Definitions

  • the present disclosure relates to a method for occupant protection, an occupant protection system, and a motor vehicle with such an occupant protection system.
  • the existing side airbag restraint systems are developed for specific sitting positions and postures, the size and mounting position of airbags are fixed, which cannot adapt to the increasingly diversified sitting postures arising with the development of intelligent vehicles.
  • the current side curtain airbags cannot cover the area below the lower edge of the car window, and as a result, after the occupant adjusts the inclination of the seat by a large angle, the protective effect of curtain airbags will be greatly reduced or the curtain airbags cannot provide any effective protection; in addition, when the occupant lies down, the change of his/her sitting position will cause the protection of seat-side airbags to displace away from the critical body parts of the occupant that are vulnerable to injuries.
  • the half-lying posture is more common in the co-driver’s seat but is less common in the driver’s seat, since the driver needs to drive and operate.
  • the hands and feet of drivers will be gradually freed, so a restraint system that is applicable to both traditional and future sitting postures becomes necessary. Therefore, a new challenge is posed for occupant protection to adapt to different sitting postures.
  • a method for occupant protection of a motor vehicle comprising the following steps:
  • S1 acquiring body characteristic information of an occupant and seat position information
  • This provides the advantage that an optimal airbag position for occupant protection can be obtained via adjustments made based on the body type characteristics of the occupant and the current position and state of the vehicle seat, such as an upright sitting posture, a lying-down or half-lying position of the co-driver’s seat, or a lying-down or half-lying position of the driver’s seat during automated driving.
  • the method further comprises:
  • the body characteristic information includes height, weight, body size, gender and/or age of the occupant.
  • the seat position information includes the position, the height of a cushion and/or the inclination of a backrest of a vehicle seat.
