Abstract
A safety ski binding having a pair of sole holders pivotally secured to a base plate. Structure is provided for damping the movement of the sole holders to the ski boot releasing position. The damping mechanism includes a chamber having a fluid therein and a member movable in the chamber. The movable member in the chamber is connected through linkage to the sole holders and moves in response to a movement of the sole holders. The fluid on one side of the movable member will flow in a restricted manner to the other side thereof in response to sudden movements of the sole holders. The initial movement of the movable member is, therefore, restricted due to the fact that the fluid on the aforesaid one side of the movable member is restricted in its flow to the other side. Upon the movable member reaching a critical point in the chamber, fluid will then be permitted to pass through a bypass opening to facilitate an unrestricted flow of fluid around the movable member thereby permitting the sole holders to move in an unrestricted manner to the released condition thereof.
