Vehicle occupant restraint system and vehicle occupant restraint method
First Claim
1. A vehicle occupant restraint system, comprising:
- a seat belt restraint device including a shoulder belt which restrains the body of a vehicle occupant diagonally from one of the shoulders to the chest, and a lap belt which restrains the waist of the vehicle occupant;
an upper air bag supported by an upper support point provided on the shoulder belt;
a lower air bag supported by a lower support point provided on the lap belt and coming into contact with the upper air bag in a vertical direction when being inflated and extended; and
an air bag movement inhibiting structure which applies, to at least one of the upper support point and the lower support point, a moment in a direction of canceling movements of contact surfaces of the upper and lower air bags toward a side in the vehicle width direction, where a part of the shoulder belt is located above the shoulder of the vehicle occupant, when the upper air bag and the lower air bag receive inertial force of the vehicle occupant toward a front of a vehicle.

Abstract
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 (H1–H9). The air bag movement inhibiting structure (H1–H9) applies, to at least one of the upper support point (32) and the lower support point (33), a moment (M1–M13) 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.

15. A vehicle occupant restraint method, comprising:
-
preparing;
a seat belt restraint device including a shoulder belt which restrains the body of a vehicle occupant diagonally from one of the shoulders to the chest and a lap belt which restrains the waist of the vehicle occupant;
an upper air bag supported by an upper support point provided on the shoulder belt; and
a lower air bag supported by a lower support point provided on the lap belt; andallowing the upper support point and/or the lower support point to generate a moment in a direction of canceling movements of contact surfaces of the upper and lower air bags toward a side in a vehicle width direction, where a part of the shoulder belt is located above the shoulder of the vehicle occupant, when the upper air bag and the lower air bag receive inertial force of the vehicle occupant toward a front of a vehicle.

16. A vehicle occupant restraint system, comprising:
-
a seat belt restraint device including a shoulder belt which restrains the body of a vehicle occupant diagonally from one of the shoulders to the chest, and a lap belt which restrains the waist of the vehicle occupant; an upper air bag supported by an upper support point provided on the shoulder belt; a lower air bag supported by a lower support point provided on the lap belt and coming into contact with the upper air bag in a vertical direction when being inflated and extended; and air bag movement inhibiting means for applying, to at least one of the upper support point and the lower support point, a moment in a direction of canceling movements of contact surfaces of the upper and lower air bags toward a side in a vehicle width direction, where a part of the shoulder belt is located above the shoulder of the vehicle occupant, when the upper air bag and the lower air bag receive inertial force of the vehicle occupant toward a front of a vehicle.
