Abstract:
Enhanced airbag modules and associated methods are provided. An airbag module according to the invention may have a cushion with a venting portion. During normal vehicle operation, the venting portion may be closed so that inflation gas is not permitted to flow through the venting portion. A pyrotechnic may be ignited to open the venting portion when venting is desired. The pyrotechnic may be directly attached to the venting portion to burn through or mechanically rupture the venting portion, thereby forming an exit port. Alternatively, the venting portion may have a flap that can be detached from the housing by ignition of a pyrotechnic to permit venting through an exit port of the housing. The pyrotechnic may then be disposed within a fastener designed to fracture upon ignition of the pyrotechnic to release the flap from attachment to the housing. The pyrotechnic may, for example, be an initiator or rapid deflagration cord (RDC). The cushion may thus be more stiffly inflated for a high velocity collision, or less stiffly inflated in the case of a lower impact velocity or an out-of-position occupant.
Abstract:
Airbaggerät, Folgendes umfassend: eine Airbagabdeckung (10), die mehrere Beine (22) hat, die sich von einer Frontabdeckung (14) nach hinten erstrecken, wobei jedes der Beine (22) eine erste und eine zweite Nase (34, 38) aufweist; einen Rückhalter (46), der mehrere Schlitze (50) hat, wobei jedes Bein (22) ausgerichtet ist, um durch einen getrennten Schlitz (50) durchzutreten; und eine Rückhalteplatte (82), die an dem Rückhalter (46) befestigt ist, wobei die erste Nase (34) den Rückhalter (46) überlappt und einen widerstehenden Eingriff mit diesem bereitstellt, um die Airbagabdeckung (10) daran zu hindern, sich während des Entfaltens des Airbags (54) vom Rückhalter (46) und von der Rückhalteplatte (82) zu trennen, und wobei die zweite Nase (38) die Rückhalteplatte (82) überlappt und einen widerstehenden Eingriff mit dieser bereitstellt, um dem Abtrennen der Airbagabdeckung (10) während des Entfaltens des Airbags (54) vom Rückhalter (46) und von der Rückhalteplatte (82) zu widerstehen, wobei sich erste und zweite Nase (34, 38) in entgegengesetzte Richtungen erstrecken, dadurch gekennzeichnet, dass sich beide Nasen (34, 38) auf der selben Seite des Rückhalters (46) befinden, nämlich auf der der Frontabdeckung abgewandten Seite des Rückhalters.
Abstract:
An airbag module for installation in a motor vehicle is disclosed. In an exemplary embodiment, the airbag module includes an airbag cushion. A diffuser is positioned inside the airbag cushion. The diffuser includes a diffuser panel that has a plurality of venting apertures disposed throughout. An inflator is provided for inflating the airbag cushion. The inflator includes an inflation gas dissemination portion that releases inflation gases upon activation of the inflator. The inflator is attached to the diffuser in such a way that the inflation gas dissemination portion of the inflator is located inside the airbag cushion.
Abstract:
An airbag apparatus including an airbag cover is disclosed. The airbag cover is designed to match the décor of the vehicle and to prevent the occupant from viewing the undeployed airbag system. The airbag cover has a front panel and a plurality of legs. The plurality of legs that extend rearward of a front panel. An airbag retainer is also added to the apparatus. The retainer has a plurality of slots and is designed such that each leg is oriented to pass through a separate slot. The airbag apparatus also includes a retention plate attached to the retainer. Each of the legs includes a first ear and a second ear. The first ear overlaps and provides resistive engagement with the retainer to prevent the cover from separating during deployment. Similarly, the second ear overlaps and provides resistive engagement with the retention plate to resist separation of the cover during deployment.
Abstract:
An airbag assembly is disclosed. The airbag assembly includes an inflatable cushion having a recess in its lower portion. The recess may form split sections in the lower portion of the cushion. The recess may be configured to receive a rear-facing child car seat during deployment. The airbag assembly may further include a tethering system to control deployment of the split sections of the cushion.
Abstract:
An airbag cushion is disclosed for use in automotive protective systems. The airbag cushion includes a vent flap that, prior to cushion deployment, extends from the cushion exterior through a vent. A strap is coupled to the vent flap and to an interior surface of the cushion. Upon airbag deployment, the strap extends until taut or extends until the cushion encounters an obstruction. If pulled taut, the strap pulls the vent flap into the cushion interior where the interior air pressure effectively presses the vent flap against the vent. If the cushion encounters an obstruction, the strap remains lax, and the vent remains open. Means are provided for retaining the vent in the closed position during occupant ride down.
