US Patent 11975674 Airbag systems for autonomous vehicles

Aspects of the disclosure provide for airbag systems suited for autonomous vehicles. Such an airbag system may include a first chamber, a second chamber, a dual-stage inflator, an orifice blocker mechanism and a control module. The dual-stage inflator may be in fluid communication with the first chamber via a first orifice and in fluid communication with the second chamber via a second orifice. The orifice blocker mechanism may be configured to block and unblock gas flow from the second orifice to the second chamber. The control module may be configured to activate the dual-stage inflator in order to inflate one or both of the first chamber and the second chamber with gas based on a position of the orifice blocker mechanism relative to the second orifice.
