Abstract
A device which can be fitted on the chair of a chairlift cable transport system used in tourist resorts and which provides passengers with a protection against cold and adverse weather conditions. Properly shaped plate elements are so arranged that in a deployed position they form a continuous protecting shield extending from above the seat to downward and frontward of the seat and that when in an upward folded position they are superposed so that the device has a very reduced area subject to wind action on empty chairs thus permitting the keeping of all chairs permanently on the cable without jeopardizing the whole line during adverse weather conditions. Springs bias the safe-guard rail towards the folded position. The device adds little weight, is easy to operate by the passengers and does not affect the usual embarcation or disembarcation procedures.
