Abstract
An airbag includes: a base chamber; a left-half airbag inflated on a front-left side of the passenger, wherein a first opening is formed through the left-half airbag at an upper portion thereof; and a right-half airbag inflated on a front-right side of the passenger, wherein a first opening is formed through the right-half airbag at an upper portion thereof. A recess is formed between the left-half airbag and the right-half airbag so as to face the passenger, when the airbag is inflated in front of the passenger. The first openings are communicated with each other. A first seam joining the left-half airbag and the right-half airbag is formed to surround the first openings. The first openings communicated with each other are formed to extend in a vehicle front-rear direction.

An airbag which is inflated rearward from an instrument panel of a vehicle to come close a passenger seated in a passenger seat, the airbag comprising:
- a base chamber which is disposed at a front side of the vehicle;
- a left-half airbag which is continuous with the base chamber and is inflated on a front-left side of the passenger, wherein a first opening is formed through the left-half airbag at an upper portion thereof;
- and
- a right-half airbag which is continuous with the base chamber and is inflated on a front-right side of the passenger, wherein a first opening is formed through the right-half airbag at an upper portion thereof;
- wherein a recess is formed between the left-half airbag and the right-half airbag so as to face the passenger, when the airbag is inflated in front of the passenger,
- wherein the first opening of the left-half airbag and the first opening of the right-half airbag are communicated with each other,
- and
- wherein the first openings of the left-half airbag and the right-half airbag communicated with each other are formed to extend in a vehicle front-rear direction,
- wherein the first openings are formed in an elongated shape with a length in a longitudinal direction that is greater than a maximum width in a direction perpendicular to the longitudinal direction, and
- wherein a ratio of the length of the first openings in the longitudinal direction to a maximum width of the first openings in the direction perpendicular to the longitudinal direction is in a range of about 2 to about 10, when the airbag is not inflated.
A vehicle comprising an airbag apparatus, the airbag apparatus comprising:
- an airbag which is inflated rearward from an instrument panel of the vehicle to come close a passenger seated in a passenger seat, the airbag comprising:
- a base chamber which is disposed at a front side of the vehicle;
- a left-half airbag which is continuous with the base chamber and is inflated on a front-left side of the passenger, wherein a first opening is formed through the left-half airbag at an upper portion thereof;
- and
- a right-half airbag which is continuous with the base chamber and is inflated on a front-right side of the passenger, wherein a first opening is formed through the right-half airbag at an upper portion thereof;
- wherein a recess is formed between the left-half airbag and the right-half airbag so as to face the passenger, when the airbag is inflated in front of the passenger,
- wherein the first opening of the left-half airbag and the first opening of the right-half airbag are communicated with each other, and
- wherein the first openings of the left-half airbag and the right-half airbag communicated with each other are formed to extend in a vehicle front-rear direction,
- wherein the first openings are formed in an elongated shape with a length in a longitudinal direction that is greater than a maximum width in a direction perpendicular to the longitudinal direction,
- wherein a ratio of the length of the first openings in the longitudinal direction to a maximum width of the first openings in the direction perpendicular to the longitudinal direction is in a range of about 2 to about 10, when the airbag is not inflated,
- a retainer which houses the airbag which is folded up therein;
- and
- an inflator configured to inflate the airbag.
