It is known for wheelchairs to have lateral pads for supporting the sides of the torso of a human user. It is convenient for the pads to be swung out of the way to enable the user easy access to the chair, and then swung back closer to the body and locked in place. It is an object of a preferred form of the invention to go at least some way towards achieving this. In a preferred form the invention there is a lateral support forming part of a seat, comprising a bracket 1, a hinge body 2, a forward plate 3 having padding and a lever 17. The lever 17 is arranged so it can be turned by hand to move a bolt 18 into a pin 5 whereby the hinge body is prevented from swinging about the pin. The lever 17 is also arranged so it can be subsequently turned by hand to cause a cam face 21 of the lever to ride along a complimentary engaging surface 22 of the hinge body. This forces the bolt 18 from the pin 5 thereby freeing the hinge body 2 to swing about the pin 5 and, as a consequence, to swing the plate 3 to facilitate access to the seat.
