Description

Technical Field

[0001] The invention relates to a seat covering including at least one covering material and a covering retainer, and a seat, in particular a vehicle seat. Background Art

[0002] Seats, such as vehicle seats, are usually provided with seat coverings. It is also known to removably fasten the seat covering to the seat, for example, to remove or replace the seat covering.

[0003] Technical Problem

[0004] The invention is based on the task of improving seat coverings of the type initially described, in particular making them seamless, and providing a corresponding seat, in particular a vehicle seat. Summary of the Invention

[0005] Regarding the seat covering, the invention solves the technical problem by the features recited in claim 1. Regarding the seat, the invention solves the technical problem by the features recited in claim 7.

[0006] The technical problem is solved according to the invention by a seat covering including at least one covering material and a covering retainer arranged on the covering material for holding the covering material on a seat cushion, wherein the covering retainer includes at least two carriers that are partially connected to each other, and at least one fastening element is provided on the carrier parts where they are connected to each other, and on their parts not connected to each other they are each connected, in particular by material adhesion, such as gluing, to the invisible surface side of the covering material, the invisible surface side of the covering material facing away from the visible surface side of the covering material.

[0007] The fact that the covering retainer includes at least two carriers that are partially connected to each other, and these carriers are provided with at least one fastening element on their connected carrier parts and are each connected to the covering material on their unconnected carrier parts means that the covering retainer can be connected to the seat cushion and to the covering material in a simple manner on the one hand and on the other hand.

[0008] In other words, the carrier elements are connected to each other, in particular firmly connected to each other, at a first carrier end on the one hand, and are connected to, in particular firmly connected to, the invisible surface side of the covering material at a relative second carrier end on the other hand. The first carrier part forms the first carrier end. The second carrier part forms the second carrier end.

[0009] The covering retainer is located on the invisible surface side of the covering material.

[0010] The cover retainer is fastened to the invisible surface side of the cover material by material bonding, which means that a seamless or seam-free seat cover can be provided to increase seat comfort and improve the visual appearance. The seat cover can have a flat or planar surface side.

[0011] The seat cover according to the invention can be designed in such a way that the cover fastened to the seat cushion can be "hidden". The cover retainer, which is fixed to the cover material by material bonding and in a seamless manner, enables a "hidden downward installation", whereby a smooth appearance can be achieved on the A surface of the seat cover without visible fastening on the inside.

[0012] Advantageous embodiments, which can be used alone or in combination with each other, are the subject of the dependent claims.

[0013] The carrier parts of the carrier that are not connected to each other can form a connection surface for connection to the seat cover.

[0014] The second carrier part can be designed as a free end and protrude away from each other in such a way that the second carrier part (i.e., the second carrier end) has or forms a flat connection surface facing the invisible surface side of the cover material.

[0015] The unconnected second carrier parts can, for example, protrude away from each other in such a way after the connection area of the connected first carrier parts that the second carrier parts form a flat connection surface facing the invisible surface side of the cover material.

[0016] The respective connection surfaces of the carrier elements are all connected to the invisible surface side of the cover material facing away from the visible surface side of the cover material, in particular by material bonding (such as gluing), which enables a seamless surface side and a uniform outer contour of the cover material without visible joints, indentations, stitches, welds or visible fastenings.

[0017] In other words, the seat cover can maintain the smooth appearance of its A surface.

[0018] The carrier elements can each be formed by a layer of non-woven fabric. Using carrier elements formed by non-woven fabric makes it easy to fasten the cover retainer to the cover material seamlessly. In addition, the non-woven fabric layer can be made strong and relatively thin so that the visual appearance is not affected even after the carrier elements have been fastened to the cover material.

[0019] The non-woven fabric layers can be joined together in a first area, in particular at their first carrier parts. The non-woven fabric layers can be exposed in a second area, in particular to form free second carrier parts.

[0020] The carrier can be a nonwoven carrier. The carriers can each be formed from a nonwoven material or a nonwoven fabric. The carriers can each be formed from a netting material, a woven fabric, a knitted fabric or a knitted fabric made of fibers. The carriers formed from nonwoven fabrics can be joined together in a simple manner, such as by gluing and / or sewing. In addition, the carriers formed from nonwoven fabrics can be connected to the covering material in a simple manner, in particular by gluing.

[0021] The second carrier part can be connected to the invisible surface side of the covering material via an adhesive layer.

[0022] The adhesive layer can be arranged between the connecting surfaces of the covering material and the carrier. For example, the adhesive layer can be applied to the corresponding surface side of the covering material and then connected to the connecting surface. Alternatively, or optionally additionally, the adhesive layer can already have been applied to the connecting surface. In this case, the connecting surface of the carrier can already have been provided with an adhesive, for example by impregnation.

[0023] The fastening element can include at least one connecting hook, connecting line, loop, pocket, hemming element and / or connecting ring.

[0024] Furthermore, the invention relates to a seat, in particular a vehicle seat, comprising a seat cushion and a seat covering which is removably fastenable or fastened to the seat cushion and has the above-mentioned features.

[0025] The seat cushion can include at least one groove in which a retaining element is arranged.

[0026] The covering retainer can be introduced or introduced into the groove by means of its first carrier part and the fastening element for fastening the seat covering to the seat cushion, wherein the fastening element can engage or engages with the retaining element.

[0027] The retaining element can include at least one retaining clip, staple ring, hog ring and / or retaining line and / or can be formed by a component of the padding, such as a cushioning pad.

[0028] Furthermore, the invention can relate to a method for producing a seat covering having the above-mentioned features.

[0029] In a first method step, carrier elements, for example in the form of nonwoven fabric layers, are joined together via the first carrier part, for example by a pressure bonding process at room temperature. In a second method step, the unsupported, unconnected carrier parts of the carrier elements, in particular the carrier parts opposite the first carrier part, are folded apart. The second carrier parts are moved apart in such a way that they form a flat connecting surface, and then the covering material is provided to this surface. The connecting surface is provided with an adhesive layer and / or adhesive and is connected to the covering material by material bonding. Description of the Drawings

[0035] In all the drawings, corresponding parts have the same reference numerals. Detailed Description of the Invention

[0036] Hereinafter, the vehicle seat 100 schematically shown in Figure 1 will be described using three mutually perpendicular spatial directions. In the vehicle seat 100 installed in a vehicle, the longitudinal direction x extends substantially horizontally and preferably parallel to the longitudinal direction of the vehicle, which corresponds to the normal traveling direction of the vehicle. The transverse direction y extending perpendicular to the longitudinal direction x is also horizontally oriented in the vehicle and extends parallel to the transverse direction of the vehicle. The vertical direction z extends perpendicular to the longitudinal direction x and perpendicular to the transverse direction y. In the case of the vehicle seat 100 installed in a vehicle, the vertical direction z preferably extends parallel to the vehicle vertical axis.

[0037] The position information and orientation information used, such as front, rear, top, and bottom, refer to the line of sight direction of an occupant sitting in the vehicle seat 100 in a normal sitting position, where the vehicle seat 100 is installed in a vehicle in a use position suitable for passenger transportation, with the backrest 104 upright and facing the traveling direction as usual. However, the vehicle seat 100 can also be installed or moved in a different orientation, such as transverse to the traveling direction. Unless otherwise specified, the vehicle seat 100 is configured to be mirror-symmetrical with respect to a plane extending perpendicular to the transverse direction y.

[0038] The backrest 104 can be pivotally arranged on the seat part 102 of the vehicle seat 100.

[0039] The vehicle seat 100 includes at least one seat cushion 106, such as a foam part. The seat cushion 106 is provided with a seat covering 110. The seat covering 110 can be made of, for example, textiles, leather or another natural material or natural fabric.

[0040] Figure 2 A sectional view of the seat cushion 106 provided with the seat covering 110 is shown.

[0041] The seat cushion 106 includes at least one groove 108. The seat cushion 106 can have a plurality of grooves 108. The grooves 108 can be formed, for example, as one or more channels.

[0042] The seat cushion 106 can be a seat part cushion and / or a backrest cushion. The recess 108 or the plurality of recesses 108 can be formed as foam parts.

[0043] Each of the grooves 108 or the plurality of grooves 108 can define an attachment socket for attaching the seat covering 110 and receiving a covering holder 120 provided on the seat covering 110.

[0044] The seat covering 110 includes at least one covering material 112 and at least one covering holder 120 provided on the covering material 112 for holding and fastening the covering material 112 to the seat cushion 106. The covering material 112 can be formed of, for example, textiles, leather or other natural materials or natural fabrics. The covering material 112 can, for example, include a plurality of covering layers bonded together.

[0045] The covering material 112 has a visible surface side 114 (also referred to as the A surface) and a surface side 116 that is not visible to the occupant (also referred to as the B surface). The covering material 112 is applied to the seat cushion 106 in such a way that the visible surface side 114 faces upward or toward the occupant, while the non-visible surface side 116 faces the seat cushion 106.

[0046] The covering holder 120 includes at least two carriers 122, also referred to as carrier elements 122, which are partially connected to each other. Each of the carriers 122 or carrier elements 122 can be a non-woven carrier. Each of the carriers 122 can be formed of a non-woven material or non-woven fabric. Each of the carriers 122 can be formed of a mesh material, a woven fabric, a knitted fabric or a knitted fabric made of fibers.

[0047] For example, each of the carriers 122 can be formed of an extruded non-woven fabric. The carrier 122 can be a spunbond non-woven fabric. The carrier 122 can be a homogeneous, uniform planar non-woven layer. The extrusion process is a process for forming a homogeneous, uniform planar non-woven fabric. The carrier 122 can form an extruded double non-woven layer.

[0048] Each of the carriers 122 has a first (e.g., lower) carrier part 124 and an adjacent second (e.g., upper) carrier part 126. The first carrier part 124 forms a first carrier end of the cover holder 120, while the second carrier part 126 forms a second carrier end of the cover holder 120.

[0049] The carriers 122 are firmly connected to each other at their first carrier parts 124. For example, the first carrier parts 124 can be connected to each other at least by material adhesion and / or in a form-locking manner. For example, the first carrier parts 124 can be glued and / or sewn together.

[0050] The interconnected first carrier parts 124 are provided with at least one fastening element 130. The fastening element 130 can be a connecting hook 132. The fastening element 130 can have a substantially oval body and, for example, two hook elements protruding from the body.

[0051] The fastening element 130 can be designed as a so-called "listing pocket", for example in the form of a loop or a pocket, and can have a fastening line arranged therein.

[0052] To fasten the seat cover 110 to the seat cushion 106, the fastening element 130 can be inserted into a groove 108 provided for this purpose and connected to (e.g., clamped or hooked to) a retaining element 140 arranged in the groove 108. The retaining element 140 can be foamed into the seat cushion 106. The retaining element 140 can be, for example, a retaining clip 142, such as a bracket element, a clamping element, a clip element, a hook element, a staple loop or a so-called hog ring.

[0053] The carriers 122 are not connected to each other at their second carrier parts 126, i.e., they are separated from each other. The second carrier parts 126 are formed as free ends. The carriers 122 can each be connected to or are connected to the covering material 112 at their second carrier parts 126, and the second carrier parts 126 are not connected to each other.

[0054] In particular, the fastening holder 120 is connected to the invisible surface side 116 of the covering material 112 facing away from the visible surface side 114 of the covering material 112 via the second carrier part 126, in particular by material adhesion, such as gluing.

[0055] Since the second carrier parts 126 are not connected to each other, they can each form a connection surface 128 suitable for fixedly connecting to the covering material 112.

[0056] The second carrier parts 126 are oriented away from each other or folded in such a way that the surfaces of the second carrier parts 126 facing the covering material 112 form connection surfaces 128 for connection to the covering material 112, while the surfaces facing away from the covering material 112 form support surfaces for supporting on the seat cushion 106 and covering the recess 108 of the seat cushion 106.

[0057] The surfaces of the respective second carrier parts 126 facing the seat cushion 106 can rest on the seat cushion 106 in the region of the recess 108. The recess 108 can be completely covered by the second carrier parts 126 protruding away from each other.

[0058] The connection surfaces 128 are each connected to the invisible surface side 116 of the covering material 112 facing away from the visible surface side 114 of the covering material 112, in particular by material bonding, for example gluing.

[0059] An adhesive layer 150 can be arranged between the covering material 112 and the second carrier parts 126, in particular between their connection surfaces 128. The second carrier parts 126 can already be provided with an adhesive, for example impregnated.

[0060] The covering material 112 and the carrier 122 can be connected to each other by pressure, for example at room temperature. Then the covering material 112 can be fixed to the seat cushion 106 using the covering retainer 120. For example, using conventional fastening methods, such as using loops and / or clips, the covering material 112 can be fastened to the seat cushion 106 using the covering retainer 120. The covering retainer 120 enables the so-called "hidden drop-down", whereby a smooth appearance can be achieved on the A surface of the seat covering 110 without visible fastening on the inside.

[0061] In an alternative exemplary embodiment, the carrier 122 can be formed in one piece. In other words, the covering retainer 120 can include a single carrier 122 and second carrier parts 126 adjacent to the first carrier part 124. The single carrier 122 can include the first carrier part 124, and the first carrier part 124 can be provided with fasteners 130, where the second carrier parts 126 can be separated into two connection surfaces 128 by a separation process. The carrier 122 can be an extruded nonwoven carrier.

[0062] Figure 3 A sectional view of a seat cushion 106 provided with a seat covering 110 according to a second exemplary embodiment is shown.

[0063] The connected first carrier part 124 is provided with at least one fastening element 130. The fastening element 130 can be a hemming element 134, for example a circular or oval hemming element 134.

[0064] To fasten the seat covering 110 to the seat cushion 106, the fastening element 130 can be inserted into the groove 108 provided for this purpose and connected to (e.g., clamped or hooked to) the retaining element 140 arranged in the groove 108. The retaining element 140 can be foamed into the seat cushion 106. The retaining element 140 can be, for example, the retaining wire 144.

[0065] The hemming element 134 can be fastened to the retaining wire 144 by the connecting loop 136. The connecting loop 136 can surround the hemming element 134 and the retaining wire 144.

[0066] Figure 4 A sectional view of a seat cushion 106 provided with a seat covering 110 according to a third exemplary embodiment is shown.

[0067] The first carrier part 124 of the connection is provided with at least one fastening element 130. The fastening element 130 can be a connecting wire 138, such as a PP wire and / or a metal wire.

[0068] To fasten the seat covering 110 to the seat cushion 106, the fastening element 130 can be inserted into the groove 108 provided for this purpose and connected to (e.g., clamped or hooked to) the retaining element 140 arranged in the groove 108. The retaining element 140 can be foamed into the seat cushion 106. The retaining element 140 can be formed by components, such as the wire components and / or strip components of the pad 146, for example, a flexible pad, a suspension pad, and / or a cushioning pad.

[0069] The connecting wire 138 can be fastened to the pad 146 by the connecting clip 160 (e.g., a plastic clip), and the connecting clip 160 passes through the foam of the seat cushion 106. The connecting clip 160 can surround the connecting wire 138 and the components of the pad 146.
