发明名称 TILTABLE SWIVEL CHAIR
摘要 A tiltable swivel chair in which a seat is mounted on a pivot head for tiltable movement about a tilt axis which is normal to a vertical swivel axis. A housing which carries the pivot head also carries a series of compression washers engaging pins projecting from the pivot head to swing the latter forwardly around the tilting axis to a predetermined forward end position. The compression washers are distributed along a horizontal spring axis and the pins projecting from the pivot head compress the washers when the pivot head is swung rearwardly when the seat of the chair is tilted back. The tiltable swivel chair may also include compression washers distributed along a vertical spring axis and engaging stationary pins which project from the housing.
