The present invention provides a test dummy for maintaining the spinal morphology of an automobile seat, belonging to the technical field of automobile seat test devices. The dummy comprises a prosthetic buttocks and a prosthetic back. The position of the prosthetic buttocks is adjusted by weights and fine-tuning weights. The fine-tuning weights are uniformly placed in a weight box. The prosthetic buttocks position is adjusted to meet the requirements of different seat positions by using small weights in the weight box, thereby increasing the universality of the dummy. The position of the prosthetic back is determined by the position of the prosthetic buttocks. The prosthetic back is divided into three parts according to the distribution of human bones and the degree of freedom law in the theory of kinematic mechanics, namely, a first part that simulates the human sacrum and the fourth and fifth lumbar vertebrae; a second part that simulates the first to third lumbar vertebrae and the seventh to twelfth thoracic vertebrae; and a third part that simulates the first to seventh thoracic vertebrae. Each part is designed with weights and graded damping for controlling the relative angles between the prosthetic backs, thereby simulating or measuring the state parameters of the automobile seat maintaining the real human spine.
