Abstract

The present invention discloses a safety air bag device for a vehicle. The device comprises: a main chamber configured to employ air pressure to unfold facing the passenger of the vehicle when an inflator is exposed; a support chamber configured to joint with one side of the main chamber, wherein the support chamber is unfolded by employing the air of the main chamber; a movable venthole configured to be installed in the path of the main chamber being connected with the support chamber so as to open and close the path; and a controller configured to control the switching operation of the movable venthole.

Description

technical field [0001] The present invention relates to an air bag device for a vehicle, and more particularly, to a technology for an air bag device for a vehicle that utilizes a main tube at the time of a collision with a new frontal examination moving damage barrier. ) and a support tube connected to the main cavity more effectively protect the safety of occupants of the vehicle. Background technique [0002] Automakers have developed and sold a vehicle that satisfies a small repetitive crash test set by the Insurance Institute for Highway Safety (IIHS) in the United States to fit into an overseas sales network. [0003] IIHS's small repeat crash test is carried out under the conditions of vehicle speed: 64km / h, angle: 0° frontal, offset: 25%, and barrier: rigid column. Thereafter, vehicles need to meet a new frontal inspection moving damage barrier test for greater consideration of passenger safety. [0004] The new frontal inspection moving damage barrier test is anal...
