A method is provided for producing a decorative part that has a closed cross-section having an external visible side and that has at least two support parts to be connected along a connecting joint. The support parts are held spaced at a distance from one another such that a gap is formed between the edges of the support parts which adjoin one another at the connecting joint. The support parts are inserted in at least two halves of a molding tool. A reaction plastic is injected into the molding tool, such that the reaction plastic penetrates the gap. The support parts are moved toward each other such that the gap closes while the reaction plastic is still liquid. The support parts are fixed against each other in this position at least until the plastic has sufficiently cured so as to form a bond seam in the connecting joint.

A shaft, in particular a drive shaft, for transferring torques, includes a basic member made of an elastic first material, and connecting pieces shaped at their ends for being received by the basic member and prevented by positive engagement from rotating and displacing axially relative to the basic member. The connecting pieces are made of a second material which is inelastic or less-elastic than the first material or. The first and second materials are plastics which are crosslinked with one another at interfaces of the basic member and the connecting parts. The shaft is reliably functional while having a compact design.

Steering wheel having a steering wheel rim which is hollow at least in some places and has ventilation openings for stabilizing the temperature of the steering rim. In the region of the at least one cavity, the steering wheel rim has a holder for fixing a fan module which sucks in environmental air and passes it into the cavity.

A steering column arrangement has an interior steering column tube which can be axially and telescopically adjusted by a spindle drive relative to an exterior steering column tube. A threaded spindle of the spindle drive is disposed by way of energy-absorbing bearing blocks. The longitudinally extending adjusting member is provided with a desired buckling point. At the level of the desired buckling point, a supporting bow is provided which is stationarily arranged on the exterior steering column tube, reaches at least partially over the desired buckling point and is designed to be plastically deformable.

A steering column arrangement has an adjusting spindle of a spindle drive for the axial adjustment of the interior steering column tube relative to the exterior steering column tube which is fixed by a holder on the interior steering column tube. The holder is a ring-shaped collar which, by way of a ring arrangement positioned between the outer jacket of the interior steering column tube and the inner circumference of the collar, is axially form-lockingly and frictionally engaged in the circumferential direction fixed on the interior steering column tube.

An air bag for a motor vehicle has catch straps which are located on the inside and by means of which an upper bag surface directed towards a vehicle occupant and a lower-lying bag surface of the unfolded air bag having an opening for a gas generator are held against one another along the length of the catch straps. By one end, the catch straps integrally adjoin a flat connecting part via which they are fixed on the upper bag surface by means of at least one connecting seam which runs around said connecting part and lies nearest to the catch straps, the connecting seam being disposed perpendicular to the pulling direction of said catch strap in the region of each catch-strap connection at least over the greatest part of the connection width.

A joint is disclosed for the swivel bearing of a casing tube of an inclination-adjustable steering column on a casing tube suspension, having a joint head which is held between laterally surrounding fork legs, coaxial passage bores in the surrounding fork legs from which a longitudinal section of a bearing axle projects into an opposite fitted seat of the joint head, and two bearing bushes which surround the projecting longitudinal section of their bearing axle and which are conically constructed on their outer circumference and engage in their associated, fittingly conical fitted seat. An axial loading of the bearing bushes tapering toward one another is by way of a screwed advance of their bearing axle by means of which the bearing bushes are pressed without play into their fitted seat. In order to permit a lower-cost manufacturing of the joint, both fitted seats of the joint head are arranged in the end area of a cylindrical bore which is widened by means of a chamfer to form a fitted seat, and the bearing bushes have a basic cylindrical shape and engage by means of a conically slanted end area into the assigned fitted seat of their bore, their end area being constructed to be radially flexible.

Collision-protection devices for vehicle passengers, are disclosed which include a gas cushion which is connected to a gas generator and inflates under sensor control in the event of an accident and hence protects the body of a vehicle passenger from a collision causing injury, e.g., against the instrument panel or windscreen. The gas cushion has, in this instance, one or more escape openings. According to the invention, the escape opening points towards an open cover flap when the gas cushion is inflated, which cover flap, in the closed state, covers the folded-up gas cushion. Only once a predetermined pressure has been exceeded does the cover flap free the escape opening to enable gas to be discharged in an escape flow distributed over an area of the gas cushion surface.

According, two casing parts is disclosed for a spiral cable for connecting electrical line terminals between a stationary vehicle steering column and a rotatable steering wheel. One of the two casing parts has an annular space for the spiral cable which is open towards an axial face and the other casing part is in the form of a plate for covering the annular space. It is thus possible to arrange the two casing parts at an axial distance from one another and thus to prevent the two parts from rubbing against one another.

A motor vehicle steering wheel has flat steel deformable spokes which connect a steering-wheel rim to a hub to be mounted on a steering shaft. The associated free ends of the spokes are cast into the cast hub, and each spoke has in the cast-in area a passage bore which extends in the axial direction of the steering wheel and penetrated by the hub material during the casting process. In order to achieve an increase in rigidity in the hub/spokes connecting area, the passage bore is arranged directly adjacent to the entry area of the spoke into the hub, forming a rolling step, such that in this area a tension-rod connection is formed between the hub material located above and below the spoke.

A shifting arrangement for the shifting between a single-axle standard drive and an all-wheel drive having a first clutch for the locking of a central differential gear and a second clutch for the connecting and disconnecting of one vehicle axle actuated by first and second pressure medium control element respectively against the force of a spring having first and second shift valve respectively controlled by an electronic control unit, to either supply working pressure or relieve from pressure respective control elements. The improvement including a hydraulic identifying valve for bringing the control elements into a mutual interaction. The identifying valve operates, as a function of the working pressure of at least one of the control elements and exclusively during the simultaneous controlling of both shift valves, in such a way that the clutch torque at both clutches increases and decreases approximately to the same extent. As a result, when shifting into a shift step with a balanced all-wheel drive from standard drive, a shifting can first take place for a short time into an intermediate step with a longitudinally locked all-wheel drive for securing the driving stability.

An ignition lock unit with a disassembly which can be cancelled only by means of an associated key rotated into a predetermined position and with a coupling connected to cable ends which is adapted to be mounted over the coordinated contact pins of the ignition starter switch part of the ignition lock unit. The coupling includes a contact carrier plate with a centrally arranged aperture for a locking rod extending out of the ignition starter switch, whereby the latter during the assembly and disassembly of the coupling, passes through this aperture when a corresponding position is reached by means of the key. In every other position of the key or with a removed key, the free end of the locking rod engages the aperture hook-shaped from behind.
