Description

Fixing structure at bottom of concave headrest cavity surface sleeve

Technical Field

The utility model belongs to the technical field of car seat, concretely relates to fixed knot of concave type headrest cavity face cover bottom constructs.

Background

With the continuous progress of the automobile industry, the shape of the headrest cavity of the automobile seat backrest is concave, for example: the public is in the ambit of three rows of backrests and Biyadhan. The concave cavity often causes the bottom and the vertical surface cut pieces to be wrinkled due to insufficient fixing points and operation space, and the appearance is affected. The following structures are more common:

1. and sewing a plastic sheet with an external shear port at the bottom of the headrest cavity, and then inserting the external shear port of the plastic sheet into the foam on the vertical surface of the headrest cavity of the backrest during assembly. However, there are many risks and difficulties associated with this operation. Risk: because the plastic sheet has an acute angle, hands of sewing and assembling operators are easily scratched, and potential safety hazards are brought to production. Difficulty is as follows: in the sewing position, the plastic sheet needs to be accurately sewn on the surface sleeve, so that the operation is very difficult, and the quality problem is easily caused.

2. The vertical surface of the headrest cavity is provided with a groove, the inside of the foam is provided with a nylon hasp, and the surface sleeve is provided with a sewing burr strip. During assembly, a bonding mode is adopted. This method is difficult to assemble and shape and has poor appearance quality. In addition, the barbed strips are adhered to the foam hasps, so that the adhesive force is not strong and the barbed strips are easy to separate.

The prior art discloses an installation locating plate mechanism of a headrest of a rear seat of an automobile, which adopts a mode that a plastic sheet is sewn on a face sleeve at the bottom of the headrest and then the plastic sheet is inserted into foam, so that acute-angle sharp points appear on the face sleeve.
