    摘要: In order that a signal can be transmitted without contact from a stationary vehicle part to a rotationally mounted vehicle part, in the case of axial displacement between the parts, provision is made for a rotary transformer having pot-type cores for primary and secondary windings which have L-shaped profiles. These pot-type cores are mounted coaxially inside each other such that one or a plurality of air gaps existing between them run parallel to the rotational axis and are intersected by the magnetic flux radially with respect to the rotational axis. One of the surfaces of the two pot-type cores bordering on the air gaps is provided with a bevel, which tends to decrease the width of the air gap when an axial displacement lengthens the path of the magnetic flux. One of the pot-type cores may include a plurality of ring segments.

    摘要: An arrangement for contactless transmission of signals, e.g., between at least one circuit unit installed on the vehicle body and at least one circuit unit in a vehicle seat mounted displaceably on rails is described. This arrangement is free of wear and guarantees interference-free signal transmission. This arrangement consists of at least one repeating coil whose primary winding and secondary winding are in separate pot-type cores, one of which is mounted on a stationary vehicle part (body) and the other is mounted on the movable vehicle part (vehicle seat). Both pot-type cores are designed as rails sliding along one another and having sections such that together they form a closed circuit for the magnetic flux between the primary winding and the secondary winding.

    摘要: The transfer unit which brings about the signal connection between an airbag installed in a steering wheel and a circuit arranged outside the steering wheel possesses a primary and a secondary winding which are located in separate annular dished cores which are mounted rotatably with respect to one another about the steering wheel axis. To ensure that the transfer unit transfers airbag measurement signals with minimal falsification, one of its two dished cores is equipped with a U-shaped cross section, and the other dished core projects into the latter, so that the magnetic flux intersects the air gaps remaining between the two dished cores preferably in a direction radial to the rotation axis.

    摘要: The apparatus for determining rotational position of a rotatable element without contacting it includes a sensor device having two Hall or AMR sensor elements for sensing a magnetic field of magnetic field strength (B) generated by or influenced by the rotational position of the rotatable element and for producing output signals according to the magnetic field and thus the rotational position of the rotatable element. In order to easily detect the absolute rotational position of the rotatable element, the sensor device is constructed and positioned with respect to the rotatable element so that in every rotational position the field lines from the rotatable element extend at right angles to the sensor structures defined by the direction of an alternating current in the sensor elements. Using different embodiments of an electronic evaluation circuit, the direction components of the magnetic field are evaluated to determine the rotational position by comparing the input current to one of the sensors and the sum of the output signals of the respective sensor elements. Either sinusoidal or rectangular alternating voltages or direct voltages are input to the sensor elements.

    摘要: A synchronous rectifier, to which the primary-side input voltage of the transformer and a control voltage with the same frequency as the input voltage is applied, is connected to the primary side of the transformer. The phase of the control voltage can be switched between 0.degree. and 90.degree., so that the output voltage of the synchronous rectifier corresponds exclusively to the voltage drop component at the ohmic input resistance of the transformer at 0.degree., and exclusively to the voltage drop component at the inductive input resistance of the transformer at 90.degree.. Since both the ohmic and the inductive input resistances are dependent on the resistance of the load connected to the secondary side (e.g., the squib of an air bag), both voltage components can be used to obtain reliable information on the status of the load resistance.

    摘要: The arrangement includes a transformer whose primary winding and secondary winding are in separate pot cores which can rotate in opposite directions about the axis of rotation of the steering wheel. To prevent these transformers from transferring energy to the squib which could deploy the air bag when a short-circuit to lines carrying on-board voltage occurs on its primary side, only one of the two pot cores is designed as a closed ring and the other pot core is made of one or more ring segments.

    摘要: A belt lock (8) for receiving an attachment element (2) of a safety belt (1) has an insertion opening (10) for the attachment element (2). In the belt lock (8), a connection element (20) is provided, which penetrates a locking opening (3) on the attachment element (2). The connection element (20) is disposed on a flat spring-type carrier (17), via which an insertion movement (24) of the connection element (20) into the locking opening (3) of the attachment element (2) takes place, when the attachment element operates a locking lever (12) by its insertion movement. The insertion movement (24) of the connection element (20) is monitored via a magnetic circuit containing a magnetic field-sensing sensor (31). A component (11, 20) of the belt lock (8) that fixes the attachment element (2) of the safety belt (1) is associated with a measuring element (20), with which a force operating on the belt lock can be determined via the magnetic circuit (16, 31).
