Abstract
A passenger airbag module includes a housing, an inflator generating gas pressure according to a control signal of an electronic control unit, and an airbag cushion folded in the housing such that the airbag cushion is expanded in the form of a dual chamber. The airbag cushion is provided therein with a tether having a rectangular shape corresponding to a sectional shape of the airbag cushion. The tether is installed in the transverse direction to divide the airbag cushion into an upper chamber and a lower chamber. Transfer holes are formed at edges of the tether. In the passenger airbag module, the upper chamber is primarily expanded by concentrating gas flow into the upper chamber to instantly deploy the airbag cushion in the proper position, thereby safely protecting the occupants.
