The rear support (4) is in two parts: a hoop (12) hinged to the base plate (3) and a cuff (13) fixed to the hoop. The cuff is has greater rigidity than the hoop. The hoop acts with the arch (10), to limit front-to-rear articulation of the rear support, relative to the base plate. An Independent claim is included for the snow board fitted with the corresponding boot retainer. Preferred features: An adjustable stop (20) limits articulation. The stop is carried on the hoop. Hoop and arch lie behind the cuff, when the stop is set to an extreme position.
