Abstract: A safety belt reeling device with a belt-sensitive control system, for locking the reeling shaft when safety belt removal occurs at a rate above a preset limit, has a reeling shaft and a safety belt fastened thereto. The reeling shaft is rotatable for winding and unwinding the safety belt. A vehicle-sensitive control system locks the reeling shaft when horizontally acting vehicle acceleration forces are too great. The vehicle-sensitive control system has a control disk with outer toothing and a locking lever cooperating with the outer toothing. The reeling shaft is locked when the locking lever engages the outer toothing and released when the locking lever disengages the outer toothing. The vehicle-sensitive control system has a first sensor activating the locking lever for engaging the outer toothing when a first preset threshold value, defined by government standards, for horizontally acting vehicle acceleration forces is surpassed.

Abstract: An inclination-compensatable safety belt reeling device 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 an axis extending to the center of the earth, has a vehicle-sensitive acceleration sensor to be oriented in a nominal position to the center of the earth. A pendulum device with a pendulum mass acts on the acceleration sensor for returning the acceleration sensor into the nominal position when an inclination change occurs. An inertia mass in the form of a deceleration mass sensitive to horizontal acceleration forces is provided. A stationary blocking toothing is also provided. The pendulum mass has laterally projecting arms with guide projections extending in a direction of movement of the deceleration mass. The deceleration mass is positioned with slotted holes on the guide projections so as to be slidingly linearly guided.

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.

Abstract: In a back rest for a vehicle seat, the upholstery support is provided at least in one upper corner area in its front side with an opening to form a receptacle for a belt retraction device, which receptacle is open toward the front and closed at the rear by a back wall lying behind and spaced from the front side. An upper and a lower wall, which form the top and bottom of the receptacle, are connected with the front wall and/or the back wall and are spaced from each other so as to allow the receptacle to receive the belt retraction device without play. Form-fitting, overlapping restraining elements on the upper wall and the facing upper side of the belt retraction device, as well as on the back wall and the facing back side of the belt retraction device, together with a connecting element that engages the underside of the belt retraction device, secure the retraction device against being moved out of the receptacle.
