In a strap assembly for carrying a portable device, in order to protect a user against the action of an unexpected sudden external force, a cord (20) for installing the strap assembly to the portable device is passed through an installation hole (34) of a coupling (30) from the inside such that a knot of a strap is supported by the rim of the installation hole. Coupling holes (11) in both ends of the strap (10) hung from the body of the user are fitted over support posts (37a, 37b) formed on the inner bases (38) of first and second coupling members (31, 32). Tapered surfaces (39a, 39b) are formed on portions of the cylindrical side surfaces of support posts (37). When the first and second coupling members are closed together with their rims superposed, protrusions (35) of one member engage recesses (36) of another coupling member. If a tension load in excess of a given level is applied to the portable device, a reactive force from the strap acts upon the tapered surfaces (39), resulting in force components that release the engaged state of these protrusions (35) and recesses (36). This causes the first and second coupling members (31, 32) to spread open, thus separating the strap (10) therefrom.

L'invention concerne un ensemble bandoulière permettant de porter un dispositif portatif, de façon à protéger l'utilisateur de l'action d'une force extérieure soudaine et inattendue. L'ensemble bandoulière comporte une cordelette permettant de fixer ledit ensemble sur le dispositif portatif, qui s'introduit depuis l'intérieur dans l'orifice de fixation d'un mécanisme de couplage, de façon que le noeud de la bandoulière repose sur le bord dudit orifice. Aux deux extrémités de la bandoulière accrochée au corps de l'utilisateur, des orifices de couplage sont fixés sur des tenons supports formés dans la base intérieure du premier et du second élément de couplage. Des surfaces inclinées sont formées sur une partie des surfaces latérales cylindriques des tenons supports. Quand le premier et le second élément de couplage sont refermés l'un sur l'autre et que leurs bords sont superposés, des protrusions formées sur l'un desdits éléments s'introduisent dans des cavités formées sur l'autre élément. Si la charge de tension appliquée sur le dispositif portatif dépasse un certain niveau, une force de réaction provenant de la bandoulière agit sur les surfaces inclinées en générant des composantes qui désolidarisent lesdites protrusions et cavités, de façon à provoquer l'ouverture des deux éléments de couplage et donc leur séparation de la bandoulière.
