A wheelchair (10) wheel bracket (60) comprises a first part to be fixated to the frame of the wheelchair (10) and defines a first set of opposite first and second contact surfaces. The first part is repositionable relative to the frame for allowing the first contact surface, or alternatively, the second contact surface to face outwardly relatively to the frame defining a fixation surface. The bracket further comprises a second part supporting the wheel shaft (50) of one of the wheels (44, 45) and defining a second set of opposite third and fourth contact surfaces for allowing the third contact surface, or alternatively, the fourth contact surface to be contacted with and fixated relative to the fixation surface. At least one of the first and second sets of opposite contact surfaces defines a non parallel set of contact surfaces and at least one combination of contacting one of the surfaces of the second set with one of the surfaces of the first set providing a non cambered position of the wheel, and a different combination of contacting one of the surfaces of the second set with one of the surfaces of the first set providing a positive cambered position of the wheel. |
