Description

The present invention relates to a vehicle seat according to the preamble of claim 1.

  The vehicle seat of an automobile comprises at least one seat cushion and a seat back provided with a seat shape predetermined by the cushion element and each spring system. Objects constructed as this type of vehicle seat conventionally comprise unsprung equipment covered by a cushion pad and then by a corresponding seat cover. In this case, the stitched seam of the stuffing and seat cover will reduce the symptoms of fatigue as much as possible when sitting for a long time for the driver of the car and as best as possible for the specific body structure of the driver. An adapted sheet shape is provided. For this reason, it is known to provide a vehicle seat with one or more pneumatic elements that allow the seat shape to be adapted to the particular driver in an optimal manner via a controller and by means of a pressure generator. The disadvantage of these relatively large pneumatic elements is that the action on the seat shape is limited due to the relatively thick cushion pads of the backrest and seat cushion, respectively.

Furthermore, in the case of vehicle seats, in particular in the case of truck vehicle seats, it is known to provide a pneumatic element in the seat, which is pressurized via a control device and various massages via the pneumatic element. Function can be realized. By such means, a seat shape that changes periodically is created in the same way as a massage pad for a vehicle seat composed of small particles, and the symptoms of fatigue caused by sitting on the vehicle seat for a long time are constant. Can be prevented by this method. The disadvantage here is that the pneumatic elements are generally connected with each other in a pneumatic and thus pressure-related manner, so that they have a small effect and / or are large or under the cushion pad of the vehicle seat. The cover is bound to a fixed position on the cushion pad in the event of a slightly high pressure, and the massage effect is relatively weak, avoiding effective transmission of pressure to the driver's body. Is Rukoto. Patent Document 1 has already disclosed the integration of a plurality of cushion-shaped air cushions that are small with respect to the seat-shaped surface in the vehicle seat, and this air cushion is fixed by a controller for acting on the seat shape. As a result, a different massage effect can be obtained. In this case, the exact arrangement of the seat cushion and the air cushion in the seat back is not described. Similarly, Patent Document 2 discloses a vehicle seat in which a large number of small air cushions are embedded in the cushion and can be operated via separate lines in order to change the seat shape. Finally, Patent Document 3 and Patent Document 4 similarly disclose a vehicle seat in which a small air cushion is arranged in the cushion.

German Patent No. 4331663C1 Specification JP 60154925 A US Pat. No. 4,655,505 US Pat. No. 5,155,585

In contrast, the present invention has the object of providing a vehicle seat of the type described at the outset, in which the pressure elements are arranged in the seat as effectively as possible for the desired seat shape.

  The object of the invention is achieved by a vehicle seat having the features of claim 1. Preferred developments and improvements of the invention are the subject of the dependent claims.

Each vehicle seat includes a seat cushion and a seat back provided with a plurality of pressurizing elements for acting on the seat shape, and a controller for constant pressurization of these elements. Thus, a different massage effect can be obtained. The pressurizing element is a cushion-like element that is small relative to the sheet-shaped surface and can be actuated separately via lines in order to change the sheet shape substantially in the form of dots . Therefore, first, the pressure is generated substantially in the form of dots, so that the sheet shape can be changed in a certain manner, so that an effective massage function can be realized by the pressurizing element. Because the pressure element is a relatively small cushion-like element, the required volume is small and thus the reaction time is short. Since only a small additional space volume is required, the massage function can be adapted to the existing seat. It is quite enough to change the sheet shape constantly and to realize the massage function effectively by simply generating pressure in the form of dots in individual elements or in combination with multiple pressure elements. It is. There is only a small volume of pressure element, but by increasing the pressure in the form of dots in the seat back and seat of the vehicle, the seat shape with the lining and / or stuffing and cover, and this Together with the sheet shape, the sheet shape can be changed in a certain and effective manner. In this case, the pressurizing element is arranged between the filling of the vehicle seat and the cover. Therefore, the effect of generating pressure substantially in the form of dots by the pressurizing element can be further increased. In this case, substantially punctiform means a relatively small area with respect to the entire surface of the seat back of the seat or of the vehicle seat, which can be operated separately by the individual pressurizing elements, in particular 5 to 5 It should be understood that it means an area of about 10 cm 2 . The number and arrangement of specific elements is preferably distributed substantially throughout the sheet-shaped surface, but may be limited to individual, constant areas.

  According to one preferred refinement of the invention, the desired fixed seat shape can be set by the vehicle seat pressure element and the controller. Based on this preset fixed sheet shape, i.e. the sheet shape defined by the different pressurization of the individual pressure elements, the individual pressure element or the plurality of pressurization elements of the entire region, e.g. It is preferred that the massage function can be realized in a simple and effective manner, for example by changing to or by operating in combination, for example, and the seat shape adapted exclusively for the driver is easily restored later. Thus, the preset seat positions for multiple users as well are related in a certain way, i.e. to certain orthopedics and / or comfort, as has already been realized in automobiles from time to time. According to the conditions, the vehicle seat can be adapted to different vehicle users. According to the invention, the sheet shape can always be restored again or automatically restored after one or more massage operations have been performed. This is preferably done by pressing the individual elements, each having only a small volume and thus a short reaction time. The shape adjustment according to the invention with a combined massage function occupies a small space and can be easily adapted between the individual elements of the vehicle seat, in particular the unsprung equipment, the filling and the cover of the seat. .

  According to one preferred refinement of the invention, the pressing element is fixed to a seat-like support insert and is arranged under the lining of the vehicle seat, which lining is covered by a seat cover. This facilitates assembly of the seat according to the present invention. This is because the individual elements and their connecting lines are fixed to the support surface to prevent the vehicle seat from sliding or moving during the production of the vehicle seat. Thus, even a constant massage of individual locations within the sheet-shaped region is possible, since the position of a particular pressure element is established accurately.

According to a further preferred refinement of the invention, the shape of the pressure element is such that a substantially point-like pressure region can be created within the sheet shape. This avoids the movement of the seat cushion or the backrest, or at least the majority of its entire area, by moving one element as well. Pressing in the form of dots has the particular advantage that the sheet shape can be preset in more various forms, as well as the variety of massage functions that can be achieved with the sheet. The shape of the pressurizing element that is substantially adapted to generate the pressure region in a point-like manner is, for example, an oval or circular shape with a boundary seam on the side, so that the element is pressurized Is enlarged only in the transverse direction with respect to the substantially sheet-shaped surface. As an alternative to the shape of the pressure element so that pressure can be generated in the form of dots, a bellows-like side region connected by opposing sheet-like side walls may be provided. Here too, pressure is generated substantially in the direction of the surface of the seat surface and of the backrest, and in this connection the element expands on both sides , so that a sheet-like (non-point-like) pressure is also present. It does not occur. Of course, instead of this, according to this aspect of the present invention, other substantially point-like pressurization, i.e. constant and effective pressurization, and any other setting of the desired sheet shape can be achieved with respect to the massaging operation. It is also possible to use a pressing element having an arbitrary shape.

  According to another preferred refinement of the invention, the pressure elements can each be operated by a separate line, which is arranged on the surface of the support insert, fixed and grouped in the direction of the control element. To be one. With such an arrangement, a simple, sheet-like support insert can be fitted and secured to the layers of the seat, so that during the production of vehicle seats, the installation of the pressure elements and their lines is simplified. Become. In addition, the connecting line of the control device or of the pressure generator is therefore as short as possible, and the corresponding reaction time when pressurized is correspondingly shortened. Furthermore, securing to the surface of the support insert has the advantage that the required spatial volume is reduced to a minimum in the vertical direction.

  According to a further preferred refinement of the invention, the pressurizing element can be pressurized by pneumatic or electropneumatic pressure. As an alternative, pressurization by a fluid may be performed, but it is preferable to use air in consideration of a leakage problem.

  According to a further preferred refinement of the invention, the controller is adapted to perform a plurality of massage functions which are preset and can be set individually. The massage function is realized by combining specific pressure elements within the sheet-shaped region, periodically changing and / or individually actuating. In particular, this makes it possible to carry out known types of massage, such as, for example, a reflex area massage, including a certain massage of individual areas of the body.

  According to another preferred refinement of the invention, a plurality of preselected settings of the sheet shape can be stored by the controller. This allows a certain adaptation of the seat shape, which is important when driving for a long time, to be stored in each case for different vehicle users, in particular in the case of trucks. A particular seat shape can be particularly adapted and preferably stored in this adapted manner in a manner similar to presetting the seat position (seat height, backrest gradient, distance from the pedal, etc.). All that a particular driver has to do is select a preset that is optimized for his physique, which is realized by the controller via the pressurizing element.

  Further advantages, preferred refinements and details of the invention can be found from the following description, which describes and describes the invention in more detail with reference to the exemplary embodiments illustrated in the drawings.

  A first exemplary embodiment of a vehicle seat according to the present invention combining a massage function and shape adjustment is schematically illustrated in the oblique view of FIG. As is known, the vehicle seat 1 includes a seat cushion 2 and a backrest 3 that are connected to each other in an articulated manner. The vehicle seat 1 is provided with a plurality of pressurizing elements or pneumatic elements 4 that can be operated by air pressure by a pressure generating device (not shown) via the connection lines 6 under the cover 8. The pneumatic element 4 preferably has a relatively small volume or surface enlargement, which allows the pressure to be generated substantially in the form of dots. In the exemplary embodiment shown here, the shape of the pneumatic element 4 is substantially oval or circular, and a small pressure pad or pressure cushion is within a selected region of the seat shape of the vehicle seat 1. Formed. As an alternative, the illustrated pneumatic element 4 may be provided throughout the seat shape. The pneumatic elements 4 are fitted and clamped to the sheet-like support insert 9 so that their respective position within the sheet-shaped surface is established accurately. Moreover, this facilitates assembly. The operation of the pneumatic element 4 takes place by itself, in combination or sequentially via a controller 5 arranged in the region of the seat back 3. Each pneumatic element 4 is separately provided with the required air pressure by the controller via a separate connection line 6. Therefore, the realization of a massage function exactly the same as the realization of a constant sheet shape can also be realized in an effective and effective manner with a relatively small volume in the medium or compressed air, i.e. a relatively low pressure.

  FIG. 2 is a side cross-sectional view schematically illustrating a vehicle seat 1 according to the exemplary embodiment of the present invention of FIG. The construction and structure of the vehicle seat can be found here. That is, the construction of the seat cushion 2 and the seat back 3 of the vehicle seat 1 respectively comprises, in particular, an unsprung installation 11, a stuffing 7, a lining 10, and a cover 8 covering these elements. In this exemplary embodiment, an insert according to the invention of a pneumatic element for massage function and seat shape adjustment is arranged between the padding 7 and the lining 10. A relatively small, separate pneumatic element 4 is arranged in the vicinity of the seat-shaped surface of the vehicle seat 1 and allows adjustment of specific areas or points of the seat surface and back surface with low pressure and small volume. . The controller 5 is preferably arranged in the region of the backrest 3 and therefore no additional space volume is required.

  FIG. 3 is a diagram illustrating an exemplary embodiment of a vehicle seat according to the present invention in a view similar to FIG. 2, in which two selected pneumatic elements 4 are illustrated here in a pressurized state. The two pressurized pneumatic elements 4 each create a local bulge at a predetermined point, but substantially the entire shape of the vehicle seat does not change. In other words, after the two elements 4 are pressed, it is certain that the original sheet shape is obtained again. Similarly, the situation illustrated in FIG. 3 is within the lumbar region and the anterior seat surface region for an orthopedic or other type of adaptation that is optimal for a driver's body. The driver may have a pre-selected constant seat shape with respective heights.

  FIG. 4 is a diagram illustrating a variation of the shape of the pneumatic or pressure element 4 according to the invention. A feature common to all of the shapes illustrated in FIG. 4 is that the shape is capable of substantially point-like pressurization by a pneumatic element. Moreover, the element 4 has a relatively small volume and its surface expansion is small relative to the entire sheet-shaped surface. Each pneumatic element 4 is provided with a respective line connection 6 through which pressure is supplied and pressure can be removed again. Variations of the shape illustrated as an example that can generate pressure in the form of dots are the following shapes. That is, an oval shape, an eye shape, a bellows shape with a constricted side, a two-chamber shape, an oval shape with a protruding bulge, and an oval shape with a plurality of ledges formed. Of course, other configurations and variations of the arrangement according to the present invention for massage and adjustment of the seat shape of the vehicle seat are possible as long as it is possible to generate pressure in a substantially point-like manner, requiring less space. The form may be preferred.

  FIG. 5 shows two variants of the design and arrangement of each line connection 6 for an individual pneumatic element 4 (not shown). The illustrated first variant line 6 is a clamped cylindrical line placed on a support insert 9 and is bundled in the direction of a controller or pressure generator (not shown). Is one. Fixing on the support insert 9 has the advantage that it is easier to assemble, and clamping on the surface of the support insert 9 has the advantage that only a small space volume is required in the vertical direction. Have. As an alternative, in the second variant illustrated, a plurality of channel-like lines 6 having a rectangular cross section are provided on the support insert 9 and can be realized, for example, by welding a plurality of thin film layers. .

  All of the features illustrated in the description, the claims and the drawings may fall within the scope of the invention, either as such or in any desired combination.
