Abstract
The present invention can include an automobile having a multi-stage inflation system. The multi-stage inflation system can include an engine control unit, a multi-stage inflation unit, a curtain airbag, a curtain airbag pressure indicator, and/or a rollover side impact detection unit. The rollover side impact detection unit can detect when a side impact or a rollover occurs to the automobile. When the rollover or the side impact is detected, the engine control unit can instruct the multi-stage inflation unit to deploy and inflate the curtain airbag in multiple stages. The multi-stage inflation unit can include a pyrotechnic inflation unit with multiple compartments. At each of the stages, a different one of the multiple compartments can be activated to substantially inflate the curtain airbag. The multi-stage inflation unit can also optionally include a cold gas inflation unit to supplement the pyrotechnic inflation unit.
