The invention provides a method for operating a portable hand-held transmitter for a vehicle remote-control system in which a plurality of activation sequences control a plurality of assigned control functions in a normal operating mode, at least one control function being assigned to each prescribed activation sequence. The activation sequences differ in the manner and/or number of actuations of an activation mechanism of the portable transmitter. According to the invention the portable transmitter is switched over from the normal operating mode into a programming mode by means of a switch-over activation sequence which is carried out via the at least one activation mechanism. Assignments of the prescribed activation sequences and of the prescribed control functions can be changed as desired during the programming mode.

An automobile center console has an associated armrest with a lifting and transverse shifting mechanism that exerts on the armrest a combination of a lifting movement and a transverse displacement toward one of the two front seats. The lifting and transverse shifting mechanism is located on a guide carriage that is linearly movable by a linear guide device along the center console in the lengthwise direction of the vehicle.

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 firewall for a vehicle body including stable rigid side parts in the shape of an inverted U and a deformation insert connected in the part of the open central area of the inverted U. The deformation insert allows at least partial intrusion of assemblies from the engine compartment into the passenger compartment in the event of a vehicle collision. This design permits a shorter front end.

A shifting assembly for a change speed gearbox includes axially displaceable shift rods and pivotably displaceable shift rockers for actuating respective gear wheel clutches. Locking elements in the form of linear pins and pivotal members are abuttingly engaged with the respective shifting mechanisms so as to assure locking of all other shift rockers and shift rods when one of the shift rockers and shift rods is moved to a clutch actuating position.

The invention relates to a cylinder liner, cast into a reciprocating piston engine, of a highly hypereutectic aluminum/silicon alloy which is free of hard material particles independent of the melt and has such a composition that fine primary silicon crystals and intermetallic phases automatically form from the melt as hard particles. By spray-compacting, a blank of finely sprayed melt droplets is caused to grow, a fine distribution of the hard particles being produced by controlled introduction of small melt droplets. The blank can be transformed by an extrusion step into a form approximating the cylinder liner. After subsequent premachining with chip removal, the running surface is precision-machined and subsequently honed in at least one stage, after which the hard particles located in the running surface are exposed, plateau faces of the particles being formed, which faces protrude from the remaining surface of the matrix structure of the alloy. The exposing of the primary crystals and/or particles is effected chemically, using aqueous alkali. Owing to the fine-grained hard particles formed in the melt and to their large proportion in the matrix structure and owing to the exposing of the hard particles in the matrix structure, not only high wear resistance and a high load bearing proportion of the running surface result, but also the possibility of using inexpensive piston ring fittings and piston coatings with, at the same time, low oil consumption and correspondingly low hydrocarbon emissions.
摘要:
An elastic covering cap for a foot-pedal of a motor vehicle which can be produced economically, while functioning well and having a pleasing aesthetic effect. For this purpose, the covering cap includes, on its foot-rest surface, a multiplicity of studs which have a mushroom-like shape and over the mushroom heads of which a perforated ornamental plate can be snapped on so as to be form-lockingly fitted underneath the mushroom heads.

The invention relates to a method for protecting against unauthorized use of a vehicle which has bidirectional communication with a master station, whereby it is possible not only to transmit exclusively a position message of the vehicle to the master station or to transmit exclusively enabling signals to the vehicle from the master station, but also to make the communication appropriate to requirements. The necessary transmission of information is substantially reduced in that the enabling signal is broadcast only when requested by the vehicle. On the other hand, it is still not possible for the enabling to be carried out at the vehicle end only.

A hydraulic power steering system is provided in which a manual steering device and the steering vehicle wheels are normally coupled only by way of a control path with a desired-value generator operated by the manual steering device and an actual-value generator operated by the steering vehicle wheels. For controlling a hydraulic servomotor used for the steering operation of the steering vehicle wheels, a servo valve arrangement is operated by a desired-value/actual-value comparison. Only when there is a disturbance in the control path, will a hydraulic forced coupling take place between the manual steering device and the steering vehicle wheels.

The vehicle air-conditioning system according to the invention has at least one air-conditioning air duct with at least one air outflow nozzle having an automatically adjustable air guiding arrangement, a sun radiation sensing system, and an air-conditioning control unit which generates control commands for automatically adjusting the air guiding arrangement at least as a function of the output signals of the sun radiation sensing system. The air-conditioning control unit uses output signals from the sun radiation sensing system to determine the local distribution of sun radiation in the area of a particular vehicle seat and, as a function thereof, automatically adjusts the air guiding arrangement or arrangements assigned to the respective vehicle seat.
