Abstract
The present invention relates to an airbag including an inflating part having gas inflatability, a non-inflating part supporting the inflating part, a combined part constituting a boundary between the inflating part and the non-inflating part, and an ultrasonic fusion bonded part located between the combined part and the end part of an inflator from which a gas at a high pressure spurts when a car crashes, and a preparation method thereof.
Claims13
An airbag, including
- an inflating part having gas inflatability, a non-inflating part supporting the inflating part, a combined part constituting a boundary between the inflating part and the non-inflating part, and an ultrasonic fusion bonded part located between the combined part and the end part of an inflator from which a gas at a high pressure spurts when a car crashes.
A method of preparing an airbag, including steps of:
- preparing a double-layered fabric including an inflating part having gas inflatability, a non-inflating part supporting the inflating part, and a combined part constituting a boundary between the inflating part and the non-inflating part;
- and
- forming an ultrasonic fusion bonded part at the double-layered fabric between the combined part and the end part of an inflator from which a gas at a high pressure spurts when a car crashes.
