Description

Technical Field

[0001] This application relates to a method of manufacturing a seat structure and a seat structure for an automobile seat, as well as an assembly, a kit, and an automobile seat. The automobile may be a road vehicle, particularly a passenger car, truck, or bus. Background Technology

[0002] Car seats typically have a rigid seat structure with flexible cushioning elements mounted on it to ensure seat comfort. This seat structure may include, for example, metal components. These metal components stably hold and support the vehicle occupant seated in the car seat. An example of a seat structure can be found in DE 102004 049 191A.

[0003] Furthermore, it is known to install various additional components on the seat structure, which, for example, provide functions independent of the actual seat function and / or additional comfort features within the range of seat functions. Examples of such components include a fire extinguisher or its bracket and a selectively extendable leg rest.

[0004] The specific requirements depend on whether and which additional components need to be installed on the seat structure; currently, a dedicated seat structure must be manufactured for this purpose. This results in higher manufacturing difficulty and correspondingly higher costs.

[0005] In addition, this seat structure must be able to reliably withstand greater forces during emergency braking and / or a collision, even with different additional components installed on it. Utility Model Content

[0006] Therefore, the aim is to provide a stable seat structure for reliably mounting additional components, which is limited in terms of manufacturing difficulty and cost, especially considering the many additional components that may be installed and the variety of related variations.

[0007] The solution used in this application to achieve the above-mentioned objectives is the subject matter of the independent claims. Advantageous improvements are given in the dependent claims, this specification, and the accompanying drawings.

[0008] Accordingly, a seat structure for automobile seats is proposed, wherein the seat structure has:

[0009] A crossbeam positioned near the front edge of the car seat, or positioned near the front edge of the car seat.

[0010] The first side portion connected to the first end region of the crossbeam,

[0011] The second side portion connected to the second end region of the crossbeam,

[0012] First support assembly and second support assembly

[0013] The first support assembly and the second support assembly respectively have:

[0014] A support element having a fixing section for securing at least one additional component or (in other words) another additional component.

[0015] A clamping element, which secures the crossbeam to the support element while at least segmenting it between the support element and the clamping element.

[0016] The support element of the first support assembly is fixed on the first side, and the support element of the second support assembly is fixed on the second side.

[0017] This solution is characterized by high stability because these support assemblies are fixed both to the sides and to the crossbeams. Therefore, even under increased emergency braking forces and / or impact forces, the additional components can be reliably supported by the seat structure.

[0018] Furthermore, the support assemblies are secured in the form of side sections and crossbeams in easily accessible areas of the seat structure, specifically on components typically located on the outer sides and / or forward in the forward direction. This correspondingly reduces installation difficulty. These support assemblies can be easily retrofitted and / or modularly supplemented depending on the desired seat variant.

[0019] The disclosed solution, in particular, allows for the flexible installation of different add-ons onto the same seat structure without requiring adaptation of the seat structure to specific add-ons. Therefore, the same seat structure can preferably be combined with different add-ons to achieve increased variability and modularity. However, the seat structure can also preferably be used without the support assembly and add-ons installed on it.

[0020] Advantageously, different additional components can be installed on the same support assembly, specifically on its fixed section. This fixing can be detached and / or at least not through material bonding. This also allows for greater variability and modularity with reduced installation difficulty.

[0021] The crossbeam may extend along the width of the vehicle. The crossbeam may be cylindrical and / or elongated. According to one variant, the crossbeam is tubular. If it is assumed that the seat structure is already installed in a car seat, particularly in combination with possible cushioning elements, the crossbeam may be positioned near the front edge of the car seat. In the uninstalled state, the crossbeam may be correspondingly described as being positioned near the front edge.

[0022] The crossbeam may extend from one side and / or the first edge region of the seat structure and / or the vehicle seat to the second side and / or the second edge region. Its length may be at least 75% of the width dimension of the seat structure and / or the vehicle seat.

[0023] These sides can be, for example, sheet metal components and / or plate-like components. They can extend at an angle to the longitudinal axis of the crossbeam, particularly substantially perpendicular to that longitudinal axis. These sides can extend, for example, along the longitudinal direction of the vehicle and / or the longitudinal dimension of the seat surface of the car seat. These sides can be mounted on the floor rails of the car and / or connected, particularly directly, to components of the car seat that can be mounted on such floor rails.

[0024] The car seat may have a seat surface and a backrest. It is well known that the seat surface and the backrest may be oriented at an angle relative to each other. The seat surface and the backrest may each include or be constituted by at least one cushioning element.

[0025] The seat surface may have a leading edge, which, for example, forms a forward-facing area of ​​the car seat and / or seat surface in the forward direction. The seat surface may have a first edge region and a second edge region, extending from a position on or near the backrest to the leading edge of the seat surface, respectively. As described above, these sides may extend along and / or overlap with these edge regions. The crossbeam may extend along and / or overlap with the leading edge.

[0026] The support elements may be sheet metal components, particularly bent, formed, and / or stamped components. Alternatively, these support elements may be manufactured, for example, by injection molding and / or made of plastic. According to one variant, these support elements are angled components having a first segment extending at least segmentally along the sides, particularly parallel to these sides. A second segment extends at an angle to the first segment and may have a fixed segment.

[0027] The fixing section can be, for example, a plate-like and / or planar area. Viewed in the forward direction, the fixing section can be positioned upstream of the side and / or crossbeam. Alternatively or supplementarily, the fixing section can be positioned closer to the crossbeam and / or the front edge of the seat than the backrest. This allows additional components fixed to the fixing section to be positioned in a correspondingly upstream area that is easily accessible to vehicle occupants.

[0028] The fixing section is characterized by at least one prefabricated interface for mechanically securing the additional components. This interface may, for example, include at least one drilled hole, at least one through hole, and / or at least one engaging structure. This correspondingly reduces the installation time for mounting the additional components onto the seat structure and simplifies the installation of different additional components when these additional components are compatible with the prefabricated fixing interface.

[0029] The clamping element may not have a fixed section for mounting additional components. Aside from its clamping function, the clamping element cannot provide any other functionality. The size of the clamping element can be smaller than the support element, for example, its length not exceeding half or a quarter of the support element, wherein the corresponding length can be measured in the forward movement direction while mounted on the seat structure. This improves the portability of the clamping element and reduces its manufacturing cost.

[0030] The first and second support assemblies can be constructed in the same manner. Alternatively or supplementarily, the first and second support assemblies can be oriented and / or constructed in a manner that is mirror-symmetrical to each other. The latter case may involve at least the support elements, while the clamping elements can be constructed in the same manner. This correspondingly reduces the number of parts and simplifies installation. The mirror-symmetrical plane may contain the forward movement direction and / or longitudinal axis of the car seat. As a supplement or alternative, this plane may extend centrally through the crossbeam and / or seat surface and / or backrest. This plane may be vertical.

[0031] In principle, these support elements and / or these clamping elements can be fixed to the sides or support elements in a non-removable manner. However, such a non-removable connection is preferably achieved mechanically, for example by rivets, and particularly by non-material bonding. However, according to the embodiments discussed below, the fixing of the aforementioned elements is preferably removable.

[0032] Any resolvability mentioned herein may include, for example, the reversibility of connections between components that can be reversibly disengaged and / or re-established without damaging the components and / or the connectors used. Any non-resolvability mentioned herein may include, for example, the reversibility of connections between components that cannot be reversibly disengaged and / or re-established without damaging the components and / or the connectors used.

[0033] According to one embodiment, the support element is detachably and / or non-materially bonded (or in other words, unmaterially bonded) fixed to a respective side of the first and second sides. These support elements are fixed to the respective sides, for example, mechanically, particularly by means of a screw connection. However, these support elements are not, for example, welded or brazed to the respective sides.

[0034] As alternative or supplementary elements, the clamping elements are detachably and / or non-materially bonded to the respective support elements. These clamping elements are fixed to the respective support elements, for example, mechanically, particularly by means of a screw connection. However, these clamping elements are not, for example, welded or brazed to the respective support elements.

[0035] The clamping and supporting elements can be mechanically connected to each other and / or fixed to the crossbeam. This is achieved, in particular, by the clamping action created by housing the crossbeam between these elements. This connection is preferably not achieved through material bonding, and in particular, not by welding or brazing. This also helps to reduce installation difficulty and related costs.

[0036] As described above, any releasable fasteners disclosed herein can in particular include mechanical fasteners, such as screwing and / or clamping. This can be achieved, in particular, by holding the components together between a shear bolt and a nut, thereby clamping them together. Components can also be tensioned together by screwing, and then the clamping force is transmitted to the assembly housed between these components. The latter specifically relates to the fastening of clamping and supporting elements on a beam that can be mechanically fastened to each other, particularly by screwing.

[0037] According to one embodiment, the support element is arranged opposite to, and particularly arranged on, the inner side of a corresponding side in the first and second sides, and is fixed to, the inner side. This improves the compactness of the resulting overall configuration. The inner side may also be unused or occupied, or at least not fully used or occupied. Arranging it on the inner side particularly eliminates the need for separate adaptation of the seat structure and / or vehicle seat, depending on whether the support assembly disclosed herein is installed. This further helps reduce installation difficulty and cost and increases variability without requiring variant-specific adaptations to the seat structure.

[0038] As described above, according to one embodiment, the support element can be fixed to a corresponding side of the first and second sides by a screw connection.

[0039] According to one embodiment, the support element and / or the clamping element have receiving surfaces shaped in a complementary manner to the outer side of the crossbeam. The curvature of these surfaces can, in particular, be designed in a complementary manner. The outer side of the crossbeam can, for example, be convexly curved, and the receiving surfaces can be concavely curved. This complementary design of the receiving surfaces relative to the outer side of the crossbeam allows for large-area contact between the receiving surfaces and the crossbeam, thereby achieving a particularly reliable fixing effect, especially a clamping effect.

[0040] The clamping and supporting elements typically extend together along and / or abut against a portion of the outer perimeter of the crossbeam, said portion comprising at least 50% of the entire perimeter. As supplementary or alternative elements, each of the clamping and supporting elements may extend along and / or abut against at least 25% or at least 40% of the outer perimeter of the crossbeam. This perimeter can be particularly viewed in a cross-sectional plane perpendicular to the longitudinal axis of the crossbeam.

[0041] According to one embodiment, the support element is opposite to and / or abuts against the bottom side of the crossbeam. Alternatively or supplementarily, the clamping element may be opposite to and / or abut against the top side of the crossbeam. The top side of the crossbeam may be vertically positioned above the bottom side. The bottom side may face the vehicle floor. The top side may face away from the vehicle floor. Installation is simplified by arranging the clamping element and support element accordingly on the bottom or top side, as smaller clamping elements typically do not, or only partially, cover the support element from above. This also allows for a compact structure, as the fixing section and / or additional components to be mounted thereon can typically be vertically positioned below the crossbeam. In this embodiment, the support element is arranged on the bottom side of the crossbeam from the outset, thus being relatively deep, resulting in a compact structure.

[0042] According to one embodiment, the support element and the clamping element engage with each other. This engagement can be achieved, in particular, before and / or during the fixing of the support element and the clamping element to each other. As a supplement or alternative, this engagement can be achieved substantially simultaneously with and / or before accommodating the beam between the support element and the clamping element. This engagement may include: one of the support element and the clamping element having an engagement section, particularly a protruding section, which is accommodated in a accommodating section of the corresponding other of the support element and the clamping element, particularly in the case of a form fit. The accommodating section may, for example, include a notch, such as a drilled hole, groove, or slot. The engagement section may, for example, protrude toward, the corresponding other of the support element and the clamping element, particularly bend or flex in that direction.

[0043] By implementing the corresponding engagement, these components can be reliably positioned relative to each other in a predetermined manner when or before they are secured to the crossbeam. This simplifies installation and reduces the possibility of errors.

[0044] The support element and the clamping element may have a region and / or a location in which, or on which, the support element and the clamping element are fixed to each other. This region or location may, for example, include at least one drilled hole into which a mechanical fixing element (particularly a shear bolt) for fixing the elements to each other can be inserted.

[0045] According to one embodiment, the support element and the clamping element are fixed to each other at a position more than 2 cm and / or no more than 5 cm from the crossbeam. This distance can be measured, for example, perpendicular to the longitudinal axis of the crossbeam and / or perpendicular to the longitudinal axis of the fixing element, by means of the fixing element. This distance provides a lever arm, thereby converting the fixing force generated by the fixing element into a correspondingly increased clamping force on the crossbeam. Limiting the maximum distance also improves compactness.

[0046] According to one embodiment, each of the fixing sections has at least one through-hole for fixing additional components, particularly for accommodating fixing elements used to achieve such fixing. In this way, these fixing sections can provide a prefabricated and / or standardized mechanical interface for fixing different types of additional components.

[0047] This application also relates to an assembly having:

[0048] According to the seat structure described in any of the aspects disclosed herein;

[0049] Additional components fixed to at least one fixed section of the seat structure.

[0050] The additional component may in particular be one of the following:

[0051] The seat cushion longitudinal adjustment device, in particular including a guide structure by means of which the distance between the individual cushion elements can be changed, wherein the cushion elements are surrounded by the seat surface of the car seat;

[0052] A leg rest, or in other words, a leg support, is especially in the form of a selectively retractable surface on which a person sitting in a car seat can place their legs, and the surface typically contacts the person's lower legs;

[0053] The leg rest longitudinal adjustment device, in particular, includes a guide structure by means of which the distance between the various support elements can be changed, wherein the support elements are surrounded by the support surface of the leg rest;

[0054] Storage devices, particularly in the form of fixed boxes and / or foldable, collapsible or foldable containers;

[0055] Fire extinguisher and / or its stand,

[0056] Umbrellas, especially folding umbrellas,

[0057] Lights, especially flashlights.

[0058] This application also relates to a kit for manufacturing at least a portion of a seat structure according to any aspect disclosed herein, said kit comprising a first support assembly and a second support assembly. This kit may, for example, exclude the crossbeams and / or sides and accordingly only manufacture a portion of said seat structure. This portion may be a modularly supplementary component including these support assemblies, wherein the portion allows for easy installation of various additional components.

[0059] This application also relates to an automobile seat comprising a seat structure and / or an assembly as disclosed in any aspect herein.

[0060] Finally, this application also relates to a method of manufacturing a seat structure for automobile seats, wherein the seat structure has:

[0061] A crossbeam positioned near the front edge of the car seat, or positioned near the front edge of the car seat.

[0062] The first side portion connected to the first end region of the crossbeam,

[0063] The second side portion connected to the second end region of the crossbeam,

[0064] First support assembly and second support assembly

[0065] The first support assembly and the second support assembly respectively have:

[0066] A support element having a fixing section for securing at least one other additional component.

[0067] Clamping components,

[0068] The method includes:

[0069] The support element of the first support assembly is fixed to the first side, a section of the crossbeam is accommodated between the clamping element and the support element of the first support assembly, and the clamping element and the support element are fixed to each other.

[0070] The support element of the second support assembly is fixed to the second side, a section of the crossbeam is accommodated between the clamping element and the support element of the second support assembly, and the clamping element and the support element are fixed to each other.

All descriptions and modifications of the features of the seat structure disclosed herein may also be applied to the method features with the same wording. Attached Figure Description

[0076] Figure 4 To and Figure 2 Another view of the assembly status of similar components. Detailed Implementation

[0077] Figure 1 A portion of the seat structure 10 of the car seat 12 is shown. The car seat 12 is not yet in an installable state because, in particular, its cushioning element is missing. Figure 1 The portion shown specifically includes a part of the car seat 12, which comprises the seat surface after the seat is assembled. The portion that serves as the backrest after the seat is assembled is not shown separately.

[0078] The seat structure 10 includes two sides 14 and 15 extending along the outer edge region or outer side and along the longitudinal direction L of the vehicle seat 12. This longitudinal direction L coincides with the forward movement direction of the vehicle on which the vehicle seat 12 is mounted or to be mounted. Sides 14 and 15 are sheet metal components, optionally having notches and / or recesses and / or formed or stamped profiles, but are substantially plate-shaped. However, sides 14 and 15 may also be made of plastic.

[0079] The seat structure 10 also includes a crossbeam 16. This crossbeam extends between sides 14 and 15 and is preferably mechanically connected to each of the sides 14 and 15. Specifically, the crossbeam 16 includes two back-to-back end regions 17 and 19 opposite each other along its longitudinal axis A. Each side 14 and 15 is mechanically connected to one of the end regions 17 and 19, for example by means of an interference fit and / or a form-fit connection commonly referred to as tube end forming. In the latter case, the ends of the crossbeam 16 are formed in a way that creates radially projecting stop surfaces, and a section of the respective side 14 and 15 is accommodated and / or formed between these stop surfaces. The accommodated section can be fitted onto an undeformed or at least slightly deformed section of the crossbeam 16 and, for example, accommodated or enclosed in a recess. Alternatively or supplementary, a material-jointed connection, particularly a welded connection, can also be achieved between the sides 14 and 15 and the end regions 17 and 19.

[0080] Furthermore, the crossbeam 16 extends at an angle to the longitudinal axis L, specifically perpendicular to it. This is evident from the longitudinal axis A of the crossbeam 16. Figure 1 As can be seen from the position shown, in the example shown, the crossbeam 16 is tubular. The crossbeam 16 is arranged at the front ends of the respective sides 14 and 15 (e.g., relative to the forward direction). These front ends are located away from the sides 14 and 15 near... Figure 1 The ends of the backrest, not shown, or those opposite to these ends.

[0081] Furthermore, the crossbeam 16 is positioned on or near the front edge of the car seat 12, particularly on its incomplete seat surface. Figure 1 Compared to the backrest (not shown), the crossbeam 16 is particularly closer to the front edge.

[0082] The seat structure 10 also includes a first support assembly 18 and a second support assembly 20. The support assemblies 18 and 20 are substantially identical but mirror-symmetric to each other. The mirror-symmetric plane, not shown separately, extends vertically and includes the longitudinal axis L.

[0083] Support assemblies 18 and 20 each include a clamping element 22 and a supporting element 24. The clamping element 22 and supporting element 24 of each support assembly 18 and 20 are opposite to each other and abut against each other in segments. In this configuration, these clamping and supporting elements each accommodate a segment of the crossbeam 16 therebetween. In the illustrated example, the respective accommodated segment of the crossbeam 16 is close to or surrounded by one of the end regions 17 and 19. Furthermore, support assemblies 18 and 20 are generally also positioned close to or overlapping these end regions 17 and 19, and in particular contact with a respective side of the sides 14 and 15.

[0084] The following text will also combine Figure 2 As illustrated, the clamping element 22 and the support element 24 each have a receiving surface 40, which, in the example shown, is shaped in a manner complementary to the circular outer peripheral surface of the section of the beam 16 that is received between the respective pair of clamping elements 22 and support elements 24. In the example shown, to improve stability, the pair of clamping elements 22 and support elements 24 completely surround the outer periphery of the section of the beam 16 that is received, but this is not mandatory.

[0085] The clamping element 22 and the support element 24 of the corresponding support assemblies 18 and 20 are fixed to each other. In the example shown, this is achieved by a helical element 26, which is inserted into a drill hole aligned with each other in the clamping element 22 and the support element 24. The drill axis B corresponding to the longitudinal axis of the inserted helical element 26 is in Figure 1 As exemplarily shown, the drill axis B is perpendicular to the opening surfaces of the corresponding drill holes aligned with each other in the clamping element 22 and the support element 24.

[0086] It can be seen that the fixed positions of the clamping element 22 and the support element 24 along the drilling axis B or corresponding to the position of the helical element 26 are spaced apart by a distance D from the longitudinal axis A of the crossbeam 16 (see also). Figure 3 In the illustrated configuration, the longitudinal axis A extends centrally through the crossbeam 16, with its tubular cross-section extending concentrically around the longitudinal axis A. Distance D defines a lever arm by which the fixing force generated by the helical element 26 is converted into a correspondingly increased clamping force between the clamping element 22, the support element 24, and the crossbeam 16.

[0087] Support elements 24 are respectively arranged on and in contact with the inner sides 14 and 15. Furthermore, these support elements are fixed to the respective sides 14 and 15 by means of at least one screw 28. That is, the support elements 24 are fixed both to the crossbeam 16 and to the sides 14 and 15. This allows the support elements 24 to absorb forces with great extent and reliability, thereby significantly reducing the risk of slippage.

[0088] In the illustrated example, the support elements 24 are sheet metal components constructed in a substantially plate-like manner at least along the sides 14 and 15. These support elements extend forward, away from the sides 14, 15, and along the longitudinal axis L. Each support element 24 has a fixing section 30. In the illustrated example, the fixing sections 30 are curved relative to the adjacent areas of the respective support elements 24, such that these fixing sections provide a fixing surface facing towards and away from the vehicle floor. Due to the aforementioned extension of the support elements 24, the fixing sections 30 are located in front of the crossbeam 16 and the sides 14, 15, and particularly further away from the backrest (not shown) compared to these components.

[0089] The fixed section 30 has unidentified through holes into which fixing elements 32 for securing the attachment 34 are inserted. In the example shown, the attachment 34 is an extendable leg rest that includes various movable components not described in detail herein. Figure 1 The retracted state of the attachment 34 is shown. Other attachments 34, particularly those according to any of the examples mentioned herein, can be mounted to the fixing section 30 instead of the shown leg support without requiring separate adaptation of these fixing sections 30. Alternatively, it is sufficient if the attachment 34 has a through-hole that can be aligned with the through-hole 42 of the fixing section 30 to jointly accommodate the fastener 32.

[0090] The seat structure 10 and the additional components 34 constitute an assembly 100 of the type disclosed herein. A kit 102 of the type disclosed herein includes support assemblies 18 and 20. Such a kit 102 can, for example, be supplied to a production line for manufacturing desired seat variants. Alternatively or as a supplement, such a kit 102 can also be provided as a retrofit kit for mounting the desired additional components 34 onto an already installed vehicle seat 12.

[0091] As can be clearly seen from the above, the support assemblies 18 and 20 can be easily installed onto the existing seat structure 10, for example, through manual and / or purely mechanical installation steps, and in particular, can be added only as needed. However, the seat structure 10 can also be used without the support assemblies 18 and 20 to form an automotive seat.

[0092] The existing design of the seat structure 10 can also be used with only minor modifications (if any). These modifications may be necessary, for example, to secure the support element 24 to the sides 14, 15.

[0093] Furthermore, the support assemblies 18, 20 can be coupled with different additional components 34, thereby increasing the variety of possible variations without requiring comprehensive and / or variant-specific changes to the seat structure 10.

[0094] Finally, the support assemblies 18 and 20 are redundant and fixed to different components within the seat structure 10, thereby improving the mechanical load capacity of the seat structure.

[0095] Figure 2This is an exploded view of a portion of the seat structure 10. Specifically, the second support assembly 22, together with the crossbeam 16, is shown. The receiving surfaces 40 of the clamping elements 22 and the support elements 24 are visible in this view. These receiving surfaces are shaped in a manner complementary to the outer peripheral surface of the crossbeam 16 and can abut against this crossbeam. In the example shown, the receiving surface 40 is concavely curved and / or corresponds to a portion of a cylindrical inner surface. Furthermore, it is evident that the clamping elements 22 abut against the crossbeam 16 from above, while the support elements 24 abut against the crossbeam 16 from below.

[0096] In addition, Figure 2 You can also see the through hole 42 in the fixed section 30. Figure 1 The fasteners 32 shown for mounting the additional component 34 can be inserted into these through holes.

[0097] In addition, the drill holes 27 in the clamping element 22 and the support element 24 can be seen, which can be arranged in a way that aligns with each other along the drill axis B.

[0098] Figure 2 The protruding sections 44 on the clamping element 22 are also shown, particularly in the form of angled protrusions, hooks, and / or retaining flanges. A slit-like recess 46 is provided in the support element 24.

[0099] Figure 3 Showing the assembly state Figure 2 The diagram shows that the protruding section 44 and the recess 46 form an engaging structure 48, as the protruding section and the recess can engage with each other. This allows the clamping element and the support element to be oriented relative to each other in a defined manner during installation, particularly before the clamping element 22 and the support element 24 are secured together, and at least temporarily held together.

[0100] Figure 4 Another view of the assembled state, but with Figure 3 In comparison, this image is... Figure 3 The side view of the support element 24 opposite to the support element 24 shown. This view also clearly shows the engaging structure 48 formed by the protruding section 44 and the notch 46.

[0101] In addition, it was also marked Figure 4 The gap S is substantially closed by tightening the screw element 26. This gap largely occurs before the screw element 26 is inserted and tightened between the surfaces of the clamping element 22 and the support element 24, which face each other and are at least partially in contact. The resulting clamping force is primarily related to the position of the screw element 26 and the lever arm discussed above, as well as the degree of tightening of the screw element 26 and the corresponding reduction in the gap S.
