DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an automobile seat, and more particularly, to a seat that can be used as a child seat if necessary.

[Prior art to the invention]

Conventionally, there is a seat as shown in FIG. 1 as this type of seat that can also be used as a child seat.

That is, the seat 1 has a backrest/infant seat cushion 4 that fits into a recess 3 formed in the center of the seat bag 2, and a protective circle 5 that is rotatably attached to the top of the seat bag 2, and connects the two. It is composed of a belt 6. In order to use this conventional example as an infant seat, the backrest/infant seat cushion 4 and the protective circle 5 should be rotated forward, but in this state, the recess 3 is located at the part where the infant's back touches. As a result, it was difficult to adequately support the infant's back, and the seat bag had virtually no function. Further, since the protective circle 5 is configured to be housed in the upper periphery of the seat bag 2, it becomes a hindrance when the seat is used as a normal seat.

[Purpose of the invention]

Therefore, the present invention was made by focusing on such conventional problems, and its purpose is to form the side portions of the seat bag so as to be freely rotatable in the front and back direction, and to form the surrounding portion of the seat cushion. By making it rotatable in the front and back direction, it can be used as a normal seat when the side part is stored in the seat bag position and the enclosure part is stored in the seat cushion position, and the side part can be rotated forward. To provide a seat which can be used as a child seat when the two are connected to each other by turning the enclosure part to the horizontal state and by rotating the enclosure part rearward to the upright state.

[Embodiments of the invention]

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

In this embodiment, the side portions of the seat bag are formed to be freely rotatable in the front-rear direction, and the enclosing portion of the seat cushion is formed to be freely rotatable in the front-rear direction, and the side portions are rotated forward to be in a horizontal state. The gist is that the enclosure can be used as a child seat when the enclosure is rotated rearward to stand up and the two are connected via a hook mechanism or the like.

To explain this in more detail, the reference numeral 10 denotes a seat, which is composed of a seat cushion 12 and a seat back 16 attached to the rear of the seat cushion 12 via a reclining device 14 so as to be rotatable in the front and rear directions. It can be used as a regular seat. Sheet 1 like this
0 is configured so that it can be used as a child seat if necessary.

That is, the side part 17 of the seat bag 16 is formed to be rotatable in the front and back direction via the pin 18, and when the side part 17 is stored in the position of the seat bag 16, it functions as a part of the seat bag 16, and the side part 17 When rotated forward and held horizontally, the side portions 17 function as part of the infant protection section, allowing the infant's body to be restrained from the side. In addition, in the seat cushion 12,
The enclosure part 19 is formed in a gate shape with a front edge part 19A and a side edge part 19B, and is formed to be freely rotatable in the front-rear direction via a pin 20. When the enclosing part 19 is housed in the position of the seat cushion 12, it functions as a part of the seat cushion 12, and when the enclosing part 19 is rotated backward and held in an upright position, the enclosing part 19 functions as a part of the seat cushion 12. Reference numeral 19 functions as a part of the infant protection section, and is designed to restrain the infant's body from the front and rear directions. Enclosure 19
A hook mechanism is provided between the enclosing part 19 and the side part 17 so that the infant's body can be restrained from the front and back direction and from the side at the same time by holding both the upright state and the horizontal state of the side part 17. In the example,
Locking pins 21 project laterally from side edges 19B and 19B of enclosure portion 19, respectively, and corresponding hooks 22 are rotatably attached to side portion 17. The hook 22 is formed into a substantially U-shaped shape by bending a spring plate so as to be elastically engaged with the locking pin 21.

Next, how to use it will be explained.

When used as a normal seat, the side 1
7 in the position of the seat bag 16, and the enclosing part 19 in the position of the seat cushion 12, the seat 10 is in the normal use state shown in FIG.
This allows adults to be seated.

Next, when using the seat as a child seat, first rotate the enclosing portion 19 of the seat cushion 12 backward from the usage state shown in FIG. 2 and hold it in the upright state as shown in FIG. , 4th
As shown in the figure, the side portion 17 of the seat bag 16 is rotated forward and held in a horizontal state, and the hook 22 is rotated to engage the locking pin 21. As a result, both are connected and the upright state of the enclosure portion 19 and the horizontal state of the side portions 17 are locked. This makes it possible for the infant to be seated, and furthermore, the infant's body is restrained from the front, rear, and side directions, thereby preventing the automobile from suddenly stopping or starting out in the event of a collision, thereby improving safety.

In this way, the normal seat 10 can be used as a child seat if necessary, and the side portion 17 and the surrounding portion 19 can be made into a frame shape and function as a strong child protection portion. can.

5 and 6 show a second embodiment of the invention.

This embodiment has almost the same structure as the first embodiment, but only the different parts will be explained.
A, the side edge portion 19B and the center portion 19C form an E-shape, and as shown in FIG.
When the child is rotated and held in an upright position, the child's legs are brought forward from both sides of the central portion 19C, giving a good sitting posture and allowing the child to sit more safely.

FIG. 7 shows a third embodiment of the invention.

This embodiment has almost the same configuration as the previous embodiment, but to explain only the characteristic parts, when the side part 17 is rotated in the forward direction, the side part 17 moves to the outside of the side edge part 19B of the enclosure part 19. to be located in
The side portion 17 of the seat bag 16', which is larger than the seat bag 16 of the embodiment described above, is formed to be rotatable,
The hook mechanism is formed of a locking pin 21 and a hook groove 22', and the hook groove 22' is formed at a position on the front side of the side portion 17 corresponding to the locking pin 21. When the seat 10 is used as a child seat, not only can a large infant be seated therein, but the structure of the hook mechanism is also simplified. This not only makes it possible to improve operability by eliminating the trouble of operating the hook, but also increases the design effect.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various applications and modifications are possible. For example, in this embodiment, the enclosure is described as being formed in a portal shape or an F-shape, but the enclosure is not limited to this, and may be formed in an L-shape.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the side portions of the seat bag are formed so as to be freely rotatable in the front-rear direction, and the enclosing portions of the seat cushion are formed so as to be freely rotatable in the front-rear direction. The seat can also be used as a child seat by rotating the front part to the horizontal position and rotating the enclosure part backward to the upright position to connect the two, so it can be used as a regular seat. In addition to its use, it can also be used as a child seat if necessary, improving versatility. Also, when used as a child seat,
Since the enclosure and the side parts are connected in a frame-like manner, a strong child protection part is obtained, and the child's waist or chest can be restrained from the front, back and sides at the same time, making it possible to prevent sudden stops of the car or collisions. Safety can be improved at any time. Moreover, the unevenness of the seat back surface, which has been a problem in the past, can be eliminated, and the infant can be seated comfortably. Furthermore, the side space of the seat bag can be reduced, and the side space can be effectively utilized.
