Description

Technical Field

[0001] The invention relates to a headrest cushion. Background Art

[0002] The seats of motor vehicles usually have a headrest that supports the head when the head moves backward. Such a headrest is a stable component that is padded to a certain extent. However, the headrest often feels hard and therefore feels uncomfortable when the head rests on the headrest. It is known to mount a headrest pad on such a headrest. Such a headrest pad has a padding element that is fixed to the headrest by one or more fastening straps that are wrapped around the headrest. Usually, the one or more fastening straps are firmly fixed to the padding element, so that the height of the padding element in the fastened position is not adjustable and cannot be adjusted according to the height of the person sitting on the seat. Summary of the invention

[0003] Therefore, the object of the present invention is to provide an improved headrest pad.

[0004] In order to achieve the above-mentioned purpose, a headrest pad is proposed according to the present invention, the headrest pad comprising: a cushion element, a hanging cover portion being arranged on the back side of the cushion element; and a fastening belt for fixing the cushion element to the headrest, wherein the fastening belt is guided through the hanging cover portion and wrapped around the headrest by means of one end of the fastening belt, the ends of the fastening belt overlapping when the fastening belt is in a maintained position, wherein the ends can be fixed to each other in a detachable manner by means of a connecting structure arranged in the overlapping area, wherein the hanging cover portion has a plurality of elongated hanging cover sections formed by slits running parallel to each other, wherein the fastening belt is guided through the hanging cover portion in the following manner, namely, in the threading direction, one hanging cover section extends alternately above the fastening belt and one hanging cover section extends alternately below the fastening belt.

[0005] The headrest cushion according to the present invention is composed of a cushion element and a separate fastening belt, by means of which the cushion element can be fixed to the headrest. The hanging sleeve part is arranged on the back side of the cushion element, and the fastening belt is guided through the hanging sleeve part. According to the present invention, the hanging sleeve part does not form only one hanging sleeve, but forms a plurality of separate hanging sleeves. According to the present invention, the hanging sleeve part is provided with a plurality of slits running parallel to each other, through which a plurality of elongated hanging sleeve sections are formed. The fastening belt is then guided through the hanging sleeve part in the following manner, that is, in the threading direction, one hanging sleeve section is alternately above the fastening belt and one hanging sleeve section is alternately below the fastening belt. The fastening belt is thus similar to being woven / braided through continuous hanging sleeve sections, so that the hanging sleeve sections are alternately clamped above and below the fastening belt. Thus, a corresponding contact surface is formed between the fastening belt and the hanging sleeve section, whereby direct surface contact is obtained, wherein corresponding friction exists between the fastening belt and the hanging sleeve section in each contact area. In the installed or use position, the fastening strap is guided from bottom to top through the hanging hook section and then extends around the headrest above and below, wherein the ends of the fastening strap overlap and the fastening strap is fixed in the overlapping area via a suitable connection structure so that the fastening strap can be pulled sufficiently tight around the headrest. Therefore, due to this orientation of the fastening strap, the cushion element can be moved vertically along the fastening strap, that is, the hanging hook part moves along the fastening strap that is fixed in position, so that the height of the cushion element can be adjusted vertically in a simple manner. At the same time, due to the multiple contact surfaces located at different heights / levels between the fastening strap and the hanging hook section, a sufficiently large friction is obtained, which ensures that the cushion element remains in the desired vertical position and therefore does not slide down along the fastening strap, and the position can be maintained even when small forces are generated during normal driving operation (for example when driving over uneven roads). This is because a sufficient mechanical coupling is provided by the braided connection between the fastening strap and the hanging hook part, but at the same time still allows height adjustment.

[0006] Here, as described above, a plurality of mutually parallel slits are provided, thereby also forming a plurality of hanging segments. According to the invention, at least three slits are provided, but preferably at least five slits are provided, particularly preferably seven slits are provided. As the number of slits increases, more hanging segments are obtained, so that as the number of hanging segments increases, the resulting braided structure becomes more complex, i.e., there are more individual contact areas extending above and below the tightening strap.

[0007] Preferably, the width of the fastening belt is substantially equivalent to the width of the slit, thereby ensuring that each corresponding slit is almost completely filled with the fastening belt in its width and the fastening belt can be passed vertically, but at the same time the hanging sleeve part itself and thus the cushion element itself cannot move horizontally relative to the vertically extending fastening belt.

[0008] Preferably, the fastening belt itself has a band-shaped inner part surrounded by an outer cover, wherein the inner part has a greater rigidity than the material of the outer cover. The outer cover is, for example, a fabric, wherein the outer cover can also be composed of a plurality of fabric sections interwoven with one another. The inner part is composed of a relatively hard material, so that sufficient rigidity is obtained in the transverse direction, thereby ensuring that the fastening belt is not pushed together in the transverse direction, but is essentially transversely rigid or transversely stable. This also serves additionally to prevent horizontal displacement of the cushioning element relative to the fastening belt.

[0009] Preferably, the flat, strip-shaped or film-shaped inner part is made of a synthetic material, for example EPDM (ethylene-propylene-diene monomer / ethylene propylene diene monomer), but other similar film-shaped synthetic materials can of course also be used, that is, the present invention is not limited thereto.

[0010] As mentioned above, the fastening belt overlaps in its end region when it is in the installation position, wherein a connecting structure is provided in the overlapping region, and the two ends of the fastening belt are connected to each other via the connecting structure. The connecting structure can have different properties. For example, the connecting structure is a flat Velcro connector (Klettverbinder), that is, a Velcro is provided. In the overlapping region, the first Velcro section or the first Velcro layer (i.e., the layer with the Velcro hook surface) is arranged on one end of the fastening belt, and the corresponding second Velcro section or the second Velcro layer that can be hooked with the Velcro hook surface is arranged on the other end of the fastening belt. The second Velcro section or the second Velcro layer is usually significantly larger than the first Velcro section or the first Velcro layer (i.e., the hook section) in terms of area, so that the corresponding Velcro connection can be carried out on a corresponding large area. Instead of using Velcro, it is also possible to consider arranging a plurality of button connectors arranged in different positions. Therefore, corresponding button components are arranged in succession at the two ends of the fastening belt in the vertical direction, and the button components can be buckled or locked to each other. The corresponding button connections can then be snapped together, depending on the degree to which the tightening strap is to be tightened to achieve a tight fit.

[0011] The main element for forming the woven connection is a hanging part with multiple slits arranged on the back side of the cushion element. For this purpose, it is advantageous if the cushion element has an inner cushion, for example made of soft foam plastic or a similar material, and a cushion cover. In this case, the hanging part is either sewn or glued to the cushion cover. The cushion cover is made of, for example, fabric (Stoff) or textile (Gewebe), but the cushion cover can also be made of soft leather or a similar material. Since the hanging part is located on the back side, it is not visible in the installed position because the hanging part is covered by the headrest, so the hanging part can be made of any material. However, preferably, the hanging part is made of the same material as the cushion cover, so as to achieve a visually consistent appearance. This is advantageous because, as described, the cushion element and the fastening belt are separate components, and the fastening belt must be woven through the hanging part at least once to achieve installation.

[0012] In addition to the headrest pad itself, the invention also relates to a motor vehicle comprising at least one seat with a headrest arranged on the seat and a headrest pad of the above-described type which is fastened or can be fastened to the headrest. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Further advantages and details of the invention emerge from the exemplary embodiments described below and with reference to the drawings.

[0018] Figure 4 Show Figure 3 Arrangement of a headrest pad on a headrest of a motor vehicle seat. DETAILED DESCRIPTION

[0019] Figure 1The schematic diagram of the principle shows an exploded view of a headrest cushion 1 according to the invention, which comprises a cushion element 2 and a cushion cover 3, the cushion element being composed of a sufficiently soft inner cushion (not shown in detail), for example, of foam plastic, and the cushion cover being composed, for example, of fabric or sufficiently soft leather. A hanging cover part 4 is arranged on the back side of the cushion element 2, the hanging cover part being composed, for example, of the same material as the cushion cover 3. The hanging cover part is connected to the cushion cover 3 in the region of its side edge 5, preferably by sewing. There is no connection in the region of the lower edge 6 and the upper edge 7, so that the fastening belt can be guided under the hanging cover part 4 in these edge regions.

[0020] The suspension part 4 itself is formed by being slit by a plurality of, in the illustrated embodiment, a total of seven mutually parallel slits 8, all of which preferably have the same length, thereby forming a plurality of individual suspension segments 9, in the present case a total of eight suspension segments 9, which are necessarily also mutually parallel. Preferably, the suspension segments have the same width when viewed vertically.

[0021] Figure 1 Also shown is a fastening strap 10, which is used to fix the cushion element 2 on the headrest. The fastening strap is designed to be correspondingly long so that (as will be described in detail below) it can be woven through the hanging part 4 or the slit 8 on the one hand, and on the other hand it is long enough to surround the headrest and be fixed to the headrest. The width of the fastening strap 10 is substantially equivalent to the width of the slit 8, so that when the fastening strap 10 is woven through, the cushion element 2 cannot slide sideways relative to the fastening strap 10.

[0022] like Figure 2 As shown in the cross-sectional view of the embodiment, the fastening belt 10 is composed of a band-shaped inner part 11, which is composed of a sufficiently rigid material, preferably a synthetic material such as EPDM, that is, a correspondingly stable but sufficiently flexible synthetic material film. The inner part is surrounded by an outer cover 12, which is composed of two separate layers, namely, a first layer 13 forming the visible side and a second layer 14 sewn to the first layer, the first layer being composed of the same material as the pad outer cover 3, for example, and the second layer being a Velcro layer, for example, which is part of the connection structure. As shown in the example, if the connection structure is implemented as Velcro, a Velcro layer 15 with a Velcro hook surface that is only partially applied is provided on the outer layer 13, and layer 14 is a Velcro layer that is hooked to the Velcro hook surface. Since the two ends of the fastening belt overlap in the installation position, a corresponding connection is formed by the Velcro layers 14, 15 to fix the fastening belt 10 in the tightened installation position.

[0023] Figure 3A schematic diagram of the principle of a headrest cushion 1 according to the present invention is shown, wherein a fastening strap 10 is fixed to a cushion element 2. Obviously, the fastening strap 10 is woven through the hanging sleeve portion 4, wherein the fastening strap 10 is woven through a row of slits 8 and thus through a row of hanging sleeve sections 9. Obviously, when viewed along the threading direction, one hanging sleeve section 9 is always located above the fastening strap 10 and the next hanging sleeve section 9 is located below the fastening strap in an alternating manner. Due to the formed weaving structure, a corresponding number of contact surfaces are obtained on both the upper and lower sides of the fastening strap 10, thereby obtaining a sufficient number of contact positions and thus friction positions, which prevent the cushion element 2 from sliding downward on the fastening strap 10 fixed to the headrest. At the same time, however, the cushion element can be moved downward or upward along the fastening strap 10 and its position adjusted by using appropriate force. As shown in FIG. Figure 3 As shown, the width of the tightening strap 10 corresponds essentially to the width of the slit 8 , so that the tightening strap 10 is received essentially in a form-fitting manner in the respective slit 8 .

[0024] Figure 4 A detail of a motor vehicle according to the invention is shown, wherein a seat 16 has a seat part 17 and a backrest part 18, and a headrest 19 is provided on the upper side of the backrest part, and the headrest 19 can usually be adjusted vertically relative to the backrest part. A headrest pad 1 according to the invention is arranged on the headrest 19, wherein, obviously, a cushioning element 2 is arranged on the front side of the headrest 19, and a fastening belt 10 surrounds the headrest 19 in a vertical winding direction. The overlapping belt ends of the fastening belt 10 are fixed to the back side of the headrest 19 by corresponding connecting structures 20 formed by Velcro layers 14, 15. As indicated by the double arrow P, the cushioning element 2 can be moved vertically along the fastening belt 10 and can thus be adjusted in height, and since the fastening belt 10 is wound sufficiently tightly, it will not change its position on the headrest 19, and at the same time, due to the woven connection between the hanging part 4 and the fastening belt 10, the cushioning element 2 will not accidentally slip off the fastening belt 10.
