[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle seat that can obtain an infant seat having a sufficient cushioning property corresponding to an infant's body shape by a simple operation only when necessary using a part of a seat back.
[0002]
[Prior art]
Conventionally, to seat an infant safely on a vehicle seat, a special child seat is usually mounted on the seat via a seat belt or the like, and the infant is normally seated on this seat, but the child seat is difficult to attach and detach. In addition, there is a problem in that a person other than the infant cannot sit after being put in the way, and there is a problem that the infant cannot be safely seated when the child seat is not prepared.
[0003]
Therefore, recently, for example, as disclosed in Japanese Patent Application Laid-Open No. 59-156836 and Japanese Utility Model Application Laid-Open No. 63-80227, for infants only by a simple operation using a part of a seat cushion, a seat back or the like. Various vehicle seats capable of obtaining a seat cushion have been proposed. However, in this type of vehicle seat, there is a problem that when the seat cushion for infants is used, the thickness of the seat back cannot be sufficiently secured and the cushioning property is inferior.
[0004]
[Problems to be solved by the invention]
The present invention solves the conventional problems as described above, and can switch from a normal seat to an infant seat cushion immediately by a simple operation when necessary, and ensures a comfortable ride even during normal use. It was completed for the purpose of providing a vehicle seat that can secure a sufficient thickness of a seat back and exhibit excellent cushioning properties even when used as an infant seat. Is.
[0005]
[Means for Solving the Problems]
The vehicle seat of the present invention made to solve the above problems is a vehicle seat in which a seat back is composed of a seat back body that can be moved forward and side seats on both sides, and the side seats on both sides described above. Is divided into two upper and lower members, a lower side seat and an upper side seat, which are installed on both sides of the lower part of the seat back body. It is converted into two modes: a normal state that constitutes drooping, and a state in which the inner side faces each other are placed on the back of the seat back body that has been tilted forward and the back is the buttocks, and both constitute a backrest for infants It is characterized by being connected so as to be freely movable.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
The drawings show a case where the present invention is applied to a rear seat for an automobile composed of a seat cushion and a seat back. In the figure, 1 is a seat cushion, 2 is a seat back, and 20 is a headrest. It is basically the same as a kind of vehicle seat.
[0007]
The seat back 2 is formed by arranging two sets of a side seat 4 on the door side and an inner side seat 5 that are not allowed to move forward on both sides of a seat back main body 3 that can be moved forward. 5 always constitutes a seat back center. And all the above-mentioned side seats 4 and 5 are the ones with the elastic support surface where the front side is an arc shape, and it is divided into two upper and lower members, and the lower side seats 4b and 5b which are the lower divided bodies are The upper side seats 4a and 5a, which are upper divided bodies, are continuously provided on the lower side seats 4b and 5b so as to be an adult together with the seat back body 3. However, when the seat back body 3 is moved forward on the back of the seat back body 3 and the inner side faces are matched with each other, It can be converted to a state in which the infant backrest is configured. That is, the upper side seats 4a and 5a are connected to the vehicle body side so as to be movable on the rear side of the seat back body 3 that is tilted forward from above the lower side seats 4b and 5b by the link mechanism.
[0008]
As the link mechanism, as shown in FIGS. 2 to 3, the upper side seats 4a and 5a are connected to the package tray and the lower portion of the rear seat by a total of two links 6 each consisting of one on the back side and one on the back side. By doing so, it is connected to the body side and can be easily rotated forward by the rotation of the link 6. Then, the upper side seats 4a and 5a moved to the rear part of the seat back body 3 which has been tilted forward are connected and fixed by insertion support by a headrest 20 in which both stays are inserted into stay fitting holes 7 provided in advance at the top. It is configured as follows. In addition, by providing the stopper 6a as necessary, the rotation of each link 6 can be restricted and the fixed state can be made more stable.
[0009]
Further, as shown in FIG. 1, the upper surface of one or both of the lower side sheets 4b and 5b is an opening 8, and the lower side sheet is configured to serve as a storage box. Convenient for storing small items. Furthermore, storage pockets 9 made of a net or the like are formed on the side surfaces of the upper side sheets 4a and 5a, and a large number of storage portions are formed together with the storage boxes.
[0010]
The seat back body 3 that is tilted forward is configured to connect and fix a leather fixing belt 10 between the support bracket 7 a attached to the stay fitting hole 7 of the headrest and the seat cushion 1. When used as an infant seat, it is configured to increase safety by regulating the vertical direction. The fixing belt 10 can also serve as an assist grip when the seat back body 3 is moved forward.
[0011]
As shown in FIG. 4, the structure configured in this way is normally provided with side seats 4 and 5 on both sides of the seat back body 3 so that the seat back 2 is integrally formed. It has the same appearance as the seat and is used as a general adult seat. In this case, the seat back 2 can obtain an excellent ride comfort with the same structure as the standard seat.
On the other hand, when carrying an infant, as shown in FIG. 1 to FIG. 3, after removing the headrest 20 from the top of the seat back body 3, the seat back body 3 is moved forward and the back surface is used as a seating surface. Next, the upper side seats 4a and 5a are rotated to the rear part of the seat back main body 3 which has been tilted forward, and are moved so that the inner side faces are in abutted shape, thereby forming a backrest for an infant on the seat back main body 3. . Further, the upper side seats 4a and 5a are connected and fixed by inserting both stays of the headrest 20 previously removed from the backrest into the stay fitting holes 7. In this way, a seating surface that is as high as the thickness of the seat back main body 3 and a backrest that is projected forward by the amount of the link 6 can be formed by a simple operation. Thus, an infant seat cushion corresponding to the above can be easily formed. In particular, since the backrest uses the upper side seats 4a and 5a, the backrest is sufficiently thick and has excellent cushioning properties. Further, in this state, the lower side sheets 4b and 5b are configured to serve as storage boxes with the upper surface of one or both of them being opened 8, and the side surfaces of the upper side sheets 4a and 5a. In addition, since the storage pocket 9 formed of a net or the like is formed, it is possible to easily store small items and the like.
[0012]
【The invention's effect】
As is clear from the above description, the present invention can immediately switch from a normal seat to an infant seat cushion by a simple operation when necessary, and can ensure a comfortable ride even during normal use. In addition, even when an infant seat is used, a sufficient thickness of the seat back can be secured and excellent cushioning properties can be exhibited.
Therefore, the present invention greatly contributes to the development of the industry as a vehicle seat that eliminates the conventional problems.
