Through the verification results show that the seat on both sides of inside and outside illustrates rotational displacement in the process of impact under different, large rotation Angle of the differences between each other led to unlock system is in unstable condition, transmission synchronization stem improper rotation leads to the driven side illustrates the unlock. Remove unlock system, such as synchronous rod seat backrest independently illustrates the strength test, the test sample does not appear to unlock phenomenon, the results conform to the requirements of the laws and regulations, unsafe unlock system is the main cause of test failure. To improve the illustrates unlock institutions, seat withstood the impact overall system, effectively resolves the problem of test failure. Keywords: manual illustrates, release system, dy
