A device for activating a passenger protection unit for a vehicle. The device includes a fuel element chamber having at least one fuel element, which is designed to generate a hot gas for activating the passenger protection unit by combustion, the fuel element chamber having an outlet opening for releasing the hot gas into the passenger protection unit, and the pressure container being designed to store a pressurized cold gas, the pressure container having at least one opening for the controlled release of the cold gas into the fuel element chamber.

1. A device for activating a passenger protection unit for a vehicle, the device comprising: a fuel element chamber including at least one fuel element, which is designed to generate a hot gas for activating the passenger protection unit by combustion, the fuel element chamber having an outlet opening that releases the hot gas into the passenger protection unit;a pressure container storing a pressurized cold gas, the pressure container having at least one opening for a controlled release of the cold gas into the fuel element chamber;a valve for controlling the release of the cold gas through the at least one opening of the pressure container and into the fuel element chamber; anda control unit that receives a collision signal in response to a collision involving the vehicle, wherein, in response to the collision signal, the control unit generates a valve control signal to at least partially open the valve in response to the collision signal and transmits the valve control signal to the valve. 2. The device as recited in claim 1, wherein the pressure container is situated within the fuel element chamber. 3. The device as recited in claim 1, wherein the valve is situated at least one of: i) outside the pressure container, and ii) within the fuel element chamber. 4. The device as recited in claim 1, wherein the valve is designed to effectuate in a first valve position that a piston of the device, which is movably situated in relation to the at least one opening of the pressure container, unblocks the opening to allow the cold gas to be released into the fuel element chamber, and to effectuate in a second valve position that the piston closes the opening to suppress the release of the cold gas into the fuel element chamber. 5. The device as recited in claim 1, wherein the fuel element chamber and the pressure container each have a ring shape. 6. The device as recited in claim 1, wherein the fuel element chamber and the pressure container each have a cylindrical design, and the opening is situated on an end face of the pressure container, and the outlet opening is situated on an end face of the fuel element chamber. 7. The device as recited in claim 1, wherein: the control unit generates an ignition signal to ignite the at least one fuel element in response to the collision signal, anda time at which the control unit generates the ignition signal is different than a time at which the control unit generates the valve control signal. 8. The device as recited in claim 7, wherein the time at which the control unit generates the valve control signal occurs after than the time at which the control unit generates the ignition signal. 9. A passenger protection system for a vehicle, the passenger protection system comprising: a device for activating a passenger protection unit for a vehicle, the device including: a fuel element chamber including at least one fuel element, which is designed to generate a hot gas for activating the passenger protection unit by combustion, the fuel element chamber having an outlet opening that releases hot gas into the passenger protection unit,a pressure container storing a pressurized cold gas, the pressure container having at least one opening for a controlled release of the cold gas into the fuel element chamber;a valve for controlling the release of the cold gas through the at least one opening of the pressure container and into the fuel element chamber; anda control unit that receives a collision signal in response to a collision involvingthe vehicle, wherein, in response to the collision signal, the control unit generates a valve control signal to at least partially open the valve in response to the collision signal and transmits the valve control signal to the valve, wherein the passenger protection unit is connected to the device and is activated with the aid of at least one of the hot gas and the cold gas, generated in the device. 10. The passenger protection system as recited in claim 9, wherein: the control unit generates an ignition signal to ignite the at least one fuel element in response to the collision signal, anda time at which the control unit generates the ignition signal is different than a time at which the control unit generates the valve control signal. 11. The passenger protection system as recited in claim 10, wherein the time at which the control unit generates the valve control signal occurs after the time at which the control unit generates the ignition signal. 12. A method for activating a passenger protection unit for a vehicle, the method comprising: igniting at least one fuel element situated in a fuel element chamber to generate a hot gas by combustion of the fuel element and release the hot gas through an outlet opening in the fuel element chamber into the passenger protection unit to activate the passenger protection unit; andcontrolling a valve to from a pressure container through at least one opening of the pressure container to the fuel element chamber to further activate the passenger protection unit, wherein the controlling of the valve is performed in response to a valve control signal generated and transmitted by a control unit in response to a collision signal generated in response to a collision involving the vehicle. 13. The method as recited in claim 12, wherein: the control unit generates an ignition signal to ignite the at least one fuel element in response to the collision signal, anda time at which the control unit generates the ignition signal is different than a time at which the control unit generates the valve control signal. 14. The method as recited in claim 13, wherein the time at which the control unit generates the valve control signal occurs after the time at which the control unit generates the ignition signal. 15. A method for manufacturing a device for activating a passenger protection unit for a vehicle, the method comprising: providing a fuel element chamber, at least one fuel element and a pressure container, the fuel element being designed to generate a hot gas for activating the passenger protection unit by combustion, the fuel element chamber having an outlet opening for releasing the hot gas into the passenger protection unit, and the pressure container being designed to store a pressurized cold gas and having at least one opening for a controlled release of the cold gas into the fuel element chamber;situating the at least one fuel element and the pressure container in the fuel element chamber;providing a valve for controlling the release of the cold gas through the at least one opening of the pressure container and into the fuel element chamber; andproviding a control unit that generates and transmits a valve control signal in response to a collision signal that is generated in response to a collision involving the vehicle, wherein the valve at least partially opens in response to the valve control signal. 16. The method as recited in claim 15, wherein: the control unit generates an ignition signal to ignite the at least one fuel element in response to the collision signal, anda time at which the control unit generates the ignition signal is different than a time at which the control unit generates the valve control signal. 17. The method as recited in claim 16, wherein the time at which the control unit generates the valve control signal occurs after the time at which the control unit generates the ignition signal.
