On the ski behind the plate 26 is a customary elastic lock, generally designated 29 "intended to hold the plate in place". This lock has a holder 30 which is screwed onto the ski and has an angled part that extends over the plate streokt and carries a ball 31 in a vertical bore, which is pressed by a spring 32, the force of which can be adjusted by means of a screw 33. In order to hold the plate 26 in the normal position shown with solid lines, the ball 31 engages in a corresponding recess 34 made in the plate 26. Other means of retention could also be provided, for example a metal sheet which is flexibly urged against the plate by means of an adjustable screw and a spring and holds it in place by friction.

If the Sohuh, its front end in more familiar Way is held by a stop, exposed to a torque exceeding a certain value in the event of a fall is, the plate 26 pivots about the axis 27 against the effect that the ball 31 elastically on the Recess 34 exerts. The stirrup is released and the boot detaches from the ski. *

The front sole plate can also be moved, that is to say can be pivoted about a vertical axis in a known manner , when an approximately large torque acts on the shoe.

In the third embodiment shown in FIGS. 11 and 12, the device to hold the heel in place has a base plate 35 which can be swiveled around an axis 36 transversely to the ski and slidably mounted on a holder 37 in the manner of a hinge. The holder 37 has a sloped Stirnansohlag, dor with a correspondingly shaped forehead 38 of the plate 35 is engaged ₉ - welohe forehead on the edge of an opening 39 of the plate 35 is angeordn-et. The holder 37 is attached to the ski by means of screws 37 and is elastically pressed against the holder 37 by a spring 40, the pressure of which can be adjusted by means of a screw 41.

When the sdxih with a a predetermined value Excessive force is pulled upwards »for example in a forward fall, the bracket θ sees the plate 35t against the action of the spring 40, upwards, so that the Plate 35 swiveled around its hinge and released by the holder 37, whereupon the bracket 8, and thus the Shoe that is completely detached from the ski. Instead of being mounted like a hinge, the base plate could, for example, also have one Holders held with whale-tailed hands, in such a way that it would detach itself from the holder if a force exceeding a certain value pulls it upwards.

In the fourth shown in Figures 13 and 14 Embodiment has the device for holding the Absatsee a Basieplatte 42, which by means of a general

The rear end of the plate 42 has a spherical indentation 44, which, for example, can be produced duroh impressions, and which has an elongated opening 45, duroh welohe one vertical pin 46 protrudes. The spherical indentation 44 rests on a correspondingly shaped base 47t in one piece is formed with a holder 46 attached to the ski. A nut 49 is on the threaded end of the pin 46 is screwed to elastisoh the indentation 44 to press against the base 47, for which purpose a washer 50 made of rubber is provided. A protective cover 51 is over the spherical indentation 44. Behind the plate 42 is a generally designated 52 conventional elastic locking arranged for lateral and vertical holding of the plate. This lock 52 includes a holder 48 firmly connected block 53, with a horizontal bore in which a ball 54 rests, which is supported by a spring 55 »its Pressure by means of which a screw 56 can be adjusted is pressed against a corresponding recess which is browned in the wall of the indentation 44. Has at its front end The Baeieplatte 42 has a projection 42 'for hooking the BU-gel8 8, as has been described above. To hold on The plate 42 from below is provided with an additional lock which comprises a latch 57 which engages in a correspondingly shaped lip 58 which is located under the plate 42 protrudes · The bolt 57 becomes' duroh an open one
