Abstract: PURPOSE: An airbag cushion for protecting a pedestrian is provided to maximize the performance for protecting the pedestrian by preventing the initial pressure of airbag gas, which is sprayed from an inflator, from being directly delivered. CONSTITUTION: An airbag cushion for protecting a pedestrian comprises a main cushion(20), a dispersion pocket(30), and a tether(40). The internal space of the main cushion is comprised of a plurality of division chambers(22). An inlet(31) and a plurality of gas discharging units(32) are integrally equipped to the dispersion pocket. The inlet receives the airbag gas from an inflator(1). The gas discharging unit discharges the airbag gas to the division chamber. Both ends of the tether are connected to the main cushion and prevents the main cushion from flowing.
