Adjustable reclining chair

摘要

An adjustable reclining chair comprises a support frame (1, 2) and a seat which is pivotally mounted on the support frame so that it can swing about a pivot axis (12). A combined back and head rest (9) is fixed to seat portion (8), to which a leg rest (10) is articulated. The leg rest can be raised by extension of pneumatic ram (30) operated by a controller (34). A further pneumatic ram (20) acts between the support frame 1 and the back and head rest (9), and extension of this ram pivots the seat to an upright position in which the seat portion (8) is substantially horizontal. Catches (23) automatically engage to hold the seat in this position until they are released and a second controller (34) is operated to exhaust the ram (20), whereupon the seat tilts backwards to a reclined position. A cylinder of compressed air for supplying the rams (20) and (30) is carried on an extension (15) of the seat portion.
