Abstract
A bra strap has stretch properties such that the strap exerts a force that is sufficient to provide adequate support but does not exceed that which is comfortable to the wearer over a wide range of elongation. Thus, the bra strap may be worn by women of varying heights without the need to change the length of the strap prior to use.
Claims
exact text as granted — not AI-modified1 . A strap having a flat power curve for incorporation into women's clothing including brassieres, sports bras, and swimwear,
wherein the strap stretches no more than 25% when subjected to a load of 0.6 lbf and stretches at least 60% when subjected to a load of 2.2 lbf when the strap is subjected to the Power Curve test method.
2 . The strap of claim 1 , wherein the strap is manufactured by weaving.
3 . The strap of claim 1 , wherein the strap comprises elastomeric yarn.
4 . The strap of claim 1 , wherein the strap comprises covered elastomeric yarn.
5 . The strap of claim 1 , wherein the strap has a width of between 10 and 14 millimeters.
6 . The strap of claim 1 , wherein the strap stretches between 10% and 25% when subjected to a load of 0.6 lbf.
7 . The strap of claim 1 , wherein the strap stretches between 25% and 50% when subjected to a load of 1.2 lbf.
8 . The strap of claim 1 , wherein the strap stretches between 35% and 85% when subjected to a load of 1.6 lbf.
9 . The strap of claim 1 , wherein the strap stretches between 60% and 110% when subjected to a load of 2.0 lbf.
10 . The strap of claim 1 , wherein the strap stretches between 70% and 125% when subjected to a load of 2.2 lbf.
11 . A bra comprising a strap according to claim 1 .
12 . A bra comprising a strap, wherein the difference between the Calculated Stretched Length of the strap when subjected to a load of 2.2 lbf is at least four inches greater than the Calculated Stretched Length of the strap when subjected to a load of 0.6 lbf,
wherein the loads are applied according to the Power Curve test method.
13 . The bra according to claim 12 , wherein the difference between the Calculated Stretched Length of the strap when subjected to a load of 2.2 lbf is at least five inches greater than the Calculated Stretched Length of the strap when subjected to a load of 0.6 lbf.
14 . The bra according to claim 13 , wherein the length of the strap in an unstretched state is less than 10 inches.
15 . The bra according to claim 12 , wherein the difference between the Calculated Stretched Length of the strap when subjected to a load of 2.2 lbf is at least six inches greater than the Calculated Stretched Length of the strap when subjected to a load of 0.6 lbf.
16 . The bra according to claim 15 , wherein the difference between the Calculated Stretched Length of the strap when subjected to a load of 2.2 lbf is less than eight inches greater than the Calculated Stretched Length of the strap when subjected to a load of 0.6 lbf.
17 . The bra according to claim 12 , wherein the difference between the Calculated Stretched Length of the strap when subjected to a load of 2.2 lbf is approximately 6½ inches greater than the length of the strap when subjected to a load of 0.6 lbf.
18 . The bra according to claim 17 , wherein the length of the strap in an unstretched state is less than 10 inches.
19 . A strap comprising a flat power curve,
wherein the difference between the percent of stretch of the strap when subjected to a load of 2.2 lbf and the percent of stretch of the strap when subjected to a load of 0.6 lbf is at least 50% when the strap is subjected to the Power Curve test method.
20 . The strap according to claim 19 , wherein the difference is at least 70%.
21 . The strap according to claim 20 , wherein the difference is at least 90%.
22 . A strap for incorporation into women's clothing including brassieres, sports bras, and swimwear,
wherein the strap stretches an elongation E, measured as a percentage, under force F, force F being applied by stretching the strap according to the Power Curve test method, wherein
