Abstract:
The invention provides an article of adjustable furniture (10), preferably an adjustable chair or bed, comprising a floor standing base section (16), adjustable seat (18), backrest (20) and headrest (130) sections and actuator means (100) for moving the backrest and headrest sections. The seat section is movably mounted with respect to the base section. The backrest is movably mounted with respect to the seat section and the headrest is movably mounted with respect to the backrest section. The actuator means includes a single actuator (102) for co-ordinated movement of the adjustable backrest and headrest sections for selectively altering the configuration of the article of furniture. The actuator has a first range of movement for moving the headrest with respect to the backrest, and a second range of movement for moving the backrest with respect to the seat section to provide a recliner function. The invention also provides an article of adjustable furniture comprising a backrest (20) and an adjustable headrest (130) pivotally mounted with respect to the backrest, actuator means (100) for moving the headrest between raised and lowered positions, and guide means arranged between the headrest and the backrest for rotating the headrest with respect to the backrest as it moves between said raised and lowered positions. The guide means includes first (138) and second (140) guides, each associated with one of the backrest and the headrest and having at least one follower (142, 144) associated with the other of the backrest and headrest. The first and second guides are inclined with respect to each other such that a turning moment is generated on the headrest when the headrest is raised or lowered.
