Die Erfindung betrifft eine Verbindungseinrichtung zur Übertragung von elektrischem Strom, insbesondere für eine Lenkradheizung eines Kraftfahrzeugs zwischen einem feststehenden Gehäuseteil und einem gegenüber dem Gehäuseteil drehbaren Rotor, umfassend ein Flachbandkabel und im Bereich der freien Enden des Flachbandkabels vorgesehene Endsteckverbinder. Die Erfindung kennzeichnet sich dadurch, dass das Flachbandkabel einen zwischen den Endsteckverbindern gelegenen, zur rotorseitigen beziehungsweise gehäuseseitigen Anordnung vorgesehenen Zentralsteckverbinder aufweist, von dem jeweils wenigstens eine Leitung zu dem einen Endsteckverbinder und zu dem anderen Endsteckverbinder verläuft, wobei die beiden Endsteckverbinder zur gehäuseseitigen beziehungsweise rotorseitigen Anordnung vorgesehen sind. Die Erfindung betrifft ferner eine Lenkstock-Lenkrad-Übertragungseinheit mit einer derartigen Verbindungsvorrichtung.
Abstract:
A switch system capable of being automatically configured and used with any electrical system, particularly vehicle electrical systems, having an operator-activated control and an electrical device. This switch system generally includes an electro-mechanical switch and a switch module. Upon activation of an operator-activated control, such as a turn signal lever, the electro-mechanical switch sends an electrical activation signal to the switch module. The switch module uses an electrical identification signal, also obtained from the electro-mechanical switch, and a look-up table to convert the activation signal into an electronic control message. The electronic control message is then used to control a corresponding electrical device, such as a turn signal lamp. A particular electro-mechanical switch embodiment providing error detecting capabilities is also shown.

The invention concerns a conductor-strip maintained by one of its edges against at least a plate coated with an insulating material on its surface oriented towards said conductor-strip. The insulating material is a foam and the edge of the conductor-strip is rounded and directly pressed against said foam.
Abstract:
A horn or other vehicle device can be activated or controlled by attenuating light. A horn switch, or an optical switch, has a light source (1), light detector (2), and a pathway (3) for light extending through a void. The switches are activated by attenuating the light emitted by the light source. The light can be attenuated by at least partially obstructing the light or by modifying the orientation of either the light detector or the light source.
Abstract:
The invention relates to a steering shaft arrangement comprising a first housing (9), which accommodates a contact roller (10), the first housing (9) being divided up into a first and second section (13, 14), of which the first section (13) is connected to a steering shaft (1) and the second section (14) is connected to a steering column (6), fixed in relation to the steering shaft (1), the contact roller (10) comprising at least one electrical conductor, which is arranged between the first and the second section (13, 14). A second housing (11) is divided up into a first and second element (19, 20), of which the first element (19) is connected to the steering shaft (1). The second element (20) of the second housing (11) is detachably connected to the second section (14) of the first housing (9).
Abstract:
The inventive model with an angle sensor technology, energy transmission and information transmission consists of at least two printed circuit boards (1, 2). One printed circuit board (1) forms the stator with regard to the angle sensor technology and the remaining printed circuit board (2) forms the rotor with regard to the angle sensor technology. The stator, in addition to the primary coil for the angle sensor technology, contains an exciting coil for the energy transmission and the information transmission. The rotor, in addition to the secondary coil of the angle sensor technology, contains a receiver coil for the energy transmission and the information transmission. The exciting coil and the receiver coil are arranged on the respective printed circuit board in a circular manner in such a way that a coupling for the exciting coil and the receiver coil results, whereby said coupling is independent from the angle. The exciting coil and the receiver coil are used for the energy as well as for the information transmission. The energy is typically transmitted by means of a medium frequency of 25 kHz for instance. A modulation is superimposed over said medium frequency for the information transmission. According to the invention, various modulation methods, such as HF modulation (high-frequency modulation), amplitude modulation or phase modulation for instance, are possible.
Abstract:
An external locking clockspring assembly including a housing (30) and a hub (20) rotatively mounted in the housing. The housing having a first (32) and a second (22) keyway. The first and second keyways being substantially coaxial in a locked position of the external clockspring assembly. A key (10) insertable into both the first and second keyways. The key having a flexible tab. The mutual engagement of the key with the keyways prevents the hub from rotating relative to the housing.
Abstract:
A wireless rotating signal transducer. A control circuit is provided for transferring power and communication signals through a wireless coupling device (56) in a vehicle steering column. A squib firing circuit (62) transforms a high energy power signal suitable for firing an air-bag (46) from the column side to the wheel side. A low energy power circuit (54) generates a signal from the column side to the wheel side suitable for operating isolated wheel side electronics, such as cruise control, and the like. A pulse-encoder circuit (104) communicates low-level control signals suitable for signalling wheel-side commands from the wheel side to the column side. The low energy power circuit (54) and pulse circuit (104) operate simultaneously and continuously without signal debilitating interaction.
Abstract:
The invention relates to a device for the transmission of electric current between two components that can be turned in relation to one another of a steering device for motor vehicles, comprising a rotor (2) assigned to the steering wheel and turning with said steering wheel, a stator (1) assigned to a stationary subassembly of the motor vehicle and conductor strips (40) mounted on a flexible conductor plate (3) having a flexible support (30). Said conductor plate extends from the rotor (2) to the stator (1) and can be wound on a winding element (21) depending on the sense of rotation when the steering wheel is turned or is wound by said winding element. According to the invention, the conductor strips (40) extend lengthwise next to each other at a defined distance from one another in an elongated windable section (31) of the flexible support (30) of the flexible conductor plate (3) and the distance between the individual conductor strips (40) increases in the area of the ends (32, 33) on the stator and/or rotor side of the conductor plate (3).
