Bindings
Bindings are separate components from the snowboard deck though they are a very important part of the total snowboard interface. The bindings main function are to hold the riders boot in place tightly so the rider can transfer their energy to the board.There are several types of bindings. Strap-in, step-in, and hybrid bindings are used by most recreational riders and all freestyle riders.
Snowboard bindings, unlike ski bindings, do not automatically release upon impact or after falling over. With skis, this mechanism is designed to protect from injuries (particularly to the knee) caused by skis torn in different directions. Automatic release is not required in snowboarding, as the rider's legs are fixed in a static position and twisting of the knee joint cannot occur to the same extent. Furthermore it reduces the dangerous prospect of a board hurtling downhill riderless, and the rider slipping downhill on his back with no means to maintain grip on a steep slope. Nevertheless, some ski areas require the use of a "leash" that connects the snowboard to the rider's leg or boot, in case the snowboard manages to get away from its rider. This is most likely to happen when the rider removes the board at the top or the bottom of a run (or while on a chairlift, which could be dangerous).
