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.
摘要:
Inflator device assemblies containing an expandable fluid effective to provide a gaseous inflation medium also advantageously employ or incorporate a pyrotechnic material such as to augment or enhance at least one fill characteristic of the gaseous inflation medium. The pyrotechnic material is provided on a selected non-gas generant surface within the inflator device. Suitable pyrotechnic compositions may include a binder additive effective to adhere the pyrotechnic composition to a surface within the inflator device.
摘要:
A method for introducing a radioactive leak trace material into an apparatus for inflating an inflatable device is disclosed in which a mixture containing a preselected quantity of the radioactive leak trace material and a quantity of at least one gas source material, which upon initiation results in an inflation fluid used to inflate the device, are loaded into a chamber of the apparatus.
摘要:
An improvement in an airbag system for a motor vehicle relating to an adaptive output fluid fueled airbag inflator and method of operation thereof are provided. Such an inflator, in addition to a stored gas chamber, a combustion chamber wherein, upon actuation, a first fluid fuel and an oxidant are burned, and a first initiator device for initiating the combustion of the first fuel and the at least one oxidant, includes a combination of a fluid fuel container, which holds a supply of a second fluid fuel, and a second initiator device for initiating the combustion of the second fuel. Various selected performance levels can be obtained through the proper selection, actuation and sequencing of actuation of the initiator devices and burning of fuels contained within the inflator.
