A wheelchair (10) comprises a seat (12) defining a hole (14), so a user can use a toilet, and also comprises a mechanism (22) for lowering or raising the seat (12) relative to the wheelchair (10), and so relative to a toilet bowl, so that when lowered the underside of the seat locates within the toilet bowl. The mechanism (22) includes a handle (20) that moves support plates (34) in a generally horizontal plane, with inclined surfaces (32) to convert horizontal movement to vertical movement and to provide a mechanical advantage. |
