The heel feed means act depending on the position of the latter on the ski.

This object is achieved according to the invention in that the two Means of the device that on the rear section of the boot heel two approximately equal, inclined, lateral Exert forces, the resultant of which is a back-to-front directed, the boot constantly against the front holding part of the Binding pressing force is about in the longitudinal direction of the ski ver sliding and adjustable on one side and the other surface of the rear holding part of the safety binding or the like. Are attached. Advantageously, the flexibility the holding of the boot heel by means of the two centering organs can be achieved either as a result of the elasticity of the boot sole when the centering organs themselves are rigid, or by the inherent elasticity of these organs, if they are made of spring steel, for example, or with the help of an elastic attachment of these organs to the rear binding or the like., For example by means of springs, guami pads or the like.

Below are various preferred embodiments of the on the basis of the drawing, for example

Fig. 5 is a plan view of the centering and horizontal front * Pushing device according to FIG. 1, shown in a position in which it holds a boot with a decentered heel that is inclined with respect to the axis of the ski;

Fig. 6 is a perspective view of a centering and advancing member for the boot heel, the one according to a A further embodiment of the invention provided for an adjusting device approximately parallel to the ski axis Has shift.

Genäfi Fig. 1, the two lateral, oblique, on the Boot heel 2 acting forces generated by means of two Ame 100, · which have two outwardly curved end projections 101 which are supported against paragraph 2. The two Arne 100 are on the outer casing 10t of the rear holding part 105 of the safety binding attached. In accordance with a feature of the invention, the ames 100 are in their movement can be adjusted and locked approximately in the axial direction of the ski, so that they can be adapted to several types of boots. The adjustment is carried out with the aid of grooves 106 located on the inner surface of the Ame 100, which are inserted into the side surfaces grooves attached to the housing 104 of the rear support member 108 intervene; the setting in the desired setting is done by means of a screw 110, which is advantageously with a washer 111 is provided, passes through a suitable, longitudinal slot 112 of the arm 100 and is

screwed into housing 104 · Arms 100 are either rigid, the resilience of the holder of the heel 2 achieved by the elasticity of the boot sole or elastic, e.g. by being made of spring steel, whereby they automatically provide the flexible support

The device according to FIG. 2 differs from that of FIG. 1 only in that the two, the arms 100 of FIG analog arms 115 are elastically attached to the housing 1OH of the rear holding part 105, in each case by means of two flexible washers 116 of the "Belleville" type, the

are arranged symmetrically opposite each other, under the head of the screws 110 of Fig.l corresponding Support screws 118 and try to press arm 115 against housing 1OH. Since the two arms 115 have slots 119, their movement is approximately in the longitudinal direction of the ski adjustable in the same way as the arms 100 in Fig.l, iäfelich by means of grooves 106 or 108 of the arm 115 or the Housing 1OH. A relatively strong pressure of paragraph 2 against your one and / or the other arm 115 seeks this arm or to remove these arms 115 from the housing 1OH while the washers 116 are pressed together.

In FIG. 3 are those corresponding to the arms 100 of FIG Arms 120 elastic on the housing 10H of the rear holding part

105, namely by means of flexible strips 121, e.g. consisting of rubber and arranged between the arms 120 and the housing 101, and by means of screws 122 with round, slit head. The arms 120 do not have a locking member, but have longitudinal slots 121 which allow them to be adjusted allow approximately in the longitudinal direction of the ski. The support force of paragraph 2 seeks to remove the arms 120 from a pressure of a given size from the housing 101 by the rear Part of the elastic strip 121 is compressed and the arms 120 around one of the lower surface of the heads of the front Pivot support point formed by screws 122.

The device shown in Fig. 1 differs from that shown in Fig. 3 only by replacing the elastic strips 121 with, for example, sinusoidal springs 13o which play the same role as the strips 121 mentioned.

In addition, compared to FIG. 3 for the attachment of the Arms 120 hex head bolts 132 used.

According to a properly illustrated embodiment of the device of FIG. 1, the springs 130 are between the arms 120 and the heads of the screws 132 are provided.

Fig. 5 shows the centering and horizontal feed device of Fig. 1, the arms 100 in the holding position of a boot

are set whose paragraph 2 is decentered and inclined with respect to the longitudinal axis of the ski. The two arms 100 are therefore blocked on the housing 1OH so that they are in position with the shoulder 2 in a position displaced with respect to the ski axis Come into contact. From this Fig. 5 it is clear how easy it is to center and hold boot heels of all kinds can be achieved with the device according to the invention.

In Fig. 6, the determination of the arms 140 takes place, of which only one is shown and which correspond to arms 100, 115 and 120 of the previous figures, by engagement of FIG grooves IH2 provided on the two upper and lower longitudinal edges of the arm IHO into the grooves IHH of two suitable ones Parts 1H5, which are firmly connected to the housing 1OH of the rear holding part 105, the fastening screw 1H6 passes through a longitudinal slot IH7 of the arm IHO and screws into the housing 1OH at 1H8.

Of course, the arms 100, 115, 120 or IHO can also

be attached to any other part than the rear retaining part of the safety binding, e.g. to a suitable plate provided with two side wings.

The scope of the invention is not exceeded, regardless of how the setting and locking elements of the " Boot heel acting arms and the elastic fastening
