  • the protective element is such that, for at least a limited period of time, it withstands the frictional forces occurring between it and the roadway after impacting the vehicle.
  • the protective element thus protects, in particular in the case of lateral falls of the seat against injuries due to the (in particular first) impact with the road and / or from abrasions when sliding on the road.
  • the inflated protective element lays like a protective carpet between the falling seats and the roadway.
  • the protective element (in particular its thickness), however, is not necessarily designed to counteract injuries due to bruises.
  • the protective element "withstands" the frictional forces does not necessarily mean that it is not damaged by the action of the frictional forces, however, at least for a certain period of time after inflation no damage occurs which leads to a significant escape of gas from the protective element.
  • At least a portion of the protective element is such that its resistance to the frictional forces occurring upon contact with the roadway is at least approximately equal to a position of a gas bag material of a passenger car airbag or higher than that of a layer of such a gas bag material.
