Description

The The invention relates to an adjustment switch arrangement for seat adjustment, especially for a motor vehicle, with the mentioned in the preamble of claim 1 Features.

It is known seats, in particular motor vehicle seats, in various versions to use and the motor vehicle seats according to the associated adjustment with as possible easy to handle operating options equip.

modern and comfortable motor vehicles provide in the front seats and Hintersitzanlagen mittennreile a number of adjustment at.

such Motor vehicle seats usually have a seat part and a backrest part on, by means of several actuators relative to each other and relative to the seat base held on the vehicle floor are adjustable.

Known Motor vehicle seats have the following according to the state of the art adjustment on. The seat part is, for example, with a device for height adjustment, Tilt adjustment, seat depth adjustment and seat length adjustment fitted. The backrest part has, for example, a device for backrest adjustment, backrest head adjustment and one of the standard height adjustment a headrest on. Furthermore, the backrest part in modern and especially from the luxury class known motor vehicles equipped with at least four-way lordosis, the above has its own lumbar adjustment device.

In addition are Today different concepts are known, which are particularly relevant to the comfort requirements the motor vehicle user adapted kinematics.

Especially in motor vehicle seats, in which the seat - ie seat part and backrest part - as a seat cushion in a seat carrier accomplished is, are particularly good, adaptable to the motor vehicle user Settings.

From the DE 199 51 625 C2 is a motor vehicle seat is known, which has such a seat cushion, which has a seat and a pivotally connected thereto backrest, wherein the seat and the backrest for Lageverstellen the seat support on a seat support are kept adjustable and fixed, whereby the back tilt of the backrest at a fixed seat angle between Backrest and seat by pivoting the seat support is adjustable relative to the seat support, and the seat tilt of the seat is fixed in the seat longitudinal direction articulation point of the seat on the seat support by pivoting the seat relative to the backrest.

The Seat tilt adjustment is performed by a device, an actuator, which is integrated in a pivot joint between the seat and backrest part. A seat tilt adjustment is also by a linear actuator executable. The linear actuator is at in the seat longitudinal direction fixed articulation point of the seat on the seat support Swiveling the seat relative to the backrest part adjusted.

The back angle the backrest part is done essentially as a forced tour at the established seat angle between the backrest part and seat through Swiveling the seat support relative to the seat support.

A similar seat adjustment with associated actuators according to the DE 199 51 625 C2 is from the DE 198 53 156 A1 removable. To adjust the seating position actuators are provided, which engage the underside of the seat part. The seat part - as well as the backrest part of the seat pivotally connected thereto via a hinge axis - is guided in a positive guide, which is designed as a sliding guide. Both the seat part and the backrest part are each guided at a distance from the hinge axis with a guide axis in a guide or slide track. While the guide rail associated with the seat part extends in a circular arc in the direction of travel upward, the guide axis of the backrest part is guided in a direction opposite to the direction of travel upwardly inclined linear guideway. The seat part and the backrest part are each held about their guide axis or guide pin rotatable in their guideways. While by means of an actuator, the inclination of the seat formed from the seat part and backrest part changed overall and thus the inclination angle of the backrest part can be adjusted, with the help of the other actuator, the angle between the seat and backrest part adjustable.

The Actuators that generate the actuating movements are about one Release switch can be activated and controlled by body position detectors.

The control via body position detector is very expensive and looks like the document DE 198 53 156 A1 always an adjustment in conjunction with a weight sensor before. From today's technical point of view, a weight sensor, which is used under concrete, always different conditions, only under extremely high To achieve costs. This represents a major disadvantage of the known solutions. It is therefore desirable to have a solution that makes it possible to combine the operation of the known adjustment options and the illustrated known kinematics of the prior art and can take on a variety of other functions.

To belong to these functions furthermore retrievable memory functions, which usually a certain Vehicle users are assigned. The memory-fuctions are through Switch in control arrangements within Verstellschalteranordnungen manufactured, their operation an automatic adjustment of a previously stored seating position entails. A modern and elaborately designed motor vehicle seat has usually several storable seating positions available.

Further Functions include the adjustment of the front seat and a rear seat over a and the same operating arrangement and the integration of a lordosis device.

Operating arrangements, which realize a number of functions of a motor vehicle seat are already known. Thus, there are operating arrangements in which the Actuators can be actuated separately from the user. By pressing the the actuator associated actuators and by pressing the the backrest part associated actuators, the user can the motor vehicle seat adjusted so until him the relative position of the seat part and Backrest part appears comfortable. To operate the adjusting drives are each vehicle seat several actuation switch assigned by the user to perform controlled positioning movements mostly operated one after the other become.

The Previously known motor vehicle seats are especially for inexperienced users only with a greater effort to use.

It There is therefore the task of a Verstellschalteranordnung for a Motor vehicle seat of the type mentioned above, in the desired Functions of the vehicle seat can be integrated and the particular comfortable and easy to handle.

These The object is achieved by an adjusting switch arrangement with the in the claim 1 mentioned features solved. Due to the fact that the adjustment of the motor vehicle seat via a Joystick takes place, the directions of movement of at least a first and associated with the second actuator is an adjustment created in which the kinematic possibilities of the seat and the control of the associated Actuators independent of body position detectors or the like are feasible. A weight sensor for controlling the actuators will not more needed. At the same time, additional functions can be assigned to the joystick in a weight-sensing controlled Verstellphilosophie not can be integrated. The control by joystick is a special simple type of control, through which a complex technique for body position determination can be waived.

In preferred embodiment of the invention is the joystick at least assigned a first and second direction of movement; at least one predominantly running transversely to the direction of travel first movement in the x-direction and one predominantly along the direction of travel of the motor vehicle in the y-direction executable second movement.

Everyone Movement direction is assigned to an actuator. It is quite conceivable, that at a direction of movement between the x and y direction, both associated actuators simultaneously can be controlled, insofar as a simultaneous control by the existing controlled kinematics is executable and executable should and such operation for the user makes sense.

essential to the invention and a first embodiment of the invention is the control of the Joysticks in a substantially x-direction. This will be the first Steering drive when the joystick moves transversely to the direction of travel driven. The activation of the first actuator causes that the back tilt of the backrest part with fixed seat angle α between Backrest part and seat the seat part only by pivoting the seat part relative to the seat carrier is adjustable. Here are the seat part, especially the Seat, and the backrest part by shifting the seat part in forced tours, the so-called scenes. Seat and backrest part are to each rotatable and movable over Linkage points on the seat carrier held. The constant angle α becomes through the area the seat part and the backrest part surface of the Backrest part educated.

In a further embodiment of the invention, when controlling the joystick in a substantially y-direction, along the direction of travel, the second actuator can be controlled. By this control via the joystick is the seat tilt of the seat part in a seat longitudinal direction. fixed pivot point of the seat part on the seat support by pivoting the seat relative to the backrest part adjustable. It can be achieved with the seat at a comparatively short adjustment a large Rücklegeigungsveränderung. While the back backrest part (seat cushion) is displaced in its forced operation of the backdrop, the seat part rotates by changing the enclosed between the seat of the seat part and the backrest part surface angle α to its fixed in the seat longitudinal direction of articulation point of the seat part on the seat support.

In Another preferred embodiment of the invention are the directions of movement the joystick other actuators for adjusting the seat assignable. The assignment of the first directions of movement remains in the x-direction or the second direction of movement of the adjusting switch arrangement receive. The respective direction of movement are, however, by switches assigned other actuators and thus new adjustment options.

Prefers is that through a lordosis switch a lordosis device becomes activatable. After switching, the movement of the joystick in essentially the x direction, an up and down of the lordosis device causes. For this purpose, a third actuator is controlled by the joystick. Accordingly takes over a fourth actuator a forward and backward lordosis of the lordosis device when the joystick is moving substantially in the direction of travel in the y direction.

to complement Further preferred embodiments of the invention are possible in which the movement directions x and y a height and longitudinal adjustment of the entire Seat can be assigned. Switching is done by a switch height / length adjustment seat. The movement following the joystick logically, becomes in the second direction of movement in the y-direction, which runs in the main direction of travel, the longitudinal adjustment of the seat over executed a sixth actuator. The first direction of movement of the joystick in a substantially x direction becomes one height adjustment device and one for that arranged fifth Assigned actuator. Of course, this assignment not compelling the directions, however, it will follow as much as possible equivalent directions of joystick and to be executed Movement of the seat.

Further is preferred, the y-direction of movement of the joystick along the Direction of travel a joint tilt adjustment of the backrest part against the Seat part by an arranged joint between backrest part and seat part to assign. For this purpose, by the Verstellschalteranordnung first of Switched joint tilt adjustment actuated and then the Joystick moved back and forth in essentially y-direction, which causes the backrest across from the seat part by means of a seventh actuator, which is on the joint acts, makes you swivel.

Ultimately it is an inventive feature the Verstellschalteranordnung that they are a changeover passenger seat or switch rear seat has. Its operation causes the movements of the joystick on the analog actuators the passenger seat or a rear seat act and there the same, as just described functions cause.

A rear adjustment to the initial function tilt adjustment backrest part or seat part takes place through the switch inclination adjustment, which in turn is the first and second actuator can be controlled.

Further preferred embodiments of the invention will become apparent from the others, in the subclaims mentioned features.

The Invention will be described below in embodiments with reference to FIG associated Drawings closer explained. Show it:

1 a perspective view of a motor vehicle seat with its adjustment and

2 a schematic Verstellschalteranordnung, in particular a joystick, and associated switches.

1 shows the motor vehicle seat 10 , the one backrest part 14 and a seat part 12 having. The backrest part 14 and the seat part 12 are in a seat carrier 18 arranged. This provides the backrest part 14 and the seat part 12 a kind of seat cushion backrest part 14 or seat part 12 dar. The backrest part 14 has an integrated headrest. The seat part 12 and the backrest part 14 , which may each have a plurality of segments are on their sides facing each other via a freely arranged pivot joint 16 connected with each other. The well-known swivel joint 16 is in 1 not shown in detail.

For adjusting the seat part 12 and the backrest part 14 These are on the seat support 18 adjustable and lockable. The seat carrier 18 is formed like a frame and preferably on both sides of backrest part 14 and seat part 12 arranged. Both, backrest part 14 and seat part 12 , are each at articulation points 42 . 44 in scenes 48 . 50 kept rotatable and movable. The backrest part 14 is from the articulation point 44 in the scenery 50 rotatable and movable, while the seat part 12 at the point of articulation 42 in the scenery 48 is held and guided rotatable and movable. The guide of the seat part 12 and the backrest part 14 in the wings 48 . 50 is preferably also on both sides in the seat support 18 ,

The back tilt of the backrest part 14 is at a fixed seat angle α (α = constant) between backrest part 14 and seat of the seat part 12 solely by pivoting the seat part 12 relative to the seat carrier 18 adjustable. This process the seat part 12 , in particular the seat, and the backrest part 14 by shifting the seat part 12 in her forced tours in the wings 48 . 50 , Retaining the seat angle α move backrest part 14 in a direction of displacement D with rotation of the articulation point 44 in one direction of rotation 54 on the axis of rotation B and the seat part 12 in a direction of displacement E. The inclination of the backrest part 14 is thus adjusted and the constant angle α is always through the seat of the seat part 12 and the backrest part surface of the backrest part 14 educated. This adjustment movement is through a substantially in the y-direction 26 executed movement in a second direction of movement 22 - a back and forth of a joystick 60 - Be effected within the Verstellschalteranordnung invention, by a first actuator 32 for tilt adjustment of the backrest part 14 is activated. The joystick 60 is schematic in 2 shown.

When moving the joystick 60 in a substantially x-direction 24 , the first direction of movement 20 transverse to a direction of travel 62 , will not be the first actuator 32 but a second actuator 34 activated. This is in the backrest part 14 arranged. The second actuator 34 may be a linear actuator, which is designed as a stroke actuator and preferably serves as positive guidance at the same time. This on the seat carrier 18 held second actuator 34 engages with its one end area at the point of articulation 44 the scenery 50 of the backrest part 14 and thus forms regardless of its stroke position in each case the opposite of the ground or the like highest part of the seat support 18 out.

In a left / right movement in x-direction transverse to the direction of travel 62 So can the seat angle of the seat of the seat part 12 with fixed in the seat longitudinal direction articulation point 42 the seat of the seat part 12 on the seat carrier 18 by pivoting the seat part 12 relative to the backrest part 14 be adjusted. It can be with the seat 10 at a relatively short adjustment also achieve a large backrest inclination change. While the backrest part 14 in addition to his forced tour of the scenery 50 is moved in the direction of displacement D, the seat surface of the seat part rotates 12 by changing the seat angle α (α ≠ constant) enclosed between the seat surface and the backrest part surface about its point of articulation determined in the seat longitudinal direction (y direction) 42 in the direction of rotation 52 of the seat part 12 about a rotation axis C on the seat support 18 ,

2 shows the joystick 60 that of a display area 46 is surrounded. The y direction 26 is the second direction of movement 22 and the x direction 24 the first direction of movement 20 assigned. To the directions of movement 20 . 22 clearly the 1 to assign is in both 2 and 1 a coordinate system with the y and x direction shown.

The joystick 60 is preferably arranged horizontally in the motor vehicle. The display area 46 contains the directional arrows that the user uses to control the actuators with the joystick 60 can perform. Between the direction of movement 20 and 22 lie in the display area 46 Fields that allow either a control of two actuators simultaneously or if this is not technically desirable or useful, an actuator is then driven, if essentially a movement in the x direction 24 is performed. Does the movement go in a substantially y-direction 22 via, another actuator is activated. The second variant of the independent control shown here follows the exemplary embodiment already described 1 with its first and second actuator 32 . 34 ,

1 However, also shows examples in which actuators can be controlled simultaneously. The joystick 60 takes over switchable activatable by other actuators, which are described in the following embodiments.

Such another embodiment is the operation of a lordosis adjustment 40 by the adjustment switch arrangement according to the invention, the combination lordosis 76 and joystick 60 ,

1 shows the lordosis adjustment 40 in the backrest part 14 of the seat 10 , For the forward and backward movement of the lordosis is a fourth actuator 66 and for the up and down movement, a third actuator 64 present (not shown) leading to the lordosis adjustment device 40 belongs. These actuators are now after switching through the switch lordosis 76 under operation of the joystick 60 operable. A movement of the joystick 60 in X direction 24 is with the up and down movement of the lordosis with the third actuator 64 coupled and a movement of the joystick 60 in the y direction 26 is with the forward and backward movement of the lordosis thus with the fourth actuator 66 controllable. In this embodiment, it is executable that during a movement of the joystick 60 between the direction of movement 24 . 26 , for example, obliquely forward, both a movement of the Lordosis forward as well as to the right or to the left takes place, accordingly both actuators 64 . 66 be controlled.

Analogous to this is through the joystick 60 the control of the height and length adjustment of the entire seat 10 configurable. 1 does not show in detail the associated actuators. However, that is 1 removable, that the seat carrier 18 a fifth actuator 68 and a sixth actuator 70 can be assigned. The fifth actuator 68 serves the up and down movement of the seat 10 while the sixth actuator 70 the forward and backward movement of the seat 10 takes over. The control is again in accordance with the same direction of movement of the joystick 60 and seat movement, namely the movement of the joystick 60 in the y direction 26 acts on the forward and backward adjustment of the seat 10 through the sixth actuator 70 and the left / right movement of the joystick 60 in X direction 24 on the up and down movement of the seat 10 through the fifth actuator 68 , Both actuating movements are correspondingly superimposable when the joystick 60 a movement between the direction of movement 24 . 26 performs.

The tolerance field within the display area or the associated control in the x direction 24 or in the y direction 26 for the transmission of a drive signal for two actuators is within a corresponding control program for joystick 60 and actuator function can be specified. There is the possibility of not allowing joint control by only exact movements in the x or y direction 24 . 26 be allowed. A superposition of multiple actuators is not possible. On the other hand, a large tolerance field can be specified, so that deviations from the exact direction of motion immediately lead to the control of two drives.

Finally, a preferred embodiment, the control of the known inclination adjustment of the backrest part 14 over the swivel joint 16 , Here is only one direction of movement of the backrest part 14 required back and forth. Thus, by the adjustment switch assembly, the joystick 60 , So only one direction of movement to be executed. After switching over by a switch joint inclination adjustment 80 is according to the invention only a seventh actuator 72 controllable. This seventh actuator is in 1 not visible. It is preferably located in the region of the swivel joint 16 and causes a tilt adjustment of the backrest part 14 around a rotation axis F while changing the seat angle α. The seat part 12 will not be changed. There are thus only direction of movement of the joystick 60 processed, in the same movement in and against the direction of travel 62 Act. This movement corresponds to the y-direction 26 of the joystick 60 , Movements across the direction of travel thus remain without reaction.

Finally, to return to the original tilt adjustment by means of first and second actuator 32 . 34 a switch tilt adjustment 74 who in 1 below the joystick 60 is shown arranged.

Other switch element are in the area of the joystick 60 arranged, on the one hand, a switch to a passenger seat (not shown) allow. This gives the same features from a single joystick 60 transferable and controllable to a passenger seat or a rear seat.

To simplify a desired basic position of the seat is also an in 1 displayed memory button 84 arranged. Pressing this button will successively without manual operation of the joystick 60 the actuators 32 . 34 . 64 . 66 . 68 . 70 . 72 controlled and a previously stored position of the seat 10 set. For this function, several memory buttons for several positions using the motor vehicle are conceivable. It is also possible, for example, if the switch passenger seat 82 is pressed, that the memory function after pressing the memory button 84 on the passenger seat or a back seat acts. The memory function is by pressing another switch 74 to 80 canceled.

The features described here are the joystick 60 are assignable, have exemplary character and may refer to other well-known functions of the seat 10 be transferred equivalent. In addition, regardless of the vehicle seat 10 Functions conceivable in which, for example, the ventilation of the motor vehicle and / or the heating of the motor vehicle interior and / or the seat heating by the movement of the joystick 60 are controllable. The directions of movement are not on the direction of movement 24 . 26 limited, but can be extended three-dimensional.

The respectively controlled adjustment planes 16 . 28 . 30 . 36 . 38 . 40 or their associated switch 74 to 84 are also visually directly on the control of the joystick 60 and / or can be displayed in the immediate vicinity and / or in the display panel of the cockpit.
