Abstract: A magnetically actuated electric switch with a bistable reed switch and with a magnet adapted to be moved past the reed switch within a channel; in its normal position the magnet adheres at a soft iron core and, during occurrence of an acceleration above a predetermined threshold value, is thrown against a compression spring arranged at the other end of the channel; during the to movement, the magnet switches the reed switch into the one stable position and during the fro movement into the other stable position. The switch is suited as acceleration pick-up for vehicles, especially as impact sensor.

Abstract: A drive arrangement which includes a number of internal combustion engines which are adapted to be connected to a flow of working force through free wheeling or one way clutches and gears to a common output shaft. In addition to a flow of working force the individual internal combustion engines may be interconnected by another flow of a tractive force which is formed by gearing up gears and one way or free wheeling clutches. This flow of tractive force acts only in a direction of force flow which opposes the flow of the working force. The internal combustion engines may be mechanically arranged in parallel next to one another or in series behind one another with working or output shafts of the internal combustion engines being located parallel or in series one behind the other. The working shafts are connected with parallel gear stages which transmit at different ratios and have opposing force flows.

Abstract: A recirculating pumping device for an anti-locking two-circuit motor vehicle brake system, with the pumping device including one pump piston provided for each brake circuit. The pumping device recirculates brake fluid released from the wheel brake cylinder or cylinders to a master brake cylinder during an anti-locking regulating or control process. The pumping device includes piston pumps, with one pump being provided for each braking circuit of the braking system. The piston pumps are constructed as free piston pumps having working chambers connectable periodically to a pressure source provided on the vehicle through a valve. The valve is switchable at a predetermined switching frequency or may be vented to the tank of the pressure source. The pistons are preferably constructed as stepped pistons, so that the recirculating pumping device may be adapted to the pressure level of a pressure source already available on the vehicle by an appropriate selection of a ratio between the piston surfaces of the pistons.

The guide control rod includes spaced side walls extending in a longitudinal direction with guide sockets being positioned in an area of the respective ends of the guide control rods. Each side wall is formed by a single stamped or pressed plate element. The guide sockets are formed by collar portions which define mounting openings extending through the respective side walls. The collar portions have different diameters so as to enable the collar portions of the respective plate members to be pressed onto one another, thereby connecting the two plate members to each other.

Abstract: An adjusting mechanism is for position-adjustable connected structural parts, such as in a driving-belt tension mechanism with a clamping coverplate. In the mechanism a first structural part that must be adjusted with respect to a second structural part that has a rack or gearing, into which a pinion that, by a threaded member, is clamped to position both structural parts, engages in such a way that, when the screw connection is loose a mutual shifting of the parts can be achieved by turning the pinion. The pinion has a nut-like collar that has a rack-meshing profile and an inside profile which is in one embodiment loosely slipped about a screw of the threaded member, and in another embodiment, rotatably fixed relative to the screw of the threaded member.

Abstract: A drive control device for a motor vehicle with rear axle drive and equipped with an anti-blocking system. As part of a rotational speed sensor arrangement provided to determine the state of movement of the vehicle wheels, each of the non-driving front wheels has an associated rotational speed sensor and the two rear wheels have a common rotational speed sensor, which measures the rotational speed of the propeller shaft in the transmission system. A hydraulic actuator provided for brake pressure control corresponds in construction to that of a 4 channel anti-blocking system. These components are utilized for both the drive control and the anti-blocking control. An electronic control system of the drive control device, which processes the output signals of the rotational speed sensors, initially activates the right-hand rear wheel brake, as soon as a driving wheel starts to spin.

The displacer includes a working space or chamber containing a flow medium connected by at least one throttle to one of at least two springs which can be loaded by the flow medium. The two springs have different load-dependent spring rate changes whereby the distribution of the volume proportions of flow medium displaced to the springs differs depending on the static flow medium pressure. At least one throttle which operates as a function of load is placed in front of the less progressive spring.

Abstract: In a control unit for a heating and/or air conditioning for automobiles with individual temperature control elements for two areas and with a common inside temperature sensor, the temperature of both areas can be adjusted or changed individually and independently of each other by directly activating both control elements by means of associated delay-value setters and by delaying the signal modification at the input of a common controller through the desired time setters for a sufficient time until it is offset by a corresponding signal modification of the inside temperature sensor.

Abstract: A gas cushion on the passenger side for motor vehicles, especially for passenger motor vehicles, includes two mutually oppositely disposed approximately trapezoidally shaped surface or boundary areas. The unique shape of the cushion provides a particularly safe protection effect in the critical upper impact area without increase of the overall volume of the gas cushion. One of the trapezoidally shaped boundary areas serves as impact surface facing the passenger while the other trapezoidally shaped boundary area includes at least one opening serving the gas admission. The gas cushion is so arranged in the motor vehicle that the trapezoidally shaped boundary areas taper from top to bottom.

Abstract: A bumper for a motor vehicle, with the bumper being equipped with an energy absorber provided along a rear surface thereof with at least one recess. The energy absorber is disposed forwardly of a girder subjected to bending, with the girder being attached to a vehicle. The recesses are arranged in such a manner that an impact force is transmitted to the body of the motor vehicle with as little moment as possible so as to prevent a tilting of the bumper and associated motor vehicle parts such as a fender of the vehicle. With a bumper girder subjected to bending being mounted forwardly of the energy absorber, at least portions of the recesses diagonally face the area of incidence of the impact force. If the impact is directly incident on the energy absorber, the recesses lie in an extension of a direction of the point of application of the impact forces.

The axle arrangement includes a wheel guide having an upper and lower split link for a wheel carrier. An instantaneous center located, in a rear view of the axle arrangement, a longitudinally extending center point of the vehicle is determined through the upper and lower links of the wheel guide. The instantaneous center travels out of the longitudinal center plane of the vehicle toward one side of the vehicle during a cornering. The links are constructed and arranged such that the instantaneous center shifts toward an inside of a curve during a cornering of the motor vehicle.
