Abstract: Manual release means for safety ski binding. The sole holder for the forward or rearward end of a ski boot is pivoted to a housing and includes a pin within said housing which moves upwardly and downwardly with opening and closing movement of the sole holder. A pair of tonglike means resiliently embrace said pin for normally holding the sole holder in sole engaging position but are spread apart against an adjustable spring force upon imposition of a predetermined opening force onto the sole engaging means of the device. One side of said tonglike device is directly engaged by one end of the adjusting spring and the other side of said tonglike device is engaged by the reaction means holding the other end of said spring whereby to double the holding strength of the tonglike means for a given spring as compared to a construction in which the spring holds only one side of a pin retaining device.

Abstract: In a mounting device for the heel of a ski boot, a sole depressor is lockable in a heel-engaging pivoted position irrespective of the sole thickness or any snow packed beneath the sole. A locking arm carried by the sole depressor or a frame member passes through a hole in a clamping plate pivoted to the frame member or depressor, respectively. A spring acts on the clamping plate so that the locking arm is canted in the hole and binds on the edges of the hole, thereby locking the sole depressor against movement to a heel-releasing position. A handle can deliberately unlock the sole depressor by straightening the clamping plate against the action of the spring so that the locking arm is no longer canted and no longer binds on the edges of the hole.
