Description

FIELD OF THE INVENTION

The present invention relates to a vehicle seat system for a rear row of seats in a motor vehicle and to a control device for such a vehicle seat system.

TECHNICAL BACKGROUND

The seat rows arranged behind the driver's seat and, if applicable, the front passenger seat of a motor vehicle are referred to as rear seat rows. This can in particular be a second or a second and third row of seats.

A seat in such a rear row of seats is referred to as a rear seat.

There are both manual and electrical adjustment functions for the rear rows of seats in motor vehicles.

For many types of motor vehicle, a requirement for the seats in a rear row of seats is to enable a so-called cargo position, in which the rear seat releases additional cargo space of the motor vehicle by folding down the seat back and / or the seat surface.

In the case of manually adjustable rear seats, an unlocking lever is usually provided for this purpose for actuating a locking fitting for folding down the seat back of the rear seat.

Electrically adjustable rear seats usually have two different positions for the seat back and / or the seat surface, namely a seat position in which an occupant can sit on the rear seat and a cargo position in which additional cargo space of the motor vehicle is released. Such rear seats are for example in the DE 198 36 060 B4 or in the WO 2004/060713 A1 described. However, these rear seats are not adjustable in terms of seating comfort.

There are also rear seats that are electrically adjustable in a comfort area to adapt the seating comfort. Such a rear seat is in the EP 0 260 631 A1 described. This rear seat can be moved in the longitudinal direction and inclines its seat back in a comfort area. Due to the design, this seat cannot be folded into a cargo position.

DE 102 09 759 A1 , US 2011/0 042 993 A1 , DE 10 2006 054 696 A1 , DE 10 2006 061 502 A1 , EP 1 375 254 A1 , DE 103 53 809 A1 and DE 36 09 690 A1 describe further electrically foldable vehicle seats and / or vehicle bench seats. DE 10 2007 026 184 B4 describes an adjustable vehicle seat that can be electrically controlled via a remote control. DE 10 2004 033 222 A1 describes a seat adjustment mechanism for folding a vehicle seat in and out.

SUMMARY OF THE INVENTION

Against this background, the present invention is based on the object of specifying an improved vehicle seat system for a rear row of seats of a motor vehicle and a control device provided for this, which enable simple adjustability between a comfort area and a cargo position of the seat back and / or the seat surface.

According to the invention, this object is achieved by a vehicle seat system with the features of claim 1 and / or a control device with the features of claim 26.

Accordingly, there is provided: a vehicle seat system according to claim 1 and a control device according to claim 26.

The idea on which the present invention is based is to provide both an adjustment in a comfort area and an adjustment in a cargo position by a motor, without this compared to a sole electrical adjustability in the comfort area or a sole electrical adjustability for folding into the cargo -Position additional controls are necessary.

According to the invention, the individual functions of the adjustment are therefore implemented via an operating logic of the actuating element. This advantageously makes a large number of switches, loops or levers obsolete in a rear seat or in a rear seat.

At the same time, the completely electrical adjustability improves the ease of use.

According to the invention, a vehicle seat system therefore has a small number of switches and / or buttons but nevertheless a large bandwidth of functionality. Operation is also more intuitive, convenient and simple. A user, in particular an occupant or passenger, is thus advantageously relieved.

Furthermore, an attractive design of the seat can also be achieved by a small number of switches / buttons according to the invention. In addition, the operating safety is increased, since incorrect operation is excluded.

A control device can be provided for the corresponding control of the rear seat. Alternatively, a connection to an external control device can be provided. A control device can therefore be understood to mean both a seat-internal control device and an external control device.

In the case of a control device inside the seat, it is preferably a control device with inputs and outputs as well as interconnections corresponding to the design. Furthermore, a computing device is preferably provided with a programming that maps the provided operating logic.

In the case of an external control device, this can in particular be provided integrated in vehicle electronics of a motor vehicle, for example in a so-called “on-board power supply control device” or “body control module”. However, an extra external control device can also be provided.

In the case of an external control device, a connection for the operating element and the rear seat, in particular a central plug for the entire seating system, is provided, by means of which a connection to the control device via an on-board network, in particular a central bus, can be established or in the assembled state.

A design of the control device can be both a software-based and a hardware-based design. The software-based design is, in particular, a program-based mapping of the operating logic of the vehicle seat system. The hardware design is in particular a corresponding input and output, circuit and power design.

In one embodiment, the rear seat is adjustable by an electric motor. Accordingly, a control device controls an electromotive adjustment of the rear seat.

In a further embodiment, however, a pneumatic and / or electro-hydraulic seat adjustment can alternatively or additionally also be provided. In this case, the control device controls a pneumatic or electro-hydraulic adjustment of the rear seat accordingly.

An operating element is to be understood as any type of human-machine interface by means of which an input can be made. It is preferably an operating element provided predominantly, in particular exclusively, for adjusting the rear seat, in particular an operating element arranged in a manner suitable for adjusting the seat. However, it is also conceivable to use an operating element for seat adjustment that can also be used for other purposes in a motor vehicle.

Advantageous refinements and developments emerge from the further subclaims and from the description with reference to the figures of the drawing.

All of the features of the design of a control device designed to actuate the rear seat, which are shown below in relation to the vehicle seat arrangement, also represent features of the design of a control device according to the invention for such a vehicle seat arrangement. Features relating to the design of the control device can therefore be combined with the design of the control device according to the invention.

According to one embodiment, the operating element is provided directly on the rear seat. Thus, an intuitive operation for adjusting the rear seat is realized.

In a further development, additional control elements are provided, for example in the grip area of a driver of a motor vehicle, on a further seat, on a door of the motor vehicle, on a center console of the motor vehicle and / or in a luggage compartment of the motor vehicle.

According to one embodiment, the operating element is designed as a toggle switch with a first button and a second button. The first button is preferably a short button and the second button is a long button. Conversely, however, the first button can also be designed as a long button and the second button as a short button. An equally long design of the two buttons is also possible. The length of a button is characterized by the distance between a terminating edge of the button and a tilting axis of the toggle switch. With a toggle switch, a single operating element advantageously has two operating directions. The number of control elements can thus be reduced.

According to one embodiment, a control device for controlling the rear seat is designed to process an actuation of the first pushbutton as a first predetermined input. Thus, when the first button of the toggle switch is actuated, the rear seat is actuated for adjustment in the comfort area. In particular, an adjustment in the comfort range is controlled by one adjustment step. An adjustment step in particular represents the smallest unit of an adjustment in the comfort range, for example an adjustment by one notch of an actuating drive.

According to a development, the control device is designed to process a simple actuation of the second button as a second predetermined input.

According to an alternative development, the control device is designed to process a simple actuation of the second button as a first predetermined input for adjustment in the comfort range with several adjustment steps at once. Accordingly, the control device then controls the seat for adjustment in the comfort range with several adjustment steps. As an alternative or in addition, an adjustment with an increased adjustment speed can also be activated.

According to an advantageous development, the control device is designed to process a double or triple actuation of the second pushbutton as a second predetermined input. Two different functions can thus advantageously be controlled with a single button.

According to one embodiment, the rear seat has an electrically adjustable through-loading, wherein the control device is designed to control the through-loading in response to a third predetermined input in order to fold down or to stand up. The third predetermined input is, in particular, a double actuation of the second button. In this case, the control device is designed to process a three-time actuation of the second pushbutton as a second predetermined input. In a further embodiment, the third predetermined input is a triple actuation of the second button. In this case, the control device is designed to process a double actuation of the second pushbutton as a second predetermined input. Thus, three different functions of the vehicle seat system can be controlled with a common button. In both embodiments, multiple occupancy of an operating element by operating logic advantageously reduces the number of operating elements.

According to one embodiment, the operating element is designed as a single button. This also advantageously reduces the number of buttons.

According to an advantageous embodiment, a control device for controlling the rear seat is designed to process a simple actuation of the button as the first predetermined input.

According to a development, the control device is also designed to process a permanent actuation of the button for longer than a first predetermined period of time and / or a double actuation of the button as a second predetermined input. The first and the second predetermined input are advantageously implemented with a single button by means of such an operating logic.

According to one embodiment, the control element comprises a remote control. This is preferably a removable remote control provided for integration in a luggage compartment of a motor vehicle. Another embodiment is a remote control that can be integrated as a software module in a mobile radio device, in particular a smartphone. Alternatively or additionally, a remote control integrated in a radio vehicle key is also conceivable.

According to one embodiment, the control element comprises a touchscreen that can be occupied by control panels. A control device for controlling the rear seat is designed to control the rear seat for adjustment in accordance with an input made on the touchscreen. A touchscreen can be provided directly on the seat. In particular, it is possible to operate the rear row of seats directly on the seat with a touchscreen. This represents in particular a user interface that is flexibly adapted to the respective position of the rear seat. Furthermore, buttons on the touchscreen, so-called softkeys, for the direct control of different seat positions, for example the cargo position, a rearmost seat position in the comfort area, a lounger, can be used, for example Position, an entry and exit position or the like. This functionality can be used, for example, to make it easier for passengers to board at the push of a button. Several touchscreens can also be provided for different locations in a motor vehicle for controlling the vehicle seat system for the rear seat row (s). For example, a touchscreen that can be operated from the driver's or front passenger's seat can be provided with a corresponding graphical user interface for operating the vehicle seat system of the rear seat row (s). As an alternative or in addition to a touchscreen, the vehicle seat system can also be operated via additional buttons in the driver or front passenger area, for example on the steering wheel, in the center console or in the door. The buttons (hard keys) can also have one or more buttons for different seat positions. In particular, multiple switches / buttons or touchscreens can be available that can be reached from each seat of a motor vehicle, so that the rear seat can be adjusted from different seats, in particular from each seat.

According to one embodiment, the rear seat can be adjusted in the longitudinal direction by a motor educated. Furthermore, the control device is designed to adjust the rear seat in the longitudinal direction in the event of a fourth predetermined input on the operating element. The fourth predetermined input is, in particular, a permanent actuation of the operating element for longer than a second predetermined period of time. Up to four functionalities of the vehicle seat system can thus advantageously be operated with a single operating element.

According to one embodiment, an entry / exit switch is provided on the rear seat. This is arranged to be accessible from a further row of seats arranged behind the rear seat. The further row of seats arranged behind the rear seat is in particular a third row of seats. A control device for actuating the rear seat is designed to actuate the rear seat for an adjustment to assume an entry / exit position when the entry / exit switch is actuated. In the entry / exit position, the seat back of the rear seat in particular is folded forward. The entry / exit position can also be the cargo position. In particular, the entry / exit switch is provided in addition to the control element. For example, the entry / exit switch is a single button.

According to one embodiment, a sensor system is provided in addition to the control element, a control device for controlling the rear seat being designed to control the rear seat as a function of a sensor signal output by the sensor system. The operating logic of the vehicle seat system is thus advantageously supported by the sensor system.

According to one embodiment, the sensor system includes a seat occupancy sensor that monitors the rear seat. The control device is designed to trigger the rear seat to fold down only when the sensor signal of the seat occupancy sensor indicates that the rear seat is free. A folding down of the rear seat is thus advantageously avoided when the rear seat is not free, for example when a person is sitting on the rear seat or when there is an object on the rear seat.

According to a development, the control device is designed to directly adjust the rear seat to take the folded cargo position or to stand up from the folded cargo position when the sensor signal of the seat occupancy sensor indicates that the rear seat is free when an input is made on the operating element. In this case, the combination of the input on the operating element and the sensor signal indicating the vacant rear seat represents a first predetermined input. A situation-adapted operating logic, in particular one adapted to an occupancy state of the rear seat, is advantageously provided.

According to a further development, the control device is designed to directly control an adjustment in the comfort range when an input is made on the operating element, if the sensor signal of the seat occupancy sensor indicates that the rear seat is occupied. A simplified operation of the adjustment in the comfort area is thus advantageously made possible when a person is sitting on the rear seat. In this case, the combination of the input on the control element and the sensor signal indicating the occupied rear seat represents a second predetermined input. Here, too, a situation-adapted operating logic, in particular one adapted to an occupancy state of the rear seat, is advantageously provided.

According to one embodiment, the sensor system is designed and designed to detect a pressure applied by an occupant sitting on the rear seat and to forward a corresponding pressure-dependent signal to the control device. The control device is designed to carry out an adjustment of the rear seat adapted to the pressure in order to adjust the rear seat in the comfort area.

The sensor system is preferably designed and designed to detect the pressure quantitatively. Furthermore, the control device is preferably designed to carry out an adjustment of the rear seat that is quantitatively adapted to the pressure. In response to the first predetermined input, the seat thus rests against an occupant seated on it. A pressure indicating the seated position of the occupant is detected by means of the sensor system. Accordingly, the rear seat adapts to the adjustment and stops when a predetermined pressure is reached.

Alternatively or in addition, the control device can be designed to initially actuate the rear seat in response to the first predetermined input or to a further predetermined input in order to adjust it to a rearmost position in the comfort area. In particular, the rear seat can remain in this rearmost position for a predetermined short period of time. Meanwhile, the occupant can take a desired position. The rear seat is then moved towards the occupant for adjustment and is stopped depending on a pressure detected by the sensor system.

The adjustment is preferably stopped when the seat provides optimal support for the occupant. The sensor system can also be designed and configured to include a weight on the rear seat 3 seated occupants quantitatively capture. In this case, the pressure predetermined for detecting optimal support for the occupant is dimensioned to be adapted to the determined weight. In addition, the rear seat can be locked in the position it has then assumed.

In one embodiment, the control device is coupled to a pre-crash detection device of a motor vehicle. In this case, the control device is designed to block the functionality of the seat adjustment based on pressure detection in the event that the pre-crash detection starts, in order to avoid incorrect adjustment.

According to a further development, the sensor system comprises a pressure mat integrated into the rear seat. This is preferably a pressure mat integrated into a seat back of the rear seat. As an alternative or in addition, a positioning force sensor and / or a drive current meter integrated in an adjustment drive can be provided, a measured positioning force or a measured drive current being dependent on the pressure in each case.

According to one embodiment, the sensor system is designed and designed to detect a charge status of a luggage compartment arranged behind the rear seat and to forward a charge status-dependent signal to the control device. The control device is designed to trigger an automatic folding of the rear seat into the cargo position when a predetermined capacity limit of the luggage compartment is reached when the sensor signal of the seat occupancy sensor indicates that the rear seat is free. The seat is therefore advantageously automatically folded into the cargo position if this is required and possible depending on the situation.

According to a further development, the sensor system is also designed and designed to detect a charge state of a swivel area required for erecting or adjusting the rear seat. The control device is designed to control an uprighting or adjustment of the rear seat in the swivel area only when the swivel area is free. In this way it can advantageously be avoided that cargo is unintentionally damaged when a rear seat is set up. It is also conceivable that if the cargo is only partially in the pivoting range of the rear seat, the range of adjustment is merely restricted in an adapted manner. For example, in this case the seat back can only be in a vertical position when it is raised from the cargo position. Furthermore, in one embodiment, the sensor system can advantageously be used to automatically detect possible misuse or misuse that may damage the rear seat and to avoid it by stopping an adjustment. In this way, an injury to the passengers can advantageously also be actively prevented.

According to a preferred development, the sensor system includes a camera system for monitoring the charge status of the luggage compartment. The camera system is optionally or additionally provided for monitoring the charge status of the swivel area.

According to one embodiment, a luggage compartment operating element that can be installed in the luggage compartment is provided in addition to the operating element.

In one embodiment, the rear seat is provided such that it can be controlled in response to inputs made on the luggage compartment operating element in the same way as to inputs made on the operating element. There is therefore advantageously a consistent operating logic for operating the vehicle seat system.

According to an alternative or additional embodiment, a control device for controlling the rear seat is designed to use a fifth or further predetermined input on the luggage compartment control element to control different rear seats individually for an adjustment to assume the folded cargo position or to get up from the folded cargo position . A plurality of rear seats can thus advantageously be operated individually with one, in particular a single, luggage compartment operating element for the additional freeing up of storage space.

According to one development, the vehicle seat system has a multi-part rear bench with several rear seats. The control device is designed to process a sustained actuation of the luggage compartment control element for a third predetermined period of time as a fifth predetermined input and then to control a first rear seat for an adjustment to assume the folded cargo position or to stand up from the folded cargo position. In addition, the control device is designed to process a continued actuation of the luggage compartment control element for a fourth predetermined period of time as a sixth predetermined input and then to control a second rear seat for an adjustment to take it up or to stand up from the folded cargo position.

According to a further development, at least one of the rear seats has an electrically adjustable through-loading, wherein the control device is designed to fold down or erect the through-loading in response to a seventh predetermined input. In particular, the seventh predetermined input is a continuous actuation of the Luggage compartment control element for a fifth predetermined period of time. Preferably, the fifth predetermined time period is shorter than the third predetermined time period. Thus, when the luggage compartment control element is continuously operated, the through-loading is first folded down and then the first and second rear seats are folded down. Both the rear seats and a through-loading of a rear bench can thus advantageously be operated by means of the luggage compartment control element.

Upon actuation of the luggage compartment control element, which is designed, for example, as a toggle switch, the control device is designed in particular to initially control the through-loading for folding down when the luggage compartment control element is pressed continuously, for example a first button of a toggle switch arranged in the luggage compartment, and then again Actuation, for example, only to drive the 40% part of a 40 to 60% split rear seat to fold down. If you continue to press the button, the 60% part of the split rear seat is activated to fold down.

Preferably, the control device is also designed to actuate the rear seats and the through-loading of the rear bench again for setting up when the second button of the toggle switch is actuated. This can be provided either in the reverse order of folding down or with both rear seats and the through-loading at once.

In a further embodiment, the fifth to seventh predetermined input can also be implemented in each case for a predetermined number of times the first button of the toggle switch of the luggage compartment control element is actuated. In this case, the luggage compartment operating element has a different operating logic than the operating element. For example, the control device can be designed to control the loading door for folding over when the first button is pressed once or for the first time, and to activate the 40% part of the rear seat to fold down when the first button is pressed twice or a second press within a predetermined period of time. and when the first button is pressed three times or within a predetermined period of time, the 60% part of the rear seat is actuated to fold down.

According to one embodiment, a row of seats located in front of the rear seat has a front seat which is also designed to be adjustable by a motor. A control device for controlling the rear seat is designed to initially control the front seat in response to the second, fifth or sixth predetermined input for an adjustment into a release position in which a swivel range required for folding or erecting the rear seat is released. For example, a seat back of the front seat can be set upright and / or the front seat can be adjusted forwards in the longitudinal direction. Furthermore, the control device is designed only afterwards to control the rear seat for an adjustment in order to assume the folded cargo position or for erecting it from the folded cargo position. This advantageously prevents the rear seat from colliding with a front seat when it is folded down into the cargo position. In particular, the front seat can then be actuated to automatically resume its previous position.
