Combined tension and back stop function for seating unit |
摘要 |
<p>A seating unit (20) includes a base (21), a seat (22), a back (23), and a control (24) operably supporting the seat and the back on the base for movement between upright and recline positions. The control includes a spring (137) providing a biasing supporting force to the back during recline, and further includes a booster mechanism (25) capable of increasing the supporting force, and still further includes a selector device (155) for activating and deactivating the booster mechanism. The selector device is easily moveable with a low effort that is separated from and independent from any friction generated by internal components of the booster mechanism. In a narrower aspect, the control is powered, such as by an electrical or electromechanical device from a remote location. A back stop is attached to the selector device, for movement between a disengaged position, a partial-recline position, and a recline-prevented position.</p> |
