A shock-absorbing device for a gliding board. The gliding board includes two laterally spaced apart transmission rods; at least one fixed connection making it possible to rigidly connect the first ends of both rods to the gliding board; and at least one casing adapted to be connected rigidly to the board at a certain distance from the fixed connection, which has an opening for the introduction of an inserted portion of each rod, and at least one housing containing a viscoelastic material which is in contact with the longitudinal sliding surface along at least a certain length of the insertable portion of each rod in the housing, the material being biased in shearing during the displacement of each rod portion in the housing. An object of the invention is to provide a device that absorbs both the flexional and torsional forces of the portions of a gliding board that are the most exposed to these phenomena.

[ What is claimed is:] [13.] In combination, a ski and a shock-absorbing device, said shock-absorbing device comprising:two transmission rods laterally spaced apart, each of said transmission rods having a first end portion and a second end portion, said first end portions constituting fixed end portions and said second end portions constituting movable end portions;at least one fixed connection connecting said first end portions of said two rods rigidly to said ski;at least one casing connected rigidly to said ski at a certain distance longitudinally spaced from said fixed connection, said at least one casing having openings through which said second end portions are introduced, said at least one casing further having at least one recess for housing said second end portions of said two transmission rods, each of said recesses containing a viscoelastic material;each of said second portions of said transmission rods having a longitudinally extending sliding surface along a certain length and in contact with said viscoelastic material, said second portions of said transmission rods being arranged for rotational and translational movement in said at least one recess and being biased in shearing with said viscoelastic material during said movement.
