Description

Technical Field

[0001] The present invention relates to a seat, in particular a vehicle seat, comprising a seat cushion element and a backrest element, wherein the backrest element is connected to the seat cushion element, wherein at least one surface element is arranged on or in the surface of the backrest element, wherein the surface element comprises a first mirror / reflector, a second mirror and a frame, wherein the mirror surface / reflective surface of the first mirror is oriented toward the second mirror and the mirror surface of the second mirror is oriented toward the first mirror. The surface element further comprises at least one depth effect element, which is arranged between the first mirror and the second mirror so that the at least one depth effect element is visible to an observer at least through the second mirror. The present invention also relates to the use of the surface element for visually simulating an opening in the backrest element of a seat. Background Art

[0002] A seat typically includes a seat cushion element designed to accommodate the seat's buttocks. Furthermore, most seats include a backrest element, against which the seated person can lean their back. To ensure comfortable back support and good back support, the backrest element may be dimensioned so that it is longer and wider than the seated person's upper body. Backrest elements dimensioned in this way often appear very thick and can obstruct the seated person's view backward. Therefore, through-holes or openings are often provided in the seat's backrest element to give the entire seat a slender and lightweight appearance. Furthermore, these openings allow for unobstructed viewing behind the seat. A disadvantage of such through-holes in the seat backrest is that the seat cover applied to the backrest element must be adapted to the through-holes. This makes the shape and manufacture of such a seat cover complex. Furthermore, through-holes in the backrest element weaken the seat's strength, which must be compensated for by additional components within the seat.

[0003] DE 10 2005 027 074 A1 describes a vehicle seat having a plurality of through-holes in a backrest element. These through-holes are used, on the one hand, as openings for threading seat belts and, on the other hand, for arranging a handle for unlocking the backrest element.

[0004] WO 2021 / 034866 A1 describes a component for a vehicle interior that is constructed from multiple layers and includes a light source within it. At least one layer of the component is transparent. The interaction of the light source with the various layers of the component creates an attractive visual effect for the vehicle interior. Summary of the Invention

[0005] The object of the present invention is to provide a seat which is of simple and stable construction and which at the same time has an attractive and lightweight appearance.

[0006] The object of the present invention is achieved by a seat, in particular a vehicle seat, which comprises a seat cushion element and a backrest element, wherein the backrest element is connected to the seat cushion element, wherein at least one surface element is arranged on or in the surface of the backrest element, wherein the surface element comprises a first mirror, a second mirror and a frame, wherein the frame connects the first mirror to the second mirror, and a gap is provided between the first mirror and the second mirror, wherein the mirror surface of the first mirror is oriented toward the second mirror, and the mirror surface of the second mirror is oriented toward the first mirror, wherein the mirror surface of the second mirror is designed to be translucent or the mirror surface of the second mirror and the mirror surface of the first mirror are both designed to be translucent, wherein the surface element comprises at least one depth effect element, which is arranged between the first mirror and the second mirror, so that the at least one depth effect element can be seen by an observer at least through the second mirror, and the surface element comprises at least one mounting element, which is connected to the first mirror, the second mirror and / or the frame, wherein the mounting element is also connected to the surface of the backrest element or to an element inside the backrest element.

[0007] The seat according to the invention is suitable for use in vehicles, such as cars. Alternatively, however, the seat can also be used in other applications, such as in restaurants, cinemas or clinics. The seat comprises a seat cushion element on which a person can sit. In addition, the seat comprises a backrest element, which is connected to the seat cushion element. The backrest element is used to support the back of a person sitting on the seat cushion element. It is preferably designed so that the relative position of the backrest element with respect to the seat cushion element can be adjusted. The seat according to the invention comprises at least one surface element, which is arranged on or in the surface of the backrest element. The surface element is provided to visually create the impression of an opening or a through-hole in the backrest element, while in reality no such opening or such through-hole exists in the backrest element.

[0008] The surface element is constructed in multiple layers and has a smaller thickness compared to its length and width. Thus, for example, the length and width of the surface element can be at least five times greater than its thickness. This allows the surface element to be placed on or within the backrest element without significantly occupying the structural space within the backrest element. This allows the interior of the backrest element to be used for arranging other seat components, such as a stable seat support structure. The surface element comprises a first mirror and a second mirror, which are connected to each other via a frame. A frame is understood here to mean a component that secures the two mirrors to each other, i.e., provides a gap between the two mirrors. The frame can completely surround the two mirrors. Alternatively, however, the frame can be formed by one or more separate fixing elements that connect the two mirrors and secure them in their relative position. Each of the two mirrors has a mirror surface, wherein the mirror surface is oriented toward the other mirror arranged oppositely. At least the mirror surface of the second mirror is designed to be translucent. Translucent means that the mirror surface reflects a portion of the light incident on it, while allowing another portion of the light incident on it to pass through the mirror surface and the mirror. A translucent mirror surface can, for example, reflect 50% of incident light and allow 50% to pass through the mirror. The mirror can include components made of glass or organic glass. At least one depth effect element is arranged in the gap between the first and second mirrors, and can be perceived by an observer at least through the second mirror, which in this case has a translucent mirror surface. The two mirrors are arranged opposite each other, and at least one of the mirror surfaces is translucent, allowing the depth effect element to be repeatedly and continuously visible to an observer viewing the surface element. This device can also be referred to as an infinity mirror, as it creates the impression that the depth effect element is visible infinitely far into the surface element. The visual effect created by the surface element is physically based on the multiple reflections of light back and forth between the two mirrors, with a portion of the light being able to pass through the translucent mirror surface and into the observer's eye. This creates the impression for the observer of an opening or tube extending into the surface element and, therefore, into the backrest element. The surface element thus simulates the visual impression of an opening or through-hole in the backrest element, without any actual opening in the backrest element.

[0009] The surface element further comprises at least one mounting element, which can be designed differently. Possible embodiments of such a mounting element are described further below. The mounting element serves to connect the surface element to the backrest element of the seat in a simple manner.

[0010] The advantage of the seat according to the present invention is that it has an elegant and lightweight appearance, achieved by visually simulating one or more openings or through-holes in the backrest element. However, in reality, no openings or through-holes exist in the backrest element. This allows the backrest element to be constructed simply and stably. In particular, a seat cover, which is simple to construct and cost-effective to manufacture, can be applied to the backrest element. The seat cover forms the surface of the backrest element. Furthermore, the interior of the backrest element can be fully utilized for arranging the seat support structure, seat cushions, or other components important to the seat's function. The arrangement of these components is not disrupted by the openings or through-holes. Another advantage is that the appearance of the surface elements can be easily adapted or modified. In particular, the appearance of the surface elements can be modified by designing and modifying the depth effect elements. For example, the depth effect elements can be designed to be self-luminous, with their color electronically adjustable. In this way, the seat's appearance can be tailored to individual preferences. The seat's simple design also reduces weight compared to seats with actual openings or through-holes in the backrest element.

[0011] In one embodiment, the first and second mirrors of the surface element are oriented parallel to each other, and / or the depth effect element is designed to be self-luminous, and / or the depth effect element is connected to the frame, in particular, the depth effect element is designed as a self-luminous strip that at least partially surrounds the gap between the first and second mirrors in the circumferential direction around the normal on the second mirror. In this embodiment, the two mirrors, in particular their mirror surfaces, are oriented parallel to each other. As a result, an observer looking at or in the surface element sees an opening that extends straight and infinitely. Alternatively, the two mirrors can be oriented at an angle of a few degrees, for example 3°, to each other. In this way, a visual effect that simulates a curved opening is formed. The depth effect element is preferably designed to be self-luminous and include one or more light-emitting devices. The visual simulation of the opening works particularly well with the self-luminous depth effect element, and the observer can see a simulated opening that extends into the surface element over a large virtual length. Alternatively, the depth effect element can be designed to be non-luminous but reflective. In this alternative embodiment, light penetrates the second mirror into the surface element and is reflected by the depth effect element. However, depending on the light intensity outside the surface element, only a small amount of light reaches the depth effect element in this alternative embodiment, resulting in a visually simulated depth that is less pronounced than with an illuminated depth effect element. Self-luminous depth effect elements can be controlled in various ways, with a control unit provided for this purpose. For example, the depth effect element's illumination intensity or color can be adjusted by the user. If the seat is formed by a vehicle seat in a vehicle, the control unit for the depth effect element's illumination can be integrated with the vehicle's control unit. For example, the control unit can be designed so that it automatically activates the depth effect element's illumination when the vehicle's doors are opened or unlocked. Furthermore, provision can be made for the depth effect element's illumination to be automatically deactivated when the vehicle is exited. Furthermore, provision can be made for the illumination color to be adjustable via a control menu on the vehicle's central control unit. Furthermore, the depth effect element's illumination can be linked to the vehicle's set driving mode. Thus, for example, the illumination color in the vehicle's sport mode can be different from the driving mode set in rainy conditions. A particularly strong effect is achieved when the depth effect element is designed as a self-luminous strip that extends around both mirrors in the gap between them. Here, the depth effect element itself is designed to be closed. In this embodiment, the surface element produces an effect in which the simulation of an opening is particularly clear, because the depth effect element reproduces the shape of the second mirror that can be seen from the outside.

[0012] In another embodiment, the mounting element is designed as a bracket that is at least partially rigid and fixedly connected to the first mirror and / or the frame, wherein the mounting element is fixedly connected to an element inside the backrest element, in particular to the seat support structure. In this embodiment, the mounting element connects the surface element to an element or component inside the backrest element. The fixing and positioning of the surface element is thus rigid. To this end, the mounting element is designed as a rigid bracket, which can be formed, for example, by a tube, a rod, etc. If the seat has a seat cover, the mounting element designed as a bracket passes through the seat cover.

[0013] In an alternative embodiment, the mounting element is designed as a connecting element, which is connected to the first mirror, the second mirror or the frame and at least partially surrounds a surface element in a circumferential direction around a normal to the second mirror, wherein the mounting element is connected to the seat cover of the backrest element, in particular, wherein the surface element is not connected to elements inside the backrest element. Here, a connecting element should be understood to be an element that is suitable for connecting to a seat cover that forms the surface of the backrest element. The connecting element can, for example, be designed as a circumferential flange into which the adjacent edge of the seat cover can be clamped. Alternatively, the connecting element can also be designed as a foil or fabric strip that is adhesively bonded or sewn to the adjacent edge of the seat cover. In this embodiment, the surface element is only connected to the seat cover, but not to elements inside the backrest element. In this way, the surface element is supported in a floating manner on or in the surface of the backrest element. The advantage of this embodiment is that the surface element can be easily removed or replaced together with the seat cover. Furthermore, in this embodiment, since the surface element is not rigid but movably connected to the rest of the seat, the risk of injury to the person sitting on the seat is very low. If the seat is installed in a vehicle, for example, this embodiment can reduce the risk of injury to the person sitting on the seat in the event of an accident. In this embodiment, it is particularly preferred that the surface element is also constructed from elastic components. Thus, the two mirrors can be made of polycarbonate or polymethyl methacrylate, for example. These materials are at least partially elastic and have better, more reliable fracture and fragmentation properties than conventional materials, such as glass.

[0014] In another embodiment, the surface element is arranged on or in the half of the backrest element facing away from the seat cushion element, wherein the second mirror of the surface element faces the seat cushion element or faces away from the seat cushion element. In this embodiment, the surface element is arranged in or on the upper half of the backrest element. In this way, the surface element can be clearly seen and realizes the visually light appearance of the chair. Here, the second mirror can face forward toward the seat cushion element or face away from the seat cushion element.

[0015] In one embodiment, it is provided that the position and / or orientation of the backrest element can be adjusted relative to the seat cushion element, wherein the surface element moves together with the backrest element when the position and / or orientation of the backrest element is adjusted. In this embodiment, the backrest element can be adjusted relative to the seat cushion element. It is preferably designed here so that at least the angle occupied by the backrest element relative to the seat cushion element can be adjusted. By arranging the surface element on the backrest element, the surface element moves together with the backrest element when the backrest element is adjusted. Alternatively, of course, the backrest element of the seat is not adjustable and the seat can be integrated into a bench seat, for example. Such a rigid embodiment of the seat can be integrated into a rear bench seat of a vehicle, for example, or installed in a train.

[0016] In another embodiment, the backrest element comprises a headrest and a backrest, wherein the backrest is connected to the seat cushion element and the headrest is arranged on the side of the backrest facing away from the seat cushion element. The surface element is arranged on or in the surface of the headrest or on or in the surface between the backrest and the headrest. In this embodiment, the backrest element has two functional sections: the backrest, which is provided to support the back of a person sitting in the seat, and the headrest, which is provided to support the person's head. The backrest and the headrest can be formed by different interconnected components. Alternatively, however, the backrest element can be designed as a single piece, with the backrest and the headrest forming sections of a single component. In the second embodiment, the surface element can be particularly advantageous for visually enhancing the seat design. If the surface element is arranged on or in the surface of the headrest or on or in the surface between the backrest and the headrest, it creates the visual impression that the headrest and the backrest are separate. In this case, however, a single-piece backrest element is actually provided, which is particularly stable and simple to construct. In this embodiment, the surface element thus achieves a particularly light and elegant appearance of the seat, while at the same time the seat is very sturdy and ensures a high level of safety for the person sitting on it. This is particularly advantageous when the seat is designed as a vehicle seat, since it contributes to the active and passive protection of the person in the event of a vehicle accident.

[0017] In another embodiment, the backrest element is designed to be closed in the area in which the surface element is arranged, in particular, the seat foam material, the seat support structure, or the functional elements of the seat are arranged at least partially below the surface of the backrest element on which or in which the surface element is arranged. Preferably, the backrest element itself is designed to be closed below the surface element and has no actual opening. This provides a particularly stable backrest element. Alternatively, however, the surface element can also be arranged in the actual opening to achieve a special appearance of the seat.

[0018] In another embodiment, it is provided that two or more surface elements are arranged on or in the surface of the backrest element, wherein at least two surface elements are arranged side by side in or on the surface of the backrest element, and the second mirror is oriented in the same direction, or at least two surface elements are arranged opposite each other on or in the surfaces of the backrest element, and the second mirror is oriented in opposite directions. Two or more surface elements can also be arranged on the seat. Here, the surface elements can be positioned and oriented in different ways. Thus, for example, multiple surface elements can be arranged on or in the surface facing the seat cushion element. Alternatively or additionally, other surface elements can be arranged in or on the surface facing away from the seat cushion element. The dimensions of these surface elements can be the same or different.

[0019] Furthermore, the object of the present invention is achieved by the use of a surface element for visually simulating an opening in a backrest element of a seat, in particular a vehicle seat, wherein the surface element comprises a first mirror, a second mirror and a frame, wherein the frame connects the first mirror to the second mirror, a gap is provided between the first mirror and the second mirror, wherein the mirror surface of the first mirror is oriented toward the second mirror and the mirror surface of the second mirror is oriented toward the first mirror, wherein the mirror surface of the second mirror is designed to be translucent or the mirror surface of the second mirror and the mirror surface of the first mirror are both designed to be translucent, wherein the surface element comprises at least one depth effect element, which is arranged between the first mirror and the second mirror so that the at least one depth effect element can be seen by an observer at least through the second mirror.

[0020] By using the described surface elements to visually simulate an opening in a seat, a seat can be provided that is both robustly constructed and attractively designed. The use of surface elements can give a seat with a continuous, stable backrest element a visually lighter and more sporty appearance. However, the seat retains its robust structure and can be manufactured cost-effectively.

[0021] Features, functions and advantages disclosed in relation to the seat are also considered disclosed in relation to the use. Conversely, features, functions and advantages disclosed in relation to the use are also considered disclosed in relation to the seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Figure 1 The seat 100 according to the present invention is shown. Figure 2 ) is a schematic side cross-sectional view of a surface element 1 of an embodiment of the present invention. Figure 1Surface element 1 is shown without the remaining components or parts of seat 100. Surface element 1 comprises a first mirror 11, shown on the left, and a second mirror 12, shown on the right, spaced apart therefrom. In the illustrated embodiment, first mirror 11 and second mirror 12 are oriented parallel to each other. A gap exists between first mirror 11 and second mirror 12. First mirror 11 and second mirror 12 each have a mirror surface, with the mirror surface of first mirror 11 oriented toward second mirror 12, and the mirror surface of second mirror 12 oriented toward first mirror 11. The supporting structure of mirrors 11 and 12 can be formed, for example, by a glass plate or a plexiglass plate. The mirror surface can be formed, for example, by a reflective coating applied to the supporting structure of mirrors 11 and 12. This reflective coating can be formed, for example, by a metal oxide layer. In the illustrated embodiment, the mirror surface of first mirror 11 is opaque and therefore 100% reflective. In contrast, the coating of second mirror 12 is designed to be translucent and only 50% reflective. This means that a portion of the light incident on the mirror surface of the second mirror 12 from the left is reflected by the translucent mirror surface, while another portion of the light passes through the second mirror 12 to the right. The two mirrors 11 and 12 are connected and positioned relative to each other by a frame 13. In the illustrated embodiment, the frame 13 surrounds the two mirrors 11 and 12, which are oriented parallel to each other, circumferentially around the normal to the second mirror 12. Because the frame 13 completely surrounds the two mirrors 11 and 12, the gap between the two mirrors 11 and 12 is protected from dirt and environmental influences and sealed from the exterior of the surface element 1. The surface element 1 also includes a depth effect element 14, which is arranged in the gap between the first mirror 11 and the second mirror 12. If an observer looks through the second mirror 12 from the right, the depth effect element 14 is visible. In the illustrated embodiment, the depth effect element 14 is designed as a self-luminous strip that completely surrounds the gap between the first mirror 11 and the second mirror 12 along the frame 13 and circumferentially around the normal to the second mirror 12. The self-luminous strip can, for example, include multiple LEDs or other light-emitting devices. The depth effect element 14 can be controlled electronically with respect to its luminous effect. For example, it can be provided that the depth effect element 14 is actuated in such a way that it changes its color or luminous intensity according to the user's wishes. In the embodiment shown, the surface element 1 comprises two differently designed mounting elements 15. Usually, a single mounting element 15 is sufficient for mounting the surface element 1 on other components of the seat 100. Figure 1Two differently designed mounting elements 15 are shown in the figure to illustrate their shape and function. A mounting element 15 designed as a rigid bracket can be seen to the left on the first mirror 11. This mounting element 15 can be formed, for example, by a rod or a tube, which is fixedly connected to the first mirror 11 on one side. The end of the mounting element 15 opposite the connection to the first mirror 11 can be fixed, for example, to the backrest element 102 ( Figure 2 ) on the internal load-bearing structure, for example by screw connection. The second mounting element 15 is shown around the frame 13. The second mounting element 15 is designed as a coupling element, which is provided for connecting with the seat cover SB ( Figure 3 ) connection. In the illustrated embodiment, the second mounting element 15 completely surrounds the frame 13 in the circumferential direction about the normal to the second mirror 12. The second mounting element 15, designed as a coupling element, can, for example, be designed as a flange into which the seat cover SB is circumferentially clamped. Alternatively, the second mounting element 15 can also be designed as a foil or a webbing. In this case, the seat cover can be adhesively bonded or sewn to the second mounting element 15 when the surface element is secured.

[0040] Surface element 1 is designed to visually simulate an opening or through-hole in seat 100. To this end, surface element 1 is designed in the manner of an infinity mirror. Light emitted from depth effect element 14 is reflected multiple times in the gap between two mirrors 11 and 12, with a portion of the reflected light passing rightward through the translucent surface of second mirror 12 during each reflection. This multiple reflection of light in the gap between mirrors 11 and 12 is symbolically represented by the multiple arrows in the gap. Starting from the lower section of depth effect element 14, light first strikes second mirror 12. Half of the light passes rightward through second mirror 12 and is visible to the observer. This is symbolically represented by the arrow pointing rightward from second mirror 12. The other half of the light is reflected by second mirror 12 and directed to first mirror 11. There, it is completely reflected and directed back to second mirror 12. There, half of the light again passes rightward through second mirror 12, and the other half is reflected leftward, toward first mirror 11. This reflection continues, to a certain extent, indefinitely. For an observer looking at the second mirror 12 from the right, the impression is created that the depth effect elements 14 are visible multiple times in succession in the surface element 1. This creates the impression of viewing an opening or through-hole. Thus, the surface element 1 visually simulates an opening with a greater depth, while in reality the surface element 1 has only a small thickness in the direction of the normal to the second mirror 12.

[0041] Figure 2An embodiment of a seat 100 according to the present invention is shown in a schematic perspective view. The seat 100 shown includes a seat cushion element 101, which is configured to seat a person. In addition, the seat 100 includes a backrest element 102, which is connected to the seat cushion element 101. In the embodiment shown, the backrest element 102 is designed to be adjustable relative to the seat cushion element 101 and to vary its inclination. In the embodiment shown, the backrest element 102 includes a backrest 102a, which is connected to the seat cushion element 101. A headrest 102b is arranged on the side of the backrest 102a facing away from the seat cushion element 101, which is configured to support the head of the person sitting on the seat 100. In the embodiment shown, the backrest 102a and the headrest 102b are joined to each other. In the embodiment shown, the seat 100 includes two surface elements 1, which are arranged on the surface of the half of the backrest element 102 facing away from the seat cushion element 101. Here, the second mirror 12 of the two surface elements 1 is directed towards the seat cushion element 101. In this way, a visual simulation of the opening of the seat cushion element 101 produced by the surface elements 1 can be seen. In the embodiment shown, the two surface elements 1 are also arranged in the surface of the backrest element 102, which is located between the backrest 102a and the headrest 102b. In this way, the two surface elements 1 visually produce a separation between the backrest 102a and the headrest 102b. The backrest element 102 is constructed to be closed in the area in which the surface elements 1 are arranged, in particular in the thickness direction below the surface elements 1. In this way, for example, seat foam, supporting structures or other functional elements, such as airbags, can be arranged continuously below the surface elements 1. In this way, the entire backrest element 102 can be designed to be very stable. Figure 2 In the embodiment shown in FIG, two surface elements 1 are arranged side by side on the same surface of the backrest element 102. Alternatively, it is also possible to realize Figure 3 Other embodiments are shown in FIG.

[0042] Figure 3 Three different embodiments a), b) and c) of a backrest element 102 of a seat 100 according to the invention are shown in schematic sectional views. Figure 3 In the figure three cross-sections a), b) and c) can be seen, which show the Figure 2 The section III-III is located between the backrest 102a and the headrest 102b. Figure 2. In this embodiment, the two surface elements 1 are arranged side by side on the same surface of the backrest element 102, and the two second mirrors 12 are oriented in the same direction. In the embodiment shown, the two surface elements 1 are connected to the seat cover SB via their mounting elements 15. Here, the mounting elements 15 are designed as connecting elements, which are connected to the seat cover SB in a force-locking manner, that is, by clamping. The two surface elements 1 are thus integrated into the seat cover SB and are supported in a floating manner relative to the remaining components of the backrest element 102. The shaded area shown inside the backrest element 102 can be used to arrange the seat foam material, the seat support structure or other components of the seat 100.

[0043] The second embodiment shown in section b) is based on the first embodiment shown in section a). However, in the second embodiment, two further surface elements 1 are additionally provided, which are arranged on the surface of the backrest element 102 opposite the first two surface elements 1. In this way, each two surface elements 1 are opposite each other. In the second embodiment, the visual simulation of an opening created by the other surface elements 1 can also be seen from behind the seat 100. In this way, the backrest element 102, viewed from both sides, appears as if an opening or through-hole is arranged in the backrest element between the backrest 102a and the headrest 102b. In addition, in the second embodiment, all surface elements 1 are integrated into the seat cover SB and are respectively connected to the seat cover via mounting elements 15. In the second embodiment, the inner area of the backrest element 122, shown in a shaded manner, is completely available for arranging other components of the seat 100.

[0044] The third embodiment shown in the sectional view c) comprises only one surface element 1, which is arranged within the backrest element 102. The third embodiment is special in that in this surface element 1, both the first mirror 11 and the second mirror 12 each have a translucent mirror surface. This allows the observer to see through the surface element 1, while still perceiving the effect of an infinity mirror. Therefore, in the third embodiment, the entire backrest element 102 can be seen through. The area shown in shaded form, in which the seat foam material, seat support structure, or other components of the seat can be arranged, is divided into two parts in the third embodiment. In addition, in the third embodiment, the surface element 1 is connected to the seat cover SB via a mounting element 15 designed as a connecting element.

[0045] The three embodiments shown in the sectional views a), b) and c) can of course also be combined with one another.
