<p>A reclining or tilting chair comprises a seat recline mechanism 30 for controlling the motion of a seat portion relative to a support structure. The mechanism comprises first and second bearing means 32 for attaching to a first assembly, and a hub 31 for attaching to a second assembly. The hub includes first and second inclined surfaces (figure 9, 31a, 31b) oppositely-facing each other. In use, the first bearing means (figure 9, 32b) is arranged to act against the first inclined surface and the second bearing means (figure 9, 32c) is arranged to act against the second inclined surface, the relative positions of the first and second bearing means with respect to the first and second inclined surfaces is adjustable. In a preferred embodiment, third bearing means (figure 32d) acts on a third surface (figure 9, 31c) of the hub, the shape of which limits the extent at which the seat portion may recline. An incline angle locking mechanism and adjustable leg and back rests are also provided. Further disclosed is a seating assembly comprising one or more seat recline mechanisms, and also a method of controlling the motion of a first assembly relative to a second assembly within a seating assembly.</p> |
