In the description of the present invention, it is noted that the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two elements may be directly connected or indirectly connected through an intermediate medium, or may be communicated with each other inside the two elements, or may be wirelessly connected or wired connected. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Since the existing hydrogen powered automobile has started to use photochromic glass as a front windshield, the use of a sun visor is cancelled, and light shielding is satisfied by the front windshield having a specific transmittance. Thus, a new ceiling airbag can be redesigned in place of the visor instead of the existing conventional airbag device.

However, the existing ceiling airbag lacks a design that fully considers the direction of the airbag during deployment, and the structure is not improved, so that the positions of main passengers, auxiliary passengers and rear passengers cannot share the same ceiling airbag, and for the same hydrogen energy automobile, a plurality of ceiling airbags are needed to meet the passive safety requirements of different riding positions, and the mold cost is increased.

In order to solve the above problems, as shown in fig. 1-6, an embodiment of the present invention provides a ceiling airbag for use in a hydrogen-powered automobile without a sun visor, comprising a gas generator 3, a gas bag 6 and an airbag housing 4, wherein the gas generator 3 is internally disposed in the gas bag 6, the gas bag 6 is mounted in the airbag housing 4, the airbag housing 4 is mounted in a ceiling 5, the airbag mounting bracket 2 is connected to the outer circumference of one end of the airbag housing 4 close to the gas generator 3, the door mounting bracket 9 is connected to the outer circumference of the other end,

the airbag mounting support 2 comprises a first mounting frame 21, an intermediate connecting frame 22 and a second mounting frame 23 which are sequentially connected, one side, far away from the gas generator 3, of the first mounting frame 21 and the second mounting frame 23 are respectively connected with the car body top cover beam 1, and two sides of the door cover mounting support 9 are respectively connected with the airbag door covers 7 so as to enable the airbag door covers 7 to be covered on openings of the airbag shell 4 and the ceiling 5.

As shown in fig. 1 in particular, the roof airbag is installed in the roof above the occupant and includes a gas generator 3, a bag 6, and an airbag case 4. When the air bag works, the high-temperature and high-pressure gas generated by the gas generator 3 is guided by the air bag shell 4 to inflate the air bag 6, so that the air bag is smoothly unfolded to achieve the function of protecting passengers. This ceiling air bag directly inflates air pocket 6 through gas generator 3, and gas generator 3's utilization efficiency is higher, because there is not the hindrance of sunshading board when the gasbag expandes, can expand in main and copilot position smoothly to one set of ceiling air bag can be shared, carry out safety protection to the passenger of main and copilot.

Through the structure of design ceiling formula air bag, at air bag casing, gasbag installing support, gasbag door closure isostructure improvement, solved main, copilot position sharing air bag's problem, provide sufficient expansion space for the gasbag under the prerequisite of guaranteeing the ceiling integrality, reduce the development expense of mould because of sharing the gasbag simultaneously. Because the upward protruding part of the lower frame protection area of the air bag 6 is provided with the vent hole, after the air bag 6 of the safety air bag is contacted with a driver and a passenger of an automobile, the air bag 6 of the safety air bag has an energy absorption function, and the vent hole adjusts the internal pressure, thereby achieving a reasonable protection effect.

When the automobile collides within the range of 30 degrees from the left to the right of the front, the air bag 6 can protect the head of the front-row driver or the rear-row passenger in the front, and prevent the head of the passenger from deviating out of the air bag, thereby realizing the all-round protection of the head. The inner drawstring is arranged in the protection area of the air bag 6, so that the thickness and the shape of the protection area of the air bag 6 can be controlled more conveniently, and reasonable protection is realized.

The utility model discloses can be widely applied to front row owner driver, front row copilot passenger, the front protection and the side protection of back row passenger.

Specifically, the airbag door 7 includes a snap mount 71 disposed on the outer periphery, and a limit snap 711 is provided at the end of the snap mount 71, and the limit snap 711 is snap-connected to the ceiling 5.
