Description

[0001] Seating system for a motor vehicle and procedures

[0002] The invention relates to a seating system for a motor vehicle according to claim 1. Furthermore, the invention relates to a method for manufacturing such a seating system according to claim 10.

[0003] WO 2014 / 085 907 A1 discloses a vehicle seat element which has a foam substrate which has an A-surface for contact with an occupant and a B-surface opposite the A-surface, wherein a central part of the A-surface has a first surface area and has a plurality of channels.

[0004] The object of the invention is to create a seating system for a motor vehicle and a method for manufacturing such a seating system, so that seating comfort can be increased in a particularly low-effort manner.

[0005] This problem is solved according to the invention by a seating system for a motor vehicle with the features of claim 1 and by a method for manufacturing such a seating system with the features of claim 10. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

[0006] A first aspect of the invention relates to a seating system for a motor vehicle. The motor vehicle is, for example, a car, in particular a passenger car. Preferably, the motor vehicle, especially in its fully manufactured state, includes the seating system.

[0007] Preferably, the seating system is to be arranged or installed in the interior of the motor vehicle. Thus, the term "seating system" can be understood to mean a seating system for the interior. The interior, which can also be referred to as the vehicle interior, is understood to mean, in particular, a passenger compartment or passenger cell. The term "seating system" can specifically refer to a vehicle seat. The seating system is designed or intended for seating at least one person, who is located, in particular, in the interior. Thus, the person is, in particular, a vehicle occupant, who can also simply be referred to as an occupant.

[0008] The seating system has at least one cushion, which can also be referred to as a seat cushion or seat pad. The cushion is, for example, part of the seat section or backrest of the seating system. In other words, the seat section or backrest is at least partially formed by the cushion. Thus, the cushion can have a seating surface intended for a person to sit on. For example, the seating surface, particularly when the seating system is installed in the vehicle, faces upwards in the vehicle's vertical direction. Alternatively, the cushion can have a backrest surface intended to support the back of a person sitting on the seating system, particularly the seat section or seating surface. For example, the backrest surface, particularly when the seating system is installed in the vehicle, faces forwards in the vehicle's longitudinal direction.

[0009] The cushion incorporates a molded foam component. This molded foam component therefore contains foam material, which can also simply be referred to as foam. In other words, the molded foam component is at least partially, and in particular predominantly or entirely, made of foam material, especially molded foam. To manufacture the molded foam component, the foam or foam material can be shaped into a specific form, i.e., molded. This process can involve expanding the foam material. The foam material can thus be expandable or expanded foam. To shape the molded foam component, the expanding foam, i.e., especially during the foaming process, can be poured in its liquid state into a mold, which can also be referred to as a tool.The molded foam part can thus be produced by injecting foam into the mold, for example under low pressure. When the foam is injected into the mold and heated, the expansion of the foam, caused for example by a blowing agent, especially in the form of a gas, fills the mold.

[0010] The molded foam component has at least one channel structure designed for climate control of the seating system, particularly for the person seated on it, and through which air flows. In other words, the channel structure is formed at least predominantly, and in particular completely, by the molded foam component, specifically by the foam material of the molded foam component. This means that the channel structure is designed as a channel structure integrated into the molded foam component. The channel structure can also be referred to as a channel system. Climate control of the seating system can be understood, in particular, as temperature control of the seating system. Thus, the channel structure can be designed or intended for heating and / or cooling the seating system. The channel structure can therefore also be referred to as seat climate control or can at least be part of a seat climate control system for the seating system.Therefore, the seating system is a vehicle seat with climate control.

[0011] The channel structure is configured, at least along a certain length, as recesses arranged on one side of the molded foam part facing the person sitting on the seat, particularly the seat surface. These recesses are specifically designed for air distribution. This means that, at least along this length, the channel structure is configured as recesses located on the side facing the person sitting on the seat. In other words, the channel structure has recesses located on the same side of the molded foam part as the seat surface or backrest.Thus, the recesses are arranged, for example, on a side of the molded foam part that faces upwards in the vehicle's vertical direction, particularly when the seat system is installed in the vehicle, or on a side of the molded foam part that faces forwards in the vehicle's longitudinal direction, particularly when the seat system is installed in the vehicle. On the side facing the person, for example, an A-surface of the molded foam part or the seat system is arranged. The recesses are thus arranged, and in particular formed, on or in the A-surface. For example, the seat system, and in particular the molded foam part, has a B-surface facing away from the A-surface. The recesses each have several changes in direction. This means that each of the recesses has several changes in direction.Thus, for example, a first depression exhibits several changes in direction, and a second depression also exhibits several changes in direction. In other words, each depression allows air to flow through it in different directions. Changes in direction can be understood, in particular, as changes in the extent, especially the main extent, of the respective depression. Thus, each depression, for example, has at least a first section and at least one second section adjoining the first section, in particular directly, which extends obliquely or perpendicularly to the first section. For example, each depression has a third section adjoining the second section, in particular directly, which extends, for example, obliquely or perpendicularly to the first and / or the second section.

[0012] Furthermore, the seating system, in particular the seat climate control, has at least one fan for conveying air through the duct structure. This means that the fan allows air to be conveyed, or is conveyed, through the duct structure, especially the recesses. In other words, the fan allows air to be conveyed into the duct structure, especially the recesses, and / or conveyed out of the duct structure, especially the recesses, and / or exhausted.

[0013] The invention is based in particular on the following findings and considerations: To achieve climate control of the seating system, air can be drawn away from the vehicle occupant (suction system) and / or blown towards the occupant (blowing system) via a fan, for example. In a conventional seating system, this requires an additional layer besides the fan and the molded foam component. This additional layer can also be referred to as an extra layer. This extra layer can typically have a hardening effect, thereby negatively impacting comfort, especially seating comfort, and making the seating system significantly more expensive and complex to handle. This extra layer, also referred to as an intermediate layer, is, for example, an air distribution layer or, in particular, a simple spacer fabric.The air distribution layer, for example, is a separate layer inserted into the foam of the molded foam component, perhaps in a kind of pocket. This layer, also known as a climate bag, can be a combination of several materials. Thus, in conventional seating systems, the channel structure, particularly the recesses, can be formed by the air distribution layer or the spacer fabric. In other words, conventional seating systems often employ complex climate control layers, intermediate layers, cut foams, spacer fabrics, or similar materials to ensure air circulation from the fan (e.g., a central fan) across the entire seat cushion. These intermediate layers can be inserted into the molded foam component and, in particular, bonded and / or laminated.This insertion, and in particular the bonding or laminating, of the intermediate layers with the molded foam part can be particularly complex, which can significantly increase manufacturing effort and especially manufacturing costs.

[0014] In contrast, the aforementioned disadvantages can be avoided by means of the seat system according to the invention. The channel structure, in particular the recesses, of the molded foam part allows for air distribution, specifically air supply to and / or air extraction from the vehicle occupant seated on the seat system, for seat climate control. This means that the channel structure, and especially the recesses, can be formed by the molded foam part itself. In other words, channels for air distribution can be implemented via the molded foam part itself. In particular, the molded foam part is fully foamed directly in the mold, especially completely.Thus, a climate pattern and / or a three-dimensional geometry (3D geometry) through which air can flow, in the form of indentations, can already be implemented in the molded foam part, particularly on the A-surface. This implementation can include ventilation holes through which the air flowing through the channel structure, especially the indentations, can be directed to the occupant seated on the seat and / or is directed away from the occupant. Furthermore, the seat according to the invention eliminates the aforementioned intermediate layer, for example, the cut foam or the climate bag with spacer fabric. Therefore, the invention aims in particular to eliminate this additional material and to achieve the channel structure, especially the indentations, with the actual molded foam part itself.This allows the molded foam component to be less expensive and, in particular, eliminates additional manufacturing steps. Thus, the manufacturing effort for producing the seating system can be kept to a minimum. Furthermore, since the conventional air distribution layer can be harder, and often much harder, than the seat foam of the molded foam component itself, the seating comfort of the seating system according to the invention can be significantly increased. The person can therefore sit particularly comfortably on the seating system.

[0015] In a further embodiment, the recesses are designed to be labyrinthine. This means that each individual recess is labyrinthine in nature and / or that the recesses together form a labyrinthine structure. The term "labyrinthine" can be understood to mean, in particular, that the recesses, or each individual recess, form a structure designed according to the principles of a labyrinth. This means that the individual recesses have a large number of changes in direction, for example, at least ten, and especially at least twenty or thirty. The individual recess can thus meander through the seating arrangement, particularly on surface A. This allows for particularly effective climate control, thereby significantly increasing seating comfort.

[0016] In a further embodiment, the recesses are provided for in the foam material of the molded foam part, either already cut or being cut. This means that at least the recesses of the channel structure are formed, or being formed, by cutting. In other words, the recesses are cut recesses. This allows the recesses to be produced with minimal effort, thus enabling a particularly cost-effective manufacturing process for the seat. Furthermore, the manufacturing quality of the molded foam part, especially the channel structure, can be significantly improved.

[0017] In a further embodiment, the channel structure is or will be formed integrally with the base body of the molded foam part. This means that the channel structure and the base body are formed from a single piece, for example, a monoblock. Thus, the channel structure and the base body are not separate components. In other words, the molded foam part is free of any additional foam material beyond that which forms the channel structure. Therefore, the molded foam part does not contain any additional foam material. This means that the molded foam part is entirely formed by the foam material that also forms the channel structure, particularly the recesses. Specifically, the molded foam part is formed in one piece.This allows the seating system to be manufactured with minimal effort, since, for example, only a single molded foam part needs to be produced, which can be used to create the channel structure, for example by the aforementioned cutting.

[0018] In an alternative embodiment, the molded foam part comprises a base body, which can also be referred to as a support body. The base body defines a receiving space, at least partially, and in particular predominantly or completely. Furthermore, the molded foam part includes at least one insert, separate from the base body, which is arranged in the receiving space and has at least the recesses of the channel structure. In other words, the insert is received in the receiving space, specifically, it is placed within the receiving space, with at least the recesses of the channel structure being formed, in particular at least predominantly or completely, by the insert. Thus, the recesses of the channel structure are not formed by the base body, which can therefore be free of the recesses.The insert can therefore be a separate foam component, for example in the form of a foamed cassette, which can be produced separately from the base body. This allows the recesses to be manufactured separately from the base body, enabling, for example, the implementation of different design variants, particularly equipment variants, of the seating system, especially in motor vehicles, in a particularly cost-effective manner. The base body can be used across different design variants or equipment variants, with, for example, only higher-end equipment variants featuring the insert and thus this climate control system.

[0019] In a further embodiment, the cushion is provided to have a seat cover, which is formed separately from the molded foam part, by means of which the molded foam part is at least partially, in particular predominantly or completely, surrounded, especially at least on the side facing the person sitting on the seat. In other words, the seat cover surrounds the molded foam part at least partially, in particular predominantly or completely.

[0020] For example, the seat cover has at least one layer, which is formed, for example, by leather, fabric, a fabric-like material, imitation leather, or the like. This means that the layer is made of, for example, leather, imitation leather, fabric, velvet, or the like. This layer can therefore be a leather layer, an imitation leather layer, a velvet layer, or a fabric layer. For example, the seat cover has a second layer, separate from this layer, which can also be called the first layer, and which is made, for example, of textile, that is, a textile material. The second layer can therefore also be called the textile layer. The first layer is, for example, located on the outside of the upholstery, especially the seat. In particular, the second layer is located on the inside of the upholstery, adjacent to the first layer.Thus, the second layer can be positioned between the first layer and the molded foam component. In a further embodiment, the seat cover is provided with openings through which air can flow, or through which air flows, and which are fluidically connected to the channel structure, particularly the recesses. The air flowing through the channel structure, especially the recesses, can be supplied to and / or extracted from the person sitting on the seat, particularly for climate control purposes, via these openings. This allows the person to be directly exposed to the air, resulting in a particularly effective climate control effect.

[0021] In a further embodiment, the seating system is designed to be free of a separate foam layer and / or foam-like layer located between the molded foam component and, in particular, the seat cover. This means that no foam—that is, no additional foam relative to the molded foam component—and / or no foam-like material is located between the seat cover and the molded foam component. Thus, only the seat cover rests on the molded foam component, specifically on the recesses formed by the molded foam component. In other words, the seat cover rests directly on the recesses or on a portion of the molded foam component that forms the recesses. This allows for a particularly low material requirement for the seating system, enabling its production to be very cost-effective.The term "foam-like layer" can be understood to refer specifically to a material that exhibits similar properties, particularly comfort characteristics, to foam. This foam-like material can be described as a foam substitute.

[0022] In an alternative embodiment, a comfort layer, which can also be referred to as an additional layer, is arranged between the seat cover and the molded foam component. This comfort layer is formed separately from the molded foam component and, in particular, separately from the seat cover. In other words, the comfort layer extends, at least partially, between the seat cover and the molded foam component. The comfort layer is, for example, a foam layer made of a softer foam than the molded foam component. In other words, the foam layer is softer than the molded foam component. This means that the material of the foam layer is softer than the material of the molded foam component. As a result, the cushion can be made particularly soft for the person sitting on the seat, thus significantly increasing seating comfort.Alternatively, the comfort layer can be made of a foam substitute material, which can also be described as a foam-like material.

[0023] A second aspect of the invention relates to a method for manufacturing a seating system according to the first aspect of the invention. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention, and vice versa.

[0024] In particular, the process creates the channel structure of the molded foam part. Specifically, the recesses are formed, for example, by cutting. These recesses can then be cut into the foam material of the molded foam part. This means that channels intended for airflow can be cut into the foam of the molded foam part.

[0025] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own.

[0026] The invention will now be explained in more detail with reference to a preferred embodiment and the drawings. The drawings show:

[0034] Seating system according to a further embodiment.

[0035] In the figures, identical or functionally equivalent elements are provided with the same reference symbols.

[0036] Fig. 1 shows a schematic and perspective partial view of a seat assembly 1 for a motor vehicle. In this embodiment, the seat assembly 1 has a seat section 2, which includes a seat surface 3 designed for one person. The seat surface 3 is oriented upwards in the vehicle's vertical direction 4. Furthermore, in this embodiment, the seat assembly 1 has a backrest 5, which can also be referred to as a second seat section. In this embodiment, the seat section 2 and the backrest 5 are formed separately from each other. Alternatively, it is possible for the seat section 2 and the backrest 5 to be formed as a single piece, particularly if the seat assembly 1 is designed as an integral seat. The backrest 5 has a support surface 6 for the person sitting on the seat assembly 1 to lean against, which in this embodiment is oriented forwards in the longitudinal direction 7 of the vehicle.

[0037] In this case, the seat section 2 has one cushion 8, and the backrest 5 has a second cushion 9. At least one of the cushions 8, 9 has a molded foam component 10. Thus, at least one of the cushions 8, 9 can be designed as a molded foam component 10. Therefore, the seating arrangement 1 can, for example, have one molded foam component 10 or two molded foam components 10: the molded foam component 10 of cushion 8 (i.e., the molded foam component 10 of the seat section 2) and / or the molded foam component 10 of the second cushion 9 (i.e., the molded foam component 10 of the backrest 4). One of these molded foam components 10 will be explained below as an example. The molded foam component 10 can therefore refer to either the molded foam component of cushion 8 and / or the molded foam component of cushion 9.

[0038] Fig. 2 shows the molded foam part 10 in a schematic and perspective partial view. The molded foam part 10 has a channel structure 11 for air conditioning, in particular for cooling and / or heating, the seating system 1, and through which air flows or is flowing. The channel structure 11 has recesses 14 arranged on at least one side 13 of the molded foam part 10 facing the person sitting on the seating system 1, at least in a length 12. Thus, side 13 is, for example, a side facing upwards in the vehicle's vertical direction 4 and / or forwards in the vehicle's longitudinal direction 7. The side facing the person sitting on the seating system 1 can be understood, in particular, to mean that side 13 is facing towards the person when the person is sitting on the seating system 1. The recesses 14 are also shown, for example, in Fig.Figure 3 shows a schematic illustration of the molded foam part 10 according to a further embodiment. The respective recess 14 is, for example, designed as a groove. The term "respective recess 14" can be understood to refer in particular to a partial area of ​​a foam material 15, wherein this partial area extends between any two of the respective recesses 14. The recesses 14 each have several changes of direction. In the exemplary embodiment, the recesses 14 are designed in a labyrinthine manner.

[0039] The recesses 14 may or may not intersect. This means that the channel structure 11 can be free of intersections, i.e., of intersecting recesses 14. In particular, the embodiment provides that the changes in direction are not formed by intersections of the recesses 14. Thus, for example, each recess 14 has at least one sub-area that is free of intersections, i.e., points of intersection, with the other recesses, i.e., with at least one of the other recesses 14, and that at least this sub-area has several changes in direction, for example, at least two, five, ten, or twenty. The recesses 14 can also be referred to as channels.In the present case, the recesses 14, in particular exclusively, on side 13, for example in the vehicle vertical direction 4 upwards and / or in the vehicle longitudinal direction 7 forwards, are designed to be open.

[0040] Fig. 4 shows the seating assembly 1, in particular the molded foam part 10, in a schematic partial sectional view. As can be seen in Fig. 4, the seating assembly 1 has a fan 16 for conveying air through the channel structure 11, and in particular the recesses 14. The fan 16 can be understood to be, in particular, a blower. For example, the fan 16 is an electric fan. For example, the fan 16 is designed as a ventilator.

[0041] By means of the fan 16, air can be transported via the duct structure 11, and in particular via the recesses 14, to the person seated on the seat 1 and / or the air can be extracted from the person seated on the seat 1. This allows a comfortable climate to be created for the person, in particular by heating and / or cooling. Thus, the vehicle occupant seated on the seat 1 can be exposed to air, for example for cooling purposes, as illustrated by arrows 11a in Fig. 1. Furthermore, the air can be extracted from the vehicle occupant, as illustrated by arrows 11b in Fig. 1.The channel structure 11 formed by the molded foam part 10 itself, particularly the recesses 14, enables the aforementioned transport, especially air distribution within the seating system 1, by means of the molded foam part 10. This eliminates the need for a separate air distribution layer, thus significantly reducing assembly costs. Furthermore, parts handling during the manufacturing of the seating system 1 is greatly improved, further minimizing manufacturing effort. In particular, the air within the molded foam part 10 can be distributed directly, for example, by creating a labyrinthine design within the molded foam part 10. Eliminating the air distribution layer also significantly improves seating comfort, as the molded foam part 10 is typically more comfortable, especially softer, than a conventional air distribution layer.

[0042] Preferably, the channel structure 11, and in particular the recesses 14, are cut into the foam material 15 of the molded foam part 10. The foam material 15 can therefore be cut foam. The foam material 15 is, for example, expanded polypropylene, expanded polystyrene, or polyurethane. In particular, the foam material 15 is not corrugated foam. This means that the foam material 15, and thus in particular the molded foam part 10, is free of corrugated foam or corrugated foam material 15.

[0043] Preferably, the channel structure 11, and in particular the recesses 14, are formed integrally with a base body 17 of the molded foam part 10. This can be seen particularly well, for example, in Fig. 2 and Fig. 4.

[0044] Alternatively, the molded foam part 10 may have an insert 18, i.e., it may be partially formed separately by the insert 18. The insert 18 is shown in Fig.

[0045] The embodiment shown in Fig. 3 represents the following. The insert 18 is formed separately from the base body 17. The base body 17 at least partially defines a receiving space in which the insert 18 is to be arranged. In the embodiment shown in Fig. 3, the insert 18 has at least the recesses 14, particularly with respect to the base body 17 and the insert 18 exclusively.

[0046] As shown in Fig. 4, in the exemplary embodiment, each cushion 8, 9 has a seat cover 19, in particular a seat cover 19, by means of which the molded foam part 10 is at least partially, in particular predominantly or completely, covered. The seat cover 19 is intended for direct contact with the person sitting on the seat 1. For example, the seat cover 19 is at least partially made of fabric, i.e., a fabric cover, or of leather, i.e., a leather cover, or of imitation leather, i.e., an imitation leather cover, or of velvet, i.e., a velvet cover, or the like. For example, a first layer, in particular an outer layer, of the seat cover 19 is made of the fabric or the leather.For example, the seat cover has a second layer, in particular an inner layer, wherein this second layer can, for example, be a textile layer, that is, at least partially made of a textile. For example, the seat cover 19 has openings through which air can flow and which are not shown in the figures, in particular through-openings, which can be fluidically connected to or are connected with the channel structure 11, in particular with the recesses 14. The openings can be understood in particular as holes, for example in the form of a hole pattern, through which the person sitting on the seat 1 can be supplied with air, in particular controlled.

[0047] In the embodiment shown in Fig. 4, the seat assembly 1 is free of a foam layer formed separately from the molded foam part 10 and arranged between the molded foam part 10 and the seat cover 19. Thus, the seat cover 19 rests, for example, and in particular directly, on the molded foam part 10, and therefore, in particular, at least partially on the recesses 14. Thus, the seat cover 19 can rest, in particular directly, on a structure of the molded foam part 10 that forms the recesses 14. In particular, there is no foam between the seat cover 19, in particular the first and / or the second layer, and the molded foam part 10.

[0048] Figure 5 shows a schematic partial sectional view of the seat 1 according to a further embodiment, in which a comfort layer 20, formed separately from the molded foam part 10, is arranged between the seat cover 19 and the molded foam part 10. This comfort layer 20 is, for example, formed as a foam layer made of a softer foam than the molded foam part 10. This foam layer, which can also be referred to as an additional foam layer, forms the comfort layer 20, allowing the person to sit on the seat 1 in a particularly soft and comfortable manner. The foam layer comprises, for example, at least one layer of foam, such as cut foam. The cut foam is, for example, a cut layer of soft, particularly very soft, foam. Alternatively, the comfort layer 20 is formed, for example, from a foam substitute material.

[0049] In the embodiment shown in Figures 4 and 5, the channel structure 11 has channels 21 that are fluidically connected or connectable to the recesses 14 and which, in this case, extend perpendicular to the recesses 14. For example, air can be conveyed to the recesses 14 via the channels 21 by means of the fan 16. Alternatively or additionally, air can be conveyed from the recesses 14 to the fan 16 via the channels 21. In particular, if the molded foam part 10 is designed as a molded foam part 10 of the seat part 2, the air can be transported upwards via the channels 21, at least substantially, in the upward direction 4 of the vehicle.
