DE 10 2006 058 388 A1 discloses a method for mounting an actuating device for a vehicle, having a base part, a bezel, a handle piece and at least one Bowden cable with an end fitting, the base part having a first collar and the bezel having a second collar, a clamping gap being produced during mounting between the first collar and the second collar, and a cover being clamped in the clamping gap. The cover is pulled over the base part, the cover having a recess which lies above the chamber of the base part, and the tab of the cover being guided around the inner periphery of the first collar and being pushed by the slot onto the lug, which produces a form-fitting connection.
The invention is based on the problem of improving a cover for a vehicle seat, the cover having at least one through-opening, which can be closed by a covering. In particular, the intention is to provide the option of a high-quality configuration for an edge region of the cover that delimits the through-opening. The intention is to prevent the edge region of the cover from being able to detach from the covering in such a way that the edge region is visible. In addition, a cushion part with a corresponding cover should have a high impression of quality.
This problem is solved according to the invention by a cover for a cushion part of a vehicle seat, the cover having at least one opening, in particular in the form of a through-opening for a locking device of a child seat, an edge region of the cover that is arranged around the at least opening being reinforced at least in certain portions with a reinforcing frame.
Since an edge region of the cover that is arranged around the at least one opening is reinforced at least in certain portions with a reinforcing frame, the edge regions of the cover are prevented from being able to detach from the covering in such a way that these edge regions are visible. The cover is stiffened in the edge regions surrounding the at least one opening, as a result of which the edge regions have less of a tendency to be pulled out from under an edge of the covering in the event of high cover tension.
The reinforcing frame is produced, preferably folded, from a plastics material. The plastics material is a textile sheet material composed of an unordered fiber material which can be separated only with difficulty. The plastics material is therefore a non-woven textile. The material thickness of the plastics material is for example in a range of between 1 mm and 5 mm, preferably approximately 3 mm.
The subclaims relate to advantageous embodiments, which may be used individually or in combination with one another.
The reinforcing frame may be arranged on a rear side of the cover.
The reinforcing frame may have a U-shaped form. The reinforcing frame may have a web and two legs. The web may be connected to at least one of the two legs by at least one hinge. The hinge may be in the form of a film hinge.
The reinforcing frame may be folded from a plastics material with a material thickness of between 1 mm and 5 mm, preferably between 2 mm and 4 mm. A depth of the reinforcing frame may be at least three times greater, preferably at least ten times greater, than the material thickness of the plastics material.
The reinforcing frame may be sewn to the cover by at least one seam. The cover may have at least one tab in at least one edge region adjoining the opening. The at least one tab may be turned over in the direction of a rear side of the cover and may be sewn to the cover (100) and/or to the reinforcing frame. The reinforcing frame may have been pressed into the opening, in particular folded into the opening.
The problem is also solved by a cushion part for a vehicle seat, in particular a motor vehicle seat, having a cover according to the invention. A cushion part with a cover according to the invention has a high impression of quality.
The problem is also solved by a vehicle seat with at least one such cushion part.
A covering, which is pushed through the opening in the cover, preferably has an edge. The edge preferably conceals that region of the front side of the cover which is reinforced by the plastics material on the rear side of the cover, such that regions of the front side of the cover in which the reinforcing frame could cause impressions in a top layer of the cover and/or seams by way of which the plastics material is sewn to the cover are not visible.
The invention is explained in more detail below on the basis of two vehicle seats, which are illustrated in
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.
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.
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.
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.
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.
The seat part 3 has a seat frame which supports the cushion part 50. The cushion part 50 comprises a foam part 60 and a cover 70. 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.
A fastening device, not illustrated in
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. 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 respectively associated through-opening 54 or in the respectively associated through-opening 54.
The through-openings 54 in the cushion part 50 are concealed in each case by way of a covering 80, illustrated for example in
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.
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.
Unless described otherwise, the cover 100 according to the invention corresponds to the previously described cover 70 which is known from the prior art.
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.
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.
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. The through-openings of the cushion part 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.
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.
An edge region of the cover 100 that delimits the opening 130 is reinforced in certain portions with the reinforcing frame 140, which is composed of plastics material. The plastics material 140 is folded from a flat sheet blank 142 to form the reinforcing frame 140. The reinforcing frame 140 has a U-shaped contour. The reinforcing frame 140 has a web 144 and two legs 146, 148. The web 144 and the two legs 146, 148 are respectively largely perpendicular with respect to the rear side 102 of the cover 100.
The web 144 is connected to the two legs 146, 148 by way of a flexible hinge 150 in each case. In the present case, the hinge 150 is formed by two notches 152 and a film hinge 154 (a flexible, thin-walled joint channel) in the plastics material.
The depth of the web 144, measured parallel to the longitudinal direction x, is greater than the material thickness of the plastics material. The depth of the web 144, measured parallel to the longitudinal direction x, is at least three times greater, preferably at least ten times greater, than the material thickness of the plastics material. The depth of the two legs 146, 148, measured parallel to the longitudinal direction x, is greater than the material thickness of the plastics material in each case. The depth of the two legs 146, 148, measured parallel to the longitudinal direction x, is at least three times greater, preferably at least ten times greater, than the material thickness of the plastics material in each case.
