Abstract: Exoskeleton for physical activity, specially snow skiing, for preventing knee, leg and hip injuries by preventing the excessive torsion of the knee and other movements that could be dangerous for the person wearing it. The exoskeleton diverts the potential dangerous forces to the strong parts of the body and resists the generated forces when it reaches dangerous anatomical positions. The exoskeleton includes at least one first support member configured to couple above the knee; at least one second support member configured to couple below the knee; both of them linked together by a linkage assembly that limits that the coupling to the body of the support members reach dangerous positions; and at least one angle limitation mechanism that limits the relative rotation between the first support member and the second support member.

Abstract: The automatic release control system for controlling the connection between two elements, refers to a system for efficiently controlling the connection between two elements, preferably between a user and an apparatus, such as a ski or snowboard, on which the user's leg or foot is retained. The mechanism ensures that whatever the direction, application point and strength of the resultant of the forces transmitted by the apparatus to the leg, the releasable retaining system will release under the action of a potentially injurious force and remain in retaining state if no injurious forces are involved.

Abstract: Exoskeleton for physical activity, specially snow skiing, for preventing knee, leg and hip injuries by preventing the excessive torsion of the knee and other movements that could be dangerous for the person wearing it, furthermore allowing control over the skis during the practice of said sport. The exoskeleton includes at least one first support member configured to couple above the knee; at least one second support member configured to couple below the knee; both of them linked together by a linkage assembly that limits that the coupling to the body of the support members reach dangerous positions; at least one clutch mechanism operatively coupled between two elements of the exoskeleton, allowing the clutching and unclutching of said two elements of the exoskeleton; and at least one sensor that detects movement or/and pressure, of a part of the body of the skier to transmit a signal to the clutch mechanism.
