The invention provides a seat framework backrest restoring force test device which comprises a base, a support and a test execution device. The bottom end of the support is arranged on the base. The test execution device is arranged at the top end of the support, and comprises a base body, a connecting piece and an execution arm. The rear end of the base body is connected with the support. A backrest lock mechanism is arranged in the middle of the base body. The front portion of the base body is fixedly connected with the upper end of the connecting piece. The lower end of the connecting piece is fixedly connected with the middle of the execution arm. A speed control air cylinder is arranged at one end of the execution arm. A pressure sensor is arranged at the other end of the execution arm. A mechanism action air cylinder is arranged on the side face of the connecting piece and connected with the pressure sensor. The seat framework backrest restoring force test device guarantees the movement start point and ending point of a backseat and the pushing strength and speed, testing is finished automatically, unstable factors of manual testing are avoided, testing efficiency is improved, and testing result accuracy is guaranteed.
Description
