performed by the foot when putting the ski back on and therefore requires one even for an average person Skiers' considerable effort.

In addition, the thickness of an accumulation of snow or ice under the heel of the boot has a very disadvantageous effect in such bindings by changing the setting of the binding or making it impossible to close it, for example.

The application is based on the task of eliminating these disadvantages in a simple and effective manner and in a reliable manner working. to create easily tensionable binding of the type mentioned.

This object is inventively achieved in that the, is used to clamp "the, or of the elastic means of blocking and / or elastic · Systems force required in two stages exerted * irrespective of whether the release of the binding is arbitrarily or randomly _s wherein clamping a first always., BSim LSsen comprises the same binding executed _£ and a second stage, carried out at the re-application? the position of the mechanisms h & i of the disengaged bond remains the same whether the disengagement was intentional or unintentional.

zes of the skier, the second when putting the binding back on, while the first in the case of an arbitrary detachment Step of re-tensioning the binding when putting down the ski by hand and the second when putting it back on the foot is carried out, as well as the second stage of tensioning after an accidental loosening of the binding.

According to preferred embodiments of the invention, the Rear ski safety binding that can be tensioned in two stages a cheek holding down the boot heel, which on her the the opposite side of the paragraph holding a cam profile has a recess that has a ball or the like. picks up which is located in the housing of the binding or is carried by a swivel arm, which in turn is pivotably mounted in the housing; between the housing and the pivot arm, a spring is arranged, which has the tendency to keep the profile with the ball or the like. in touch too hold, this spring being that of the locking system of the safety binding.

The center of the ball or the like. in their position in the one mentioned The recess determines the first center of rotation of the jaw during its elastic pivoting or deflection, which is achieved under the action of a spring, which is located in an elongated hole in the cheek between the heel of the boot

009828/1186

holding down part and the opposite, with the Cam profile provided part of the same sits and between the jaw and a firmly connected to the housing Axis is located; this spring is that of the elastic System of security binding. At maximum compression the spring becomes a rigid stop and the axis firmly connected to the housing then forms the second Axis of rotation of the cheek, through which a more rapid pivoting of this cheek and therefore also a quicker release of the boot heel is made possible.

Of course, the elastic rear ski safety binding, which can be tensioned in two stages, can contain mechanisms, in which the locking by means of a between a fixed and a movable part or between two movable Parts arranged spring takes place, the elasticity in turn by the attachment of a spring between a fixed and a moving part or between two moving parts.

Preferred embodiments of the invention are detailed below with reference to the schematic drawing, for example described; show it:

Fig. 7 is an external view of a known elastic rear binding which is provided with a re-tensioning in two-stage enabling system is equipped.

Referring to Figs. 1 and 2, the abscissa represents time expressed in seconds, for example; this axis is double, with two 0 points to make the diagrams clearer. The forces of the springs are plotted on the ordinate, with point 0 denoting the origin of the axes. In the In the following description relating to FIGS. 1 and 2, the spring E is the spring of the elastic system and the spring V that of the security locking system.

According to Fig. 1, which illustrates a random release, corresponds the time 1 of the binding in the locking position, the springs E and V being relaxed at their values 13 and 11, respectively. During time 2, spring E compresses to move from value 13 to value 17, while spring V at Value 11 remains relaxed; only at the maximum compression of the spring E does the spring V begin to "collapse? - ·

009828/1186

and go from value 11 to value 12 during time 3 · When this value 12, which allows unlocking, is reached, spring V remains constantly compressed during time * , while spring E relaxes, to return from value 17 return to value 13. Time 5, the idle time of the open binding, leaves the spring E at the minimum compression value 13 and the spring V at the maximum compression value 12; in this position the first tensioning stage of the safety binding has been reached.

The binding is now applied from time 6 onwards and must be able to enable the second tensioning stage of the safety binding to be carried out.

During the creation of the binding at 6, the spring V remains compressed, but the spring E takes its maximum compression

a pressure value IVf to stay there during time 7, with the spring V still compressed to the value 12. (Incidentally, this time span 7 can even become zero.)

During the time 8, the spring E, which is compressed to the value 17, allows the spring V to relax up to the value 11 with the continued application movement of the safety binding, whereby the. Period of time 9 begins, in which the spring V is relaxed at the value 11 and the spring E loses tension in order to reach the Get value 13.

009828/1186

The following time 10 * is, with regard to the values of the spring forces, nothing other than the rest period mentioned above 1.

It should be noted that between phases 20 and 21 the diagrams are reversible; in fact, each pen must do the work return above their maximum value.

FIG. 2 illustrates the case of an arbitrary loosening of the binding and there in the rest position of the open safety binding the spring E relaxed to the value 13 and the spring V must be compressed to the value 12, it is sufficient to the To act by hand on spring V to bring it to the compression point of value 12, which allows unlocking without to influence the compression of the spring E. So during time 1 the binding is closed, springs E and V are relaxed to their respective values 13 and 11; then during time 15 the spring V is pressed together by hand to open it bring the value 12, the spring E remains relaxed; so the first tension level of the binding is reached and one arrives at 16 to the rest zone of the bond.

The times 5, 6, 7, 8, 9 and 10 correspond to the second tensioning stage of the binding, which has already been explained with regard to FIG. 1.

In the case of the binding shown in Fig. 3, the boot strap is

sentence 26 corresponding to the position according to time 1 of the figures

1 and 2 held on the ski by means of the mouth 27 of a jaw 2 5, this jaw, after pivoting about an axis 34 fixedly connected to the housing 35, by means of a stop

2 8 is locked, which under the action of a spring 29 penetrates into a corresponding recess 31 in the jaw. the Spring 29 presses on a lever 30 which ensures the transmission of the force of this spring to the stop 28 j a screw 32 allows different settings of the spring 29,

To loosen the binding at will, you press the lever with your hand or the tip of a ski pole 30, which then assumes the position 36 indicated by dashed lines and thereby compresses the spring 29 (zone or period of time 15 of Fig. 2). The stop 28 can now come out of the recess 31 so that the jaw 25 can rotate freely about the axis 34. Pivoted during this rotation the jaw 2 5 the sector 44 which forms a pawl and which is released from the cutout 4-6 of the jaw 25 in order to follow a pivoting movement under the action of the return spring 45 to support against the profile 47 of the jaw.

In the position of the binding shown in FIG. 4, which corresponds to time 2 of FIG.

direction of the arrow 39 to raise the heel 26 of the force transmitted. This leaves the jaw 25 about the first pivot axis 41 pivot that of the one inserted into the recess 31 and remaining there under the action of the spring 29 Stop 2 8 is formed. During this rotary movement, the seated in an elongated hole 43 of the jaw 25 and pressed between this jaw and the fixed axis 34 arranged spring 42 together and seeks the jaw 25 and thus also the To bring paragraph 26 back into the position described with reference to Fig. 3, when the force transmitted in the direction of arrow 39 becomes zero. During this elastic period occurs under the action of the spring 45 on the jaw 2 5 pressing sector 44 does not come out of the cutout 46.

According to FIG. 5, the binding is in a position which corresponds to time 3 of FIG. The direction of the The increased force transmitted by arrow 48 compresses the spring 42 to a maximum extent until the latter comes to a rigid stop e.g. with turns on top of one another; thereby forms the axis 34 firmly connected to the housing is now the second pivot axis of the jaw 25, around which it moves under the action

of the torque generated by the force acting in the direction of arrow 48 seeks to rotate. The jaw loosens in the process 25 by compressing the spring 29 from the stop 2 8 and the sector 44 emerges from the cutout 46 to under the action of the spring 45 with the profile 47 in contact

come. During the rotation of the jaw 25 about the axis 34 the spring remains in constant tension} which is maintained by the profile 50.

In the position according to FIG. 6, which corresponds to time 5 of FIG corresponds, the binding is open, the spring 29 is pretensioned and the spring 42 is relaxed. To get into the "applied" position To return according to FIG. 3, the binding must go through the transition position described with respect to FIG Time 6 of Figures 1 and 2 corresponds with spring 42 compressed and axis 3H to the axis of rotation of the jaw 25, the latter now pivoting in the direction of arrow 5t During this pivoting, the man exercises on the Housing 3 5 supporting sector 44 a pressure in the direction of arrow 55 on the profile 47, which a lifting.des Long holes 43 and therefore the compression of the spring 42 brings with it.

Figure 7 illustrates an elastic binding of known type in the open position.

In order to achieve this position, one must press a pawl 88 with the hand or the tip of a ski pole, which rotates about an axis 91 and thus releases the lock formed by the cut-outs 89 and 90; these clippings

009828/1 186

belong to the body of the jaw 94 and to the pawl, respectively 88. During this movement, the spring 87 is compressed and the jaw 9 4 pivots about the one with the body 85 firmly connected axis 96, causing the pivoting of the sector 93 which leaves the profile 92 of the jaw 94 and passes over to the profile 9 8 of this jaw, against which it is supported under the action of the spring 100.

At the moment the binding is being put on, when the heel of the boot presses down the step lever 99, the axis 9 becomes 6 raised by pivoting about sector 93 and pushes the spring 84 together, whereby a pivoting of the jaw 9t about the axis 9 6 takes place until the moment when the lock formed by the cutouts 89 and 90 closes and the sector 93 under the action of the spring 81 to the profile 9 2 can get.
