Description

Technical Field

[0001] The utility model relates to the technical field of automobile air curtain testing, in particular to a side air curtain detonation testing device. Background Art

[0002] The side curtain airbags include bags, gas generators, brackets and belts, which are generally installed on the left and right sides of the vehicle roof. When a side collision or rollover occurs during driving, the gas generator receives an ignition command to ignite the gas generator, which is usually based on chemicals such as sodium nitride (NaN3). These substances produce a large amount of nitrogen (N2) during the combustion process, which is quickly filled into the airbag, causing it to expand and deploy in a very short time, forming a buffer area to reduce the damage to passengers in side collisions or rollovers.

[0003] As one of the important accessories for automobile passive safety, side curtain airbags are usually tested during the vehicle's safety performance test to collect and verify parameters such as the bag filling time, coverage area, and pressure inside the bag during the side curtain airbag explosion process.

[0004] For the detonation test, the industry currently mainly uses contoured fixtures or body benches for detonation test verification, but it is generally difficult to adjust the body and surrounding parts after they are locked. Whenever the test parameters need to be adjusted, the test fixture needs to be modified. A new project may require the production or modification of one or more sets of test fixtures, which takes a lot of time and cost. Utility Model Content
