METHOD FOR SECURING A PASSENGER IN A MOTOR VEHICLE, AND MOTOR VEHICLE

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.
