Highback with an adjustable shape

A highback for use with a component that interfaces with a rider's leg and is supportable by a gliding board the highback comprising:

• a highback body including an upright back member having a contoured shape to support a rear portion of a rider's leg, the highback body having a contoured shape that is adjustable between a first fixed shape with a first contour and a second fixed shape with a second contour that is different from the first fixed shape, the highback body being constructed and arranged for engagement with the component;
• wherein the back member includes a lower portion with a heel cup and at least one section adjustably supported on the lower portion;
• wherein the at least one section is flexibly supported on the lower portion of the back member above the heel cup;
• and
• wherein the at least one section is flexible relative to the lower portion of the back member along a flex zone formed in part by at least one aperture extending through the back member.

• wherein the back member includes a lower portion with a heel cup and at least one section adjustably supported on the lower portion;
• wherein the highback includes an adjustment mechanism to maintain the at least one section in one of a first fixed position and a second fixed position relative to the lower portion to fix the contoured shape in one of the first fixed shape and the second fixed shape;
• and
• wherein the adjustment mechanism includes at least one rigid link coupled to the at least one section and the lower portion.

A highback for use with a snowboard component that interfaces with a rider's leg and is supportable by a snowboard, the highback comprising:

• a highback body constructed and arranged to be supported on a snowboard component, the highback including,
• an upright back member constructed and arranged to support a rear portion of a rider's leg, the back member having a contoured shape to support a rear portion of a rider's leg on the snowboard, the contoured shape of the back member being adjustable between a first fixed shape with a first contour and a second fixed shape with a second contour that is different from the first fixed shape, the back member including a lower portion with a heel cup configured to hold a heel portion of a snowboard boot and at least one section supported on the lower portion, the at least one section being flexible relative to the lower portion along a flex zone defined in part by at least one aperture extending through the back member to adjust the contoured shape of the back member;
• a link adjustably coupling the at least one section to the lower portion to selectively maintain the at least one section in one of a first position and a second position relative to the lower portion to fix the contoured shape in one of the first fixed shape and the second fixed shape;
• and
• a pair of lateral arms extending from opposing sides of the back member to pivotally mount the highback to the snowboard component.

A highback for use with a snowboard component that interfaces with a rider's leg and is supportable by a snowboard, the highback comprising:

• a highback body having a contoured shape to support a rear portion of a rider's leg on the snowboard, the highback body constructed and arranged to be mounted on a snowboard component;
• and
• means for adjusting the contoured shape of the highback between a first fixed shape with a first contour and a second fixed shape with a second contour that is different from the first fixed shape;
• and
• a forward lean adjuster mounted to the highback body, the forward lean adjuster constructed and arranged to engage a portion of a snowboard binding to set the highback at a preselected forward lean position relative to the snowboard.
