In a front jaw 101 equipping safety bindings for skis 100, a continuously smooth pin 106 is anchored in the horizontal arm 105a of a compensating lever 105, on which pin a sole-lowering device 108 is slidably mounted. A spring, particularly a helical spring 107, generally arranged on the pin 106, tends to push the sole-lowering device 108 downwards.

The invention relates to a parasol having a structural principle which is radically different from the traditional principle and in which the fabric is itself a structural element. This parasol is composed of a circular cover (1) made from fabric, stretched over a metal ring and stiffened by a central disc made from hard material having a diameter equal to approximately one third of its own. This ...
