However, with the above-mentioned devices and these conventional devices, it is necessary to operate the fixing device with one hand and lift the sheet with the other hand, making it difficult to remove the sheet. There is a disadvantage that the burden on the worker during the work is large and the work cannot be carried out quickly.

In addition, in the conventional device described above, when the wire row and the hook piece 13 are separated, the operator cannot judge whether they have been separated or not, so even after the wire row and the hook piece 13 are separated, there is no unnecessary The handle part 3 is repeatedly pulled, and as a result, the handle part 3
There is also a risk that the first hinge portion 5 may be torn to pieces.

OBJECTS OF THE INVENTION The present invention has been made in view of the current state of conventional vehicle seat fixing devices. By preventing the reattachment of the sheet so that the sheet can be lifted with both hands, and by giving the operator the necessary sense of moderation during this disassociation, unnecessary pulling operations are avoided. An object of the present invention is to provide a vehicle seat fixing device f that makes it possible to prevent damage to the device caused by this.

Structure of the Invention In order to achieve the above-mentioned object, in the present invention, a seat cushion frame of a vehicle seat is fixedly provided with a substantially U-shaped locked member, and a locking member is fixed to the seat cushion frame of a vehicle seat, while a locking member is fixedly attached to the vehicle floor from a fixed position. A seat fixing device It is provided with a hook piece that can be displaced to a fixed position and a handle part linked to the hook piece, and is completely fixed, and when fixing the sheet, the hook piece is set at the locking position and the locked object is fixed. In a structure in which the hook piece is engaged with the body, and when the sheet is removed, the hook piece is moved to the release position by operating the flat part of the -J handle, and the hook piece is disengaged when the sheet is removed. Reassociation prevention means is provided for preventing reassociation with the locked object and supporting the handle portion in the disengaged position.

Example An embodiment of the present invention will be described below with reference to the drawings.

Note that parts and parts that are the same as those of the apparatus described above will be designated by the same reference numerals and redundant explanations will be omitted. - Figures 5 and 6 show the first embodiment of the present invention, and the handle part 3 has opening edges 7a and 7m on the long side of the opening lower part, and the first hinge part 5 has Protrusions 4 and 29 serving as reassociation prevention means are provided at adjacent positions. the raised portion four;
As shown in FIG. 6, 29 includes a stopper portion (9) that is perpendicular to the front 8-pin long side opening edges 7a, 7a formed on the first hinge portion 5 side, and a handle. A tapered portion 31 is formed in the distal direction of the portion 3.

In this embodiment with the above configuration, when fixing the seat 26, as shown in FIG. 6(a) and FIG. 7(a),
The tapered portion 31 of the raised portion 4 is brought into contact with the circumferential surface of the wire path, and the lower end of the wire path is engaged with the hook piece 13. As a result, the cylinders 26 are firmly fixed to the vehicle body floor.

When removing the seat) 26, the operator should
, as shown in FIG. 7(b), handle portion 3'f: pulled in the direction of arrow C. As a result, as described above, the protrusion 6 presses the plate 14, and the hook piece 13 presses the plate 14.
Then, the wire is disengaged from the hook piece 13. When the handle part 3 is pulled, the tapered surface 31 of the raised part 4 comes into sliding contact with the peripheral surface of the wire, and the feeling of resistance during this sliding contact is transmitted to the operator via the handle part 3.

When the protrusion 4 crosses the wire 28, the resistance disappears, and when the operator senses this and releases his/her hand from the handle 3, a part of the stopper of the protrusion 4 becomes a part of the wire path. , and the handle portion 3 is prevented from moving in the opposite direction of arrow C. Therefore, the protrusion 6 stops while pressing the plate 14, and the hook piece 13 integrally provided on the plate 14
is prevented from reasserting with the wire array.

Therefore, the operator does not have to keep pulling the handle 3 and can lift the sheet with both hands.

Furthermore, since it can be determined that the hook piece 13 is in the disengaged state by the disappearance of the aforementioned resistance, it is possible to prevent unnecessary tension from being applied to the handle part 3. 3 being torn off from the first hinge portion 5 can be prevented from occurring.

FIGS. 8 and 9 show a second embodiment of the present invention, in which a coil spring 32 is used as the reassembly preventing means. That is, inside the fixing device main body 1, a coil spring 32 that presses the wire 28 upward when the wire 28 is engaged with the hook piece 13 is held between the claws 33.

In this embodiment, when the seven wire hook pieces 13 are engaged, the wire path is pressed against the hook pieces 13 by the biasing force of the coil spring 32. When the wire is separated from the hook piece 13, the wire path is sprung upward by the coil spring 32. In the past, even if the worker took his hand off the handle 3 in this state, the hook piece 13 would not engage with the wire wing again, and the worker could remove the sheet with both hands. can be done. Furthermore, when the wire row and the hook piece 13 are separated, the sheet is thrown up together with the wire row, so that the operator can determine whether the wire path and the hook piece 13 have been separated, and This eliminates the need for repeating unnecessary pulling operations, and prevents problems such as the handle portion 3 being sheared off by the first hinge portion 5.

FIG. 10 shows a third embodiment of the present invention, in which a plate spring 34 is used as the reassembly prevention means.

In other words, the leaf spring 1 is configured to press the wire 4 upward when the wire 4 is engaged with the hook piece 13.
It is supported by 35.

In this embodiment as well, as in the second embodiment, when removing the sheet, the wire 4 and the hook piece 13 are prevented from being reattached, making it possible to perform the sheet removal operation with both hands, and preventing the sheet from being thrown up. This makes it possible to determine whether the wire 4 and the hook piece 13 have come apart, and to prevent the handle part 3 from being sheared due to unnecessary pulling of the handle part 3.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention prevents the hook piece and the locked object from being reattached when an automobile seat is removed, and supports the handle portion linked to the hook piece in the disengaged position. Since the re-assembly preventing means is provided, even if the hand is released from the handle part during the sheet removal operation, the hook piece and the locked object will not be re-engaged. Therefore, the work of lifting the seat can be performed with both hands, and the work load when removing the seat can be reduced. In addition, since the operator can determine the dissociation of the hook piece and the locked object from the outside, there is a possibility that the disassociation operation may be continued unnecessarily. can also be prevented,
It is also possible to prevent damage to the sheet fixing device caused by this and improve fire resistance.
