Abstract
The present invention relates to a spring cartridge for a ski binding, wherein the ski binding has a rotatable front binding part for attachment of a ski boot, and is in particular a telemark ski binding. In the binding the spring cartridge provides tension to a biasing cable which biases the rotatable front binding part, so as to rotate the front binding part so that an attached ski boot would be brought into contact with the ski to which the ski binding is attached. The spring cartridge comprises an extended hollow housing open at both ends, a compression spring held within the extended hollow housing and a pressure stub held partly within the compression spring. The pressure stub is structured with an extended portion having a cross dimension smaller than the interior size of the compression spring and a head having a larger size than the interior size of the compression spring. The extended portion extends within the internal hollow of the compression spring and is also hollow and provided with an internal screw thread in the hollow section for threadable engagement with an external screw thread at the end of a biasing cable of a ski binding, the biasing cable being threadable through the center of the compression spring to the pressure stub. With rotation of the pressure stub this would thus lead to a change in the amount of the biasing cable held within the hollow section, when present, and thus change the amount of compressive force acting on the compression spring.
