Chair and chair control assemblies, systems, and methods
First Claim
1. A method of actuating a chair control assembly of a chair, the chair control assembly including a seat support, a link arm, and a control body, the method comprisingrotating a body of the link arm in a first direction about a first pivot which causes a pivot link of the link arm to rotate in a second direction that is opposite to the first direction about a second pivot;
- in response to rotating the body of the link arm in the first direction, moving front riders and rear riders slidably coupled to the seat support and the control body upwardly and rearwardly in front channels and rear channels; and
in response to moving the front and rear riders upwardly and rearwardly in the front and rear channels, moving a seat mount of the seat support upwardly and rearwardly from a first lowered support position to a second raised support position such that a front of the seat mount is raised to a relatively greater extent than a rear of the seat mount.

8. A method of assembling a chair, the method comprising:
-
assembling a chair control assembly, the chair control assembly comprising a seat support, a link arm, and a control body; and coupling the chair control assembly to a back and a base of the chair such that rotating a body of the link arm in a first direction about a first pivot which causes a pivot link of the link arm to rotate in a second direction that is opposite to the first direction about a second pivot; wherein rotation of the body of the link arm in the first direction causes front riders and the rear riders slidably coupled to the seat support and the control body to move upwardly and rearwardly in front channels and rear channels causing a seat mount of the seat support to move upwardly and rearwardly from a first lowered support position to a second raised support position such that a front of the seat mount is raised to a relatively greater extent than a rear of the seat mount. - View Dependent Claims (9, 10, 11, 12, 13, 14)
