Figure 1 is a partial perspective view of a chair lift according to the present invention.
Figure 2 is a top view of the chair lift of Figure 1.
Figure 3 is a side view of the chair lift of Figure 1. Figures 4 and 5 are views, on an enlarged scale, of two alternative embodiments of a ski stick retainer belonging to the chair lift of Figure 1 .
Figure 6 is a sectional view along the line VI-VI of Figure 3. Figures 1 to 6 show a chair lift for a two overhead cable transportation installation.
As shown more particularly in Figures 1 and 2, the chair lift 2 comprises a support structure 3 having a support hoop 4 and a bracket 5 on which is fixed the support arch 4. The chair lift 2 may further comprise a clamp disengageable coupling (not shown in the figures) fixed to the bracket 5 and for coupling the chair lift 2 to a traction cable of the conveyor.
Chairlift 2 further comprises a seat 6 multipart seat 7 arranged adjacent to one another. Each seat portion 7 comprises a seat surface on which a passenger can sit. According to the embodiment shown in the figures, the seat 6 includes six parts seat 7. However, the seat 6 could comprise a different number of seat portions 7, for example two, three, four or five parts seat 7.
Chairlift 2 also includes a folder 8. According to the embodiment shown in the figures, the file 8 has a first cross folder 9 and a second cross back 11 substantially parallel and spaced from each other, the first through file 9 being disposed above the second rail back 11.
Each seat portion 7 comprises a rear edge adjacent to the file 8 7a and 7b a front edge opposite the rear edge 7a respectively. Advantageously, the front edge 7b of each seat part 7 has a through notch 12 for passage of the legs of a passenger sitting on the respective seat portion 7.

According to the embodiment shown in the figures, each pass of notch 12 is centered with respect to the respective seat part 7 and extends over the entire thickness of the respective seat portion 7.
Such a configuration of each passage 12 of notch makes it possible firstly to define, in the central portion of the seat part 7 respective seat depth smaller and therefore allow a child, who thighs more short but at shorter legs can bend its knees while leaning against the folder 8, and secondly to maintain, in the side portions of the seat part 7 respectively, a conventional seat depth for an adult whose thighs are longer and the legs are apart.
The chair lift 2 comprises a railing 13 having a safety bar 14. The railing 13 is pivotally mounted about a pivot axis between a lowered position (see Figure 1) in which the safety bar 14 extends in front of the passengers sitting on the chair lift 2, and a raised position. Advantageously, when the handrail 13 is in the lowered position, the maximum distance between each pass of notch 12 and the safety bar 14 is less than 25 cm.
The railing 13 further comprises a plurality of support bars 15 each associated with a respective seat portion 7, and each fixed to the safety bar 14. Each support bar 15 extends from the safety bar 14 and extends perpendicular to the safety bar 14. Each support bar 15 is configured to extend between the legs of a user seated on the seat portion 7 when the respective guardrail 13 is in the position lowered. More particularly, each support bar 15 is configured to extend downwardly and in front of a central portion of the seat portion 7 when the respective guardrail 13 is in the lowered position. According to the embodiment shown in the figures, each support bar 15 is curved in its longitudinal direction.
Each support bar 15 has a supporting portion 16 configured to abut against the seat 7 respective portion, and more particularly against the front edge 7b of the respective seat portion 7, when the handrail 13 is in the lowered position.
Each support bar 15 comprises a first footrest 17, also called rest skis, and a second footrest 18, also called rest skis offset with respect to one another and extending substantially parallel to the safety bar 14. the first and second footrest 17, 18 of each support rod 15 are disposed so that when the guard rail 13 is in the lowered position, the first footrest 17 of each bar support 15 is disposed at a higher elevation than the second footrest 18 respectively. According to the embodiment shown in the figures, the first and second footrest 17, 18 of each support bar 15 are also arranged so that when the guard rail 13 is in the lowered position, the first footrests legs 17 of each support rod 15 is horizontally offset from the second footrest 18 respectively. However, the first and second footrest 17, 18 of each support bar 15 could extend vertically one above the other when the handrail 13 is in the lowered position.
Advantageously, the first footrest 17 of each supporting bar 15 has a lateral dimension less than the lateral dimension of the second footrest 18 respectively. Advantageously, the first and second footrest 17, 18 of each support rod 15 are respectively centered relative to the respective support rod 15, and extend laterally respectively on either side of the support bar 15 respectively.
According to the embodiment shown in the figures, each first footrest 17 includes a first portion 17a and a second support bearing portion 17b extending on either side of the respective support bar 15 respectively, and each second footrest 18 includes a first bearing portion 18a and a second bearing portion 18b extending on either side of the respective support bar 15 respectively. Advantageously, the first and second bearing portions 17a, 17b of each first footrest 17 are shorter than the first and second bearing portions 18a, 18b of each second footrest 18.
A configuration of the first and second footrest 17, 18 serves firstly to ensure optimal comfort for small passengers as they can rest their feet or their skis on the first footrest 17, and Moreover reduce the risk of conflict between the first footrest 17 and the large passenger shoes when they rest their feet or their skis on the second footrest 18.
Chairlift 2 further comprises several ski stick retainers 19 fixed on the seat 6 of the chair lift 2, and each disposed between two adjacent parts of seat 7, more particularly between the front edges 7b of two parts of seat 7 adjacent. The presence of such ski pole retainers 19 enables passengers to be able to releasably secure their ski poles on the seat 6, and therefore not worrying ski poles during the path on the chairlift 2. These provisions thus help to further improve the comfort of passengers, especially those with children.
As shown more particularly in Figure 4, each ski pole retainer 19 includes a retaining portion 21 made of elastically deformable material, for example elastomer. The retaining part 21 is provided with a notch 22 open retaining upwardly and configured to receive at least partially and retaining two ski poles 25. Thus, each retainer groove 22 has a depth greater than or equal to twice the diameter of a ski pole 25.
Each retaining notch 22 includes two side walls 22a and a bottom wall 22b. According to the embodiment shown in the figures, the two side walls 22a of each retaining notch 22 are inclined with respect to one another such that each retaining slot 22 has a cross section in plan of section perpendicular to the extending direction of the notch 22 of respective retaining substantially V and a width which decreases towards the respective bottom wall 22b.
Advantageously, each retaining notch 22 extends perpendicular to the safety bar 14, and has a minimum width smaller than the diameter of a ski pole 25.
As shown in Figures 4 to 6, each lateral wall 22a of each 22 retaining notch may be substantially smooth (see Figure 4), or comprise retaining elements, such as retaining pins (see Figures 5 and 6) configured to cooperate by friction with a ski pole 25 received in the respective retaining notch 22.
According to the embodiment shown in the figures, each ski pole retainer 19 includes two reinforcing elements 23, for example designed as reinforcing plates, arranged on either side of the respective holding part 21 and for fixing the respective ski stick 19 of restraint on the seat 6 of the chair lift 2, for example by means of fastening screws 24.
According to the embodiment shown in the figures, each ski pole retainer 19 is configured such that when a ski pole 25 is received in and retained by a ski pole retainer 19, said stick ski 25 is inclined relative to the vertical and is adapted to rest on back 8 of the chair lift 2, and for example on the first cross file 9 for a ski pole 25 large and on the second rail folder 11 for a ski pole 25 small.
