The present invention relates to a seat slide device including an upper rail that is slidably guided in the longitudinal direction on the long lower rail and that is attached and fixed to the seat body side.

[0002]

2. Description of the Related Art In a conventional vehicle such as a one-box car, both occupant loading and luggage loading are used, so that an average number of seats and luggage loading space are provided. In addition, there are cases where a removable seat and a movable seat are provided other than the driver seat and the passenger seat. A configuration is also known in which a base of a reclining mechanism is attached to an upper rail side, a seatback is attached to an arm of the reclining mechanism, and the seatback is provided so as to be able to tilt forward and backward.

In such a vehicle, an area where a seat can be seated and an area where a seat cannot be seated are provided on a fixed rail, and an interlock member is provided on an upper rail. There has been proposed a lock mechanism for a seat slide device that cannot be moved to a range where a seat cannot be seated.

A conventional example is disclosed in, for example, Japanese Patent Application Laid-Open
As described in Japanese Patent No. 5163, a slide lock mechanism and an interlock member are provided, and the slide lock mechanism is unlocked by an operation lever, and the interlock member is unlocked by tilting the seat back forward. When the seat is in a seatable range, the operation lever releases the lock state of the slide lock mechanism, and the seat back is tilted forward to release the lock state of the interlock member. Are proposed.

As shown in FIG. 4, a long lower rail 12 of a sheet slide device 11 is fixed to a recess 5 provided in the floor carpet 3 of the sheet mounting floor 1 by bolts 7 to the sheet mounting floor 1. The upper rail 13 is slidably supported in the longitudinal direction on the long lower rail 12, and a plurality of lock holes 15 are formed in a side portion of the long lower rail 12 as a slide lock mechanism 14. The latch 17 having a latch claw 18 that protrudes to one side in the lateral direction of the long lower rail 12 and is selectively locked in a plurality of lock holes 15 on one side of the long lower rail 12 is made movable in the lateral direction by an operation lever. A configuration has been proposed. A finisher 19 is mounted on the upper part of the long lower rail 12.

[0006]

However, the lower rail 12 of the conventional seat slide device 11 as described above.
When the is formed long, the processing of each part is complicated, and there is also a problem of backlash due to dimensional errors of each part, and there is a disadvantage that the weight increases when trying to maintain strength against a load, and The lower rail 12 is placed in the recess 5 provided in the floor carpet 3 on the side of the vehicle body floor 1, and as the slide lock mechanism 14, a latch claw 18 of a latch 17 is provided.
When it is possible to move forward and backward in the lateral direction, the vicinity of the concave portion 5 of the floor carpet 3 is deformed due to cushioning or the like, and there is a risk that the latch claw 18 may interfere with the floor carpet 3 to obtain a reliable lock state. There was a possibility that the operation could not be performed. In addition, there is a possibility that dust on the sheet mounting floor 1 may fall from the opening of the lower rail 12 into the lower rail 12 and a smooth sliding operation of the upper rail may not be obtained. In addition, it is impossible to obtain a simple and inexpensive configuration that appropriately supports the weight of the occupant and the like.

SUMMARY OF THE INVENTION It is an object of the present invention to prevent rattling of the upper rail of the seat slide device in the vertical and horizontal directions, to form the opening of the long lower rail to be narrow, and to prevent dust on the floor surface from being contaminated by the opening of the lower rail. Can be prevented from falling into the inside of the lower rail from the part, it can be bolted to the floor of the long lower rail from the narrow opening of the long lower rail, and when the vicinity of the recess of the floor carpet is deformed Also, there is no danger that the latch claws will interfere with the floor carpet, a secure lock state can be obtained, the cost is inexpensive, the mounting work can be performed simply and quickly, and the frictional resistance is reduced, and the operation is reduced. An object of the present invention is to provide a seat slide device capable of improving the operability.
