Description

[0001] The invention relates to a cover for an upholstered part of a vehicle seat. State of the art

[0002] Current technology uses various fastening devices, such as zippers, to secure and tension seat covers. Fasteners typically enable a detachable connection between cover materials or between the cover and the cushion support. Zippers typically require additional installation space, precise alignment, and significant assembly effort. Furthermore, their use in highly contoured areas, such as seat belt buckle openings or tight radii, is limited.

[0003] Seat covers that are stretched over a piece of upholstery are known from the state of the art. Task

[0004] The object of the present invention is to provide a cover, in particular a seat cover, which is improved compared to the prior art and which is designed to be material-saving, space-saving, easy to assemble and tensionable in order to enable a wrinkle-free adaptation of the cover to an upholstery part and upholstery structures. Solution

[0005] The object is achieved according to the invention by a cover having the features of claim 1.

[0006] Advantageous embodiments of the invention are the subject of the subclaims.

[0007] The cover according to the invention comprises at least two complementary fastening elements, wherein two opposing cover sections are designed as fastening elements, each formed from a textile material of the cover, or two separate fastening elements cut from a textile material are provided on these cover sections. A first fastening element is provided with a slit-shaped cutout, and a second fastening element has a hook-shaped or arrow-shaped end region. When the fastening elements are connected, the hook-shaped or arrow-shaped end region of the second fastening element is guided through the slit-shaped cutout of the first fastening element and engages behind it.

[0008] In certain areas, such as around seat belt buckle openings, Isofix recesses, and / or pronounced seat contours, targeted tensioning is required to prevent wrinkles and ensure a precise fit of the cover to the upholstery geometry. Therefore, there is a need for simple, material-saving, and easy-to-install covers with fastening solutions that simultaneously enable a secure and tensionable cover connection.

[0009] The advantages achieved by the invention are, in particular, that by means of the closure elements and their connection method, for example a combined plug connection and snap connection, a crease-free adjustment of the cover with sufficient tensioning force is possible.

[0010] The locking elements have comparatively little wear.

[0011] At the same time, the locking elements can be connected and separated without additional mechanical components and tools.

[0012] Because the fastening elements are made of a textile material, they can be easily attached to a cover, for example, by sewing. The fastening elements of the fastening device can each be connected to the cover element by at least one seam.

[0013] Alternatively, the cover and fasteners can be formed as a single piece. The cover can be prefabricated with integrated fasteners as a single cut-to-size piece.

[0014] The cover can be formed, for example cut, from a thermally pretreated felt material and / or thermally pretreated nonwoven material.

[0015] The closure elements can be cut-to-size pieces from a thermally pretreated felt material and / or thermally pretreated nonwoven material. For example, the closure elements can be thermally bonded cut-to-size pieces. The closure elements, cut from textile material and particularly flat in design, require very little installation space.

[0016] Through thermal pretreatment, in particular thermal hardening, the closure elements can have a certain strength and / or rigidity.

[0017] At least the hook-shaped or arrow-shaped end region of the second closure element can be elastically deformable and / or flexible. The hook-shaped or arrow-shaped end region, for example in the form of a projection, can be briefly deformed when passed through the slot-shaped cutout and then return to its original shape in order to lock, in particular wedge, into the slot-shaped cutout in a form-fitting and force-fitting manner.

[0018] The closure elements can be designed to taper conically in the insertion direction.

[0019] The hook-shaped or arrow-shaped end region can protrude axially from a closure body of the second closure element. The end region can be designed in the form of a hook-shaped or arrow-shaped projection. The hook-shaped or arrow-shaped end region can be spaced from the closure body, so that an exposed recess is formed between the closure body and the hook-shaped or arrow-shaped end region. The recess allows an integrated retaining contour to be easily formed.

[0020] The hook-shaped or arrow-shaped end region of the second closure element can have at least one retaining contour to prevent accidental detachment from the first closure element. The retaining contour can engage behind the slot-shaped cutout, counter to the insertion direction. The retaining force can be increased by a press fit of the hook-shaped or arrow-shaped end region through the slot-shaped cutout.

[0021] After passing through the cutout, the retaining contour can act as a “stopper” that prevents backward movement.

[0022] Under the application of force, the hook-shaped or arrow-shaped end region of the second fastening element can be released from the first fastening element for repeatable assembly and disassembly of the cover.

[0023] The slot-shaped cutout of the first closure element is rectangular or oval and a width of the slot-shaped cutout is smaller than a maximum width of the hook-shaped or arrow-shaped end region of the second closure element.

[0024] The slot-shaped cutout of the first closure element can be arranged transversely to the longitudinal extent of the first closure element.

[0025] The slot-shaped cutout of the first closure element can be arranged centered in the transverse direction of extension in the first closure element.

[0026] A cushioned part of a vehicle seat can have at least one opening, for example a belt opening and / or an Isofix recess. The cover according to the invention can be stretched over the cushioned part. Figures and embodiments of the invention

[0027] Embodiments of the invention are explained in more detail with reference to the drawings. In the drawings: Fig. 1 schematically shows a vehicle seat provided with a cover, comprising at least a seat part and a backrest, Fig. 2 schematically shows a closure device according to the invention for a cover, in particular a seat cover, wherein the closure device comprises two closure elements, Fig. 3 schematically shows a rear view of a cover lying against an upholstery part with a closure device, wherein closure elements of the closure device are detachably connected to one another, and Fig. 4 schematically shows in rear view the cover attached to an upholstered part with the closure device according to Fig. 3, wherein the closure elements are separated from each other.

[0028] Corresponding parts are provided with the same reference numerals in all figures.

[0029] Fig. 1 schematically shows a vehicle seat 100 provided with a cover 200, comprising at least one seat part 102 and a backrest 104.

[0030] The backrest 104 can be pivotally mounted on a seat part 102 of the vehicle seat 100. For this purpose, the vehicle seat 100 can optionally include a fitting 106.

[0031] The vehicle seat 100 can optionally include a longitudinal adjustment device 110. The longitudinal adjustment device 110 comprises, for example, a rail arrangement 112 with a first rail element 114 and a second rail element 116. The first rail element 114 is adjustable relative to the second rail element 116.

[0032] A cover 200, also called a seat cover or seat lining, is stretched over a cushioned part 202 of the seat part 102. Another cover 200 can be stretched over a cushioned part 204 of the backrest 104.

[0033] To allow the cover 200 to be easily stretched and secured over the respective upholstery part 202, 204, the cover 200 is provided with a closure device 210 according to the invention. The closure device 210 can be positioned, for example, on an underside 102.1 of the seat part 102.

[0034] Fig. 2 schematically shows a closure device 210 according to the invention for a cover 200, in particular a seat cover, wherein the closure device 210 comprises two closure elements 220, 230.

[0035] The closure elements 220, 230 are each cut from a textile material 300. The textile material 300 can be, for example, a felt material and / or a nonwoven material. The textile material 300 is, in particular, thermally pretreated, in particular consolidated. The textile material 300 is, for example, a so-called "thermofelt" ("thermofelt"). For example, the closure elements 220, 230 are cut pieces 222, 232.

[0036] Because the closure elements 220, 230 are formed from a textile material 300, they can be easily connected to the cover 200, for example by sewing.

[0037] Through thermal pretreatment, in particular thermal bonding, of the closure elements 220, 230, they can exhibit a certain strength and / or rigidity. The textile material 300 enables the formation of at least partially flexible and / or elastically deformable closure elements 220, 230.

[0038] A first closure element 220 is provided with a slot-shaped cutout 224. A second closure element 230 has a hook-shaped or arrow-shaped end region 234, wherein in a connected state 240 (in Fig. 3) of the closure elements 220, 230, the hook-shaped or arrow-shaped end region 234 of the second closure element 230 is guided through the slot-shaped cutout 224 of the first closure element 220 and engages behind it. In the illustrated embodiment, an arrow-shaped end region 234 is shown and will be further developed as such below.

[0039] The advantages achieved by the invention are, in particular, that by means of the closure elements 220, 230 and their connection method, for example a combined plug connection and snap connection or wedge connection, a crease-free adjustment of the cover 200 with sufficient tensioning force is possible.

[0040] At least the arrow-shaped end region 234 of the second closure element 230 can be elastically deformable and / or flexible. The second closure element 230 has, in particular, a tapered end region 234. The arrow-shaped end region 234 can simplify passage through the cutout 224.

[0041] The arrow-shaped end region 234, for example in the form of a projection, can be deformed briefly when passing through the slot-shaped cutout 224 and then return to its original shape in order to lock, in particular wedge, into the slot-shaped cutout 224 “on the back” in a form-fitting and force-fitting manner.

[0042] The closure elements 220, 230 can be designed to taper conically in the insertion direction 250.

[0043] The arrow-shaped end region 234 protrudes axially from a closure body 236 of the second closure element 230. The arrow-shaped end region 234 is spaced apart from the closure body 236 in sections, so that an exposed recess 238 is formed between the closure body 236 and the arrow-shaped end region 234. The recess 238 allows an integrated retaining contour 234.2 to be easily formed.

[0044] The arrow-shaped end region 234 of the second closure element 230 has at least one retaining contour 234.2 to prevent accidental detachment from the first closure element 220. The retaining contour 234.2 can engage behind the slot-shaped cutout 224 counter to the insertion direction 250. Under the application of force, the arrow-shaped end region 234 of the second closure element 230 can be released from the first closure element 220 for repeatable assembly and disassembly of the cover 200.

[0045] The arrow-shaped end region 234 has a tapered arrowhead 234.1 and, opposite (on the rear side), the retaining contour 234.2. The retaining contour 234.2 is formed by the arrow geometry. The retaining contour 234.2 can also be provided with locking elements, such as locking lugs. A tapered shaft section 236.1 can extend between the retaining contour 234.2 and the closure body 236.

[0046] The slot-shaped cutout 224 of the first closure element 220 can be rectangular or oval. The slot-shaped cutout 224 has a width b1 that is smaller than a maximum width b2 of the arrow-shaped end region 234, in particular the retaining contour 234.2, of the second closure element 230.

[0047] The slot-shaped cutout 224 of the first closure element 220 can be arranged transversely to the longitudinal extension direction x of the first closure element 220.

[0048] The slot-shaped cutout 224 of the first closure element 220 can be arranged centered in the transverse direction y in the first closure element 220.

[0049] Fig. 3 shows a schematic rear view of a cover 200 resting against a cushion part 202, 204 with a closure device 210, wherein closure elements 220, 230 of the closure device 210 are detachably connected to one another.

[0050] In certain areas, for example in the vicinity of openings 120, such as belt buckle openings, Iso-Fix recesses and / or pronounced seat contours, targeted tensioning is required to prevent the formation of wrinkles and to ensure a precise adaptation of the cover 200 to an upholstery geometry.

[0051] The cover 200 comprises complementary closure elements 220, 230 on two opposing cover sections 200.1, 200.2. The cover 200 itself can be formed from a textile material 300. The closure elements 220, 230 can be formed from the same textile material 300 as the cover 200.

[0052] Fig. Fig. 4 shows schematically in rear view the cover 200 resting on a cushion part 202, 204 with the closure device 210 according to Fig. 3, wherein the closure elements 220, 230 are separated from each other.

[0053] The closure elements 220, 230 formed from textile material 300, in particular felt material and / or nonwoven material, have comparatively low wear.

[0054] The closure elements 220, 230 can be releasably connected to one another without additional mechanical components and tools.
