Abstract

One object of the present invention is to provide a vehicle seat covering system that results in a vehicle seat having a good appearance and a simple mechanism, wherein a seat-cover assembly evenly covers the seat-pad assembly on the side parts of the seat, closely fitting the shape of the seat-pad assembly

The present invention is a vehicle seat covering system, wherein a seat-pad assembly is covered with a seat-cover assembly whose main part and side parts are sewn along the boundaries of the main part and side parts. The vehicle seat covering system is equipped with (a) side-part pulling tubes that have a shape of a long tube and that are sewn onto the boundaries between the main part and the side parts, and (b) pulling parts that have a u-shape or somewhat circular shape and that penetrate the side-part pulling tubes in the longitudinal direction thereof, and one end or both ends of which is/are pulled to the side of the seat-pad assembly in its longitudinal direction.

Claims

1. A vehicle seat covering system, wherein a seat-pad assembly is covered with a seat-cover assembly whose side parts and main part are sewn together along their boundaries, with the seat covering system.

(a) side-part pulling tubes that have the form of a long tube along the longitudinal direction of the boundaries between the side parts and the main part, and that are sewn onto the main part and side parts along the boundaries, and

(b) pulling parts that have a u-shape or somewhat circular shape and that penetrate the side-part pulling tubes along the longitudinal direction thereof, and one end or both ends of which is/are pulled to the side(s) of the seat-pad assembly in its longitudinal direction.

2. A vehicle seat covering system as described in claim 1, characterized such that sewn parts for sewing the boundaries between the side parts and the main part are pulled in such a way that the sewn parts can be positioned inside a pulling groove of the seat-pad assembly.
