Such igniter assemblies can comprise an adaptor, an ignition portion and a plurality of conductors coupled to the ignition portion and extending in a first direction from the ignition portion to an opening of the adapter. A connector is adapted to be slid into the opening in a second direction which is transverse to the first direction associated with the extension of the conductors from the ignition portion to the opening of the adapter. Igniter assemblies can be coupled with a body of an inflatable airbag system inflator, which inflator body may enclose a quantity of gas generant.

Abstract: The disclosure provides an inflator device for a passive restraint device, like an airbag. In certain aspects, a fuel-rich gas generant grain is located in actuating proximity to an initiator device. The grain has at least one flow channel through which a shock wave generated by the initiator device passes. The shock wave opens a burst disc between the inflator housing and downstream airbag to permit gases to flow into the airbag. A chamber storing pressurized gas (having at least one oxidant, e.g., O2) is also disposed within the inflator. Upon initiator actuation, the oxidant can react with combustion products of the initiator and the fuel-rich gas generant and flow into the airbag for rapid inflation. Methods of inflating airbags and improving airbag deployment reliability are provided. Such inflators are particularly suitable for large volume (greater than 60 liter) airbags.

Abstract: A sensor assembly for a motor vehicle adapted for sensing impacts including pedestrian impacts. The sensor assembly integrates functions of pressure based sensors used in one embodiment with a compressible tube extending laterally across the front surface of the vehicle and the outboard front boundary areas of the front end of the vehicle. Both acceleration and pressure based sensors are mounted into an integrated sensor housing which is mounted in a desired position at the vehicle front fascia front boundary areas. The system optimizes pressure based sensing while providing acceleration based sensing at the lateral boundary areas where supporting structure does not enable pressure based sensing. The invention further including sensor arrangements including discrete pressure and acceleration sensors deployed for detecting pedestrian impacts at the center and front boundary areas of the vehicle front end.

Abstract: An initiator assembly can include an outer body can have a first end, a second end, and an internal passage between the first and second ends. An initiator canister can be joined to the outer body at the first end and can define a charge chamber that includes a pair of pins extending therefrom. An insulative material can be molded within the passage to form an insulative structural member that joins the canister and pins to the outer body and insulates the pins and a portion of the canister from electrical contact with the outer body. An electrostatic discharge dissipater can be formed from an electrically conductive material and can be molded to the outer body. The dissipater can provide a controlled dissipation path for electrostatic discharge energy carried by the initiator assembly.

Abstract: A seat belt retractor for providing extraction and retraction of seat belt webbing incorporating a belt tension sensing mechanism. The sensing mechanism includes a webbing guide which is moveable between positions and is biased toward a low tension position by a restoring spring force. The belt webbing is routed to deflected path through the web guide. Increasing tension on the webbing will cause the web guide to change its position as the webbing path straightens. The position of the web guide is detected through an electrical switch to provide a measure of webbing tension.

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 of the first protection zone to provide enhanced protection. The second protection zone may be folded against the first protection zone so that, during deployment, the second protection zone pivots to unfold relative to the first protection zone. The airbag assembly may have a restraint member that limits the ability of the second protection zone to unfold to a configuration parallel to the first protection zone, thereby keeping the second protection zone at an optimal location to protect the vehicle occupant from rollover and/or small overlap or oblique collisions. The restraint member may be a tether with ends secured proximate the top of the second protection zone and the top of the first protection zone.

Abstract: A frontal airbag has a first section, a second section, and a third section, the second section being in fluid communication with both the first and the third section. The first, second and third sections form a triangular structure upon inflation of the airbag. A gas generator is attached to the first section and in fluid communication with the first section. An end portion on the third section remote from the second sections attached to the first section in an area between the gas generator and the second section. Two side tethers attached to the first section and to one of the second and third sections or near transitional bend between the second and third section provide resistance against flattening of the airbag after inflation. The first section and the third section are directly attached to each other by a seam, by an adhesive, or by lamination.

Abstract: A dual-mode retractor for an automotive seat belt webbing is configured to switch between a first mode and a second mode, the first mode being one of an ELR mode and an ALR mode, and the second mode being the other one of the ELR mode and the ALR mode.

The magnetic field of a permanent magnet mounted on the first part is picked up by a Hall effect sensor. An interrupter plate is mounted on the second part in a position relative to the magnet, in which the interrupter plate, in which the interrupter plate exposes the HED to the original magnetic field in the first mode and to a modified magnetic field in the second mode.

Abstract: An energy absorber includes opposing aligned crush lobes expandable in opposite directions, and when expanded, potentially collapse with different energy-absorbing rates and stroke distances. The energy absorber forms a subassembly design that is adaptable and easily modified for predetermined energy absorption crush curves and specific energy-absorbing circumstances, such that it can be used inside a vehicle passenger compartment or outside a vehicle in different locations, such as for a knee bolster on the instrument panel, or on a door inner panel, or on an under-knee seat component, or on a headliner or A-pillar cover, or hood-lifter for pedestrian safety. One version of the energy absorber includes formed sheets bonded along a perimeter to define two cavities and an inflator-holding pocket connected to the cavities by integrally-formed tunnels.

Abstract: An inflatable side airbag has an inflatable duct for the delivery of inflation gas. The inflatable duct of the inflatable side airbag provides for rapid deployment of a multi-chamber air bag while controlling the rate of inflation and the relative pressure of the chambers. The inflatable duct allows a single inflator to inflate a high pressure pelvis chamber and a lower pressure thorax chamber while preventing fluid communication between the two chambers upon completion of inflation.

Abstract: A linear pretensioner device for motor vehicle belt restraint systems of the type mountable to a motor vehicle structure and coupled with a belt restraint system component. In one form, the linear pretensioner includes a stroking housing forming a bore and a cable coupled with the stroking housing and to the belt restraint component. A main housing adapted to be fixed to the motor vehicle structure is positioned within the bore of the stroking housing, with the stroking housing telescopically overfitting the main housing. The main housing and the stroking housing form an expanding chamber that enlarges when pressurized by a gas generator. Upon activation, the gas generator drives the stroking housing along the main housing to exert tension on the cable. In another form, the pretensioner has an inner housing positioned within a bore of an outer housing, and the cable is coupled with the inner housing.
