Description

Technical Field

[0001] This invention relates to a vehicle seat having a seat portion and a backrest portion, wherein the backrest portion has a frame element enclosing an inner surface and a knitted fabric arranged on the frame element. Furthermore, this invention relates to the interior design of a vehicle, particularly a passenger vehicle, with a vehicle seat. Background Technology

[0002] Such vehicle seats are used, for example, in passenger transport such as trains. These vehicles are, for example, rail vehicles or airplanes, designed and suited to transport multiple passengers. Corresponding rail vehicles include, for example, local and / or long-distance trains, suburban trains, subway trains, etc. The available space around the seats is typically limited, especially in such vehicles. Therefore, it is necessary to optimize the use of available space as much as possible. A vehicle should be able to accommodate as many passengers as possible. Furthermore, the weight and cost of the vehicle seats play a decisive role, simply because there are a large number of seats in such vehicles, and previous vehicle seats have particularly significant drawbacks. Moreover, the ease and quick replacement of worn parts such as covers is especially important, because intensive use by a large number of passengers, as well as deliberate vandalism, means that covers must be replaced at fixed intervals; therefore, known vehicle seats are typically time- and cost-intensive. Summary of the Invention

[0003] The object of this invention is to provide a vehicle seat that overcomes the aforementioned disadvantages. Furthermore, the object of this invention is to provide an interior decoration for a vehicle that overcomes the aforementioned disadvantages.

[0004] The main concept of the present invention is a vehicle seat having a seat portion and a backrest portion, wherein the backrest portion has a frame element surrounding an inner surface and a knitted fabric arranged on the frame element, the knitted fabric being arranged, at least in a region of the inner surface, to be freely swinging on the front side of the frame element, and a padding support element being arranged in or on the knitted fabric and supported solely by the knitted fabric, at least in a region of the inner surface, the knitted fabric providing sole support and / or padding for the seat user.

[0005] The term “substantially” as used in this article is intended to be understood to include minor tolerance variations with respect to features.

[0006] The frame element includes an inner surface. According to the invention, the inner surface should be understood as a surface without material or empty, which is defined circumferentially by the surrounding frame element.

[0007] According to the invention, knitted fabric represents a seat cover for a backrest, particularly a knitted seat cover. This knitted fabric is advantageously produced using knitting machines. This advantageous use of knitted fabric allows for a high degree of versatility in the design of areas with varying elasticity. This knitted fabric can advantageously combine flexible and rigid or stable sections. Compared to conventional fabrics, knitted fabrics can be produced very simply, cost-effectively, and in a way that is specific to specific applications.

[0008] Knitted fabrics can be produced using certain yarns, wherein preferably the yarn has at least one of the following properties: a maximum tensile strength of up to 60 N, an elongation of up to 20%, and the material is polyester fiber or at least partially made of polyester fiber.

[0009] It is also possible to use different knitted fabrics, which can have different patterns.

[0010] The backrest design of the vehicle seat according to the invention incorporates a frame element and a knitted fabric with padding support elements, ensuring that, at least in the inner surface area, no other elements are required for support and / or padding. In this way, cost, space, and weight are saved compared to conventional vehicle seats. Because it is freely arranged in the inner surface area, the knitted fabric can extend backward into or beyond the inner surface when the seat occupant is loaded, thus providing padding and / or support. Advantageously, the seat cover is designed and intended to withstand the forces exerted by the seat occupant. Therefore, the knitted fabric advantageously possesses corresponding stability. Consequently, no other support or cushioning elements are advantageously provided in the inner surface. Preferably, the knitted fabric can be partially arranged on or above and inside the inner surface area, which is also preferred due to the construction of the padding support elements and the provision of visual and ergonomic advantages.

[0011] Preferably, the vehicle seats described herein are rail seats, i.e. seats for rail vehicles, such as those for intercity and / or long-distance trains, suburban trains, subway trains, etc.

[0012] According to a preferred embodiment, the padding support element is substantially planar. Preferably, the padding support element extends substantially parallel to the inner surface. More preferably, the padding support element has a uniform thickness or a varying thickness. If the padding support element has a uniform thickness, it is particularly easy to construct and position it on or within a knitted fabric. With varying thickness, additional functions can be embossed onto the padding support element, such as structures particularly suitable for the back of the seat user. The thickness of the padding support element refers to the stretch of the padding support element from front to back (i.e., in the installed state, from the seat portion toward the backrest portion and vice versa). Particularly preferably, the padding support element has a protruding lower section that curves forward toward the seat portion and / or a protruding middle section that curves backward. Preferably, the lower section has a uniform thickness across the entire width of the padding support element, decreasing towards the top. And, preferably, the thickness of the middle section decreases outward relative to the width and height. Preferably, the upper section of the padding support element has a uniform thickness. Preferably, the lower section of the padding support element provides support for the lowest lordosis, and the middle section of the padding support element provides support for the upper lordosis. Due to the aforementioned structure of the padding support element, the seat user can achieve a more comfortable sitting posture that is gentler on the back, especially during long journeys.

[0013] According to a preferred embodiment, the padding support element is attached, in particular sewn, to the knitted fabric on the rear side (i.e., the side of the knitted fabric opposite the seat portion), or the knitted fabric is designed as a double-knitted fabric at least in a region of its inner surface and has a closable opening on the rear side, thus providing a pocket element within the knitted fabric. The padding support element can be inserted into the pocket element through the opening in the knitted fabric. Preferably, the pocket element is designed to complement the cushioning support element. Particularly preferably, the pocket element is chosen to be smaller than the padding support element, such that the knitted fabric stretches around the padding support element in the region of the pocket element when the padding support element is inserted. This ensures more secure support and a better appearance. Further preferably, the opening can be reversibly closed by locking elements (particularly threads, hook and loop fasteners, zipper fasteners, or snaps). If the padding support element is attached to the rear side of the knitted fabric, it can be subsequently attached in a particularly simple and material-saving manner. In embodiments with pocket elements, a particularly stable and secure arrangement of the padding support element within the knitted fabric can be achieved, and thus damage to the padding support element can be avoided, for example, when attaching the knitted fabric or removing it from the frame element. The variations of the locking elements mentioned here should not be considered exhaustive, and other variations are conceivable. The decisive factor is the reversible, non-destructive closure or the openness of the opening for inserting or removing the padding support element.

[0014] The preferred embodiments of the padding support element and the knitted fabric described above make the padding support element particularly easy to adapt to a given seat size and required functionality, whereby the elasticity of the knitted fabric means that the adaptability of the padding support element does not require any changes to the knitted fabric.

[0015] According to a preferred embodiment, the frame element has at least one fastening element on each of at least two opposing inner sides, and the knitted fabric has a complementary fastening element formed and arranged on the rear side. Preferably, the knitted fabric is secured to the frame element by the fastening elements such that, starting from the front side of the frame element facing the seat portion, the knitted fabric at least partially surrounds the frame element from the outside to the inside and is substantially fully taut.

[0016] The complementary arrangement of the fastening elements of the frame element and the knitted fabric should be understood as an arrangement that enables a permanent, particularly detachable, rigid (positive) connection between the frame element and the knitted fabric through the fastening elements. Furthermore, the complementary arrangement should be understood to mean, in addition to connectivity, the spatial arrangement of the fastening elements on the frame element and the knitted fabric, thereby allowing the fastening elements to achieve a corresponding connection with the intended fit of the knitted fabric on the frame element. Therefore, the number of fastening elements on the frame element and the knitted fabric is preferably the same, with each fastening element on the frame element having a complementary shape and spatial layout, and vice versa.

[0017] According to a preferred embodiment, the frame element includes a continuous upper region for supporting the head and a lower region having an inner surface for supporting the back. The upper region is therefore continuous, i.e., not made of material, in contrast to the inner surface, where foam elements can be disposed for additional head padding. Preferably, one inner side of the upper region defines the inner surface from above, and three inner sides of the lower region define the inner surface from the sides and below. More preferably, the frame element has at least one fastening element on each inner side defining the inner surface. Due to the fastening elements, the knitted fabric is advantageously tensioned and arranged on the frame element. Preferably, the fastening elements on the frame element and the knitted fabric are designed such that the fixation of the knitted fabric to the frame element is releasable without causing damage. Particularly preferably, the fixation between the frame element and the knitted fabric is a releasable rigid connection.

[0018] Preferably, the fastening elements on the frame element are in the form of hooks, straps, Velcro fasteners, zipper fasteners, or snaps. Preferably, several different types of fastening elements or only one type of fastening element are provided. The fastening elements are not intended to be limited to the types mentioned herein. Preferably, one or more types of fastening elements are selected according to the corresponding application. Advantageously, all types of fastening elements share the common feature of ensuring a releasable rigid connection. More preferably, some fastening elements or a continuous fastening element are distributed along the length of the inner side of the frame element. In this way, particularly stable fixation and tensionability of the knitted fabric are ensured.

[0019] According to a preferred embodiment, the knitted fabric includes a tubular upper section having two open sides. This tubular knitted fabric can be viewed as a relatively flat structure joined together at its two outer boundaries. Advantageously, this knitted fabric is manufactured using a 3D knitting process. Preferably, the first open side is closed. Simply put, the upper section thus has a sock-like shape and is easy to slip on. More preferably, the tubular upper section of the knitted fabric is arranged to surround the upper region of the frame element. This design and arrangement of the upper section ensures that the knitted fabric is easily positioned onto the frame element before being secured by fastening elements. Preferably, the knitted fabric has a lower section that is substantially flat and directly adjacent to the upper section in front. Particularly preferably, the lower section contacts the lower region of the frame element from the front and, starting from the front side of the frame element, at least partially surrounds the lower region from the outside inwards. Preferably, the lower section is formed as a plain knitted fabric. A plain knitted fabric is a substantially flat structure surrounded by an outer boundary. This flat structure can be of any shape, such as a polygon. If the thickness of the plain knit fabric is ignored, it can be considered as a substantially two-dimensional, flat structure. In this way, the lower section can easily adapt to the shape of the lower area of ​​the frame element, thereby enabling the knit fabric to be attached to the frame element at least partially surrounding or around it.

[0020] According to a preferred embodiment, complementary fastening elements of the knitted fabric are arranged at the rear boundary of the open second opening side of the upper section and at the side and bottom boundary sides of the lower section. By arranging the fastening elements on the knitted fabric, the fabric can be secured to the fastening elements on all the inner sides of the defining inner surface of the frame element. Preferably, the fastening elements in the upper section are designed to be arranged continuously along the length of the open second opening side. Preferably, the fastening elements in the lower section are designed as a plurality of fastening elements arranged at the edges along the length of the left, right, and bottom sides.

[0021] According to a preferred embodiment, a padded support element is disposed on or in the lower section of the knitted fabric, protruding forward in the direction of the seat portion, at least in a region of the inner surface, thereby forming a forward-protruding area that provides the appearance of an attached padding from the front. Due to this arrangement, the back of the seat user first comes into contact with the padded support element disposed in or on the knitted fabric, thereby ensuring optimal padding and support.

[0022] According to a preferred embodiment, at least two, preferably at least four, and more preferably six fastening units are fixedly arranged on the knitted fabric. Preferably, the fastening unit has fastening elements arranged on the knitted fabric, and each fastening unit includes at least one fastening element. Preferably, the fastening unit is fixed, particularly sewn to the boundary side of the knitted fabric, especially oppositely, and formed in a strip-like manner. More preferably, the fastening elements arranged on the fastening unit protrude beyond the bottom surface of the knitted fabric. Preferably, the fastening unit is made of a different material from the knitted fabric, particularly a rigid, tear-resistant material. In this way, the fastening unit on the knitted fabric is inelastic and provides firm support for the complementary fastening elements formed on the frame element. Further advantageously, by subsequently attaching the fastening unit and then the fastening element, the position and type of each fastening element can be adapted to the existing condition or design of the frame element.

[0023] The aforementioned objective is also achieved by the interior decoration of a means of transport, particularly a passenger vehicle, which includes at least one vehicle seat. This vehicle seat can possess, individually or in combination with each other, all the features already described above, and vice versa. Attached Figure Description

[0027] Figure 1 A perspective view of the interior decoration of a means of transport (in this case, a train or railway) is shown, in the form of a double-track seat comprising two vehicle seats according to the invention, which may have the essential features of this application. This interior decoration 100 essentially comprises two vehicle seats 1 arranged side-by-side, each vehicle seat including a seat portion 2, a backrest portion 3, an armrest 8, a headrest 9, and a cantilevered seat base 10.

[0028] Figure 2 The backrest portion 3 of the vehicle seat 1 according to the present invention is shown in an exploded view.

[0029] The backrest portion 3 includes a frame element 4 and a knitted fabric 5 detachably attached thereto, particularly in a form-fitting manner, or attached thereto.

[0030] The frame element 4 has an upper region 11 and a lower region 12 connected thereto. The upper region 11 and the lower region 12 together enclose an inner surface 13, which is exposed, i.e., no other elements are disposed there on the frame element 4. The inner surface 13 is substantially rectangular.

[0031] The upper region 11 has an upper side 14a with two rounded corners and a transverse member 14b with an inner side 14c, the transverse member 14b or the inner side 14c closing the upper region 11 downward toward the inner surface 13. The upper region 11 also includes a headrest fastener 44 to which the headrest 9 can be secured.

[0032] Preferably, the headrest 9 is fixed to the frame element 4 by screws, such that the headrest fastener 44 has corresponding threads. A generally rectangular foam insert 19 is arranged between the headrest attachment 44 and the cross member 14b, serving as padding or support for the shoulders.

[0033] The lower region 12 includes a first side support 15 having an inner surface 15a facing the inner surface 13, an outer surface 15b facing the inner surface, a front surface 15c facing the seat portion 2, and a rear surface 15d. The lower region 12 also includes a second side support 16 having an inner surface 16a facing the inner surface 13, an outer surface 16b facing the inner surface, a front surface 16c facing the seat portion 2, and a rear surface 16d. The lower region 12 further includes a transverse member 17 having an inner surface 17a or upper surface 17b facing the inner surface 13, an outer surface 17b or lower surface 17b facing the inner surface, a front surface 17c facing the seat portion 2, and a rear surface 17d.

[0034] Several hook-shaped fastening elements 41 are formed along the length of the inner side 15a, extending into the inner surface 13. Several hook-shaped fastening elements 42 are formed along the length of the inner side 16a, extending into the inner surface 13. Several hook-shaped fastening elements 43 are formed along the length of the inner side 17a, extending into the inner surface 13.

[0035] On the outer side 17b or lower side 17b, in each case, laterally (left and right) arranged seat leg connecting elements 30a, 30b for connecting to the seat leg 10 and seat portion connecting elements 31a, 31b for connecting to the seat portion 2. The side pillars 15, 16 each have connecting axes 40a, 40b, thus the side pillars 15, 16 can be considered as two parts. This has the advantage that the connected seat portion 2 can be pushed back and forth, so that only the lower part of the side pillars 15, 16 in the lower region 12 moves upward to the connecting axes 40a, 40b. Furthermore, a support pillar 18 is provided, connected to the rear sides 15d, 16d of the side pillars 15, 16 and located behind the inner surface 13. The support pillar 18 has a stabilizing effect.

[0036] The knitted fabric 5 has an upper section 20 and a lower section 21. The upper section 20 is tubular, having a closed upper opening side 20a and an open lower opening side 20b. When closed, the upper section 20 slides over the upper region 11 of the frame element 4. The upper section 20 also includes a headrest recess 29 with a circular recess 33. The headrest 9 is disposed in the region of the headrest recess 29, whereby the recess 33 is intended for the passage of screws that secure the headrest in the headrest fastener 44 of the upper section 11.

[0037] The lower section 21 is substantially planar and directly connects to the second opening side 20b of the upper section 20 at the front. In the attached state, the lower section 21 contacts the lower region 12 of the frame element 4 from the front. Starting from the front side of the frame element 4, the lower section 21 at least partially surrounds or crosses the lower region 12 from the outside inward.

[0038] Furthermore, in the lower section 21, the knitted fabric 5 is formed as a double-layered knitted fabric at least in the area of ​​the inner surface 13 and has a closable opening 34 on the rear side, such that the knitted fabric 5 has a pocket element 45 into which a padding support element 32 can be inserted via the opening 34 in the knitted fabric 5. The pocket element 45 is formed to complement the padding support element 32. The padding support element 32 is arranged in the area of ​​the inner surface 13 and is substantially planar and extends substantially parallel to the inner surface 13. The knitted fabric 5 and the padding support element 32 provide the seat user's back with sole padding and / or support in the area of ​​the inner surface 13, without the need or necessity for other elements to be placed there.

[0039] On the rear side of the knitted fabric 5, there is an upper fastening unit 22 having a continuous fastening element 22a along its entire length, a first lateral fastening unit 23 having a plurality of fastening elements 23a distributed along its length, a second lateral fastening unit 24 having a plurality of fastening elements 24a distributed along its length, a third lateral fastening unit 25 having a plurality of fastening elements 25a distributed along its length, a fourth lateral fastening unit 26 having a plurality of fastening elements 26a distributed along its length, and a lower fastening unit 27 having a plurality of fastening elements 27a distributed along its length. The specific positions of the fastening units 22, 23, 24, 25, 26, and 27 on the rear side of the knitted fabric are as follows (see reference below). Figure 3b As shown. Fastening elements 23a, 24a, 25a, 26a, and 27a are formed as groove-shaped recesses complementary to hook-shaped fastening elements 41, 42, and 43, thereby ensuring a releasable rigid (positively) connection. Fastening element 22a is strip-shaped and therefore can interact with the transverse member 14b or the inner side 14c of the transverse member 14b to form a releasable rigid connection. Thus, the transverse member 14b and the inner side 14c are themselves formed as fastening elements, or fastening elements 14b and 14c that may be referred to as frame element 4, and the frame element 4 therefore also has this fastening element on the inner side 14c. Lateral fastening units 23, 24, 25, and 26 are further divided to the left and right sides, respectively, i.e., into fastening units 23 and 25 and 24 and 26. Since the side supports 15 and 16 of the frame element 4 are also divided by connecting axes 40a and 40b, rotational flexibility and stable fixation about the axes are ensured.

[0040] In addition, a locking element 28 is shown, which is configured to releasably close the knitted fabric 5 in a force-operated manner (not shown here; see also...). Figure 3b Opening 34 in ).

[0041] Figure 3a A front view of the backrest portion 3 is shown. Here, the knitted fabric 5, having an upper section 20 and a lower section 21, is visible, including a padding support element 32 arranged in an inner pocket element 45 of the knitted fabric 5. In the lower section 21 of the knitted fabric 5 where the padding support element 32 is arranged, a forward-protruding region 49 is formed at least in the inner surface region 13, which curves forward toward the seat portion 2 and protrudes forward beyond the lower region 12 of the frame element 4, creating a cushion-like appearance, giving it the appearance of a front-placed cushion. In the upper section 20, four recesses 33 are arranged in a square or rectangular pattern. Furthermore, seat base connecting elements 30a, 30b arranged laterally on the outer side 17b or lower side 17b for connecting the seat base 10, and seat portion connecting elements 31a, 31b for connecting the seat portion 2, are visible. The knitted fabric 5 is configured such that the seat leg connecting elements 30a, 30b are each covered by the knitted fabric 5 or stretched around it on the outside.

[0042] Figure 3b A rear view of the backrest portion 3 is shown. Here, the tubular upper section 20 of the knitted fabric slides over the upper region 11 of the frame element 4, and the fastening elements 22a, 23a, 24a, 25a, 26a, and 27a on the fastening units 22, 23, 24, 25, 26, and 27 of the knitted fabric are connected to complementary fastening elements 14b, 14c, 41, 42, and 43. The fastening units 22, 23, 24, 25, 26, and 27 are each attached to, and in particular sewn to, the boundary side of the knitted fabric 5. The upper fastening unit 22 is provided at the upper boundary region 36 formed at the second opening side 20b, and thus can be used as a fastening element to connect the cross member 14b or the inner side 14c of the cross member 14b. The first lateral fastening unit 23 and the third lateral fastening unit 25 are arranged at the second lateral boundary region 38 of the knitted fabric 5. The second lateral fastening unit 24 and the fourth lateral fastening unit 26 are arranged at the first side boundary region 37 of the knitted fabric 5. The lower fastening unit 27 is arranged at the lower boundary region 39 of the knitted fabric 5. In the attached state, the side boundary regions 37, 38 of the knitted fabric 5 are arranged such that they surround or cross the side supports 15, 16 of the frame element 4 from the front, starting from the front side 15c, 16c, passing through the outer side 15b, 16b and the rear side 15d, 16d to the fastening elements 41, 42 on the inner side 15a, 16a. In the attached state, the lower boundary region 39 of the frame element 5 is arranged such that it surrounds the transverse member 17 of the frame element 4 from the front, starting from the front side 17c, passing through the outer or lower side 17b and the rear side 17d to the fastening element 43 on the inner or top side 17a.

[0043] Mounting strips 35a and 35b are arranged on each side support 15 and 16 above the knitted fabric 5 or above the side boundary areas 37 and 38, and are preferably screwed to the rear sides 15d and 16d. Mounting strips 35a and 35b are used to secure the backrest portion 3. Supporting pillars 18 are also connected to the ends of the side supports 15 and 16 above the knitted fabric 5 or the side boundary areas 37 and 38, and are preferably screwed to the rear sides 15d and 16d.

[0044] In the lower section 21 of the knitted fabric 5, a rearwardly curved region 50 is formed in the region of the inner surface 13, away from the seat portion 2. The rearwardly curved region 50 is located in the region of the support column 18, such that when the knitted fabric 5 loads the seat user and the knitted fabric 5 thus generates a rearward stretch, the rearwardly curved region 50 contacts the support column 18, thereby ensuring further support for the upper lordosis.

[0045] Furthermore, the back side of the knitted fabric 5 shows an opening 34 in the form of a horizontal groove through which the padding support element 32 can be inserted into a pocket element 45 in the lower section 21 of the knitted fabric 5, where the knitted fabric 5 is at least partially double-layered. The opening 34 is releasably and rigidly closed by a cord-like locking element 28, so that the padding support element 32 cannot accidentally come out of the pocket element 45.

[0046] Figure 3b Three cutting axes S1, S2, and S3 are also shown, indicating that through such... Figures 4a-4c The backrest section shown is cut into 3.

[0047] Figure 3c It shows that according to Figure 3a and 3b A side view of the backrest portion 3 of the embodiment. In this figure, the forward-convex region 49 and the rear-convex region 50 can be seen.

[0048] Figure 4a , 4b 4c each shows along according to Figure 3b A cross-sectional view of the back part 3 of the cutting axes S1, S2, and S3.

[0049] Figure 4aThe diagram shows a cross-sectional view along the cutting axis S1, whereby the backrest portion 3 or the knitted fabric 5 is shown as an embodiment formed as a single layer without the padding support element 32. It can be seen how the knitted fabric 5 or its side boundary regions 37, 38 surround or cross the side supports 15, 16 of the frame element 4 from the front, starting from the front 15c, 16c, via the outer 15b, 16b and the rear 15d, 16d to the fastening elements 41, 42 on the inner 15a, 16a. The lower boundary region 39 is arranged in a manner similar to the side boundary regions 37, 38. Essentially, the knitted fabric 5 or each boundary region 37, 38, 39 is deflected by 90°. The knitted fabric 5 is arranged to swing freely in the region of the inner surface 13. In the cross-section shown, the knitted fabric 5 extends on or beyond the inner surface 13.

[0050] Side supports 15 and 16 have recesses. This allows for the use of less material, thus reducing weight. The front side 15c of the first side support 15 slopes downward from the inner side 15a to the outer side 15b, meaning the inner side 15a is longer than the outer side 15b. The front side 16c of the second side support 16 starts from the outer side 16b and slopes downward towards the inner side 16a, meaning the outer side 16b is longer than the inner side 16a.

[0051] exist Figure 4b The image shows a cross section along the cutting axis S2, whereby the backrest portion 3 or the knitted fabric 5 is shown as an embodiment with a padded support element 32 and a double-layer design, at least in the area of ​​the inner surface 13.

[0052] In the region of the inner surface 13, a padding support element 32 can be seen within a double-layered knitted fabric 5 that forms a forward-curving region 49 that curves towards the seat portion 2 and protrudes beyond the frame element 4. In this cross-section shown, the knitted fabric 5 extends on or beyond the inner surface 13.

[0053] Figure 4b The other embodiments shown correspond to the above with the necessary modifications. Figure 4a The features described in the text.

[0054] Figure 4c The image shows a cross section along the cutting axis S3, whereby the backrest portion 3 or the knitted fabric 5 is shown as an embodiment with a padded support element 32 and a double-layer design, at least in the area of ​​the inner surface 13.
