A transport seat for conveying disabled travellers through a stairwell opening of a passenger carrying vehicle is disclosed. An elongate boom section is pivotally connected to a support base located exterior of the vehicle and is intended to extend over the stairwell of the vehicle. The boom section at its vehicle interior end is supported from the floor or a stair tread of the vehicle. A seat is carried on the boom section and is reciprocatable therealong. A traveller on the seat, during transport, faces outwardly of the vehicle towards the support base. The seat, however, is made rotatable so that a traveller on the seat, after being transported into the interior of the vehicle, can be rotated in a horizontal plane in order to face the vehicle floor and leave the seat and conversely, can first occupy the seat and then be rotated to face the support base before being transported from the interior of the vehicle. Because the vertical angle of the boom may vary, the seat carried on it is made adjustable so that it remains in a substantially horizontal plane during use. The support base can be located at a fixed position, or optionally, roller mounted for portability. The device is principally intended for use with passenger coaches but can also be employed when transporting disabled travellers to and from trains and aircraft. No structural or mounting alterations to the passenger carrying vehicle are required.
