Pivoting swing seat with control system

摘要

A swingable and pivotable seating system includes a base portion, a swing arm, a seat and a control system. The swing arm is pivotable about a generally vertical first pivot axis and has a first end pivotally mounted at the base portion and a second end opposite the first end. The seat is pivotally supported at or near the second end of the swing arm and pivotable about a generally vertical second pivot axis. The control system controls pivotal movement of the seat about the second pivot axis responsive to a degree of pivoting of the swing arm about the first pivot axis. The seating system may include a desk portion, and the control system may limit pivotal movement of the seat when the seat is near the desk portion and may allow greater pivotal movement of the seat when the seat is swung away from the desk portion.

主权项

1. A swingable and pivotable seating system comprising:
a desk portion; a base portion generally fixed relative to said desk portion; a swing arm having a first end pivotally mounted at said base portion and a second end opposite said first end, wherein said swing arm is pivotable about a generally vertical first pivot axis to move said seat towards and away from said desk portion; a seat pivotally supported at said second end of said swing arm and pivotable about a generally vertical second pivot axis; wherein said swing arm pivots said seat between a stowed position, where said seat is disposed generally at said desk portion, and an opened position, where said seat is moved away from said desk portion; a control system that controls pivotal movement of said seat about said second pivot axis responsive to a degree of pivoting of said swing arm about said first pivot axis; wherein said control system limits pivotal movement of said seat to a varying range of pivotal movement of said seat about said second pivot axis that varies responsive to the degree of pivoting of said swing arm about said first pivot axis; and wherein said control system controls the range of pivotal movement of said seat about said second pivot axis throughout the full range of pivotal movement of said swing arm about said first pivot axis and without user selection of the range of pivotal movement of said seat about said second pivot axis.
