Abstract
A frontal airbag (10) having an outer skin (12) enclosing a gas space (G). The outer skin (12) forming an impact area (14) in front a vehicle occupant (P) and extends horizontally in a first direction (Y) and in a second perpendicular direction (Z′) when the airbag (10) is fully deployed. A first tether (20) extends in the first direction (Y) from a first end (21) connected to the impact area (14) at a first connection (25) to a second end (22) connected to the impact area (14) at a second connection (26). The first connection (25) extending in the second direction (Z′) from a lower end to an upper end and the second connection (24) extending in the second direction (Z′) from a lower end to an upper end, such that an intermediate impact area section (14c) is spanned by the first tether (20). The first tether (20) is under tension when the outer skin (12) is fully deployed such that the tension in the intermediate section (14c) of the impact area (14) is reduced relative to impact area sections (14a, 14b) next to the intermediate section (14c).
