Car seat seamless headrest cavity surface protection structure and manufacturing method thereof

Abstract

The invention discloses a seamless headrest cavity surface protection structure for an automobile seat and a manufacturing method thereof, comprising a cover assembly and a foam assembly, the cover assembly including a skin surface layer and a foam composite layer assembly, and a foam composite layer The assembly includes a brushed base cloth layer, a first foam layer, an interlining layer and an adhesive layer, the foam assembly includes a bristle strip assembly and a foam body assembly, the bristle strip assembly includes a bristle layer and a second foam layer, and the covering The leather surface is a whole piece, which is U-shaped as a whole, including the outer edge, inner edge and end edge; it can beautify the appearance to the greatest extent, and the appearance has no seams, no creases, and no wrinkles, which can satisfy the seat surface to the greatest extent. No sewing, seaming requirements.

Description

technical field [0001] The invention relates to the field of car seat cover, in particular to a seamless headrest cavity cover structure of the car seat and a manufacturing method thereof. Background technique [0002] Due to the limitations of the traditional production process and fixed structure, the traditional car seat horizontal headrest cavity cover cannot achieve seamless and anti-arc shapes. Two holes caused by the need to tighten the cover can be seen on the seat surface. This is the result of the traditional design concept and the limitation of the production process. Too many shape segmentation problems caused by the need to tighten limit the design space of the seat and cannot meet the designer's demand for appearance design. [0003] Such as figure 1 As shown, the current car seats have seams between the core and the side wings, and contain anti-arc shapes, such as figure 2 The traditional horizontal headrest cavity shown requires at least 4 pieces to be sp...

Problems solved by technology

[0002] Due to the limitations of the traditional production process and fixed structure, the traditional car seat horizontal headrest cavity cover cannot achieve seamless and anti-arc shapes. Two holes caused by the need to tighten the cover can be seen on the seat surface. The blind seam where pieces of material are stitched together is the result of traditional design concepts and production process limitations

Too many shape segmentation problems caused by the need to tighten limit the design space of the seat and cannot meet the designer's demand for appearance design

[0003] like figure 1 As shown, the current car seats have seams between the core and the side wings, and contain anti-arc shapes, such as figure 2 The traditional horizontal headrest cavity shown requires at least 4 pieces to be spliced ​​and sewn to cover the headrest cavity. At the modeling design stage of the headrest cavity, at least 5 sewing dividing lines need to be designed in the headrest cavity, and each segment The position of the line needs to be tightened with steel wires or tension belts to achieve the covering of the headrest cavity. Due to the existence of seams and anti-arc shapes, the shape space of the seat is severely limited, and the design of the seat requires no When there are seams and no folds or creases, the angle between the seat wing and the core is too large during the production process, so that the cover cannot fit with the root of the foam head, and it still cannot meet the appearance requirements
