ABSTRACT:
An improvement to known ski shock-absorption devices is constituted by an elongate beam having an arched portion of a length (LC) between a forward contact line and a rear contact line; the central portion including a binding mounting zone. The ski includes two transmitters located in the central portion and each on either side of the mounting zone. One of the ends of each transmitter is linked to the beam by a complete connection; the other end is connected by a partial connection, free in translation along a longitudinal direction, constituted of an elastic and/or visco-elastic element that resists the longitudinal displacement of the transmitter; the portion of length (l.sub.T1, l.sub.T2) of each transmitter between the two connections being left free, at least in translation, with respect to the beam; the ratio (l.sub.T1) of front transmitter over (l.sub.T2) of rear transmitter being comprised between 1.5 and 2.5 and (l.sub.T1 +l.sub.T2)/LC being comprised between 0.15 and 0.25.
