LOW RISK DEPLOYMENT PASSENGER AIRBAG SYSTEM USING SLIM TYPE PASSENGER AIRBAG MODULE
First Claim
1. A low risk deployment passenger airbag system having passenger airbag modules respectively mounted to an upper surface and a front surface of an instrument panel, wherein at least one of the passenger airbag modules comprises a slim type passenger airbag module, comprising:
- a box-shaped airbag housing, having an opening in a front end thereof, and a flange provided around the opening of the box-shaped airbag housing;
a disk type inflator, an upper end of which is inserted into the airbag housing through a circular insert hole formed through a bottom of the airbag housing, which is perpendicular to the opening;
a cushion stored in the airbag housing in a folded state such that the cushion is deployed towards a passenger seat through the opening by deployment gas discharged from the disk type inflator; and
a retainer fastening both an inlet part of the cushion and a ring-shaped flange, provided around a circumferential outer surface of the disk type inflator, to the bottom of the airbag housing a locking bolt, the retainer having a circular through hole, through which the upper end of the disk type inflator passes.

Abstract
Disclosed herein is a low risk deployment passenger airbag system using a slim type passenger airbag module which is minimized in height and/or length, such that a top airbag and a mid airbag can be installed in a limited space defined by an instrument panel. In the slim type passenger airbag module used in the low risk deployment passenger airbag system, a disk type inflator is used, unlike the conventional art using a cylindrical inflator, an upper end of the disk inflator is disposed in an airbag housing, and a retainer for supporting the cushion is brought into close contact with the bottom (or the rear surface) of the airbag housing in which the disk type inflator is provided, thus minimizing the height and/or length of the passenger airbag module. Thereby, the slim type passenger airbag module is suitable for the low risk deployment passenger airbag system. Furthermore, in the low risk deployment passenger airbag system, to deploy the cushions of the top and mid airbags substantially horizontally towards a passenger seat when a vehicle accident occurs, the distance between the top airbag and the mid airbag is within a range from 100 mm to 250 mm, the top airbag is inclined at an angle ranging from 60° to 75° with respect to the horizontal surface, and the mid airbag is inclined at 15° or less with respect to the horizontal surface.
