Abstract

In a safety ski binding, a sole plate secured against lifting off is rotatably mounted on the ski surface in the heel region of the ski boot on a pivot extending perpendicular to the ski surface. The sole plate has a toe holder at its front end and a spring-loaded automatic heel mechanism for the ski boot at its rear end that opens to release the ski boot on the occurrence of a frontal fall load exceeding the spring resistance. To obtain complete release of the ski boot from the sole plate and thus from the ski on the occurrence of an excessive rotary fall load and for returning the sole plate to its normal position after the ski boot has been released, the sole plate has a slideway in the toe region as well as the heel region of the ski boot for securing the sole plate against lifting off and the automatic heel mechanism has a second degree of movement. Release of the ski boot is effected after the resistance of a separate spring has been overcome.
