Abstract

The invention discloses a safety air bag installed on the rear side of an automobile seat, and belongs to the field of vehicle engineering, the safety air bag comprises an air bag release device installed on a backrest of the automobile seat, and further comprises a sliding support, a transmission mechanism and a driving mechanism, the sliding support is slidably connected with a track of the automobile seat, and the top of the sliding support is connected with the air bag release device; the driving mechanism comprises a rack arranged in the track in the same direction and a support gear installed at the lower end of the sliding support, the support gear is meshed with the rack, an air bag releasing device is installed at the upper end of the sliding support, the transmission mechanism is installed on a side support assembly of the sliding support, and the support gear drives the adjusting mechanism through the transmission mechanism. The adjusting mechanism is used for adjusting the adjustable valve to change the inflation volume proportion of the forward air bag and the lateral air bag. The ratio of the air output of the forward air bag to the air output of the lateral air bag can be changed no matter the seat backrest rotates or the seat body slides front and back, and passengers in the rear row are protected from being hurt by impact force generated when the air bags are opened.

Description

technical field [0001] The invention relates to the field of vehicles, and in particular relates to a safety airbag installed on the rear side of a car seat. Background technique [0002] At present, in the field of automobile safety, considering the safety of passengers in various positions, there are more and more airbags installed, and there are many cases where rear passengers need airbag protection. This is a common way to set them in the front row in front The airbag is installed on the back of the car seat. However, this setting method needs to consider the position change of the airbag when the backrest of the car seat moves, such as the rotation of the backrest and the sliding of the seat back and forth. The distance between the rear passenger parts changes. If the distance is too close, when the airbag is deployed at high speed, it may cause a huge impact to the passenger because it is too close to the passenger. In serious cases, the rear passenger may be injured ...
