Description

The present invention relates to a seat for a ski lift installation, such as a chairlift for an aerial cableway installation.

A chairlift of an overhead cable transport installation, comprises in a known manner: a backrest, and a seat comprising a plurality of seat parts on each of which a passenger can sit, and a railing comprising a railing bar. security and a plurality of support bars fixed to the security bar and extending transversely to the security bar, the railing being movably mounted between a raised position and a lowered position, the railing being configured such that, when the railing is in the lowered position, the safety bar extends at least partially in front of the passengers sitting on the seat portions and each support bar extends between the legs of a user sitting on the seat. respective seat part.

In order to improve the comfort of the passengers, each support bar advantageously comprises a footrest on which a passenger can rest his feet or his skis.

A major disadvantage of such a chairlift lies in the fact that a small passenger, such as a child whose legs are shorter than those of an adult, can not rest his feet or his skis on the rest footboard associated with its place while being backed to the back of the chairlift.

Therefore, a child tends to move closer to the front edge of the chairlift so that he can reach the footrest and rest his feet or skis, which is very dangerous since the child can then slide below the safety bar and drop off the chairlift if the guardrail is in the lowered position, or drop directly from the chairlift as long as the guardrail is still in the raised position.

The present invention aims to remedy these disadvantages.

The technical problem underlying the invention is therefore to provide a seat for a lift facility that is simple and economical structure, while ensuring a safe and comfortable transportation of passengers, including small passengers. For this purpose, the present invention relates to a seat, such as a chairlift, for a ski lift installation, such as an overhead cable transport installation, the seat comprising: a seat comprising at least one seat part on which a passenger can sit, - a guardrail comprising a safety bar and at least one support member fixed to the safety bar and extending transversely to the safety bar, the guard being movably mounted between a raised position and a lowered position, the safety bar being configured to extend at least partially in front of a passenger seated on the at least one seat portion when the guardrail is in the lowered position, and at least one support member being configured to extend between the legs of a passenger seated on the at least one seat portion when the guardrail is in the lowered position, characterized in that the at least one support member a support member includes a first footrest and a second footrest that are configured to be vertically offset relative to each other when the guardrail is in the lowered position.

Such a configuration of the first and second footrests provides optimum comfort for a small passenger, since the latter can easily rest his feet or skis on the highest footrest of the first and second seats. feet, while being leaning against the back of the seat. These provisions thus make it possible to increase the comfort of the passengers of small sizes, while ensuring them a great security.
