Abstract
An interlocking mechanism for a seat and a back of a chair is provided. A seat body and a chair chassis are pivotally connected, and a pad plate is pivotally connected with the seat body. Thereby the pad plate is moved around a pivotal connection between itself and the seat body when users sit on the pad plate. While a front side of the pad plate is moved downward, it is inclined to an angle slowly by a pad spring connected with the pad plate. When the use is leaning on the chair back connected with the seat body, the seat body is moved backward with a pivotal connection between itself and the chair chassis. The pivotal connection between the seat body and the pad plate can push the pad plate upward so that the seat body is inclined with the chair back and the user sits more comfortably.
