Abstract

The invention relates to a motor vehicle (K) having at least one seat (10-13), wherein the seat (10-13) or a component thereof is electrically adjustable by actuation of at least one operating element (100, 110, 120, 130). According to the invention, it is proposed that the electrical adjustability of the seat (10 to 13) or at least one component thereof be deactivated. In this way, an unauthorized or accidental adjustment of the seats can be avoided.

Description

The invention relates to a motor vehicle having the features of the preamble of patent claim 1.

Such the preamble of claim 1 forming motor vehicles with electrically adjustable seats are well known from the general state of the art. As a rule, each electrically adjustable seat has an adjusting switch assigned to it and sometimes also a so-called memory switch with which a user can individually store and retrieve a preferred sitting position.

This not only applies to the front seats, but is now increasingly found in rear rows of seats.

The type of possible adjustment is very diverse. Thus, a seat today comprises at least as essential components a seat cushion, a seat back and a headrest. Each of these components can sometimes be individually adjusted electrically for itself, with adjustment movements in the longitudinal, vertical and transverse directions, but also pivotal movements are conceivable.

As a further seat components lordosis supports, inflatable massage cushion and also connected to the seat belt height adjustments are also mentioned. The list is not exhaustive, other seat components are conceivable.

Adjustment switches for adjustable seats are not only arranged in the lateral area of the seat cushion, but are also partially found in a front or rear center console. Due to their easy accessibility, an unwanted or even wanton adjustment, especially by children, can not be ruled out.

From the prior art, the provision of a child safety, for example, against accidental opening of the door or against opening the rear window, well known.

For example, is from the DE 103 36 602 A1 an electromechanically controllable child safety device for a door lock of a motor vehicle known. The child safety device is temporarily deactivated by means of a monostable multivibrator, so that a passenger sitting in the rear of the motor vehicle can disembark without significant effort despite activated child safety lock.

The present invention is based on the object to improve a motor vehicle according to the preamble of claim 1 such that a greater control with respect to an adjustment of seats, especially by children, can be achieved.

This object is achieved with the characterizing features of claim 1. Advantageous embodiments or developments of the invention can be taken from the respective subclaims.

The invention relates to a motor vehicle with at least one seat, wherein the seat or at least one component thereof is electrically adjustable by actuation of at least one operating element.

It is proposed according to the invention that the electrical adjustability of the seat or at least one component thereof is deactivated.

In this way, unwanted adjustments, especially by children, can be excluded.

According to a first development of the invention, different rules for the treatment of an adjustment request for the seat or a component thereof are adjustable.

This allows a very good orientation to the needs of a user, especially a driver.

Preferably, the different rules via an operating menu of the on-board electronics are adjustable. In this way, the settings can be made very comfortable. For example, the operating menu can also be part of a central infotainment system with which various basic settings of the motor vehicle can be used to make audio, video, communication and navigation settings.

It is very useful if multiple electrically adjustable seats are present and the adjustability of either each individual seat, a group of seats or all electrically adjustable seats is deactivated.

In this way, the operation and also the ease of use can be better matched to the needs occurring in different driving situations. The deactivation of an adjustability of the driver's seat, however, is only effective for such adjustment requirements that are not initiated from the driver's seat or by the driver himself.

According to an advantageous embodiment of the invention, at least one rule is adjustable, according to the an adjustment request for an adjustable seat should always be performed, but an adjustment leads to an audible and / or visual warning.

This has the advantage that the driver retains control over the adjustments made, but passengers are largely self-sufficient in their settings.

However, it may be expedient that the acoustic and / or visual warning is connected to a possibility or is connected to make the adjustment performed undone.

For example, the driver may be made aware that a headrest of a rear seat seat has been swung forward. If the driver does not want to tolerate this for certain reasons, he may make use of the possibility of cancellation and confirm this on a suitable input device. Such an input device may be, for example, a touchscreen.

It is advantageous in this context, if the possibility of cancellation is offered only for a certain short time, so that the driver is distracted by adjusting the passengers as little as possible.

Alternatively, it may also be advantageous if at least one rule is adjustable, according to which an adjustment request initially leads to an audible and / or visual warning of the vehicle driver and the latter can reject or release the adjustment request.

In this way, the driver is given maximum control over desired adjustments to the seats.

It may be expedient if an adjustment or an adjustment request leads to an animation on a display unit.

In this way, a warning to the driver can be intensified, so that it detects much faster, which adjustment or which Verstellanforderung it is.

Preferred embodiments of the invention are illustrated in the drawings and will be explained in more detail in the following description. Here, the same reference numerals refer to the same, comparable or functionally identical components, with corresponding or comparable properties and advantages are achieved, even if a repeated description is omitted.

They each show schematically

1 an inventive motor vehicle with adjustable seats whose adjustability is deactivated, in a plan view,

2 the individual representation of an adjustable seat including its adjustable components,

3 the representation of an input menu, with the help of which different rules for the treatment of an adjustment request are adjustable, and

4 an exemplary animation as a result of an adjustment request or a successful adjustment.

First, on the 1 Referenced.

In the 1 is a motor vehicle K seen from above, which has electrically adjustable seats.

So are a driver's seat 10 , a passenger seat 11 , a rear left seat 12 and a rear right seat 13 electrically adjustable.

The electric adjustment of the front seats 10 . 11 can via adjustment switch 100 . 110 take place, which respectively on the outer sides of the seat cushion of the seats 10 . 11 are arranged.

The electric adjustment of the rear seats 12 . 13 via adjustment switch 120 and 130 which is on a rear center console 15 are arranged.

The rear center console 15 also has a touch screen 21 on, on the rear passengers through the settings are possible. For example, audio and video settings can be made. It is also conceivable that an adjustment request of a passenger also relates to a seat on which the passenger himself is not seated. For example, a passenger may be seated 13 wish that the seat 11 is moved forward to gain even more legroom.

From the figure is also a front center console 14 seen on the one armrest 16 and a shift lever 17 a transmission not shown are arranged.

Above the center console 14 is also one in the area of a dashboard touch-sensitive input and output unit 20 in the form of a touch screen.

Finally, there is an instrument cluster 18 indicated, which is in the primary field of vision of a driver behind a steering wheel 19 located.

Each of the seats 10 to 13 is equipped with a seat control unit SSG, which in turn in signaling connection with not shown controllable adjusting motors for various components of the seats 10 to 13 stands.

Likewise, the adjustment switches 100 . 110 . 120 and 130 signal-technically connected to the control units SSG. About the adjustment switch 100 . 110 . 120 and 130 initiated adjustment requirements are thus forwarded to the seat control units SSG, which can direct the desired adjustments in the ways of the mentioned electric motors.

The seat control units SSG are interconnected via a CAN bus C and with an operating module 22 connected by signal technology.

The operating module 22 located on an armrest inside the door panel of the driver's door. It includes several control switches, especially control switches 22a to 22e ,

The operating switches 22a to 22e are designed as a push-button and have, depending on the user-side default on a on the touch screen 20 callable operating menu, partly different functionality.

So the control switches can 22a to 22e For example, be assigned with the following functions:
control switch 22a : Deactivation or reactivation of an adjustment of the passenger seat 11

control switch 22b : Deactivation or reactivation of an adjustment for the rear left seat 12 ,

control switch 22c : Deactivation or reactivation of an adjustment for the rear, right seat 13 ,

control switch 22d : Joint deactivation or reactivation of an adjustment of the two rear seats 12 and 13 ,

control switch 22e : Complete deactivation or reactivation of all adjustment options with regard to the seats 10 to 13 as well as with regard to the windows associated with these seats.

On the passenger side, there are two control buttons in the area of the door interior trim 23 and 24 held, which are used to operate the associated window or additional lighting (not shown).

Based on 2 will now be exemplary of the rear, left seat 12 the seat components and their adjustment explained in more detail.

The seat 12 has a seat cushion 121 on, which is formed longitudinally and vertically adjustable or pivotable. With the seat cushion 121 is over a connection point 125 a seat back 122 connected. The seat back 122 is over an upper connection point 124 pivotally connected to the vehicle body. For example, the seat cushion 121 adjusted by electric motor in the longitudinal direction, so leads the backrest 122 due to the given kinematics at the same time a slight pivoting movement (see arrows).

Inside the seat back 122 is also a movable lumbar support 127 indicated, which is adjustable in height substantially.

Furthermore, there are several inflatable massage pillows 126 present, with which the seating position of a passenger in the broadest sense can also be changed.

Finally, on the seat back 122 a height and length adjustable and also swivel headrest 123 available.

Based 3 It will now be explained to what extent different rules for the treatment of an adjustment request for an adjustable seat or a component thereof are adjustable.

So is about the touchscreen 20 a menu can be called, in the embodiment, five different adjustment levels for the adjustment of adjustment requirements are adjustable.

In this case, a lowest setting level 0 can be selected, that of a rule 200 according to which any adjustment requirements are basically carried out. In this lowest setting level, therefore, there is no protection against misalignments.

In contrast, in a topmost adjustment level 4 a rule 204 after which any adjustment requests for a seat are ignored. On the adjustment level 4 thus a maximum adjustment is given.

On a setting level 1 is a rule 201 selectable, after an adjustment request though should be carried out in principle, but an adjustment leads to an audible and / or visual warning.

A driver thus receives a better overview of what is happening in his motor vehicle.

By means of a setting level 2, a rule 202 selected according to the supplement to the previous rule 201 the acoustic and / or visual warning is connectable with a possibility or is connected to make a performed adjustment undone.

As a result, the ability to control a driver is so significantly increased. Finally, via a setting level 3 a rule 203 are selected after an adjustment initially leads to an audible and / or visual warning of the driver and this can reject or release the adjustment request.

The input possibility for reversing a performed adjustment or also for the rejection or release of an adjustment request is visually and / or audibly output, the driver by manual input (for example, on the touch screen 20 ) but also by voice input can respond.

If, after a preferably predeterminable period of time, no reaction of the vehicle driver is detected, then the system logic at setting level 2 assumes that an adjustment carried out is not to be reversed.

At setting level 3, the system logic assumes that an adjustment request should be rejected, since this is a higher level of adjustment.

There are also other or different levels of adjustment conceivable. For example, a setting level can be selected according to which rule adjustment requests are only ignored when reaching or exceeding a preferably determinable speed (not shown) or when they reach or exceed the validity of other rules is only effective.

In order to inform a driver comprehensively and easily understandable about a performed adjustment or an adjustment request, it is conceivable that an adjustment or an adjustment request leads in addition to an animation on a display unit.

This is based on 4 shown. Here is the instrument cluster 18 indicated within which is a freely programmable display 180 located.

In the present case was from one on the rear, left seat 12 seated rear passengers one headrest 123 of the seat 12 relevant adjustment request via the adjustment 120 issued.

It is the adjustment level 3 with rule 203 activated.

On the display 180 a seat icon S is shown, which is divided into a seat cushion icon S1, a back icon S2 and a head support icon S3. In addition, an animation A can be seen with which the head support symbol S3 (possibly repeated) is moved forward to a position S3 '. The animation A may additionally be highlighted in color and / or by flashing.

In addition, a text box 181 in which the driver is informed about which seat it is, for example "rear seat left".

Alternatively or additionally, an overview graphic can also be provided 182 are displayed, in which the affected seat is highlighted visually (for example, by flashing and / or prominent color).

The driver now has the option of the adjustment request visualized by the animation A by pressing the control switch 22b release. He can also do this by voice input. If he does not react within a certain period of time, the headrest remains stationary 123 of the seat 12 in their original position.

Depending on the selected setting level, the control switches 22a until e assigns different functions.

For example, if the setting levels 0 or 4 selected, so can by pressing the control switch 22a until e are seated or seat group related respectively between the setting levels 0 and 4 are changed. The driver can thus, without in the selection menu described (cf. 3 ) have to go, quickly and easily activate an adjustment or deactivate again.

When one of the adjustment levels 1 to 3 is selected, the operation switches are used 22a to e for the reversal of adjustments or for the release of adjustment requirements.

It is of course conceivable that the selection of one of the setting levels 0 to 4 is not a flat rate for all seats 10 to 13 but separately for each individual seat is feasible. This can be selected in advance via a special settings menu (not shown).

The above-described settings or the deactivation of the adjustability of the seats is only possible when the ignition of the motor vehicle K is turned on.

The invention is not limited to the above embodiments. These were used only for general explanation of the essence of the invention. Rather, within the scope of its scope, the invention may assume other than the embodiments or forms described above. In this case, it may in particular also have features which represent a combination of individual features of the respective claims.
