Abstract: The invention relates to a device for unfolding a rolled-up elongate hollow member having: at least one elongate hollow member which has two elongate shell member halves, and an unfolding mechanism which has a fixed base structure and a winding core which is rotatably supported on the base structure and on which the at least one elongate hollow member in a first state is rolled up and compressed and which by rotating moves and unfolds the elongate hollow member from the first state into an unrolled and unfolded second state so that an elongate hollow space is formed between the two shell member halves of the at least one elongate hollow member, wherein the at least one elongate hollow member has as a first end a hollow member root, via which the elongate hollow member is secured to the rotatably supported winding core, wherein the first shell member half of the at least one elongate hollow member is secured in the region of the hollow member root to the rotatably supported winding core, and the unfolding m

Abstract: The invention relates to a brake device for producing a brake torque counter to a torque acting on a rotatably supported member, wherein the brake device has: at least one toothed brake ring which is mechanically actively connected to the rotatably supported or supportable member, a plurality of bending-resistant brake levers which each have at a first lever end at least one stop which engages in the tooth arrangement of the brake ring and which are each rotatably supported on a second lever end opposite the first lever end, wherein each brake lever is connected to a force element for applying a brake force in such a manner that, as a result of the brake force via the stop of the respective brake lever which is in engagement with the tooth arrangement of the brake ring, a brake torque is produced on the brake ring tangentially counter to the active direction of the torque in order to apply a brake torque to the rotatably supported or supportable member, wherein the brake levers are arranged with respect to
