  • Belt retractor with a switchable force-limiting device for a seatbelt of a motor vehicle
    Patent number: 9248803
    Abstract: A seat belt retractor with a switchable load limiting device for a safety belt of a motor vehicle with a belt shaft and a locking device which upon actuation locks the belt shaft in the belt extraction direction. The load limiting device is located in the force flow between the belt shaft and the locking device between the load limiting levels. A switching device is used for switching the load limiting device. The switching device includes a gas generator for releasing a gas flow into a pressure chamber and an expandable hollow pot which can be driven by the gas flow. The expandable hollow pot is attached to the gas generator in a gas-proof manner and forms the pressure chamber.
