The present invention relates to a disposable vinyl cover for a vehicle seat and a manufacturing method thereof, and more particularly, a disposable vinyl cover for a vehicle seat capable of covering the front of the vehicle seat while the headrest provided in the vehicle seat is stably embedded. It relates to a manufacturing method.

In general, the maintenance of the vehicle seat manufacturing process, the mounting of the vehicle in the assembly process of the finished vehicle, the painting of the interior and exterior panels of the vehicle in operation, and the healing of mechanical defects in the interior are various problems that can occur during long-term parking and stopping. One of the measures that can be provided to keep the vehicle seat clean from pollution sources is to encapsulate the entire sheet with plastic wrapping paper or attach it with a band tape in the sealed state. It can be shipped and finally delivered to consumers.

For example, the plastic sheet having a rectangular bag shape is used to cover the upper surface of the backrest portion from the top of the backrest portion to fix the sheet at the bottom of the seat, and thus is commonly used in a final assembly line for a finished vehicle of an automobile maker.

The plastic sheet for vehicle seat used in the assembly line of the finished vehicle is kept in the packing state until the shipment of the finished vehicle because it is intended to maintain the original state of the seat from the contaminants through the complete encapsulation. As the fabric, polyethylene made of polyethylene, which requires a predetermined tensile strength, is applied.

By the way, in the simple maintenance of the vehicle, it is limited by two typical problems described below and is used very rarely.

Therefore, there is a problem that the outer surface of the vehicle seat is easily contaminated due to various kinds of contaminants such as oils and paints generated during painting work, which are generated during the various simple maintenance.

In order to prevent this, a member of a paper material such as a newspaper is covered or wrapped in a temporary sheet by a temporary method, which is not only aesthetically desirable but also easily penetrates moisture, causing an adverse effect of the print on the paper. .

In addition, when encapsulating the plastic wrapper as described above, the shape of the plastic bag encapsulated to be suitable for the shape of the backrest and the seat should be maintained. In most cases, the backrest is covered with a straight bag without having such a structure. Since the wrapping paper is inclined to the front of the seat from the upper portion of the seat there is a problem that the storage and movement of the seat and seating on the seat is difficult.

On the other hand, even in a sofa for outdoor display, etc., as it is left outside for a long time, the appearance may be remarkably poor due to the surrounding dust and the smoke of the vehicle, etc., there is a problem that causes deformation of the sheet due to the inflow of moisture.
