Abstract (en)
[origin: WO9946198A1] A control arrangement for controlling the orientation of the seat assembly of a stair lift with respect to the chassis of the stair lift as the chassis moves along an inclined elongate rail. The control arrangement includes means for causing relative movement between the seat assembly and the chassis, such as, for example an electric motor. These means are then further controlled by control means such as an electronic circuit to ensure that the seat assembly is maintained in a horizontal orientation with respect to the ground. In addition, a stair lift rail construction arrangement is also disclosed wherein transitional sections of rail between rail sections of different inclines are formed as arcs of a circle. This allows the control means to be simplified as the electric motor need only be run at a constant rate to maintain the seat orientation during the transitional sections.
