The methods for folding an airbag cushion into a housing provide for a predetermined deployment trajectory. The airbag cushion is defined by an upper panel and a lower panel. A first portion of the airbag cushion is tucked into a second portion of the airbag cushion such that the upper and lower panels of the first portion are positioned in between the upper and lower panels of the second portion. The tucked portion is folded in towards the housing. First and second halves of the tucked airbag cushion are folded in towards the housing. Finally, the folded first and second halves of the airbag cushion are folded into the housing.

Airbag cushion folding methods

Methods are provided for folding an airbag cushion into a housing. In one implementation of the inventive method, an airbag cushion defined by an upper panel and a lower panel is provided. A first portion of the airbag cushion is tucked into a second portion of the airbag cushion such that the upper and lower panels of the first portion are positioned in between the upper and lower panels of the second portion. The tucked portion is folded in towards the housing. First and second halves of the tucked airbag cushion are folded in towards the housing. Finally, the folded first and second halves of the airbag cushion are folded into the housing.

Disclosed are embodiments of methods for folding an airbag cushion into a housing.

Finally, the folded first and second halves of the airbag cushion are folded into the housing.

Airbag cushion folding method

An airbag cushion venting system is disclosed. The system comprises an airbag cushion body having a cushion vent formed therein. A vent cover is attached to the body such that the vent cover at least partially covers the cushion vent in its unconstrained state. A tieback structure holds the vent cover either away from the cushion vent opening or in a position such that a smaller portion of the cushion vent is covered than is covered in the cushion vent's unconstrained state and is adapted to release the vent cover once the body has expanded a sufficient amount to enable the vent cover to at least partially cover the cushion vent.

Cushion venting design for out of position occupant protection

An airbag module may include an inflator, a cushion, and a deflection hood. When used as a passenger side, frontal impact module, the cushion deploys upward from a vehicle instrument panel. The deflection hood directs gas downward through a discharge opening and into the cushion to expedite inflation of the lower portion of the cushion to more uniformly cushion a vehicle occupant's body. The discharge opening may be sewn shut via a tear seam to ensure that the discharge opening is properly positioned when the tear seam opens to release inflation gas. Alternatively, the discharge opening may be sewn shut by a non-tearable seam, and perforations may be applied proximate the non-tearable seam so that the discharge opening opens along the perforations to release the inflation gas. According to one alternative, the deflection hood may be angled within the cushion to provide a significant asymmetrical, lateral gas flow.

Gas flow deflection apparatus and method for airbag systems

The inflatable cushion of the present invention includes at least two panels and one or more heat shield strips. Each panel has an inflatable region, an attachment region, and a peripheral edge. The attachment region is positioned between the peripheral edge and the inflatable region of each panel. An inward fold is disposed between the inflatable region and the attachment region of each panel. The attachment regions of each panel are disposed proximate each other. A heat shield strip is disposed on a portion of the attachment region and the inflatable region of the same panel. A secure fastener secures the attachment regions of each adjacent panel together and secures the heat shield strip to the attachment region on which it is disposed. A frangible fastener secures the heat shield strip to the adjacent inflatable region on which it is positioned.

Inflatable cushion with shielded seams

An airbag cushion for protecting an occupant of a vehicle from an impact is presented. The airbag cushion has an inflatable region which inflates upon the reception of an inflation gas from an inflator. The airbag cushion is secured to a housing by a retaining member. The retaining member is configured to secure an attachment region of the airbag cushion to the housing by the use of fasteners which create a clamping force. The clamping force is highest adjacent the fasteners and is lowest at positions between the fasteners. Thus, a high clamp region is created adjacent the fasteners and a low clamp region is created at positions distant from the fasteners. As the airbag cushion is inflated, a load force puts tension on the attachment region of the airbag cushion potentially ripping the airbag cushion out from the low clamp regions. A load controlling cutout is positioned within the attachment region and between the fasteners. The load controlling cutout is configured to shift the load force the low clamp region to the high clamp region during inflation of the inflatable region.
