Problems solved by technology

However, due to the structure of the curved portion such as image 3 As shown, high temperature impurities will fall on the top of the gas generator, such as image 3 As shown by the middle arrow, due to the strong impact force of the gas, a small number of high-temperature impurities are prone to rebound, even if they act on the top of the airbag buffer, corrosion holes will still occur
With the existing structure, it cannot completely prevent the high-temperature impurity from corroding the airbag buffer

Embodiment 1

[0022] Such as figure 1 and figure 2 The shown airbag suitable for following cars includes an airbag cushion 7, a gas generator 1 and a retainer between the airbag cushion 7 and the gas generator 1, and the retainer includes a barrier sill 2 and a downwardly bent The curved part 3, the said blocking sill 2 is quadrilateral and the two opposite corners of the blocking sill 2 are respectively connected with the first blocking piece 5 and the second blocking piece 6, the first blocking piece 5 and the second blocking piece High-temperature impurity adsorption layers 4 are provided on both sides of the sheet 6, and the curved portion 3 is larger than a quarter of a circular arc and smaller than a half of a circular arc. The high-temperature impurity adsorption layer can be realized in various ways, for example, using a wet adhesive layer.

Embodiment 2

[0024] Such as figure 1 and figure 2 The airbag shown is suitable for following cars. This embodiment is optimized on the basis of the above embodiments, that is, the lengths of the first blocking piece 5 and the second blocking piece 6 are equal.

Embodiment 3

[0026] Such as figure 1 and figure 2 The airbag shown is suitable for following cars. In order to completely block the rebound channel of high-temperature impurities, this embodiment is optimized on the basis of the above-mentioned embodiments, that is, the first blocking piece 5 and the second blocking piece The height of sheet 6 is not lower than the height of blocking sill 2.

Abstract

The invention discloses a safety airbag suitable for a car following, which comprises an airbag cushion, a gas generator and a retainer located between the airbag cushion and the gas generator, and the retainer includes a blocking sill and a downwardly curved bend part, the blocking sill is quadrangular and the two opposite corners of the blocking sill are respectively connected with a first blocking sheet and a second blocking sheet, and both sides of the first blocking sheet and the second blocking sheet are provided with high temperature In the impurity adsorption layer, the curved portion is larger than a quarter arc and smaller than a half arc, which not only has a stable structure, but also can completely block the corrosion of the airbag buffer by high-temperature impurities.

Description

technical field [0001] The invention relates to the field of safety airbag equipment, in particular to a safety airbag suitable for cars following cars. Background technique [0002] Since the car was born at the end of last century, it has gone through more than 100 years of ups and downs. Car-following is the driving state in which the vehicle behind follows the vehicle in front when vehicles line up on a single lane, that is, the vehicle in front and the vehicle in the rear achieve information communication. Automated driving is realized by following the car driving scheme. The airbag is to reduce the damage to the driver and passengers caused by the huge inertia when the car has a frontal collision, so the airbag is very important for the following car. [0003] The airbag generally includes an outer cover, a gas generator, and an airbag cushion. The airbag cushion is opened by the deployment gas supplied by the gas generator. The gas generator processes the deploymen...
