Description

Motor vehicle seat system

Technical Field

The utility model relates to a motor vehicle seat system.

Background

For example, motor vehicle seating systems of the type are known. Such systems have a seat adjustment device, by means of which the comfort setting can be changed, for example, by the vehicle occupant. Some such seat adjusting devices are operated pneumatically or hydraulically by means of a fluid, which may be air, for example, but may also be any other gas or a corresponding liquid. For this purpose, fluid is usually filled into or discharged from a fluid-filled bladder of the seat adjusting device in order to achieve a mechanical adjustment of the seat adjusting device. For this reason, pumps capable of increasing or decreasing the pressure of the fluid are often required. Such components are relatively expensive, and it has therefore been proposed in the known motor vehicle seat systems to fill the fluid bladder with an open-cell foam lining. Such foam has spring-elastic properties due to its nature, which tends to expand the bladder. However, if fluid is extracted from the bladder, the bladder remains in an evacuated state and the foam is compressed and thereby establishes a restoring force. If the bladder is refilled with fluid, the restoring force of the foam acts on the inner wall of the bladder and causes it to expand again. In this way, a seat adjustment device can be constructed which opens or closes only fluid lines which can be used to fill or empty the pocket. This is done by the vehicle occupant. This is done in the following way: this process is schematically illustrated in fig. 11A to 11D. A side view of a motor vehicle seat 1 with a backrest 2 and a seat part 3 is shown here. In the example shown, a seat adjustment device 4, which in the example shown is used for lumbar adjustment, for example, is mounted on the backrest 2. An operating device is denoted 8, with which the seat adjusting device can be operated in order to fill or empty the pocket belonging to the seat adjusting device. And 9 denotes a vehicle occupant. If the vehicle occupant 9 wishes to actuate the seat adjustment device in such a way that fluid is added, that is to say the associated bladder is inflated, the vehicle occupant leans forward slightly in the direction of travel (fig. 11B) and then actuates the associated actuating device 8. At this point, the fluid enters the bladder of the seat adjusting device 4 and the compressed foam may expand in the direction of arrow P4. As a result, in this case, the seat adjusting device 4 arches toward the occupant, see fig. 11C. Conversely, the foam in the seat adjusting device can be compressed by the occupant 9 pressing the seat adjusting device 4 in the opposite direction (arrow direction P5 in fig. 11D). When the operating device 8 is operated simultaneously, fluid is pressed out of the pockets of the seat adjusting device 4. If the operating device 8 is no longer operated, the foam in the fluid-filled bladder of the seat adjusting device 4 remains in the current state, since no more fluid can enter or exit the bladder.

Such a device has different advantages, since a seat adjustment device with such a self-inflating bladder can save on the cost of the seat adjustment device, since, for example, no electric components are required, which, by expansion of the foam in the bladder, draws fluid into the bladder. However, such adjusting devices according to the prior art are also disadvantageous. It is important to note here that this adjustment process works relatively slowly, since the occupant must use muscular force to force the fluid out of the bladder. In addition, the foam present in the pocket constitutes a greater flow resistance, so that in the opposite case the expansion of the pocket and thus the suction of fluid into the pocket lasts for a longer time.

SUMMERY OF THE UTILITY MODEL

It is therefore an object of the present invention to further develop a motor vehicle seat system of the type mentioned above such that the disadvantages mentioned do not occur.

This object is achieved by a motor vehicle seat system according to the present invention.

According to the utility model discloses a motor vehicle seat system has the motor vehicle seat, the motor vehicle seat includes at least one seat adjusting device. According to the invention, the seat adjusting device has at least one fluid-filled pocket, in which a spring-elastic device is arranged and which is designed such that the spring elasticity of the spring-elastic device causes the pocket to expand. In the sense of the present invention, the fluid can be any gaseous or liquid substance, preferably air. The motor vehicle seat system comprises at least one fluid line which is connected to a fluid-fillable pouch and by means of which fluid can be filled into the pouch or removed from the pouch. Furthermore, the motor vehicle seat system comprises at least one operating device, the operation of which enables the fluid-fillable bladder to be filled or emptied. In accordance with the invention, one or more flow regions having a reduced flow resistance compared to the material of the spring-elastic device are present in the interior of the bladder. The fluid-fillable bladder is preferably a fluid-fillable, flexible hollow body, the outer envelope of which is fluid-tight, for example air-tight. The housing may be constructed of, for example, TPU film or polyester film.

In this way, it is achieved that the fluid which has entered the pocket can spread more quickly and is not impeded too strongly by the flow resistance of the spring-elastic device. The better the fluid diffuses in the bladder, the faster the response characteristics when filling or emptying the bladder. As a result, the fluid can diffuse more quickly in the bladder or can on the other hand be pressed out of the bladder more quickly by the force of the vehicle occupant.

As the material for the spring-elastic means, in addition to commercially available springs, use is first made of a spring-elastic material which exhibits good restoring properties and can be deformed in any desired manner. Preferably, the material of the spring-elastic means comprises open-cell and/or closed-cell foam. Such foams are available in large quantities and economically and can be cut into any desired shape.

There are in principle a number of possibilities to ensure a reduced flow resistance: for example, it can be provided that the one or more flow regions are configured as channels for the material distribution of the spring-elastic device. These channels in the material reduce the local flow resistance and ensure that the fluid can diffuse particularly well in the capsular bag. Conversely, if the vehicle occupant acts on the bladder from the outside, the fluid flow can also be well pressed out of the bladder through the channel. Alternatively or additionally, it can be provided that the one or more flow regions are present as individual shaped pieces with channels, which are preferably made of felt. The shaped part can preferably be produced by a thermoforming process in which a starting material, for example a felt material, is converted into a suitable shape. The shaped part is inserted into the bag and is inserted in the region of the inlet opening. Starting from there, the inflowing fluid from the fluid line can be distributed in the form by the bladder and the channel. Finally, the one or more flow areas may be formed by a spacer fabric.

According to a further embodiment of the invention, the material of the spring-elastic means can consist of a 3D structure, which 3D structure comprises thermoplastic elastomer fibers, in particular elastomer threads consisting of the elastomer fibers. Such elastomeric fibers are preferably polyester-based elastomeric fibers.

The elastomeric fibers or elastomeric threads may be configured to have different cross-sections and/or configured as fibers that are hollow or solid inside. The shape of the elastomeric fiber or elastomeric thread may be, for example, circular, elliptical, rectangular, or square in outer cross-section. It is also conceivable that for hollow fibers or wires, the internal cross section of the cavity may be circular, oval, rectangular or square, for example. All possible combinations of outer and inner cross-sections are also conceivable here, for example oval outer and circular inner.

The 3D structure formed by the elastomeric threads or fibers may be constructed by the elastomeric threads being randomly arranged or arranged in a predetermined pattern.

To further improve filling and emptying in general, the bladder may have a plurality of fluid inlets. In this way, the fluid flow guided through the fluid line may branch off in front of the bladder, thereby accelerating the filling process. The same applies correspondingly to the emptying process.

The filling of the fluid line and thus also of the bladder is finally effected by the operation performed by the motor vehicle occupant. For this purpose, various devices can be used which ensure that only the fluid quantity is removed from the sack or filled into the sack. For the control, it is therefore preferably provided that the fluid line comprises a valve which can be opened or closed by the operating device. That is, the occupant of the vehicle opens and closes the valve by operating the operating device. This is preferably done in such a way that the sachet can be emptied or filled as soon as the operating device is operated. Different arrangements can be used for this purpose.

According to an advantageous variant, the valve and the operating device can be connected to each other by a bowden cable, the reciprocating movement of which opens or closes the valve. The bowden cable is preferably connected to the operating lever on the operating device side and to the piston on the valve side. The piston advantageously has a seal on the cover piston, which seal is pressed against the valve seat, for example by a compression spring or the like, when the bowden cable is not operated. If the actuating lever is actuated at this point, the piston and thus also the seal are lifted off the valve seat and fluid can flow into or out of the bladder, depending on what adjustment the vehicle occupant wishes to make.

According to an alternative embodiment, it can be provided that the operating device can be coupled to the valve via an operating line which conducts a fluid. That is, in this embodiment, no purely mechanical operation is selected, but rather a pneumatic or hydraulic operation is selected in order to open or close the valve. In this embodiment, the operating device comprises a compressible fluid-filled structure, which is connected to the operating line and is configured, for example, as a bellows. The valve includes a diaphragm that is deformed by operating the operating device and thereby opens or closes the valve. The deformation of the diaphragm is achieved by the movement of a fluid column in a compressible structure which, when compressed, pushes the fluid column towards the diaphragm through an operating line and opens the valve. To close the valve, the pressure on the compressible structure is reduced, the fluid column is correspondingly retracted, and the diaphragm returns to its rest position. The diaphragm itself is connected to a piston of the valve, which is moved by the deformation of the diaphragm in the direction of the valve seat or away from the valve seat. Here too, a seal is preferably provided, which seals the piston against the valve seat.

In another embodiment, it can be provided that the valve is a component of the operating device. In this way, the valve can be opened directly mechanically, for example by an occupant of the motor vehicle operating a switch, so that fluid can flow through the valve.

In general, the motor vehicle seat system according to the invention is suitable for a range of applications. For example, it can be provided that one or more of the seat adjusting devices described above are arranged in the backrest or in the seat part of the motor vehicle seat. Alternatively or additionally, the seat adjusting device according to the invention can also be a component of a side bolster adjustment and/or a seat depth adjustment and/or a lumbar adjustment of a motor vehicle seat. Two or more seat adjusting devices of the above-mentioned type can also be combined with one another. In this way, for example, a 4-way lumbar adjustment can be achieved.

The beneficial effects of the utility model are that, the fluid can spread or can be pressed out from the bag faster through motor vehicle passenger's effort in the bag faster.

Detailed Description

The motor vehicle seat illustrated by way of example in fig. 1 is a component of a motor vehicle seat system according to the invention. The seat adjusting device 4 according to the invention can be arranged in the seat part 3 and/or in the backrest 2. By way of example, but not limitation, in fig. 1a seat adjustment device 4 is provided in the backrest 2, which in the example shown may be a lumbar adjustment device. It is also conceivable to provide a plurality of seat adjusting devices 4 in the backrest 2 and/or in the seat part 3. With the seat adjusting device 4 according to the invention, all possible adjustments that can be envisaged to be achieved by the fluid-fillable bladder can be achieved. It is also possible to combine two or more seat adjusting devices 4 with each other. In this way, for example, a 4-way lumbar adjustment device can be realized. Z denotes a digitalized direction, i.e. substantially the direction in which the backrest 2 extends upwards from the floor. X denotes a traveling direction, i.e., a line of sight direction of an occupant seated in the vehicle seat 1, and Y denotes a lateral direction perpendicular to the X direction and the Z direction.

The seat adjusting apparatus 4 according to the present invention will be described in detail below. Fig. 2 and 3 show a first embodiment of the seat adjusting device 4, which in this and all other embodiments has a fluid-filled bladder 40, which is an air-tight or fluid-tight, flexible housing in which a spring-elastic device 41 is accommodated. In the example shown, the spring-elastic means 41 are made of a compressible material, such as, for example, an open-cell or closed-cell foam, which fills the pocket 40. The bladder 40 (not shown here) is connected to a fluid line, via which the bladder can be filled or emptied with a fluid, preferably air. During filling, the spring-elastic means and thus also the bladder 40 expand into the state shown in fig. 2 and 3. Upon evacuation, fluid is extracted from the bladder 40, the spring elastic means 41 and the bladder 40 are compressed.

According to the invention, the flow resistance of the spring-elastic material is reduced by suitable measures. For this purpose, in this embodiment, openings are provided in the spring-elastic means 41 in the form of a first channel 42 extending substantially parallel to one another and a second channel 43 extending substantially parallel to one another. These openings preferably extend in the transverse direction or in the direction of travel. Other orientations are also contemplated. These openings serve to better distribute the fluid in the bladder 40 and to distribute the fluid flowing into the bladder 40 more quickly, so that the spring-elastic means can expand significantly faster than if no openings were present. The elasticity of the spring-elastic means 41 ensures that when the fluid line is open, said spring-elastic means can expand when the fluid enters the bladder 40. This process is accelerated in that the openings facilitate a supplementary flow of fluid due to the reduced flow resistance. During emptying, pressure is also applied to the bladder 40 during emptying, as a result of which the spring-elastic means 41 are compressed under the effect of the pretensioning force and air can escape from the bladder 40 via the open fluid line, which is facilitated in comparison with embodiments without an opening due to the reduction in volume achieved by the opening and thus due to the reduced compression stiffness of the spring-elastic means 41. As a result of this, emptying can also be carried out more rapidly.

As shown in fig. 4, filling or emptying of the bladder 40 may additionally be improved by providing the bladder 40 with a plurality of fluid inlets. This is shown here by way of example by two fluid channels 5a and 5 b.

In fig. 5, a sectional view similar to that of fig. 3 is shown, wherein it can be seen that, in addition to the openings which are formed here as channels 42, 43, spacer fabrics 44 can alternatively or additionally also be used to improve the diffusion of air. Such a spacer fabric 44 is preferably provided in the region of the air inlet into the bladder 40, so that it can act as a distributor for distributing the fluid in the bladder 40 to the different channels 42, 43.

An alternative or additional embodiment shown in fig. 6 and 7 provides that the dispenser is realized by a shaped part, for example a thermoformed material, such as felt or the like. The distributor 45 has a plurality of openings 46. Here it can also be seen that the distributor 45 is connected to the fluid line 5. The dispenser 45 may be provided on the inlet side of the sachet 40. In the example shown in fig. 7, a spacer fabric 44 as described above is also provided behind the distributor 45. Of course, this embodiment can also be supplemented by the above-described openings or passages 42, 43.

Further embodiments of the motor vehicle seat system according to the invention, which relate to the filling or emptying of fluid lines, are also described below with reference to fig. 8 to 10. Thus, although one fluid line 5 is shown here by way of example, this fluid line is split into two branches 5a and 5b and the bladder thus has two fluid inlets, this is not to be understood as limiting. There may be more than two branches 5a or 5b or there may be a plurality of separate fluid lines 5 or only a single fluid line 5.

In fig. 8, a valve 6 is provided on the fluid line 5, which valve is connected via a bowden cable 7 to an operating device 8, which operating device 8 is configured in the example shown as a handle. The functional principle is explained in detail with reference to a sectional view of the valve 6. The valve 6 is shown in a closed state in fig. 8A. One can see the bowden cable 7 and the bowden cable pull 71 located therein, to which a pulling force can be applied by the operating device 8 operated as described above. The bowden cable pull wire 71 is coupled to the piston 62 such that pulling of the cable 71 moves the piston 62. A seal 61, which in the example shown is a sealing ring, is provided on the piston. The seal 61 is supported on a projection 67, on which the compression spring 64 is also supported on the side facing away from the sealing ring 61 relative to the housing 65 of the valve 60. The outlet 63 of the valve 6 opens into the fluid line 5. In fig. 8A, the valve is closed and the seal 61 is pressed against the seal seat 66 by the pressure spring 64 which applies pressure to the piston 62. If the bowden cable 7 is subjected to a pulling force in the direction P1 on its bowden cable pull wire 71, see fig. 8B, the piston 62 and thus also the seal 61 is pulled away from the seal seat 66 in the direction P1 against the force of the pressure spring 64. Fluid entering the valve 6 from the outside can now flow around the seal 61 into the outlet 63 and thus into the fluid line 5. In this state, when the bladder 40 is emptied, fluid flows from the bladder, through the fluid line 5 into the valve 6 and from there through the valve outlet to the outside. If the force acting on the bowden cable pull 71 of the bowden cable 7 is reduced, the force of the pressure spring 64 ensures that the seal is pushed back into the sealing seat 66. At this point, fluid exchange with the fluid line 5 is prevented.

In an alternative embodiment shown in fig. 9, a valve 6 is also provided on the fluid line 5. But the operation of the valve 6 is effected in a different manner and form than in the previous example. In the example shown, the operating device 8 is a pneumatically or hydraulically operated switch which is in operative connection with the valve 6 via an operating line 10 which leads a fluid (which may be a fluid different from the fluid in the fluid line 5). A detailed functional principle is explained with reference to fig. 9A to 9D.

In fig. 9A, the switch 8 is provided with a button 81. The button 81 cooperates with a compressible fluid-filled structure 82, which may be a bellows, for example. The structure 82 has an outlet to the process line 10. Fig. 9A shows an unoperated state, and fig. 9C shows a state where a pressure P2 is applied to the button 81. Thereby, the structure 82 is compressed and the fluid located therein is compressed together with the structure, when the fluid is at least partly pressed into the operating line 10.

The valve 6 is shown in fig. 9B and 9D. Fig. 9B shows a state of not operating, i.e., corresponding to the operating state of fig. 9A, and fig. 9D shows a state of having operated, i.e., corresponding to the state of fig. 9C.

The valve 6 has a fluid inlet connected to an operating device 8. In the valve 6, a piston 62 is again provided, which is pressed by a seal 61 against a sealing seat 66 of the valve 6. In the inoperative state, the pressure spring 64 ensures that the valve 6 is closed and that fluid cannot flow from the outlet 63 into the fluid line 5 or from the fluid line 5 through the valve 6. For the remaining reference numerals, reference is made to the above description accordingly. A diaphragm 68 is provided between the piston 62 and the fluid inlet of the valve 6, which is arranged towards the operating line 10. If, by operating the operating device 8, fluid is pressed from the structural body 82 of the switch 8 into the operating line 10 and thus towards the fluid inlet of the valve 6 (P2), the diaphragm 68 is deformed, whereby the piston 62 is moved in the direction of the outlet 63. Thereby, the seal 61 is moved away from the seal seat 66 and the valve 6 is opened. Thereby, fluid flows from outlet 63 of valve 6 into fluid line 5 in direction P3. In the emptying mode, in this case, when the valve 6 is open, fluid flows from the fluid line 5 into the valve 6 counter to the direction of the arrow P3 and from there through the valve outlet.

The above-mentioned valve 6 remains open as long as the respective operating device 8 is operated.

Of course, as shown in fig. 10, the operating device 8 itself can also have a valve, which is opened or closed by a suitable switch at this time.

The operation of the seat adjusting apparatus 4 has been described in the foregoing evaluation of the prior art with reference to fig. 11A to 11D. To avoid repetition, please refer to these descriptions.

With the present invention a particularly effective motor vehicle seat system with a seat adjustment device 4 is provided, which can respond more quickly to a change in the seat setting caused by the user, without additional costs arising for this in the realization.

Fig. 12 shows a further embodiment of a fluid-fillable bladder 40 according to the invention. In this embodiment, the spring-elastic means 41 are formed by a 3D structure of elastomer threads 47, which are formed from elastomer fibers and are thermoplastic. This 3D structure can be formed here from elastomer threads 47 randomly or in a predefined pattern. Due to the elastic properties of the elastomer threads forming the three-dimensional structure, the elastic material of the spring inside the bladder 40 ensures that the bladder is under pretension. The intermediate space in the described construction, which constitutes the spring-elastic means 41, allows air or another fluid medium to pass through. The remaining modes of operation correspond to the modes of operation described in connection with the preceding embodiments.
