Abstract (en)
[origin: US4763950A] To permit backward rocking of the back or back-and-seat of a chair, independently of the previously tilted-back position of the chair, a comfort position memory structure is provided which includes a manually adjustable variable stop structure formed by a cam curve (37) with a serrated or toothed surface, engaged by a stop element (41) coupled to the seat (17, 19). The cam (37) is manually rotatable, by being secured to an externally user-accessible adjustment segment (45). To set a predetermined tilted position, the user tilts back on the chair, and then permits the chair to tilt forward to a comfortable position, and then rotates the manually engageable segment (45) until a tooth (39) of the cam disk (37) is engaged by the stop (41). A spring (32) biasses the chair forwardly and against the stop, unless tilted back by the user.
