摘要： Provided is a knee airbag capable of adjusting the height and width of the airbag upon deployment thereof and deploying the airbag along a lower crash panel. The knee airbag is installed at a lower crash panel and has an inflator installed at a predetermined position thereof, wherein the knee airbag has at least one wrinkle part folded in a longitudinal direction of side surfaces thereof. Since an upper part of the knee airbag is expanded more than a lower part thereof, it is possible to more safely protect passenger's knees. In addition, since the knee airbag is expanded upward and downward, it is also possible to protect passenger's ankles and readily adjust the height and width of the knee airbag. Further, the knee airbag is expanded to correspond to an appearance of a lower crash, thereby more safely protecting the passenger.
