Abstract

The present invention describes and claims a friction drive stairlift (10) in which a stairlift carriage (11) is driven up and down a stairlift rail (12) by frictional inter-action between a drive member (25) located in the carriage (11), and the rail (12). Weight transfer means (38a, 38b, 44) are provided between a chair (13) and the drive member (25) to ensure that, when a downward load is applied to the interface (13) (as would be the case when a user mounts the stairlift) that downward force is applied to increase the frictional inter-action between the drive member (25) and the rail (12).
