A safety ski binding uses a rigid sole plate adapted to be releasably secured to a ski boot and having front and rear cam surfaces formed thereon for cooperation with toe and heel pieces that secure the sole plate, and thus the boot, to the ski. The toe piece and heel piece of the ski binding are both mounted on a ski plate or chassis secured to the ski in a predetermined position. The toe includes means defining a movable cam surface which engages the front cam surface of the sole plate, to releasably hold the plate on the ski, while the heel piece includes a resiliently biased cam that engages the rear cam surface of the sole plate when the sole plate is engaged in the toe piece and is flat against the ski, thereby to bias the sole plate towards the toe piece and normally maintain the front cam surface of the sole plate in engagement with the cam surface of the toe piece. The sole plate has a channel shaped configuration in section which is adapted to engage a pivot bar on the binding chassis to limit lateral movement of the sole plate to pivotal movement only while simultaneously permitting the sole plate to slide fore and aft on the ski.

A ski binding comprising a rigid sole plate including means for releasably securing the sole plate to the sole of a boot; said sole plate having front and rear cam surfaces thereon; a toe piece member adapted to be mounted on a ski in a predetermined position and including means defining a movable cam surface for engaging said front cam surface of the sole plate to releasably hold said plate on the ski; and a heel plate adapted to be mounted on said ski in a fixed position adjacent the rear cam surface of the sole plate when the sole plate is engaged with said toe piece and including resiliently biased cam means for engaging said rear cam surface of the sole plate and for biasing said sole plate towards said toe piece thereby to normally maintain said front cam surface of the sole plate in engagement with said toe piece; said means defining a movable cam surface in said toe piece comprising a cam member rotatably mounted in said toe piece and adapted to rotate upon lateral movement of the sole plate with respect to the toe piece, thereby to reduce resistance to binding release in the lateral direction; and means adapted to be mounted on the ski between the toe and heel pieces for cooperating with said sole plate to define a limited pivot point for the sole plate with respect to the ski during release of the binding, said means defining a limited pivot point also permitting simultaneous longitudinal movement of the sole plate with respect to the ski whereby the sole plate can be released from the ski in a twisting fall with simultaneous longitudinal movement of the plate with respect to the ski and pivotal movement of the plate about the limited pivot point; and said toe piece comprising an enclosed housing having an open end through which said cam member projects for engagement with said front cam surface, said housing, cam member and said sole plate having fixed predetermined dimensions with respect to the direction of ski length, and said housing having a plurality of indicia thereon representative of various boot sizes, said indicia being located in predetermined positions on the housing selected in accordance with the dimensions of the housing, cam member and sole plate whereby the appropriate indicia for a selected boot size can be aligned with the mid-chord point of a ski to locate said housing on the ski in the desired position wherein the ball of the foot in a boot of the selected size will be located at a predetermined distance from the point of engagement of the cam member and the front cam of the sole plate.
