Abstract:
A chair can include a chair back, or backrest, that is coupled to a base of a chair above a seat of the chair. A tilt mechanism can attach the backrest to the base at spaced apart locations. In some embodiments, the tilt mechanism can be configured so that the backrest rotates about multiple pivots as it reclines from an upright position to a reclined position to drive forward motion of the seat during recline of the backrest.

Claim (Index 20):
The chair of  claim 19 , wherein each of the backrest pivotal connections between vertically extending members of the backrest and vertically extending members of the housing comprises:\n a first axle extending from an upper end of the vertically extending member of the housing to the vertically extending member of the backrest of the backrest pivotal connection such that the backrest is rotatable about the first axle; wherein each of the seat pivotal connections between the projections of the backrest and the seat frame of the seat comprises:\n a second axle that extends through a slit defined in the projection of the backrest of the seat pivotal connection adjacent an aperture defined in the seat frame, the second axle pivotally connecting the projection of the backrest to the seat frame so that rotation of the projection that occurs when the backrest is moved from the upright position to the reclined position drives the seat frame forwardly; and \n wherein each of the seat connections comprises:\n a connector positioned within an elongated slot defined in the seat frame to attach the seat frame to the housing, a portion of the housing to which the connector is attached being a ramped portion so that the connector is inclined or declined within the slot to define an inclined or declined path of travel of the seat so that the seat moves upwardly or downwardly as the seat moves forwardly.
