A swivel assembly 14 for use with a stairlift chair comprises first 22 and second 23 axes of rotation parallel to each other and spaced apart in a perpendicular direction. At least one of the axes of rotation 22, 23 may be defined by a shaft. The shaft may be located in a common housing 27 and project from the housing 27 in opposite directions. There may be a transmission 24, 25, 26 by which rotation about one of the axes 22, 23 affects rotation about the other axis of rotation 22, 23. The swivel assembly 14 may be mounted to a stairlift carriage 11 along the first axis 22 and may be mounted to a stairlift chair 13 along the second axis 23. The chair 13 may have a longitudinal centre line 20 between front and rear edges 18, 19 and the second axis 23 may be fixed to the chair 13 along this line. The swivel assembly 14 can be used to facilitate mounting and dismounting of the stairlift chair without causing collision with the wall 31 of the staircase. |
