to the upper side of the ski 1 an obtuse angle u03b2 the pressure spring 15 39 during swivelling of the braking mechanism from the retracted position to the braking position moves the swivel axle 13 39 of the guide plate 6 39 which swivel axle 13 39 is guided for sliding motion in the slide bearings 14 39 in a direction away from the ski fixed axis 5 39 and thus effects the swivelling of the braking mechanism into the braking position in this position of the ski brake the pressure spring 15 39 is preferably received in a correspondingly designed recess provided in the underside of the stepping plate 8 39 by suitably selecting the angle u03b1 or u03b2 and the dimensions of the guide plate 6 or 6 39 and the stepping plate 8 or 8 39 the braking angle which exists in the braking position of the ski brake can be selected freely within a relatively wide range the invention is not limited to the illustrated exemplary embodiments modifications including the rearrangement of parts are conceivable without leaving the scope of the invention thus it is possible to design the guide plate as a bar which is u shaped in a top view also it is possible to arrange several springs side by side furthermore it is possible to.
