The invention relates to a multi-stroke lightning protection seat energy absorption device with a self-resetting function. Comprising an upper connecting block, a box body, a reset mechanism, a steel belt limiting pin, a lower connecting block, a sawtooth steel belt, a steel belt limiting gear pin, a clamping jaw, a clamping jaw spring, a guide rail and an inverted-T-shaped connecting rod. The end of a vertical rod of the connecting rod is connected with the upper connecting block, a sliding rail groove is formed in a transverse rod on one side of the connecting rod, the guide rail and the box body are fixed, a gap for a sawtooth steel belt to pass through is formed between the sliding rail groove and a connecting rod body, and a clamping jaw is arranged at one corner, facing the guide rail, of the transverse rod of the connecting rod. The side, facing the clamping jaw, of the sawtooth steel belt is sawtooth-shaped, and the side, facing the guide rail, of the sawtooth steel belt is smooth. The two ends of the sawtooth steel belt are free ends, and the middle of the sawtooth steel belt sequentially passes through the triangular pins. The box body is connected with the lower connecting block, the lower connecting block is connected with the seat lower cross beam, and the upper connecting block is connected with the seat upper cross beam. The energy absorption device is simple in structure, easy to install, high in energy absorption efficiency and low in cost.
