Abstract
A curtain airbag for a vehicle is configured to prevent a driver's neck from being broken by preventing a driver's head from being excessively rotated upon a crash of the vehicle in a state in which the driver's head contacts an airbag tube. The curtain airbag is also configured to prevent the driver's head from slipping through or between the curtain airbag and a driver airbag by removing a gap between the curtain airbag and the driver airbag when the driver's head moves forward during a crash of the vehicle.
Claims16
A curtain airbag for a vehicle, the curtain airbag comprising:
- an airbag tube configured to include a main chamber that is inflated by being supplied with a gas from an inflator and to absorb an impact when a driver's head moves laterally and to include an auxiliary chamber that is bendably connected to the main chamber and supplied with the gas from the main chamber to be inflated later than the main chamber;
- and
- a guide panel configured to be fixedly installed on a vehicle body and connected to the airbag tube to support the main chamber and the auxiliary chamber so that the main chamber and the auxiliary chamber are inflated inwardly when the airbag tube is inflated,
- wherein when the driver's head moves laterally upon a crash of the vehicle to collide with the main chamber, as the gas within the main chamber moves to the auxiliary chamber, the auxiliary chamber is inflated and is bent inwardly by the guide panel to prevent the gas within the auxiliary chamber from reflowing to the main chamber.
