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.
Claims29
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.
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.
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.
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
