摘要:
A hybrid inflator for a vehicle airbag module produces an initial release of essentially unheated, stored, pressurized gas from the gas storage chamber of the inflator by way of a projectile, releasable from a nozzle opening in a combustion chamber housing upon combustion of a gas-generating combustible material housed within the combustion chamber housing, which ruptures and passes through a frangible burst element retaining the stored, pressurized gas in the gas storage chamber of the inflator, thereby permitting, initially, the unheated, stored, pressurized gas to discharge through the ruptured burst element and flow externally past the combustion chamber housing in an isolation housing and then to exit the inflator through gas exhaust ports in the inflator.

A passenger side airbag module includes a reaction canister whose sidewalls define a pair of channels on opposite sides of its open mouth. An unperforated cushion cover carries a pair of splines which are engaged by the channels. One spline/channel combination locks the cover securely to the canister. The other spline/channel combination forms a snap-fit engagement which disengages under the force of the expanding airbag.

A device for securing a passenger-side inflator to a module housing without the use of fasteners or special tools is disclosed. An elastically flexible tab formed into one wall of the canister and placed at an angle of about 3.degree. to about 45.degree. engages with a boss or recessed section at one end of the inflator. A raised section may be formed in the base of the inflator, which raised section engages with the outer wall of the inflator causing it to further engage with the canister.

A deep drawn reaction canister encloses a hybrid inflator. In order to evenly inflate an airbag, a diffuser sheet is positioned over the inflator to distribute the gases which exit one end of the inflator. The diffuser sheet serves a second function of securing the inflator in the canister. It does so by means of screws which extend through the canister and into threaded engagement with the diffuser sheet, placing it in tension when the screws are tightened.

Disclosed are methods, systems, and apparatus for inflating airbags. In one embodiment, an initiator is deployed to open an exit gas port, through which the airbag is inflated. The airbag is primarily inflated via gas from a first gas chamber and is substantially maintained in an inflated state for a predetermined period of time primarily via gas from a second gas chamber. In one embodiment, an airbag inflator is provided which comprises a first gas chamber, a second gas chamber, and an intermediate chamber assembly. The intermediate chamber assembly comprises a first gas port positioned adjacent to and in fluid communication with the first gas chamber and a second gas port positioned adjacent to and in fluid communication with the second gas chamber. The inflator is configured to allow a greater flow rate of gas through the first gas port upon deployment than through the second gas port.

The improved steering apparatus is an invention that increases vehicular operational safety by providing means for a vehicle operator to control various vehicle functions and accessories while keeping both hands on the steering apparatus. The apparatus also automatically provides for the display of a variety of driver relevant information including automatic live video (160) feed of blind spots, rear vehicle cabin area, and road sign information (320), by displaying the information on the steering apparatus mounted video screen. The apparatus includes a built-in speaker (170) and is controlled by either voice commands or by a touching of the touch activatable video display screen (160).

Disclosed are embodiments of an airbag tether release mechanism for use with airbag inflation systems. In one embodiment, the mechanism includes an initiator positioned within a housing. The initiator is configured such that it provides an inherent seal to prevent the external release of pyrotechnic residues upon deployment. The device may also include a cutter operatively connected with the initiator such that deployment of the initiator actuates the cutter and a tether restraint structure configured to secure a tether until the tether is released by actuation of the cutter.

A method of generating a file suitable for programming a programmable logic device. The method generally comprises the steps of (A) generating a programming item from a plurality of parameters that define a program for the programmable logic device, (B) storing the programming item in a programming field of the file in response to generating, and (C) storing at least one of the parameters in a non-programming field of the file.
摘要:
An airbag or inflatable curtain inflator for producing two differing gas flows is disposed. The inflator has a gas chamber, a first orifice, and a second orifice. The first orifice has a different effective cross-sectional area than the second orifice. The two different cross-sectional areas allow the first orifice to produce a mass flow rate of gas that is different from the second orifice. The mass flow rates of gas may be related to the volume of an inflatable curtain into which the gas is ejected. Thus, two differently sized volumes of an inflatable curtain may be simultaneously inflated with a single inflator.
