Abstract
An article of furniture having a seat of a generally constant orientation but a back which can be tilted at various angles has a generally X-shaped relationship of the seat and back and, on each side a pair of horizontally spaced pins, affixed to the seat, one of which rides on the upper surface of a cooperating member of the back while the other can be selectively fitted into notches of a rack structure on the lower edge of the respective member. The upper edge or surface of these members have a cam configuration and the distance separating this edge from the bottoms of each of the respective notches is progressively increased downwardly along the rack so that the seat inclination is substantially constant for all positions in which the pins engage the notches.
