  • Automatic damping/stiffening system
    Patent number: 5779257
    Abstract: A system for damping and/or stiffening a ski having a damping member and a stiffening member which are engageable and disengageable through the operation of a switch member. The switch member is engaged by a change in a threshold condition, such as a shift in the skier's weight during skiing. Engagement of the switch member engages the damping member and/or stiffening member. The system maintains the damping member and/or stiffening member in a disengaged condition until the skier commences a turn, engages the damping member and/or the stiffening member during the turn, and disengages the damping member and/or the stiffening member once the turn is completed.
