Abstract:
An airbag assembly may include an inflatable curtain airbag with a stowed configuration and a deployed configuration. The inflatable curtain may have a first protection zone and a second protection zone that inflates forward or rearward of the first protection zone to provide enhanced protection. The second protection zone may be double-folded against the first protection zone so that, during deployment, the second protection zone pivots to unfold relative to the first protection zone. Attachment features such as tack stitching may be used to secure the folded portions together. The tack stitching may be designed to break during deployment of the airbag such that the first protection zone inflates first, followed by a proximal portion of the second protection zone, and then by a distal portion of the second protection zone.
Abstract:
An airbag can include a first cushion portion that defines a first inflatable chamber and a second cushion portion that is connected to the first cushion portion and defines a second inflatable chamber. The first inflatable chamber can receive inflation gas from an inflator to expand the first cushion portion, and the second cushion portion can receive inflation gas from the first inflatable chamber to expand the second cushion portion. A one-directional valve permits inflation gas to flow from the first inflatable chamber to the second inflatable chamber and restricts backflow of inflation gas from the second inflatable chamber to the first inflatable chamber.
Abstract:
An airbag module assembly includes a module housing that defines a storage chamber. A thrust neutral inflator device is at least in part disposed within the storage chamber. The inflator device releases airbag inflation gas within the storage chamber in a cross-car manner. In specific embodiments, the cross-car release of the airbag inflation gas involves substantially all the airbag inflation gas being released at an angle of no more than ±60° and preferably at an angle of no more than ±50° from horizontal when viewed in a top planar view of the inflator device disposed within the housing.
Abstract:
A restraint device for restraining an occupant in a vehicle includes a belt, an inflator, a gas guide, and a flexible tether. The belt includes a first layer, a second layer, and a seal between the first and second layers. The first and second layers extend from a first end of the belt to a second end of the belt. The seal cooperates with the first and second layers to form an inflatable portion of the belt. The inflator is operable to provide pressurized gas. The gas guide has a first end placed over an outlet of the inflator and a second end extending into the inflatable portion of the belt. The flexible tether secures the gas guide to the belt.
Abstract:
Apparatus, methods, and systems for deflecting a vehicle wheel away from a foot well to reduce the chances for intrusion into the foot well during certain collisions, such as foot well intruding impact events. In some embodiments, the system may comprise an expandable structure comprising a rigid material. The expandable structure may be configured to be positioned in a wheel well of a vehicle and may be configured to actuate from a first, contracted configuration to a second, expanded configuration, and to deflect a vehicle wheel away from a foot well of the vehicle during an impact event to reduce the chances of the vehicle wheel entering the foot well during the impact event. The system may further comprise an inflator configured to deliver a fluid to the expandable structure during actuation so as to expand the expandable structure from the first configuration to the second configuration.
Abstract:
An airbag can include a first cushion portion that defines a first inflatable chamber and a second cushion portion that is connected to the first cushion portion and defines a second inflatable chamber. The first inflatable chamber can receive inflation gas from an inflator to expand the first cushion portion and the second cushion portion can receive inflation gas from the first inflatable chamber to expand the second cushion portion. In some arrangements, a temporary fastener may maintain the second cushion portion in a compact state during expansion of the first cushion portion.
Abstract:
Apparatus and methods, and systems relating to flat panel airbag cushions that may be particularly useful in connection with passenger-side airbag systems. Some embodiments may comprise a first panel and a second panel having a larger cross-sectional area than the first panel in an unfolded state. The second panel may comprise a first set of pleats and a second set of pleats configured such that, upon inflation of the airbag cushion, the first set of pleats and the second set of pleats unfold to define a three-dimensional airbag cushion. The second panel may be sewn or otherwise attached to the first panel about a periphery of the two panels.
Abstract:
An electronic module and method of making an electronic module include a printed circuit board (PCB) having a surface, at least one conductive trace being formed on the surface. A housing element for mechanically mating with the PCB includes at least one mating surface aligned with the conductive trace on the PCB when the PCB and the housing element are mechanically mated, the mating surface comprising a plurality of alternating protrusions and spaces between the protrusions. An electrical gasket is formed on the mating surface of the housing element such that the electrical gasket conforms with the protrusions and spaces on the mating surface of the housing element and is disposed between the mating surface of the housing element and the conductive trace on the surface of the PCB when the housing element and the PCB are mechanically mated, such that the electrical gasket provides an electromagnetic interference (EMI) seal between the mating surface of the housing element and the conductive trace on the first surface of the PCB.
Abstract:
A steering wheel is provided that may include a central member, a rim, a structural member, a switch-frame and a switch assembly. The rim may be spaced apart from the central member. The structural member may extend between the central member and the rim. The switch-frame may be secured relative to the structural member and may include first, second, and third members cooperating to define an opening. The first member may be disposed between the central member and the rim and may extend laterally across the structural member. The second and third members may be spaced apart from each other and may extend from the first member toward the rim. The switch assembly may be mounted to the switch-frame and may at least partially extend through the opening.
Abstract:
An airbag assembly may include an inflatable curtain airbag with a stowed configuration and a deployed configuration. The inflatable curtain may have a first chamber and a second chamber that inflates forward of the first chamber. The second chamber may be separated from the first chamber by a non-inflating region. The non-inflating region may have a width selected such that in-plane bending of the inflatable curtain occurs during deployment. The in-plane bending may position the second chamber lower than the first chamber such that the second chamber overlaps a significant portion of a door adjacent to the inflatable curtain. Forward and rearward portions of the non-inflating region may be attached together to form a fold that decreases the width of the non-inflating region, thereby enhancing the in-plane bending. The second chamber may also bend out-of-plane relative to the first chamber to help provide protection in small overlap collision situations.
