Vehicle seat, method for reducing the introduction of forces or momentum and use of a belt mounting fixture

The vehicle seat (1) has a seat part, a backrest (3) and a belt restraint device that is integrated at the vehicle seat. An attachment (8) has a crash element (13) with a deformation region for reduction of kinetic energy during accidental activation of the belt restraint device. The crash element has a sheet-type base body (16,17) with a sheet metal rib and two distant conditioning levels. Independent claims are also included for the following: (1) a method for reducing a force or torque initiation at an adjustment between a seat part and a backrest of a vehicle seat; and (2) an application of belt suspension mounting of a vehicle seat belt restraint device for shortening a lever path.
