Systems for active coupling of airbags
An airbag deployment system includes a helmet, a torso protection assembly, and an airbag assembly. The airbag assembly is coupled to one of the helmet and the torso protection assembly and includes an airbag, an inflation device configured to inflate the airbag, and a first coupling device.
