The backrest is supported by the pair of limbs on which the the seat is pivoted. Armrests are independently mounted on the rail. The seat structure may also be pivotally mounted on the rail so that it can fold forwardly or backwardly to an out-of-use position and/or be directly mounted on retractable tiers to provide retractable seating.
