Description

Anti-twisting structure for sewing head of seat surface

Technical Field

The utility model relates to a car seat technical field, in particular to seat face cover seam prevents turning round structure.

Background

The four-six seat divides the rear row of seats into a large seat and a small seat according to the four-six proportion, so that two backrests of the four-six seat can be respectively put forwards to be communicated with a back compartment, and people can sit on the seat while goods are loaded. At present, all cushion and backrest with a quarter-quarter structure have the problems of large gap, uneven height and non-uniformity of quarter splicing seams, so that sewing fabric of a face cover is exposed, and the appearance and the comfort are influenced; the main reason for the problems is that the sewing head of the face cover sewing does not fall to one side during assembly, staff need to shape during assembly, the contour consistency of the face cover is difficult to ensure, and the sewing head is easy to twist left and right and is not controlled; just because the surface cover contour is inconsistent, the surface cover of the quarter seat and the surface cover of the sixth seat are difficult to be spliced together tightly and smoothly. Except for the four-six seat, the surface cover of almost all seats has the problem that the seam head is twisted left and right, and the contour of the surface cover is difficult to keep consistent.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the above-mentioned prior art, the utility model aims at providing a seat face cover seam head prevents distorting structure to the seam head of solving current seat face cover twists about easily, the face cover profile is difficult to keep unanimous problem.

In order to realize the above-mentioned purpose, the utility model provides a seat face cover seam head anti-twist structure, including two adjacent surface fabrics of seat face cover concatenation department, be first surface fabric and second surface fabric respectively, first surface fabric and second surface fabric are sewed up and are formed the seam head together, and laid thickness for 1 ~ 4mm along the stylolite of two surface fabrics in the inboard of second surface fabric to with the unanimous inner liner of seam head length, the inner liner is sewed up along the seam head with first surface fabric together with the thickness that increases the seam head, the both ends end of inner liner forms the guide segment with second surface fabric stitching, and two guide segments link to each other with the both ends of seam head respectively and form "U" shape seam line, when seat face cover suit is on the seat foam, the inner liner is pressed between seat foam and seat face cover, stitches the head under the direction of guide segment and falls to one side of second surface fabric automatically.

In the scheme, the method comprises the following steps: the inner lining layer is made of thin flannelette or thin felt.

In the scheme, the method comprises the following steps: the width of the inner liner layer is 25-60 mm, the width of the cloth is not too large, and the too large width is easy to generate a large-range bulge on the seat cover, so that the hand feeling of the seat cover is influenced.

In the scheme, the method comprises the following steps: the length of the guide section is 1/2-2/3 of the width of the lining layer, and the guide section can better play a role in guiding in the range.

In the scheme, the method comprises the following steps: the width of the inner liner is 50mm, which is the optimum choice for most seats.

In the scheme, the method comprises the following steps: the sewing head and the guide section are integrally sewn, the sewing head and the guide section are sewn at one time, and the operation is convenient and quick.

The utility model has the advantages that: through the position department of sewing up at first surface fabric and second surface fabric add the inner liner and sew up together in order to increase the thickness of sewing up the head, it is difficult to the distortion after the increase of sewing up head thickness, when overturning to laminating with the seat foam by opening the form with the second surface fabric, the inner liner presses between seat foam and seat face cover, sew up the head under the direction of guide section and can fall to the one side of second surface fabric automatically, the distortion about sewing up the head has effectively been prevented, the uniformity of seat face cover profile has been guaranteed, and then also make adjacent two seats (for example quartering seat and sextant seat) can be inseparable, splice together smoothly.

Drawings

Fig. 2 is a schematic view of a first fabric and a second fabric sleeved on seat foam.

Detailed Description

As shown in fig. 1-2, a seat cover seam head anti-twisting structure comprises two adjacent fabrics at the splicing position of a seat cover, namely a first fabric 1 and a second fabric 2, wherein the first fabric 1 and the second fabric 2 are sewn together to form a seam head 4.

The inner lining layer 3 with the thickness of 1-4 mm and the length consistent with that of the sewing head 4 is arranged on the inner side of the second fabric 2 along the sewing lines of the two fabrics, the inner lining layer 3 and the first fabric 1 are sewn together along the sewing head 4 to increase the thickness of the sewing head 4, and the sewing head 4 is not easy to twist after the thickness is increased.

The ends of the two ends of the lining layer 3 and the second fabric 2 are sewed to form guide sections 41, and the two guide sections 41 are respectively connected with the two ends of the sewing head 4 to form a U-shaped sewing line.

When the seat surface sleeve is sleeved on the seat foam 5, the inner liner 3 is pressed between the seat foam 5 and the seat surface sleeve, and the sewing head 4 automatically falls to one side of the second fabric 2 under the guidance of the guide section 41.

Preferably, the inner liner 3 is made of a thin flannel or a thin felt.

Preferably, the width of the lining layer 3 is 25-60 mm, the width of the cloth 3 is not too large, and the too large width is easy to generate a large-range bulge on the seat cover to influence the hand feeling of the seat cover.

Preferably, the length of the guide section 41 is 1/2 to 2/3 of the width of the inner liner 3, and the guide section 41 can preferably perform a guiding function in this range.

Preferably, the width of the inner liner 3 is 50mm, which is the optimum choice for most seats.

Preferably, the sewing head 4 and the guide section 41 are integrally sewn, and the sewing head 4 and the guide section 41 are sewn at one time, so that the operation is convenient and quick.
