Abstract

In accordance with a knee airbag module for a vehicle according to the present invention, an airbag cushion is folded in half in the front and rear directions, folded in the left and right directions, and is then contained. Thus, when the airbag cushion is supplied with a high pressure gas, it is expanded and unfolded in the left and right directions and is then expanded and unfolded in the front and rear directions. Therefore, the airbag cushion is not unfolded between the knees of a passenger, but is unfolded at the front of the knees of the passenger. Accordingly, the unfolding performance and stability can be improved.

Description

technical field [0001] Generally the present invention relates to an airbag assembly for a vehicle. More particularly, the present invention relates to a knee airbag module for a vehicle in which an airbag cushion is folded in half in the front-rear direction, folded in the left-right direction, and then housed so that it can be mounted on the airbag. The cushion cushion is deployed more smoothly in the left and right directions when it is initially deployed, thereby improving the deployment performance and stability of the airbag cushion. Background technique [0002] Generally, the airbag system includes a driver airbag installed to protect the driver, a passenger airbag installed on the front seat to protect the passenger, and a side airbag configured to inflate from the door to protect the sides of the driver, passenger, etc. , A knee airbag installed to protect the driver's or passenger's knees. [0003] figure 1 It is a side view showing a conventional knee airbag o...
