Abstract: An inflator device for an inflatable cushion restraint system. The inflator device includes a housing at least in part defining a chamber containing a stored gas. The housing includes a first outlet orifice and a second outlet orifice. A first rupturable seal is disposed over the first outlet orifice and a second rupturable seal is disposed over the second outlet orifice.

Additionally, a spring is disposed between the buckle attachment plate and the head of the fastener. Further, the through aperture in the buckle attachment plate is oversized such that the buckle attachment plate and attached buckle can rotate along a longitudinal axis of the fastener.

Abstract: An airbag inflation deflection device and airbag module is disclosed. The deflection device may be a deflection hood that covers a portion of the airbag inflator, and is positioned adjacent inflator exit ports to initially deflect inflation gas away from an intended occupant position. The airbag module also includes a housing that may have side wells on either side of the inflator, in which the deflection hood initially deflects the inflation gas. The housing and deflection hood in combination may direct a majority of the inflation gas into the lateral portions of the airbag instead of into the center portion.

Abstract: A multi-composition pyrotechnic material is provided for an inflatable restraint device (for example, an airbag system or pretensioner for a vehicle). The multi-composition pyrotechnic material can be a gas generant, a micro gas generant, or an igniter, for example. The multi-composition pyrotechnic material comprises a first pyrotechnic material that defines one or more void regions. A second pyrotechnic material, compositionally distinct from the first pyrotechnic material, is introduced into at least one of the void regions and forms a second region of the pyrotechnic materials. The second composition can be introduced to the void regions in the form of a slurry. Methods of forming such multi-composition pyrotechnic materials are also provided.

Abstract: An airbag assembly is disclosed for use in an automobile. The disclosed airbag assembly adaptively vents gas from the interior of the airbag depending on whether an obstruction is encountered during airbag deployment.

Abstract: A process of determining target parameters of an object within a field of detection of an automotive radar system, the process comprising the steps of: (a) establishing a target range from a sequence of ranges; (b) dwelling on the target range for an initial dwell time to obtain sensor data; (c) determining if the sensor data corresponds to the presence of an object or to the absence of an object at the target range based on probability density distributions of an object being present and being absent at the target range, and if such the determination cannot be made, then repeating steps (b)-(c) until the determination can be made; (d) if the sensor data is determined to correspond to the presence of an object in step (c), then dwelling at the target range for an extended dwell time to obtain additional sensor data for determining the target parameters of the object before proceeding to step (e); and (e) establishing the next of the sequence of ranges as the target range before reiterating steps (b)-(e).

Abstract: An inflator device for inflating an inflatable cushion of an inflatable cushion restraint system. The inflator device includes a supply of gas generant material disposed within a sealed chamber, and an initiator device in reaction initiation combination with the supply of gas generant material. A venting orifice connects the chamber to the surrounding ambient environment, and a rupturable seal seals the venting orifice. Upon reaction initiation of the gas generant material to produce inflation gas, the rupturable seal ruptures to vent the chamber to the ambient environment. A valve assembly can be disposed adjacent the venting orifice. A moveable valve piston, in combination with an actuator device, can block the venting orifice as needed to close the venting orifice and stop inflation gas venting. An optional tether release mechanism can be used in combination with the valve assembly to release a cushion tether upon closing of the venting orifice.
