The multi-chamber front passenger airbag technology in the all-new 2021 Acura TLX sport sedan has been awarded as a 2020 “Best of What’s New” for 2020 by Popular Science and was distinguished as their “Grand Award” winner among all of the year’s automotive entrants.
Representing a major leap forward in airbag design, it is intended to address the recently recognized issue of severe brain trauma associated with angled frontal collisions.
The all-new Acura MDX three-row luxury SUV, set to go on sale early next year, will also feature this award-winning technology as standard equipment.
The new airbag is designed to help reduce head and neck injuries by better controlling the front passenger’s head in certain types of crashes. The airbag can better manage lateral collision forces that may cause an occupant’s head to rotate severely at high velocity, or to slide off a conventional passenger airbag, increasing the chance of serious injury.
Compared to a single inflatable chamber of conventional airbag systems, the new passenger airbag consists of four major components: three inflated compartments (a center chamber and two outward-projecting side chambers that create a wide base across the dash) and an uninflated “sail panel” that stretches between the two side chambers.
The “sail panel” is designed to initially catch and decelerate the occupant’s head with less force prior to contacting the lower chamber, while directing it inward between the two inflated chambers to cradle and help protect the front seat passenger’s head.
Co-developed by Honda R&D Americas and safety systems supplier Autoliv, this new airbag design is now being offered to other automakers to enhance the safety performance of their future products.
