The invention provides an impact buffer device for an automobile seat. The impact buffer device comprises a plurality of fixed plates, a plurality of movable plates, an elastic piece and a trigger device. The movable plates are located on the upper surfaces of the fixed plates and can horizontally move along the upper surfaces of the fixed plates. When the movable plates move horizontally relative to the fixed plates, the elastic piece can accumulate or release elastic potential energy. After the elastic piece accumulates elastic potential energy, the trigger device is started so that the elastic potential energy can be released, and the elastic potential energy can drive the movable plate to move relative to the fixed plate. The trigger device is connected with an automobile safety belt. The trigger device can be triggered by stretching the automobile safety belt. When an impact occurs on an automobile, the buffer device drives the automobile seat to move backwards rapidly, the chests and legs of passengers are prevented from being injured, and therefore safety of the passengers in the automobile is protected; meanwhile, the installation size of the buffer device can be adjusted so that the buffer device can be applicable to automobile seats of different sizes.
