摘要： Valve for an airbag system for a motor vehicle and airbag system for a motor vehicle
The invention relates to a valve for an airbag system for a motor vehicle, having:



a housing (20) which extends along a longitudinal axis (21) and surrounds a cavity (22) having a taper (17) and surrounds a control chamber;
an electrically switchable pilot valve (15) which selectively seals or releases a pilot opening (6) of the control chamber (5);
a piston (3) which is arranged in the cavity (22) and can be displaced along the longitudinal axis (21) relative to the housing (20);
an equalization line (4, 18) which connects an inlet (1) of the valve (100) to the control chamber (5) for fluid communication, wherein:
a sealing seat (2) is formed at the taper (17) in order to block a gas flow from the inlet (1) to an outlet (14) of the valve (100) in a closed position, in which the piston (3) is in contact with the sealing seat (2), and to release said gas flow in further positions;
the control chamber (5) is arranged on a first side (24) of the piston (3) facing away from the sealing seat (2); and
the piston (3) has a first diameter on a side (23) facing the sealing seat (2) and a second diameter (26) on the first side (24), the first diameter (25) being less than the second diameter (26).

摘要： There is provided a system for improving safety of an occupant by an airbag, which can provide adaptive protection for occupants in different seat positions and different sitting postures. Further, there is provided a method for improving safety of an occupant by an airbag. Further, there is provided a computer-readable medium. The system for improving safety of an occupant by an airbag includes an in-vehicle observation system, an inflatable restraint system, a collision prediction system, and an integrated safety domain control unit. The integrated safety domain control unit formulates a deployment strategy based on data transmitted from the in-vehicle observation system, the inflatable restraint system, and the collision prediction system, to selectively inflate at least one airbag assembly and control an inflation volume for the airbag assembly to be inflated.

摘要： Airbag module mounted in connection with a steering wheel includes an inflator for generating gas and arranged on the steering wheel assembly, a conduit between the inflator and the interior of the airbag, and an aspirating structure arranged in connection with the conduit for enabling air from a passenger compartment to flow into the conduit and thus into the interior of the airbag. The airbag may be housed in a housing in a middle of the steering wheel. The aspirating structure may include one or more nozzles and/or one or more valves to allow for air flow from the passenger compartment into the conduit and prevent reverse flow. The inflator may include propellant distributed around an outer wall of the inflator.

摘要： Airbag inflator system includes an inflatable airbag, a housing and a gas generating system arranged in the housing for generating gas. The gas generating system provides variable amounts of gas to the airbag as a function of temperature. A nozzle may be arranged between the gas generating system and an interior of the airbag, the nozzle being varied as a function of temperature. The housing may be movably arranged relative to a fixed base and mounted to vary its relation to the base. To this end, elastic or temperature-deformable supports may be used to support the housing on the base. When the housing defines a chamber containing generated gas, the properties of a conduit between the chamber and the interior of the airbag can be varied as function of the pressure in the chamber.

摘要： An occupant sensing and crash behavior system for a motor vehicle determines the presence and location of an occupant to then control the deployment of supplemental restraint systems such as air bags or inflatable seat/shoulder belts. Crash anticipation and crash severity sensors provide additional inputs to the system to determine the behavior of the crash and the occupants therein. An infrared sensor emits a plurality of beams to determine the location and position of the occupant as does a proximity sensor located on the air bag door or the occupant seat. Occupant weight plus the presence and orientation of a child seat are considered. Seat belt control is provided to control the length of the seat belt during an impact or crash.

摘要： A method for controlling the filling of an airbag for a vehicle includes closing a valve of a gas generator for the airbag, this valve being connected to an interface to a gas sack of the airbag, after a main volume of a gas has flowed out of the gas generator, through the valve into the gas sack in a first gas mass flow, and opening the valve to direct a residual volume of gas out of the gas generator, through the valve into the gas sack in a second gas mass flow, the second gas mass flow being smaller than the first gas mass flow.
