Abstract
A safety belt reeling device with inclination compensation is connected to a vehicle seat, wherein the part of the vehicle seat to which the safety belt reeling device is connected is inclination-adjustable relative to the axis oriented to the center of the earth, and has a vehicle-sensitive acceleration sensor to be oriented in a nominal position to the center of the earth. A pendulum mass, pivotable about a pivot point, acts on the acceleration sensor for returning the acceleration sensor into the nominal position when inclination changes occurs. A first inertia mass in the form of a first instable compensation pendulum sensitive to acceleration forces is provided. The first compensation pendulum is pivotable about the pivot point of the pendulum mass. A first locking member is coupled to the first pendulum mass and the compensation pendulum. A stationary blocking toothing is provided. When horizontal acceleration forces occur, the pendulum mass and the first compensation pendulum pivot in opposite directions and force the first locking member into engagement with the blocking toothing for locking the pendulum mass relative to the safety belt reeling device.
