1,025,998. Ski bindings. P. UNGER. Feb. 7, 1963 [Feb. 7, 1962], No. 5078/63. Heading A6D. A safety device for fastening boots to skis, comprises a housing on the ski containing a displaceable member which is coupled to an abutment for locating the boot on the ski the displaceable member being capable of spring-controlled rotational and longitudinal movement in response to forces developed between the boot and the ski. As shown in Fig. 1a, the housing 1 comprises a bearing sleeve 5 for a bolt 2 which comprises the displaceable member, and which is secured at one end to a crank 6 pivotally supporting the abutment 7. The bolt is normally held in the position shown in Fig. 1a by spring-urged balls 9,15 engaging respectively the inclined surface 10 or the groove 14 of the bolt, but in the event of the skier's falling forwards or sideways the bolt moves longitudinally and/or rotationally to move the abutment 7 away from the boot. Alternatively, as shown in Fig. 5a, the displaceable member 28 may be hollow and mounted for longitudinal displacement in a housing 31, and for pivotal movement about the axis of the pin 30. The member 28 is normally held against displacement by a spring- controlled detent 22, but in the event of the skier's falling forwards or sideways the resultant movement of the member 28 lifts the detent which in turn lifts the member 23, brings the pivot 25 of the plunger 26 beyond its dead centre position, whereupon the spring 27 becomes operative to release the member 23 and retract the abutment 7.
