A hybrid airbag inflator includes a pyrotechnic booster gas generant disposed in a booster combustion chamber and a pyrotechnic main gas generant disposed in a main combustion chamber. The hybrid airbag inflator also includes an initiator and a pressurized gas. The pyrotechnic booster gas generant and the pyrotechnic main gas generant are the same pyrotechnic composition but take different physical forms. The initiator deploys into the booster combustion chamber to ignite the pyrotechnic booster gas generant which in turn ignites the pyrotechnic main gas generant. The pressurized gas is in fluid communication with both the booster combustion chamber and the main combustion chamber prior to deploying the initiator, such that the pyrotechnic booster gas generant in the booster combustion chamber is under pressure before the initiator deploys.

An energy absorbing seatbelt assembly according to various implementations comprises a frame, a first spool portion, and a separately formed second spool portion, wherein both spool portions are rotatably coupled to the frame. A torsion bar comprises a first end coupled to the first spool portion and a second end coupled to the second spool portion, wherein both ends of the torsion bar rotate in opposite directions as the first and second spool portions rotate relative to the frame. The energy absorbing seatbelt assembly further comprises a cable with a first end coupled to the first spool portion, a second end coupled to the second spool portion, and a middle portion coupled to a seatbelt buckle or anchor, the middle portion of the cable extending between the first end of the cable and the second end of the cable.

Described and disclosed herein are systems, methods and devices of in-vehicle radar comprised of an antenna array having a plurality of emitters and receivers, wherein the emitters and receivers are configured such that the divergence of the radar beams is concentrated on specific regions of interest, or to spread the divergence in a way to make the detection region uniform within the vehicle.

In one embodiment, a system of detecting seat belt operation in a vehicle includes at least one light source configured to emit a predetermined wavelength of light onto structures within the vehicle, wherein at least one of the structures is a passenger seat belt assembly having a pattern that reflects the predetermined wavelength at a preferred luminance. At least one 3-D time of flight camera is positioned in the vehicle to receive reflected light from the structures in the vehicle and provide images of the structures that distinguish the preferred luminance of the pattern from other structures in the vehicle. A computer processor connected to computer memory and the camera includes computer readable instructions causing the processor to reconstruct 3-D information in regard to respective images of the structures and calculate a depth measurement of the distance of the reflective pattern on the passenger seat belt assembly from the camera.

A battery status detection system for an electric vehicle battery pack includes a tube coupled at one end to a valve and at the other end to the battery pack. The system further includes a gas analysis chamber which is coupled to the valve and includes a gas analysis sensor. A pump is coupled to the gas analysis chamber and configured to move gas through the tube, the valve, and the gas analysis chamber. A controller includes a processor which is configured to start the pump, open the valve, and analyze the gas moved by the pump using the gas analysis sensor. By analyzing the composition of the gas, the battery status detection system is able to detect and/or predict dangerous conditions in the battery pack.

A vehicle cabin gas sensing system includes a tube having a first end and a second end. The first end is coupled to a valve and the second end is disposed within a vehicle cabin. The system further includes a gas analysis chamber which is coupled to the valve and includes a gas analysis sensor. A pump is coupled to the gas analysis chamber and configured to move gas through the tube, the valve, and the gas analysis chamber. A controller includes a processor which is configured to start the pump, open the valve, and analyze the gas moved by the pump using the gas analysis sensor. By analyzing the composition of the gas, the vehicle cabin has sensing system is able to detect undesirable conditions in the vehicle cabin.

An inflator comprises a housing having a base, a wall extending from the base, and an inner volume at least partially defined by the base and the wall. A pyrotechnic gas generant material is disposed within the inner volume and an intumescent material is also disposed within the inner volume. The base may have an inner surface and an outer surface, and the wall may also have an inner surface and an outer surface. The inner surface of the base and the inner surface of the wall face the inner volume. The intumescent material may be in contact with the inner surface of the base and/or the inner surface of the wall. Alternatively, the intumescent material may be disposed outside the inner volume and may be in contact with the outer surface of the base and/or the outer surface of the wall. An airbag module may include the inflator.

A vehicle hood lifter and airbag assembly according to various implementations includes a housing having a first end, a second end, and a wall extending from the first end to the second end. The wall comprises an inner surface and an outer surface and defines a gas exit orifice disposed between the first end and the second end. The vehicle hood lifter and airbag assembly further includes a piston assembly which is slidably engaged with the inner surface. The vehicle hood lifter and airbag assembly further includes a pressurized gas disposed within a gas chamber. Upon actuation, the pressurized gas is released from the gas chamber causing the piston assembly to move from adjacent the first end to adjacent the second end. The pressurized gas then exits the housing through the gas exit orifice and flows into an airbag which is coupled to the outer surface.

A system for controlling air quality in a vehicle cabin includes at least one mechanical filtering device receiving unfiltered air and collecting particulate matter from the unfiltered air. Air flow downstream from the mechanical filtering device is a first filtered air flow. At least one ultraviolet (UV) light source is positioned within the vehicle between the at least one mechanical filtering device and the vehicle cabin, wherein the UV light source directs UV light into the first filtered air flow.

A switch assembly that provides haptic feedback includes a printed circuit board (PCB) having a first planar surface that faces in a first direction and a second planar surface that faces in a second direction, the second direction being opposite from the first direction, a touch plate having a first surface that faces in the first direction and a second surface that faces in the second direction, wherein the first surface of the touch plate is proximate the second planar surface of the PCB, and a haptic exciter that has a conductive coil of wire having a hollow inner core and a magnet that is at least partially disposed within the hollow inner core of the coil of wire such that the magnet alternatively moves in the first and second directions as an alternating current passes through the conductive coil of wire.
