[0030] FIG. 1 shows a schematic illustration of an arrangement consisting of a vehicle seat 1 according to the invention for a motor vehicle and a child seat 10 which is known from the prior art, designed in particular as an ISOFIX child seat. The vehicle seat 1 has a seat part 3 with a cushion part 50, and a backrest 5.

[0031] The seat part 3 has a load-bearing structure which comprises a fastening device 30 for fastening the child seat 10 to the vehicle seat 1. The fastening device 30 has two lower fastening elements 32 for fastening the child seat 10 which can be placed onto the vehicle seat 1. The fastening elements 32 are preferably bent steel wires which are fastened to a load-bearing structure of the vehicle seat 1, in particular the seat part 3, or to a load-bearing structure of the motor vehicle.

[0032] The child seat 10 can be fastened to the two fastening elements 32. To this end, the child seat 10 has two locking devices 12, also referred to as connectors, which project toward the rear in the lower region of the child seat 10 and can be locked to the fastening elements 32.

[0033] In addition, a further fastening means may be provided on the vehicle seat 1, to which further fastening means a safety belt 14 (also referred to as top tether), which is known from the prior art, of the child seat 10 can be fastened. The safety belt 14 is fastened in the upper region of the child seat 10, is deflected over an upper edge of the backrest 5, and is guided downward behind the backrest 5, where it can be fastened to the further fastening means of the vehicle seat 1 or the vehicle structure.

[0034] FIGS. 2 to 4 show a cushion part 50 of a seat part 3 of a vehicle seat 1 which is known from the prior art and in the present case is in the form of a rear seat. A front seat can be of analogous construction. The vehicle seat 1 has the seat part 3 and a backrest 5.

[0035] The vehicle seats 1 and the invention will be described below with the use of three spatial directions which run perpendicularly with respect to one another. In the case of a vehicle seat 1 installed in the vehicle, a longitudinal direction x runs largely horizontally and preferably parallel to a vehicle longitudinal direction which corresponds to the normal direction of travel of the vehicle. A transverse direction y which runs perpendicularly with respect to the longitudinal direction x is likewise oriented horizontally in the vehicle and runs parallel to a vehicle transverse direction. A vertical direction z runs perpendicularly with respect to the longitudinal direction x and perpendicularly with respect to the transverse direction y. In the case of a vehicle seat 1 which is installed in the vehicle, the vertical direction z runs parallel to the vehicle vertical axis.

[0036] The positional and directional specifications which are used, such as for example front, rear, top and bottom, relate to a viewing direction of an occupant seated in the vehicle seat 1 in a normal seating position, the vehicle seat 1 being installed in the vehicle and being oriented in a use position which is suitable for passenger transportation with an upright backrest 5 and, as is customary, in the direction of travel, without a child seat 10 being mounted. The vehicle seat 1 according to the invention may also be installed, however, in a differing orientation, for example transversely with respect to the direction of travel.

[0037] The seat part 3 has a seat frame which supports the cushion part 50. The cushion part 50 comprises a foam part 60. The foam part 60 is provided with the cover 70, which has a top layer, for example composed of a fabric, an artificial leather or a leather. The seat frame can preferably be connected to a vehicle structure of the vehicle.

[0038] A fastening device 30, not illustrated in FIGS. 2 to 5, for fastening the child seat 10 on the vehicle seat 1 comprises two lower fastening elements 32 for fastening a child seat 10 which can be placed on the vehicle seat 1. The fastening elements 32 are preferably bent steel wires which are connected fixedly to the vehicle structure of the vehicle, into which the vehicle seat 1 can be installed. In one modification of the exemplary embodiment, the fastening elements 32 are a constituent part of the seat frame.

[0039] The fastening elements 32 of the fastening device 30 are arranged behind a bolster 52 of the cushion part 50, which bolster adjoins the backrest 5. The cushion part 50, in the present case the bolster 52, has two through-openings 54 per seating position. The through-openings 54 are formed by way of corresponding through-holes 62 in the foam part 60, and corresponding openings 72 in the cover 70. The through-openings 54 allow locking devices 12 of the child seat 10 to be guided through the cushion part 50 and to be locked to the fastening elements 32. The fastening elements 32 may be arranged behind the associated through-opening 54 or in the associated through-opening 54.

[0040] The through-openings 54 in the cushion part 50 are concealed in each case by way of a covering 80, illustrated for example in FIG. 5, or a differently configured covering. In addition, the coverings 80 serve to respectively line the through-openings 54 in the cushion part 50. Each of the two coverings 80 has a carrier 82 and a flap 90, which is pivotably mounted on the carrier 82. When the flap 90 is in a closed state, it closes the through-opening 54 assigned to the covering 80. By pivoting the flap 90 about a pivot axis running parallel to the transverse direction y, the flap 90 opens up the through-opening 54 such that the fastening element 32 arranged behind the flap 90 is accessible.

[0041] The carrier 82 is of a frame-shaped configuration. The carrier 82 has a largely tubular basic shape with an approximately rectangular cross section. The carrier 82 is manufactured from plastic. The carrier 82 has a plurality of centering means 84 for centering the carrier 82 on the seat frame, for example in an opening of a retaining plate of the seat frame, or on a corresponding retaining plate of the vehicle structure of the vehicle. In addition, the carrier 82 has a plurality of clips 86 for fastening the carrier 82 to the seat frame, for example in an opening of a retaining plate of the seat frame, or to a corresponding retaining plate of the of the vehicle structure of the vehicle.

[0042] The carrier 82 has an edge 88 which projects outwardly around the periphery of the through-opening 54 and conceals edge regions of the cover 70 around the periphery of the opening 72.

[0043] Two exemplary embodiments of covers 100, 200 according to the invention will be described below. In comparison with the cover 70 known from the prior art, these covers 100, 200 have a design in the edge regions around the through-openings that is reinforced. The covers 100, 200 according to the invention can replace the cover 70 known from the prior art without it being necessary to make changes to further components of the cushion part 50 which is known from the prior art. In particular, the foam part 60 and the covering 80 can be combined unchanged with the covers 100, 200 according to the invention. The covers 100, 200 may consist of a plurality of cover parts which are connected to one another, preferably sewn to one another.

[0044] Unless described otherwise, the covers 100, 200 according to the invention correspond to the previously described cover 70 which is known from the prior art.

[0045] FIGS. 6 and 7 show the cover 100 of the invention according to the first exemplary embodiment. The cover 100 is a constituent part of a cushion part 50 for the vehicle seat 1 according to the invention. A foam part of the cushion part 50 is covered by the cover 100. The cover 100 may be sewn together from a plurality of cover parts.

[0046] FIG. 6 shows a view of a rear side 102 of the cover 100. The rear side 102 of the cover 100, which is also technically referred to as the B side, is that side of the cover 100 which faces a foam part. In the completely upholstered state of the cushion part 50 in the vehicle seat 1, the rear side 102 of the cover 100 is not visible to the user of the vehicle seat 1. FIG. 7 shows a view of a front side 104 of the cover 100. The front side 104 of the cover 100, which is also technically referred to as the A side, is that side of the cover 100 which faces the user of the vehicle seat 1. In the completely upholstered state of the cushion part 50 in the vehicle seat 1, the front side 104 of the cover 100 is largely visible to the user of the vehicle seat 1 and is partially in contact with the user's body.

[0047] In the present case, the cover 100 has two cover layers. A textile carrier layer 110, in particular a woven fabric, is provided with a top layer 120, in particular a vinyl layer. The carrier layer 110 and the top layer 120 are connected to one another over their surface area and constitute an artificial leather, that is to say an imitation leather. In this respect, the top layer 120 forms the front side 104 and the carrier layer 110 forms the rear side 102 of the cover 100.

[0048] In modifications of the exemplary embodiment, further cover layers, for example a knitted spacer fabric and/or a ventilation layer, may be arranged between the top layer 120 and the carrier layer 110. In further modifications of the exemplary embodiment, the top layer consists for example of a textile material or an animal skin, in particular a leather. The invention is not limited to an artificial leather cover in this respect.

[0049] The cover 100 has two openings 130. The openings 130 together with through-holes in the foam part form the through-openings of the cushion part 50. The through-openings of the cushion part 50 allow the locking devices 12 of the child seat 10 to be guided through the cushion part 50 and to be locked to fastening devices 30.

[0050] In the region of the two openings 130, the structure of the cover 100 is preferably respectively the same, if appropriate mirror-symmetrical with respect to a plane of symmetry running perpendicularly with respect to the transverse direction y, which is why only one opening 130 is described below.

[0051] An edge region of the cover 100 that delimits the opening 130 is reinforced in certain portions with a felt material 140. In the present case, the felt material 140 is sheet-like and has a U-shaped contour. The felt material 140 has a web 142 and two legs 144, 146. The web 142 and the two legs 144, 146 are integrally connected to one another, in particular felted to one another.

[0052] A lower edge region 132 in the cover 100 that delimits the opening 130 is reinforced by the web 142. The lower edge region 132 is sewn to the web 142 by a first seam 151. In addition, in the present case, the first seam 151 serves to sew a cover part of the cover 100 that has the opening 130 to a further cover part of the cover 100. The lower edge region 132 preferably runs parallel to the transverse direction y.

[0053] A first lateral edge region 134 in the cover 100 that delimits the opening 130 is reinforced by the first leg 144. The first lateral edge region 134 is sewn to the first leg 144 by a second seam 152. A second lateral edge region 136 in the cover 100 that delimits the opening 130 is reinforced by the second leg 146. The second lateral edge region 136 is sewn to the second leg 146 by a third seam 153. The two lateral edge regions 134, 136 preferably run parallel to one another and largely parallel to the vertical direction z.

[0054] In the transverse direction y, a tab 106 of the cover 100 has a width which corresponds approximately to the spacing between the first lateral edge region 134 and the second lateral edge region 136. The tab 106 is integrally connected to the rest of the cover 100 in an upper edge region 138, which delimits the opening 130. The size of the tab 106 corresponds approximately to the size of the opening 130. The tab 106 may be pivoted about the upper edge region 138.

[0055] During the mounting of a vehicle seat 1 which has the cover 100, by virtue of pushing the covering 80 into the opening 130 the tab 106 is folded over by approximately 90 degrees and arranged between the covering 80 and the foam part.

[0056] In a modification of the first exemplary embodiment, the cover 100 has a second tab, which is connected integrally to the rest of the cover 100 in the lower edge region 132. The second tab can be pivoted about the lower edge region 132 and sewn together by the first seam 151. The length of the tab 106 is preferably shorter than the above-described tab 106 by the magnitude of the length of the second tab.

[0057] FIG. 8 shows a view of a rear side 202 of the cover 200 according to the second exemplary embodiment. In the present case, the cover 200 has two cover layers. A textile carrier layer 210, in particular a woven fabric, is provided with a top layer 220, in particular a vinyl layer. The carrier layer 210 and the top layer 220 are connected to one another over their surface area and constitute an artificial leather, that is to say an imitation leather. In this respect, the top layer 220 forms the front side and the carrier layer 210 forms the rear side 202 of the cover 200.

[0058] The cover 200 has two openings 230. The openings 230 together with through-holes in the foam part form the through-openings of the cushion part 50. The through-openings of the cushion part 50 allow the locking devices 12 of a child seat 10 to be guided through the cushion part 50 and to be locked to fastening devices 30.

[0059] In the region of the two openings 230, the structure of the cover 200 is preferably respectively the same, if appropriate mirror-symmetrical with respect to a plane of symmetry running perpendicularly with respect to the transverse direction y, which is why only one opening 230 is described below.

[0060] The edge regions of the cover 200 that delimit the opening 230 are reinforced in certain portions with a felt material 240. In the present case, the felt material 240 is sheet-like and has a U-shaped contour. The felt material 240 has a web 242 and two legs 244, 246. The web 242 and the two legs 244, 246 are integrally connected to one another, in particular felted to one another.

[0061] A lower edge region 232 in the cover 200 that delimits the opening 230 is reinforced by the web 242. The lower edge region 232 is sewn to the web 242 by a first seam 251. In addition, in the present case, the first seam 251 serves to sew a cover part of the cover 200 that has the opening 230 to a further cover part of the cover 200. The lower edge region 232 preferably runs parallel to the transverse direction y.

[0062] A first lateral edge region 234 in the cover 200 that delimits the opening 230 is reinforced by the first leg 244. The first lateral edge region 234 is sewn to the first leg 244 by a second seam 252.
