[origin: EP0917843A2] A bed or chair with variable-position backrest, comprising a seat portion (2) and a backrest (3) which is hinged to the seat portion (2), about a substantially horizontal axis (4), proximate to the rear side of the seat portion. The bed or chair comprises a detent device (5) which is interposed between the seat portion (2) and the backrest (3) and is suitable to lock the backrest, in its rotation about its horizontal axis (4), in positions which lie at various angles with respect to the plane of arrangement of the seat portion (2). An elastic means (6) is provided which is interposed between the seat portion (2) and the backrest (3) and elastically contrast the rotation of the backrest (3) about its horizontal axis (4) in the direction of rotation that causes an increase in the angle formed by the backrest (3) with respect to the plane of arrangement of the seat portion (2). <IMAGE>
