DETAILED DESCRIPTION

[0084] FIGS. 1, 4 and 6 show a seat (1), in particular a vehicle seat. The seat (1) comprises the components seat cushion section (12), backrest (13), headrest (14) and at least one armrest (15). The seat is oriented along the seat directions (X1, Y1, Z1). These seat directions are the longitudinal direction (X1), the width direction (Y1) and the height direction (Z1).

[0085] The seat (1), in particular the vehicle seat is equipped with an operating device (2) for setting seat parameters (3), wherein the operating device (2) comprises at least one multifunction operating element (4) comprising at least one selection element (5), by means of which at least two operating levels (6) can be selected, wherein the multifunction operating element (4) can be moved in at least five switching directions (7), preferably six switching directions (7), wherein each switching direction can be assigned to (7) a certain function (8), which is associated with the selected operating level (6) and which changes a seat parameter (3).

[0086] With the selection element (5), a certain operating level (6) is selected, which comprises a group of functions, for example, the adjustment of the seat parameters (3) for the entire seat (1) or a specific component (12, 13, 14, 15) of the seat (1). A corresponding overview is shown in FIG. 13.

[0087] Alternatively, both an operating level (6) can be selected and a specific function (8) can be operated directly by means of the at least one selection element (5).

[0088] The operating device (6) comprises a control unit (16) which receives a control signal (16) from the multifunction operating element (4). Furthermore, a corresponding selection signal or a control signal of the selection element (5) is received, as shown in FIG. 12. The control unit (16) then controls the corresponding devices to change the seat parameters (3) accordingly. Such devices are actuators (17), one or a plurality of spring and/or cushioning device(s) (18) or one or a plurality of seat comfort device(s) (19).

[0089] The at least one multifunction operating element (4) may be arranged on a lateral section (12a) of the seat cushion section (12). This can be seen in FIGS. 1, 4, 5 and 6, for example. Furthermore, the multifunction operating element (4) may be arranged on a lateral section (15a) of the armrest (15). The respective lateral section is located at the lateral boundary of the seat cushion section (12) or the armrest (15) in the width direction (Y1) of the seat (1).

[0090] In this case, the multifunction operating element (4) is designed in a tabular form.

[0091] While in FIG. 1 a seat with only one multifunction operating element (4) is shown, FIGS. 4 and 5 show an embodiment in which the seat (1) has two multifunction operating elements (4). In this case, the first multifunction operating element (4a) is arranged on the seat cushion section (12) and the second multifunction operating element (4b) is arranged on the armrest (15). In the case of two existing multifunction operating elements (4, 4a, 4b), both multifunction operating elements (4, 4a, 4b) may have the same operating levels (6) with the associated functions (8) or different operating levels (6).

[0092] The respective multifunction operating element (4) can be moved in six switching directions (7, 7a-7f), wherein the multifunction operating element (4) has three axes of movement (X, Y, Z).

[0093] This is shown in FIGS. 2a to 2d. Two opposite switching directions (7) are oriented along a movement axis (X, Y, Z), respectively.

[0094] FIG. 2b shows a first (7a) and a second switching direction (7b) of a translational movement of the multifunction operating element (4) along a first axis of movement (X) in opposite directions. The multifunction operating element (4) can thus be moved by pulling or pushing along the first (7a) or second switching direction (7b). The first movement axis (X) extends along the horizontal longitudinal direction (X1) of the seat (1).

[0095] The third (7c) and the fourth switching direction (7d) correspond to a translational movement of the multifunction operating element (4) along a second movement axis (Z) in respectively opposite directions.

[0096] Alternatively, the third (7c) and the fourth switching direction (7d) may correspond to a rotational movement of the multifunction operating element (4) about the first movement axis (X) in opposite directions. The second movement axis (Z) extends along the height direction (Z1) of the seat and is perpendicular to the first movement axis (X). Both a translational movement of the multifunction operating element along the second movement axis (Z) and a rotational movement of the multifunction operating element about the first movement axis (X) means a movement of the multifunction operating element (4) up or down for the person in the seat. The multifunction operating element (4) is connected to the seat cushion section (12, 12a) or the armrest (15, 15a) by means of a joint.

[0097] The fifth (7e) and sixth switching direction (7f) correspond to a rotational movement of the multifunction operating element (4) about the third axis of movement (Y) in opposite directions, respectively. The third movement axis (Y) extends along the width direction (Y1) of the seat (1) and is perpendicular to the first movement axis (X) and the second movement axis (Z).

[0098] The pivot point may be arranged centrally, off-centre of the multifunction operating element (4), as shown in FIG. 3c. Depending on the choice of the pivot point, a certain rotational movement of the multifunction operating element (4) results.

[0099] Alternatively, the pivot point could be located at a front end of the multifunction operating element (4), as shown in FIG. 3a. In FIG. 3b, an embodiment is shown in which the pivot point is arranged at the rear end of the multifunction operating element (4).

[0100] The one selection element (5) is arranged on a surface of the tabular multifunction operating element (4). In FIG. 8, various possible surfaces are shown. In FIG. 8a, the selection element (5) is arranged on the surface, which is bounded by the length (L) and the width (B) of the multifunction operating element (4). In FIG. 8b, the selection element (5) is arranged on the surface, which is bounded by the height (H) and the length (L) of the multifunction operating element (4). In FIG. 8c, the selection element (5) is arranged on the surface, which is bounded by the height (H) and the width (B) of the multifunction operating element (4). The selection element (5) may be a multi-stage switch or button. For example, a multi-stage slide switch is shown in FIGS. 8a to 8c. FIG. 11 shows a cross-shaped rocker switch. Furthermore, the multifunction operating element (4) may be equipped with haptic elements (9) and/or a grip layer (20).

[0101] FIGS. 10 and 11 show an embodiment in which a display device (11) is arranged on the multifunction operating element (4). The selected operating levels and the selected functions can be displayed by means of such a display device.

[0102] Furthermore, the multifunction operating element (4) is provided with identification elements (10) by means of which the switching directions can be identified. Such identification elements (10) can be seen in FIGS. 7, 8, 9.

[0103] In FIG. 7, identification elements in the form of recesses (10a) at the front and rear ends of the multifunction operating element (4) are shown which can serve to identify the first and second switching directions (pull/push). Front and rear end are understood to mean the surfaces bounded by the height (H) and width (B) of the multifunction operating element (4).

[0104] Furthermore, recesses (10b) may be provided on the top and bottom of the multifunction operating element which can serve to identify the third and fourth switching directions (pull up/push down). The top and bottom are the opposing surfaces bounded by the length (L) and width (B) of the multifunction operating element (4).

[0105] In FIG. 7b, there is a recess (10c) for identifying the fifth (7e) and the sixth switching direction (7f) with a shape corresponding to the finger position during the rotational movement in the fifth and the sixth switching direction.

[0106] The respective identification elements (10) may also be illuminated.

[0107] A specific switching direction (7) of a function (8) of a first operating level (6) can be assigned to a change in a seat parameter (3) of a first element (1, 12, 13, 14, 15), which may be the entire seat (1) or a component (12, 13, 14, 15), with respect to a particular seating direction (X1, Y1, Z1). The same switching direction (7) of a function (8) of at least one further operating level (6) can be assigned to a change in a seat parameter (3) of a second element (1, 12, 13, 14, 15), which may be the entire seat (1) or a component (12, 13, 14, 15), with respect to a same seating direction (X1, Y1, Z1).

[0108] Furthermore, a movement of the multifunction operating element (4) in a switching direction (7) with respect to a movement axis (X, Y, Z) can cause a similar change in the position and/or orientation of the entire seat (1) or at least one component (12, 13, 14, 15) with respect to a seat direction (X1, Y1, Z1) parallel to the axes of movement (X, Y, Z).

[0109] FIG. 12 shows an operating device (2) according to one embodiment. The operating device (2) comprises a control unit (16), a touch screen (30) and a transmitting and receiving device (39), which are based on wireless technology, for example Bluetooth, NFC (Near Field Communication) technology, RFID (Radio Frequency identification) or Wireless LAN.

[0110] A user (40) may make an entry on the touch screen (30) by means of user inputs (32, 33). A first user input, which is preferably carried out as a swiping movement on the touch screen (30), represents a selection of a control panel (31), which is assigned to an operating level (6).

[0111] Due to an actuation (45) of the activation element (34) or due to an activation (33) by the multifunction operating element (4), a first activation signal (41) is initially transmitted to the touch screen 3, whereby the touch screen (30) is activated. Thereby, a first control panel (31, 31a) (not shown in FIG. 12) is displayed on the touch screen (30).

[0112] An operation of a particular function (8) can now be performed by a second user input (33) on the touch screen (30), which is typically a tapping movement. Likewise, such a second further user input (33) may be a movement of the multifunction operating element (4) along a switching direction (7).

[0113] On the basis of user inputs (32, 33) of the user (40), a first control signal (42) is transmitted from the touch screen (30) or the multifunction operating element (4) to the control unit 9. The control unit 9 is thereby informed as to which user input 5, 6 it is and how often or to what extent such a user input 5, 6 is made.

[0114] The control unit then sends a corresponding actuation signal (44) to the corresponding actuator (17) and/or the corresponding spring and/or cushioning device (18) and/or the corresponding seat comfort device (19).

[0115] Furthermore, after a selection of a control panel (31), an identification signal (38) can be transmitted from the touch screen (30) to the control unit (16), in particular after a predetermined first duration. After the control unit (16) has received the identification signal (38), the control unit sends a second activation signal (43) to at least one actuator (17) and/or spring and/or cushioning device (18) assigned to the operating level (6) and/or seat comfort device (19) to activate these devices (17, 18, 19) briefly and thus to provide the user with feedback about the currently selected operating level (6) or the seat parameter currently to be set.

[0116] It is also conceivable that only one connection from the control unit (16) to the actuator (17) and/or spring and/or cushioning device (18) and/or seat comfort device (19) is established, and based on the corresponding second user inputs (33), an activation actuation of these devices (17, 18, 19) by the control unit (16) is performed.

[0117] In addition, it is conceivable that upon actuation (45) of the activation element (34), a test signal (46) is transmitted from the activation element (34) to the control unit (16) as to whether the first control signal (42) originates from the touch screen (30).

[0118] Furthermore, the control unit (16) can send a deactivation signal (47) to the touch screen (30) after a predetermined second duration, as a result of which the touch screen can be automatically deactivated.

[0119] Finally, a mobile device (36) may be connected with the operating element (2) by means of a wireless technology, so that a data exchange is enabled. For this purpose, the operating element (2) comprises a corresponding transmitting and receiving device (39).

[0120] FIG. 23 shows a change or switching between different control panels (31) by means of a first user input (32), wherein a first control panel 31a, a second control panel 31b, a third control panel 31c and a fourth control panel 31d can be seen. Of course, fewer control panels 4 or more control panels 4 may be present, wherein at least two control panels 4 are advantageous.

[0121] As can further be seen, the control panels (31, 31a, 31b, 31c, 31d) are displayed by means of a touch screen (30), whereby in this case the activation element (34) is designed as part of the touch screen (30).

[0122] A seat height adjustment is displayed by the first control panel (31a), a vertical seat cushioning by the second control panel (31b), a longitudinal seat adjustment by the third control panel (31c) and a backrest tilt by the fourth control panel (31d). The corresponding operating levels are indicated by corresponding symbols.

[0123] By means of first user inputs (32) it is possible to switch between the control panels (31, 31a, 31b, 31c, 31d). In this case, the first user input (32) is a swiping movement.

[0124] The respective control panels (31, 31a, 31b, 31c, 31d) have at least one control sub-panel (48), which is designed as a sensitive key area. A corresponding input can be made by means of a second user input (33), which may be a tapping movement or else a swiping movement.

[0125] FIG. 24 shows an alternative representation of a control panel (31) in which a plurality of seat parameters belonging to different components can be set in a control panel. In the present case, this is a seat height setting, represented by the up and down arrows, and a seat longitudinal adjustment, represented by the arrows to the left and to the right.

[0126] In FIGS. 14 to 22, corresponding functions with the associated switching directions are shown according to one embodiment. Table 1 gives an overview of this.

[0127] According to FIG. 14a, the first (7a) and second (7b) switching direction (push-pull, shift) of the seat longitudinal adjustment can be seen in the operating level entire seat (1). When pushing, the entire seat (1) moves forward. When pulling, the entire seat (1) moves backwards.

[0128] According to FIG. 14b, in the operating level entire seat (1), the third (7c) and fourth (7d) switching direction (press down/press up; push-pull) are assigned to the seat height setting. When pushing up (pull), the entire seat (1) moves upwards. When pushing down (push), the entire seat (1) moves down.

[0129] According to FIG. 15, in the operating level entire seat (1) or backrest (13), the fifth (7e) and sixth (7f) switching direction (tilt grip (flip)) are assigned to the backrest inclination setting or the entire seat inclination setting. When tilting backwards, the backrest (13)/the entire seat (1) tilts backwards. When tilting forwards, the backrest (13)/the entire seat (1) tilts forward.

[0130] According to FIG. 16a, in the operating level seat cushion section (12) the first (7a) and second (7b) switching direction (push-pull, shift) are assigned to the seat section longitudinal adjustment. When pushing, the seat cushion length becomes longer. When pulling, the seat cushion length becomes shorter.

[0131] According to FIG. 16b, in the operating level seat cushion section (12), the fifth (7e) and sixth (7f) switching direction (tilt grip (flip)) are assigned the seat section tilt setting. When tilting backwards, the seat cushion section (12) tilts backwards. When tilting forwards, the seat cushion section (12) tilts forward.

[0132] According to FIG. 17, in the operating level headrest (14), the third (7c) and fourth (7d) switching direction (press down/press up; push-pull) are assigned to the headrest height setting. When pulling up (pull), the headrest (14) moves upwards. When pushing down (push), the headrest (14) moves down.

[0133] According to FIG. 18a, in the operating level spring and/or cushioning device (18), the third (7c) and fourth (7d) switching direction (press button down/press button up; push-pull) is assigned to the spring and/or cushioning characteristic. When pulling up (pull), the spring and/or cushioning characteristic becomes harder. When pushing down (push), the spring and/or cushioning characteristic becomes softer. The actuation in the third (7c) and fourth (7d) switching direction can take place in several stages, i.e. a further actuation in the same direction makes the spring and/or cushioning characteristic even harder or softer.

[0134] According to FIG. 18b, the operating level spring and/or cushioning device (18) is assigned the first (7a) and second (7b) switching direction (push-pull, shift) of the X-direction. When pushing, the spring and/or cushioning device (18) is turned on. When pulling, the spring and/or cushioning device (18) is turned off.

[0135] According to FIG. 19a, in the operating level seat comfort device (19), lumbar support, the third (7c) and fourth (7d) switching direction (press button down/press button up; push-pull) are assigned to the displacement of the lumbar support peak curvature. When pulling up (pull), the lumbar support peak curvature is shifted upward. When pushing down (push), the lumbar support peak curvature is shifted down.

[0136] According to FIG. 19b, in the operating level seat comfort device (19), lumbar support, the first (7a) and second (7b) switching direction (push-pull, shift) are associated with the setting of the curvature of the lumbar support. When pushing, the curvature of the lumbar support becomes stronger. When pulling, the curvature of the lumbar support becomes slighter.

[0137] According to FIG. 20, in the operating level seat comfort device (19), side bolsters of the backrest, side bolsters of the seat section (12), the third (7c) and fourth (7d) switching direction (press grip down/press grip up, push-pull), are assigned to the setting of the side bolsters of the backrest (13), or the side bolsters of the seat section (12). When pulling up, the side bolsters in the backrest (13) or seat cushion section (12) become narrower.
