Description

The The invention relates to a switching device for actuating the Adjustment of a vehicle seat, with several adjustment are arranged in both seat back and seat cushions, and each Adjustment at least one operating element for actuating the same is assigned, according to the preamble of claim 1.

switching devices to operate the adjusting elements in vehicle seats are widely known. The each adjustment does not affect by far only the tilt adjustment of the backrest or the front and Rückwärtsbewegbarkeit the seat cushion area, but have both seat back and seat cushion of the vehicle seats in each case a plurality of adjusting elements, which also the contour the seat or make the seat back changeable.

The Position as well as the contour of the vehicle seats are usually included Start of the journey by the respective driver. He chooses at least a matching contour and seat adjustment. By the arrangement several adjustment per seat element, so per seat back or Seat cushion, this is an individual adjustment of the seat contour as well the seating position possible.

frequently are and have been for this used mechanical lifting, crank or knob devices. To make adjustment easier and quicker, are mechanical actuating means often by electrical actuating means replaced.

at the enterprise longer Rides, however, it often happens that you also depend on the travel time while the ride makes Sitzpositions- or seat contour adjustments. Done this exclusively mechanically, so leads this because of the corresponding expenditure of force to an unfavorable Distraction of attention, especially of the driver.

The Use of electrical actuators already helps this deficiency from. By electrical actuating means of the force is almost negligible and also the attention remains essentially on the road directed.

The Question of the placement of the switching elements or the operating elements is therefore not just a matter of comfort, but also also a question of security. In this respect also plays the logical Interaction of the controls a relevant role, whether this attract the attention of the driver or without distraction from the traffic easy to operate due to its logical and functional placement are.

From the DE 195 34 660 C1 is a seat adjustment known in which a plurality of seat adjustment are provided. For this purpose, the electrical control of the individual adjusting elements is guided to a common operating element. The disadvantage here is that when operating the individual adjustment elements on a common control of the driver is relatively easily distracted because appropriate multi-functional normally refer to many switching functions on a switching element.

From the DE 31 42 833 C2 a seat adjustment is known, wherein the adjusting elements consist of several pressure chambers. The individual pressure chambers are also controlled here by a common operating element in the form of a pressure control valve. That is, even here come a single control to a variety of individual adjustment to what a corresponding complicated operation requires.

From the DE 28 36 004 C2 is a Sitzverstellanordnung known, in which case each seat element, ie backrest and seat is assigned to each control element. Here, the driver already has the ability to recognize by pressing keys, whether he pressed the correct control element in the desired adjustment or not. Nevertheless, a logical splitting of the controls only in the seat and backrest is then not sufficient if several adjustment per seat and backrest are provided. This creates the same problem as described above.

From the DE 41 37 888 A1 is a Sitzverstellanordnung known in which a plurality of adjusting elements are arranged both in the seat, as well as in the backrest. In this case, each adjusting element is associated with a respective individual operating element. These controls are arranged in direct accordance with the position of the individual adjusting elements. The disadvantage here is on the one hand that the individual controls are relatively far apart by the quasi-miniaturized positioning in replica of seat and backrest and are hardly accessible with regard to the back even in a sitting position, especially while driving.

From the DE 39 04 771 C1 such a control arrangement is shown in miniaturized Sitzkontur way. That is, the individual controls are placed anywhere within reach of the driver's seat so that they represent the seat contour miniaturized. That is, the individual controls are not far apart.

From the DE 196 31 454 C2 a vehicle seat with a seat plate and a backrest is known, wherein adjustments of the backrest and the seat plate can be carried out via a plurality of operating elements. The controls are located immediately adjacent to each other. These controls allow the adjustment of an individual element of the vehicle seat. In addition, a further adjacent to the other controls control is arranged by the operation of the entire vehicle seat can be adjusted in terms of a stored ergonomics setting.

From the DE 39 24 292 C1 is a switch group for remote control of an adjustable via actuators vehicle seat known, with a plurality of controls are arranged on a step-shaped center console of a vehicle. The controls can be operated so that sub-elements of the vehicle seat can be set separately. Another separate changeover switch is provided to select two different function programs.

Another switch device for actuating sub-elements of a vehicle seat is in the EP 0158 607 A1 disclosed. A plurality of operating elements is arranged on a fixedly positioned base unit.

In addition, the reveals DE 43 31 663 C1 a position and contour adjustable vehicle seat having a control switch group with a plurality of controls.

In addition, the reveals DE 39 33 561 C1 a control device for controlling actuators for the adjustment of a motor vehicle seat, wherein an actuating element is divided into two subregions, which can be moved independently of each other.

Of the present invention is based on the object, a switching device to operate the adjusting elements in vehicle seats of the generic type, to improve that a variety of functions possible, but the controls are logically placed and interconnected such that in a variety of functions and the control of a variety individual elements nevertheless the operation of the same of higher-level operating functions is separated.

The Asked task is in a switching device for operating the Adjustment of a vehicle seat of the generic type according to the invention the characterizing features of claim 1 solved.

Further advantageous embodiments of the invention are specified in the dependent claims.

The Essence of the invention is that the individual per seat back and per seat multiple arranged adjustment for each one individually controlled are, but also superior Functions like presetting or deferring the sitting position, or height adjustment or seat tilt position thereof are independently or superimposed operable. The logical link the individual switching functions or operating functions are the same selected that these always self-explanatory and thus do not attract the attention of the driver.

For this For example, are the majority of controls for each Adjustment of the seat cushion turn on a larger operating group element arranged. actuated Now the individual controls, which on the control panel element are arranged, so adjust only the individual adjusting elements for example, in the seat cushion in a proportional or parallel Way to the operator actuation path. actuated Now you the control group element, for example, by or Pushing back, So this movement or this operation is independent of the operation the individual adjusting elements, and the seat then moves in the corresponding Way forward or back. The same applies the backrest in a similar way.

It can also superimposed Movements performed be such as the lifting of the front adjustment in the seat cushion and the simultaneous retraction of the entire seat.

On In this way, a variety of functions are possible, but they are all self-explanatory. by the corresponding logical placement as operating single element or as a control group element.

Further Embodiments are that each control group element independent of the control elements arranged on it by turning, tilting or pushing the control group element can. The actuation directions The control group elements generate equivalent actuation paths on the seat back or seat cushions. You could say the appropriate one Movement of the individual controls generate proportional movements the associated adjusting element.

In Another advantageous embodiment of the invention are the individual Operating elements are arranged on the operating group elements or interconnected with them, that superimposed activity are possible by Einzelverstellelementen the seat back or the seat. What is meant here is that one For example, an operating element for the actuation of the front adjusting element of the seat cushion in the hand and pulls upwards accordingly or rotates, at the same time on the said control a superimposed additional exertion of force so applied that pushes the control group element backwards. In total one wants in this case then achieve that the front adjusting element in the seat cushion, for example, makes an upward movement during the also the entire seat by an appropriate amount to the rear is driven. That way you can most diverse superimposed Movements are generated, which by the inventive design and placement of the controls and control panel elements is favored.

The The invention is illustrated in the drawing and described in more detail below.

The illustration shows two control group elements 10 . 20 that are assigned to a vehicle seat and on which individual controls 11 . 12 . 13 respectively. 21 . 22 . 23 are arranged. The individual adjusting elements 1 . 2 . 3 respectively. 4 . 5 . 6 within the seat cushion or within the backrest are only indicated, because in this case the following applies. The representation of the flat control group element 10 represents in its outer shape, the seat cushion of the vehicle seat. In the places where distributed accordingly controls 11 . 12 . 13 on the control group element 10 are arranged, also within the vehicle seat cushion, the adjusting elements 1 . 2 . 3 arranged. In this respect, the grouping of the individual operating elements on the operating group element is, so to speak, proportional.

The upright with a slight tilt control group element is grouped in the same way proportional to the adjustment 4 . 5 . 6 inside the backrest of the vehicle seat. The controls 11 . 12 . 13 respectively. 21 . 22 . 23 are reduced in terms of their Sitzlehnen- or Sitzkisszuuweisung only in order to have all functions in reach handy proximity and bring the driver even with an adjustment while driving not in a dangerous seating position. On the basis of the illustrated arrows, it can be seen in which directions the operating group element of the assigned seat cushion surface is movable, namely forward and backward, in order to move the vehicle seat as a whole in a corresponding manner, and up and down to adjust the seat height. On the operating group element for the seat cushion three controls are arranged, which are rotatable in the manner shown. With a corresponding rotational movement in the direction shown, a proportional lowering or lifting movement of the corresponding adjusting element is generated in the seat cushion. The front operating element operates the front adjusting element in the seat cushion, the middle operating element adjusts the middle adjusting element in the seat cushion and the rear operating element also adjusts the rear adjusting element in the seat cushion.

The same applies to the operating group element of the backrest. As shown here, the operating element is rotatable as a whole, by what is meant by this the inclination of the backrest is adjustable. On the operating group element of the backrest Then again three individual controls are arranged, the corresponding proportionally distributed adjusting elements in the backrest actuate. The lower control is rotatable and causes a corresponding Adjustment of the lower adjusting element in the backrest. The middle control adjusts the corresponding middle adjustment in the backrest and the upper control then adjusts the corresponding upper Adjustment element in the backrest. Also this can be overlapping Movements are generated by, for example, simultaneously one of the controls and a total movement of the control group element generates a correspondingly proportional movement of the backrest.

By this inventive arrangement of Controls on according to the invention control group elements are superimposed movements self-explanatory executable without that Attention of the driver even while the drive over fee is claimed. This arrangement thus serves on the one hand the increased comfort service, and increase the driving safety.
