  • Vehicle side door
    Patent number: 4786100
    Abstract: A vehicle door whose inside is deformable under energy dissipation. The inside is thereby subdivided into different sections matched in its rigidity to the individual body regions of the passenger. Furthermore, the rigidity can increase toward the rear door frame so that taller vehicle passengers find altogether a more rigid door inside when the seat is displaced toward the rear. The vehicle door is to reduce the injury risks in case of a lateral impact.
