The small air bag of the existing passenger seat safety air bag device can not provide effective safety protection for passengers who are not fastened with safety belts, and the heads of the passengers who are not fastened with the passenger seat safety air bag device can collide with windshields to cause serious injuries. The neck and chest of a passenger are injured and aggravated due to overlarge rigidity of the large air bag, and the large air bag cannot well protect a passenger in a copilot from being injured in the automobile collision.

The new energy vehicles exported to the United states need to meet the standards of the three major regulations of the United states crash safety regulations FMVSS208, U.S. NCAP and IIHS. In the U.S. regulations, the copilot occupants include 4 different situations, namely belted and unbelted, and two different body size weight dummies, 50% male and 5% female.

Based on the risks, the copilot airbag is designed according to the American regulatory standard, and can simultaneously meet 4 working conditions that a copilot passenger is not belted and the copilot passenger is 50-percentile male and 5-percentile female dummy in the United states FMVSS208 and U.S. NCAP frontal collision regulations.

It should be noted that the 50-percentile male and the 5-percentile female dummy may be the Hybrid III 50-percentile male dummy and the Hybrid III 5-percentile female dummy which are most commonly used in the car crash test.

Referring to fig. 1 to 3, a passenger airbag apparatus 100 according to an embodiment of the present invention includes a gas generator 10 and an airbag 20, the airbag 20 being in an inflated and deployed state after the gas generator 10 is inflated, the airbag 20 being configured such that in the inflated and deployed state of the airbag 20, the airbag 20 has a gap between the test dummy 200 seated on a passenger seat 300 and the vehicle 1000 when the vehicle does not collide.

The airbag 20 of the front passenger airbag device 100 according to the embodiment of the present application can be inflated and deployed by the gas generator 10, the inflated and deployed airbag 20 has a gap with the test dummy 200 sitting still on the front passenger seat 300 when the vehicle 1000 is not in collision, and the gap between the airbag 20 and the test dummy 200 allows the airbag 20 to be fully inflated and to be in direct contact with the test dummy 200 when the vehicle 1000 is in collision, so that the airbag 200 can effectively provide a protective support for the test dummy 200, and can reduce the injury to the passenger in an actual scene.

Specifically, the passenger airbag device 100 may be accommodated in the case 500, and the case 500 may be made of a rigid material. The passenger airbag device 100 can be fixed in the tube beam 600 and the instrument panel 700 on the passenger side by the mounting bracket when not expanded and deployed. When the vehicle 1000 is impacted, the passenger airbag apparatus 100 is deployed in conformity with the instrument panel 700, protecting the passenger in the passenger seat 300 and preventing the passenger from being impacted forward on the instrument panel 700 or the front windshield 400.

The gas generator 10 may be a device connected to the airbag 20 for filling the airbag 20 with gas. The airbag 20 receives the gas from the gas generator 10 and expands to have a three-dimensional shape between the front windshield 400 and the a-pillar 800 of the vehicle 1000. When the vehicle 1000 is hit, the airbag 20 is inflated and deployed from inside the instrument panel 700 toward the sub-driver in the instrument panel 700. The outer surface of the bag 20 may partially contact the front windshield 400 and the instrument panel 700, and the bag 20 may be inflated and expanded along the surface of the instrument panel 700. When the airbag 20 is inflated and deployed naturally in the non-impact state of the vehicle 1000, the outer surface of the airbag 20 has a gap from a dummy seated in the front passenger seat 300. The gap ensures that the airbag 20 will deploy in a collision when the vehicle 1000 is impacted and will not be harmful to a normally seated occupant.

It should be noted that the shape of the airbag 20 according to the embodiment of the present invention is designed to meet the standards of the collision safety regulations of FMVSS208\ u.s.ncap in the united states. Among them, the test dummy 200 may be a Hybrid III 50 percentile male dummy and a Hybrid III 5 percentile female dummy which are most commonly used in the car crash test.

In the collision test of the vehicle 1000, the position of the test dummy 200 may be such that the front passenger seat 300 is in the middle position between the front and rear adjustable positions in the horizontal direction and the height direction is in the lowermost position between the up and down adjustable positions when the 50 percentile male dummy sits still on the front passenger seat 300. The front-rear adjustment may be such that the passenger seat 300 can be adjusted front-rear with respect to the instrument panel 700, and the up-down adjustment may be such that the passenger seat 300 can be adjusted up-down with respect to the floor of the vehicle 1000.

Referring to fig. 1-3, in certain embodiments, the airbag 20 is configured such that the airbag 20 rests against a front windshield 400 when the airbag 20 is in an inflated, deployed state.

In this manner, the airbag 20 is in the inflated and deployed state, the airbag 20 abuts against the front windshield 400, and the front windshield 400 can provide support for the airbag 20, protect the test dummy 200 when the test dummy 200 impacts in the direction of the front windshield 400, and reduce the damage to the test dummy 200.

Specifically, the airbag 20 is inflated and deployed after receiving the gas generated by the gas generator 10, the deployment of the airbag 20 may be in a three-dimensional structure, and an end of the airbag 20 remote from the trunk 205 of the test dummy 200 may be partially brought into abutting contact with the front windshield 400 of the vehicle 1000. When the vehicle 1000 is subjected to a collision test, the test dummy 200 in the front passenger seat 300 is moved forward into contact with the surface of the air bag 20, and the air bag 20 is supported by the front windshield 400, thereby providing a protective support for the test dummy 200.

Referring to fig. 1-3, in certain embodiments, the test dummy 200 comprises a 5 percentile female dummy, and the airbag 20 is configured such that, in the inflated and deployed state of the airbag 20, the arc of the airbag 20 is oriented towards the head 201 of the 5 percentile female dummy, which is the same as the neck-neck arc of the head 201 and neck 203 of the 5 percentile female dummy when they impact the airbag 20.

In this way, the radian of the portion of the airbag 20 facing the head 201 of the 5 th percentile female dummy is the same as the head and neck radian of the 5 th percentile female dummy when the head and the neck collide with each other, so that the injury of the neck 203 of the passenger caused by backward extrusion of the head and the neck of the passenger after the airbag 20 is inflated and deployed can be avoided.

It should be noted that the test dummy 200 according to the embodiment of the present application may include a 5-percentile female dummy, and the 5-percentile female dummy may be a Hybrid III 5-percentile female dummy that can meet the standards of the collision safety regulations of FMVSS208\ u.s.ncap in the united states. A 5 th percentile female dummy may have both a belted and unbelted condition sitting still in the front passenger seat 300.

In the collision test of the vehicle 1000, the test dummy 200 may be positioned such that a 5 th percentile female dummy sits still on the front passenger seat 300 at the same height and can support the head 201 of the occupant when the airbag 20 is inflated and deployed to contact the occupant, preventing injury to the neck 203 of the occupant.

Specifically, the airbag 20 is configured such that in the inflated, deployed state of the airbag 20, the uppermost surface 23 of the airbag 20 can be a plane of the airbag 20 that is the greatest in linear distance from the lowermost surface 22. In the collision of the vehicle 1000, the airbag 20 is collided and deployed, the 5 th percentile female dummy moves to just contact with the fully inflated and deployed airbag 20, and the top head surface 204 of the 5 th percentile female dummy is at the same height as the highest surface 23 in the width direction of the airbag 20. It will be appreciated that the highest face 23 of the air bag 20 is located at the same height from the floor as the top face 204 of the 5 th percentile female dummy is located at from the floor, with reference to the floor of the vehicle 1000.

Referring to fig. 1-3, in certain embodiments, the airbag 20 is configured such that the airbag 20 is spaced from an a-pillar 800 of the vehicle 1000 when the airbag 20 is in an inflated, deployed state.

In this way, the airbag 20 is in the inflated and deployed state, and a gap is formed between the airbag 20 and the a-pillar 800 of the vehicle 1000, and the airbag 20 can be pressed to fill the gap when an occupant contacts the airbag 20, so that the occupant can be protected in the lateral direction.

Specifically, in the inflated and deployed state of the airbag 20, one end of the airbag 20 in the width direction of the vehicle 1000 may be close to the steering wheel and the other end may be close to the a-pillar 800, and an end surface of the airbag 20 close to the a-pillar 800 has an air gap distance from the a-pillar 800 of the vehicle 1000.
