ABSTRACT:
A chair tilting mechanism (1) is disclosed which has a fixed support (2), a seat support (3) and a backrest support (4). The seat support (3) is pivotally connected to the fixed support (2) by a pivot pin (5). The backrest support (4) is pivotally connected to the seat support (3) by a pivot pin (6). There is additionally provided a link (7) connected by pivot pins (8,9) to the backrest support (4) and the seat support (2). Because of the link (7), rotation of either the backrest or seat support causes the other of the backrest or seat support to tilt in a pre-determined synchronised manner. The manner in which synchronised tilting occurs is set by the interconnection of the various parts. The invention also provides a means (41) for pre-setting the interconnection.
