Description

The invention relates to an adjustable vehicle seat with a seat part and a relative to the seat part adjustable backrest, which can be folded or pivoted forward from an upright position of use, in particular in a functional position, for. As an easy entry position with partially folded backrest or a cargo position or table position.

The seat part and the backrest generally have a padding with covers, which are mounted on a seat frame, wherein the seat frame also forms an adjustment kinematics of the folding movement of the backrest.

When folding the backrest, however, part of the side of the backrest or between the backrest and seat part forms a side gap in part, which allows insight into the seat frame behind the upholstery of the backrest and jamming in this area.

To cover columns of an adjustable vehicle seat covers are generally known.

The DE 10 2004 056 431 B4 describes a vehicle seat with a seat part and a folding forward on the seat part backrest. A backrest cushion has a cushion middle part and a side cushion part, which can be pivoted relative to the cushion middle part, which is pivoted inwardly when the backrest is folded in through side panels.

The US 6572192 B2 shows an adjustable vehicle seat, in which a flap is provided for covering in a front region of the seat cushion.

The invention has for its object to provide an adjustable vehicle seat, which allows a high level of security and a good aesthetic impression with high stability in the different positions. Furthermore, a method for its production is provided.

This object is achieved by a vehicle seat according to claim 1. The dependent claims describe preferred embodiments.

Thus, an adjustable side gap cover is attached to the backrest cover or as part of the backrest cover covering a side gap in the lower lateral region of the backrest when folding the backrest. The side gap cover is preferably attached laterally as an additional component and in the lateral direction, d. H. from the side, attached, in particular screwed.

Side-gap covers according to the invention can be mounted or screwed on both sides of the backrest, i. on the door side (outward-facing side) and on the tunnel side (side facing the interior). Here, the side gap covers in particular on the back frame, in particular the side back frame profiles, are screwed.

The side-gap cover is preferably formed with a pocket which receives a stabilizer with a higher rigidity than the pocket, the stabilizer again being preferably formed by a z. B. plastic formed fixing element and a spring device, in particular a spring steel or spring wire. The spring steel can thus determine the outer shape of the side gap cover, z. B. as a closed loop, and is added to the fixing in the bag.

The bag can be sewn to another part of the backrest cover, the z. B. covers a side cushion.

The side gap cover is fixed to the back frame, to which it advantageously has a hole for passing a screw, and covers the gap in the lower lateral area, which serves for belt connection according to the Isofix system. When folding the backrest, the gap cover can thus fold against the spring action of their spring to the rear.

Thus, can be achieved with a wrinkle-free connection while avoiding wrinkles in the back cover during Einklappvorgang by the additional component of the side gap cover.

Compared to covers which are sewn to the backrest cover in a large-area connection seam, the assembly process is also significantly simplified:
Thus, the bag can be formed by folding and sewing a textile blank with a Fixiernaht to form an opening for later insertion of the stabilizer and z. B. are sewn to a part of the backrest cover over a tether; This can already be done in the formation of the backrest cover by a tethered as a process step, a retaining band, which is sewn in accordance with the bag.

The stabilizer formed from the fixing element and the spring element can then be inserted into the pocket, and subsequently the side gap cover can be screwed to the back frame.

Thus, a safe and procedurally simple training and continue also attachment of the side gap cover allows, in particular by sewing operations and a screwing.

By introducing the stabilizer into the inwardly-facing opening after the sewing process, it does not hinder the sewing process by its rigidity, which is particularly advantageous in this region of the backrest cover, which is difficult to access or difficult to position on a sewing machine.

By forming a spring action in the side gap cover itself, a deformation of the backrest cover can be avoided; the side gap cover is attached via the screw or other form-fitting attachment directly to the backrest frame and can swing in when folding the backrest to the rear, under tension of the spring, without a deformation of the backrest cover and wrinkles, etc.

By tilting the side gap cover to the rear when the backrest folds forward, the side gap can be safely covered. In this case, the pivoting process preferably takes place against the action of the spring element, which thus relaxes when pivoting back.

To avoid a disadvantageous Vorschwenken the side gap cover to the front, is advantageously a holding means, for. As a tether, attached to the side gap cover, in particular the bag, which in turn positioned behind the bag and fixed, z. B. can be sewn. This ensures that the side gap cover pivots inwards and backwards.

• – Ausbilden einer Tasche durch Umlegen eines Zuschnittes und Fixieren des umgelegten Zuschnittes durch eine Fixiernaht, unter Ausbilden einer Öffnung, und Fixieren eines Haltemittels und Vernähen der Tasche mit mindestens einem weiteren Lehnenbezug-Teil in einer Schließnaht und Befestigen des Haltemittels zur Begrenzung einer Verstellbarkeit der Seitenspaltabdeckung relativ zu dem Lehnenbezug,

• – Aufziehen des Lehnenbezuges mit der Seitenspaltabdeckung auf die Rückenlehne vor oder nach Einsetzen des Stabilisators,
• – Befestigen der Seitenspaltabdeckung an einem seitlichen Bereich der Rückenlehne.

Thus, the vehicle seat can be produced by a method with at least the following steps:

• - Forming a bag by folding a blank and fixing the folded blank by a fixing seam, forming an opening, and fixing a holding means and sewing the bag with at least one other backrest cover part in a closing seam and attaching the holding means for limiting an adjustability of the side gap cover relative to the backrest cover,
• Inserting a stabilizer into the pocket, whereby the side gap cover is formed,
• - mounting the backrest cover with the side gap cover on the backrest before or after inserting the stabilizer,
• - Attach the side gap cover to a side portion of the backrest.

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

1 a vehicle seat in sitting position with substantially upright back, according to an embodiment of the invention;

2 a detailed view of the vehicle seat 1 in the left transition area between back and seat part;

3 the seat off 1 during pivoting of the back in a functional position;

4a) Side views of the two side gap covers;
b) a front view of a side gap cover; and

5 a detailed description of the stabilizer.

A vehicle seat 1 has a seat part 2 and a backrest 3 up in the sitting position of the 1 is essentially upright and according to 3 forward on the seat part 2 can be folded forward or swiveled in order to achieve a functional position, for. B. a cargo position or table position with substantially horizontally vorklappter backrest 3 , or an easy entry position with partially folded backrest 3 ,

The backrest 3 has a cushion middle part 5 and side cushions 7 . 8th on, the z. B. lateral areas of a U-shaped area can be. On this upholstery in a backrest cover 6 mounted, which is generally formed by individual backrest cover parts. So is on the side pads 7 and 8th one backrest cover each 7a . 8a provided, preferably with other backrest cover parts of the backrest cover 6 sewn.

The individual structural parts of the vehicle seat 1 ie the seat frame 9 , is in 1 largely concealed and in the partially folded position of the 3 partially recognizable. The seat part 2 has z. B. Seat frame side profiles 10 . 11 and inner seat frame parts 27 , z. B. inner panels 27 on, which extend substantially in the longitudinal direction. The backrest 5 has accordingly indicated backrest side profiles 12 . 14 on, which can be hidden or lying outside.

In the lower side areas of the backrest 3 are each side gap covers 18 provided, ie a door-side, the tunnel-side side gap cover 18 ,

The side gap cover 18 serves to cover one laterally behind the side pad 7 when folding in forming side gap 25 that gives a glimpse behind the upholstery of the backrest 3 , ie in particular behind the side cushion 7 on the seat frame 9 would allow. Through the side gap cover 18 Thus, the accidental intrusion of objects, and possibly a violation of the hand of a user in the side gap 25 prevented.

The side gap 25 can vary depending on the specific design of the seat frame 9 train in different ways. In the embodiment shown, it occurs between the inner panel 27 and the side pad 7 (and on the other side according to the side cushion 8th ), as they adjust relative to each other in Vorschwenken, ie the side pad 7 pivots on the inner panel 27 ,

The side gap cover 18 allows this folding or pivoting movement and covers the forming side gap 25 off by when folding the backrest 3 through the inner panel 27 is pivoted inwards and outwards.

The side gap cover 18 comes with the backrest cover part 7a in a closing seam 21 sewed and thus looks visually not disturbing, but harmonious as part of the side pad 7 , Furthermore, this ensures a high stability of this training. Outward is only the front of the bag 20 but not the opening formed at the back.

The side gap cover 18 each has a stabilizer 19 which by a z. B. formed as a plastic part fixing 29 and a spring wire 30 is formed, and a bag 20 on, which has the opening into which the stabilizer 19 can be inserted. Thus, the z. B. bent as a loop spring wire 30 in insertion holes of the fixing 29 be plugged so that the outer shape of the stabilizer 19 is fixed, and this stabilizer 19 in the bag below 20 be used.

To attach a screw through a hole 31 the side gap cover 18 set and in the lateral direction in the respective backrest frame 12 or 14 screwed.

When folding the backrest 5 becomes the side gap cover 18 swung away to the rear, under tension of the spring wire 30 , The backrest cover 6 or the backrest cover parts 7a . 8a are not claimed in this pivoting process.

For the production of the side gap cover 18 will the bag 20 by folding a blank through the closing seam 21 sewn so that the opening remains open. Through a fixing seam 23 - or another seam - will continue to be a tether 22 to the bag 20 sewn. In 4 are two fixation seams 23a . 23b shown.

The closing seam 21 is preferably with greater stitch depth and needle size, z. B. 8mm, formed as the Fixiernaht 23 that z. B. is formed with a stitch depth of 3 mm.

The tether 22 is positioned so that it protrudes to the rear and there by a seam, z. B. the closing seam 21 or another reference seam is attached. This will be an adjustment of the bag 20 and thus the entire side gap cover 18 limited to the front; There will be an adjustment in the pivoting movement of the backrest 5 and also by improper handling of a user, in which the side gap cover 18 bent or swung forwards prevented.

The stabilizer 19 would in case of premature insertion in the bag 20 the sewing process of the closing seam 21 prevent and is therefore only finally inserted through the opening when the closing seam 21 already trained.

• – zunächst die Tasche 20 durch Umlegen eines Zuschnittes und Fixieren durch eine Fixiernaht 23, unter Einbeziehung des Haltebandes 22 ausgebildet,
• – der Stabilisator 19 ausgebildet, indem der Federdraht 30 in das Fixierelement 29 gesetzt wird,
• – der Stabilisator 19 vorzugsweise bereits in die Tasche 20 gesetzt, so dass die Seitenspaltabdeckung 18 bereits fertiggestellt ist,
• – der gesamte Lehnenbezug mitsamt Seitenspaltabdeckung 18 auf die Rückenlehne 3 aufgezogen.
• – vor oder nach dem Aufziehen des Lehnebezugs die jeweilige Seitenspaltabdeckung 18 an der Rückenlehne 3 befestigt, indem in seitlicher Richtung durch das jeweilige Befestigungsloch eine Schraube gesetzt und im Lehnenrahmen verankert wird.

For training and installation of the side gap cover and thus manufacture of the vehicle seat 1 becomes so

• - first the bag 20 by folding a blank and fixing by a Fixiernaht 23 , including the tether 22 educated,
• - the stabilizer 19 formed by the spring wire 30 in the fixing element 29 is set,
• - the stabilizer 19 preferably already in the bag 20 set, leaving the side gap cover 18 already finished,
• - The entire backrest cover including side gap cover 18 on the backrest 3 reared.
• - Before or after putting on the Lehnbeszugs the respective side gap cover 18 on the backrest 3 fastened by a screw is placed in the lateral direction through the respective mounting hole and anchored in the back frame.
