A safety ski binding releasably holding a boot on a ski. The binding includes a jaw adapted to hold the boot and to pivot laterally, and an elastic mechanism biasing the jaw against lateral pivoting. When vertical stress acts on the binding, friction is generated which further biases the jaw against lateral pivoting, thereby preventing lateral release of the boot when dangerous lateral stress acts on the boot. To counteract this friction, a compensation mechanism is provided which counteracts the increased biasing against lateral pivoting both in the event upward vertical stresses act on the boot and in the event downward vertical stresses act on the boot. In one embodiment the compensation mechanism includes a pair of toggles which reduce the bias of the elastic mechanism in response to the upward pivoting of the jaw so that a constant bias against lateral pivoting is maintained on the jaw when vertical stress acts on the binding. In this embodiment a sensor is provided for converting downward directed stress to upward directed stress acting on the jaw. In another embodiment, the jaw pivots around two lines of support converging above the ski, so that any upward stress on the jaw has a component in the direction of lateral pivoting so as to increase the lateral pivoting force to compensate for the friction. Also provided in this embodiment is a sensor for converting downward directed stress to upward directed stress acting on the jaw.
