The invention discloses an airbag safety system for increasing the friction coefficient of an automobile seat and aims at providing the airbag safety system. According to the airbag safety system, the surface of the seat can obtain higher surface friction coefficient and the buffer and constrain actions of the automobile seat to passengers are enhanced when an automobile meets with front collision under the condition of not influencing the sitting comfortableness, and thus the safe performance of the front collision of the automobile is improved and the friction coefficient of the automobile seat is increased. The airbag safety system comprises a gas generation device and an airbag layer which is paved on the surface of a seat cushion of the seat; a hard isolating layer is arranged between the airbag layer and the seat cushion of the seat; the airbag layer is provided with a plurality of transverse sub airbags which are arranged side by side; each transverse sub airbag extends along the lateral direction of the seat; the gas generation device is communicated with each transverse sub airbag through a gas-guiding tube; and the gas generation device is connected with an ACU (Automatic Calling Unit) of the automobile safety airbag system through a signal wire.
