Definitions

  • the invention relates to a stepping mechanism for an adjustment device of a vehicle seat, which a) a hand lever which is pivotally mounted about a lever axis, b) a thumbwheel, which has a toothing and is rotatable about an axis parallel to the lever axis, c) two identical Carrier, which are each mounted pivotably about a driver axis on the hand lever, each having at least one driver tooth and of which in each case one driver is actively in driving engagement with the toothing in a rotational direction of the hand lever, wherein its driver tooth comes into engagement with the toothing and the adjusting wheel rotates, and d) has a spring which biases the hand lever into a zero position, wherein a respective stop flank is provided for each pivoting direction of the hand lever.
  • the invention aims to more precisely detect, control and specify operations during operation of the stepper to cause both drivers to return to an ideal home position when the hand lever is returned to the neutral position. In this neutral starting position, the hand lever is preloaded by a suitable zero-position spring.
  • the object of the invention is to develop the stepping mechanism of the type mentioned in that after an operating stroke and during the return movement of the hand lever of the previously active driver is brought into a precise starting position, which ensures an intervention of this at least one driver in a subsequent operating stroke so that idle stroke is avoided and other types of mishaps can not occur.
  • this object is achieved in that the stop edge is provided on the hand lever or on each of the drivers, and that the stop edge is in a maximum pivoted position of the hand lever in contact with a tooth of the toothing and another swinging limited by the hand lever.
  • the invention also proposes to limit the maximum swivel position of the hand lever in a state in which the active dog tooth has moved the toothing into a position in which the toothing is moved beyond the neutral stroke by an overcenter stroke, the overstroke being at least a portion of a clearance between the active dog tooth and the adjacent tooth flank of the toothing prior to the power stroke.
  • the setting wheel at the end of the actuating stroke is not mirror-symmetrical to a mirror plane which is determined by the lever axis and the axis of the setting wheel. It's about his middle position moves. In other words, the setting wheel is therefore rotated slightly further in the drive direction than is actually necessary.
  • the overstroke can be defined as follows: When the hand lever is in its neutral starting position, the teeth of the two drivers have a certain sen free distance to the nearest flank of the toothing of the setting wheel. This closest flank is located on the side of the driving tooth on which the other driving tooth is located. In other words, the nearest flank is in each case between the driver teeth of the two drivers.
  • the free distance of a driving tooth to the nearest flank of the toothing when a drive is done, must first be overcome, it is lost for the drive movement.
  • the overtravel is now chosen so that it corresponds to at least a part of the sum of the free distances of the two driver teeth and a maximum of this sum, preferably it corresponds to half of this sum.
  • the driving carrier can be moved by the amount of overstroke, which has the passive driver as a free distance. After completion of a working stroke is thus the passive driver in the immediate vicinity or even in contact with the nearest adjacent tooth flank of the toothing. If a return stroke then takes place in the other direction, this previously passive tooth can become active immediately; it has practically no free distance to overcome. It is then moved by an overstroke, which corresponds to at least part of the free distance of the other driver.
  • the overtravel is at least one tenth of the free distance that the other, passive driver of the adjacent tooth flank of the toothing has.
  • the teeth are each moved to a position shortly after twelve o'clock and, in the case of a counterclockwise drive, to a position just before twelve o'clock.
  • the teeth were each moved to the 12 o'clock position.
  • the 12 o'clock position is the middle position of the toothing
  • the middle position is a symmetrical position of the toothing.
  • the overstroke is equal to the arithmetic mean of the two free distances. If the free distance of the left driver tooth has the value u and if the free distance of the right driver tooth has the value v, then the overstroke is (u + v) / 2.
  • the two stop flanks which come into contact with a tooth of the toothing, are preferably arranged on the drivers. They can also be arranged directly on the hand lever. They can be arranged at that point of the hand lever, which is closest to the setting wheel. Possible here is a cranking of the hand lever or another measure that causes a portion of the hand lever is located in the plane of the setting wheel. A partial region forms in each case a stop flank and can come into direct contact with the teeth, at least with one tooth, of the setting wheel. Preferably, the stop flanks are hardened.
  • the teeth Due to the overstroke, after completing a power stroke, the teeth are usually no longer mirror-symmetrical.
