Blast channel housing in motor vehicle for forming blast channel to unfold gas bag, has blast channel wall with predetermined separation line, along which blast channel wall acts on load by partial absorption of introduced energy

摘要

The blast channel housing (2) has a blast channel wall (20) with a predetermined separation line (40), along which the blast channel wall acts on a load (42) by partial absorption of introduced energy. The blast channel wall acts on the load in a direction opposite to a blast direction (12) of a gas bag. The predetermined separation line has a shape deviating from a straight line, particularly a partial periodically repeating shape. The predetermined separation line is designed such that the wall portions of the blast channel wall are arranged opposite to each other. An independent claim is provided for a motor vehicle with an air bag device comprised of an inflatable airbag and a gas generator for inflating the gas bag.
