A driver airbag cushion includes a front panel and a rear panel that are joined together along a joined perimeter to form an airbag cushion. The airbag cushion is shrunken in diameter along the joined perimeter by a means of a short rope, a group of pleats, or a group of short tethers to form a spool shaped airbag cushion when fully inflated with a recess along the perimeter outside the airbag cushion. The airbag volume is reduced by 20 to 30% while keeping or improving the effectiveness of the occupant protection. The inflator output is significantly reduced so that a low output single stage inflator can be used.

Spool airbag

A passenger airbag system includes an airbag cushion with an upper airbag chamber and a lower airbag chamber. The front face of the lower airbag chamber has an upper edge joined to the lower face of the upper airbag chamber at a connection region. An upper airbag chamber length is defined as a horizontal distance between the portion of the front face of the upper airbag chamber closest to the passenger and the portion of the mid portion of the instrument panel closest to the passenger. A lower airbag chamber front offset is defined as a horizontal distance between the portion of the front face of the upper airbag chamber closest to the passenger and the connection region. The lower airbag chamber front offset is at least 25% of the upper airbag chamber length.

Mushroom airbag

A passenger airbag system is designed for an automotive vehicle with a passenger compartment, a windshield and an instrument panel disposed between the passenger compartment and the windshield. The instrument panel has a top portion adjacent the windshield, a lower surface generally directed toward the legs of an occupant and a mid-portion with a surface that extends between the top and lower portions. The system includes a first airbag and a second airbag both disposed in the instrument panel. Each airbag has a cushion deployable from the housing through the instrument panel along a predetermined path for direct contact with an occupant seated in the passenger compartment. The second airbag has a lower portion when deployed that fills a space between the occupant's lower extremities and the lower portion of the instrument panel and thus acts as a knee airbag.

Low risk deployment passenger airbag system with knee protection

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&#xb0; to 75&#xb0; with respect to the horizontal surface, and the mid airbag is inclined at 15&#xb0; or less with respect to the horizontal surface.

Low risk deployment passenger airbag system using slim type passenger airbag module

A passenger airbag system is designed for an automotive vehicle with a passenger compartment, a windshield and an instrument panel disposed between the passenger compartment and the windshield. The instrument panel has a top portion with a surface which is more horizontal than vertical and generally directed toward the windshield and a mid-portion with a surface that is more vertical than horizontal and generally directed toward an occupant of the passenger compartment. The system includes a single airbag housing that is disposed in the instrument panel and extends from the top portion to the mid-portion. The airbag cushion is deployable from the housing through the instrument panel along a predetermined path for direct contact with an occupant seated in the passenger compartment. The predetermined path is generally radial with respect to the surface of the instrument panel.
