Embodiment Construction

[0025] refer to Figure 1 to Figure 2 , according to an exemplary embodiment, a motor vehicle 10 includes an airbag system 100 . The airbag system 100 generally includes an airbag cushion 110 disposed in a housing 140 between an occupant 14 and a reactive surface 12 of the vehicle 10 (such as a dashboard, headliner, pillars, etc.). The airbag system 100 is generally hidden from view, such as behind a dashboard panel, roof or trim in a pillar, or under seat fabric. The inflator 150 is arranged in fluid communication with the airbag cushion 110 such that when triggered, the inflator 150 discharges inflation gas to rapidly inflate the airbag cushion 110 . A control system 102 is provided for the airbag system 100 that triggers the inflator 150 upon detection of certain predetermined conditions, such as rapid deceleration or acceleration events and / or occupant characteristics. Such predetermined conditions may be detected by sensors included in the airbag system 100 or the contr...

Abstract

According to an exemplary embodiment, an airbag system includes an airbag cushion, a housing, an inflator, a latch mechanism, and a valve panel. The airbag cushion defines an inlet and a chamber. The house is coupled to the airbag cushion generally proximate the inlet. The inflator is coupled to the housing and is in fluidic communication with the inlet. The latch mechanism is coupled to the housing. The valve panel has a first end coupled to the airbag cushion generally opposite the inlet and includes a second end releasably coupled to the latch mechanism. The airbag cushion includes one or more vent apertures through a surface thereof. The valve panel includes one or more valve apertures and is disposed in the chamber generally adjacent the surface of the airbag cushion. The valve panel is configured to slide relative to the airbag cushion from a first position to a second position before being released by the latch mechanism to move to a third.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Non-Provisional Application Serial No. 13 / 182,223, filed July 13, 2011, which is incorporated by reference in its entirety into this disclosure. technical field [0003] The present disclosure relates to air bags. More specifically, the present disclosure relates to air bags for protecting motor vehicle occupants in the event of an accident. Background technique [0004] Air bag modules or systems (e.g. side impact, front impact air bag modules or systems) located in vehicles to restrain or otherwise protect occupants (e.g. driver, passenger) during vehicle dynamic events (e.g. frontal impact, side impact, rollover events, etc.) be protected from collision or injury. Airbag systems generally include an inflatable airbag cushion and an inflator. Upon detection or occurrence of a power event, the inflator is triggered to release or otherwise generate inflation gas that is dir...
