Abstract

PURPOSE:To develop an air bag forward from a driver sufficiently at an early time even if the output of an inflator is small, by tearing at least one between the intermediate part of a strap and the connection part between the strap and the air bag basic cloth, by a prescribed pressure up to the completion of the development of the air bag. CONSTITUTION:In the vicinity of the front end of a strap 23, a thin width part 26 is formed on the strap 23 by forming cut-in parts 24 and 25 from the side of the strap 23. As for an air bag device for assistant driver's seat, when an inflator 15 is operated to develop an air bag 10, the air bag 10 is developed to an intermediate shape 10' at first, and the strap 23 is torn at the neck part 26, and the air bag 10 is developed to the final development shape. In the state where the air bag 10 is developed to the intermediate shape 10', the waist part of a driver is protected, and then the upper part of the air bag 10 is developed to form the final development shape, and also the upper part of the upper body of the driver can be protected sufficiently.

上半身の上部（胸や頭）も十分に保護できる。This intermediate-shaped airbag has already been inflated to some extent in front of the occupant and can protect the occupant, and in particular, can protect the lumbar region of the occupant early. Generally, in the case of a vehicle collision, the passenger's upper body moves as a whole toward the front of the vehicle, and then the upper part of the upper body falls forward of the vehicle with a slight delay. Therefore, when the airbag 10 is inflated like the intermediate shape 10 'in FIG. 4, the occupant's waist is protected, and then the upper portion of the airbag 10 is inflated to form the final inflated shape. The upper part of the chest (chest and head) can be well protected.
