The one shell carries a cushion and forms therewith the seat of the chair. The other shell is assembled of two sections which are pivotable relative to each other about a horizontal axis, one of which supports the lumbar region of the body of the occupant of the chair and the other of which serves as a shoulder support. The one section is articulately connected to the rear portion of the one shell by two hinges.
