DETAILED DESCRIPTION

Referring now to the example embodiments of the present disclosure illustrated in FIGS. 1 to 3 and specifically with reference to FIG. 1, number 1 indicates, as a whole, a snow groomer for the preparation of ski slopes.

The snow groomer 1 is engine-driven so as to move forward along a snow-covered path in a moving direction D, and comprises a support frame 4, a driver's cabin 5, which is fitted on the frame 4, a passenger cabin 3, and two track conveyors 6 (only one of them is shown in FIG. 1), which are fitted on opposite sides of the frame 4 in a direction that is transverse to the direction D and perpendicular to the plane of the sheet of FIG. 1.

Each conveyor 6 comprises a set of wheels 8, which are fitted on the frame 4 so as to rotate around respective rotation axes that are transverse to the direction D, and a track 10, which is wound in a ring shape around the front wheel 8 and the rear wheel 8, and has a lower branch, which is kept in contact with the ski slope by the intermediate wheels 8.

The snow groomer 1 is further provided with a shovel 11, which is connected to the front part of the frame 4 so as to move snow masses along the ski slope, and with a mill 12, which is connected to the rear part of the frame 4 so as to process a snow mantel of the snow-covered path.

The snow groomer 1 further comprises an internal combustion engine 14, which is connected to at least one of the front and rear wheels 8, to the shovel 11, to the mill 12 via a transmission unit (which is not shown in the accompanying figures).

The driver's cabin 5 comprises controls 13 to guide the movement of the snow groomer 1 and to control the operating units of the snow groomer 1, such as the shovel 11 and the mill 12. The driver's cabin 5 comprises a seat for a driver U of the snow groomer 1 and can comprise one or two passenger seats.

The passenger cabin 3 is distinct from the driver's cabin 5 and is configured to ensure relatively high comfort for the passengers. The passenger cabin 3 is provided with controls to guide the movement of the snow groomer 1. The passenger cabin 3 serves the purpose of transporting a plurality of passengers along a snow-covered path, in particular a number of passengers greater than two. In another embodiment, the number of passengers of the passenger cabin 3 is greater than six, such as ten or twelve. In other words, the passenger cabin 3 is separate from the driver's cabin 5. By so doing, the snow groomer 1 used for passenger transportation does not need to be re-designed, but it can use many parts in common with other snow groomers used for other functions. In other words, the same driver's cabin 5 can be used both for snow groomers 1 having a passenger cabin 3 like the one according to this present disclosure and for snow groomers 1 without the passenger cabin 3.

With reference to FIGS. 1 and 2, the passenger cabin 3 is fitted on the frame 4 via steel and rubber connectors (silent block) so as to dampen the vibrations of the frame 4 to the passenger cabin 3.

Furthermore, with reference to the accompanying figures, the passenger cabin 3 comprises a bearing structure 20 comprising a floor 21; a roof 22; and a tubular structure 23, which extends between the floor 21 and the roof 22 and supports the roof 22.

The bearing structure 20, in particular the tubular structure 23, defines a protection cell, which is resistant to external loads and is configured to ensure an optimal structural resistance in case of rollover. To this aim, the tubular structure 23 of the bearing structure 20 comprises a plurality of tubes 26, wherein each tube 26 has a profile, in its cross section view, having a bilobed shape (FIG. 2). In other words, each tube 26 has a profile that, in its cross section view, has two lobes 27, which are joined to one another close to the base. In more detail, the bilobed cross section is also called butterfly or 8-shaped cross section. With reference to FIG. 2, the tubes 26 comprise housing seats 30 in the area of the base of the lobes 27. In other words, the tubes 26 comprise recesses in the area of the base of the lobes 27, which define the housing seats 30.

The tubes 26 ensure a relatively greater resistance to loads and ensure the relative stiffness of the tubular structure 23 in case of rollover of the snow groomer 1.

In another embodiment of the present disclosure, the tubular structure 23 comprises tubes with a circular cross section and housing elements coupled to the tubes, which define housing seats for the panels of transparent material.
