BRIEF DESCRIPTION OF THE DRAWINGS FIG. In the figure, reference numeral 1 denotes a seat back of a rear seat, 2 denotes a concave portion for fitting a cushion body formed on the surface of the seat back 1 in a vertical direction, 3 denotes a back cushion plate 3a and a front cushion plate 3b housed in the concave portion 2. The back cushion plate 3a and the front cushion plate 3b have a large shape each having substantially the same area as the recess 2.

As shown in FIG. 4, the cushion body 3 is provided on a plate member 5a for a seating surface and a plate member 5b for a backrest surface which are connected at the center by a hinge 4 so as to be able to bend vertically. Attach the member, back cushion plate
The front cushion plate 3b is formed so as to take two modes, that is, a state in which the outer surface of the front cushion plate 3b and the inner surface of the front cushion plate 3b face each other so as to face each other, and a state in which the front cushion plate 3b is folded and unfolded and deployed. They are connected at the upper end. As shown in FIG. 2, the lower end portion of the cushion body 3 is formed so that when the cushion body 3 is pulled forward from the seat back 1, the infant seat is formed to face backward, that is, a seating posture toward the seat back 1. Are pivotally attached to the lower portion of the seat back 1 by hinges 6. Further, a suspension band 7a is stretched between the middle portions on both sides of the front cushion plate 3b of the cushion body 3 and the seat back 1, and between the middle portions on both sides of the back cushion plate 3a and the front cushion plate 3b. When the cushion body 3 has a seat-chair-like shape with a band 7b for holding the backrest part stretched, the seat back 1
, A seating posture at a predetermined angle can be ensured. Since the back cushion plate 3a does not need to have cushioning properties when housed in the recess 2, the back cushion plate 3a is held upright from the front end of the front cushion plate 3b that has been moved forward to form a seat back for infant seating. It is sufficient that only one side is a cushion surface, but the front side cushion plate
3b is preferably a cushion surface on both sides since the front surface becomes a back surface of the seat back when it is stored in the concave portion 2 and the rear surface becomes a seat receiving surface of a seat cushion for infant sitting when it is folded forward.

The cushion body 3 is provided with a fixing belt 8 for fixing the seat when used as an infant seat, and connects the back cushion plate 3a to the vehicle body base member. This prevents the infant seat from lifting up. In addition, a seat belt 9 for securely holding the infant when used as an infant seat is naturally provided. In addition,
In the embodiment, the cushion body 3 is a front side cushion plate 3b.
And a suspension band 7a stretched between the seat back 1 and
While the back cushion plate 3a and the back cushion plate 3b are stretched between the back cushion plate 3a and the front cushion plate 3b, they are held in a seat-chair shape, but the hinge 4 and the hinge 6 are held at a predetermined angle. A mechanism that can be held in a state of being bent into a chair or a state in which it is bent into a chair by using such a hinge mechanism in combination with the band as described above. It is optional to change the design in details such as

[0010] The front cushion plate thus constructed is normally housed in the recess 2 in a superposed state.
3b and the back side cushion plate 3a are buried in a cushion body 3 which is superimposed and have the same appearance as a normal vehicle seat and are used as seats for general adults.
When an infant is to be seated, the upper end of the cushion body 3 in the concave portion 2 of the seat back 1 is pulled forward to lower the front side cushion plate 3b as shown in FIG. 3, and pivot on the upper end of the front side cushion plate 3b. When the back cushion plate 3a being worn is erected substantially at right angles to the front cushion plate 3b, the cushion body 3 can be used as an infant seat cushion above the seat cushion 1 as a back cushion plate. The back cushion plate 3a, which is a seat-chair having the seat back 3a as a seat back for infant seating, and the front cushion plate 3b, which is a seat back for infant seating, and a front side cushion plate 3b, which is a seat cushion for infant seating, are respectively bands for suspension and holding.
A rearward-facing infant seat is suspended and held by the backrest 7a and the backrest-holding band 7b so that the backrest and the seating portion maintain a seating posture at a predetermined angle with respect to the seatback 1.

The infant sheet thus obtained is
Since the infant is seated backward and used, the person sitting on the seat back 1 and the infant face each other, so that the infant's appearance can be clearly understood, and a collision accident or the like may occur. In addition, the impact on the infant's neck due to the impact load is extremely small, and excellent safety is exhibited. In addition, the back cushion plate constituting the backrest for infant seating
The strips 7a and 7b on both sides of the front side cushion plate 3b, which constitutes the seating surface 3a and the infant's seating surface, prevent the infant from shifting to both sides. It will be. Further, a cushion member having a sufficient thickness is stuck on the seating surface side of the infant seat, so that excellent sitting comfort can be exhibited. On the other hand, even when the cushion body 3 is stored in the seat back 1, it is sufficient. Needless to say, the cushion member having an appropriate thickness acts so as not to impair the feeling of use as a seat. Further, since the back cushion plate 3a and the front cushion plate 3b each have a large shape having the same area as the concave portion 2 provided in the seat back 1, it is suitable for children of all types from small children to large children. All can be perfectly adapted, greatly expanding the scope of application.

[0012]

[Effects of the Invention] As is clear from the above description, the present invention can be used by ordinary adults usually sitting on the seat, but can be easily switched to the infant seat with one touch if necessary. In addition, the infant can be seated backward, minimizing the burden on the neck of the infant due to the impact load in the event of a collision, and exhibiting excellent safety, and is perfectly suitable for children of different body types That can be done. Therefore, the present invention has a very large practical value as a vehicle seat that can be switched to an infant seat that has eliminated the conventional problems.
