[Prior art]

 Generally, a slide rail mechanism that slides the seat in the vehicle front-rear direction with respect to the floor is provided between the floor of the vehicle body and the seat. The slide rail mechanism is provided on the floor and has an upper end. A lower rail having flange pieces protruding from the position in the left-right direction of the vehicle body, and an upper rail having a sliding contact portion which is provided at a lower portion of the seat and is in sliding contact with each of the flange pieces are provided.

The rear end of the lower rail is attached to the floor by fastening a seat anchor fixed to the rear end to the floor with a fastener such as a bolt. The fastener and the seat anchor exposed at the rear end of the lower rail are covered from the outside by a seat anchor cover.

Further, in this type of seat anchor cover, for example, as disclosed in Japanese Utility Model Laid-Open No. 62-115936, the edge portion of the rear end of each flange piece at the rear end of the lower rail is sandwiched from above and below. Some seats are provided with a cover part that covers them up. With such a seat anchor cover, not only the seat anchor (fastener) but also the edge part of the rear end of each flange piece at the rear end part of the lower rail is covered up. Thus, the foot of the occupant seated on the rear seat behind the seat is prevented from coming into contact with the edge portion of the rear end of each flange piece.

[0005]

[Problems to be solved by the device]

 By the way, in the case of the seat anchor cover having the above-mentioned cover portion, the edge portion of the rear end of each flange piece is sandwiched by the cover portion from the up and down direction to be covered, so that when moving the seat backward, When the upper rail is slid backward with respect to each flange piece of the lower rail, the upper rail comes into contact with the cover portion at the rear end position of the lower rail, and the amount of rearward movement of the seat is restricted.

Therefore, it is conceivable that the sliding contact portion of the upper rail, which is in sliding contact with each flange piece of the lower rail, is enlarged in the vertical direction in consideration of the contact with the cover portion of the seat anchor cover. Along with the increase in the size of the contact part, new problems such as looseness on each flange piece (sliding contact surface) of the lower rail and an increase in the weight of the upper rail will be introduced.

The present invention has been made in view of the above points, and an object of the present invention is to provide a rear end of a seat anchor and a lower rail while ensuring a rearward movement amount of a seat without increasing the size of the upper rail. The purpose is to construct a seat anchor cover that covers the parts.

[0008]

[Means for Solving the Problems]

 Means for Solving the Problems In order to achieve the above-mentioned object, a solution means taken by the present invention is a slide rail mechanism that is a seat anchor cover and slides the seat between the floor of the vehicle body and the seat in the longitudinal direction of the vehicle body with respect to the floor. The slide rail mechanism is provided with a lower rail having flange pieces provided on the floor and projecting from the upper end in the left-right direction of the vehicle body, and a lower rail provided on the lower part of the seat, which is provided on each of the flange pieces. And an upper rail having a sliding contact portion that is slidably contacted with each other. A seat anchor for attaching the rear end of the lower rail to the floor is provided at the rear end of the lower rail, and a seat anchor cover for covering the seat anchor and the rear end of the lower rail from the outside is provided. Further, each of the flange pieces is provided with a cutout portion formed by cutting out a rear end of each flange piece at a rear end portion of the lower rail, and a sliding contact surface for slidingly contacting the sliding contact portion of the upper rail with the seat anchor cover. And a continuous piece integrally provided with the notch so that the sliding contact surface is continuous rearward in a plane with the sliding contact surface of each flange piece with respect to the sliding contact portion of the upper rail. It is what

[0009]

 With the above configuration, in the present invention, the rear end portions of the seat anchor and the lower rail are hidden from the outside by the seat anchor cover.

In that case, the continuous piece integrally provided on the seat anchor cover is slidably contacted with the sliding contact portion of the upper rail with respect to the notch portion formed by cutting out the rear end of each flange piece at the rear end portion of the lower rail. Since the sliding contact surface is aligned with the notch so that the sliding contact surface of each flange piece with the sliding contact portion of the upper rail is continuous in the rearward direction, it is positioned in front of the rear end of the lower rail. The edge portion at the rear end of each flange piece is covered by the continuous piece from behind.

Moreover, as described above, according to the continuous piece, when the upper rail is slid rearward with respect to each flange piece of the lower rail, the sliding contact surface of each flange piece of the lower rail with respect to the sliding contact portion of the upper rail. The sliding contact surface of the continuous piece continues to make sliding contact, and the upper rail does not contact at the lower rail rear end position like the one that covers the edge part of the rear end of each flange piece by sandwiching it from the up and down direction. The amount of movement to the rear of the seat is prevented while preventing the rattling of the sliding contact part of the upper rail against the sliding contact surface of each flange piece and the increase in the weight of the upper rail due to the increase in the size of the sliding contact part of the upper and lower parts. Is expanded.

[0012]

[Effect of device]

 As described above, according to the seat anchor cover of the present invention, the sliding contact surface of the integral continuous piece of the seat anchor cover is continuously flushed rearward with respect to the sliding contact surface of each flange piece. Since it matches the notch at the rear end of the lower rail, the edge of the rear end of each flange piece can be hidden from the rear, and the sliding contact surface of the continuous piece continues to slide against the sliding contact portion of the upper rail. As a result, the rearward movement amount of the seat can be increased without enlarging the sliding contact portion of the upper rail.
