Abstract
Abstract This invention relates to a ski boot provided with self-powered electric and/or electronic devices. The surface of the boot is covered by a plurality of solar cells, which convert the solar radiation into electric energy which acts to integrate a series of storage batteries contained in a box-type body rigidly attached, in a preferably removable manner, with the footwear structure. The series of storage batteries may be recharged by normal external source of electric energy, while the solar cells have the function of integrating the charge allowing a longer operation of the devices. The electric devices are of the resistive controlled type, for heating the footwear while those electronic consist of means for controlling the correct closure of the boot and/or means for control of the efforts to which the limb of the skier is subjected during use. Such control devices may conveniently cooperate with safety means provided in the ski to determine opening of the safety bindings in case of dangerous overloads.
