Abstract
An adjustable chair seat with a locking mechanism is disclosed. The chair includes a seat pan, a seat plate and a torque limiting fastener. The seat pan and seat plate have openings for receiving the fastener which comprises a cup handle and a threaded insert. The threaded insert is engaged with the seat pan through an opening in the seat pan while the seat plate is sandwiched between the seat pan and the fastener. Once engagement is made, the fastener cannot be disengaged; and once a predetermined resistance is reached the cup handle slips relative to the threaded insert so as to cease the application of torque to the threaded insert.
Claims19
