Technical Field

The invention relates to the field of automobile seat protective surfaces, in particular to an automobile seat seamless headrest cavity protective surface structure and a manufacturing method thereof.

Background

The traditional horizontal headrest cavity protective surface of the automobile seat is limited by the traditional production process and a fixed structure, so that seamless and reverse arc modeling cannot be realized, and a sewing blind seam formed by sewing two materials together due to the fact that the protective surface needs to be tensioned can be seen on the surface of the seat, which is a result caused by the limitation of the traditional design concept and the production process. Too much problem of the molding segmentation caused by the need of tensioning limits the design space of the seat, and the requirement of a designer on appearance design cannot be met.

As shown in figure 1, seams are arranged between a core part and side wings of the existing automobile seat, and the existing automobile seat contains a reverse arc shape, a traditional horizontal headrest cavity as shown in figure 2 at least needs 4 pieces of cut pieces to be spliced and sewn to cover the headrest cavity, at least 5 sewing dividing lines need to be designed in the headrest cavity in the shape design stage of the headrest cavity, and each dividing line position needs to be tensioned by a tensioning steel wire or a tensioning belt, so that the covering of the headrest cavity is realized.

The invention changes the original surface sleeve structure, forms a brand new surface sleeve connection mode, changes the traditional tensioning and fixing surface protection mode needing sewing into a mode of utilizing the pressure sticking and fixing of the burred layer and the napped base cloth layer, and tensions and hides the seat in the skin, so that the surface of the seat has no suture. The surface tensioning effect can be embodied, the smoothness of the seat cannot be damaged due to excessive contour segmentation, the condition that the appearance of the seat is free of sewing blind seams generated by sewing two pieces of materials together is avoided, and the problem that the fabric cannot be shaped by being attached to clothes when foams have reverse arcs is effectively solved.

The existing headrest cavity is changed into an integral piece by at least 4 pieces of pieces, and only two sewing processes are carried out to beautify the appearance of the seat to the maximum extent, so that the design space of a modeler is enlarged, and the design requirement of no sewing seam on the surface of the seat can be met to the maximum extent.
