A vehicle occupant restraint system of the present invention has: a seat belt restraint device ( 13 ) including a shoulder belt ( 11 ) which restrains the body of a vehicle occupant (C) diagonally from one of the shoulders (Cs) to the chest (Cc), and a lap belt ( 12 ) which restrains the waist (Cw) of the vehicle occupant (C); an upper air bag ( 30 ) supported by an upper support point ( 32 ) provided on the shoulder belt ( 11 ); a lower air bag ( 31 ) supported by a lower support point ( 33 ) provided on the lap belt ( 12 ) and coming into contact with the upper air bag ( 30 ) in a vertical direction when being inflated and extended; and an air bag movement inhibiting structure (H 1 -H 9 ). The air bag movement inhibiting structure (H 1 -H 9 ) applies, to at least one of the upper support point ( 32 ) and the lower support point ( 33 ), a moment (M 1 -M 13 ) in a direction of canceling movements of contact surfaces of the upper and lower air bags ( 30, 31 ) toward a side in the vehicle width direction, where a part of the shoulder belt ( 11 ) is located above the shoulder (Cs) of the vehicle occupant (C), when the upper air bag ( 30 ) and the lower air bag ( 31 ) receive inertial force of the vehicle occupant (C) toward a front of a vehicle.
