Abstract
According to various embodiments, there may be provided a back-support assembly for a chair. The back-support assembly may include a back-support mounting frame and a displaceable member that is displaceable relative to the back-support mounting frame. The back-support assembly may further include a motion converter that operatively couples the displaceable member to the back-support mounting frame. The motion converter may be configured to convert an input motion applied to the motion converter into an output motion that displaces the displaceable member along the primary movement axis. The back-support assembly may further include a link arrangement for coupling one or more back-support members to the displaceable member, the link arrangement being operatively engaged with the displaceable member so as to be movable relative to the displaceable member along a secondary movement axis that is non-parallel to the primary movement axis.
