Problems solved by technology

However, as of today, none of these technologies has been proven to work reliably enough to reduce injury to young children and infants in rearward-facing child seats to the level that would qualify as a low-risk deployment option Standard level, while still protecting a properly positioned adult in a severe crash

Embodiment Construction

[0027] Referring to FIG. 1 , therein a conventional single passenger air bag module is shown top mounted within the instrument panel. The airbag cushion 3 is deployed toward the head and torso portion of the adult passenger 2 . During the deployment of the airbag, as indicated by the dotted line, the airbag will generate a considerable downward deployment component, as indicated by arrow 6 . The downwardly deployed component 6 will push down the head of the child 1 who is not in the proper position and potentially cause serious injury to the neck. The airbag module has a gas generating inflator 4 and a cover 5 holding the inflator 4 and the airbag cushion 3 .

[0028] FIG. 2 shows another conventional single passenger airbag module centrally mounted in the dashboard. The airbag module includes an airbag cushion 7 deployed toward the head and torso portion of the adult passenger 2 . During airbag deployment, as indicated by the dotted line, the airbag 7 will have a considera...

Abstract

A low risk deployment passenger airbag system has two separate airbags, a top-mounted airbag 11 and a mid-mounted airbag 12. The top-mounted airbag 11 deploys into the adult occupant's head and upper torso areas without generating substantial downward deployment, while the mid-mounted airbag 12 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. The top-mounted airbag 11 has a larger capacity in volume than the mid-mounted airbag 12 and serves as a main airbag for protecting in-position occupants. The mid-mounted airbag may be deployed at low output or no output level for belted occupants during high-speed crashes, which in turn can help reduce the injury values of an infant dummy in a rear facing child seat during the low risk deployment test.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Patent Application Nos. 10 / 909,581, filed August 2, 2004, and 60 / 577,569, filed June 7, 2004, 60 / 581,919, filed June 22, 2004, and Priority to US Provisional Patent Application No. 60 / 628,434, filed November 15, 2004, the entire contents of the above related applications are hereby incorporated by reference. technical field [0003] The present invention relates to passenger airbag systems for use in motor vehicles. Specifically, the two airbags are mounted separately in the dashboard to minimize the risk of injury to out-of-position occupants when the airbags inflate, while inflicting damage on in-position occupants in a severe crash like a conventional single airbag for effective protection. Background technique [0004] Front driver and passenger air bags have saved many lives and reduced injuries in severe frontal collisions. These airbags have been proven to work effectively with se...
