer positioned in front of the first fabric portion. 
   
   
       3 . The lightweight brassiere of  claim 2 , wherein the first fabric portion, the second fabric portion and the finish layer are made of breathable fabric. 
   
   
       4 . The lightweight brassiere of  claim 3 , wherein each of the first fabric portion, the second fabric portion and the finish layer are made of a biodegradable material that resists discoloration. 
   
   
       5 . The lightweight brassiere of  claim 4 , wherein the resilient yarn fibers are mono-filament fibers. 
   
   
       6 . The light brassiere of  claim 4 , wherein the resilient yarn fibers are multi-filament fibers. 
   
   
       7 . The lightweight brassiere of  claim 5 , wherein the first and second wing portions further comprise at least one fastening device operable to fasten the first wing portion to the second wing portion. 
   
   
       8 . The lightweight brassiere of  claim 7 , wherein the fastening device is a hook-and-eye type fastening device made of a titanium alloy. 
   
   
       9 . The lightweight brassier of  claim 8 , wherein each of the first concave cup and the second concave cup further comprise an underwire channel positioned in a lower portion thereof and operable to receive a metallic underwire, respectively. 
   
   
       10 . The lightweight brassier of  claim 9 , wherein the underwire channel has a width of 8 mm. 
   
   
       11 . The lightweight brassier of  claim 10 , wherein the shoulder strap is connected to at least one of the first and second wing portions via a metallic loop. 
   
   
       12 . The lightweight brassiere of  claim 11 , wherein the metallic loop is made of a titanium alloy. 
   
   
       13 . The lightweight brassiere of  claim 12 , wherein the shoulder strap further comprises a metallic slide operable to adjust a length of the shoulder strap. 
   
   
       14 . The lightweight brassiere of  claim 13 , wherein the metallic slide is made of a titanium alloy.
