Abstract
An article of furniture such as a chair (10) includes a seat member (13), a back member (11) pivotally attached to the seat member (13), leg members (14,16) attached to the seat member (13), and arm members (20) attached to the back member (11). The arm members (20) are associated with the leg members (14,16) such that the angular relationship between the seat member (13) and the back member (11) may be adjusted to a plurality of positions. A track system (26) defines a plurality of adjacent stop positions (29) with a pin member (46) interacting with the track system(26) to engage a stop position (29) therealong. The track system (26) is configured so that upon relative movement of the track system (26) and the pin member (46), the pin member (46) engages the next adjacent stop position (29) thereby moving the back member (11) with respect to the seat member (13 ) only to the next adjacent plurality of relative angular positions.
