[Industrial applications]

 The present invention relates to a vehicle seat that uses a part of a seat back and can be switched to an infant seat that is highly safe and provides a rearward sitting posture with a simple operation only when necessary.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, for vehicle seats such as automobiles, various special safety seats for infants called "child seats" have been proposed in order to safely hold small infants. As disclosed in Japanese Laid-Open Patent Application No.-91730, Japanese Utility Model Laid-Open No. 62-135651, etc., the infant is directed backwards toward the seat back in order to minimize the burden on the infant's neck due to the impact load in a collision accident. There have been proposals for devices designed to take a sitting posture.

However, since all of the conventional child seats that have such a rearward sitting posture have a structure for use only for children, once the child seat is attached, regardless of whether it is used or not. There was a problem that the child seat was always installed, making the seat space small and making the seat inconvenient. Therefore, the applicant takes two modes, that is, a state in which the upper cushion body and the lower cushion body are in an expanded state and a state in which they are folded into a chair-like shape in a recess for fitting the cushion body formed on the surface of the seat back. I devised a vehicle seat that accommodates a cushion body connected to the above and applied for it as Japanese Patent Application No. 4-52249, but the problem is that it cannot be perfectly adapted to children of various sizes. Was left.

[0004]

[Problems to be solved by the device]

 The present invention solves the above-mentioned conventional problems, and can be used by ordinary adults while sitting, while it can be easily switched to the infant seat with one touch if necessary, and The infant can be seated backwards, which minimizes the burden on the infant's neck due to the impact load in a collision accident and provides excellent safety, and is perfectly adapted to children of different body types. It was completed for the purpose of providing a vehicle seat that can be switched to a child seat that can be used.

[0005]

[Means for Solving the Problems]

 A vehicle seat with an infant seat of the present invention made to solve the above-mentioned problems is provided with a cushion body in which a cushion body fitting recess is formed on the surface of a seat back, and the cushion body is switchable to the infant seat in the recess. In a vehicle seat that can be switched to an infant seat, the cushion body is placed in a normal state in which the lower end is pivotally attached to the lower part of the recess and the opening end of the recess is filled, and the cushion body is tilted above the seat cushion. A front cushion plate that can be switched between two modes of forming a seat cushion for seating an infant, a normal state in which the seat cushion is folded backward from the upper end of the front cushion plate in the recess, and a standing state is held from the front end of the front cushion plate that is folded forward. And a back cushion plate that can be switched between two modes of forming a seat back for seating an infant. Is shall.

[0006]

[Action]

 In such a structure, the outer appearance is similar to that of a normal vehicle seat when it is normally embedded in a cushion body composed of a front cushion plate and a back cushion plate that are accommodated in the recess as a stack. However, when seating an infant, pull the upper end of the cushion body in the recess of the seat back forward to tilt the front cushion plate forward and If the back cushion plate pivotally attached to the upper end of the cushion plate stands up at a substantially right angle with respect to the front cushion plate, the cushion body is located above the seat cushion, and the front cushion plate is seated on the infant cushion. With the back cushion plate as a seat back for infant seating, it becomes a rear-facing infant seat that is held like a chair, and the infant faces forward. On top that can be seated in rear-facing that can face the person who is sitting, so that the safety of the superior will be minimized burden on the infant's neck portion due to the impact load at the time of collision accident can be exhibited.

【Example】

 The present invention will now be described in detail with reference to the illustrated embodiment. In the figure, 1 is a seat back of a rear seat, 2 is a recess for vertically fitting a cushion body formed on the surface of the seat back 1, 3 is a back cushion plate 3a and a front cushion plate 3b housed in the recess 2. The back cushion plate 3a and the front cushion plate 3b are large-sized ones having substantially the same area as the recess 2.

As shown in FIG. 4, the cushion body 3 is mounted on a plate body 5a for a seating surface and a plate body 5b for a backrest surface, which are connected to each other by a hinge 4 so as to be bendable in the vertical direction. With the cushion member attached, the back cushion plate 3a is folded and stored backwards so that the outer surface of the back cushion plate 3a and the inner surface of the front cushion plate 3b face each other, and a state of being folded into a chair and unfolded. The front side cushion plate 3b is connected to the upper end portion so as to take two modes. As shown in FIG. 2, the cushion body 3 has a lower end portion so that when the seat cushion 1 is pulled out from the seat back 1 in a forward direction, a seat for a baby is formed in a rearward direction, that is, a seated posture toward the seat back 1. Is hinged to the lower part of the seat back 1 by a hinge 6. A suspension belt 7a is stretched between the seat back 1 and the intermediate portions on both sides of the front cushion plate 3b of the cushion body 3, and between the intermediate portions on both sides of the back cushion plate 3a and the front cushion plate 3b. In addition, a belt 7b for holding the backrest is stretched so that the seatback 1 can be seated at a predetermined angle when the cushion 3 is in the form of a chair. The back cushion plate 3a does not need to have cushioning properties when it is stored in the recess 2. Therefore, the back cushion plate 3a is erected from the front end of the front cushion plate 3b which is tilted forward to form a seat back for seating an infant. Only one side of the seat cushion should be the cushion surface, but when the front cushion plate 3b is stored in the recess 2, the front surface becomes the seat back seat back surface, and when it is tilted forward, the rear surface is the seat cushion for infant seating. Since it becomes the seat receiving surface, it is preferable that both surfaces are cushion surfaces.

Further, the cushion body 3 is provided with a fixing belt 8 for fixing the seat when it is used as an infant seat, and connects the back cushion plate 3a and the vehicle body base member. By doing so, the lifting of the infant seat is prevented. In addition, a seat belt 9 for safely holding the infant when it is used as a child seat is naturally provided. In addition, in the embodiment, the cushion body 3 is stretched between the front cushion plate 3b and the seat back 1 for suspension, and the backrest stretched between the back cushion plate 3a and the front cushion plate 3b. Although it is designed to be held in a chair-like shape with the band member 7b for holding the part, it can be bent into a chair-like shape by providing the hinge 4 and the hinge 6 as a mechanism capable of holding them at a predetermined angle. It is possible to change the design in detail, such as keeping it in a seated state by using such a hinge mechanism and the band as described above in combination. Is.

In such a structure, a cushioning body 3 in which a front side cushion plate 3b and a back side cushion plate 3a, which are normally stored in the recess 2 in a stacked state, are embedded is embedded in a normal vehicle. The seat has the same appearance as a seat for adults and is used as a seat for general adults, but when an infant is to be seated, the upper end of the cushion body 3 in the recess 2 of the seat back 1 is pulled forward and the seat shown in FIG. If the front cushion plate 3b is tilted forward and the back cushion plate 3a pivotally attached to the upper end of the front cushion plate 3b is erected at a substantially right angle to the front cushion plate 3b as shown in FIG. As for the seat body 3, above the seat cushion 1, the front cushion plate 3b is a seat cushion for infant seating, and the back cushion plate 3a is a seat back for infant seating. The back cushion plate 3a, which serves as a seat back for infant seating, and the front cushion plate 3b, which serves as a seat cushion for infant seating, are suspended and held by a belt member 7a for suspending and holding and a belt member 7b for holding a backrest, respectively. As a result, the backrest portion and the seat portion with respect to the seat back 1 are rear-facing infant seats with the seated posture maintained at a predetermined angle.

Since the infant seat thus obtained is used by the infant sitting backwards, the person sitting on the seat back 1 and the infant face each other. In addition to clearly seeing the situation, even if a collision accident occurs, the impact load exerts an extremely small burden on the neck of the infant, which provides excellent safety.In addition, the backrest for sitting the infant is configured. The belts 7a and 7b on both sides of the back side cushion plate 3a and the front side cushion plate 3b that constitutes the seating surface of the infant are prevented from shifting to both sides of the infant, and by using the seat belt 9 together, It will improve safety. Further, since a cushion member having a sufficient thickness is attached to the seating surface side of the infant seat, it is possible to exhibit an excellent sitting comfort. On the other hand, when the cushion body 3 is stored in the seat back 1, it is also sufficient. It goes without saying that a cushion member of various thickness acts so that the usability as a seat is not impaired. Further, since the back cushion plate 3a and the front cushion plate 3b are of a large shape having the same area as the concave portion 2 provided in the seat back 1, children of all body types from small children to large children can be seen. It is possible to completely comply with all of the above, and the scope of application will be greatly expanded.

[0012]
