Abstract: A stairlift (12) comprises a carriage (10) moveable along a rail (14) by a drive means (18) and a seat (34) moveably coupled to the carriage. Levelling means are provided for altering the orientation of the seat with respect to the carriage. Further, limiting means (40) are provided for limiting movement of the seat with respect to the carriage so as not to exceed a predetermined angle of inclination of the seat, and comprising locking means (42). When the angle of inclination of the seat reaches the predetermined angle, the limiting means mechanically engages with the seat assembly to prevent further movement of the seat and operates the locking means to secure the seat in position.

Abstract: If a mobility aid develops a problem, the person controlling the aid may be unable to move or request assistance or call for help. Furthermore, even if someone was alerted to their predicament, that person may not be able to identify and thus rectify the problem expediently without expert assistance. A system (10) for monitoring for a fault in a mobility aid (12) includes a fault detector for detecting a fault in the mobility aid. The system also includes a signal generator (14) for generating a signal representative of the fault is also provided. A wireless transmitter (16) for transmitting fault signal, and a wireless receiver (18) for receiving the fault signal are also provided. The receiver is also operable for causing an alert to be sent to an operator that the mobility aid (12) requires attention.
