Is provided integrally with the lock mechanism 15.

FIGS. 4A and 4B are a longitudinal sectional view and a side view showing the portion B in an enlarged manner. In the figure, reference numeral 12 denotes the foot. The above-mentioned flange portion 18 is formed on the foot portion 12 over the entire length in the front-rear direction. Immediately above the flange 18, a fixing pin 26 is provided so as to project in parallel with the flange 18. This fixing pin 2
6 has a function of holding the second damper 17 and a function of holding the lock mechanism 15 in the same manner as the fixing pin 19 of the portion A.

The second damper 17 is as shown in FIG. 5, and has substantially the same basic structure as the damper 16 provided at the position A. That is, the flange 18
And a pin insertion hole 28 into which the fixing pin is inserted. However, the pin insertion hole 28 provided in the second damper 17 is not formed in a tapered shape, but is formed in a straight tube with an inner diameter larger than that of the fixing pin 26. A torsion coil spring 29 having a coil shape larger in diameter than the fixing pin 26 is provided in the pin insertion hole 28 at one end 2 thereof.
9a and the other end 29b are respectively inserted into the pin insertion holes 28.
Are extended from the one end opening and the other end opening, and housed in the pin insertion hole 28.

The second damper 17 positions the pin insertion hole 28 and the flange insertion hole 27 in the fixing pin 26 and the flange 18, respectively, and pushes the damper 17 toward the foot 12. It is attached (see FIG. 4A). At this time, unlike the first damper 16 provided at the position A, the pin insertion hole 28 of the second damper 17 is not tapered, so that the pin insertion hole 28 can be assembled to the foot 12 with a small resistance. it can.

A lock plate 31 (lock plate), a spacer 32, and a guide plate 33, which constitute the lock mechanism 15, are provided at the protruding end of the fixing pin 26 taken out from the other end opening of the second damper 17. Are attached in this order, and finally, the washer 34 and the fixing nut 35 are fastened. That is, in the damper mounting structure provided at the position B, the fixing nut 35 functions as a stopper for the damper 17.

Next, the lock mechanism 15 will be described.
The lock plate 31 is rotatably held by the fixing pin 26, and has a rotation end 31a (FIG. 4B).
As shown in FIG. 3, the hook has a hook shape so as to be able to engage with the shaft-like engaging member 30 provided on the floor panel 13. The lower edge of the lock plate 31 has an arc shape, and has a function of rotating the lock plate 31 to a position shown by a dashed line in FIG.

On the other hand, one end 29a of the torsion coil spring 29 incorporated in the second damper 17 is connected to the foot 1
2 is fixed to an engaging hole (not shown) provided in
9b is engaged with the outer edge of the lock plate 31. As a result, the lock plate 31 is urged in the direction indicated by the dashed line arrow in the figure.

That is, before the lock plate 31 is engaged with the engagement member 30, the lock plate 31 is held in a state shown by a solid line in FIG. It is brought into contact with the engagement member 30, and is driven to rotate in the direction opposite to the arrow, against the urging force of the torsion coil spring 29 (the position shown by the one-dot chain line in the figure). And by pushing down this seat device,
The lock plate 31 engages with the engagement member 30 as shown in FIG.

As shown in FIG. 5, a notch 37 is provided on the other end of the second damper, and the other end of the torsion coil spring 29 is operated in accordance with the operation of the lock plate 31. 29b is configured to be able to rotate smoothly.

Next, the guide plate 33 will be described with reference to FIG.
This will be described with reference to FIG. On the other hand, the guide plate 33 is for guiding a portion (the portion B) of the foot portion 12 where the second damper 17 is provided so as to face the engaging member 30, and has an upper end portion. The foot 12 is fixed to an upper end by bolts and nuts (not shown), and a lower end extends toward the engaging member 30. The lower surface of the lower end serves as a guide surface 33a that contacts the engagement member 30 and guides the foot 12.

That is, the guide surface 33a is
As shown in (b), the central portion is provided in a concave shape with a concave upward, and the engaging member 30 can be guided to the central portion of the guide plate 33. The height of the center of the lower end surface of the guide surface 33a of the guide plate 33 is adjusted to be slightly higher than the lower surface of the second damper 17.

Therefore, when the seat device 10 is tilted, even if the posture of the seat device 10 is shifted forward and backward, the seat device 10 (foot 12) is accurately positioned by the guide plate 33. Is to be guided to.

On the other hand, when the seat device 10 is tilted as described above and the lock plate 31 and the engagement member 30 are engaged, the second damper 17 comes into contact with the engagement member 30. Therefore, the engagement member 30 is sandwiched between the second damper 17 and the lock plate 31. As shown in FIG. 4A, the lower end 17a of the second damper 17 is interposed between the flange portion 18 and the engaging member 30, and receives vibration and impact between the two. be able to.

According to such a configuration, the following effects can be obtained. First, there is an effect that the dampers 16 and 17 can be easily fixed with a simple configuration and hardly fall off.

That is, when the above damper is attached,
The operation of screwing with the tapping screws 4 and 7 as shown in FIGS. 8A and 8C of the conventional example is unnecessary, and it is only necessary to push the dampers 16 and 17 into the foot 12. Further, the damper 1 is provided by a head 20 provided integrally with the fixing pin 19 or the lock mechanism 15.
Since it is possible to prevent the members 6 and 17 from slipping off, unlike the conventional example shown in FIG. 8B, when they are simply inserted into the flange portion, they do not drop off during use.

Conventionally, in order to securely fix the damper, a method of screwing the tapping screw 4 from below as shown in FIG. 8A has been the most reliable method. With such a configuration, the head 4a of the tapping screw 4 is located on the lower surface side of the damper 3, so that the recess 3a needs to be provided at the lower end of the damper 3. However, with such a configuration, the load receiving surface of the damper is limited.

However, according to the present invention, the damper 16,
17 can be securely fixed, and the damper 1
Since it is not necessary to provide such a recessed portion on the lower surfaces of 6 and 17, the area of the load receiving surface of the damper is not limited.

Second, the load applied to the fixing pins 19 and 26 and the flange 18 can be reduced.
And fixing pins 19 and 26 can be effectively prevented from being damaged.

That is, FIG. 8A shown in the conventional example,
In the configuration shown in FIG. 8B, the damper is fixed only to the flange portion. Therefore, when the strength of the flange portion is weak, the damper is bent upward together with the flange portion by the load input to the damper (FIG. 8A). (Indicated by an arrow). In the configuration of FIG. 8C, the tapping screw 7 and the damper 8 may be easily damaged.

However, in the present invention, the damper 16
17 is not only the flange 18 but also the fixing pin 1
9 and 26 hold the foot 12. Therefore,
The external force inputted to the dampers 16 and 17 is received by the flange portion 18 and the fixing pins 19 and 2 are received.
6 is also held dispersed.

According to the structure of the present invention, the upper ends of the dampers 16 and 17 are located in close contact with the foot 12 over the entire inside of the bent portion of the flange portion 18. Therefore, the bending of the flange portion 18 is physically restricted by the dampers 16 and 17. That is, the damper itself has the flange portion 18.
Has a function as a reinforcing member. Because of these, the rigidity of the entire foot portion 12 is improved,
This has the effect that the fixing pins 19, 26, the flange portion 18, or the dampers 16, 17 can be reliably prevented from being damaged.

Third, by incorporating the lock mechanism 15 into the lock mechanism 15, there is an effect that an impact and a collision at the time of locking can be effectively prevented. According to such a configuration, the load applied to the fixing pin 26 holding the lock mechanism 15 can be reduced, and the lock mechanism 15 can be effectively prevented from being damaged.

Further, according to such a configuration, the engaging member 30 provided on the floor panel 13 can be elastically sandwiched between the second damper 17 and the lock plate 31, so that the vehicle travels. This has the effect of effectively preventing vibrations and the like from being transmitted to the seat device 10.
