Abstract: An all-terrain vehicle has a folding rear seat. The rear seat has a seating surface disposed between a pair of tire houses, a backrest disposed in a vehicle lateral direction at the rear of a front end portion of the seating surface, and a partition wall coupled with the backrest to define a front wall of the cargo deck. A lower end portion of the backrest supported to be rotatable forward with respect to the all-terrain vehicle about lower rotation axes arranged in the vehicle lateral direction. A partition wall is supported to be rotatable forward with respect to the all-terrain vehicle about upper rotation axes located above the lower rotation axes. The upper rotation axes are rotatably supported by the backrest.

Abstract: A vehicle having front and rear wheels includes a front wheel steering mechanism for providing a steering angle to a front wheel. Also, a rear wheel steering mechanism provides a steering angle to a rear wheel. The rear wheel steering mechanism has a first and second operational position; wherein the second operational position of the rear wheel steering mechanism is dependent upon the front wheel steering mechanism achieving a first predetermined steering state, preferably the steering through a prescribed angle or greater.

Abstract: A ski for a snow vehicle includes a ski body, a ski mounting bracket, a keel, a wear bar, and a glide member. The ski body includes a generally horizontal surface that contacts the snow when the ski is in use. The ski mounting bracket is located on a top side of the ski body. The glide member depends from the ski and is mounted at a position lower than the lowest most part of the wear bar.

Abstract: An adjustable ski track width mechanism allows adjusting the ski track between a narrow ski track width and a wide ski track width. The adjustable ski track width mechanism includes a steering mechanism that provides correct steering geometry and corresponding steering characteristics regardless of the narrow ski track width or the wide ski track width. The adjustable ski track width mechanism can be adjusted by the operator or automatically depending on operator preference or terrain conditions.

Abstract: An adjustment structure for the cushion unit of a snowmobile suspension system. The adjustment arrangement includes a mounting for the cushioning unit that is defined by a bolt and a pair of mount brackets having guide apertures formed therein. The bolt and guide aperture surfaces are treated so as to avoid shifting of the mechanism under the weight of the snowmobile when the mounting bolt is loosened for adjustment purposes.
