Description

Technical Field

[0001] The utility model relates to the technical field of automobile airbags, in particular to a passenger airbag. Background Art

[0002] Airbags, also known as "auxiliary occupant protection systems" or "airbag systems", are an important passive safety feature in modern compact cars. Airbags consist of three parts: airbags, sensors, and inflation systems, and are used to protect people inside the car.

[0003] In the passenger seat of a car, the passenger airbag is used to protect the safety of the passenger. During the riding process, the passenger's sitting posture may not be particularly facing the airbag. At this time, when an accident occurs, the airbag cannot effectively protect the passenger. The passenger may be ejected by the airbag, which is not conducive to the safety of the passenger. Utility Model Content

[0004] The purpose of the present invention is to provide a passenger airbag to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a co-pilot airbag, comprising a shell, which is fixedly installed inside the co-pilot platform of a car, and also comprising an airbag, the interior of the airbag is connected to the gas generator in the shell, the airbag is fixedly sleeved on the inner circle position of the shell, the airbag comprises a central circular airbag and side airbags, the side airbags are connected to the central circular airbag, and the side airbags are arranged on both sides of the central circular airbag.

[0006] As a further preferred embodiment of the present technical solution, the side airbags are arranged at an angle.

[0007] As a further preferred embodiment of the present technical solution, the central surface of the central circular airbag is concave.

[0008] As a further preferred embodiment of the present technical solution, the gas generated by the gas generator in the shell first fills the side airbags and then fills the central circular airbag.

[0009] As a further preferred embodiment of the present technical solution, the side airbags in the housing are rolled up above the central circular airbag when in an unactuated state.

[0010] The utility model provides a passenger airbag, which has the following beneficial effects:

[0011] (1) The utility model uses a chemical inflation component inside the shell to transport the gas generated by the heating, ignition and explosion of the resistance wire into the interior of the airbag, and squeezes and protects both sides of the front passenger's head through the side airbag, gathering the front passenger's head toward the middle of the airbag, preventing the front passenger from sitting in a tilted position and failing to provide effective protection for the front passenger.

[0012] (2) The utility model first fills the side airbags with air and expands them to squeeze and protect the two sides of the front passenger's head, and to control the front passenger's head to be pushed toward the middle. Then, the remaining gas will all rush into the middle circular airbag to fill the middle circular airbag and protect the entire front passenger's head. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] The utility model provides a technical solution: Figures 1 to 3As shown, in this embodiment, a passenger airbag includes a shell 1, and a chemical inflation component is installed inside the shell 1. When the vehicle collides, the chemical inflation component inside the shell 1 will generate gas under the heating, ignition and explosion of the resistance wire, which is used to transport the gas to the inside of the airbag 2. The shell 1 is fixedly installed inside the passenger seat of the car, and also includes an airbag 2. The interior of the airbag 2 is connected to the gas generator in the shell 1, and the airbag 2 is fixedly sleeved on the inner circle position of the shell 1. The airbag 2 includes a central circular airbag 21 and side airbags 22. The side airbags 22 are connected to the central circular airbag 21, and the side airbags 22 are arranged on both sides of the central circular airbag 21. The gas generator in the shell 1 generates The gas first fills the side airbags 22 and then fills the central circular airbag 21. When the vehicle collides, the chemical inflation component inside the shell 1 will transport the gas generated by the heating and ignition of the resistance wire into the airbag 2, and break the co-pilot's table, causing the airbag 2 to leak out. Part of the gas will pass into the central circular airbag 21. Since the side airbags 22 are smaller in size, the side airbags 22 will be filled with gas and expanded first to squeeze and protect both sides of the co-pilot's head, and to control the co-pilot's head to be pushed toward the middle. Then, the remaining gas will all rush into the central circular airbag 21 to fill the central circular airbag 21 and protect the co-pilot's entire head.

[0019] like Figures 1 to 3 As shown, the side airbag 22 is tilted after being inflated.

[0020] It is used to prevent the front passenger's head from being excessively offset from the middle of the airbag and unable to provide protection.

[0021] like Figures 1 to 3 As shown, the central circular airbag 21 has a concave surface at its central portion after being inflated.

[0022] It is used to restrict the front passenger's head and prevent the outer ring of the inflated central circular airbag 21 from squeezing the front passenger's head away from the airbag.

[0023] like Figures 1 to 3 As shown, the side airbag 22 in the shell 1 is rolled up above the central circular airbag 21 when it is in an untriggered state. When the airbag 2 is compressed and stored in the middle of the shell 1, the central circular airbag 21 is folded into four sides, and the four folded sides of the central circular airbag 21 are stacked in sequence. At the same time, the two sides of the central circular airbag 21 with the side airbag 22 installed are set at the top.

[0024] By doing so, the side airbag 22 can be inflated first.

[0025] The utility model provides a passenger airbag, the specific working principle of which is as follows:

[0026] When the device is in use, when the vehicle collides, the chemical inflation component inside the shell 1 will generate gas under the heating, ignition and explosion of the resistance wire, which is used to transport the gas to the inside of the airbag 2 and break the passenger seat table, causing the airbag 2 to leak out. A part of the gas will pass into the middle circular airbag 21. Since the volume of the side airbag 22 is smaller, the side airbag 22 will be filled with gas and inflated first. Then, the remaining gas will all rush into the inside of the middle circular airbag 21 to fill the middle circular airbag 21.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
