Abstract: A wheelchair is described herein, including wheels, a support frame that engages with the wheels, a seat base fitted to the support frame, and suspension between the frame and the seat base, wherein the seat base is adapted to move with respect to the support frame when a human occupant is seated on the seat base such that the suspension dampens body weight force between the seat base and the support frame.

Abstract: A seat is disclosed herein having a backrest, a base for receiving a posterior of a human user, and an incline adjuster having a shaft, a lever, a follower, and a rack the shaft being moveable to swing the lever to cause a follower into or out of locking engagement with the rack, an arrangement being such that when the follower is in an unlocked disposition the rack can move to adjust an incline of the backrest and the base.

Abstract: The invention relates to means for releasably connecting a wheelchair backrest to a wheelchair frame. This is desirable to facilitate collapse of the wheelchair for transport or storage. In the preferred embodiment there is a wheelchair having a support frame, a backrest (16) and connector comprising a saddle (1) and a clamp (17). The saddle has a slot (3) with top and front openings and a locking lever (7). Two pins (12) are received in the slot so they extend through the front opening, and the lever (7) is able to move to divide the slot into top and bottom zones so that a lower one of the pins is prevented from being withdrawn from the slot via the top opening by the lever. The lever can then be moved to unblock the lower pin and allow the slot (3) and the pins (12) to be dissociated.
