With the development of automobile modernization, particularly the advance of "intellectualization", an intelligent automobile with L4 and L5 level automatic driving in the future does not need to be operated by a driver, in this case, the driver does not need to hold a steering wheel by hands and step on a clutch pedal, a brake pedal and an accelerator pedal by feet, all passengers in the automobile do not need to be fixed in the front direction, and the seats of the passengers can freely rotate, so that the corresponding passengers in the automobile can have different riding directions along with the steering of the seats.
Disclosure of Invention
In order to solve the problems that in case of collision accidents, conventional steering wheel airbags, instrument panel airbags, seat side airbags, side air curtains and knee airbags arranged on vehicles at present lose the protection effect and the like, the invention provides a novel unfolding type safety airbag assembly which is matched with electric pre-tightening safety belts for use, wherein the airbag assembly is arranged on two sides of a seat back, and when a vehicle control system detects that collision cannot be avoided no matter how each seat in the vehicle faces, the electric pre-tightening safety belts tightly tie passengers on the seat, the airbags are ejected from two sides of the seat back to annularly surround the passengers, so that secondary collision between the passengers and vehicle interior decorations is avoided, and the safety of the passengers can be protected under the automatic driving scenes of L4 and L5 levels in the future.
The invention is realized by the following technical scheme:
a novel expansion type safety air bag assembly comprises a seat backrest 4 and a safety air bag assembly; the safety airbag assembly comprises a wiring harness assembly 3, a first airbag 1 and a second airbag 2 which are connected by the wiring harness assembly 3; the first air bag 1 and the second air bag 2 are respectively arranged on a side sheet metal framework of the seat backrest 4, the wiring harness assembly 3 is clamped in a rear foam groove of the seat backrest 4, and a seat skin covers the wiring harness assembly; the airbag joint of the wire harness assembly 3 is connected with a vehicle body wire harness.
Further, the first airbag 1 and the second airbag 2 are composed of a mounting bracket 5, a gas generator 6, a gas bag 7 and cover cloth 8, the gas generator 6 is connected with the gas bag 7 and then mounted on the mounting bracket 5, and the cover cloth 8 wraps the outside of the gas bag 7.
Further, both the first airbag 1 and the second airbag 2 may be inflated to an inflated position to form a first airbag 10 and a second airbag 11, respectively.
Further, the first bag 10 and the second bag 11 each have a curved portion, and the first bag 10 and the second bag 11 extend along the side surface of the seat back 4 to the front surface of the seat back 4 to form an annular enclosure for the occupant 9.
Compared with the prior art, the invention has the following advantages:
1. the airbag arrangement mode in the prior art is that the airbag is fixed at a specific position, is respectively detonated aiming at a specific collision mode, and can play a necessary protection role when the seat is required to be moved forwards. The safety airbag assembly is suitable for various use orientations of seats in the vehicle for intelligent automatic driving vehicles, can effectively protect the safety of passengers, and has great convenience.
2. The safety airbag assembly saves other airbag modules such as a steering wheel airbag, an instrument panel airbag, a seat side airbag, a side curtain airbag, a knee airbag and the like in a vehicle, and greatly reduces the cost.
3. The safety airbag assembly has a simple structure, the airbag combination mode and the arrangement mode are simple and convenient, and the unfolding mode is annular surrounding type, so that secondary collision between passengers and vehicle interior trim is avoided, and the safety of drivers and passengers is protected.
Drawings
FIG. 1 is a schematic view of the construction of an airbag assembly of the present invention;
FIG. 2 is an exploded view of the airbag assembly of the present invention;
FIG. 3 is a schematic illustration of the deployment of the airbag assembly of the present invention;
in the figure: a first airbag 1, a second airbag 2, a wire harness assembly 3, a seat back 4, a mounting bracket 5, a gas generator 6, an airbag 7, a cover fabric 8, an occupant 9, a first airbag 10, a second airbag 11.
Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Example 1
As shown in fig. 1, a new deployment airbag assembly includes a seat back 4 and an airbag assembly; the safety airbag assembly comprises a wiring harness assembly 3, a first airbag 1 and a second airbag 2 which are connected by the wiring harness assembly 3; the first air bag 1 and the second air bag 2 are respectively arranged on a side sheet metal framework of the seat backrest 4, the wiring harness assembly 3 is clamped in a rear foam groove of the seat backrest 4, and a seat skin covers the wiring harness assembly; the airbag joint of the wire harness assembly 3 is connected with a vehicle body wire harness.
As shown in fig. 2, the first airbag 1 and the second airbag 2 are both composed of a mounting bracket 5, a gas generator 6, an airbag 7 and a cover cloth 8, the gas generator 6 is connected with the airbag 7 and then mounted on the mounting bracket 5, and the cover cloth 8 is wrapped outside the airbag 7.
Both the first and second airbags 1, 2 are inflatable to an inflated position to form first and second airbags 10, 11, respectively.
The first bag 10 and the second bag 11 each have a curved portion, and the first bag 10 and the second bag 11 extend along the side surface of the seat back 4 to the front surface of the seat back 4 to form an annular enclosure for the occupant 9.
The assembly process of the novel deployment airbag assembly of the present invention is as follows:
first, two airbags are assembled, the gas generator 6 and the airbag 7 are assembled, then the gas generator 6 is placed on the mounting bracket 5, the airbag 7 is folded according to the requirements of the drawing, and a cover cloth 8 is wrapped outside the airbag.
Then, the first air bag 1 and the second air bag 2 are combined into an air bag assembly by using the wire harness assembly 3, then the first air bag 1 and the second air bag 2 are respectively installed on a sheet metal framework on the side surface of the seat backrest 4, the wire harness assembly 3 is clamped into a foam groove behind the seat backrest, and a seat skin is covered;
finally, the air bag connector of the wiring harness 3 is connected to the vehicle body wiring harness when the seat assembly is assembled in the workshop.
The working principle of the novel expansion type safety air bag assembly is as follows:
when a vehicle control system detects that collision cannot be avoided, the electric pre-tightening safety belt rewinds the woven belt, a gap between the safety belt woven belt and a passenger is eliminated, the air bag control unit senses the strength of an actual collision signal, if the collision is severe, an ignition signal is sent out, the pre-tightening safety belt plays a role, the passenger 9 is tightly bound on the seat, the novel safety air bag assembly starts to work, air bags on two sides are unfolded, an arc enclosure formed by a first air bag 10 and a second air bag 11 is formed, the passenger is enclosed in the middle, as shown in an effect schematic diagram after being unfolded in fig. 3, the passenger is prevented from having secondary collision with surrounding environment parts, and the effect of protecting the passenger is achieved. Because under the effect of pretension safety belt, the passenger can hug closely the back of the seat, so can ensure that can not strike the passenger when new form gasbag expandes, because new form gasbag arranges in back of the seat both sides, consequently no matter how the orientation of passenger, the gasbag all can play the guard action, has avoided the limitation of arranging.
