Problems solved by technology

[0009] In the case of small servomotors, this power is generally generated at high rotational speeds, so that in the case of variably present loads, the operating rotational speed is sometimes in a range in which the pulse rate delivered by the sensor does not vary. Can then be processed by commonly used controllers on the market and lead to failure of the control device or the drive system

Embodiment Construction

[0022] The drive device as a whole is marked with the reference numeral 10 in the figures.

[0023] In the exemplary embodiment, the drive device 10 is provided for actuating a headrest 11 which is adjustable in directions z1 and z2 and which is mounted on a backrest 12 of a vehicle seat 13 . The head restraint 11 includes a head part 14 and a carrying rod 15 . The head part 14 is held on a carrying rod 15 . The carrier bar 15 itself is supported in a support fastened to the backrest. The head part 14 is mounted movably relative to the backrest 12 in the directions z1 and z2 by means of an electric servomotor 16 . The head part 14 is movable, for example, relative to a support rod 15 , and the support rod 15 is mounted immovably, for example, relative to the backrest 12 .

[0024] According to an alternative embodiment, the support rod 15 is displaceable relative to a support fastened to the backrest by means of a servomotor, wherein the head part 14 is immovably mounted re...

Abstract

In particular, the invention relates to a drive device (10) for a vehicle cabin fitting (13), comprising a servomotor (16) and a controller (17), the servomotor (16) being controlled by the controller (17) ) is controlled, the servo motor (16) is equipped with a sensor that measures the rotational speed (nMotor) of the servo motor (16) and sends the pulse rate (PMotor) corresponding to the rotational speed to the controller (17). The special In that, a pulse rate corrector (18) is connected between the sensor of the servo motor (16) and the controller (17), and the pulse rate corrector corrects the pulse rate (PMotor) received by the servo motor (16) , so that the pulse rate is within the value range (PSteuergeraet Max) of the pulse rate that needs to be processed by the controller (17), and the pulse rate corrector (18) further delivers the corrected value (PReduz) of the pulse rate to controller (17).

Description

technical field [0001] The invention relates to a drive device for a vehicle cabin fitting. The vehicle is, for example, a land vehicle, an aircraft or a water vehicle. Background technique [0002] Such drive devices are known from obvious prior use. Accessories such as height-adjustable head restraints of vehicle seats are equipped with electric servomotors which move the head part of the head restraint relative to the backrest, for example up / down. The servomotor is controlled by a control unit, for example a seat control unit, according to a desired adjustment path and a desired adjustment direction. [0003] In this case, the seat controller uses the signal of the servomotor so that the servomotor is supplied with a pulse rate form corresponding to the rotational speed of the servomotor. For this purpose, the servomotor includes a sensor which detects the rotational speed and converts it into a pulse rate corresponding to the rotational speed. The sensor can be a Ha...
