Seat headrest structure and forming method thereof

Abstract

The invention provides a seat headrest structure and a forming method thereof. The headrest structure comprises a face sleeve and foam inside the face sleeve, wherein the face sleeve comprises a firstsurface layer and a second surface layer; the first surface layer encloses to form a three-dimensional cavity of a headrest shape; the second surface layer has the same shape as that of the first surface layer and is arranged in a cavity of the first surface layer in a matching manner; a vacant space is formed between the first surface layer and the second surface layer; the inner wall of the second surface layer encloses to form a filling space; the foam enters the filling space filled in the second surface layer from a pouring mouth; the bottom edges of the first surface layer and the second surface layer are connected to close the vacant space; and the bottom edges of the first surface layer and the second surface layer extend towards the inside of the filling space, and define and form the pouring mouth. The headrest structure provided by the invention is high in mechanization degree, good in appearance and simple in process, and can effectively save costs.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a seat headrest structure and a forming method thereof. Background technique [0002] Such as figure 1 As shown, at present, the fabric roll material used in the PIP (Pour in place) headrest cover 1 of the car seat is a composite material, and its roll structure is shown in figure 2 As shown, it is mainly composed of surface fabric 11, middle foam layer 12, and bottom film 13 (such as thermoplastic polyurethane elastomer rubber film, referred to as TPU film) through flame compounding process. [0003] For the cover structure used in PIP headrests and armrests at this stage, see image 3 As shown, first the roll material is cut into cut pieces 10, and then the cut pieces 10 are sewed up to form the face cover 1, because the roll material needs to be cut into cut pieces 10, and then all the cut pieces 10 are sewn with sewing thread 14 manually into Assembling, manpower hours...

AI Technical Summary

Problems solved by technology

[0007] In view of the above, the present invention provides a seat headrest structure and its molding method with good aesthetics, simple process, good touch and high degree of mechanization, so as to solve the problem of complex molding process of the existing headrest, high ratio of manpower to cost, and Inconsistent quality and technical problems that cannot meet customer customization requirements
