2. Description of the Related Art In a conventional one-box car or the like,
Since both occupant loading and luggage loading are used, an average number of seats and luggage loading space are provided. There are cases where a detachable seat is provided in places other than the driver's seat and the passenger seat, and cases where a movable seat is provided.

[0003] When there is a lot of luggage, the seat provided with a detachable seat is removed, and the seat provided with a movable seat is moved forward to secure a luggage space. Such a seat apparatus is disclosed in Japanese Utility Model Laid-Open No. 4-131533 and Japanese Utility Model Publication No.
No. 11226 is known. Japanese Patent Application Laid-Open No. 63-137054 discloses a configuration in which a lock mechanism for tilting forward and removing can be released by one lever.
-305346 exists.

In the case of a detachable seat, as shown in FIG. 9, a lock mechanism 11 is provided between a front-rear slide mechanism 1 including a fixed rail 3 and a movable rail 5 and a striker 9 provided on a vehicle floor 7. When the lock mechanism 11 is released, the seat can be removed from the striker 9 on the vehicle floor 7 together with the front and rear slide mechanism 1.

The lock mechanism 11 includes a lock body 13 mounted on the fixed rail 3 side, a lock release knob 15 provided on the lock body 13, and a lock release operation lever unit 17. Latch claw 1
4 is adapted to be engaged with a striker 9 provided on the vehicle floor 7.

In the case of the detachable seat shown in FIGS. 6 to 8A and 8B, as shown in FIG. 8B, the front hinge 12 and the rear lock mechanism 11 are provided. When the length L with the lock body 13 is different from the length of the vehicle floor 7 up to the striker 9, the error has to be absorbed by the lock body 13 of the lock mechanism 11.

In the detachable seat, a lock body 13 is fixed to the fixed rail 3 by bolts 19, and a guide member 23 extending in the left-right direction is fixed to a nut member 21 provided on the upper part of the lock body 13. The distal end side of the guide member 23 is inserted into an elongated hole 25 formed in the upper part of the lock body 13 and extending in the front-rear direction, so that the position of the lock body 13 can be adjusted back and forth.

In this case, the wire spring 27 regulates the play of pressing the nut member 21 and moving the nut member 21 back and forth.
The wire spring 27 presses the guide member 23 downward. A leaf spring 29 is provided outside the nut member 21 so as to reduce friction in the front-rear direction by making line contact.

[0009]

In the case of a conventional detachable seat, an elongated hole 25 is formed in the lock body 13, the guide member 23 is fixed to the nut member 21, and the wire spring 27 and the leaf spring 29 are attached. It is necessary, the shapes of the nut member 21 and the guide member 23 become complicated, and the wire spring 27 and the leaf spring 29 are used for holding back and the like, so the number of parts and the number of processing steps increase, and the assembling work becomes complicated. However, there is a disadvantage that the cost is increased.

The lock body 42 is swingably adjustable about a bolt 55 inserted into a round hole 53a as the bolt hole 53. In this embodiment, the center bolt hole 53 among the plurality of bolt holes 53 is a round hole 53a.
And the bolt holes 53 on both sides are
Is formed in an arc-shaped long hole 53b centered on the round hole 53a, but the bolt hole 53 may be formed of one round hole 53a and one long hole 53b.

According to such a configuration, as shown in FIG. 3, the lock body 42 rotates around the round hole 53a as the central bolt hole 53, and the striker 9 provided on the vehicle floor 7 on the lower side. The position of the latch claw 43 to be engaged with the front and rear can be adjusted within the range of the dimension L1, and the length variation and error between the front and rear slide mechanism 31 and the striker 9 as a mounting portion of the vehicle body. Can be absorbed.

FIG. 5 shows a different embodiment of the vehicle seat attaching / detaching mechanism according to the present invention. The shapes of the fixed rail 33 and the movable rail 35 of the front-rear sliding mechanism 31 in the embodiment described above are shown. In this embodiment, a connecting plate 61 having an L-shaped cross section is fixed to the lower portion of the fixed rail 33, and the connecting plate 61
The bolt 51 and the nut 5
7 is fixed. The configuration of the round holes 53a and the elongated holes 53b as the bolt holes 53 of the mounting portion 51 is the same as in the above-described embodiment.

[0024]

As described above, the embodiment of the vehicle seat attaching / detaching mechanism according to the present invention is described. According to the vehicle seat attaching / detaching mechanism according to the first aspect of the present invention, the lock mechanism is provided on the vehicle floor. A lock body having a latch claw attached to the fixed rail side of the front-rear slide mechanism engaged with the striker provided on the movable rail; an operation lever for unlocking operation pivotally supported by the movable rail; and the latch claw. A lock release knob provided between the lock body and an operation lever, wherein a plurality of bolt holes are formed in an upper portion of the lock body, and any one of the plurality of bolt holes is formed in an elongated hole. The upper part is attached to the fixed rail side by bolts and nuts through a round hole and a long hole as a bolt hole, and the lock body can be swingably adjusted around a bolt inserted into the round hole as the bolt hole. If there is a dimensional variation or error between the front-rear slide mechanism and the striker as an attachment part of the vehicle body, this dimensional variation or error is centered on the bolt inserted into the round hole. Can be absorbed by adjusting the rotation.

According to the second aspect of the present invention, the locking mechanism is mounted on the fixed rail side of the longitudinal slide mechanism which is engaged with a striker provided on the vehicle floor. A lock body having a latch claw, an operation lever for unlocking operation pivotally supported by the movable rail, and a lock release knob provided between the latch claw and the operation lever. A plurality of bolt holes are formed in the upper part, a central bolt hole among the plurality of bolt holes is formed as a round hole, and the bolt holes on both sides are formed as arc-shaped long holes centered on the central bolt hole, The upper part of the lock body is attached to the fixed rail side with bolts and nuts through round holes and oblong holes as bolt holes,
Since the lock body is swingably adjustable about the bolt inserted into the round hole as the central bolt hole, the dimensional variation and error between the front-rear slide mechanism and the striker as the mounting portion of the vehicle body are changed. If exists,
When the lock body is rotated around a bolt inserted into a round hole serving as a central bolt hole, the bolt relatively moves along an arc-shaped elongated hole on both sides, thereby rotating and adjusting the lock body. Thereby, dimensional variations and errors can be absorbed.

According to the vehicle seat attaching / detaching mechanism of the present invention, it is possible to absorb variations and errors in dimensions of the seat front / rear sliding mechanism and the vehicle body mounting portion with a simple structure, and to reduce the number of parts. It is possible to obtain a vehicle seat attachment / detachment mechanism which can improve the appearance, facilitate the assembling work, and have excellent economy.
