1. A seat belt of a vehicle comprising:
- a cover made of a fabric material;
upper and lower webbings respectively fixed to opposite ends of the cover;
a D-ring fixed to the upper webbing and arranged within an occupant compartment of the vehicle;
a retractor fixed to the lower webbing to wind and unwind the lower webbing;
an air belt to rapidly supply a high-pressure gas into a bag held in the cover during a vehicle crash, and thus, to inflate the bag;
a dual inflator having two gas generating components which are configured to inject different amounts of gas, respectively; and
a level adjuster arranged in the occupant compartment to adjust a vertical level of the D-ring, the D-ring being mounted to the level adjuster such that the vertical level of the D-ring is adjustable in accordance with an operation of an occupant,wherein only the gas generating component configured to inject a greater amount than that of the other gas generating component injects gas when an impact level is less than a predetermined level, andwherein the level adjuster includes a fixed member fixedly mounted to a center filler, a movable member to carry the D-ring, a retractable locking member mounted in the movable member to protrude from the movable member, and a spring interposed between the movable member and the locking member to apply an elastic force to the locking member.

Abstract
A seat belt of a vehicle including an air belt to stably and reliably protect an occupant during a vehicle crash. The seat belt includes a cover made of a fabric material, upper and lower webbings respectively fixed to opposite ends of the cover, a D-ring fixed to the upper webbing and arranged within an occupant compartment of the vehicle, a retractor fixed to the lower webbing to wind and unwind the lower webbing; and an air belt to rapidly supply a high-pressure gas into a bag held in the cover during a vehicle crash, and thus, to inflate the bag. Since the bag is covered by the fabric cover, an improvement in wearing comfort is achieved.
