2. Description of Related Art
As shown in FIG. 8, in a front seat for an automobile, in order to prevent small items from falling from a gap between a seat cushion 110 and a central control station C towards an action area A of a lift mechanism (not shown) of the seat cushion 110, a cover member 117 hanging towards the lower side of the seat cushion 110 is provided on the side portion of the seat cushion 110 so as to cover the gap (see Japanese Patent Application Publication No. 2013-226932 (JP 2013-226932 A)).
In this case, the seat cushion 110 comprises a cushion frame 111 and a cushion cover 115 which covers an outer side of a cushion frame 111 that serves as a base body of the vehicle seat such that a soft cushion (not shown) is interposed between the cushion frame 111 and the cushion cover 115. The cushion cover 115 is integrated with the cushion frame 111 by engaging a hook 116 with a lower end portion 111a of the cushion frame 111. At this time, the lower end portion 111a of the cushion frame 111 is located lower than the position of the cushion cover 115 on the side of the central control station C, and is located on the inner side of the seat cushion 110. Thus, the position of the hook 116 also is the same position, and the lower end portion of the cushion cover 115 is bent to be separated from the central control station C. Thus, the action area A of the lift mechanism on the lower portion of the seat cushion 110 is opened on the side of the central control station C, and small items can fall easily. As a countermeasure, in the invention of JP 2013-226932 A, the action area A is closed on the side of the central control station C by stitching the cover member 117 on the cushion cover 115.
However, according to the vehicle seat described in JP 2013-226932 A, since the cover member 117 is newly provided, there exists a problem that the manufacture cost rises. For example, the time for trimming the cover member 117 is unnecessarily spent. Moreover, the time for stitching the cover member 117 on the cushion cover 115 is also unnecessarily spent.
