Abstract

A snowmobile footrest adapted to be disposed on a side of a snowmobile tunnel includes a plurality of interconnected ribs. At least one first rib extending in a first direction includes an upper first rib surface and a lower first rib surface defining a first rib height therebetween. A pair of vertical first rib surfaces, extending generally in a vertical direction between the upper and lower first rib surfaces, define a first rib thickness therebetween. The first rib height is greater than the first rib thickness. At least one second rib is connected to the at least one first rib. Each second rib extends in a second direction, the second direction being at an angle with respect to the first direction. The at least one first rib and the at least one second rib define at least one space therebetween. Snowmobiles having the footrests are also disclosed.

First claim

What is claimed is:

1. A snowmobile comprising:
a frame including a longitudinally extending tunnel;
at least one ski operatively connected to the frame;
an endless drive track operatively connected to the frame;
a motor supported by the frame and operatively connected to the drive track for propelling the snowmobile;
a straddle seat disposed above the tunnel and adapted to accommodate a rider;
a left footrest connected to the tunnel and disposed on a left side thereof;
a right footrest connected to the tunnel and disposed on a right side thereof,
each of the left and right footrests comprising a plurality of interconnected ribs extending generally horizontally, the plurality of ribs comprising:
at least one first rib extending in a first direction, each of the at least one first rib comprising an upper first rib surface and a lower first rib surface defining a first rib height therebetween, each of the at least one first rib comprising a pair of vertical first rib surfaces extending generally in a vertical direction between the upper and lower first rib surfaces, the pair of vertical first rib surfaces defining a first rib thickness therebetween, the first rib height being greater than the first rib thickness; and
at least one second rib connected to the at least one first rib, each of the at least one second rib extending in a second direction, the second direction being at an angle with respect to the first direction; and
at least one hole, the at least one first rib and the at least one second rib defining the at least one hole therebetween.

2. The snowmobile of claim 1 , wherein for each portion of any one of the at least one first rib having any one of the at least one second rib connected thereto,
the lower first rib surface of that portion is disposed vertically lower than the one of the at least one second rib connected thereto.

3. The snowmobile of claim 2 , wherein for each portion of any one of the at least one first rib having any one of the at least one second rib connected thereto,
the lower first rib surface is disposed vertically lower than the one of the at least one second rib connected thereto by a distance greater than the first rib thickness.

4. The snowmobile of claim 3 , wherein a ratio of the distance to the first rib thickness is greater than 1.5 and less than 5.5.

5. The snowmobile of claim 4 , wherein:
the ratio is a first ratio;
each of the at least one hole has a hole width measured in a direction perpendicular to the first direction; and
a second ratio of the hole width measured in millimeters to the first ratio is greater than 5.0 and less than 15.0.

6. The snowmobile of claim 3 , wherein:
each of the at least one hole has a hole width measured in a direction perpendicular to the first direction; and
a ratio of the hole width to the distance is greater than 1.0 and less than 6.0.

7. The snowmobile of claim 1 , wherein the first direction is a longitudinal direction of the snowmobile.

8. The snowmobile of claim 7 , wherein at a connection between any one of the at least one second rib and any one of the at least one first rib, the lower first rib surface of the one of the at least one first rib is disposed vertically lower than the one of the at least one second rib.

9. The snowmobiles of claim 8 , wherein the lower first rib surface of the one of the at least one first rib is disposed vertically lower than the one of the at least one second rib by a distance greater than the first rib thickness.

10. The snowmobile of claim 7 , wherein the second direction is a lateral direction of the snowmobile.

11. The snowmobile of claim 1 , wherein each of the at least one second rib comprises:
an upper second rib surface and a lower second rib surface, the upper and lower second rib surfaces being spaced from each other in the vertical direction and defining a second rib height therebetween;
a front second rib surface and a rear second rib surface extending between the upper and lower second rib surfaces and defining a second rib thickness therebetween, the second rib thickness being greater than the second rib height.

12. The snowmobile of claim 11 , wherein the second rib thickness is greater than the first rib thickness.

13. The snowmobile of claim 1 , wherein a first distance between two consecutive ones of the at least one first rib is smaller than a second distance between two consecutive ones of the at least one second rib, the first distance being measured in a direction perpendicular to the first direction, the second distance being measured in a direction perpendicular to the second direction.

14. The snowmobile of claim 1 , wherein the at least one first rib is integrally formed with the at least one second rib.

15. The snowmobile of claim 14 , wherein the at least one first rib and the at least one second rib are formed at least in part by extrusion.

16. The snowmobile of claim 15 , wherein the first direction is defined by a direction of extrusion.

17. The snowmobile of claim 1 , wherein each of the left and right footrests further comprises a plurality of teeth, each tooth of the plurality of teeth projecting upwardly from at least one of:
at least one of the at least one first rib; and
at least one of the at least one second rib.

18. The snowmobile of claim 1 , wherein:
the tunnel comprises a left side surface and a right side surface, the plurality of interconnected ribs of the left footrest being disposed leftwardly of the left side surface, the plurality of interconnected ribs of the right footrest being disposed rightwardly of the right side surface; and
each of the left and right footrests further comprises:
a front tunnel extension extending generally horizontally and laterally outwardly from the tunnel and being integrally formed therewith, the plurality of interconnected ribs being disposed rearward of the front tunnel extension;
a mounting bracket connected to a laterally outer edge of the plurality of ribs and removably connected to the front tunnel extension;
an inner mounting flange formed along a laterally inner edge of the corresponding plurality of interconnected ribs and to the corresponding one of the left and right side surfaces of the tunnel; and
an outer mounting bracket connected to a laterally outer edge of the corresponding plurality of interconnected ribs and to a laterally outer edge of the corresponding front tunnel extension; and
a rear mounting bracket connected to the outer mounting bracket and to the corresponding one of the left and right side surfaces of the tunnel.

19. The snowmobile of claim 1 , wherein, when viewed from a top of the snowmobile, each of the left and right footrests tapers in a rearward direction.

20. A footrest adapted to be disposed on a side of a longitudinally extending tunnel of a snowmobile, the footrest comprising:
a plurality of interconnected ribs, the plurality of interconnected ribs comprising:
at least one first rib extending in a first direction, each of the at least one first rib comprising an upper first rib surface and a lower first rib surface defining a first rib height therebetween, each first rib comprising a pair of vertical first rib surfaces extending generally in a vertical direction between the upper and lower first rib surfaces, the pair of vertical first rib surfaces defining a first rib thickness therebetween, the first rib height being greater than the first rib thickness;
at least one second rib connected to the at least one first rib, each of the at least one
