Bench seat for a chair of a chairlift

Abstract

A bench seat for a chair of a chairlift having a cross support bar ( 2 ) fastened to a supporting frame member ( 1, 9 ) of the chair. The front bench seat element ( 5 ) is supported by said cross support bar ( 2 ). The bench seat is furthermore provided with a backrest ( 10 ). The bench seat element is a one-piece bench seat top ( 5 ) that is hinged on its sides ( 6, 7, 8 ) to said supporting frame member ( 1, 9 ). Said backrest ( 10 ) is designed as a load-carrying laminated element, which is hinged on its sides ( 11, 12 ) to said supporting frame member ( 1, 9 ). Said backrest ( 10 ) is thereby provided with a transversely running supporting surface ( 13 ) at its lower region onto which the rear section ( 14 ) of said bench seat top ( 5 ) may be braced against. The bench seat may be constructed thereby in a simpler manner to hold a varying number of (required) seats since standard parts may be used at each side. Care and maintenance are simplified through the folding ability of the backrest and the bench seat top.
