Abstract

A chair has a back (2) and a seat part (1), which are pivoted at an axis (8), and to a fixed body (5) at a main pivot (7). An arm (16) is connected to the axis (8) by a link which is displaced by pivoting of the back (2), thereby moving the (arm16) reciprocally. The other end of the arm (16) is connected to a secondary pivot (15), which orbits the main pivot (7) on a further link. Main pivot (7) carries a latch (14) which is adapted to engage withstepped detents (21) on the upper edge of arm (16), while secondary pivot (15) carries a second latch (13) which is adapted to engage with stepped detents (18) formed in the base of body (5). The (arm16) is displaced by rotation of the link to pivot (8) so that latch (14) can engage with different ones of the detents (21), and at the same time displaceable latch (13) to engage with different ones of the fixed detents (18). Respective pivoted bell-crank levers (11) and (12) are also pivoted on axis (8), and have first respective ends which bear on respective latches (13 and 14), and second ends which bear a (cam10) carried on an axis which can be turned by a handle, to engage or disengage the latches. A tilt limiting device is provided by latch (13,14) engaging with stepped detents (119).
