[0004] Vehicle seat with functional device receptacle and motor vehicle equipped therewith

[0005] The present invention relates to a vehicle seat with at least one functional means receptacle according to claim 1 and to a motor vehicle equipped therewith according to claim 10.

[0006] Vehicle seats are generally known. Depending on the equipment variants, these include functional elements such as lumbar support, fans, heating elements, sensors, etc. Corresponding vehicle seats are known in particular from DE 43 13 813 A1, DE 10 2007 038 294 A1, DE 10 2007 053 119 A1, DE 10 2009 012 963 A1, DE 10 2016 221 507 A1, DE 10 2019 117 764 A1, DE 10 2017205 135 A1, DE 102019 126 174 A1 and DE 102022 120 451 A1. All these vehicle seats have in common that they have a comparatively complex design for the integration of functional elements, which makes manufacturing complex and expensive.

[0007] The object of the present invention is to overcome this disadvantage.

[0008] This problem is solved by a vehicle seat having the features of claim 1.

[0009] Therefore, this task is solved by a vehicle seat comprising a seat surface, a backrest and at least one functional element located in the vehicle seat, characterized by the following features: 23-3362

[0010] 23-3363

[0011] 2

[0012] The seat surface has at least one seat surface frame to which at least one seat surface textile with at least one receptacle for receiving at least one functional element is attached, and / or the backrest has at least one backrest frame to which at least one backrest textile with at least one receptacle for receiving at least one functional element is attached.

[0013] This advantageously allows for the integration of functional elements into vehicle seats without compromising the structural integrity and comfort of the seat fabric. Furthermore, the use of textiles for the seat surface and backrest advantageously enables the relatively simple manufacture of the vehicle seat with specific recesses for functional elements, which can be designed, in particular, as lumbar supports, fans, heating elements, sensors, or the like. Finally, seating comfort can be advantageously adjusted by appropriately positioning, numbering, and designing differently shaped areas of the textile to precisely control the sinking into or contact of the human body with the seat surface or backrest.

[0014] The term "textile" refers to a fabric consisting of at least one or more yarn systems, either a combination of stitches or interlacing of warp and weft threads. Within the scope of this definition, a textile is therefore preferably either a knitted or woven fabric, and particularly preferably a knitted fabric.

[0015] The recesses themselves can be, in particular, pockets integrated into or on the seat fabric and / or the backrest fabric, or recesses between two fabric surfaces. 23-3362

[0016] 23-3363

[0017] 3

[0018] According to a preferred embodiment, the receptacle is formed from at least one recess to which the at least one functional element is connected by frictional, positive, and / or material-locking means. This advantageously improves the design of receptacles for functional elements that are connected to the seat and backrest fabric by frictional, positive, and / or material-locking means.

[0019] According to a preferred embodiment, the receptacle is at least partially pocket-shaped and / or channel-shaped in the seat surface fabric or the backrest fabric. This advantageously provides a space-saving option for accommodating additional elements such as heating wires or sensors. The pocket- or channel-shaped receptacle can serve as a conduit for electrical or mechanical components, which simplifies the manufacturing of the seat components.

[0020] According to a preferred embodiment, the recess, which is at least partially designed as a pocket, is formed using the same textile process as the seat surface textile and / or the backrest textile. This advantageously reduces manufacturing costs and, due to the purity of the materials used, also any recycling costs.

[0021] According to a preferred embodiment, the seat surface fabric and / or the backrest fabric are designed at least partially as a 3D structure. This advantageously improves the structural integrity of the seat and increases the load-bearing capacity and durability of the vehicle seat. 23-3362

[0022] 23-3363

[0023] 4

[0024] According to a preferred embodiment, the seat surface textile has at least one channel-shaped receiving space on its outer edge in which a textile-based seat surface reinforcement profile is at least partially received, and / or the backrest textile has at least one channel-shaped receiving space on its outer edge in which a textile-based backrest reinforcement profile is at least partially received. This advantageously creates effective reinforcement of the textile used, which contributes to increased durability and service life of the seat.

[0025] According to a preferred embodiment, the seat surface reinforcement profile is designed with a rigid seat surface reinforcement profile frame connected to the seat surface frame, and / or the backrest fabric is designed with a rigid backrest reinforcement profile frame connected to the backrest frame. This advantageously increases the structure of the vehicle seat, further improving its stability.

[0026] The seat reinforcement profile frame and / or the backrest reinforcement profile frame can be manufactured in any suitable manner. Preferably, the seat reinforcement profile frame and / or the backrest reinforcement profile frame are injection-molded. Particularly preferably, the seat reinforcement profile frame and / or the backrest reinforcement profile frame are made of the same material as the textile, in particular the seat fabric and / or the backrest fabric.

[0027] According to a preferred embodiment, the seat frame and / or the backrest frame are at least partially made of a technical textile. Advantageously, this allows the 23-3362

[0028] 23-3363

[0029] 5. The structural integrity of the seat is improved, and the load-bearing capacity and durability of the vehicle seat are increased.

[0030] Technical textiles can be made from synthetic fibers, especially polyester (PES), polyamide (PA), polyacrylic (PAN) or polyolefins (polyethylene, polypropylene), or natural fibers, especially cotton, wool or linen.

[0031] According to a preferred embodiment, the technical textile is made with a polyester fiber, preferably a core-sheath fiber. This advantageously represents an environmentally friendly solution that optimizes both the mechanical properties of the vehicle seat and promotes the sustainability of the product.

[0032] The aforementioned problem is also solved by a motor vehicle with at least one vehicle seat of the type disclosed above. The aforementioned advantages apply accordingly.

[0033] The following is a detailed, non-prejudicative, and in particular limiting, description of an embodiment of the present invention with reference to the accompanying figures, which are not to scale. Identical elements are designated with identical reference numerals unless otherwise indicated.

[0034] Fig. 1 is a simplified side view of a vehicle seat according to the invention.

[0035] Fig. 2 is a perspective partial view of the front of the vehicle seat shown in Fig. 1. 23-3362

[0038] Fig. 3 is an enlarged view of part of the vehicle seat shown in Fig. 2.

[0039] Fig. 4 is a perspective partial view of the rear of the vehicle seat shown in Fig. 2.

[0040] Figure 1 shows a motor vehicle 1 symbolically, in which a vehicle seat 5 is mounted in a manner known per se. The vehicle seat 5 comprises, also in a manner known per se, a seat surface 10 and a backrest 15.

[0041] The seat surface 10 has a seat frame 20 to which a seat fabric 25 is attached, with a number of spaced-apart receptacles 30 for receiving functional elements not shown here. The seat surface 10 thus designed is covered by a seat cushion (not shown here) in a manner known per se.

[0042] The backrest 15 has a backrest frame 35 to which at least one backrest fabric 40 is attached, with a number of spaced-apart receptacles 45 for receiving functional elements not shown here. The backrest 15 thus designed is covered by a backrest cushion (not shown here) in a manner known per se.

[0043] The seat frame 20 and the backrest frame 35 are made of a technical textile with a polyester fiber, preferably a core-sheath fiber.

[0044] It should be noted that textile 25, 40 can be made of any suitable material and manufactured in any suitable way. In particular, textile 25, 40 can be designed as a 3D construct. 23-3362

[0047] It should also be noted that the number, structure, and positioning of the receptacles 30 and 45 shown here can differ from those depicted in this figure. In particular, it is possible to provide one, several, or all of the receptacles 30 and 45 on the front and / or back of the seat fabric 25 and / or the backrest fabric 40. The receptacles 30 and 45 can, in particular, be pockets integrated into or on the seat fabric 25 and / or the backrest fabric 40, or recesses between two fabric surfaces.

[0048] Figure 2 shows a partial perspective view of the front of the vehicle seat 5 depicted in Figure 1, more precisely its backrest 15. As can be seen, ten pneumatic cushions 50, serving a massage function, are located on the front of the backrest fabric 40. The four lower functional elements 50 shown in Figure 2 are connected to each other via a common bridge 55 or 60, which in turn are connected to each other by a bridge 65. Each of the first two bridges 55 and 60 is attached to the backrest fabric 40 by a holder 70 or 75, respectively. The two functional elements 50 shown at the top of Figure 2 are also connected to each other by a bridge 80. Like the holders 70 and 75, their holders 85 and 90 are positioned adjacent to the backrest frame 35.However, it is understood that some or all of the functional elements 50 can also be positioned elsewhere and / or freely on the backrest fabric 40.

[0049] As can be seen in Fig. 2, a series of different receptacles 45 are provided on the backrest 15. Thus, a part 95 of the backrest fabric 40 adjacent to the upper section of the backrest frame 35 is formed with a textile whose woven threads have a larger spacing than those of a part 100 of the backrest fabric, not only the fabric 40 that surrounds part 95. Corresponding further parts with increased woven thread spacing are distributed over the surface of the backrest 23-3362

[0050] 23-3363

[0051] 8

[0052] The fabric is not only distributed as fabric 40. Furthermore, there are not only fabric 40 distributed across the surface of the backrest fabric, but also recesses 105, which serve as potential receptacles 45.

[0053] This is further illustrated in Fig. 3, which shows an enlarged view of part of the upper left functional element 50 and its surroundings. The holder 85 comprises a hook element 110 that engages behind an edge region of the receptacle 95. Another exemplary receptacle 45 is channel-shaped and holds a pneumatic line 115 leading to the functional element 50.

[0054] Another receptacle 45 is located on the reverse side of the backrest fabric 40, as can be seen in Fig. 4. The receptacle 45 is designed as a pocket.

[0055] It should be noted that the seat surface textile 25 has a channel-shaped receiving space 45 at its outer edge, in which a textile-based seat surface (not shown here) is received. The backrest textile 40 may have a channel-shaped receiving space 45 at its outer edge, in which a textile-based backrest (not shown here) is received.

[0056] Furthermore, the textile-based seat reinforcement profile may be designed with a rigid textile-based seat reinforcement profile frame that is connected to the seat frame 20. Finally, the backrest textile 40 may be designed with a rigid textile-based backrest reinforcement profile frame that is structurally connected to the backrest frame. 23-3362
