摘要:
A highback for controlling a gliding board, such as a snowboard, through leg movement of a rider. The highback is provided with stiffness adjustability for accommodating the rider's particular riding preferences. Adjusting the highback stiffness allows the rider to selectively increase or decrease force transmission and board response based on individual riding preferences and/or riding conditions. Adjusting highback stiffness may also allow a rider to reduce pressure points between the highback and the leg, particularly the rider's calf muscle, for increased comfort while maintaining heelside support for board control. The highback includes a back member that may employ one or more sections that can be selectively adjusted to achieve a desired highback stiffness for board response and comfort. The degree of stiffness may be established by adjusting the flexibility of the highback at preselected locations of the back member. One or more interchangeable control elements may be mounted to the back member to adjust the highback stiffness.

A highback for controlling a gliding board, such as a snowboard, through leg movement of a rider. The highback is provided with shape adjustability for accommodating a rider's particular riding preferences. Shape adjustability may allow the rider to reduce pressure points between the highback and the leg, particularly the calf muscle, for increased comfort while maintaining proper heelside support for board control. Shape adjustability may also allow the rider to selectively increase or decrease force transmission and board response based on individual riding preferences and/or riding conditions. The highback may employ one or more sections that may be selectively arranged to achieve a desirable highback shape for board response and rider comfort. The highback may be rigidly fixed in the selected shape to maintain comfort while delivering desired power transmission to the board.
摘要:
A highback for controlling a gliding board, such as a snowboard, through leg movement of a rider. The highback is comprised of at least two distinct materials with different stiffnesses to achieve a desired blend of stiffness and flexibility. The highback may employ a material of greater stiffness in one or more regions to provide high force transmission between the rider and the board. The highback may employ a material of lesser stiffness in one or more regions where flexibility is desired for more gradual power transmission, comfort and/or to facilitate highback adjustability. The arrangement of the different materials provides a lightweight highback with a relatively sleek profile having selected regions of stiffness and/or flexibility.

One aspect of the invention is a removable strap for a snowboard boot to preventing the rider's foot from lifting in the boot. The ankle strap enables a soft boot to be used with both a strap-less step-in binding system, and a strap binding system. Another aspect is a snowboard binding including a strap adapted to releasably secure the snowboard boot and constructed and arranged to avoid creation of a pressure point at an instep bone of the rider. A further aspect is an apparatus comprising a snowboard boot and a strap attached thereto. The strap is arranged to prevent the rider's heel from lifting in the snowboard boot, and is constructed and arranged to avoid creation of a pressure point at an instep bone of the rider.
摘要:
An apparatus comprising a snowboard boot and a binding interface including an interface feature that is adapted to releasably engage with a snowboard binding. The binding interface is movably mounted to the boot so that the boot can flex in a side-to-side direction through an angle relative to the binding interface to provide side-to-side flexibility. In one embodiment, the binding interface is mounted to the boot at a pair of laterally spaced attachment points with a pair of strapless fasteners. In another embodiment, the binding interface is mounted to at least one attachment point and a portion of the boot is flexible between the attachment point and a side. In other embodiments, at least a portion of the interface feature does not protrude below the bottom surface of the boot, and the interface feature does not protrude beyond the sides of the boot. In yet other embodiments, the apparatus includes an adjustment member to adjustably restrict the side-to-side flexibility between the boot and the binding interface, and a dampening element that dampens the side-to-side flexibility. The boot may include an arcuate lower surface that extends across the boot with the binding interface mounted to the boot below the arcuate lower surface. A fluid-filled bladder may be provided to control the side-to-side flexibility of the boot. The binding interface may be slidably mounted to the boot using arcuate surfaces, such as convex and concave surfaces, that allow the boot to slide across the binding interface.

An exercise apparatus resistance unit includes flex members to bend to provide a resistance, a first end piece, a second end piece provided another end of the flex members to secure the flex members to rotate and translate within the body according to a bending motion of the flex members, a main pulley, and auxiliary pulleys rotatably provided on the first end piece. The resistance unit may provide a variable resistance.
摘要:
An alpine ski binding system for releasably securing a ski boot to a ski. The binding system includes a secondary toe release that provides an attenuated release threshold under lateral shear loading conditions that can cause anterior cruciate ligament injuries. The secondary toe release responds to a trigger that senses the lateral shear loads applied to the inside (medial) afterbody of the ski and triggers the secondary toe release the boot at an attenuated release torque. Lateral shear loads applied to the ski along the leading (medial) forebody and along the entire outside (lateral side) of the ski substantially do not cause the trigger to trip.
