Technical Field

[0001] The utility model relates to the technical field of rear air bag detection, in particular to a rear air bag air tightness detection device. Background Art

[0002] The rear airbags are installed in three directions: the front (driver and co-driver seats), the sides (front and rear seats) and the roof. The function of the airbags is to reduce the injury level of the occupants when the vehicle is involved in a collision, to prevent the occupants from being thrown out of their seats in dangerous situations such as secondary collisions or vehicle rollovers.

[0003] However, in the prior art, in order to ensure the quality and normal use of the rear air bag, it is necessary to perform an air tightness test on the rear air bag. The common air tightness detection device is not convenient to connect with the rear air bag, and only a single pressure gauge is provided. The detection result is prone to errors. For this reason, we propose a rear air bag air tightness detection device. Utility Model Content
