Snowboard binding rotating plate
Swivel plates for snowboard bindings were developed to cancel the torsional forces which occur when a snowboarder has one foot out of the binding and one on the snowboard. The swivel plate enables the snowboarder to turn his foot in the running direction without taking the boot out of the binding. In this position, he can move forward like a skateboarder.
background
Softboot bindings are attached to the snowboard at a fixed angle, which in most cases places the foot almost perpendicular to the direction of travel. When a snowboarder reaches the end of the slope or a flat spot, one foot (usually the rear one) is usually removed from the binding and pushed forward with it. As the forefoot remains at the preset angle, the knee is twisted, which can lead to pain and injury.
Almost every tenth snowboard injury occurs while waiting in the lift queue or when getting on and off the lift. Snowboarders push forward with their free foot while the other foot (usually the forefoot) is still in the binding. The angle of 45 to 90 degrees that occurs exerts a strong torsional force on the leg and can lead to knee injuries (especially cruciate ligament tears) in the event of a fall.
technology
The rotating plate is attached between the snowboard and the binding or is already integrated in the binding. By manually releasing a safety mechanism, the lower plate (connected to the snowboard) and the upper plate (connected to the binding) can be rotated against each other. This means that the foot can be rotated freely in the binding and can be locked again at previously defined angles.
