Abstract: A power seat adjuster includes first and second spaced track assemblies, each formed of an upper track slidably mounted in a lower track anchored to a vehicle floor. Each upper track is integrally formed as a one-piece member and has at least one pair of spaced mounting flanges integrally formed as a part thereof and extending outward from the upper track. Aligned apertures are formed in the mounting flanges to connect a tubular member extending between the track assemblies to the upper track of each track assembly. Another pair of mounting flanges may be formed at the opposite end of each upper track for mounting a second tubular member between and to the upper tracks of the track assemblies.

Abstract: A seamless double-walled tube having high corrosion resistance and relative flexibility prepared by a process for brazing non-ferritic steel surfaces such as nickel chromium or stainless steel to which a suitable brazing alloy such as copper has been mechanically attache which includes the steps of instantaneously elevating the surface of the stainless steel to a brazing temperature while maintaining the material in a humidified gaseous atmosphere consisting essentially of a non-reactive carrier gas and a reactive gas present in sufficient concentrations to achieve fluxing; maintaining the surface temperature of the steel for an interval sufficient to permit fusion between the selected metal and the non-ferritic steel surface; after metal fusion has been achieved, allowing the resulting fused metal material to cool to a first lowered temperature in a controlled non-oxidative atmosphere at a rate which retards the formation of fine-grained steel crystals in the metal; and after reaching a metallurgical transfo

Abstract: A circuit configuration for an anti-lock brake system, which receives input from wheel sensors positioned on the driven wheels, comprises a monitoring circuit (7) which triggers a test cycle (duration T.sub.Test) when the two wheels of a driven axle signal instability for more than a predefined time span (T) during a control cycle. By way of the test cycle, braking pressure is introduced into the wheel brake of the instantaneously slower wheel (v.sub.1, v.sub.min -wheel) of the driven axle and the reaction of the driven wheels to the braking pressure delivered is assessed.

Abstract: The proposed brake system eliminates breather bores and central valves in the working pistons of the master brake cylinder and establishes short-term pressure fluid connections between the supply reservoir and the working chambers when the brake is not applied by controlling replenishment valves and outlet valves. Therefore, connection of the supply reservoir to the working chambers of the working cylinder is constituted solely via electromagnetically controllable connections.

Abstract: A drive device for wipers of motor vehicles includes a shaft extending a front face of a bearing housing and with a cylindrical slide bearing which is inserted into the bearing housing at little distance from the front face of said bearing housing, and with a ring groove limited by the slide bearing, the bearing housing and the shaft. A bush firmly fixed to the bearing housing and made of elastic material closes the ring groove in front of the slide bearing and at its end turned off from the bearing housing comprises a sealing flange radially projecting towards the inside, which sealing flange engages into a ring groove of the shaft.

Abstract: A hydraulic anti-locking brake unit is presented in which the brake line is shut off by an isolating valve (20) during a control action. For the reduction of the pressure, the outlet valve (7) is opened, so that the pump (14) delivers hydraulic fluid out of the wheel brake into the high-pressure accumulator (19). For a renewed pressure build up, the inlet valve (6) is opened, so that hydraulic fluid flow is directed out of the high-pressure accumulator (19) back to the wheel brake. In order to be able to utilize a high-pressure accumulator having a low receiving capacity, various valving arrangements are disclosed to direct excess flow from the pump either to the master cylinder or a low pressure accumulator.

Abstract: A circuit configuration for an anti-locking brake system controlled according to a multiplex process. The circuit configuration is designed such that upon commencement of an anti-locking control, if the first wheel to become instable is a front wheel (VL) the reswitching of the wheel valves (4) leading to the rear wheel brakes (22, 23), is delayed by a predetermined period of time of about 4 to 20 milliseconds. This therefore prevents the pressure from excessively rising upon commencement of the anti-locking control.

Abstract: A radial piston pump is described with dual pistons which are slidingly accommodated within a bushing coupled end to end to a valve body. Automatically controlled suction and discharge valves for a pressure chamber are arranged one behind the other in the longitudinal axis of the pump. The pistons are sealed by means of elastomeric seals compressed by an end of the valve body and bushing under pressure of a threaded sealing plug installed in the pump housing. The valves, valve body and bushing form a cartridge separately assembled and installed as a unit in the housing. The threaded sealing plug is formed with a damping chamber for damping of pressure pulsations.

Abstract: An automotive seating system including lightweight, high strength extrusions forming the track assemblies. The extrusions are formed with elongated abutment surfaces providing the sole reaction surfaces to resist separation of the track assemblies in the event of a crash. No separate reinforcements are needed.

Abstract: An arm connectible to a seat back and having teeth formed at one end is pivotally mounted to a seat bottom frame formed of first and second spaced, fixedly connected plates. A toothed drive gear mounted between the first and second plates and rotated by a drive unit meshingly engages the teeth on the arm to rotate the arm between infinitely adjustable positions. Aligned slots are formed in the first and second plates and receive opposed tenons of a rivet having the arm rotatably mounted about a central body portion.

Abstract: A brake system is presented wherein a pump receives the pressure fluid that is discharged out of the wheel brakes during a control action and supplies it into a high-pressure accumulator. Further, there is provision of a separating valve which closes the brake line during a brake slip control action. The separating valve is actuated mechanically, and namely by the accumulator piston of the high-pressure accumulator. The advantage thereof is that the force of the greatly biased accumulator spring is available for cracking the separating valve open. It is thus ensured in any case that the separating valve is re-opened after a slip-controlled braking operation and renewed braking of the vehicle is possible.

Abstract: A squeeze-to-release quick connector for engaging a flanged male member includes a cylindrical body portion which is open at one end for receiving the male member and forms a conduit receiving adapter at its opposite end. An annular retainer ring is axially spaced from the open end and is attached to the body portion by two circumferentially opposed, generally parallel axially elongated beam members. Each beam member is affixed at one end to the retaining ring and at an opposed end to a mount located on the body portion axially spaced from the open end. Two circumferentially spaced detents extend inwardly from a retaining ring to capture the male abutment surface to effect positive engagement therebetween.

Abstract: An actuating unit for hydraulic automotive vehicle brake systems, including a vacuum brake power booster, a master brake cylinder, and an operating element, configured to achieve a reduction of overall axial length and a simultaneous reduction of the weight and a relief of the booster housing from forces of reaction. The brake pedal (3) operating arm is interposed between the vacuum brake power booster (1) and the master brake cylinder engaging an axially extending member interconnecting a control valve piston and a master cylinder piston (2). The booster housing (10) and fluid reservoir (4) are mounted within the engine compartment while the master cylinder housing has a flange portion fixed to the splashwall and a main portion which projects out of the engine compartment through the splash wall, and into the passenger compartment. The hydraulic reaction forces are absorbed directly from the master cylinder housing into the splashwall rather than through the booster housing.

Abstract: For evaluating the wheel speed signals (V(n)) required by an anti-locking or traction slip control system, a basic speed (VBas(n)) is derived from the speed signals of the individual wheels, and a wheel factor (Ki(n)) is formed for each wheel which, when multiplied by the wheel speed, forms the basic speed. For further signal processing, the wheel speed multiplied by the appertaining wheel factor is used in lieu of the actual wheel speed to form the reference speed, and the control signals.

Abstract: An anti-lock-controlled brake system with a auxiliary-force-assisted braking pressure generator accommodates a master cylinder in which at least one wheel brake is connected to a main pressure line, with an auxiliary hydraulic pressure pump connected to an auxiliary pressure line the system further includes wheel sensors and electronic circuits for detecting the rotational behavior of the wheels and for generating electric braking pressure control signals which, for the purpose of slip control, control the electromagnetically operable inlet valves and outlet valves inserted into the pressure medium lines. A pressure limiting valve is responsive to the pressure of the auxiliary pressure pump and to a pressure acting on the wheel brake to control the outlet pressure of the pump.

Abstract: An anti-locking hydraulic brake system is described which includes a pump, the output of which flows through a pressure valve (20), a damping chamber (24), a check valve (28) and a throttle (3I) and is delivered to a pressure connection in communication with the wheel brake conduit. To ensure, in a compact structural design, a noise-minimizing hydraulic pressure source, while avoiding a flow back of pressure fluid from the brake system into the damping device, a check valve (28) is integrated into the damping device. A pressure valve is integrated with the check valve and damping chamber, with an elastomeric elastic member disposed in the damping chamber to absorb pressure pulsations.

The improvement is that the operating piston of the two-position pilot valve (4) is prestressed by a spring (28) having a constant spring rate and that the cross section of the valve inlet (19) is smaller than the cross section of the valve discharge (20).

Abstract: A brake system with anti-lock and/or traction slip control, wherein quantities (.DELTA.t.sub.EV, .DELTA.t.sub.AV) determining the pressure in the wheel brakes (10, 11) are measured and assessed. A wheel pressure pattern (p(t)) is formed from these quantities by integration which, by approximation, represents the pressure variation in the wheel brakes (10, 11). The output signal of the integrator (20) is fed back to the control logic (16) and assessed for slip control and/or braking pressure control. For the integration, taken into account are the braking-pressure-increase and braking-pressure-decrease characteristic curves (P.sub.A, P.sub.E) and the initial conditions (21) which represent the initial pressure upon commencement of the control.
