Advantages, features and details of the invention will become apparent
the following description of two preferred embodiments
as well as from the drawings; these show in:
1 a schematic side view of a seat symbolizing a vehicle seat adjustment according to a first embodiment with two the seat cushion part or the backrest part representing the first adjustment switches, by means of which the vehicle seat is set in its Hauptverstellrichtungen, wherein in the first two adjustment each as adjusting, as adjusting or the like adjustment formed second adjusting switch are integrated, which in the present case survive with respect to the respective corresponding edge sides of the associated first adjusting switch, and wherein the respective axes of the two second adjusting switch extend in the extension direction of the corresponding first adjusting switch, and in
2 a schematic side view of a likewise representing a vehicle seat seat adjuster according to a second embodiment, in which each adjusting as adjusting, as adjusting or the like adjusting second adjustment are completely integrated within the corresponding first adjusting switch, wherein the respective axis of the corresponding second Verstellschalters transverse or is substantially perpendicular to the extension direction of the associated first adjustment switch.
In 1 is a schematic side view of a seat adjustment for a not further recognizable vehicle seat of a motor vehicle, in particular a passenger car according to a first embodiment shown. The seat adjustment device can be positioned, for example, on the seat cushion part or on the backrest part of the vehicle seat. Likewise, it is also conceivable that the present seat adjustment in the. Area of an interior trim, for example, a side door or a side wall of the motor vehicle, in particular the passenger car is arranged. Likewise, it is conceivable that the seat adjusting device is arranged in the region of a center console of the passenger car in a position which is easy to reach for the seat occupant in each case.
In the present case, the seat adjustment device represents the miniaturized vehicle seat, with two first adjustment switches 10 . 12 are provided, which schematically represent the seat cushion part or the backrest part of the vehicle seat.
The adjustment switch 10 for the seat cushion part is doing at its front end 14 in accordance with the adjustment direction shown by the double arrow 16 in Vehicle vertical direction or vertical direction movable up and down to adjust the seat angle of the seat cushion part. After the operation of the adjustment switch 10 up or down this returns to a middle or zero position. Furthermore, the adjustment switch 10 the seat cushion part according to the at the rear end by a double arrow 18 symbolized adjustment direction 18 in the vehicle vertical direction or vertical direction to move up and down to thereby adjust the seat height of the seat cushion part of the vehicle seat can. Finally, the adjustment switch 10 in one by the double arrow 20 symbolized, approximately horizontally extending adjustment 20 adjustable forwards or backwards. By operating the adjustment switch 10 along the adjustment direction 20 results in the seat longitudinal adjustment of the entire vehicle seat, which in the present case is supported electrically movable above seat guide rails. The three adjustment directions 16 . 18 . 20 thus symbolize the Hauptverstellrichtungen the seat cushion part or the vehicle seat.
The backrest part symbolizing adjustment 12 is according to the position of the backrest part diagonally opposite the adjustment 10 oriented. Here is the adjustment 12 at an upper end - substantially transversely or perpendicular to its extension direction - along an adjustment direction symbolized by the double arrow 22 to operate or move, which symbolizes the backrest tilt adjustment of the backrest portion of the vehicle seat. Opposite the upper end of the backrest part symbolizing adjustment 12 is a rotational axis of the backrest part indicated only schematically. Along its extension direction is the adjustment 12 beyond that by a double arrow 24 symbolized adjustment to move up or down to thereby vary the height of the seat back part accordingly. Overall, it can be seen that the two adjustment directions 22 . 24 of the adjustment switch 12 symbolize the Hauptverstellrichtungen the backrest part.
In the two, the seat cushion part and the backrest part of the vehicle seat representing adjusting 10 . 12 is in each case a further adjustment switch 26 . 28 integrated, which present as the respective adjustment 30 . 32 are formed. Both adjusting wheels 30 . 32 are formed substantially flat cylindrical with quarter-circle beveled Katen. Instead of the adjusting wheels used here 30 . 32 It would also be conceivable to use respective adjusting rollers or similar adjusting elements, which could be formed, for example, cylindrical or barrel-shaped. It is clear that it could be used within the scope of the invention, any type of adjustment, which is preferably rotationally symmetrical.
The two adjusting wheels 30 . 32 are each rotatable about an axis A at the corresponding first and second adjustment 10 . 12 arranged. In other words, the two are as adjusting wheels 30 . 32 trained further adjustment switch 26 . 28 in this case by the corresponding respective first adjustment switch 10 . 12 worn or stored on this. Both adjusting wheels 30 . 32 are located in a central or central longitudinal section of the corresponding adjustment 10 . 12 , It can be recognized that both axes A of the respective adjusting wheel 30 . 32 in the present case, essentially parallel to the direction of extent of the adjustment switches, each of which is designed as a rectangular cuboid 10 . 12 run. In other words, this results in an arrangement of the two adjusting wheels 30 . 32 , in which their respective direction of rotation (double arrows 31 . 33 ) about the axis A substantially transverse to the extension direction of the corresponding adjusting switch 10 . 12 is arranged. Furthermore, it is off 1 recognizable that each of the two adjusting wheels 30 . 32 opposite corresponding edge sides 34 . 35 of the adjustment switch 10 or border sides 36 . 37 of the adjustment switch 12 survives. In other words, the diameter of the respective Verstellrades 30 . 32 larger than the width of the respective adjustment switch 10 . 12 ,
By a respective rotation of the adjusting wheels 30 . 32 In the present case, so-called secondary functions of the vehicle seat are to be set. It is conceivable, for example, that by turning the in the adjustment 10 integrated adjusting wheel 30 a side cheek adjustment of the seat cushion part is done. Such a side cheek adjustment may, for example, refer to the changing distance or the changing pad hardness of the side cheeks of the seat cushion part, which changes depending on which direction the adjusting wheel 30 is rotated about the axis A. Furthermore, it would also be conceivable that by means of the adjusting wheel 30 the seat depth of the seat cushion part depending on the direction of rotation 31 is changed. Of course, it would be conceivable in this context, a variety of other secondary functions on the adjustment 30 adjustable to design. By means of the in the adjustment 12 integrated degree of adjustment 32 It is conceivable, for example, also make a side cheek adjustment of the backrest part. For example, it is conceivable to vary the distance or the pad hardness of the side cheeks of the backrest part in that the adjusting wheel 32 about the axis A in one or the other direction 33 is adjusted. Also, it would be appreciated to adjust the backrest head of the backrest, characterized in that an actuation or rotation of the adjusting 32 is made. Also regarding the adjusting wheel 32 a large number of secondary functions of a different kind could be set.
Finally is off 1 seen that the adjusting wheel 30 for non-slip and easy to dose handling on the outer circumference with individual grooves 38 or grooves or the like is provided. In addition, it can be seen that the adjusting wheel 32 with a corresponding knurling 39 is provided to a reliable and easy operation or rotation of the adjusting wheel 32 to enable.
In 2 is a schematic side view of the seat adjustment in one opposite 1 especially with regard to the other adjustment 26 . 28 illustrated alternative embodiment. Because the adjustment switch 10 . 12 in terms of their adjustment directions 16 . 18 . 20 . 22 . 24 to the embodiment of the seat adjustment according to 1 are substantially identical, the corresponding reference designation has been continued identically. An essential difference of the embodiment according to 2 is it that in the present case as an adjustment switch 26 . 28 two adjusting wheels 40 . 42 in the respective associated load-adjusting switch 10 . 12 are arranged completely integrated. In other words, the two adjusting wheels 40 . 42 designed and oriented so that these from the corresponding adjustment 10 . 12 be surrounded like a frame. Another difference is that in the seat adjustment according to 2 the two axes A of the respective adjusting wheels 40 . 42 transversely and in particular perpendicular to the essential extension direction of the respective adjustment switch 10 . 12 run. In other words, when turning the respective Verstellrades 40 . 42 Consequently, a rotation or adjustment (double arrows 31 . 33 ) of the respective adjusting wheel 40 . 42 which substantially parallel to the extension direction of the respective adjustment switch 10 . 12 runs. The two adjusting wheels 40 . 42 are also in too 1 analogous way with grooves 38 or knurling 39 Mistake.
In an identical way to the embodiment of FIG 1 are the as adjusting wheels 40 . 42 trained adjustment switch 26 . 28 Also provided here for setting secondary functions of the vehicle seat, which be already in connection with the Verstellrädern 30 . 32 according to 1 have been described.
Overall, it can be seen from the figures that by means of the respective first and second, designed as Hauptverstellschalter adjustment 10 . 12 a simple and safe to use manageable possibility is created to the seat cushion part and the backrest part of the vehicle seat in its main directions 16 . 18 . 29 . 22 . 24 to adjust. In addition, offers the respective, designed as a side adjustment switch adjustment 30 . 32 respectively. 40 . 42 a simple way for the seat occupant, especially secondary functions of the vehicle seat intuitively and easily detect and fine-tuned set.
