Abstract

In an air bag unit, which comprises a retainer (6), an inflator (7, 15, 20, or 22) blowing gas from L blowing holes (7a) at the collision of the vehicle, and an air bag (8) inflated and developed by the gas thus blown out, said inflator (7, 15, 20, or 22) is provided with a mounting member (7d), which comprises an opposed wall (7b) placed face-to-face to the blowing holes (7a) and a mount (7c) with said retainer (6), and the mounting member (7d) and the retainer (6) are connected by connection members (9, 16, 18, 21, or 24) with the mounting end (8a) of said air bag (8) squeezed between said mounting member (7d) and said retainer (6). Because the inflator (7, 15, 20, or 22) itself is provided with an opposed wall (7b) placed face-to-face to the blowing holes (7a) and the mount (7c) with the retainer (6), there is no need to furnish special mounting member such as ring member used in the conventional type air bag unit. This makes it possible to reduce the number of component parts and to provide the air bag unit in compact and lightweight design as no special mounting member is required.
