The invention relates to a load-bearing seatbelt retractor for a seat structure of a vehicle seat, the seatbelt retractor having two housing halves between which functional modules of the seatbelt retractor are disposed. One functional module is a belt reel having a winding axis. The two housing halves form two mutually parallel receptacles in the seatbelt retractor, which are oriented perpendicular to the winding axis. Two seat bars can be inserted into the receptacles. The two housing halves are in contact at least on two contact lines above and below the functional modules with respect to an insertion direction of the receptacles. The lower contact line splits open on both sides along the winding axis such that respective intermediate spaces open toward the receptacles are formed.

The present invention relates to a belt retractor comprising a belt shaft (), which is mounted rotatably in a frame () and on which a safety belt can be wound, and a force-limiting unit () which, when activated, enables a rotational movement of the belt shaft () in the extension direction of the safety belt, wherein the force-limiting unit () comprises an electric motor () and a first blocking device, and the first blocking device is configured to release and again block, in a manner actuated by the activation of the electric motor (), a rotational movement of the belt shaft () in the extension direction in a repeating sequence.

Belt retractor

A belt retractor comprising a belt reel rotatably mounted in a frame securable to a vehicle and on which a seatbelt can be wound, and a blocking device arranged on a mechanical side of the belt reel and which blocks the belt reel when a specified seatbelt pull-out acceleration and/or a vehicle deceleration is exceeded, activating the blocking device in the pull-out direction of the seatbelt, and an electric motor for rotating the belt reel, and a gearing mechanism which transmits the rotational movement from the electric motor to the belt reel, wherein the electric motor and gearing mechanism are arranged coaxial to the rotational axis of the belt reel and in series relative to the belt reel; and a transfer rod is provided arranged coaxial to the rotational axis of the belt reel and in series with the belt reel.

The present invention relates to a belt retractor comprising a belt shaft which is rotatably mounted in a housing and onto which a safety belt can be wound, the housing being able to be fastened to the vehicle, and an electric motor for driving the belt shaft to move rotationally, and a gear mechanism transmitting the rotational movement from the electric motor to the belt shaft, wherein the gear mechanism can be driven as an assembly in a first force-transmission path to drive the belt shaft with a first torque, and the gear mechanism can be driven to drive the belt shaft with a second torque, by shifting a speed-controlled and/or torque-controlled coupling, whereby a second force-transmission path is opened, wherein the coupling has at least one coupling element which is spring-loaded by a spring into engagement in a first part of the gear mechanism.

A seat-belt retractor comprising a seat-belt spindle, on which a seat-belt can be wound and which is rotatably mounted in a housing that can be fixedly secured to the vehicle, an electric motor for driving the seat-belt spindle in a rotational motion, and a gear mechanism that transmits the rotational motion from the electric motor to the seat-belt spindle, where a first blocking device is provided, which, when activated, blocks at least one of the parts of the gear mechanism, thereby activating the gear mechanism; and the first blocking device can be activated by a signal-controlled actuator, the actuator, in a second function, activating a second blocking device when a pre-defined feed-out acceleration of the seat-belt, or a pre-defined vehicle deceleration is exceeded.
