As people's safety awareness increases, solutions such as making an opening on a side of the vehicle seat cover occurred. However, some of the vehicles have relatively large airbags, if the opening is relatively small, it is not easy for the airbag to pop out from the opening. Besides, the common airbag openings look unsightly on the seat cover.
Therefore, it is necessary to provide a beautiful and safe car seat cover that does not affect the ejection of the airbag.
In order to solve the problem of the prior arts, the present invention provides a vehicle seat cover comprising a cushion seat cover and a backrest cover, wherein the backrest cover comprises a front cloth, a back cloth and two side cloths, the side cloth is provided with an airbag blasting seam which is formed by hot pressing, and the airbag blasting seam is located on the side where the airbag of the vehicle seat pops out.
Preferably, the airbag blasting seam extends along the length direction of the side cloth.
Preferably, the length of the airbag blasting seam is greater than or equal to the maximum blasting diameter of the airbag.
Preferably, the vehicle seat comprises a backrest and a headrest, the backrest cover covers the backrest and headrest, and the airbag blasting seam extends from the top of the side of the backrest to the bottom.
Preferably, the backrest cover is connected to the cushion seat cover.
Preferably, the backrest cover is separated from the cushion seat cover.
Preferably, the side cloth is made of chemical fiber.
Preferably, the side cloth is made of polyester.
The present invention further provides a method of manufacturing a vehicle seat cover comprising the following steps:
cutting a front cloth, a back cloth and two side cloths to be prepared to sew a backrest cover;
hot pressing the position where the airbag of the vehicle seat corresponding to the side cloth to form an airbag blasting seam;
sewing the front cloth, the back cloth and the hot pressed side cloths into a whole to form the backrest cover;
sewing a cushion seat cover; and
connecting the backrest cover to the cushion seat cover.
The vehicle seat cover of the present disclosure comprises a cushion seat cover and a backrest cover, wherein the backrest cover comprises a front cloth, a back cloth and two side cloths, the side cloth is provided with an airbag blasting seam which is formed by hot pressing. By using hot pressing on the side cloth where the airbag of the vehicle seat pops out, the cloth is weakened. When the airbag on the side of the vehicle seat pops out, it can pop out smoothly from the weakened airbag blasting seam to protect the passenger. Meanwhile, as the airbag blasting seam formed by hot pressing does not affect the appearance of the vehicle seat cover, it ensures the beauty of the vehicle seat cover.
