Control assembly for chair

摘要

A control assembly for a chair including a base structure having a first pivot point and a second pivot point spaced from the first pivot point, a seat support structure pivotably coupled to the base structure for rotation about the first pivot point, a back support structure pivotably coupled to the base structure for rotation about the second pivot point, wherein the back support structure is adapted to rotate between a first and second positions, and a control link having a first end coupled to the seat support structure, and a second end coupled to the back support structure, wherein the control link rotates the seat support structure at a slower rate of rotation than a rate of rotation of the back support structure as the back support structure is rotated between the first and second positions.

1. A control assembly for a chair, comprising:
a base structure having a first pivot point and a second pivot point spaced from the first pivot point, wherein the base structure is adapted to attach to a ground-abutting base support structure; a seat support structure directly pivotably coupled to the base structure for rotation about the first pivot point, and wherein the seat support structure is adapted to support a seated user; a back support structure directly pivotably coupled to the base structure for rotation about the second pivot point, wherein the back support structure is adapted to rotate between a first position and a second position; and a control link having a first end operably coupled to the seat support structure, and a second end operably coupled to the back support structure, wherein the control link rotates the seat support structure at a rate of rotation slower than a rate of rotation of the back support structure as the back support structure is rotated between the first and second positions.
