Emergency Braking Ski Glove with GNSS/SOS System

When losing control on snow or on a slope, a skier may need an additional solution to rapidly increase interaction with the surface and help reduce sliding speed. The project also addresses a second challenge: after a fall, accident, or immobilization in a mountain environment, quickly locating the user can be critical for rescue operations. The objective was therefore to design a compact wearable device combining mechanical braking assistance with an electronic emergency location and alert system.

The developed solution is a technical glove incorporating a set of short claws connected to an internal mechanical support. A first version of the mechanism was produced using 3D printing to validate dimensions, glove integration, and the overall operating principle. A second version was then manufactured in stainless steel, including a stainless-steel internal support to improve the mechanical strength of the device. The concept also integrates an electronic safety module using GNSS satellite positioning. In an emergency situation, an SOS function can associate an alert with the user's geographical position. The prototype was tested and successfully demonstrated the overall concept. Testing also identified several areas requiring further improvement, particularly regarding ergonomics, mechanical integration, and safety.
