ABSTRACT:
A vehicular snow ski steering keel bar is disclosed having a recessed surface portion extending at least partially along the length in the side surfaces of the bar. A lower side surface portion below the recessed surface portion includes lateral extensions extending beyond the recessed surface potion to collect and/or compact snow and/or material coming in contact with the steering keel bar. An upper side surface portion has lateral extensions that further direct snow into the recessed surface portion during turning and cornering of the bar. The cross-sectional shape of the bar includes a basic hourglass shape with curved and/or flat surfaces. Various cross-sectional shapes can be used along the length of the bar to fine-tune the turning characteristics of the steering keel bar. Different configurations or shapes can be utilized for the sides of the bar to vary the turning characteristics between left and right turns.
