FIGS. 9 to 16 are views for explaining a cover mounting procedure in the rail cover mounting structure according to the embodiment of the present invention. As shown in FIGS. 9 and 10, the cover 15 is tilted by raising the rear end, and the right and left front end side engaging claws 16 are slid against the upper surface of the corresponding flange 28 of the bracket 11. To move from back to front. As shown in FIGS. 11 and 12, both front end side engaging claws 16 are engaged with the corresponding concave portions 32 of the bracket 11. As shown in FIGS. 13 and 14, the upright portion 33 is fitted into the notch portion 16b,
As shown in FIGS. 15 and 16, the lower claws 51 and the lower claws 53 are engaged with the engaging holes 21 while lowering the rear end of the cover 15.
Then, as shown in FIG. 8, the cover 15 is mounted in a state where the lateral claws 51 and the downward claws 53 are engaged with the edge of the engaging hole 21 to prevent the positioning and the positioning.

The cover 15 thus attached is
When the front seat 10 is at the front, as shown in FIG. 2, it covers the rear side surface of the lower seat rail 12, and when the front seat 10 is at the rear, as shown in FIG.
Not only the side surface of the rear part of the lower seat rail 12 but also the lower part of the upper seat rail 14 protruding backward
8 and covers the side surface of the portion of the upper seat rail 14 that fits into the guide groove 18 of the lower seat rail 12.

According to the rail cover mounting structure according to the embodiment of the present invention, the cover 15 is fitted not only to the side surface of the lower seat rail 12 but also to the parallel guide groove 37 of the lower seat rail 12. Grease can be prevented from adhering to shoes or the like, and when the front seat 10 is located at the rearmost position, the grease is slightly behind the rear end of the upper seat rail 14. Since the cover 15 is continued, the sliding amount of the front seat 10 can be easily grasped by comparison with the length of the guide groove 18 of the cover 15, and the front end is placed on the flange 28 of the bracket 11 with the cover 15 inclined. After the front end side engaging claw 16 is engaged with the engaging portion 20 while the side engaging claw 16 is placed and slid from back to front, the engaging hole 2
By simply lowering the rear end of the cover 15 while inserting the rear end side engaging claw 17 into the bracket 1, the cover 15 can be secured to the bracket 11 and positioned and mounted, and this mounting is extremely easy and difficult to remove. There is an advantage.

The present invention is not limited to the above embodiment, but can be variously modified. For example, the engaging hole 21 may be oval or circular instead of square, and the downward-facing pawl 53 of the rear-end engaging pawl 17 may be provided with a rearward-facing pawl for retaining to omit the lateral-facing pawl 51. Can,
Flanges 2 on both sides instead of the rising portion of bracket 11
An upper plate may be provided between the upper ends of the upper and lower plates 8, 28, and an engagement hole may be formed in the upper plate.

[0019]

According to the present invention, grease adheres to shoes or the like by providing a cover at a position covering at least the side surface of the rear end of the lower seat rail and the rear end of the upper seat rail when the seat moves rearward. The lower seat rail and the upper seat rail can be covered with a cover to improve the appearance without the need to provide a continuous guide groove along the front and rear direction, and the guide groove can slide the upper seat rail. The guidance provides an effect that the slide amount of the sheet is easy to understand. Further, one end side engaging claw is provided on one end side of the cover, an engaging portion is provided on the bracket at a position corresponding to the one end side engaging claw, and the one end side engaging claw is engaged with the engaging portion. The other end of the cover is provided with an engaging claw, and the bracket is provided with an engaging hole into which the other engaging claw can be inserted. There is an advantage that the cover can be easily attached and positioned and the cover is hard to be detached by engaging the other end side engaging claw to prevent the slipping and positioning.
