Description

[Detailed Description of the Invention] The present invention relates to a child seat for a vehicle, and particularly to a child seat equipped with a body restraint frame.

Generally, when seating an infant in a vehicle seat, a child seat is attached to the vehicle seat, and the infant is seated in the child seat. However, the drawback was that when the child seat was not in use, it was difficult to store it. Furthermore, in the case of a simple child seat, there is a risk that the child may fall due to the vehicle's rolling or braking. In order to deal with this, as shown in FIG.
It has been proposed that a substantially U-shaped body restraint frame 2 constituting the outer periphery of the child is rotatably attached to the seat back part 1 with a shaft 3 to restrain an infant. However, with only the body restraint frame 2, the height of the seat cushion portion 4 is constant, which has the disadvantage that it does not suit the body shape of the infant. Furthermore, even if the body restraint frame and the child seat are combined, the height cannot be adjusted, so there is still a drawback that it cannot be made suitable for young children.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a child seat for a vehicle in which a seating portion is provided in a body restraint frame in order to eliminate the conventional drawbacks.

The present invention will be described in detail below based on embodiments shown in the drawings.

2 to 7 are diagrams showing an embodiment of the vehicle child seat 5 according to the present invention. In the figure, the vehicle seat has a seat cushion part 6.
, a seat back portion 7 , and a safety pillow 8 .
The vehicle child seat 5 has a body restraint frame 9. The body restraint frame 9 is formed into a U-shape by a pair of leg parts 10 and 11 forming the left and right outer peripheries of the seat back part 7, and a horizontal part 12 forming the upper outer periphery of the seat back part 7. The legs 10 and 11 of the body restraint frame 9 are the shaft 1
3, it is rotatably attached near the center of the side surface of the seat back portion 7. A hole 15 is formed in the horizontal portion 12 to receive the stay 14 of the safety pillow 8. The take-up lock mechanism is shown in FIGS. 4-6. A shaft 16 is fixed to one leg 10 of the body restraint frame 9. A winding roller 17 is pivotally supported inside the other leg portion 11 . One end of a wide belt-shaped seat 18 made of a soft sheet or cloth is attached to the shaft 16 through a not-shown slit in the leg 10, and the other end is attached to the winding roller 17 through a not-shown slit in the leg 11. installed on. The seating portion 18 constitutes a child seat, and an infant can sit in the center of the seating portion 18. When the body restraint frame 9 is rotated toward the seat back section 7, the seating section 18 is pulled out from the winding roller 17 by the amount that almost matches the shape of the surface of the seat back section 7 and comes into contact with it, and the rest of the seating section 18 is pulled out from the winding roller 17. It is wound up in 17. The tip of the winding roller 17 has a small diameter, and the fixing plate 20 is inserted through it. A spring 19 is interposed between the step portion 21 between the main body and the tip of the winding roller 17 and the fixed plate 20, and constantly urges the winding roller 17 toward the horizontal portion 12. A ratchet 22 is attached to the horizontal portion 12 side of the winding roller 17. The winding roller 17 is connected to the horizontal portion 1 from the outside of the horizontal portion 12.
An operation dial 23 is provided that penetrates into the inside of 2. A locking pin 24 is provided within the horizontal portion 12 and engages with the ratchet 22. The lock pin 24 rotates the ratchet 22 toward the leg 11 by rotating the operation dial 23 clockwise in the drawing, that is, toward the leg 11 of the body restraint frame 9. Lock pin 24 is ratchet 2
2 is prevented from rotating counterclockwise in the drawing, that is, toward the leg portion 10.

In the embodiment configured as described above, in order to use it as a child seat, the safety pillow 8 is removed and the body restraint frame 9 is rotated from the seat back portion 7 toward the seat cushion portion 6 to be positioned horizontally.
Next, turn the operation dial 23 clockwise, that is, on the leg 1.
When turned toward the 1 side, the ratchet 22 acts on the lock pin 24 and rotates in the same direction, and at the same time the winding roller 17 also rotates in the same direction, and the belt-shaped seating portion 1
8 toward the winding roller 17 side. The ratchet 22 is prevented from rotating counterclockwise in the drawing, that is, toward the side of the leg 10, by a locking pin 24. The lock pin 24 is prevented from rotating more than necessary toward the leg portion 10 by a stopper (not shown). The stay 14 of the safety pillow 8 is inserted into the hole in the seat back part 7, and the height of the seat part 18 is set by rotating the operating dial 23 to a height suitable for the infant to sit on. The child enters the body restraint frame 9 and sits in the center of the seating section 18 whose height is adjusted to suit the child's body shape, thereby making the child seat 5 suitable for the child's body shape. Can be done. When the child seat 5 is not in use, press the operation dial 23 to release the winding roller 1.
7 presses the spring 19 and moves in the axial direction. At this time, the ratchet 22 moves to the position indicated by the dotted line in FIG.
7 is allowed to rotate counterclockwise, that is, toward the leg 10. When the body restraint frame 9 is rotated toward the seat back part 7, the seat part 18 is rolled up to the extent that the seat part 18 can contact the uneven surface of the seat back part 7 by covering it from the upright body restraint frame. It is pulled out from the roller 17, and the remaining portion of the seating portion 18 is wound up by the winding roller 17.
The safety pillow 8 is removed from the seat back part 7, the body restraint frame 9 is rotated toward the seat back part 7, and the stay 14 of the safety pillow 8 is inserted into the hole 15. This allows the child seat to be stored and used as a normal adult seat.

As explained above, according to the present invention, by providing a seat made of a soft sheet that is attached between both legs of the body restraint frame and whose drawer length can be adjusted by a winding lock mechanism, it is possible to The child seat can be set at a height that suits your body shape. Therefore, while the vehicle is running, the infant can see the outside scenery, so there is no need to worry about standing up, and there is no risk of the infant falling over due to the rolling of the vehicle, braking, etc., making it safer. When the child seat is not in use, move the body restraint frame 9 to the seat back part 7.
To prevent the seating part 18 from getting caught on the seat back part 7 when the seat is raised to the side, and by pulling out the seating part 18 from the roll-up rollers 17 to a certain extent so as not to get in the way, the seating part 18 can be moved along the front surface of the seat back part 7. Since the child seat is in contact with the seat, the child seat is stored, and there is no need to worry about storage space as in the past.Furthermore, the soft sheet that makes up the seating section 18 acts as a seat cover, so the child seat can be stored without getting in the way. It does not spoil the appearance. Further, as shown by the dashed line in FIG. 7, it is possible to prevent the infant's legs from flying out laterally.
