Definitions
- the invention relates to a Wegverstell adopted for a vehicle seat having an electric motor for generating a drive movement, wherein the electric motor for transmitting its drive movement is operatively connected to a transmission, which is provided with a transmission housing, in which
- Vehicle seats in particular individual seats, are designed to be adjustable in the rule.
- the seat can be longitudinally displaceable, including a seat part of the vehicle seat is attached to an upper rail and the upper rail is longitudinally displaceable relative to a vehicle-mounted lower rail.
- a backrest part of the vehicle seat is hinged to the seat part pivotally.
- the linkage is hereby produced by fittings, the seat part side and backrest parts have components that are relatively pivotable or rotatable.
- fitting types often used catch fittings or wobble fittings.
- a manual or a motor-driven adjusting movement can be provided.
- electrical motors are usually used, in particular due to the DC network in motor vehicles electric DC motors. Since such DC motors usually provide drive movements at high speeds, which are not directly usable as adjusting movement, a reduction takes place by means of the transmission. With the stocky motion then the seat or a seat components is adjusted.
- the electric motors have detection means to determine the number of revolutions and / or speed of the engine can.
- This information is used by a control of the Wegverstell engaged to transfer the seat or its component in the desired stored position.
- this can lead to a large number of different electric motors, which is associated with high costs.
- high sampling frequencies are required due to the high speeds of the previously used electric motors, which in turn lead to a large amount of data to be processed, which in turn require powerful and expensive evaluation electronics.
- strong electromagnetic loads which in turn involve a lot of effort to achieve immunity to interference in the respective adjacent assemblies.
- Such a seat adjusting device in which detects the engine speed and from the position of the vehicle seat is calculated, is disclosed in DE 3527906 A1.
- a seat adjustment device is to be made possible, which requires a less powerful evaluation electronics than previous seat adjustment devices for the generation of predetermined adjustment paths.
- the transmission has at least one detection means, such as a sensor for determining the speed of a gear member or a dependent on the speed size.
- evaluation electronics should be arranged on the transmission for evaluation of signals provided by the at least one detection means. Unlike previous solutions, in which the detection means are arranged in the engine and due to the high rotational speeds of the motor shaft require a high sampling frequency, lower speeds can be used in the inventive solution due to the reduction taking place in the transmission. The usually significantly lower speeds lead to lower sampling frequencies, which in turn make a less powerful evaluation electronics required. On the other hand, if similarly powerful evaluation electronics are used as before, computing capacities for other applications are now available in the evaluation electronics. In addition, the disturbance behavior at low frequencies is significantly lower, which in turn has a positive effect on the surrounding peripheral electronics.
- the inventive solution allows technically less expensive engines that are suitable for both vehicle seats without memory function as well as seats with memory function. Since the detection means, in contrast to previously known solutions, are now advantageously arranged on or in the gearbox instead of the motor, it is now also possible to use motors for seat adjusting devices with a memory function which have no detection means for speed detection. Since these motors can also be used for seats without memory function, this can be used to standardize the electric motors with otherwise different Wegverstell Steinen. The motor or the drive unit can thus be provided as a standard component, which can lead to higher quantities and thus to lower costs of the individual electric motors.
- the measure provided according to the invention also contributes to providing the evaluation electronics for evaluating the signals provided by the at least one detection means completely or partially on the transmission and not on the engine. This also relieves the motor of functions and can be standardized.
- the at least one detection means is integrated into the evaluation electronics, in particular is arranged on a common board with the evaluation electronics.
- the object is achieved according to the invention in a seat adjustment of the type mentioned also in that an electrical connection to the power supply and / or data exchange is provided on the transmission and that further the transmission is provided with means for supplying power from the transmission to the motor for the power supply of the latter, in particular for the generation of a motor drive movement.
- the transmission at least one electrical contact is present, as for the power supply and / or data exchange between the electric motor and the transmission Interface can be defined.
- the electrical contacting of the motor it is preferable for the electrical contacting of the motor to take place via the transmission.
- the transmission and the motor can each be provided with a contact means which can be connected to each other.
- the contact means can in this case be directly connected to each other and be designed to the type of plug / socket.
- the electrical contact means of the transmission and the motor may also be interconnected with conduit means.
- the transmission is also provided with a control unit which is arranged on the transmission itself.
- the control unit can advantageously take over all the control functions that are required for the execution of movements of the respective seat. It can also be provided that the control unit only controls the functions that are required for the operation of the respective drive of the seat adjustment device. It has proven to be advantageous in this case if the control unit has a circuit board with electronic circuits, wherein the circuit board is arranged on the transmission, preferably on the transmission housing and particularly preferably within the housing, whereby the control unit is protected against damage and contamination.
- the control unit may contain both the required control electronics and power electronics for the motor.
- At least one sensor designed as a detection means can be provided on the transmission, with which information relating to the rotational movement of a rotatably arranged transmission element can be determined.
- a sensor may advantageously be an inductive or magnetic effects sensor, such as a Hall sensor.
- the magnets required in connection with Hall sensors can be mounted in different ways on the rotating gear member, for example, be glued. However, it is particularly preferred if inexpensive plastic sintered material is magnetized at predetermined locations of the gear element provided for this purpose. In this way, eliminates the complex measure of integration of additional magnets.
- the manufacturing processes required for this purpose are known per se and are offered and carried out, for example, by the company MS-Schramberg GmbH & Co. KG, D-78713 Schramberg-Sulgen.
- the at least one sensor preferably a Hall sensor, provided for detecting the rotational speed information can be integrated into the control unit, in particular arranged on a circuit board of the control unit.
- the control unit can advantageously be arranged on the transmission, in particular within the transmission housing such that the at least one magnet passes during the rotation of the gear member on the Hall sensor and this is detectable by the Hall sensor.
- the seat adjustment device in connection with the seat adjustment device according to the invention, it is possible to use any type of transmission which has at least one rotating transmission element.
- the invention may for example comprise at least one wobble, planetary, worm or helical gear and combinations of these types of gears.
- Particular advantages can be achieved with transmissions that have a high reduction ratio, since these transmissions - incurred in comparison to the respective speed of the drive motor particularly low speeds.

- the worm wheel 15 in turn meshes with a spur gear 16, which is arranged on a transmission-side output shaft.
- a further gear not shown in the figures is also arranged, which is in engagement with a rack of the lower rail.
- the rotational movement of the drive motor 11 thus leads to a reduction of the drive movement, preferably in the ratio of a range of 150: 1 to 250: 1, which in turn leads to a translational movement of the upper rails 5b, 6b and thus of the seat in the vehicle longitudinal direction.
- the transmission 13 has a housing 19, on the outside of which a first electrical contact plug 20 is provided which may be designed as a bus contact plug.
