Abstract: A rollout cantilever arm for a modular cantilever rack system comprising a fixed horizontal member comprising two oppositely-facing fixed parallel load bearing surfaces, a roller mechanism and one or more interconnecting elements; and a mobile horizontal member partially encased in the fixed horizontal member. The fixed horizontal member comprises a roller-end engaged between the two load bearing surfaces and a load bearing surface supported by the roller mechanism. The interconnecting elements of the fixed horizontal member are configured for interconnecting two supporting vertical members of the modular cantilever rack system. The load-bearing surfaces extend perpendicularly between the two vertical members and the roller mechanism being located at an end distant from the two vertical members.

Abstract: A drive pulley for a continuously variable transmission comprising a fixed sheave having a first sheave face, a movable sheave axially movable relative to the fixed sheave along an axis of rotation of the continuously variable transmission, the movable sheave having a second sheave face, the fixed sheave and the movable sheave rotating about the axis of rotation and a separation measured at a constant radial distance from the axis of rotation along an axial direction between the first sheave face and the second sheave face, the separation varying around the axis of rotation.

Abstract: A snowmobile having a frame, a seat, at least one ski, a front suspension assembly connected to the frame and the at least one ski, a rear suspension assembly connected to the frame and to an endless track and an engine operatively connected to the frame and the endless track. The frame includes a longitudinal tunnel, an engine cradle connected thereto and extending forwardly therefrom. A front suspension module connected to the engine cradle and extending forwardly therefrom, is connected to the front suspension assembly. A forward support, connected either to the front suspension module or the engine cradle, extends rearwardly and upwardly therefrom. A fuel tank connected to the tunnel extends forwardly and upwardly from the tunnel to the forward support so as to form a structural connection between the tunnel and the forward support for transmitting loads therebetween. Frames for the snowmobile are also disclosed.

Abstract: A snowmobile has a frame including a tunnel, a least one ski operatively connected to the frame, a seat disposed above the tunnel, a fuel tank disposed on the frame, and an engine connected to the frame forwardly of the fuel tank. The engine has at least one cylinder, at least one intake port, at least one exhaust port, and a laterally extending output shaft defining an output shaft axis. An endless track is disposed at least in part under the tunnel and is operatively connected to the engine. An air intake system is fluidly connected to the at least one intake port. An exhaust system is fluidly connected to the at least one exhaust port. The exhaust system includes a muffler disposed between the output shaft axis and the fuel tank in a longitudinal direction of the snowmobile.

Abstract: A snowmobile has a frame with an engine compartment and a tunnel, a front suspension, at least one ski, an engine, a bracket having a first portion joined to the engine and a second portion having an aperture defined therein, an output shaft, a countershaft passing through the aperture, a motion decoupler disposed around the countershaft and being supported by the second portion of the bracket, the countershaft being rotationally supported in the motion decoupler, a driving pulley disposed on the output shaft, a driven pulley disposed on the countershaft, a drive belt looped around the driving and driven pulleys, and an endless drive track. The driving pulley, the driven pulley and the drive belt together form a continuously variable transmission.

Abstract: A snowmobile comprises a chassis including a tunnel, an engine disposed on the chassis at a forward end thereof and a seat disposed above the tunnel behind the engine. The seat has an inclined rear end face extending upwardly and rearwardly with respect to the upper surface of the tunnel, a cavity being defined beneath the seat between the inclined rear end face and the upper surface of the tunnel. The cavity is adapted to receive at least a portion of a transportable object therein, such that the transportable object is locatable above the tunnel at least partially beneath the seat.

Abstract: A detachable passenger seat is selectively mountable onto a base frame of a snowmobile having a straddle-type rider seat. The passenger seat includes a cushioned seat portion supported by a seat frame. A forward portion of the passenger seat includes a bottom surface contoured to fit over and be supported by at least a portion of a rearward end of the rider seat when the passenger seat is attached to the snowmobile. Upwardly extending flexible grab handles are mounted to the lateral sides of the seat frame. Upper portions of the flexible grab handles extend higher than at least a portion of an upper surface of a cushioned seat portion of the passenger seat. The flexible grab handles are designed to be rigid enough to provide support to a passenger and flexible enough to allow a passenger to easily dismount the snowmobile.
