Abstract
Tilt control for a back support and height control for the back support and a seat for a chair or the like are provided by a gas cylinder actuator having a cam surface and pivotally mounted so that the cam surface activates the gas cylinder. A blocker plate is pivotally mounted for movement between one position in which it prevents tilting of the back support and another position in which tilting is permitted. The actuator and blocker plate are coupled together so that pivotal movement of one is accompanied by pivotal movement of the other.
