• the space 10 between the two long stirrup legs 5 and 6 must be at least large enough for the skiers to have enough space to hold on to the long L-legs during the ascent without pinching their fingers.
• the bracket parts 21 and 22 are the Q uerachse 9 on the intermediate piece 11 pivotally, so that the long legs 5 and 6 of the bracket parts may form 21 and 22 at an angle different from 0 as shown in FIG. 2 is seen.
• One of the short stirrup legs 7 comes closer to the ground and is suitable in this position for a small skier, while the other short stirrup leg 8 is further away from the ground and is therefore suitable for a taller skier.
• the two L-shaped bracket parts 21 and 22 swing back into their basic position. The swinging back can be done with a smooth storage of the bracket halves 21 and 22 happen automatically on the shaft 9 or the swinging back can be supported by the action of a spring (not shown).
• bracket halves 21 and 22 must not be pivotable too far apart, otherwise the short leg 7 or 8 of the other, unused bracket half would grind on the floor. This is achieved by using a limiting means 19 which is assigned to the bending halves 21 and 22.

• the longitudinal spar 43 has the effect, for example, that the temple halves 31 and 32 are located at a practical distance from the winder 3, which means that the ski lift bends Is seized by the ski lift user, particularly in the case of self-service ski lifts is made much easier and safer.
• the distance between the tow rope 4 and the floor of the boarding station is considerable.

• the connection between the longitudinal spar 42 and the bow halves 31 and 32 is accomplished with the aid of an intermediate piece 41, which is adapted for this purpose.
• This intermediate piece has a block 44 made from a tough but nonetheless somewhat flexible material, this material advantageously being a plastic. That area of the block 44 to which the longitudinal spar 42 is connected is provided with a longitudinal bore 39, in which the corresponding end part of the longitudinal spar 42 is inserted and fastened.
• a transverse bore 50 is made, in which the axle or shaft 49 is mounted.
• This bore 50 comprises three sections 52, 54 and 55, of which the central section 52 lies in an intermediate wall 53 which is located between the recesses 45 and 46 in block 44.
• the remaining two bore sections 54 and 55 are designed as blind holes in the side walls 56 and 57 of the block 44 and the end parts of the shaft 49 are located in these holes 54 and 55.
• the bore 50 is arranged in such a way that the holes in this bore 50 mounted shaft 49 passes through the recesses 45 and 46.
• the end portions 47 and 48 of the longitudinal stirrup legs 35 and 36 each have a bore 40 through which the shaft 49 also passes.
• the basic distance between the bracket halves 31 and 32 is given by the width of the intermediate wall 53 in block 44.
• the cross section of the bow legs 35 and 36 is at least substantially square in the region of these end parts 47 and 48 thereof.
• the depressions 45 and 46 in the block 44 have a square or oval cross section.
• the width of this cross section is practically the same as the width of the free end 47 or 48 of the longitudinal leg 35 or 36.
• the height of the depressions 45 and 46 in the block 44 is markedly greater than the height of the free end 47 or 48 of the longitudinal leg 35 or 36. This has the consequence that there is play 51 between the upper or / and lower outer surface of the respective leg end 47 or 48 and the corresponding inner surface of the recess 45 or 46 and that the bracket halves 31 and 32 in the Recesses 45 and 46 of the block 44 around the shaft 49 within a certain range thus can pivot.
• the long legs 35 and 36 of the bracket 30 are double-curved.
• a first curved leg section 58 or 59 (FIG. 3) adjoins the end section 47 or 48 of the longitudinal leg 35 or 36 pivotably mounted in the intermediate piece 41.
• This curved section 58 or 59 is oriented such that it lies in a plane in which the short stirrup leg 37 or 38 is also located and that it extends outwards from the space 60 between the stirrup halves 31 and 32.
• a straight leg section 61 or 62 can adjoin the outer end of the arc 58 or 59.
• a second curvature section 63 or 64 follows.
• This second arc 63 or 64 is advantageously in the same plane as the first arc 58 or 59.
• the second arc 63 or 64 is followed by the second and also rectilinear end portion 65 or 66 of the longitudinal leg.
• the second end parts 65 and 66 of the longitudinal legs 35 and 36 are practically parallel to one another and they are parallel or at least practically parallel to the first mentioned end parts 47 and 48 of the long legs 35 and 36.
• At the free end of this second end part 65 and 66 of the Longitudinal leg 35 or 36 one of the transverse legs 37 or 38 is attached.
• leg halves 35 and 36 results in an enlarged space section 67 between those parts 65 and 66 of the temple halves 31 and 32, where the hand of the ski air user holding the respective temple half is normally located.
• the risk that the hand or fingers of the ski air user are pinched between the temple halves 31 and 32, for example when two weighty ski air users use the same temple 30 and when the longitudinal legs 35 and 36 of the temple halves 31 and 32 Bending towards inside 67 is thereby reduced to a minimum.
• the inner end part of the respective transverse leg 37 or 38 is provided with a plate 71 or 72.
• These plates 71 and 72 stand from the inside side of the respective bracket half 31 or 32, so that the plates 71 and 72 are located in the intermediate space 67 of the bracket 30.
• the plates 71 and 72 can be relatively thick, the thickness of which can be between 1 and 5 cm. If the bracket halves 31 and 32 are at the same height while the bracket 30 is in use and if two weighty people use this bracket 30, the facing end faces of the plates 71 and 72 can be due to the flexibility of the longitudinal legs 35 and 36 rest on each other.
• bracket 30 is subjected to intermittent and large loads and thus also an extraordinary lateral bending of the bracket halves 31 and 32. Since the end faces of the plates 71 and 72 lie one on top of the other, the gap 10 or 67 between the temple halves 31 and 32 cannot close, and jamming of the hands or fingers of the ski air user between the temple halves 31 and 32 is thus completely ruled out .
• bracket halves 31 and 32 of the bracket tend to reduce the angle between them. This can have a negative impact on the safety of ski operation. This risk can be reduced by the plates 71 and 72, which are advantageously given a certain shape. It has already been explained that the bracket halves 31 and 32 can pivot about the shaft 49. The upper and lower edges 73 and 74 of the plates 71 and 72 should now run so that they lie on a beam S which passes through the axis of the shaft 49.
• the longitudinal legs 35 and 36 will very likely first bend against one another, so that the plates 71 and 72 will widen, w? l they are at different heights, shift laterally into a position in which they lie one above the other.
• the angle between the longitudinal legs 35 and 36 will decrease, as explained above. However, this is only possible up to the moment when the lower edge 74 of the top plate 71 or 72 hits the top edge 73 of the bottom plate. Thereafter, the angle between the bracket halves 31 and 32 cannot be further reduced. After the bracket 30 is relieved, the angle between the bracket halves 31 and 32 can grow back to its original size.
