Abstract: Cool burning gas generant compositions for an automotive inflatable restraint system are provided that include a bismuth-containing compound selected from the group consisting of: bismuth citrate, bismuth subsalicylate, bismuth hydroxide, copper bismuth hydroxy nitrate, bismuth subcarbonate, bismuth suboxalate, and combinations thereof. The gas generant comprises at least one copper-containing component. The gas generant includes at least one oxidizer, fuel, and optional coolant. The maximum flame temperature at combustion (Tc) of less than or equal to about 1700K (1,427° C.). The cool burning gas generant composition generates liquid phase combustion products making it suitable for use in a filterless inflatable restraint system. Copper and bismuth present in the cool burning gas generant composition react to form an alloy having a melting point at or near the maximum flame temperature at combustion (Tc).

Abstract: An inflator for generating inflation gases for a safety device includes a housing having an internal cavity including a combustion chamber and a filter chamber. A filter is disposed in the filter chamber. A separating member is disposed in the housing on a first axial side of the filter and separates the filter chamber from the combustion chamber. An insulating member is disposed in the filter chamber on a second axial side of the filter. The second axial side is opposite the first axial side. The separating member is coupled to the insulating member.

Abstract: Airbag assemblies, such as overhead airbag assemblies, comprising overlapping pass-through chambers. In some embodiments, the assembly may comprise an airbag cushion configured to deploy from a vehicle roof structure and a head contact chamber configured to engage a head of an occupant of the vehicle upon deployment. An opening may be formed within the airbag cushion adjacent to the head contact chamber and may extend from a first surface of the airbag cushion configured to engage the occupant to a second surface of the airbag cushion opposite the first surface. The opening may be smaller along one or more dimensions than the head contact chamber upon deployment such that the head contact chamber cannot enter the opening without engaging one or more portions of the airbag cushion defining the opening

Abstract: A side inflatable airbag assembly for a vehicle is disclosed. Inflatable airbag assemblies may provide protection for an occupant in a vehicle collision event. In a side collision event, or other event producing lateral movement of the occupant relative to the vehicle, the disclosed inflatable airbag assembly may receive and support the occupant during ride-down so as to prevent or minimize injury resulting from impact with a vehicle sidewall. An inflatable airbag cushion of the inflatable airbag assembly comprises a valve with an aperture and a vent flap that has a strong connection and a weak connection to the inflatable airbag cushion. The disclosed airbag may differentially support the occupant by providing varied degrees of support for the shoulder, pelvis, and torso, which may be particularly beneficial to an elderly occupant whose bones may be more susceptible to some injury types and modes as a result of age-incident health issues.

Abstract: A squib driver circuit for deployment of a deployable restraint in a vehicle. The safety restraint may have a minimum firing voltage. The voltage regulator may regulate the input voltage to be the minimum firing voltage at the input terminal. The squib driver circuit may be formed on a single chip. The squib driver circuit may include a high side driver and a low side driver. An input terminal for receiving an input voltage used to fire the deployable restraint. The high side driver may supply current from the input terminal to the deployable restraint. The low side driver may supply current from deployable restraint to the electrical ground.
