An adjustable telescopic steering column for motor vehicles has at least one longitudinally adjustable telescopic section which is held in an adjusted position by a locking device. In the event of a crash, the telescopic section is acted upon by an additional holding force by way of a locking part. The locking part is a component which operates independently of the locking device for the adjusted position and, in the operative position, is applied with a frictional connection to the longitudinally adjustable telescopic section.

The invention relates to an air bag for occupant restraint systems of motor vehicles, which air bag is automatically inflated by means of a gas generator in the event of an accident. In order subsequently to allow slackening of the air bag, a kidney-shaped or crescent shaped zone of the air bag cover, which is arranged at a greater distance from and approximately centrally to a central region of the air bag facing the occupant, is produced from gas-permeable fabric. Due to the specified shape and arrangement of this zone, the necessary load-bearing capacity of the air bag remains guaranteed.

A safety arrangement in the leg room of a motor vehicle has a strut of a suspension for the tube of a safety steering column hanging down from a cross member into the leg room. A crash-caused bending of the strut is connected with a raising of the forward steering column tube end. A pedal assembly is arranged laterally next to the strut on a front wall of the vehicle body bounding the leg room in the front. In order to prevent an erection of the steering column tube caused by a shock impulse in the event of a crash of the motor vehicle with a rearward displacement of the pedal assembly, at least one laterally supporting deflecting device is arranged on the pedal assembly and/or on the strut, by way of which the pedal assembly is guided past the strut.

An adjusting arrangement for adjusting the slope of a swivellably connected casing tube of a steering spindle of a motor vehicle comprises a supporting device which is disposed on the vehicle body and with which the casing tube is connected by way of a spindle drive by means of which the casing tube can be adjusted with respect to the vehicle body. At least one steering lever having two mutually spaced, parallel swivel shafts acts between the casing tube and the vehicle body, of which one swivel shaft is assigned to the supporting device and the other swivel shaft forms a component of the spindle drive, and the spindle drive takes over the function of the steering lever.

A forward structure of a motor vehicle has a cross member which connects the two A-columns with one another and which is used for fixing a steering column and a knee restraint. A strut is fixed on the forward structure and extends from the cross member to a transmission tunnel extending in the longitudinal direction of the vehicle. At least two mutually overlapping strut sections of the strut have a connection area which, under a load during a crash and after overcoming a force threshold, can be elongated in a longitudinal direction while absorbing energy. A force limiting device is provided in the connection area of the strut sections in the force transmission path. Consequently, after the force threshold is exceeded, an energy reduction is achieved during a predetermined lengthening path of the connecting strut and at a constant force level so that a yielding of the impact-loaded knee restraint together with the cross member takes place with a force-limited resistance along a predetermined path distance.

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.

Longitudinal adjusting arrangement on a casing tube telescope of a steering spindle in a motor vehicle comprises a spindle drive which has a threaded spindle extending in the longitudinal direction outside on the casing tube. The threaded spindle is supported on a first telescope section and, by means of its thread, engages in a spindle nut which is supported on a second telescope section arranged coaxially with respect to the first telescope section. In order to be able to reduce impact energy in this longitudinal adjusting arrangement in the case of a crash, at least one energy absorption element is fixed on at least one of the telescope sections, which energy absorption element, in the case of a movement, particularly an axial movement of the threaded spindle and/or of the spindle nut relative to the respective supporting telescope section, is acted upon by at least one of these parts of the spindle drive.

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.

Collision-protection device for vehicle passengers

A protective device for motor vehicle airbag systems to protect the vehicle occupants utilizes a vessel whose wall piece, which can break out, is configured as part of the wall of a hollow valve block provided with the outflow orifice. The wall piece is equipped with an extension projecting into the interior of a valve block. The piston rod is guided displaceably, transversely relative to the extension in the valve block, and moved by a pyrotechnic propellent charge. The rod serves to break out the wall part and is provided with a collar which, in the event of ignition, strikes against the extension and thus leads not to a violent breaking-out, but to a pivoting of the wall piece before the final breaking-out.

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.
