Vehicle passenger protection system has device that after certain time has elapsed after inflation of gas bag, reduces tension working on tension device

摘要

A vehicle passenger protection system has an inflatable gas bag (12), especially a side gas bag, and a tension strip (24) that is tensioned in the case of the gas bag being inflated. The protection system has a device (26-626) that after a certain time has elapsed after the inflation of the gas bag, reduces the tension working on the tension device. The tension strip is connected directly with the device. The device contains a medium with a high viscosity and a medium with a variable viscosity. The medium is an electro-rheological or magneto-rheological fluid. The medium with a high viscosity is contained in a bag which tears at a certain tension.
