The present invention relates to a center hinge assembly of a rear seat back for a vehicle. The present invention provides the center hinge assembly of the rear seat back for the vehicle, composed of a rear seat back frame and a hinge bracket fixated in a chassis wherein the rear seat back frame includes a hinge shaft fixated in the hinge bracket to be able to rotate and a hinge bush inserted around the hinge shaft, which is formed to protrude an internal low friction unit for reducing friction with the hinge shaft on an inner diameter of the hinge bush, and is formed to protrude an external low friction unit for reducing friction with the hinge bracket on an outer diameter of the hinge bush. The present invention minimizes a friction connection when the rear seat back frame is folded, thereby enhancing a riding environment and increasing user convenience. |
