Abstract (en)
[origin: EP0639392A1] The invention relates to a ski consisting of a long beam (1) with an arched part (2) of length (LC) between a front contact line (20) and a rear contact line (21); said central part comprising an area where the bindings (5) are attached. The ski comprises two load transmitters (6, 7) positioned centrally (2), one in front of and one behind said attachment area (5). One of the ends (60, 70) of each load transmitter is connected to the beam by a full joint (8); the other end (61, 71) is connected by a partial connection means which is free to move in a lengthwise direction and is formed by an elastic and/or viscous component (90, 91) that tends to resist the lengthwise movement of said load transmitter. When flexing forces occur, the ratio of the movement ( DELTA 1) of the partially connected end (61) of the front load transmitter (6) to the movement ( DELTA 2) of the partially connected end (71) of the rear load transmitter (7) is between 1.2:1 and 2.5:1; and the ratio of the stiffness (K1) of the elastic and/or viscous component (90) of the front load transmitter (6) to the stiffness (K2) of the elastic and/or viscous component (91) of the rear load transmitter (7) is between 1.2:5 and 5:1. The invention relates to an improvement to known ski damping devices. <IMAGE>
