  • the invention "Binding snowboard binding release system", patent US2009243259, PCT/ES2006/000545, W02007/039655, publ. consists of a special drive, depending on the position of the body and the receiving device. Allows the opening of the bindings that keep the boots locked regardless of the pressure or torque applied to the bindings, with the system being activated voluntarily or involuntarily. Placed in the handle of ski poles and actuated remotely. However, it is not safe, because if the fastener is fastened too loosely, it can be unexpectedly released when the user moves while riding. In addition, the electronic sensor may not be adjusted correctly or not work at all, especially in conditions of variable pressure and temperature, which often occurs when riding in the mountains.
