Abstract

A fuel tank and a seat assembly including the fuel tank is provided. The seat assembly includes a fuel tank, a seat frame securable to the fuel tank, and optionally a rear panel that supports a rearward portion of the seat frame. The seat assembly may define a chamber between the fuel tank and the rear panel. The seat frame is removably secured to one or both of the rear panel and the fuel tank. The fuel tank and rear panel may define a v-shape capable of distributing the rider load.

First claim

The invention claimed is:

1. A snow vehicle seat assembly, comprising:
a fuel tank that is positionable on a tunnel of a snow vehicle, the fuel tank including:
an upper surface defining a plurality of seat mounting features, wherein the plurality of seat mounting features are integrally formed with the upper surface of the fuel tank, and
a rearward portion defining at least a portion of a chamber;

a seat frame that is removably secured to the plurality of seat mounting features, the seat frame including a first portion positioned on the fuel tank and a second portion extending rearward therefrom; and
a rear panel that engages the rearward portion of the fuel tank to enclose the chamber therebetween and support the second portion of the seat frame.

2. The snow vehicle seat assembly according to claim 1 , wherein the chamber receives a battery therein and wherein the rear panel includes a fuel tank mount to secure the fuel tank to the rear panel.

3. The snow vehicle seat assembly according to claim 2 , wherein the second portion of the seat frame is removably secured to the rear panel, wherein the fuel tank includes two outboard legs extending rearward from a rear end of the fuel tank, wherein the rear panel defines two outboard chambers that receive the outboard legs therein, wherein a lower wall of at least one of the outboard chambers is positioned beneath the rearward portion of the fuel tank when the rear panel is secured to the fuel tank, and wherein the rear panel includes a first engagement member securable to an underside of the fuel tank, and a second engagement member positioned rearward of the first engagement member that is securable to the tunnel.

4. The snow vehicle seat assembly according to claim 2 , wherein a lower wall of the rear panel is positioned beneath the fuel tank and an upper wall of the rear panel is positioned on the upper surface of the fuel tank, wherein the battery is positioned on the lower wall of the rear panel.

5. The snow vehicle seat assembly according to claim 2 , wherein the fuel tank mount receives a threaded fastener to secure the fuel tank to the rear panel.

6. The snow vehicle seat assembly according to claim 1 , wherein the rear panel includes a rear wall extending from a base to the second portion of the seat frame, wherein a shelf extends from the base of the rear wall forward into the chamber, wherein the shelf supports a battery positioned in the chamber at least partially between the outboard legs of the fuel tank, and wherein the shelf maintains a gap between the battery and the tunnel when the seat assembly is positioned on the tunnel.

7. The snow vehicle seat assembly according to claim 6 , wherein the rearward portion of the fuel tank defines a first channel and an underside of the fuel tank defines a second channel that intersects the first channel, wherein the first channel routes battery cables from the battery to the second channel underneath the fuel tank.

8. The snow vehicle seat assembly according to claim 1 , wherein the rear panel includes a latching member that is selectively engageable with the seat frame to maintain the seat frame engagement with the plurality of seat mounting features.

9. The snow vehicle seat assembly according to claim 8 , wherein the rear panel defines a trapezoidal shape from which two wings extend and wrap around the rearward portion of the fuel tank.

10. The snow vehicle seat assembly according to claim 1 , wherein the plurality of seat mounting features include projections integrally molded with the fuel tank.

11. The snow vehicle seat assembly according to claim 1 , wherein the plurality of seat mounting features includes a pair of pockets defined in the upper surface of the fuel tank and a pillar projecting from the upper surface of the fuel tank capped by a disc having a larger diameter than the pillar.

12. The snow vehicle seat assembly according to claim 11 , wherein the seat frame includes a plurality of fuel tank mounting features which incorporates a pair of projections extending from a lower surface of the seat frame configured to be received within the pair of pockets and a keyhole-shaped opening in the lower surface of the seat frame configured to receive the pillar and the disc.

13. A snow vehicle seat assembly, comprising:
a fuel tank that is positionable on a tunnel of a snow vehicle, the fuel tank including:
an upper surface defining a plurality of seat mounting features, and
a rearward portion defining a rearward facing chamber, the rearward facing chamber positioned rearward from the plurality of seat mounting features;

a seat frame removably secured to the plurality of seat mounting features; and
a rear panel that engages the rearward portion of the fuel tank to enclose the rearward facing chamber therebetween,
wherein the rear panel and the fuel tank are configured to support a rider load.

14. The snow vehicle seat assembly according to claim 13 , wherein the seat frame includes a first portion defining a descending slope relative to the tunnel and a second portion defining an ascending slope relative to the tunnel.

15. The snow vehicle seat assembly according to claim 14 , wherein at least a portion of the rear panel is disposed underneath the first portion and the second portion of the seat frame.

16. The snow vehicle seat assembly according to claim 13 , wherein the rear panel is removably attached to the seat frame by a toolless latching member.

17. A snow vehicle seat assembly, comprising:
a fuel tank including a front portion, a rear portion, a base that extends from the front portion to the rear portion and is positionable on a track tunnel of a snow vehicle, and an upper surface that extends from the front portion to the rear portion, wherein the upper surface includes a protrusion extending therefrom, a first pocket, and a second pocket, wherein the first pocket and the second pocket are integrally defined by the upper surface, wherein the first pocket and the second pocket are positioned rearward of the protrusion, and wherein the protrusion, the first pocket, and the second pocket are positioned in a triangular configuration; and
a seat frame removably securable to the upper surface of the fuel tank, wherein the seat frame includes an opening, a first protrusion, and a second protrusion, wherein the first seat frame protrusion is receivable in the first pocket and the second seat frame protrusion is receivable in the second pocket when the fuel tank protrusion is received in the seat frame opening.

18. The snow vehicle of claim 17 , wherein the upper surface defines a first tier at least partially surrounding a second tier that extends upward from the first tier, wherein the fuel tank protrusion extends from a forward portion of the second tier and is positioned along a centerline of the fuel tank, and the first pocket and the second pocket are positioned along outboard sides a rearward portion of the second tier, and wherein the seat frame includes an outer flange that is positioned on the first tier of the upper surface of the fuel tank, and a concave portion surrounded by the outer flange that receives the second tier and is supported thereon when the first protrusion is positioned in the first pocket and the second protrusion is positioned in the second pocket with the fuel tank protrusion received in the seat frame opening.

19. The snow vehicle of claim 18 , wherein the fuel tank includes an outboard side defining a curved surface with an upper end extending along the upper surface of the fuel tank rearward from
