Abstract

See full text

The specification discloses a synchrotilt chair control in which a slide is provided between the front of the seat support and stationary control housing, which slide serves not only to make possible synchrotilt action between the back support and seat support, but also makes possible the incorporation of a seat adjustment assembly. The latter comprises a pivot bracket pivotally mounted on the slide and on the seat support, and an actuator for pivoting the pivot bracket. The pivotal mounting between the seat support and back support is also dual functional in that it supports a pivotally mounted lock plate for locking the control. A height adjustment actuator and hidden handle pretension adjustment bolt are also provided.
