Description

One-sided semi-open reference arrangement for a motor vehicle seat, in particular sports seat

The invention relates to a reference arrangement, in particular for a motor vehicle seat with the features mentioned in the preamble of claims 1 and 11.

It is known to design covers for motor vehicle seats, which can be pulled over the base body of the motor vehicle seat after assembly of the technical components of the motor vehicle seats, such as lumbar devices, airbags, Rückenlehnenkopfverstelleinrichtungen, cheek adjustment, so that ultimately depending on the circumstances of the respective motor vehicle seat to be produced provide necessary reference arrangements on the respective body. The focus of the training of the reference arrangements are usually on the one hand, the integration and arrangement of the airbags below the reference and incorporation of predetermined breaking points in the reference and on the other the formation of a tight surface and ultimately easy installation of the covers. In particular, in sports seats, some of which have a particularly prominent contour in the cheek area, the contour-forming components are particularly important.

In principle, the cover assemblies are generally characterized in their basic construction by a seat portion and a backrest portion, each of which generally features a rigid support frame and a molded foam cushion attached thereto surrounding the support frame and a reference to the molded foam cushion.

Special solutions for covers and their arrangement for securing an effective and definitely at the right time from the reference emerging expansive airbags from the inside of a seat in the direction of the outer cover, are known from DE 198 48 905 and DE 198 48 900.

However, these documents solve only the problem of special sewing the covers in the range of side airbags on backrests and / or seat parts. The other known documents DE 36 18 057 and DE 689 16 619 but also deal with the problem of attaching the cover to a seat or backrest frame or with the possibility prefabricate a complete cover for seats and to arrange on a preformed foam cushion. Thus, DE 689 16 619 discloses a vehicle seat back cover assembly having a pair of cover parts which cooperate to form a reference cover and which are adapted to serve to receive a preformed molded foam pad encased therein. The individual coating parts are connected to each other in a special way, so that curved corners and general special contours are formed. For coating the cover on the seat assembly, a covering part thus has two parts, which are connectable to each other after covering the cover on the seat assembly with a zipper.

DE 36 18 057 describes only a possibility of attachment of a cushion cover to a seat or backrest frame. A seat or backrest frame is provided here with a reinforcement in an edge region which is formed like a flange. The U-shaped frame is engaged behind the upholstery cover and thus attached to the seat or backrest frame. In addition, it is known from this document to provide the flange-like reinforcement with additional exhibitions, preferably a profile strip is used, and to provide the cushion cover with a hook-shaped area which engages in the free edges of the exhibitions of the profile strip and thus an arrangement of the upholstery cover on the Seating or backrest frame allows.

Based on this prior art, the present invention seeks to provide a reference arrangement that is easily and accurately over the seat part and / or backrest part drawable observing the predetermined contours of a motor vehicle seat and then secure, quick and easy attachable.

The object is achieved in that one of reference parts corresponding to a contour of a preformed body of a seat part and / or a backrest part as a cover prefabricated reference einendseitig between a reference front part and a reference back a horizontal closing area and between the reference back and a reference tunnel side part or a Bezugsbag side part of a forming the horizontal closing area at most half-open unilateral vertical closing area, which is ensured according to the invention that the cover on the seat part and / or the backrest part can be pulled and closed on the horizontal and vertical closing area accurately.

The cover thus comprises at least the reference front part, at least the reference back part, at least one reference airbag side part and the reference tunnel side part. The prefabricated cover is connected to each other in accordance with the desired contour of the seat part and / or the backrest part already at most connection points between the reference parts, in particular sewn. This results in an envelope-like coating which only has the horizontal closing region in the lower region. Starting from this horizontal closing area, only one further open, vertical closing area is formed on a rear side of the cover between the reference rear part and reference tunnel side parts or reference rear part and reference airbag side part, which is necessary in addition to the horizontal closing area, to cover the raised contours of the main body of the seat part and / or to pull the backrest part. However, the vertical closing area is preferably located on a tunnel side opposite an airbag side of the motor vehicle seat, so that an opening of the airbag in the event of a crash may not lead to the opening of the vertical closing area. Of course, in principle, however, a reverse embodiment, namely that the vertical closing area is arranged on the airbag side, possible.

In a preferred embodiment of the invention, the vertical closing area and / or the horizontal closing area have closing profiles, which are preferably arranged in each case on the opposite reference part. Various conceivable profile arrangements are possible for these generally designated closing profiles of which, by way of example, a closing profile arrangement in the exemplary embodiment is described in more detail.

In addition, the reference back part in a preferred embodiment of the invention above the incipient vertical closing region single transverse seams or double transverse seams have, thus allowing only an optical subdivision of the backrest part.

Furthermore, in a preferred embodiment of the invention, the reference back part can be formed so that regardless of the vertical or horizontal closing area a pocket, as known from most motor vehicle seats in the backrest area, can be formed. In a further preferred embodiment of the invention, the bag can be formed exactly in the region of the vertical or horizontal closing region of the cover, wherein the double transverse seams for forming an elastic band can be used.

Further preferred embodiments of the invention will become apparent from the remaining, mentioned in the dependent claims characteristics. In particular to the formation of the closing profiles an exemplary arrangement is specified in the subclaims. The invention is intended However, include all conceivable closing profiles suitable for closing two opposite reference parts.

The invention will be explained in more detail in embodiments with reference to the accompanying drawings. Show it:

Figure 3 shows a perspective view of a known seat cover assembly. By way of example, a backrest 10 is shown, which is shown with a cover 100, wherein the cover 100 is in the region of a rear side 12 in the still open state. The backrest 10 has an airbag side 20 and a tunnel side 22. The airbag side 20 is formed by a reference airbag side part 120 and the tunnel side 22 by a reference tunnel side part 122. A reference front part 110 is not visible in FIG. 3, but is connected with the reference airbag side part 120 and the reference tunnel side part 122 between these parts, preferably already with the reference airbag side part 120 and the reference tunnel side part 122 in the sewn state. According to the prior art, a reference back part 112 is still shown in Figure 3a in the unfolded position. The reference back part 112 has single transverse seams 14, wherein the lower single transverse seam 14 shown as a fold 38 is connected to the upper region of the reference back part 112 and thus can be formed both as a single transverse seam 14 or as here in only as a fold 38. On the two single transverse seams 14 arranged above the fold 38, on the one hand, a lower hooking profile 34 and an upper hooking profile 36 are arranged. These hook profiles 34, 36 engage in lumbar pads 62 in the interior of the backrest 10 and thus secure the reference back 112 on the backrest 10. However, a lumbar cover 60 (FIG. 3) can be placed on the lumbar support to protect the back of the back 112. To further close the cover 100, in particular of the reference back 112 serve closing profiles 26, 28, in particular here a left vertical closing profile 26 and a right vertical closing profile 28. These closing profiles 26, 28 form an open two-sided vertical closing portion 24, which by a horizontal closing area 32 is supplemented with an arranged horizontal closing profile 30, according to Figure 3. In the prior art, as shown in FIG. 4, a right lower vertical closing profile 40 is arranged on the structure of the backrest 10. A right upper vertical closing profile 42 is stitched to the interior of the cover 100 sewn stationary and engages in the lower right vertical locking profile 40, according to Figure 5 a. This known solution shown in Figure 3a to Figure 5 is referred to as an open reference, starting from which, according to Figure 1, a semi-open reference has been further developed.

FIG. 1 shows the same components using the same reference numerals according to FIG. 3a to FIG. 5, wherein it is visible that the vertical closing area 24 and the horizontal closing area 32 with the respectively associated closing profiles 26, 28 and 32 only in the lower area through the vertical closing areas 24 extended single longitudinal seam 18 is arranged on the tunnel side. The description of FIG. 2 applies analogously to the arrangement of the vertical closing area on the airbag side 20.

This principle of the reference arrangement on a base body of a seat part and / or a backrest part is referred to as a half-open cover 10. FIG. 1 additionally shows that the reference back part 112 can be subdivided by single transverse seams 14 or by double transverse seams 16.

Starting from this prior art, FIG. 2 illustrates that for further saving of material, in particular for saving closing profiles, a prefabrication of the cover 100 is possible, in which the single longitudinal seam 18 on the Airbag side 20 is already closed to the lower edge of the cover 10 and the

Reference rear part 112 is connected to the reference airbag side part 120, in particular in

- the prefabrication has already been sewn. The necessary closing profiles according to the preceding description are thus no longer needed here and can be saved. It is also advantageous that in particular on the airbag side 20, a completely sewn cover 100 is formed, so that a triggering airbag in the

Side area of the backrest 10 does not lead to an unwanted opening of the right vertical

Closing area 24, as shown in FIG 2 may result. In principle, however, a formation of a completely sewn cover 100 is also possible on the other side, so that the vertical closing area 24 can also be formed on the airbag side. As a vertical closing region 24, the lower right region is shown by way of example as a right vertical closing region according to FIG. 2, which adjoins the single longitudinal seam 18 and thus forms a complete vertical seam after closure of the vertical closing region 24. In practice, with a vertical seam of approximately 700 mm between reference tunnel side member 122 and reference back 112 or reference back 112 and reference airbag side member (120), which includes both the single longitudinal seam 18 and the subsequent respective vertical closure region 24, a length of the vertical closure region 24 has of up to 350 mm exposed. In an embodiment for a sports seat is preferably formed a length of 280 mm for the vertical closing area.

For covering the cover 100 over the main body of the backrest 10 or a seat part is of course still the horizontal closing portion 32 with arranged horizontal closing profiles 30th

According to FIG. 1, a double transverse seam 16 is also arranged in FIG. 2, wherein an elastic band 58 can be formed between the upper and lower seams of the double transverse seam 16. The reference back portion 112 is formed from the upper seam of Doppelquernaht 16 double-layered. Between the vertical closing region 24 of the respective already already sewn seam 18 and the lower horizontal closing region 32 and the elastic is thus a pocket 56, as it is known from most motor vehicle seats, in particular their backrest can be formed.

This solution according to Figure 2, in comparison to the known solutions only a semi-open-sided reference and thus a semi-open semi-open reference arrangement.

This reference arrangement is particularly suitable for motor vehicle seats that act as sports seats are formed, in which particularly raised structures, in particular cheek areas in the backrest or in the seat part area are present.

To illustrate the closing profile arrangements, the right-hand vertical closing profile 28 in the vertical closing region 24 is discussed in connection with FIGS. 6 a, 6 b and FIGS. 7 a, 7 b. The explanations apply analogously to a left-hand vertical closing region 24 (not shown in FIG. 2).

Generally, first, the right vertical closing profile 28 is designed as a right lower vertical closing profile 40 or as a right upper vertical closing profile 42.

The right lower vertical closing profile 40 is arranged on the reference tunnel side part 122 and the right upper vertical closing profile on the reference back part 112, so that both

Closing profiles 40, 42 are arranged here fixed in terms of cover and are not arranged structurally as in the prior art according to FIGS. The profiles which are initially referred to generally as closing profiles 40, 42 are, for example, a right lower vertical one

Clamping profile 48 and a right upper vertical hook strip 50, wherein the clamping profile 48 on the reference tunnel side part 122 and the hook strip 50 on the reference back part 112 is arranged, so that for closing the cover 10 in the region of the vertical closing area

24, the hook strip 50, which is formed in accordance with FIGS. 7a and 7b, engages in the clamping profile 48, which is designed in accordance with FIGS. 6a, 6b.

Finally, after assembly, the cover 10 can be closed on the base body of the backrest part or the seat part in the horizontal closing area 32 by a generally designated horizontal closing profile 30. Analogous to the vertical closing region 24, it is shown by way of example in FIG. 2 that the right lower horizontal closing profile 44 can be a right lower horizontal clamping profile 52, according to FIGS. 6a, 6b, and the right upper horizontal closing profile 46 can be a right upper horizontal hook strip 54, according to FIG 7a, 7b can be. Again, the upper right horizontal hook strip 54 is connected to the reference back 112 and the lower right horizontal clamping profile 52 with the non-visible reference front part 110 so that the hook strip 54 can engage in the clamping profile 52, so that in turn at the vertical closing portion 24 a reversible Connection can be established. In both cases, in the case of the vertical closing area 24 as well as in the horizontal closing area 32, it goes without saying that a closing profile solution is also conceivable, in the case of the parts .DFiS-.Sphließßroftls. as the state of the art anchored structurally. However, the solution described in the AusrunrüngsDeispiei does not necessarily require structure-fixed profile parts, but the closing profiles 28, 30 are formed only fixed in terms of remuneration.
