Abstract: A leak-sealing device for sealing a leak in a container, a tank and/or a pipe includes a housing-type carrier unit, at least one expandable sealing member provided on an end region of the carrier unit, which does not expand, or only a little, in the storage position thereof, and at least one fluid connection and/or at least one fluid-release unit which is coupled to the carrier unit in such a way that, during the supply of fluid, the leak-sealing member is at least partially filled and expanded with the fluid in the sealing position thereof by means of a fluid supply. A method for sealing a leak using the leak-sealing device and to a system including the leak-sealing device and a fluid-supply device utilizes a release unit for fluid release.

Abstract: A motor vehicle steering shaft assembly having two complementary steering shaft pieces adapted to be connected to the vehicle steering gear and steering wheel, respectively. Each shaft piece has an end portion arranged in adjacent, overlapping relationship with the end portion of the other shaft piece. The two shaft pieces are connected by at least two independent, torque-transmitting plug connections which are axially spaced relative to each other along the overlapping end portions. Each of the plug connections includes projections or "plugs," attached and extending parallel to one of the shaft pieces, and corresponding receptacles, adapted to receive the projections, attached to the other shaft piece. As a result of this construction the two shaft pieces of the steering shaft assembly may be disconnected upon application of a predetermined axial force, but the steering shaft assembly will not bend upon application of a transverse force thereto.

Abstract: A steering wheel is designed to be attached to a steering column by means of a deformation member to enable the steering wheel to tilt with respect to the axis of the steering column upon impact by the driver. The deformation member is a flat plate with lines of reduced strength preferably in the form of spirals extending from the center of the hub.
