A snowboard with retractable braking device includes a board member with a brake member reversibly pivotal through a hole in the board member. When retracted, the bottom surface of the brake member is flush with, or above, the bottom surface of the board member. A retractor, such as a torsional spring, may resiliently hold the brake member in a retracted position. Also provided is a snowboard with an automatically deployable retractable braking device which deploys when the rider falls off a pressure pad affixed to the board member. Also provided is a braking device for boards that glide on snow, and an automatically deployable braking device for boards that glide on snow.

1. A snowboard with an automatically deployable retractable braking device, comprising: a) a board member with an opening through a bottom surface and a top surface of the board member, the top surface comprising a riding section the board member;b) a first automatically deployable braking device attached to the board member adjacent to the opening, comprising: i) a first brake member reversibly pivotal through the opening in the board member; andii) a pivotal connection between the first brake member and the board member;c) a brake deployment mechanism,d) an operative connection between the brake deployment mechanism and the first brake member,e) a pressure pad mounted on the riding section of the board member, the pressure pad being translatable between a raised position and a lowered position; andf) an operative connection between the pressure pad and the brake deployment mechanism,g) a first slider slidably attached to the bottom surface of the pressure padh) a first linkage member having a first end pivotally connected to the board member and a second end pivotally connected to the first slider,i) a second slider slidably attached to the board member,j) a second linkage member having a first end pivotally connected to the first slider and a second end pivotally connected to the second slider,wherein the brake deployment mechanism holds the bottom surface of the first brake member below the bottom surface of the board member when the pressure pad is in the raised position;wherein the first brake member further comprises a cam, and wherein the brake deployment mechanism further comprises an actuator that engages with the cam when the pressure pad is in the lowered position; andwherein the actuator is engaged with the cam when the pressure pad is in the raised position, and wherein the actuator is disengaged from the cam when the pressure pad is in the lowered position. 2. The snowboard of claim 1, further comprising a first retractor that resiliently holds the bottom surface of the first brake member flush with the bottom surface of the board member when the pressure pad is in the lowered position. 3. The snowboard of claim 1, further comprising a first retractor that resiliently holds the bottom surface of the first brake member above the bottom surface of the board member when the pressure pad is in the lowered position. 4. The snowboard of claim 1, wherein the pressure pad comprises an electronic force transducer, and wherein the brake deployment mechanism is electronically activated by a signal generated by the force transducer. 5. The snowboard of claim 1, further comprising: k) a second activatable braking device, comprising: i) a second brake member reversibly pivotal through the board member, the second brake member mounted in front of the first brake member; andii) a pivotal connection between the second brake member and the board member,l) an operative connection between the brake deployment mechanism and the second brake member,m) an operative connection between the pressure pad and the brake deployment mechanism,wherein the brake deployment mechanism holds the bottom surface of the second brake member below the bottom surface of the board member when the pressure pad is in the raised position. 6. The snowboard of claim 5, wherein the rear end of the second brake member is pivotally connected to the board member. 7. The snowboard of claim 5, wherein the first brake member and the second brake member are both reversibly pivotal through the riding section of the board member. 8. The snowboard of claim 5, further comprising a second retractor that resiliently holds the bottom surface of the second brake member flush with the bottom surface of the board member when the pressure pad is in the lowered position. 9. The snowboard of claim 5, further comprising a second retractor that resiliently holds the bottom surface of the second brake member above the bottom surface of the board member when the pressure pad is in the lowered position.
