[0030] Example 1

[0031] like Figures 1-4 As shown, a headrest for a rear seat of a car includes a pillow body and a headrest bracket. The pillow body is connected to the rear seat of the car through the headrest bracket. The pillow body includes a cover 1 covering the surface of the pillow body and a foam body 8 inside the cover 1. The cover 1 is composed of several pieces, and the pieces are connected by sewing and splicing. Eight cutting edges 4 are opened near the seam 3 of the first piece 2 and the second piece on the back of the cover 1. The cutting edges 4 are located on the first piece 2 and the inside of the cover 1.

[0032] In this embodiment, the material of the foaming body 8 is foaming polypropylene.

[0033] In this embodiment, the cutting piece is composed of a skin layer and a sponge layer, the skin layer is leather material, and the material of the sponge layer is polyurethane foam.

[0034] In this embodiment, the length of the knife edge 4 is 10mm, the interval between the knife edges 4 is 20mm, and the depth of the knife edge 4 penetrates the first cutting piece 2.

[0035] In this embodiment, the headrest support includes a support body and two vertical rods 5, the support body is arranged inside the face cover 1, the vertical rods 5 are arranged outside the face cover 1, the vertical rods 5 connect the pillow body and the rear seat of the car, the vertical rods 5 are hollow round rods, and positioning grooves 6 for adjusting the height of the pillow body are arranged on the vertical rods 5 at equal intervals, the positioning grooves 6 of the vertical rods 5 are fixed with the rear seat of the car, and the position and height of the headrest can be adjusted according to actual needs.

[0036] It should be noted that the support body is a bent pipe structure matched with the shape of the pillow body, the support body is fixedly connected with the two vertical rods 5, the support body is filled inside the face cover 1, and the foaming body 8 is filled between the face cover 1 and the support body.

[0037] As shown in Figure 4 As shown in the drawings, the first cutting piece 2 is provided with through holes 7 capable of penetrating the vertical rods 5, and the through holes 7 are two in total.

[0038] Working principle: when the utility model is assembled, first, a cutter is used to uniformly form 8 knife edges 4 with a length of 10mm on the first cutting piece 2, then the three cutting pieces are connected by sewing and splicing to form the face cover 1 with the sponge layer facing outward and the skin layer facing inward, the knife edges 4 are located near the splicing seams of the first cutting piece 2 and the second cutting piece on the back of the face cover 1, then the face cover 1 is turned from the reverse side to the front side, at this time, the knife edges 4 are located inside the face cover 1, and the headrest support is installed in the face cover 1, after the headrest support is installed, the foaming agent is filled into the face cover 1.
