Ski boot with self-powered ski boot control devices

In a ski boot having a ski boot outer surface including means for connecting with a ski having ski safety bindings, a self-powered ski boot control device comprising:

• a plurality of photovoltaic cells evenly arranged on said ski boot outer surface,
• an electronic control circuit connected with said photovoltaic cells for mutually connecting said photovoltaic cells selectively in series and in parallel and generating a supply signal having a voltage value greater than a preset desired value.
• storage batteries connected to said electronic control circuit for receiving therefrom and being recharged by said supply signal,
• electric service elements including boot closure sensors and overload sensors fed by said storage batteries and located in preset areas of said boot for generating sensors signals indicating selectively boot opening and overload conditions, and
• electronic control means fed by said storage batteries and connected to said electric service elements for receiving therefrom said sensor signals and generating control signals supplied to auxiliary members in the ski safety bindings cooperated with said electronic control means for actuation of said ski safety bindings.

In a ski boot having an upper and a shell defining a ski boot outer surface including means for connection with a ski having ski safety bindings, a self-powered ski boot control device comprising:

• a plurality of photovoltaic cells evenly arranged on said ski boot outer surface,
• an electronic control circuit connected with said photovoltaic cells for mutually connecting said photovoltaic cells selectively in series and in parallel and generating a supply signal having a voltage value greater than a preset desired value,
• storage batteries connected to said electronic control circuit for receiving therefrom and being recharged by said supply signal,
• electric service elements including boot closure sensors and overload sensors fed by said storage batteries and located in preset areas of said boot, such as a high upper portion, for generating sensors signals indicating selectively boot opening and overload conditions, and
• electronic control means fed by said storage batteries and connected to said electric service elements for receiving therefrom said sensor signals and generating control signals supplied to the safety bindings of the ski for actuation thereof.
