In the projecting state, the tip end of this lock pin 152 is a through hole. The seat body 12 and the buggy car 100 are fixed by being inserted into 118C. It should be noted that the lock pin 152 has a moderation degree and is lightly held in a state in which it is projected to the passage interval 72 and a state in which it is retracted from the projection, so that the user can easily operate it.

As shown in FIGS. 8 and 17, the mounting block 124 is formed with an inclined surface 124A which is close to the peripheral edge of the seat body 12 when the seat body 12 is securely attached to the buggy car 100. A colored tape 157 that constitutes a confirmation mark is attached. The coloring tape 157 is applied to the buggy car 100 and the seat body 12
Is securely attached, and is covered by the edge of the sheet body 12, and if not securely attached, the colored tape 157 is not hidden by the edge and is visible, so that the user is not sure. The mounting state can be determined.

(Operation of Embodiment) The seat body 12 is attached to the buggy car 1 from the mounted state on the vehicle shown in FIGS.
In order to move the tongue plate 00, the release button 32A of the buckle 32 is pressed to disengage the tongue plate 34 from the buckle 32. As a result, the shoulder belt 36 and the waist belt 38 can be removed from the state in which they are wound around the seat body 12. Here, the seat body 12 holds the edge portion 12A of the seat body 12 or pulls out the intermediate portion of the carrying rope 46 to the imaginary line state of FIG. Can be carried while being restrained with. As shown in FIG. 10, the roller 64 at the front end portion of the seat body 12 is moved into the U-shaped recess 110A of the lower support block 110, and the support projection of the upper support block 118 is provided in the passage space 72 between the bracket 56 and the bracket 58. By supporting the inside of the portion 118A, the supporting state shown in FIG. 9 is obtained.

In this case, the roller 64 is the U-shaped recess 11 directly.
Although it may be inserted into 0A, it is temporarily mounted on the inclined portion 110B, and in this state, the extension portion 68 of the slide protrusion 68 is
A is a receiving surface 118F that is the upper end of the support protrusion 118A.
Place it on. By this placing operation, the seat body 12
Since the weights of the rollers are temporarily supported by the lower support block 110 and the upper support block 118, respectively, the user keeps the load supporting state while the roller 64 is inclined 110.
Roller 64 is guided to the U-shaped recess 110A while rolling, and the extension portion 68A is moved in the direction of arrow D while guiding the receiving surface 118F of the support protrusion 118A, whereby the roller 64 is moved to the bottom of the U-shaped recess 110A. Corresponding to, the passing interval 72 is in a state of accommodating the support protrusion 118A.

As a result, the roller 64 is only allowed to move in the direction opposite to the arrow A direction, and the brackets 56 and 58 are only allowed to move in the direction opposite to the arrow D direction. Normal buggy car 10
Such a load in the direction of lifting the seat body 12 is not applied depending on the movement operation of 0, and the child occupant seat 10 is reliably supported by the buggy car 100. Further, when the buggy car 100 suddenly stops during movement, a load acts on the seat body 12 in a crossing direction (direction of arrow E in FIG. 1) substantially orthogonal to the direction of arrow D about the roller 64, This load is such that the locking protrusion 70 corresponds to the bottom surface 118G of the upper support block 118 and the lower support block 10.
Since the child vehicle seat 10 is supported at 0, the child vehicle seat 10 does not come off from the lower support block 100.

By further operating the knob 154 shown in FIG. 3 to cause the lock pin 152 to project from the passage interval 72 and to be inserted into the through hole 118C of the upper support block 118, the child vehicle seat 10 is Movement in the direction opposite to the direction of arrow A in FIG. 2 and in the direction opposite to the direction of arrow D in FIG. 1 is also prevented, so that a reliable fixed state is achieved.

As described above, in the state in which the roller 64 is inserted into the bottom of the U-shaped recess 110A and the support projection 118A does not correspond to the passage gap 72, the child occupant seat 10 is edged as shown by an imaginary line in FIG. Since the upper end of the portion 12A is placed away from the coloring tape 157 and the coloring tape 157 is visible, the user can easily determine that the supporting state is not reliable. In addition to the colored tape 157, another warning display means such as a dial is provided on the slope 124.
It is attached to a part of the buggy car 100 such as A, or the display means for alerting such coloring, letters, unevenness, etc. is directly attached to a part of the buggy car 100 by hot stamping, printing, spraying or the like. May be.

FIG. 18 shows a state in which a child occupant seat 200 of another type is attached in place of the child occupant seat 10. This child occupant seat 200 is for accommodating a child occupant aged older than the child occupant seat 10, and is basically the same as the child occupant seat 10 in that the child occupant is accommodated and restrained with a seat belt. It is the same.
Further, the child passenger seat 200 is different in that the lock pin 152 of the seat body 12 in FIG. 3 is always urged by an elastic body urging force such as a spring in a protruding direction toward the passage interval 72 so that it is always in a protruding state. . Further, in the child occupant seat 200, the bracket 56, the slide projection 68 of the bracket 58, and the locking projection 70 are omitted. Therefore, in this child occupant seat 200, when the lock pin 152 is slid in the direction of arrow F or in the direction of arrow G when the lock pin 152 is attached to the upper support block 118 of FIG. The inclined surface receives the pushing force, and is pulled into the bracket 56 and the bracket 58 against the biasing force. When the lock pin 152 moves to the position corresponding to the through hole 118C, the lock pin 152 projects again by the urging force and is inserted into the through hole 118C, and a secure fixing state is achieved.

In the above embodiment, the roller 64 and the slide projection 68 make the weight of the seat body 12 self-weight.
The seat body 12 is supported by the buggy car 100 at a portion other than these portions. The seat body 12 may be supported only when an inadvertent load such as detachment is applied. Also, the U into which the roller 64 is inserted
The U-shaped recess 110A does not necessarily have to be U-shaped, and other recessed shapes such as V-shaped, U-shaped, and dish-shaped can be widely applied as long as the roller 64 can be received. Further, the lock pin 152 in the above embodiment may be provided as necessary, and may be omitted when the seat body 12 is securely attached to the buggy car 100 by other components. Also, this lock pin 152
In addition to the above, other locking means such as a cam, a screw, and a lock lever can be applied to securely fix the seat body 12 to a buggy car or the like.

Further, although the above embodiment has described the support structure for attaching the child occupant seat 10 to the buggy car 100, the present invention may be applied to other supporting members provided in the vehicle or other places. It is widely applicable to support, and in this case, a component having the same function as the lower support block 110 and the upper support block 118 provided in the buggy car 100 may be provided in advance on this support member.
