FIG. 4 is a perspective view from the back side of the child seat and an explanatory view of the stopper, FIG. 5 is a front view of the backrest portion of the child seat, and FIG. 6 is a rear view of the backrest portion.

  As shown in FIGS. 1 and 2, the child seat according to the first embodiment includes a seating surface portion 10 of an air cushion structure, a clothes-type backrest portion 20 also serving as a fixing portion, and a crotch type combined with the backrest portion 20. And a fixed belt 30.

  As shown in FIGS. 3 and 4, the seat surface portion 10 includes a main body portion 11 that mainly receives the weight of a child, a pair of first holding portions 12 and 12 that are raised upward from both side portions of the main body portion 11, and a main body It consists of a relatively thin second holding part 13 that extends upward from the end on the back side of the part 11, and is formed so as to wrap the child's waist from three sides. These parts are formed by an integrally formed airtight bag body, and are inflated as shown in the figure by injecting air from an air inlet 14 provided on the front surface of the main body 11. Form an air cushion in shape. A fastener 16 is attached to the upper edge portion of the second holding portion 13 for connection with the backrest portion 20.

  The clothes-type backrest 20 has a front-opening best form. The backrest portion 20 is separable from the seat surface portion 10, and is integrated with the seat surface portion 10 by joining a fastener 21 attached to the back portion of the backrest portion 20 to the fastener 16 of the seat surface portion 10. The fastener 21 is provided slightly above the lower end of the backrest 20. Thereby, the lower part of the backrest part 20 overlaps the front side of the second holding part 13 of the seat surface part 10.

  As shown in FIGS. 5 and 6, the vest-type backrest 20 has dimension adjustment belts 22 on both shoulders. An air cushion 23 is attached to the portion of the backrest 20 from both shoulders to the back. The air cushion 23 also serves as a fixing mechanism for the seat of the automobile. That is, the seat belt 100 of the automobile is passed between the main body of the backrest portion 20 and the air cushion 23, and the lateral belt portion of the seatbelt 100 is placed on the backrest portions on both sides of the air cushion 23 by the pair of stoppers 110 and 110. The child seat is fixed to the seat of the automobile by being fixed to the main body 20. The stoppers 110 and 110 have, for example, a hairpin shape, and are fixed to the lateral belt portion of the seat belt 100 on the main body by being inserted into the main body of the backrest portion 20.

A fixing belt 30 is attached to the backrest 20 and air is also injected into the air cushion 23. In this state, the child seat is attached and fixed to the seat of the automobile using the seat belt 100 and the stoppers 110 and 110. The air may be injected by an air pump using a car cigarette lighter as a power source.

  Since the child seat does not use a resin or metal frame, it is lightweight and can be deformed even when air is injected into the seat surface portion 10 and the air cushion 23. For this reason, the installation work to a seat is easy.

  A child is seated on a seat surface portion 10 of a child seat attached to a seat of an automobile, the child is dressed with a backrest portion 20 of the best type, and a fixing belt 30 is attached. Thereby, the child is fixed to the child seat. It is also possible to attach the backrest 20 to the seat surface 10 before connecting it to the seat surface 10 and then connect the backrest 20 to the seat surface 10.

  The child seat itself has a fixing function for the child, and also exhibits the fixing function for the child by fixing the fixing belt 30. As a result, the child is securely fixed to the child seat. Further, since the main body of the backrest portion 20 of the child seat is fixed to the seat of the automobile, the main body of the backrest portion 20 is prevented from being tilted forward when subjected to an impact.

  In addition, the child does not sit directly on the seat of the automobile, but sits on the seat surface portion 10. This raises the eyes of the child and removes the feeling of obstruction, so that discomfort is greatly relieved compared to sitting directly on the seat. Since the seat surface portion 10 itself has a cushion function, the seating comfort is good without attaching the cushion. In addition, by providing the back cushion 20 with the air cushion 23, the sitting comfort is further improved, and the impact mitigating effect at the time of collision, particularly the effect of protecting the child's clavicle is increased.

  If air is let out from the air cushion 23 of the seat surface portion 10 and the backrest portion 20, the child seat loses rigidity and returns to its original flexible state. For this reason, it can be folded small, which facilitates storage and transportation. That is, as shown in FIG. 20, the charide sheet from which the air has been removed may be placed in a special bag 200. In FIG. 20, reference numeral 210 denotes an air pump housing for inflating the air cushion 23.

  Thus, although the child seat which concerns on 1st Embodiment made the seat surface part 10 and the backrest part 20 into the flexible structure which is easy to carry and store, it can make a child sit in a high position, The child Discomfort can be greatly reduced.

  The backrest 20 also serves as a fixing mechanism for the child. For this reason, it is relatively compact.

  FIG. 7 is a front view of another backrest portion, and FIG. 8 is a rear view of the backrest portion.

  The backrest 20 shown in FIGS. 7 and 8 differs from the backrest 20 described above in that a pants-type fixing part 40 is combined instead of the fixing belt 30. The pants-type fixing portion 40 is integrated with the vest-type backrest portion 20 by a fastener 41. A waist belt 42 is attached to the fixed portion 40. Other configurations are the same as those of the backrest portion 20 described above, and the same portions are denoted by the same reference numerals and description thereof is omitted.

  This backrest part 20 also securely fixes the child on the seat surface part 10, and the cushion 23 ensures high comfort and safety. Further, by serving also as a fixing mechanism, the structure is simplified and the size can be reduced.

  The child seat according to the fourth embodiment can fix the child more reliably by combining the vest type fixing portion 80 and the crotch type fixing belt 30. The effect of this combination is as described in the first embodiment.

  FIG. 18 is an explanatory view of the structure and usage state of a child seat according to the fifth embodiment of the present invention.

  The child seat according to the fifth embodiment is a simplified type obtained by simplifying the child seat according to the third embodiment, and the structure of the airtight bag body 70 and the structure of the fixing belt 50 attached thereto are slightly different.

  That is, the airtight bag 70 has a structure in which seam portions are provided vertically and horizontally like an air mat. Further, the fixed belt 50 is changed from a five-point support type to a three-point support type.

  By injecting air into the airtight bag body 70, a mat-like air cushion is formed, and using a seat belt, it is bent along its seating surface and backrest by attaching it to a car seat, The formation of the seat surface portion 10 and the backrest portion 20 is the same as the child seat according to the third embodiment. Moreover, the fixing method to the seat of a motor vehicle is the same as the child seat which concerns on 3rd Embodiment.

  Although the child seat according to the fifth embodiment is a simple type, the child can be seated at a high position by the seat surface portion 10. Further, since the seat surface portion 10 and the backrest portion 20 have an air cushion structure, the seating comfort is good, and since it is lightweight and can be deformed even when air is injected, the mounting operation is easy. Moreover, if air is let out from the seat surface part 10 and the backrest part 20, it will return to the original flexible state, and since it can be folded small in a roll shape, storage and transportation are also easy. Furthermore, the child is securely fixed via the fixing belt 50, and the safety is excellent.

  FIG. 19 is an explanatory view of the structure and usage state of a child seat according to the sixth embodiment of the present invention.

  The child seat according to the sixth embodiment is formed by integrally forming a fixed portion having an air cushion structure as a whole in a vest form on the portion that becomes the backrest portion 20 of the air mat-shaped bag body 70, and omitting the fixing belt 50. This is different from the child seat according to the fifth embodiment.

  This child seat is a further simplification of the child seat according to the fifth embodiment, but the child is effectively fixed and protected as if wearing a life jacket.

  FIG. 21 is a cross-sectional view of a seat surface portion of a child seat according to the seventh embodiment of the present invention.

  In the child seats according to the first to sixth embodiments, air is injected into a portion that becomes an air cushion. However, in the child seat according to the seventh embodiment, air is not injected but air is automatically injected. It was made to suck.

  That is, as shown in FIG. 12, a space containing air such as urethane is formed inside, and a material 90 having a characteristic of expanding toward the outside when being compressed is filled. For example, if the material 90 is filled in the seating surface portion 10, the material 90 may spread outward when an air suction port (not shown) (equivalent to the air injection port 14 in the above-described embodiment) is opened. The seating surface portion 10 automatically swells with the force to be generated, and at the same time, air is sucked into the seating surface portion 10. When the air suction port is closed with the material 90 inflated, the seat surface portion 10 is formed.

  The seat surface portion 10 formed in this way has a smaller amount of air to be filled than the air-injecting type, and therefore deforms along the body shape of the sitting child to protect the child. Further, before closing the air suction port, air is forcibly injected into the inside of the seat surface portion 10%, which is the same as that for injecting air. However, in this case, since most of the air is sucked and filled in the seat surface portion 10, the amount of forcedly injected air is reduced, and there is an effect that the air can be easily injected.

  Thus, while the space including air such as urethane is formed and the material 90 having the characteristic of expanding toward the outside when being compressed, the seat surface portion 10 is filled, the seat surface portion Needless to say, not only 10 but also the backrest 20 is filled.

  Next, an eighth embodiment of the present invention will be described with reference to FIGS. 22 to 25 show an eighth embodiment of the present invention, FIG. 22 is a perspective view showing a usage state of the child seat according to the eighth embodiment, and FIG. 23 is a perspective view of the child seat according to the eighth embodiment in an opened state.
