Description

Technical Field

[0001] The invention relates to a seat trim element and a vehicle seat having the features of the preamble of claim 1 . Background Art

[0002] Seat trim elements for vehicle seats are generally known from the prior art. The seat trim element can be, for example, a seat covering element, in particular a seat cover, or a seat cushion element, in particular a cushion shell. The seat cushion element is generally arranged on a support structure, for example a support frame of the vehicle seat. For example, the seat cushion element can be arranged on the seat cushion element and connected thereto. It is also known to three-dimensionally shape such a seat covering element in order to achieve a molded seat contour. Summary of the invention

[0003] Technical issues

[0004] The problem addressed by the present invention is to improve a seat trim element of the type mentioned at the outset, in particular to make it variable, and to provide a corresponding vehicle seat.

[0005] Solution

[0006] According to the invention, the first problem mentioned above is solved by a seat trim element having the features of claim 1. The second mentioned problem is solved by a vehicle seat having the features of claim 8.

[0007] Advantageous embodiments which can be used alone or in combination with one another are subject matter of the dependent claims.

[0008] The seat decoration element according to the present invention is designed as a three-dimensional molded seat covering element and / or a three-dimensional molded seat cushion element of a vehicle seat, comprising at least one three-dimensional molded insert (also called 3D additional module or 3D insert or 3D decoration module) produced by a thermoforming process, which can be attached or detachably attached to the seat decoration element.

[0009] The fact that the insert can be three-dimensionally preformed and removably and thus interchangeably attached to the three-dimensionally formed seat trim element reduces seam lines. In addition, complex areas of the seat trim element, such as concave decorative areas, decorative grooves, etc., can be three-dimensionally and removably attached to the seat trim element in a simple manner or retrofitted to an existing seat trim element.

[0010] Thermoforming processes are particularly the thermoforming of materials, in particular plastic materials, such as plastic fiber materials, using pressure and heat and / or high-frequency welding (also called HF welding). Thermoforming processes can be carried out in a forming tool formed from two tool halves, for example, to produce three-dimensional designs of inserts or additional modules.

[0011] The outer side of the three-dimensionally formed insert can be designed as a decorative surface or at least partially designed decoratively. The inner side of the three-dimensionally formed insert can be designed as a support element or a fastening element, for example. Alternatively or additionally, one or more fastening elements, such as push-in flaps and / or sewing flaps, can be provided on the three-dimensionally formed insert.

[0012] The three-dimensionally shaped insert part can in particular be formed from a three-dimensionally deformable and / or compressible and / or curable and / or stabilizable material, in particular a fiber material, in particular a non-woven plastic material or another suitable plastic fiber material. For example, the material thickness of the three-dimensionally shaped insert part can be between 1 mm and 5 mm, in particular between 2 mm and 3 mm. In particular, the three-dimensionally shaped insert part can be inherently rigid, in particular be formed from such a material, and / or can have such a material thickness that the insert part is inherently rigid.

[0013] For example, the three-dimensionally shaped insert can have a material structure of at least one three-dimensionally deformable plastic nonwoven (also called nonwoven) or similar material, in particular a 3D-shaped plastic material, such as a polymer fiber material, for example a polyester fiber material, a polyethylene fiber material, wherein the three-dimensionally deformable plastic material is compressed through its material thickness by three-dimensional deformation and stabilized in a three-dimensional shape. The material can also contain fibers with a low melting point.

[0014] Another possibility is a material structure with one or more layers, in particular with a surface layer and / or a carrier layer, for example made of an additional surface material or carrier material. In this case, the surface layer can be fixed to the carrier material by an adhesive layer. The adhesive layer can be pre-fixed to the raw material of the carrier layer or the surface layer, or can be formed as a separate material layer. Alternatively, the three-dimensionally formed insert can be formed only from a single layer of material, in particular from a non-woven material layer or a plastic material layer that simultaneously forms the outer side and the inner side. For example, the insert can be three-dimensionally preformed (thermoformed), and the upper surface can be formed by a covering material, in particular vinyl, fabric and / or leather and / or molded embossing, and the lower surface can be formed by a three-dimensionally formed fiber material, in particular a plastic fiber material, to form part of a three-dimensionally formed decorative part.

[0015] The three-dimensional molded insert can be, for example, a three-dimensional molded cushion insert, in particular a three-dimensional molded seat cushion element and / or a three-dimensional molded seat covering element, a three-dimensional molded shoulder support element and / or a three-dimensional molded neck support element and / or a three-dimensional molded armrest recess and / or a three-dimensional molded armrest element.

[0016] The seat trim element may be, for example, a three-dimensionally formed seat cushion element or a three-dimensionally formed seat covering element.

[0017] The insert can be, for example, a seat back insert (also called a seat back panel), a shoulder insert (also called a shoulder panel), a neck insert (also called a neck panel), an armrest insert (also called an armrest panel), a seat side insert (also called a seat side panel) or a fastening insert (also called a fastening panel).

[0018] As described above, the vehicle seat according to the present invention includes at least one supporting structure and a seat trim element arranged on the supporting structure.

[0019] The seat trim element may be a seat cushion trim element, a seat back trim element, a seat headrest trim element, and / or a seat armrest trim element.

[0020] In other words: In summary, the present invention provides a cushion insert (also called insert) which is 3D formed using a thermoforming process and can be attached to a seat trim element. The cushion insert can be manufactured, for example, by HF welding technology or other thermoforming technologies. The 3D preformed center seat cushion insert can be part of a vehicle cushion cover for a second or third row rear seat cushion in a vehicle. The insert can replace at least a part of a conventional seat cover. It can be sewn to the seat cover or attached in other ways. The three-dimensional preformed insert can also be removable and replaceable to facilitate maintenance and personalization / modularity.

[0021] 3D preforming of the insert reduces seam lines. In addition, complex areas of the seat trim elements can be realized by 3D preforming of the insert, such as recesses for storage, such as bottle holders.

[0022] The invention can provide storage options in an insert, such as a holder for mobile devices or other components, which can in particular be molded. The material structure comprises at least one 3D moldable nonwoven or similar material, which has its material thickness compressed by 3D preforming and is stabilized in a 3D shape. The material can also contain fibers with a low melting point. Another possibility is a material structure with one or more layers of additional surface material. In this case, the surface material layer is fixed to the carrier material by an adhesive layer. The adhesive layer can be pre-fixed to the raw material or can be present as a separate material layer.

[0035] The following uses three mutually perpendicular spatial directions to describe the related art Figure 1 Schematically shown in the vehicle seat 100. In the vehicle seat 100 installed in the vehicle, the longitudinal direction x extends substantially horizontally and preferably parallel to the longitudinal direction of the vehicle, which corresponds to the usual driving direction of the vehicle. The transverse direction y extending perpendicularly to the longitudinal direction x is also aligned with the vehicle horizontally and extends parallel to the transverse direction of the vehicle. The vertical direction z extends perpendicularly to the longitudinal direction x and perpendicularly to the transverse direction y. With the vehicle seat 100 installed in the vehicle, the vertical direction z preferably extends parallel to the vertical axis of the vehicle.

[0036] The position information and direction information used, such as front, rear, top and bottom, refer to the viewing direction of an occupant sitting in the vehicle seat 100 in a normal seating position, wherein the vehicle seat 100 is installed in a vehicle, and in a use position suitable for passenger transportation, the backrest 104 is vertical as usual and aligned in the direction of travel. However, the vehicle seat 100 can also be installed or moved in a different direction, for example transversely to the direction of travel. 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.

[0037] The backrest 104 can be arranged pivotably on the seat part 102 of the vehicle seat 100. For this purpose, the vehicle seat 100 can optionally comprise a fitting 106, in particular an adjustment fitting, a rotation fitting, a latch fitting or a swing fitting.

[0038] Position and direction designations used, such as radial, axial, and circumferential designations, refer to the rotation axis 108 of the fitting 106. Radial refers to perpendicular to the rotation axis 108. Axial refers to in the direction of or parallel to the rotation axis 108.

[0039] The vehicle seat 100 may optionally include a longitudinal adjustment device 110. The longitudinal adjustment device 110 comprises, for example, a track arrangement 112 having a first track element 114 and a second track element 116. The first track element 114 is adjustable in the longitudinal direction x relative to the second track element 116. The first track element 114 is attached to the seat part 102. The second track element 116 is attached to a structural element of the vehicle, for example a vehicle floor.

[0040] For the sake of clarity, the first track element 114 is referred to in the following description as the top track 114. The top track 114 (also referred to as a running track or a slider) is associated with the vehicle seat 100 and is designed to support the vehicle seat 100. The second track element 116 is referred to hereinafter as the bottom track 116. The bottom track 116 is fixed and connected to, for example, the floor of the vehicle.

[0041] Figure 2 The vehicle seat 100 is shown in a perspective view as a seat row 120 with a plurality of seat parts 122.1 to 122.3. Instead of a seat row 120, the vehicle seat 100 can also be designed as a single seat (not shown in detail). In particular, the seat row 120 can be arranged at the rear of the vehicle.

[0042] In the example shown, the seat row 120 comprises two outer (particularly wider) seat sections 122 . 1 and 122 . 3 and a central (particularly narrower) seat section 122 .

[0043] The corresponding seat portions 122.1 to 122.3 each include a seat surface portion 124.1 to 124.3 (similar to Figure 1 The seat portion 102 in FIG. 1 and the backrest portions 126.1 to 126.3 (similar to Figure 1 The backrest 104 in the embodiment of the present invention. The seat surface parts 124.1 to 124.3 can be formed as a continuous seat workbench. Alternatively, the seat surface parts 124.1 to 124.3 can also be formed as separate seat surfaces (not shown). The backrest parts 126.1 to 126.3 can be designed as separate, in particular individually adjustable backrests 104.

[0044] like Figure 2 The seat row 120 shown in the example in comprises a three-dimensionally formed seat decoration element 130. The three-dimensionally formed seat decoration element 130 can be designed as a three-dimensionally formed seat covering element or a three-dimensionally formed chair seat cushion element, as described, for example, in DE 10 2018 202 153 A1 or WO 2019 / 155046A1.

[0045] The seat trim element 130 may be, for example, a seat cushion trim element 130 . 1 , a seat back trim element 130 . 2 , a seat headrest trim element 130 . 3 and / or a seat armrest trim element 130 . 4 .

[0046] The seat trim element 130 is arranged and held in a manner not shown in detail on a supporting structure of the respective seat part 122 . 1 to 122 . 3 .

[0047] According to the invention, the vehicle seat 100 formed as a seat row 120 comprises a plurality of three-dimensionally formed inserts 132.1 to 132.5. The inserts 132.1 to 132.5 are three-dimensionally formed in a thermoforming process. The inserts 132.1 to 132.5 can be attached to the respective associated seat trim element 130, in particular detachably or exchangeably attached.

[0048] The corresponding three-dimensionally shaped insert parts 132 . 1 to 132 . 5 produced by a thermoforming process are also referred to as 3D additional modules or 3D insert parts or 3D decorative modules.

[0049] The fact that the respective insert pieces 132 . 1 to 132 . 5 are three-dimensionally preformed and can be detachably and thus exchangeably attached to the associated three-dimensionally formed seat trim element 130 reduces seam lines.

[0050] In particular, a thermoforming process is understood to mean the thermoforming of a material, in particular a plastic material, such as a plastic fiber material, by means of pressure and heat and / or high-frequency welding (also called HF welding). The thermoforming process can be carried out in a forming tool, which is formed, for example, from two half-tools, for producing the three-dimensional configuration of the respective insert 132.1 to 132.5.

[0051] The respective inserts 132.1 to 132.5 may be preformed, in particular thermoformed, for example, by a thermoforming process and may have an upper surface made of a covering material, in particular vinyl, fabric and / or leather, optionally with a molded embossing. The lower surface of each insert 132.1 to 132.5 may be formed of a three-dimensionally formed fiber material to form part of a three-dimensionally formed trim element.

[0052] The outer side of the respective three-dimensionally formed insert 132.1 to 132.5 can be designed, for example, as a decorative surface or at least partially as a decorative surface. The inner side of the respective three-dimensionally formed insert 132.1 to 132.5 can be designed, for example, as a supporting element or a fastening element. Alternatively or additionally, one or more fastening elements, for example push-in flaps and / or sewing flaps, can be provided on the respective three-dimensionally formed insert 132.1 to 132.5.

[0053] The respective three-dimensionally shaped inserts 132.1 to 132.5 can be formed in particular from a three-dimensionally deformable and / or compressible and / or curable and / or stabilizable material, in particular a fiber material, in particular a nonwoven plastic material or another suitable plastic fiber material. For example, the respective three-dimensionally shaped inserts 132.1 to 132.5 can have a material thickness of between 1 mm and 5 mm, in particular between 2 mm and 3 mm.

[0054] The corresponding three-dimensionally shaped inserts 132.1 to 132.5 can also have a shaped material structure, at least one three-dimensionally deformable plastic nonwoven (also called nonwoven) or similar material, in particular a 3D-shaped plastic material, such as a polymer fiber material, such as a polyester fiber material, a polyethylene fiber material, wherein the three-dimensionally deformable plastic material is compressed in its material thickness by three-dimensional deformation and stabilized in a three-dimensional shape. The material can also contain fibers with a low melting point.

[0055] The first three-dimensionally formed insert 132.1 can be, for example, a seat surface insert (also called seat panel), for example a three-dimensionally formed front cushion insert for the front seat surface parts 124.1 and 124.3, in particular a three-dimensionally formed seat surface cushion element and / or a three-dimensionally formed seat surface covering element. The first three-dimensionally formed insert 132.1 is, for example, used to support the thigh area of ​​a user or occupant sitting in the seat parts 122.1 and 122.3. The first three-dimensionally formed insert 132.1 can be detachably or interchangeably connected (e.g., sewn, clamped, etc.) to the associated seat cushion trim element 130.1.

[0056] The second three-dimensionally formed insert 132.2 can in particular be a shoulder insert (also called shoulder panel), such as a three-dimensionally formed shoulder support element, a seat back insert (also called seat back panel) and / or a neck insert (also called neck panel), such as a three-dimensionally formed neck support element. The second three-dimensionally formed insert 132.2 can be detachably or interchangeably connected to the associated seat back trim element 130.2, such as by sewing, clamping, etc.

[0057] The third three-dimensionally formed insert 132.3 can in particular be an armrest insert (also called armrest panel), such as a three-dimensionally formed armrest recess and / or a three-dimensionally formed armrest element with a holding container for utensils. The third three-dimensionally formed insert 132.3 can be detachably or exchangeably connected (e.g., sewn, clamped, etc.) to the associated seat armrest trim element 130.4.

[0058] The fourth three-dimensionally formed insert 132.4 can be in particular a headrest insert (also referred to as a headrest panel), for example a three-dimensionally formed (in particular ergonomically formed) head support. The fourth three-dimensionally formed insert 132.4 can be detachably or interchangeably connected (e.g., sewn, clamped, etc.) to the associated seat headrest trim element 130.3.

[0059] The fifth three-dimensionally formed insert 132.5 can in particular be a cover insert (also called a cover plate) for fasteners, for example a three-dimensionally formed cover strip with holes for ISO-fix fasteners. The fifth three-dimensionally formed insert 132.5 can be detachably or interchangeably connected (e.g., sewn, clamped, etc.) to an adjacent seat back trim element 130.2 and / or an adjacent seat cushion trim element 130.1.

[0060] Figure 3 Shown according to Figure 2A fifth three-dimensionally formed insert 132.5 is arranged between the backrest 104 and the seat part 102. Furthermore, a spring plate 134 can be integrally formed on the insert 132.5 or attached to the insert 132.5.

[0061] For example, the central backrest 126.2 forming the armrest can be formed in several parts. The backrest 126.2 can, for example, include a fixed backrest 104 and a seat armrest decorative element 130.4 pivotably arranged on the backrest 104. Furthermore, an armrest insert (third three-dimensionally formed insert 132.3) can be detachably or interchangeably attached to or in the seat armrest decorative element 130.4. For example, an armrest recess with a cup holder and / or a holder for an electronic device is detachably arranged on the inner side of the seat armrest decorative element 130.4 as a third three-dimensionally formed insert 132.3.
