Abstract: A transmission for motor vehicles having a conical-disc band transmission placed in a casing, a reduction gear and, if necessary, a differential. In order to achieve an optimum transmission-ratio range for motor vehicles and good efficiency, the reduction gear contains two forward speeds and is connected to a fixed gear on the power take-off shaft by means of an additional fixed gear. The driving disc pairs of the conical-disc band transmission are located directly on a section of the drive shaft and on the power take-off shaft. The reduction gear and the conical-disc band transmission can be actuated by means of conventional synchronous clutches. The transmission case is longitudinally fitted with a center wall which subdivides the space into two compartments, one of which is closed by a front cover and the other by a rear cover. While one compartment contains the reduction gear and, if necessary, the differential, the other compartment contains the conical-disc band transmission.

Abstract: The invention relates to a coupling means between an output control member of an internal combustion engine, in particular for automotive vehicles, and an actuator member, which coupling means in the range of small actuations of the actuator member does not open the output control member at all or only slightly, and only at larger actuations does it open the output control member in a noticeable fashion and thereafter moves it into a full-load position. Such a coupling means makes possible an enlarged operative range for a control device which controls the output control member in dependency of the position of the actuator member and at least one operating parameter of the internal combustion engine in a range lying between the full-load position and the minimum opening position determined by the given position of the actuator member.

Abstract: A gasket for use with window panes, such as windshields, fixedly mounted into a window opening of an automotive vehicle. The gasket is affixed to the margin of the window pane, and a base portion of the gasket is removably inserted into the gap formed between the edge of the pane and the surrounding wall portion of the window opening.

Abstract: This invention relates to a guidance system for window panes in vehicles, comprising three points of guidance only, one of the points of guidance coinciding with the lifting mechanism. As the pane may be rotated about each one of these points of guidance, the system avoids the occurrance of bending stresses, and a function-related maximum number of degrees of freedom at each point of guidance obviates redundancy, thus providing a smooth and precise guidance of the pane.

Abstract: A mount for securing together two relatively displaceable bodies, such as a motor-vehicle engine and a vehicle chassis, with limited relative freedom of movement has a substantially closed liquid-filled chamber formed by a first resiliently deformable wall and a second wall which may be rigid or resiliently deformable. A partition subdivides this chamber into a pair of compartments and has an elastically deformable and relatively stiff portion and an elastically deformable and relatively yieldable portion. One of these portions is formed with a throughgoing orifice. Stops are provided on each side of the relatively yieldable portion to limit the deflection thereof so that low-amplitude vibrations are not transmitted between the bodies, but high-amplitude vibrations are damped when the yieldable portion abuts the stops.

Abstract: A transmission comprises a rotatable output; a rotatable input; three planetary gear sets each having rotatable first, second and third elements and planet gears; rigid rotatable couplings connecting the second element of each set with one element of one other set and connecting the third element of each set with a different element of one other set, the remaining elements of each set being uncoupled and being of the same kind; a brake for locking each coupling against rotation; the uncoupled element of one set being driven by the input and the uncoupled element of a second set driving the output; and a clutch arrangement for selectively connecting the uncoupled element of the third set with either or both of the uncoupled elements of the first and second sets.

Abstract: A passive knee restraint for an automotive vehicle is formed by the yieldable rearwardly facing lower wall of a dashboard portion positioned to engage the knees of a seated passenger in an automotive vehicle, thereby restraining the lower portion of the body of the passenger in the seat in the event of sudden vehicle deceleration. According to the invention, this dashboard portion is at least partly swingable on the remainder of the dashboard to afford unrestricted access to the region behind it, thereby allowing repair and maintenance in this region and/or access to articles stored therein as, for example, when a glove compartment is provided behind this swingable part.

Abstract: A window-guiding and sealing assembly for use particularly in a door of a passenger-type automotive vehicle having a window frame comprises a guide member directly attached to the window along a substantially vertical edge thereof and projecting into the interior of the vehicle, this guide member being slidably mounted in a vertical guide rail on the vehicle body. A hollow substantially oval sealing strip is integrally formed with a holder having a resilient clip for forming a snap-lock engagement with a flange and a recess along the members of the window frame, the holder having a guide surface on a horizontal portion for facilitating the engagement of an upper part of the window pane and a horizontal section of the sealing strip upon a closing of the window assembly. The holder is further provided along its entire length with an inwardly facing shoulder for engaging another hollow sealing strip attached to the door frame.

Abstract: A motor-vehicle door has a generally annular door frame having an inner side and outer side respectively releasably connected to inner and outer door panels. A hinge is connected to one vertical edge of the frame between the sides and a latch to the opposite edge. A window pane is vertically displaceable in and above the frame and the mechanism for operating this window and for operating the latch are fixed to the inner panel. The frame is formed by a pair of frame parts together forming a tubular box-girder structure on the two upright sides and lower edge of the door for maximum rigidity.

Abstract: In an arrangement according to this disclosure, a spring element (3, 7) is arranged between a mounting core member (2) and a support (6) and is connected to a damper mass (9, 12). The damper mass has a container (10) which is filled with pressure liquid and/or gas and closed by a diaphragm (13). The spring rate of the diaphragm can be varied as desired, particularly in dependence on the speed of rotation of the machine or engine. For varying the spring rate of the diaphragm, a pressure plate (15) is associated with the diaphragm, and is displaceable relative to the diaphragm by way of an adjusting arrangement (16, 17) dependent on the speed of rotation of the machine or engine, and the relative configurations of the pressure plate and the facing diaphragm are such that this displacement reduces or increases the free area of the diaphragm, and thus varies its spring rate.

Abstract: An internal-combustion engine having an electric starting motor, an ignition system, and an electric power source is provided with a control system allowing the engine to be stopped and restarted very easily. This system comprises a main ignition switch connected in series between the power source and the ignition system and closable to energize the ignition system from the power source. A manual start switch and an automatic start switch are connected in series between the main ignition switch and the electric starting motor and both are closable when the main ignition switch is closed to energize the starting motor from the power source. A speed-sensing circuit is connected to the engine and to the automatic start switch and is set up to open the automatic start switch and thereby deenergize the start motor when the engine is operating above a predetermined rate of approximately 500 rpm.

Abstract: A windshield wiper is operated by a wiper motor from an electric source, with a control circuit operating the motor. This control circuit has a continuous-wipe switch which when closed operates the wiper continuously. A discontinuous-wipe switch can be closed to start an oscillator, with this oscillator connected to a backward counter which counts backwardly synchronously with the oscillator. A comparator compares the instantaneous numerical output of the counter with a fixed numerical output generated by a settable memory, and operates the wiper briefly when the two outputs agree. A set switch is connected to the memory and can reset it so that when this set switch is operated the fixed numerical output of the memory is fixed at the instantaneous numerical output of the counter, thereby setting the interval between successive wipes of the wiper.

Abstract: A turbocharged engine system has an internal-combustion engine whose exhaust gases drive a turbine at a speed generally proportional to the exhaust-gas pressure. This turbine in turn drives a supercharger that feeds air to the engine intake at a pressure that is generally proportional to the turbine speed. A bypass valve connected across the turbine is opened above a predetermined engine speed to shunt the exhaust gases around the turbine and thereby prevent excessive supercharging of the engine. The pressure of the engine exhaust gases is, however, decreased steadily and proportionately with increasing engine speed above a predetermined second engine speed to operate the engine with an intake-manifold pressure that is slightly below that at which knocking would occur for increased horsepower output.

Abstract: A window assembly, especially for the side door or doors of an automotive vehicle, comprises a window frame having a pair of generally parallel rails formed as channels opening toward a window pane which can be raised and lowered on the vehicle. The window pane is provided with guide shoes or like members received in and guided on the respective channels and affixed to the pane inwardly of respective edges thereof so that these edges can be engaged, even along the face of the pane provided with the shoes or guide members, by seals on the frame or vehicle body.

Abstract: An automotive vehicle seat has a portion of its back part or seat part which can be pivoted or slid into a position above the sitting surface of the seat part and in front of the leaning surface of the back part. This portion is U-shaped and constitutes a passive child restraint having a pair of parallel legs extending in the direction of travel and a front cross piece, all padded. When out of use the U-shaped restraint bar may be pushed back level with the front surface of the back part of the seat or the top surface of the seat part of the seat.

Abstract: A hydraulic power-steering system has a reversing spool-type valve whose spool may be displaced by the steering wheel and which is connected between a hydraulic pump and a power cylinder in turn connected to the vehicle wheels. This power cylinder has a piston whose effective surface areas exposed in respective chambers are of different size. The spool valve has a pair of input branches connected to the high-pressure side of the pump and a pair of output branches connected to the low-pressure side of the pump, and may assume an intermediate position in which each of the input branches is connected to a respective one of the output branches for hydrodynamic flow through the valve. In addition this valve has a pair of control ports connected to the respective chambers of the power cylinder, and connectable via respective compartments of the valve to respective input and output branches.

Abstract: A rear window for an automotive vehicle has imbedded at an upper portion thereof resistance-heating wires for the electrical heating of the window. A window wiper is provided to sweep the window which has a lower portion free from the heating conductors. In its rest (inoperative) position the wiper lies against a portion of the window provided with additional heating elements for rapidly heating the rest position of the wiper to free the wiper, if frozen to the window, to enable the wiper to be brought into play without delay.
