It fits into one notch 60. When the holder 56 is folded toward the support arm 52, the lock shaft 81 is fitted into the second notch 62 formed at the lower end of the pair of holding portions 56A. .

Next, the operation and effect of this embodiment will be described.

First, the child seat 12 is fixed to the vehicle seat 34. Specifically, in the case of the present embodiment, the seat belt device 44 is used.

As shown in FIGS. 1 and 2, the base 16 is placed on a seat cushion 36 of a vehicle seat 34. At this time, the base 16 is secured so that the bottom surface of the seat portion 16A of the base 16 is securely placed on the seat cushion 36 and the back surface of the backrest portion 16B of the base 16 is securely contacted with the seat back 38. set. After that, the rail portions 40 on both sides 16C of the base 16
The webbing 46 of the seatbelt device 44 is wound around the pair of left and right webbing mounting recesses 42 formed in
The base 16 is firmly fixed to the vehicle seat 34 by engaging the tongue plate with the buckle device. Next, the child seat body 14 is attached to the base 16.
Is attached.

Next, mounting work of the child seat support device 10 is performed. At this time, the support arm 52 of the child seat supporting apparatus 10 has already been connected to the base 16.
It is fixed to the bottom side of. Therefore, the mounting operation of the child seat support device 10 includes the lock shaft 81
After confirming that the support leg 50 is securely engaged with the first notch 60 of the holder 56, only the height adjustment of the support leg 50 may be performed.

The operation of adjusting the height of the support leg 50 is performed in the following manner. First, the bolt 66 is loosened so that the slider 54 can move up and down with respect to the holder 56. Next, the slider 54 is extended and contracted with respect to the holder 56, and the lower end of the slider 54 is vertically contacted with the vehicle body floor 48. Thereafter, the bolt 66 is screwed into the fixing hole 64 of the slider 54 at that position.

By setting the pitch of the fixing holes 64 to be small and forming many fixing holes 64 in the slider 54, the displacement between the bolt 66 and the fixing holes 64 can be eliminated. However, if too many fixing holes 64 are formed, the rigidity of the holder 56 may be reduced. Therefore, if there is such a concern, the legs 90 indicated by the two-dot chain line in FIG. You may make it attach to a lower end part. In other words, the leg 90 formed in the flared shape has a function of finely adjusting the height of the support leg portion 50 and a function of securing a stable support state by increasing a contact area of the slider 54 with the vehicle body floor 48. There are both.

In the above description, the base 1
Although the child seat main body 14 is attached first after the fixing of the child seat 6, the child seat support device 10 may be attached first after the base 16 is fixed. When the above operation is completed, the child seat 12 is moved to the vehicle seat 3 by the child seat support device 10.
4 is supported in a plunging manner from the front side.

On the other hand, when removing the child seat 12 from the vehicle seat 34, the bolts 66 are loosened, the slider 54 is slid to the holder 56 side, and then the bolts 66 are tightened again and temporarily fixed. In this state, the child seat 12 may be taken out from the side door of the vehicle,
If the support leg 50 interferes with the surroundings of the side door (such as a rocker) and is difficult to take out, the support leg 50 is further folded.

Specifically, first, the slide button 82 is pressed in the release direction (the direction of the arrow in FIG. 4) against the urging force of the compression coil spring 88. When the slide button 82 is pressed in the direction of the arrow, the lock shaft 81 fixed to the slide button 82 is slid from the front end to the rear end along the elongated hole 74 of the support arm 52. For this reason, the lock shaft 81 engaged with the first notch 60 of the holder 56 is disengaged from the first notch 60, and the holder 56 can be relatively rotated with respect to the support arm 52. Therefore, the holder 56 is moved together with the slider 54 into the support arm 5.
Rotate to the 2 side. When the holder 56 is rotated by about 90 degrees toward the support arm 52, the lock shaft 81 and the holder 5 are rotated.

2 is engaged. Thereby, the folding operation of the child seat support device 10 is completed.

Here, when the vehicle is suddenly decelerated in a state where the child seat supporting device 10 is mounted, the child seat 12 is moved to the vehicle seat 34 by an inertial force acting on the child seat 12 and a child sitting on the child seat 12. About the constraint point (fixed point by the seat belt device 44).

However, in the present embodiment, as described above, the child seat support device 10 including the support leg portion 50 and the support arm portion 52 is shaped like a plug when viewed from the side of the vehicle, and has a child seat 12. I support.
That is, the rear end of the support arm 52 arranged with the vehicle longitudinal direction as the longitudinal direction is connected to the bottom surface side of the base 16, and the front end of the support arm 52 is arranged with the vehicle vertical direction as the longitudinal direction. Since the lower end of the support leg 50 is connected to the upper end of the support leg 50 and the lower end of the support leg 50 is supported by the vehicle body floor 48, the load of the child seat 12 that is inclined forward is initially reduced by the support arm 52.
, And then to the support leg 50 supporting the support arm 52, and finally supported by the vehicle body floor 48. Therefore, according to the present embodiment, it is possible to reliably prevent the child seat 12 from leaning forward and sinking into the seat cushion 36 of the vehicle seat 34 when the vehicle suddenly decelerates.

In particular, in this embodiment, the lock shaft 8
By engaging the first member 1 with the first notch 60 of the holder 56, the relative rotation between the support arm portion 52 and the holder 56 is reliably prevented (that is, the locked state is established). Acting as a single rigid body as a whole. Therefore, also from this point, the performance of preventing the child seat 12 from leaning forward when the vehicle is suddenly decelerated is enhanced.

In addition, in the child seat support device 10 according to the present embodiment, the support leg 50 is used for the vehicle seat 34.
And the support arm 52 is arranged so as to connect the support leg 50 and the base 16 of the child seat 12, and thus is unrelated to the vehicle seat 34. Is disposed outside the vehicle seat 34. In addition, since the support leg 50 and the support arm 52 of the child seat support device 10 according to the present embodiment are both long members, they can be installed in a small space. From these facts, according to the present embodiment, the child seat support device 1
0 can be reduced in installation space.

Further, in the child seat support device 10 according to the present embodiment, the upper end of the support leg 50 is foldably connected to the front end of the support arm 52, so that when the child seat 12 is packed and transported, the child seat is supported. The device 10 can be folded. Therefore, according to the present embodiment, the child seat support device 1
0 can be improved in packing and transportability.

In the child seat support device 10 according to the present embodiment, the support leg 50 includes the holder 56 and the slider 54, and the height of the support leg 50 can be adjusted. The child seat support device 10 can be mounted on the child seat 12 in this manner.

In the present embodiment described above, the vehicle seat 3
Although the description has been made by taking as an example a configuration in which the base 16 of the child seat 12 is fixed using the seat belt device 44 provided for the vehicle 4, the child seat is fixed to the vehicle seat by a configuration other than the seat belt device. The present invention is applicable to such a configuration.

FIG. 5 shows an example of this, which will be briefly described below. As shown in this figure, a pair of elongated connectors 92 extend from both sides of the rear end of the base 16 placed on the vehicle seat 34 toward the vehicle rear side. A locking groove 94 for engagement is provided at the rear end of the connector 92.
The lock means including a latch (not shown) is provided at the position where the lock groove 94 is formed. On the other hand, an anchor member 98 is fixed to the body 96 with bolts 99, and the distal end of the anchor member 98 is relatively inserted into the lock groove 94 of the connector 92, so that the connector 92 is connected to the anchor member 98. The rear ends are connected and locked. With such a connector type configuration, the base 16 of the child seat 12 is provided.
Is fixed to the vehicle seat 34, the child seat support device 10 according to the present embodiment is properly mounted and effectively exerts its function.

Note that the seat belt device 44 and the connector 92 are elements that are grasped as "child seat fixing means" in a broad sense.

Further, in the above-described embodiment, the child seat support device 10 is configured to be foldable. However, the child seat support device may be further stored and stored in the base when not in use.

FIG. 6 shows an example of this, which will be briefly described below. As shown in FIG.

A detent mechanism, a lock mechanism, and the like (not shown) are provided between the support arm portion 02 and the support arm portion 52 so that the support arm portion 52 does not slide along the guide rail 102 carelessly.

According to the above configuration, the child seat support device 10 is stored in the base 16 as follows. The state shown by the two-dot chain line in FIG. 6 is the use state of the child seat support device 10. From this state, first, the bolt 66 is loosened, and the slider 54 is slid toward the holder 56. Then, with the support leg 50 contracted most,
The bolt 66 is screwed into the fixing hole 64 and temporarily fixed. Next, when the support leg 50 is to be folded toward the support arm 52 as it is, the lower end of the support leg 50 interferes with the seat cushion 36 of the vehicle seat 34 or the like. Therefore,
The support arm 52 is once pulled out of the base 16 to the front of the vehicle to such an extent that the interference can be avoided. Next, the lock state is released by sliding the slide button 82 in the release direction, and the support leg 50 in which the holder 56 and the slider 54 are overlapped is rotated around the shaft 76 to be folded (the state shown by a dashed line). Thereafter, the folded child seat support device 10 is slid rearward of the vehicle along the guide rail 102 to be stored in the storage space 100 provided on the bottom surface side of the base 16.

With this configuration, when the child seat 12 is fixed to or removed from the vehicle seat 34, the child seat support device 10 does not become a hindrance, and when the child seat support device 10 is not used. The appearance quality of the child seat 12 can be improved.

In the above configuration, the support arm 5
A biasing means (a compression coil spring or the like) for pulling and biasing the second member 2 along the guide rail 102 in the storage direction may be further added.

Various storage structures other than the above-described configuration can be applied. For example, the sliding structure of the slider 54 and the holder 56 adopted in this embodiment is
By applying the same method to the two sides, the child seat support device may be stored in the base.

(3) Further, in the above-described embodiment,
Although the "height adjustment mechanism" of the present invention is configured by the slider 54, the holder 56, the plurality of fixing holes 64, and the bolts 66, the concept of the "height adjustment mechanism" includes various configurations other than the above configuration. For example, a rack and pinion type mechanism, a pantograph type mechanism, or the like may be applied.

(4) In the above-described embodiment, the support arm 52 and the holder 56 are connected to each other by the shaft 76 so as to be rotatable relative to each other. Any configuration that can be grasped as "connection means" can be applied. For example, it is also possible to adopt a configuration in which hinges are connected using rivets.

(5) Further, in the above-described embodiment,
Although the slide button 82 is used not only as the "release means" but also as a component of the "lock means", a configuration in which the lock means and the release means are clearly separated may be employed. The concept of the "lock means" in the present invention includes various configurations. For example, if the configuration of the present embodiment described above is utilized, a configuration in which another spring such as a tension coil spring may be used instead of the compression coil spring 88 which is grasped as “biasing means” in a broad sense may be adopted. . When a tension coil spring is used, the position of the spring locking portion 84 may be changed so that the biasing relationship is reversed. In addition, "lock means"
The concept of also includes a simpler configuration. For example, it is the same as the present embodiment up to the point where the holder 56 and the support arm 52 are connected by the shaft 76, and a stand in which a bar-shaped member is formed into a right triangle between the holder 56 and the support arm 52 is rotatable. Even if they are attached, the relative rotation between them is restricted, so that they function as locking means.

(6) Further, a plurality of the child seat supporting devices 10 according to the present embodiment may be used. If a plurality of child seat supporting devices 10 are used, the supporting state of the child seat 10 can be stabilized accordingly.

(7) In the above-described embodiment, an example in which the child seat 12 is constituted by the child seat main body 14 and the base 16 is used. However, the present invention is not limited to this, and a child seat of a type in which both are integrated is used. The present invention is also applicable to
