Description

Automobile front row safety airbag

Technical Field

The utility model relates to the field of automobiles, especially a car front-seat air bag.

Background

With the gradual and deep research on automobile safety, more and more attention is paid to the research work of the off-position passenger report. The off-position passengers are not located in the normal riding area, so that the restraint system cannot normally act, and the passengers are more easily injured when a traffic accident happens. In view of the fact that each FMVSS 208 regulation on occupant crash protection has increased the low risk deployment tests of airbags to enhance protection of out-of-position occupants for the years, the emergence of these terms has greatly facilitated research into out-of-position occupant protection.

In order to protect a passenger seated in a vehicle during a collision accident, vehicles are generally provided with various safety devices, and particularly, the vehicle is provided with an airbag module inside an instrument panel in front of a passenger seat in order to protect a seated passenger. The traditional safety airbag has great limitation on the appearance, the impact force is very large when the traditional safety airbag is unfolded, the impact force in the middle of the airbag is generally the largest, when a passenger sits abnormally, for example, when the passenger is close to an instrument desk, the safety airbag in a passenger seat is easily unfolded and often suffers secondary injury, so that the safety airbag in the front row of an automobile is urgently needed, and the secondary injury of the passenger is reduced.

Wherein:

fig. 1 is a plan view of a front airbag for an automobile.

The figures are labeled as: the air bag comprises a generator 100, an inner bag 200, an outer air bag 300, a first surface cloth 301, a second surface cloth 302, a third surface cloth 303, a second pull belt 304, a first vent hole 201, a second vent hole 305 and a first pull belt 400.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying the present invention are described in detail below with reference to the accompanying drawings.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Referring to fig. 1, the embodiment provides a front airbag for a vehicle, which includes a generator 100 disposed in an instrument panel of the vehicle; an inner bag 200 connected to the generator 100 and facing an occupant when deployed; an outer airbag 300 disposed outside the inner bag 200 and surrounding an outer circumference of the inner bag 200; the number of the first drawstrings 400 is at least two, one end of each first drawstring 400 is connected with the outer side of the inner bag 200, the other end of each first drawstring is connected with the outer side airbag 300, and the outer side airbag 300 is restrained to enable one side, opposite to an occupant, of the first drawstring to form an inwards concave space.

In the case of a frontal collision of the vehicle, the gas generator is controlled to ignite after the ECU in the vehicle determines that the collision may jeopardize the safety of the passenger, and the generator 100 may be installed in a dashboard facing the passenger or may be installed in a steering wheel of the driver's seat.

Preferably, the inner bag 200 is connected to the inflation port of the generator 100, and the inner bag 200 is in communication with the outer airbag 300. The outer bag 300 is disposed outside the inner bag 200, surrounds the outer periphery of the inner bag 200, and is sewn to the inner bag 200. Consequently after the ignition, inner bag 200 expands rapidly, and then convey gas to outside gasbag 300, makes outside gasbag 300 expand, and outside gasbag 300 expandes along front windshield at this inflation in-process, and expandes back outside gasbag 300 and can form the indent space for the passenger one side, can not be with traditional air bag in the same gasbag middle part salient very strong impact force that has that to say when expandeing, and the utility model discloses in inside sunken under the effect of stretching strap, if when the improper position of sitting of passenger, for example too be close to the panel board, perhaps the head is askew to both sides again, traditional gasbag can give passenger's huge impact force, causes secondary damage under the improper position of sitting of passenger more easily, and my utility model, outside gasbag 300 periphery can be outstanding to the passenger when the gasbag expandes, and the middle part can form the indent space, and the passenger is located the indent space this moment, has reduced passenger's secondary damage.

Preferably, the inner bag 200 is deployed with the surface facing the occupant and is adapted to protect the head of the occupant. The outer bag 300 can protect the body part of the occupant.

Preferably, the deployed surface of the inner bag 200 is relatively protruded than the concave surface of the outer bag 300 facing the occupant, or is depressed for protecting the head of the occupant.

Further, the outer airbag 300 is a bag body formed by sewing a first cover cloth 301, a second cover cloth 302, and a third cover cloth 303.

It should be noted that, the first cover cloth 301, the second cover cloth 302, and the third cover cloth 303 are sewn around the side of the inner bag 200 to ensure that the outer bag 300 is communicated with the inner bag 200, so that the gas first enters the inner bag 200 and then passes through the inner bag 200 to the outer bag 300.

Preferably, one of two drawstrings is first drawstring 400 one end inner bag 200 and is connected, and the other end is connected with first table cloth 301, and another first drawstring 400 one end is connected with inner bag 200, and the other end is connected with second table cloth 302, first table cloth 301 and second table cloth 302 form the indent space under the pulling force effect of first drawstring 400.

Further, a second pull tape 304 is disposed between the first cover cloth 301 and the second cover cloth 302.

Further, the second pull strap 304 is a flexible, stretchable strap.

It should be noted that the second drawstring further acts as a limit for the outer side airbag 300 on both sides after the airbag is opened, and can protect the head for cushioning.

Further, first vent holes 201 are formed at both sides of the inner bag 200.

Further, second vent holes 305 are formed at both sides of the outer bag 300.

The first vent hole 201 and the second vent hole 305 function to discharge the gas in the inner bag 200 and the outer bag 300.

To sum up, the utility model discloses the gasbag is installed in copilot instrument board position, makes outside gasbag 300 keep the shape that needs through second stretching strap 400 to protect copilot passenger's head and chest. When collision happens, the inner bag 200 protects the head from secondary injury, and the head is kept at a certain position after the outer air bag 300 is unfolded, so that the head and the chest are prevented from moving forwards or rotating, and the head and the chest of a passenger are protected from secondary injury.

It should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
