  • This particular configuration allows the first strap 30 to sit over the second strap 40 so that it can freely stretch to an amount allowed by the coupling mechanism 50 and its location along the lengthwise direction 250 of the strap system 100. In other words, an amount of stretch possible by the first strap 30 is not hampered or disturbed by frictional forces that would be added if the first strap 30 were to be sandwiched between the wearer 406 and, for instance, the second strap 40.

Abstract

Certains aspects de la présente invention concernent un système de sangle ayant une extension réglable qui est approprié pour des vêtements de haut du corps, des vêtements de bas du corps et des articles tels que des sacs et des articles chaussants. Le système de sangle comprend une paire de sangles qui sont accouplées l'une à l'autre dans une relation de partage de face par un mécanisme d'accouplement. L'une des sangles de la paire de sangles a des propriétés d'étirement supérieures à celles de l'autre sangle. Un étirement total du système de sangle est réglable par déplacement du mécanisme d'accouplement le long d'une longueur du système de sangle.
