According to the force-force seat mounting device, the movable frame 4 must first be installed on the installation line for attaching the seat cushion 5 and the seat pancro, which requires a considerable amount of line man-hours. Since it is a large member spanning the seat pancro, it has a large weight, and if the seat cushion 5 is not moved forward or backward, the angle of inclination of the seat bank 6 will change. It was a structure that could not be changed.

In view of the conventional examples of force and force, the present invention provides a seat bank that is supported by a guide means that can be attached to the vehicle body and can freely slide up and down, and a slide rail that can be attached to the vehicle body and can be slid forward and backward. The seat cushion is supported by the seat cushion mounting means, and the locking means of the positioning means formed on the frame of the seat bank can be connected and detached to the mounting bin at the rear of the seat cushion, and the seat cushion mounting means is The present invention provides a seat mounting device formed of a fitting support portion and a mounting pad portion capable of supporting an insertion locking member and an abutting bending member formed on a slide rail.

The details will be explained below based on FIGS. 2 to 5. First, the seat mounting device according to the present invention is such that the lower part of the seat back 11 and the rear part of the seat cushion 22 can be freely connected and detached by the positioning means 13. - The upper part of the seat bank 11 is made vertically movable by the guide means 12, and the inclination angle of the seat bank 11 is made variable by moving the seat cushion 22 connected to the seat bank 11 back and forth.

The guide means 12 can be attached to the upper body 14 of the seat bank 11 from above, and in the illustrated example, an arbitrary number of guide pins 16'2 are protruded laterally at appropriate positions on the upper part of the seat bank frame 15. The vehicle body 14 is provided with a guide receiving portion 17 for receiving the guide pin 16 from above and slidably up and down.

Note that the guide means 12 is not limited to this example, and a guide pin (not shown) may be provided on the seat bank frame with a guide receiving portion facing toward the vehicle body. On the other hand, any shape or structure can be adopted as long as it can be attached from above and can be moved up and down.

The positioning means 13 is formed in the lower part of the seat bank frame 15, and has a connecting groove 18 cut into the lower end thereof and a hook-shaped locking means 20 which is biased against the connecting groove 18 via a spring 19. It can be attached to and detached from the seat cushion.

In the specific example shown in FIGS. 2 and 3, this positioning means 13 is provided at the rear end of a seat cushion 22 that is movable in the front-rear direction (in the direction of arrow A in FIG. 3) via a slide rail 21. The mounting pin 23 is engaged with the mounting pin 23, specifically, the mounting pin 23 is inserted into the connecting groove 18, and the locking means 20 is provided so as to be rotatably connected.

Therefore, the lower position of the seat bank as the seat cushion moves back and forth? By changing the angle of inclination of the sheet bank, the angle of inclination of the sheet bank can be made variable as shown by X1 s Yl in FIG.

As shown on the upper side, a guide means 12 is provided that can be freely attached to the upper part of the seat bank 11 and the vehicle body 14 from above, and the lower part of the seat bank 11 is directly attached to the seat cushion 22, which was previously considered indispensable. One of the features of the present invention is that there is no need for a movable frame.

Furthermore, as shown in the specific example of FIGS. 2 and 3, a slide rail 21 is fixed in advance to the lower part of the seat cushion 22 to prevent the seat bank 11 from being connected to the movable seat cushion 22. The seat cushion 22 is attached to the seat cushion 22 via a seat cushion mounting stage 25 which, on the one hand, stops the rear end portion of the slide rail 21 for insertion and locking, and on the other hand, allows the front end portion of the slide rail 21 to be fixed freely. By attaching the seat cushion to the vehicle body 14, the seat cushion can be easily attached, and this is also another feature of the dubatsu.

This seat cushion attaching means 25 has a rear leg portion 2 which has a locking portion for insertion of the slide rail 21 on the one hand.
An upper bent piece 32 is formed at 6, this part is used as a rear end for insertion and locking, a guide flange 31 is placed at a position corresponding to the width size of this rear foot part 26, and an upper bent piece 32 is formed at the end of the guide flange 31. A hook-shaped fitting support part 30 for receiving and locking is formed, and on the other hand, the front leg part of the slide rail 21 is formed into a bent part 28 which is a bending member for contact.
A mounting pad portion 29 is provided corresponding to the mounting pad portion 29, and a bolt 27 can be freely fitted into the mounting pad portion 29 (second, third,
Figure 5).

Next, the effect will be explained.

First, the installation state of the seat cushion will be explained.

In the specific example shown in FIGS. 2 and 3, the seat cushion mounting means 25 is fixed to the vehicle body 14, and the rear foot portion 26 of the slide rail 21 provided in advance at the bottom of the seat cushion 22 is attached to the rear leg portion 26 of the slide rail 21. If it is pushed in while being guided, the upper bent piece 32 enters the fitting support part 30 and is locked there, and the front leg is positioned, and the bent part 2E for contact is attached with the bolt 27. It can be installed simply by fixing it to the NAND part 29.

That is, the seat cushion 22 can be attached by simply inserting and fixing the rear end of the slide rail into the fitting support part and fixing the front end with bolts.

Next, the installation state of the seat bank will be explained.

The seat bank 11 can be mounted and positioned with respect to the mounting pins 23 provided on the seat cushion 22.

In either case, the mounting can be accomplished simply by pushing the positioning means 13 onto the mounting pin 23.

That is, when the hook-shaped locking means 20 moves to allow the insertion of the mounting pin 23 and the mounting pin 23 enters the connecting groove 18 to an appropriate position, the mounting pin 23 is pushed forward by the bias of the spring 19. Figure 4 A5 and C].

When installing the lower part of the sheet bank 11 like this, the upper part of the sheet bank 11 can be easily installed by simply inserting the guide pin 16 from above into the guide receiving part 17. It can be easily installed.

Next, the reclining state will be explained.

When changing the inclination angle of the seat bank 11, in the case of the specific example shown in FIGS. 2 and 3, the relationship between the seat back 11, the seat cushion 21m mounting pin 23, and the connecting groove 18 is a kind of hinge connection. For example, as shown at Accordingly, the inclination angle of the sheet bank 11 changes accordingly.

As explained above, when using the seat mounting device according to the present invention, the upper part of the seat bank is slidable, and the lower part of the seat bank is detachable from the movable seat cushion. Since the inclination angle of the seat bank can be varied by interlocking the seat banks, the movable frame, which was conventionally considered essential for seat mounting devices that move the lower part of the seat bank to change the inclination angle of the seat bank, can be omitted. Since it can be attached to the vehicle body, the structure is simplified and the number of installation steps can be reduced, and it is also possible to reduce weight and cost. Since the seat cushion can be freely attached to the vehicle body through the seat cushion attachment means Z which receives the rear end of the seat cushion and allows the front end to be fixed, the work of attaching the seat cushion is extremely easy. This has great effects such as making it possible to use sewn products for both the kungjong and the sheet bank.
