  • Patent number: 12233805
    Abstract: A motor vehicle and a method secure a passenger in the motor vehicle in a collision. The motor vehicle has a seat including a seat body, which forms a seat surface, and a backrest connected to the seat body. An inertial force acting on the passenger in a collision is transmitted by a seatbelt arrangement to the backrest in such a manner that the latter pivots forwards relative to the seat body counter to the restoring effect of an elastic and/or plastic deformation of at least part of the backrest. A force which counteracts the pivoting-forwards action is generated by a force generator, and transmitted to the backrest, and/or the maximum pivoting path of the backrest is limited by a limiting device in that, when a predetermined reference acceleration is present, a deviation between a present pivoting path of the backrest and a predetermined reference pivoting path is minimized.

  • Patent number: 12221051
    Abstract: A steering wheel is disclosed enabling suppressing unnecessary rocking of the airbag module during airbag activation and thereby ensures prescribed deployment performance of the airbag cushion. In detail, the steering wheel is provided with a core metal having a boss part configured so as to be mountable on a steering shaft and an airbag module movably provided with respect to the core metal and having an airbag cushion that can be expanded and deployed. The stopper of the core metal is separated from the stopper contact part of the airbag module in a non-activated state of the airbag, and comes into contact with the stopper contact part due to movement or deformation of the airbag module caused by expansion and deployment of the airbag cushion during activation of the airbag.
