Abstract
Abstract An airbag device including an airbag that provides more effective protection of an occupant. The airbag has an indentation located approximately in the center of a contact surface thereof. The indentation is formed in the shape of a recess or a valley to form the airbag into a heart-like shape. The area including the indentation is at least greater than an area where comes in contact with the face of an occupant. The deepest point of the dent (the farthest point from the occupant in the contact surface) is positioned below the jaw of the occupant. The contact surface extending from the deepest point of the dent to the upper projection top thereof overhangs toward the occupant to have an angle between 0° and 45° (preferably, between 15° and 25°) relative to the cervical vertebrae axis of the occupant.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
130 words
An airbag device for protecting an occupant of a vehicle having an instrument panel comprising: an airbag including a middle panel having a front face with upper and lower portions, and being configured to be housed in an upper portion of the instrument panel, the airbag being adapted to be inflated and deployed toward the front of the occupant in the case of an emergency; wherein the middle panel is connected between a pair of side panels; and wherein each of the panels include adjacent cutout portions so that the connected panels form an indentation positioned to maintain the airbag in the shape of a heart when the airbag is inflated; wherein an area of the front face including the indentation is greater than an area of the upper portion.
Claim 2
Dependent Claim
130 words
An airbag device for protecting an occupant of a vehicle having an instrument panel comprising: an airbag including a middle panel having a front face with upper and lower portions, and being configured to be housed in an upper portion of the instrument panel, the airbag being adapted to be inflated and deployed toward the front of the occupant in the case of an emergency; wherein the middle panel is connected between a pair of side panels; and wherein each of the panels include adjacent cutout portions so that the connected panels form an indentation positioned to maintain the airbag in the shape of a heart when the airbag is inflated; wherein an area of the front face including the indentation is greater than an area of the upper portion.
Claim 3
Dependent Claim
21 words
The airbag device of claim 1 , wherein the indentation is formed in the shape of a valley in the airbag.
Claim 4
Dependent Claim
147 words
An airbag device for protecting an occupant of a vehicle having an instrument panel comprising: an airbag configured to be housed in an upper portion of the instrument panel, the airbag including a front face for contacting the occupant when the airbag is inflated or deployed in the event of emergency; wherein the front face of the air bag includes an upper portion and a lower portion and a cutout portion formed between the upper and lower portion so that when the front face is connected between a pair of side panels and the airbag is deployed an indentation is formed in the front face; and wherein the upper portion includes a contact surface that is configured so that when the airbag is deployed in the event of emergency the contact surface inclines toward the occupant as the contact surface extends upwards away from the lower portion.
Claim 5
Dependent Claim
147 words
An airbag device for protecting an occupant of a vehicle having an instrument panel comprising: an airbag configured to be housed in an upper portion of the instrument panel, the airbag including a front face for contacting the occupant when the airbag is inflated or deployed in the event of emergency; wherein the front face of the air bag includes an upper portion and a lower portion and a cutout portion formed between the upper and lower portion so that when the front face is connected between a pair of side panels and the airbag is deployed an indentation is formed in the front face; and wherein the upper portion includes a contact surface that is configured so that when the airbag is deployed in the event of emergency the contact surface inclines toward the occupant as the contact surface extends upwards away from the lower portion.
Claim 6
Dependent Claim
128 words
An airbag device for protecting an occupant of a vehicle comprising: an airbag adapted to be housed in an upper portion of an instrument panel, the airbag including a front face that contacts the occupant when the airbag is inflated or deployed in the event of emergency; wherein the front face includes an upper portion, a lower portion, and a cutout portion formed between the upper and lower portion so that when the front face is connected between a pair of side panels and the airbag is deployed an indentation is formed between the upper portion and the lower portion, the front face having a surface inclined toward the occupant, the inclined surface extending from a bottom of the indentation towards the upper portion of the front face.
