Abstract

The present invention provides a safety airbag, which comprises an inflator and a safety airbag cushion. In this way, the air is driven to expand inside the inflator. The safety airbag cushion is provided with a rupture part. Therefore, the pressure inside the safety airbag cushion is increased, while the peripheral rupture at the safety airbag cushion is torn open. As a result, rupture holes used for discharging air inside the safety airbag cushion to the outside are formed.

Description

Technical field [0001] The present invention relates to an airbag, and more specifically, to an airbag having an impact-absorbing structure that adjusts the internal pressure of an airbag cushion installed in a vehicle. Background technique [0002] Generally speaking, to prepare for emergencies that may not happen at a certain moment, the vehicle has various safety devices to protect the occupants, as a representative of which built-in airbags are installed to protect the occupants, and the External airbags. [0003] However, this kind of airbag cannot fully absorb the impact energy due to the instantaneous deployment, which will cause greater injury to the occupant or the person being collided. [0004] Therefore, in order to absorb the impact, the concept of active vents is applied to the existing airbags. In order to meet the commercial / regulatory performance, the same-seat airbags have the same LRD vents (LOW RISK DEPLOYMENT VENT, low risk deployment vents). ), The general ven...
