Abstract

The present invention relates to an airbag including: an inflator; and an airbag cushion which is deployed by gas flowing into the airbag cushion from the inflator, in which the airbag cushion has a burst portion at least a part of which is torn from the airbag cushion so as to form a burst hole through which gas flowing into the airbag cushion is discharged to the outside.

Description

technical field [0001] The present invention relates to an airbag, and more particularly to a structure for absorbing impact energy by adjusting the internal pressure of the airbag provided in a vehicle. Background technique [0002] In general, vehicles have various safety devices for protecting passengers in unexpected situations that may occur at any time, and typical ones are interior airbags for protecting passengers and exterior airbags for protecting victims. [0003] However, the airbag deploys in an instant and cannot sufficiently absorb the impact energy, so passengers or victims may be seriously injured. [0004] Therefore, in order to absorb the impact energy, the existing airbag adopts the concept of active exhaust, in which, in terms of the structure of the airbag for the passenger seat, in order to meet the commerciality / legal performance, a side panel converges like a low-risk scheduling exhaust structure (LOW RISK DEPLOYMENT VENT; LRD VENT), general exhaust...
