Control mechanism for a chair
DCFirst Claim
1. A movable chair having a base adapted for movement across the surface on which the chair is situated, a seat member, a support member extending between the base and the seat member, the chair having a movable portion and a stationary portion to permit the reconfiguration of the chair, the chair comprising:
- (a) a mechanical actuator comprising an operating member positioned proximate a surface of the chair and having first and second arms, the second arm having an axis, the second arm receiving a force applied by a user at an angle to the axis of the second arm and transmitting the force to the first arm;
(b) a retaining member for retaining said moveable portion of the chair in either of at least two positions providing different configurations of the chair, said retaining member having an element moveable between a first position in which said moveable portion is moveable between said at least two positions and a second position in which the configuration of the chair is fixed;
(c) a mechanical coupling member having a first end connected to said first arm of said member and a second end operatively connected to said retaining member; and
,(d) a locking member actuated by operation of the mechanical actuator for alternately maintaining said retaining member in said first and second positionswhereby, movement of said second arm causes said first arm to move so that said retaining member is actuated and the moveable portion of said chair may be adjusted relative to the stationary portion.

Abstract
A seating unit comprises a support member; a seat member pivotally mounted on the support member; an arm rest member having an actuating button positioned in the arm rest member, the button being movable between a first position and a second position; a fluid pressure cylinder having actuating means and operatively connected to the seat member for adjustment of the inclination thereof; and, a flexible cable having a first end connected to the button and a second end operatively connected to the actuating member. When the button is moved from the first position to the second position, the actuation member is actuated so that the inclination of the back member or the seat member may be adjusted and when the button is moved from the second position to the first position, the inclination of the back member or the seat member is fixed.

11. A movable chair having a base adapted for movement across the surface on which the chair is situated, a seat member, an arm, a support member extending between the base and the seat member, the chair having a movable portion and a stationary portion, the chair comprising:
-
(a) a mechanical actuator positioned in the arm of the chair, said actuator being movable between a first position and a second position; (b) a retaining member for retaining said moveable portion of the chair in either of at least two positions providing different configurations of the chair, said retaining member having an element moveable between a first position in which said moveable portion is moveable between said at least two positions and a second position in which the configuration of the chair is fixed; (c) a mechanical coupling member having a first end connected to said mechanical actuator and a second end operatively connected to said retaining member; and
,(d) a locking member for alternately maintaining said element in said first and second positions whereby, when said actuator is moved from said first position to said second position, said retaining member is actuated so that the moveable portion of said chair may be adjusted relative to the stationary portion, and when said actuator is moved from said second position to said first position, the moveable portion of the chair is fixed relative to the stationary portion. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A movable chair having a base adapted for movement across the surface on which the chair is situated, a seat member, a support member extending between the base and the seat member, the chair having a movable portion and a stationary portion, the chair comprising:
-
(a) a mechanical actuator comprising a lever extending in a plane and a transmission element, said transmission element operatively engaging the lever to apply a force to the lever at an angle to the plane of the lever to move the lever between a first position and a second position by a force applied by the hand of a user while seated in the chair, said actuator including a locking member for alternately maintaining said lever in said first and second positions; (b) a retaining member for retaining said movable portion of the chair in either of at least two positions providing different configurations of the chair, said retaining member having an element that is releasable to permit said moveable portion to move between said at least two positions; and
,(c) a mechanical coupling member having a first end connected to said lever and a second end operatively connected to said retaining member whereby, when said lever is moved from said first position to said second position, said element is actuated so that the moveable portion of said chair may be adjusted relative to the stationary portion, and when said lever is moved from said second position to said first position, the moveable portion of the chair is fixed relative to the stationary portion. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
