1. A method for securing a passenger in a motor vehicle in a collision, the motor vehicle including a seat which comprises a seat body forming a seat surface, and a backrest connected to the seat body, wherein an inertial force acting on the passenger in the seat in a collision is transmitted by a seatbelt arrangement to the backrest in such a manner that the backrest pivots forwards relative to the seat body counter to a restoring effect of an elastic and/or plastic deformation of at least part of the backrest, the method comprising:
generating, by a force generator, a force to counteract the pivoting-forwards action of the backrest, and transmitting the force to the backrest and/or limiting, by a limiting device, a maximum pivoting path of the backrest; and
minimizing, when a predetermined reference acceleration is present, a deviation between an actual pivoting path of the backrest and a predetermined reference pivoting path.
