Abstract

An airbag apparatus to be applied to a vehicle includes an airbag, a collision determiner, and an airbag deployment controller. The airbag is configured to be deployed forward of a vehicle body front of the vehicle. The collision determiner is configured to establish a human-body pre-crash determination in a case where a collision probability with a human body is equal to or higher than a predetermined threshold. The airbag deployment controller is configured to deploy the airbag in response to the human-body pre-crash determination. The airbag includes a pulling member configured to pull and recess a front surface of the airbag rearward of the vehicle so as to form a slit portion configured to divide a front portion of the airbag.

Claims (39)

1. An airbag apparatus to be applied to a vehicle, the airbag apparatus comprising:

an airbag configured to be deployed forward of a vehicle body front of the vehicle;

a collision determiner configured to establish an object pre-crash determination in a case where a first collision probability with an object is equal to or higher than a predetermined threshold; and

an airbag deployment controller configured to deploy the airbag in response to the object pre-crash determination,

wherein the airbag comprises a pulling member configured to pull and recess a front surface of the airbag rearward of the vehicle so as to form a slit portion configured to divide a front portion of the airbag.

2. The airbag apparatus according to claim 1 ,

wherein the collision determiner is configured to establish an object pre-crash determination in a case where a second collision probability with a second object other than the object is equal to or higher than a second predetermined threshold, and

wherein the airbag deployment controller is configured to deploy the airbag in response to the object pre-crash determination,

the airbag apparatus further comprising a pulling member disabling unit configured to disable the pulling member pulling the front surface in response to the object pre-crash determination.

3. The airbag apparatus according to claim 2 ,

wherein the pulling member comprises a tether made of a flexible material, and

wherein the pulling member disabling unit comprises a tether cutter configured to cut the tether.

4. The airbag apparatus according to claim 1 , wherein the slit portion extends vertically and comprises a plurality of slit portions formed in the front surface of the airbag, the plurality of slit portions being distributed in a vehicle width direction.

5. The airbag apparatus according to claim 2 , wherein the slit portion extends vertically and comprises a plurality of slit portions formed in the front surface of the airbag, the plurality of slit portions being distributed in a vehicle width direction.

6. The airbag apparatus according to claim 3 , wherein the slit portion extends vertically and comprises a plurality of slit portions formed in the front surface of the airbag, the plurality of slit portions being distributed in a vehicle width direction.

7. The airbag apparatus according to claim 1 ,

Wherein the pulling member comprises a plurality of pulling members, and
