The invention relates to a connection structure of an automobile seat, in particular to a power-absorbing structure of the automobile seat, which can deform in the collision process. The power-absorbing structure solves the problem that the necks of passengers in rear-end vehicles are easy to sprain during rear-end collision. The power-absorbing structure comprises a seat harness and a seat cushion, wherein the bottom ends at both sides of the seat harness are respectively installed at the rear ends of both sides of the seat cushion through a connecting board. The power-absorbing structure ischaracterized in that the lower side of the connecting board is provided with a front installing pin and a back installing pin, wherein the front installing pin is hinged on the seat cushion, and theback installing pin is installed on the seat cushion through a buffer power-absorbing device. When the rear-end collisions happens, the power-absorbing structure can deform to absorb power through the buffer power-absorbing device so as to protect the safety of the passengers and avoid spraining the necks of the passengers.
