In a side impact, the second most common type of accident after head-on collisions, side and head airbags come into play. Head airbags in particular reduce the risk of head injuries and supplement the action of side airbags.
Head airbags, also known as window bags, are located along the roof. The head airbag is a flat airbag that when unfolded covers the area of the side windows from the A to the C pillar, thus offering additional, special protection for the head.
