Description

The invention relates to a device for adjusting side cheeks of a seat part and / or a backrest of a vehicle seat according to the preamble of claim 1.

Anatomically shaped vehicle seats have elevations on both sides of a central seat or backrest pad surface, which provide a lateral support to a passenger, in particular when cornering, as side bolsters. By the pad geometry unchangeably given side cheeks are optimized for the average physique of passengers, but deviates from the physique of a large number of passengers, so that at a fixed predetermined cross-sectional profile of the seat or the backrest narrow passengers feel too low lateral support, while passengers with wide Do not fit the body in the predetermined area between the side cheek contours, so that they sit partially in the seating area on the side cheeks or lean against the side cheeks in the backrest area, resulting in an uncomfortable sitting position with pressure points in the side cheeks.

In order to avoid such inconvenient seating positions, vehicle seats with adjustable side cheeks for the seat part and / or the backrest are known, which are adjustable by means of a side cheek adjustment from a wide, lying to the seat outside position in a narrow, lying towards the center of the seat position ,

From the DE 196 05 779 C2 is a vehicle seat with adjustable seat and backrest cheeks known in which by means of mechanical adjusting the side cheeks are moved in response to a determined by pressure sensors system pressure of a passenger. For this purpose, the seat and backrest cheeks are held as cheek cushion parts pivotable about axes extending in the seat longitudinal direction, so that the seat and backrest cheeks can be pivoted by means of electric actuators from a wide initial position to the center in a narrow setting position. As an alternative to the pivotable adjustment of the seat and backrest cheeks, the seat and backrest cheeks can be displaceably arranged towards the center of the seat. In addition, a combination of pivoting and displacement devices such as a movement of the seat and backrest cheeks on slide guides is provided.

The adjusting device consists in this known vehicle seat of an electric motor coupled via a spindle drive, the two seat cheeks coupled to the center of the seat until a predetermined system pressure on the seat occupant is determined via the pressure sensor. When the vehicle seat is released by a control via a seat occupancy switch is again a return to the wide starting position.

Since both in a pivoting or linear displacement of the side cheeks towards the center of the seat as well as a combination of pivoting and moving the contour or cross-sectional profile of the side cheeks remains unchanged and also in the retracted end position relative to the middle seat or backrest cushion has a significant curvature, the entry and exit of a passenger is made difficult by the side cheeks.

From the DE 197 37 271 C1 is a seat width adjustment for a motor vehicle seat with oppositely pivoted on the seat part and / or on the backrest hinged side support wings known which are rotatable by means of rotatable, in contact with the support wings befindlicher cam surfaces of actuators. The actuators in turn are pivotable by means of an adjusting gear moving cables.

From the DE 90 14 111 U1 is a seat width adjustment known in which only the geometry of a side cheek is pneumatically adjusted by means of an inflatable bellows. However, as the internal pressure of the inflatable bellows decreases, the geometry once set is lost over time.

From the DE 20 2005 006 988 U1 It is known to influence the shape of the side cheek of a vehicle seat by changing the deflection of a spring element which acts on a hinged side wing. A free end of the spring element is displaceable for this purpose by means of an adjusting element.

From the DE 197 50 116 C2 It is known to provide a pivotable against spring force to influence the shape of a side cheek of a vehicle seat. The deflection of the bracket by means of a pull tab acting on the strap, which is to be operated via a pull rope. The brackets are made of spring steel and can be twisted at their attachment points.

From the WO 2006/024268 is a combined adjustment of the side cheeks of a seat part and / or a backrest of a motor vehicle seat known in which the cross-sectional profile of the side cheeks by changing the length and orientation of the side cheeks with respect to the central seat surface and / or backrest surface is adjustable by means of a side cheek adjustment with a combined linear and rotary guide to produce a controlled path movement, the side cheeks, starting from a first end position in which the side cheeks are in a fully retracted state, initially predominantly extended and then pivoted predominantly about a seat or reclining fulcrum until they are in one of the first end position opposite end position in a fully extended state.

It is an object of the present invention to provide a device of the kind set forth which achieves greater comfort with a simple, inexpensive construction, such as e.g. with regard to an ergonomically optimal adaptation to different anatomies of passengers in the seat part and / or in the backrest, the possibility of facilitating the occupancy and departure of a vehicle seat as well as a posterior looking for a passenger, and / or an automatable Adaptation of the seat depending on the current driving situation (eg when cornering) to improve.

The translations and rotations of the side cheeks in or around different axes of the coordinate system combine the advantages of an adjustment of the side cheeks of the seat part in the individual translation and rotational directions, wherein

• In the case of a translation in the X direction, the position of the side cheeks of the seat part can be better adjusted to individual body shapes, for example by displacing the side cheeks in the direction of travel for better leg support in passengers with long legs,
• In the case of a translation in the Y direction, the position of the side cheeks of the seat part is tailored to seat widths of different body shapes,
• A translation of the side cheeks of the seat part in the Z-direction allows easier entry and exit, since the passenger does not have to move over an elevated and thus disturbing side cheek,
• - With a rotation of the side cheeks of the seat part about the X-axis an individual adjustment of the seat width and at the same time adaptation to different seat shapes takes place,
• - A rotation of the side cheeks of the seat part about the Y-axis allows folding away a side wall for easy entry and exit of the passenger and
• - Rotation of the side cheeks of the seat part about the Z-axis ensures improved adaptation of the side cheeks to different leg positions or upper body shapes.

Analogous advantages of a combination of the individual translations and rotations arise in the combined adjustability of the side cheeks of the backrest, for example, a rotation of the side cheeks of the backrest about the Y axis of rotation allows use of the side cheeks of the backrest as an armrest.

The axes of rotation and translational directions X, Y and Z do not necessarily refer to the axes of a vehicle coordinate system, but may also be in a direction similar to the X, Y and Z axes, but with the same operational advantage. In particular, with respect to the side cheeks of the backrest, the directions of movement are slightly different in particular from the X and Z axes of the vehicle coordinate system due to the backrest which is usually inclined in the use position.

Preferably, such combinations of translational and / or rotational adjustment of the side cheeks of the seat part and the backrest are predetermined, which ensure optimum comfort for a passenger both when sitting and when getting in and out and in a rest position.

Preferred combinations of translational and / or rotational adjustment of the side cheeks of the seat part and the backrest are:

• - In a first variant, an adjustment of the side cheeks of the seat part in a first Verstellbene rotationally about the X-axis and in a second Verstellbene translationally along the Y-axis and the side cheeks of the backrest in a first Verstellbene rotationally about the Z-axis and in a second Verstellbene translational along the Y-axis, the translation along the Y-axis allows a side cheek adjustment with large adjustment paths for different body widths and the rotation about the X-axis sideways adjustment with adaptation of the side cheeks to a variety of body shapes,
• - In a second variant, an adjustment of the side cheeks of the seat portion in a first Verstellbene rotationally about the X-axis or translationally along the Y-axis and in a second Verstellbene rotationally about the Z-axis and the side cheeks of the backrest rotationally about the Z-axis or translationally along the Y-axis in a first adjustment plane and rotationally about the X-axis in a second adjustment plane, which in addition to the advantages of the first variant allows adaptation to different leg shapes and settings or upper body shapes,
• - In a third variant, an adjustment of the side cheeks of the seat part in a first adjustment rotationally about the X-axis or translationally along the Y-axis and in a second adjustment plane rotationally about the Y-axis and the side cheeks of the backrest in a first Verstellbene order the Z-axis or translationally along the Y-axis and in a second adjustment plane rotational about the Y-axis, which in addition to the advantages of the first variant allows folding away a side cheek of the seat part or the backrest for easier entry or exit,
• - In a fourth variant, an adjustment of the side cheeks of the seat part in a first adjustment rotationally about the X-axis or translationally along the Y-axis and in a second adjustment plane translationally along the Z-axis and the side cheeks of the backrest in a first adjustment rotationally the Z-axis or translationally along the Y-axis and in a second adjustment plane translationally along the X-axis, whereby in addition to the advantages of the first variant, a side cheek of the seat part by translation in the Z-axis direction and a side cheek of the backrest by translation ensured in the direction of the X-axis driving away the side cheeks for easier entry and exit and
• - In a fifth variant, an adjustment of the side cheeks of the seat portion in a first adjustment rotationally about the X-axis or translationally along the Y-axis and in a second adjustment translationally along the Z-axis and the side cheeks of the backrest in a first adjustment rotationally the Z-axis or translationally along the Y-axis and in a second adjustment plane translationally along the Z-axis, which in addition to the advantages of the first variant by the translation of the side cheeks of the seat part in the direction of the X-axis and the translation of the side cheeks Backrest in the direction of the Z-axis allows individual adjustment of the positions for optimum lateral support of a passenger.

In the combination of a translational and / or rotational adjustment of the side cheeks of the seat part and the backrest according to the fourth variant, the translational Adjustment of the seat part along the Z-axis, preferably by a passively sprung part of the side cheek of the seat part, while for the active translational adjustment of the seat part along the Y-axis, an adjustment drive is provided. As a result, the passively sprung Z-adjustment of the side cheeks of the seat part can be made by the passenger to facilitate entry and exit in the vehicle or the seat itself, while the actively controlled adjustment of the side cheeks of the seat part in the Y direction optimal adjustment of Seat width ensures the greatest possible lateral support of the passenger, especially when cornering.

In general, both side cheeks of the seat part or the backrest are adjusted together and the same, so that always a symmetrical sitting position is maintained. In exceptional cases (such as when the door is open or for an adjustment when cornering), it is also possible that only one of the side bolsters is adjusted. The arranged on both sides of the seat part or the backrest side cheeks can be adjusted synchronously or separately, with a synchronous adjustment of the side cheeks allows the use of a simple adjustment, while a separate adjustment of the side cheeks more personalized settings and additional benefits such as folding away a side cheek to facilitate Entry and exit, providing a one-sided armrest and the like offers. A "simple" design of an adjustment relates in particular to the possibility of having to provide only one drive motor in the case of several (at least two) force-actuated side cheeks.

In a combined adjustment of the side cheeks in several levels, especially in a translational and rotational adjustment in more than two levels and a combined adjustment of the side cheeks of the seat part and the backrest, a program-controlled adjustment of the side cheeks is very easy to use and prevents the convenience impairing incorrect settings.

Both during program-controlled adjustment and during manual adjustment of the side cheeks, it is advantageous to adjust the side cheeks of the seat part and / or the backrest with the inclusion of a sensor signal, in particular a sensor signal emitted by a pressure sensor arranged in the side cheek. An electronic control device, e.g. with a control unit, by means of which the program-controlled or -reggelte adjustment takes place, this does not necessarily have to be part of the at least one side cheek having device and also not necessarily be arranged on or in the vehicle seat. In a variant, the control device may e.g. be formed as a separate component and be coupled to the device, in particular a drive of the device.

For adjusting the side cheeks, the adjusting elements of the two side cheeks can be actuated synchronously or separate adjusting drives for translational adjustment of the side cheeks and the side cheeks can be provided independently of each other for adjusting the lateral cheeks.

While the structural elements of the side walls synchronously actuated adjusting drive for translational adjustment a simultaneous process thus ensuring a uniform adjustment of the side walls allow separate adjustment for rotational adjustment of the side cheeks independent process and thus adjusting the angular position of the side cheeks.

In a preferred embodiment, the adjusting drive for the translational adjustment of the side cheeks consists of a linear drive, in particular a spindle drive and the adjusting drive for rotary adjustment of the side cheeks from a rotary drive (combined with a spindle drive), which has a drive motor and a driven by the drive motor spindle whose thread meshing with a spindle nut connected to the structural elements, wherein with synchronous adjustment of both structural elements of the side cheeks by means of a drive motor, the spindle has opposite, with the spindle nut one of the two structural elements meshing thread pitches.

In this embodiment, a multiway sidewall can be operated with only a total of two drive motors.

In a variant of this embodiment, the structural elements have a first linkage, which via a first joint with a first linear or spindle drive and offset from the first articulation on a second articulation, which are connected via a second joint with a second linear or spindle drive, such in that, in the case of synchronous actuation of the first and second linear or spindle drive, the side cheeks are translationally adjustable and, in the case of asynchronous actuation of the first and second linear or spindle drives, the side cheeks are rotatably adjustable.

Even with this variant, a multi-way side wall can be realized with only a total of two drive motors.

Alternatively, the structural elements may have a first linkage, which via a first joint each having a first linear or spindle drive and offset from the first linkage, a second linkage, which are connected via a second joint, each with a second linear or spindle drive, such that with synchronous actuation of the respective first and second linear or spindle drive, the respective side wall translationally and in asynchronous actuation of the respective first and second linear or spindle drive, the respective side cheek is rotatably adjustable.

In this embodiment, using four adjusting drives separate translational and rotational adjustments of the side cheeks are possible, so that, for example, only one of the vehicle door adjacent side cheek of a seat part can be lowered to facilitate entry and exit.

A reduction in the number of adjusting drives over the two aforementioned embodiments can be achieved in that the structural elements of the side cheeks connected to a linear or spindle drive and by means of acting on the structural elements actuator non-positively and / or positively locked so that upon actuation of the Linear or spindle drive and deactivated actuator, the structural elements are translationally adjustable and with activated actuator rotationally adjustable.

This embodiment allows both a first variant with two separate adjusting drives for the two side cheeks and a second variant with a common spindle drive with a counter-rotating thread pitch and a spindle synchronously blocking the structural elements for rotational adjustment of the side walls and synchronously releasing the translational adjustment of the side cheek actuator ,

The actuators may have a form-locking element which engages to block the respective structural element in parallel to the translational adjustment of the side cheeks aligned Gegenformschlusselemente the structural elements, wherein a Gegenformschlusselementen the structural elements opposite region of the structural elements spring-loaded with the seat part or the backrest is connected.

As an alternative to a linear or spindle drive, the adjustment drive for translational adjustment of the side cheeks can consist of a cable drive, which is connected to a spring-loaded structural element.

The structural elements of the side cheeks of the seat part and / or the backrest can be used in the upholstery of separate, arranged laterally of the seat or backrest side cheeks or for a more compact appearance and to use only a seat or backrest cover for the entire seat and backrest surface in the pages the pad of the seat part or the backrest are integrated.
