Abstract: In the case of a control system for adjusting devices of a motor vehicle which, in addition to a basic mechanical function, carries out an additional function which can be achieved by electronic devices, having at least one sensor for an input value, one computer for converting the input value to an output value for a control element assigned to the additional function, and having an emergency device for an emergency measure in the case of an occurrence of a failure, the measures according to the invention are that a function chain consisting of the function step sensor(s), the computer(s) and an emergency device assigned to the control element, in contrast to the singly existing control element, have a redundant construction, that the elements of the function chains, which have the same effect, are monitored with respect to the same effect, and in that the emergency measure is triggered, when elements of the function chains which have the same effect exhibit a deviation by a given measurement.

Abstract: In a sliding door for motor vehicles, especially passenger motor vehicles, which for purposes of opening is lowerable into the vehicle body, the door body assumes in the lowered position, in which it receives the window in the lowered position thereof, an essentially vertical position. A coupling is provided for the simultaneous movement of the door body and window.

Abstract: A convertible motor vehicle is provided with two rollover bars which can be swivelled out of a lowered inoperative position into an upwardly directed supporting position and back around a swivel axis fixed at the vehicle and extending essentially in the longitudinal direction of the vehicle. The rollover protection system can be integrated into conventional vehicle concepts in a particularly space-saving and advantageous manner and reduces the risk of injury in the case of a fast, sensor-controlling swinging-up of the rollover bars.

Abstract: An integral safety helmet is described in which a chin guard can be folded up. For the release of the chin guard, a central opening bar is provided on the front side of the chin guard. As a result, the locking mechanism can easily be opened by only one hand or by the thumb of the motorcyclist. In certain embodiments, the opening bar is designed as a two-armed lever having an upper arm and a lower lever arm. In this manner, the chin piece can be released in two different manners.

Abstract: An improved vibration absorber that overcomes deficiencies of known heavy vibration absorbers that require exact manufacturing tolerance for the rigidity of the absorber in order to generate a sufficiently large frequency range of the vibration absorber. The new vibration absorber has the purpose of covering a larger frequency range with a lower weight by having the absorber mass disposed to be pivotable around a pivot at one end and on an opposite side supports itself on the vehicle body through at least one bearing arrangement. The absorber mass and/or the bearing arrangement are slideably arranged with respect to the pivot. The vibration absorber may be used in vehicles which have a natural vibration in the low frequency range.

Abstract: A process for determining the effective air temperature in at least one pneumatic tire of a vehicle sensor. In addition to the temperature in proximity of the interior side of the rim of the respective vehicle wheel, the temperature in the immediate environment of a vehicle brake disk or brake drum as well as the temperature in the immediate environment of the vehicle is sensed. From these measured temperature values, the effective air temperature in the respective pneumatic vehicle tire is then calculated. A mechanism for carrying out the process is disclosed. A formula for combining the sensor temperatures is disclosed. Lastly specific locations for the sensors are disclosed.

Abstract: A control device is disclosed for stabilizing the rolling motion of a vehicle, having control elements which are arranged between the wheel carriers or wheel suspension members and the vehicle body. The control elements generate a stabilizer torque as a function of at least one cross-dynamic motional quantity at the front axle and rear axles, the stabilizer torques at the front axle and at the rear axle are being generated as a function of the measured and determined quantities of the yaw velocity, of the roll angle and of the roll angle rate.

Abstract: An ignition unit for internal combustion engines with an ignition coil having a ferromagnetic core integrated with a spark plug connector, about the main core of which is arranged a primary winding and a secondary winding surrounded by an insulating body; the ignition coil and the spark plug connector are so arranged to one another that the axial directions of the spark plug connector and of the main core of the ignition coil form at least approximately a right angle.

Abstract: An arrangement is disclosed for the apportioning if the idling air of internal-combustion engines having an adjustment motor for driving an adjusting member for changing a flow control cross-section and a supplementary device which can be actuated when the internal-combustion engine is rendered inoperative and is used for controlling the adjusting member into a minimum opening of the flow cross-section serving as an emergency cross-section. The supplementary device comprises two magnets arranged to mutually affect one another, one of the magnets being rendered essentially inoperative during the operation of the internal-combustion engine and thus during the operation of the arrangement.

Abstract: A process for the mounting of a tiltable cover at a vehicle roof includes the steps of, after the fastening of the tilt-out device of the roof to the underside of the roof, fastening a front cover end, through a roof opening, to a surrounding body so that it can be swivelled around a transverse shaft. Before the cover is swivelled into a closed position, which closes the roof opening, a gauging arrangement is mounted in the rear on the cover or on the vehicle roof which has a stop which, in the closed position, limits the swivelling-in of the cover. In its closed position, the cover is connected with a vertically adjustable cross-strut of the tilt-out device. The gauging arrangement may be formed by a magnetic or adhesive strip which is mounted at the rear cover area and projects toward the rear, or by a ledge which is placed on the vehicle roof in transverse direction and has a wall section which is directed downward through the roof opening, a stop being constructed at this wall section.

Abstract: In the case of previously known double-wishbone axles, it is difficult to achieve a sufficient longitudinal springiness required for the rolling comfort because, as a result of the longitudinal force occurring during the braking operation, the wheel carrier is "wound up", so that, in lateral view, a strong twisting occurs of the steering axis. Also, no optimization has been possible of the wheel suspension kinematics as well as of the steering geometry. The new wheel suspension system has the purpose of eliminating these disadvantages. For this purpose, in the case of a double-wishbone axle, a shock absorber tube is pivotably connected with a lower wishbone. An upper wishbone is connected by means of an arm with the shock absorber tube which is aligned approximately in parallel with respect to the longitudinal direction of the vehicle and, on the one hand, is fixedly connected with the shock absorber tube and, on the other hand, is connected by way of a pivot with the upper wishbone.

Abstract: A data bus system for vehicles in which the various subsystems communicate with one another via a common data bus is provided in which the subsystems are in each case connected with the data bus via a station. The stations have registers for the storage of data required and furnished by the corresponding connected user. These stations, for the reception of the data required by the corresponding subsystem, are continuously connected to the data bus, while the stations for the sequential transmitting of the data furnished by the corresponding subsystem are sequentially connected to the data bus for a time interval equaling the length of the data to be transmitted.

Abstract: An arrangement for the metered feed of a fuel, especially in the combustion space of an internal combustion engine, includes a valve guided and actuatable in a valve body via a stem which intermittently controls a discharge opening arranged in the valve body. The stem of the valve is hollow for the formation of a reservoir chamber which enables the arrangement to be used for a cryogenic gaseous fuel. Channels are arranged in the stem and connect the reservoir chamber with an overflow chamber in the valve body which is arranged adjacent the discharge opening. The channels can be swirl channels.
