Title: Control mechanisms for lockable joints to set angle of chair back - enable back to move through limited arc when unlocked
IPC: G05G5/12
Filed: 1973-04-10
Abstract: Control mechanisms of several types are used for the unlocking and locking of a joint which can rotate in the unlocked state through a limited arc only. One such joint is that which sets the slope of the back on an adjustable chair or a car seat. One such control mechanism is actuated by moving a lever 33 in the direction of the arrow f1. This causes the lever 24 to pivot round the axis 26 against the spring 32. The pivot action is guided also by the slot passing round the controlled axle 10. The movement shifts another lever 28 round a button 29 resulting in the normal teeth and crown joint, not shown, being freed. Another method claimed uses cams, and a third uses segments of interacting gears to produces the same result.
