Description

Technical Field

[0001] The utility model relates to a module carrier component. Background Art

[0002] Such a module carrier assembly, known, for example, from EP 3 845 415 A1, is usually mounted on a vehicle seat structure and is designed for mounting specific functional components, such as fluid actuators, valve blocks or pumps, thereon. In addition, the module carrier assembly is also used to fix corresponding lines for supplying air to the various components. Such a module carrier assembly is usually located behind the seat cushion of the backrest or the seat part in a vehicle seat.

[0003] In known systems, functional components usually have to be mounted individually on a module carrier. For this purpose, it is necessary to fix pipelines, valve blocks, pumps, etc. The number of parts required for complete assembly and therefore the number of components required is relatively high in this method. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to provide a module carrier assembly, in which the number of components required is reduced compared with the prior art.

[0005] The above technical problem is solved by the module carrier assembly and the vehicle seat proposed in the present application. Advantageous embodiments are disclosed in the dependent claims.

[0006] The utility model reduces the number of required components by integrating at least one part of a housing for accommodating a valve block in a module carrier, thereby eliminating the need for complex installation of fluid pipes and reducing the number of components.

[0007] The module carrier assembly for mounting on a seat structure of a motor vehicle seat and for fixing pneumatic or non-pneumatic components according to the utility model has a module carrier, which has a front side and a back side opposite to the front side. Optionally, the module carrier assembly has at least one further component. In addition, the module carrier assembly includes a housing for accommodating a valve block, wherein, according to the utility model, at least a part of the housing is integrated in the module carrier.

[0008] Here, it can be provided that at least one part integrated in the module carrier is molded on the module carrier or in the module carrier. In this way, in particular when plastic is used as the raw material of the module carrier and the housing, a highly integrated module carrier assembly can be achieved.

[0009] Preferably, the housing can be designed as a multi-part structure, wherein at least two parts are connected to one another, preferably by means of a hinge, an elastic connection or a film hinge. Then, for example, an external component for completing the housing can be connected to the part of the housing that is already integrated in the module carrier by means of a tool-free connection. If at least one part of the housing is a part that is separate from the module carrier, the part that is separate from the module carrier can preferably be mounted on the module carrier by means of laser welding, high-frequency welding, vibration welding, adhesive bonding or clamping.

[0010] The material of the module carrier and / or the housing can be formed in different ways. According to a preferred embodiment, it can be provided in particular that the material comprises or consists of a plastic material, a film material or a felt material. In this case, the carrier material or the module carrier component or the housing can be a part formed by injection molding or by thermoforming or vacuum casting, or include a part formed by injection molding or by thermoforming or vacuum casting.

[0011] Other parts can also be integrated into the module carrier assembly according to the utility model. For example, preferably, it can be arranged that the module carrier includes an integrated fastening section for mounting or placing pneumatic components and / or non-pneumatic components. Pneumatic components can be selected from the following group, for example: pumps, valve blocks, fluid actuators, fluid channels. Non-pneumatic components can be selected from the following group, for example, the group includes the following components: vibration system components, ventilation system components, electrical components, cable harnesses, connectors, covers. Optional additional components can be pneumatic components or non-pneumatic components.

[0012] Sections for fastening hoses or fluid actuators can also be provided on the module carrier.

[0013] According to a preferred embodiment of the module carrier assembly according to the utility model, the module carrier assembly includes a connecting section or a separate connecting section integrated in a module carrier or a part of a housing. Here, these connecting sections are used to mechanically and / or pneumatically connect the housing part and / or the valve block to another component and / or the module carrier itself installed on the module carrier. Therefore, on the one hand, the fluid channel can be connected to the valve block, and on the other hand, a part of the housing for the valve block can be fixed to another part of the housing or the module carrier. Therefore, the parts of the housing and the connecting section can have or provide a flow-guiding connection. Therefore, it is preferably set that the integrated or separate connecting section has a ventilation duct or a ventilation duct section, or is designed to connect the ventilation duct in a fluid-tight manner. If the connecting section itself already contains part of the pneumatic system, whether as a fluid channel or only as a fluid-tight connection between fluid channels, the number of components required for connecting pneumatic components can be reduced, and the entire module carrier assembly can be simplified in assembly technology. The connecting section can have a fluid channel or multiple fluid channels. In the simplest case, the connecting section is designed to be used for plug-in connection. These connecting sections can be formed as plastic parts and can therefore be produced cost-effectively.

[0014] All possible pneumatic components are conceivable, preferably pneumatic components selected from the following group: pumps, valve blocks, fluid actuators, fluid channels. The fluid actuators are in particular pneumatic bladders mounted on the module carrier.

[0015] According to another embodiment of the utility model, it can be provided that at least one part of the housing is a part separated from the module carrier, and the part separated from the module carrier is preferably mounted on the module carrier by laser welding, high-frequency welding, vibration welding, bonding or clamping. In particular, the latter allows tool-free connection, thus ultimately achieving particularly simple assembly.

[0016] The separated part of the shell can also be the part of another vehicle component, so as to further improve the integration level when manufacturing the vehicle seat.Therefore, the separated part of the shell can for example be integrated in another seat element of the vehicle seat, preferably integrated on the back part.

[0017] According to a preferred embodiment, the valve block comprises a circuit board on which the valves and the electrical or electronic circuits for controlling the valves are arranged. Such a circuit board enables a highly integrated arrangement of the valve block together with the corresponding control electronics. Alternatively or additionally, according to another preferred embodiment, at least one pump, preferably a pump operated with a piezoelectric actuator or with a dielectric actuator, can be arranged on the circuit board. This enables additional miniaturization of the components and saves installation space, since a separate pump does not need to be provided on the module carrier. Such a pump, which is also arranged there, can also be controlled by the control electronics arranged on the circuit board.

[0018] Because the module carrier is a component with static and / or dynamic loads when the vehicle is running, it deforms during use. In particular, when the valve block carries sensitive components, it must be ensured that the deformation of the module carrier does not affect the function of the valve block. For example, when forming a valve block with a circuit board, excessive deformation may cause damage to the circuit board (breakage) or damage to the control electronics. Therefore, according to the utility model, according to a preferred embodiment, at least one compensation device area is formed between the module carrier and at least one integrated part of the housing, or in at least one integrated part. The compensation device area is responsible for reducing or avoiding the deformation of the module carrier and / or the contact between the module carrier and the valve block that can be installed in the housing. This can be achieved in different ways, for example, corresponding free spaces can be formed inside the housing, and when the module carrier is deformed, the valve block or parts of the housing can move into these free spaces, and the valve block itself does not contact the housing material. Another example of a compensation device area is the gap between the circuit board of the valve block and the module carrier. The gap can be empty or can be a compensation device element, which is an independent element or can be integrated in the module carrier. Of course, these compensation means regions can also be relatively soft components which at least partially absorb the forces exerted by the module carrier on the housing due to deformations. Finally, the housing can have compensation means regions in the form of reinforced regions, in which, for example, the walls of the housing are reinforced, so that deformations of the module carrier are not converted or are only converted to a small extent into deformations of the housing.

[0019] Other components can also be pre-installed on the corresponding module carrier in the module carrier assembly according to the utility model. In particular, in order to supply voltage to the valve block, in particular the connection part can be integrated in the module carrier. For example, it is preferably provided that the electrical connection component for electrical connection to the valve block, preferably a plug or a plug interface, is integrated in the module carrier. For example, such a connection component or a power supply line can be molded into the module carrier when the module carrier is manufactured.

[0020] Finally, the utility model relates to a vehicle seat having a seat frame structure and the above-described module carrier assembly suspended on the seat frame structure by a suspension device. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] exist Figure 1 and Figure 2 A diagram showing an exemplary structure of a module carrier assembly M according to the present invention can be seen in FIG. Figure 1 In the figure, Figure 2 The combination diagram is shown in the figure.

[0026] The module carrier 1 has a front side A and a back side B. Usually, the front side A faces the direction of travel of a vehicle seat (not shown) equipped with the module carrier assembly M according to the utility model. The module carrier 1 can then be mounted on the seat frame structure of the vehicle by means of a suspension device, which in the simplest case is a metal wire or the like.

[0027] The module carrier 1 is preferably made of a material preferably comprising plastic, film or felt. The module carrier 1 usually has a ventilation duct 20 fixed thereon, which is part of a pneumatic system, which can, for example, include a fluid actuator or other pneumatic components, such as a valve block 35 and / or a pump 5.

For example, a fluid actuator not shown here, which is preferably arranged on the front side A, can be connected to the ventilation duct 20. The fluid actuator is preferably a fluid-filled bag, with the help of which a seat adjustment function or a massage function can be realized. These fluid actuators also form part of the pneumatic system and can be connected to ventilation ducts present in the module carrier 1 and / or another component 3, thereby being supplied with air together. Then, a seat cushion, which is also not shown, can be installed on the front side A above the fluid actuator. For example, a pump can be connected to the ventilation duct 21, and the pump is shown here with the reference numeral 5 only in the form of its housing.

[0029] exist Figure 1 In the exploded view of the module carrier assembly according to the present invention shown in , a first housing part 31 having an internal space 31a can be seen, the first housing part 31 being integrated here on the back side B in the module carrier 1. The wall of the housing part 31 is designed to be integral with the module carrier 1. The housing part 31 is used to accommodate a valve block 35, which has a series of valves 37, 38, which are arranged on a circuit board 36 and are electrically connected to a control circuit 39. The valves 37, 38 have fluid connections 33c and 34c, which must be connected to the corresponding fluid lines 21 and 20 on the module carrier 1. For this purpose, the connections 33b and 34b corresponding to the fluid lines 21 and 20 are arranged in the area of ​​the first housing part 31 on the module carrier 1, the connections 33b and 34b being preferably designed as connection blocks, wherein the connections 33b or 34b are respectively connected to one of the fluid lines 21, 20 in a fluid-conducting manner. In addition, in Figure 1 The module carrier assembly shown in FIG. 3 comprises at least one second housing part 32, which can be connected to the first housing part 32 for encapsulating the valve block 35. For the connection, different possibilities of connecting sections or connecting elements are conceivable, preferably by realizing a clamp connection 36a, 36b for tool-free connection, wherein when the two housing halves 31, 32 are connected to each other, a locking projection 36a, preferably arranged on the part 32, is received in a corresponding locking receptacle 36b, preferably arranged on the part 31.

[0030] Further connecting sections 33a, 34a, which can, for example, also be designed as part of the housing wall of the housing 31, 32, are preferably designed as fluid pipelines in the example shown and can be plugged into a connection 33c or 33b on the valve block of the module carrier 1 and a connection 34c or 34b on the valve block 35 via a plug-in connection.

[0031] exist Figure 1 and Figure 2In the embodiment shown in FIG. 1 , the valve block 35 is first placed in the inner space 31a of the housing part 31, and then the connecting sections 33a and 34a as described above are connected to the connecting parts 33c, 33b and 34c, 34b, and finally the housing is closed by placing the housing part 32. Then, the valve block 35 is placed in the inner space 31a of the housing part 31, and then the connecting sections 33a and 34a as described above are connected to the connecting parts 33c, 33b and 34c, 34b. Figure 2 The overall assembly can be performed in a tool-free manner and can therefore be performed relatively simply.

[0032] The module carrier assembly according to the invention thus enables the components of the pneumatic system to be partially integrated in the module carrier in any case. This saves components because at least some of the pneumatic components are formed by the module carrier itself or the material of the module carrier.
