2. Description of the Related Art Conventionally, in order to safely seat an infant on a vehicle seat, it is common to mount a special child seat on the seat via a seat belt or the like and seat the infant on it. There is a problem in that it is troublesome to put on and take off the operation and people other than the infant cannot sit after the attachment, which is an obstacle, and it is not possible to safely seat the infant when the child seat is not prepared. was there.

Therefore, recently, for example, JP-A-59-15 is used.
As disclosed in Japanese Patent No. 6836 and Japanese Utility Model Laid-Open No. 63-80227, a vehicle seat in which an infant seat cushion can be obtained only when necessary by a simple operation using a part of a seat cushion or a seat back. Have been proposed. However, in this type of vehicle seat, there is a problem in that the riding comfort is impaired because the seat surface state during normal use is a structure in which two cushion bodies are stacked.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and can immediately switch from a normal seat to an infant seat cushion by a simple operation when necessary and normally use it. The purpose of the present invention is to provide a vehicle seat that can ensure a comfortable ride even at times, and can be used as an armrest as needed, and has a simple structure and can be produced at low cost. It has been completed.

[0005]

The vehicle seat of the present invention, which has been made to solve the above-mentioned problems, is provided with a pair of recesses for fitting armrests on the surface of a seat back with a backrest portion interposed therebetween. The lower cushion body has a base portion pivotally attached to the lower portion thereof and can be pulled forward. There are two modes: a state of being overlapped with the lower cushion body and a state of being extended inward from the lower cushion body. It is characterized by accommodating an armrest formed of a convertible upper cushion body.

[0006]

The vehicle seat thus configured usually has an armrest housed in a recess for fitting an armrest of a seat back, and has an appearance similar to that of a normal vehicle seat. One of the armrests is pulled out for use and is used as a general adult seat.However, when an infant is put on, both armrests are pulled down from the seat back, and the upper cushion body of each armrest is placed inside 180 to the seat side
If the two side portions are brought into close contact with each other after being folded once, it is possible to easily form an infant seat cushion having a seat height suitable for an infant on the seating portion.

A lower cushion body 5a in which a base portion is pivotally attached to a lower portion of each recess 4 and can be pulled forward, a state in which the lower cushion body 5a is overlapped and a state in which the lower cushion body 5a extends inward. Upper cushion body 5b convertible into two modes
The upper cushion body 5b is placed on the lower cushion body 5a when it is housed in the recess 4 and when it is used as an armrest. Since the inner side, that is, one side portion on the seating portion 1a side is connected by a skin material like a hinge, the upper cushion body 5b is moved to the seating portion side 1
A seat cushion for infants for adjusting the seat height can be formed on the seat portion 1a by folding both sides so that both side portions closely face each other.

Reference numeral 7 is a seat belt used when an adult is seated, and 8 is a child seat belt 8 housed in the recess 4 for fitting the armrest. On the other hand, a center buckle body 9 for connecting the infant seat belt 8 is housed in the seating portion 1a, and this center buckle body 9 has a pad body 9 on the back side as shown in FIG.
a is affixed, and when not in use, the pad body 9a is housed at a predetermined position of the seating portion 1a with the front surface side of the seat body 1a, and the cushioning property of the seat can be secured.

Reference numeral 9b is a crotch belt which can be pulled out when the center buckle body 9 is used, and 5c is the center buckle body 9 which is an upper portion of the infant seat cushion when the infant seat belt 8 is used as described later. It is a slit to pull out. Further, as shown in FIG. 5, the infant seat belt 8 is equipped with a height adjusting mechanism 10 so that the pulling-out position can be adjusted according to the body shape of the infant to be seated, and the vertical slit 11 is formed. The height can be adjusted freely within the range.

The structure as described above is usually shown in FIG.
As shown in FIG. 3, the armrest 5 is housed in the recess 4 for fitting the armrest of the seat back 2 and has an appearance similar to that of a normal vehicle seat. The seat portion 1a has a structure similar to that of the standard seat, and can provide an excellent riding comfort, although it is used as a seat for a general adult. On the other hand, when an infant is put on, as shown in FIG. 6, the two armrests 5 and 5 are pulled down from inside the recesses 4 and 4 at the position where the backrest portion 3 of the seatback 2 is sandwiched, and further each armrest 180 of the upper cushion bodies 5b of No. 5 to the seating portion 1a side respectively.
If you fold it once and make both sides closely contact each other, the seat 1
The infant seat cushion for adjusting the seat height can be easily formed on a. Then, by pulling out and connecting the infant seat belt 8 housed in each armrest fitting recess 4 and the center buckle body 9 housed in the seating portion 1a, the infant can be firmly and safely fixed. . In this case, the center buckle body 9 can be easily pulled out upward through the slit 5c of the cushion body 5a.

If the physical size of the infant is slightly larger than that of the infant, the seat cushion 1 without folding the upper cushion body 5b of the armrest 5 as shown in FIG.
The seating surface 1a may be used and the seat belt 8 for an infant may be used for fixing.

In addition to being able to obtain a seat cushion for infants having a surface height, it is possible to ensure a comfortable riding comfort even during normal use, and because the structure is simple, it can be produced at low cost. Therefore, the present invention is a vehicle seat that eliminates the conventional problems,
The areas that contribute to the development of industry are extremely large.
