Automatic Release Device

Abstract

The task of the present invention is to provide an improved automatic release device for a binding of a touring ski; in particular, providing a lighter touring ski binding which is very sturdy and can be economically manufactured and which ensures safe release in the event of a fall. This task is solved by an automatic release device for a touring ski binding which comprises: a mounting plate, a pivot pin connected to the mounting plate and extending substantially vertical relative said mounting plate, a frame mounted to the pivot pin so as to be rotatable about a vertical axis, a clamping lever having at least one fixing jaw arranged on the frame to be rotatable about a horizontal axis, wherein the frame comprises: a base having a vertical opening for receiving the pivot pin, a horizontal opening for receiving a tensioning device which interacts with at least one first receiving area on the pivot pin such that the frame is fixed in an initial position and is rotatable about the vertical axis into a release position upon the overcoming of a defined force, a crosspiece having at least one second receiving area for the releasable fixing of the clamping lever in a fixed position, wherein the crosspiece is integrally connected to the base by means of at least two side components.
