  • Patent number: 9022422
    Abstract: 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.

  • Patent number: 8414022
    Abstract: 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.

  • Patent number: 7731229
    Abstract: 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.

  • Publication number: 20090200774
    Abstract: A side head airbag is installed in a headrest of a vehicle seat and deploys laterally forward with respect to the vehicle toward a gap located between an occupant's head and a side window for the protection of the occupant's head during a serious side impact crash. The side head airbag has a tether constructed in such a way as to minimize the inefficient voids that are commonly seen from side curtain airbags. The side head airbag may have a two chamber construction to improve the energy absorption mechanism from an elastic loading/unloading to a plastic loading/unloading along with a roll-over protection. Another restraint may be installed, separately from the head airbag, in a seatback or in a side structure to protect an occupant's thorax and/or pelvis during a serious side impact crash.

  • Publication number: 20090160171
    Abstract: A driver airbag includes a front panel facing a driver and an opposite rear panel. Each panel has a central region and a perimeter with a center point being defined at the geometric center of the panel. The perimeters of the front and rear panels are joined to provide an airbag outer shell. A lower tether has a first end secured to the central region of the front panel and a second end being secured to the central region of the rear panel. An upper tether or membrane has a perimeter that is secured to the front and rear panels above the center points thereof. A lower chamber is defined by and below the upper tether and an upper chamber is defined by and above the upper tether. The upper tether has an opening defined therethru for gas to flow from the lower chamber to the upper chamber.

  • Patent number: 7328913
    Abstract: 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.

  • Patent number: 7070201
    Abstract: A low risk deployment passenger airbag system has two separate airbags, a top-mounted airbag and a mid-mounted airbag. The top-mounted airbag deploys into the adult occupant's head and upper torso areas without generating substantial downward deployment, while the mid-mounted airbag deploys into the adult occupant's lower torso area without generating substantial upward deployment. This mode of substantially horizontal deployments can provide an out-of-position child with a safe mode of airbag inflation, reducing the risk of neck injuries. An infant in a rear facing child seat receives distributed small forces from two airbags with a possible time delay in initial airbag contact rather than a concentrated large force from the conventional single passenger airbag. The total capacity of the two airbags is about the same as the conventional single passenger airbag and thus can provide as effective protection.
