Retention device for a boot on a glide board with a dorsal support element

A retention device for retaining a boot on a snowboard, said retention device comprising:

• a base having a longitudinally extending lower surface adapted to receive a sole of the boot, said base including a heel support extending upwardly from said lower surface, said heel support including a raised portion;
• a dorsal support element against which an upper of the boot is adapted to be supported, said dorsal support element comprising a top part, a bottom part, and an intermediate part, said bottom part being connected to said base, said intermediate part being positioned between said top part and said bottom part, said top part and said bottom part being rigid, relative to said intermediate part, and said intermediate part being elastically deformable and comprising at least five generally upwardly elongated members, each said member comprising a rib, as viewed longitudinally, spaces being positioned between respective ones of said five ribs, said intermediate part allowing inclination of said top part with respect to said bottom part along at least one direction transverse of said device.
