Problems solved by technology

The airbag device directly inflates the airbag through the gas generator. The gas generator has high utilization efficiency, fewer parts and low cost, but it does not take into account the impact on the sun visor when the air bag is deployed, and the sun visor is damaged when the air bag is deployed. The risk of injury to the occupants due to the violent impact directly falling off

Embodiment 1

[0027] see figure 1 , the present invention is a ceiling safety airbag device, including a gas generator, a heat insulation sheet, a housing and an air bag, the gas generator 1-1 is placed inside the air bag 1-2, and the gas generator 1-1 is an air bag 2-2 The smooth deployment of 3 provides sufficient gas and energy, and the airbag 1-2 provides a carrier for the gas produced by the gas generator 1-1, and is deployed between the instrument panel and the occupant when the airbag is working, so as to provide protection for the occupant. A heat insulating sheet 1-3 is provided between the gas generator 1-1 and the housing 1-4, and the heat insulating sheet 1-3 guides the gas generated by the gas generator 1-1 to prevent the air bag 1-2 from being The high-temperature gas generated by the gas generator 1-1 is scalded, and the housing 1-4 provides an installation interface for the air bag 1-2, the gas generator 1-1 and the heat shield 1-3, and provides guide and support. The pres...

Embodiment 2

[0036] see Figure 7, in this example, the first-stage push-fold structure 6-2 is a symmetrical V-shaped fold structure, and the second-stage push-fold structure 6-3 is a finger-shaped fold structure. The supporting folding structure 6-4 is a folding structure, the occupant cushioning protection folding structure 6-5 is a rolling folding structure, and the internal pressure self-adjusting folding structure 6-6 is arranged in the occupant buffering protection folding structure 6-5.

[0037] When the airbag 2-3 is in operation, the vertically symmetrical V-shaped structure of the first-stage propulsion folding structure 6-2 pushes the support folding structure 6-4 and the occupant buffer protection folding structure 6-5 to unfold forward along the X direction of the vehicle body. Push forward the folding structure 6-3 Finger-type folding structure exhibits the ceiling 2-2 at the first time when the airbag 2-3 is deployed, and flips the ceiling 2-2 to provide display space for th...

Abstract

The invention relates to the technical field of automobile passive safety, in particular to a roof safety airbag device. The roof safety airbag device comprises a gas generator, a heat insulation sheet, a shell and an airbag; the airbag comprises a primary propelling folding structure, a secondary propelling folding structure and an airbag main body; the primary propelling folding structure is arranged between an inflating opening and the airbag main body; the secondary propelling folding structure is positioned at the tail end of the airbag main body; and the airbag main body comprises a supporting folding structure, a passenger buffering protection folding structure and an internal self-adjusting folding structure. Compared with the prior art, the roof safety airbag device has the advantages that the airbag main body is rapidly pushed out from a roof by using the primary propelling folding structure and the secondary propelling folding structure to solve the problem of impact of theroof safety airbag device on a visor, the roof and a peripheral environment piece; by using a two-wing symmetric folding structure, an airbag attitude self-adjusting folding structure and the internalpressure self-adjusting folding structure, the airbag main body is rapidly unfolded after being separated from the roof to provide rapid and effective comprehensive protection to passengers in an automobile.

Description

technical field [0001] The invention relates to the technical field of automobile passive safety, in particular to a ceiling safety air bag device. Background technique [0002] After more than 100 years of continuous innovation and development in the automobile industry, automobile designers are no longer satisfied with pure mechanical design, but pay more attention to innovative design with intelligence, high safety performance and comfort. On the premise of ensuring the safety of the occupants, in order to get rid of the constraints of the interior space on intelligent equipment and occupant comfort, a ceiling-type frontal airbag has appeared to replace the traditional frontal airbag installed in the instrument panel, so that the instrument panel The design is more concise and flexible, and part of the space on the dashboard is released, providing designers with more possibilities for innovative designs. [0003] Therefore, the innovative design of the roof-type front pr...
