Airbag Module With an Adaptive Influencing Device

摘要

An airbag module having a first shell (10) forming a first gas chamber (GI), a first inflator for the first gas chamber (GI), an adaptive influencing device for influencing the ventilation or shape of the first gas chamber (GI), and an actuation unit (40) for the influencing device. The actuation device (40) has a second shell (44) forming a second gas chamber (G2), and a gas source. The state of the influencing device changing upon actuating the gas source. A tensioning element having a first end (62) is coupled to the adaptive influencing device or forms the device, and a second end (64) is coupled to the second shell (44) when the second gas chamber (G2) is not filled and is decoupled from the second shell (44) when the second gas chamber (G2) is filled.

主权项

1. An airbag module comprising:
a first shell enclosing a first gas compartment, a first inflator for filling the first gas compartment, an adaptive influencing device, for actively influencing the ventilation of the first gas compartment or the shape of the first shell,
an actuation unit for actuating the influencing device, the actuation unit having a second shell enclosing a second gas compartment, and a gas source for filling the second gas compartment, wherein the state of the influencing device changes when the second gas compartment is filled by the gas source, anda tensioning element having a first end coupled to the adaptive influencing device, or forms at least a portion of the adaptive influencing device, and having a second end is coupled to the second shell of the actuation device when the second gas compartment is not filled by the gas source, and is decoupled from the second shell when the second gas compartment is filled by the gas source.
