Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle seat that can be used as a normal adult seat at any time and can be used as a baby bed when necessary.

[0002]

[Prior art]

 As shown in Japanese Utility Model Laid-Open No. 58-170231, the seat cushion is divided in the front-rear direction, and the front part of the seat back is used as an automobile seat for carrying an infant requiring a baby bed. It has been proposed that it be raised vertically toward and forms a space between the seat back and the baby bed so that the baby bed can be placed.

However, in this automobile seat, a special mechanism for vertically holding the front half of the seat cushion that is vertically raised, a dedicated baby bed and a separate fixing device are required. Since the head and legs of a laid infant are not protected at all, there is a problem that the infant cannot be protected from a lateral impact such as a side impact.

[0004]

[Problems to be solved by the device]

 The present invention solves the above-mentioned conventional problems and does not require a special mechanism for holding the seat cushion, a separate fixing device, a dedicated baby bed, etc. It is designed to provide a car seat that can be converted and that can reliably protect infants from lateral impacts.

[0005]

[Means for Solving the Problems]

 A first invention made in order to solve the above-mentioned problem is that the top plate portion of the seat cushion is made up of left and right slide cushions, and the slide cushions on both sides are connected by a connecting shaft. The slide cushion has a structure capable of standing up with the cushion surface inside, and the front cushion can also be raised upward, and a connecting and fixing means is provided between the raised front cushion and the standing slide cushion. It is characterized by. A second invention made to solve the same problem is that the surface of the seat back is made up of left and right slide cushions, and the slide cushions on both sides are connected by a connecting shaft to slide on both sides. The structure of the cushion is such that it can be bent forward with the cushion surface inside, and the front cushion can also be raised upwards, and the connecting and fixing means is provided between the raised front cushion and the bent slide cushion. It is a feature.

[0006]

[Action]

 The automobile seat of the first invention is usually used as an adult seat, but when an infant is put on, first, the slide cushions on both sides constituting the top plate portion of the seat cushion are set with the cushion surface inside. While standing up, the front cushion is also raised upward. By connecting the raised front cushion and the raised slide cushion by connecting and fixing means, a baby bed surrounded by soft cushion surfaces on all sides can be easily formed. .

Further, in the second invention, the slide cushions on both sides forming the surface of the seat back are bent 90 ° forward with the cushion surface inside, and the front cushion is also raised upward. By connecting the raised front cushion and the bent slide cushion by the connecting and fixing means, a baby bed surrounded by cushion surfaces on all sides can be easily formed.

[0008]

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. 1 to 6 show an embodiment of the first device, and FIG. 1 shows a state in which the automobile seat of the present invention is used as an adult seat. Here, 1 is a seat cushion, 2 is a seat back, and 3 is a front cushion. As will be described later, the front cushion 3 can be raised upward.

As shown in FIGS. 2 to 4, in the first invention, the top plate portion of the seat cushion 1 is composed of slide cushions 4a and 4b divided into left and right. Further, these slide cushions 4a and 4b can be erected with the cushion surface inside as shown in FIG.

FIG. 5 is a perspective view showing a mechanism for this purpose, and a connecting shaft 5 is provided on the front surface side of each slide cushion 4a, 4b. As shown in the enlarged view of FIG. 6, the connecting shaft 5 is composed of a core material 6, a pad material 7 and a skin 8, and a conical bracket 9 protruding from both end portions of the core material 6. The slide cushions 4a and 4b are connected to each other by fitting them to the receiving bracket 10 of the slide cushions 4a and 4b. The length is set so that the slide cushions 4a and 4b on both sides in the state shown in FIG.

Further, as shown in FIG. 5, movable brackets 12a and 12b are connected to the slide cushion boards 11a and 11b on the lower surfaces of the respective slide cushions 4a and 4b through hinges, and these movable brackets 12a and 12b are connected. Is screwed to a screw shaft 13 which is left-right threaded. Therefore, when the screw shaft 13 is rotated by the motor 14 at one end of the screw shaft 13, the moving brackets 12a and 12b move left and right, and the slide cushions 4a and 4b connected by the connecting shaft 5 stand up with the cushion surface inside. Becomes Reference numeral 15 is a guide rod provided on the back side without screws, which guides the moving bracket 16 provided on the back side of the slide cushion boards 11a and 11b.

In order to convert the vehicle seat configured as described above into a baby bed, the slide cushions 4a and 4b are erected as shown in FIG. 3 by the mechanism described above, and the front cushion 3 is also drawn. Raise upward as shown in 4. By engaging the connecting and fixing means 17 provided on the side surface of the front cushion 3 with the recesses 18 at both ends of the connecting shaft 5, an infant bed having cushions on all sides and on the bottom is formed. You can

FIGS. 7 to 9 show an embodiment of the second invention, in which the surface of the seat back 2 is composed of slide cushions 19a and 19b which are divided into left and right, and between the slide cushions 19a and 19b on both sides. Are connected by a connecting shaft 20. In this device, the slide cushions 19a, 19b on both sides are bent forward with the cushion surfaces inside by the same mechanism as in the first device, and the front cushion 3 is raised upward as shown in FIG. When fixed, it can form an infant bed surrounded by cushions on all sides and bottom. Note that FIG. 9 is a view showing a connecting portion between the end portion of the connecting shaft 20 and the slide cushion 19b.

[0014]

[Effect of device]

 As explained above, the automobile seats of the first and second inventions can be used as an adult seat at any time, and when necessary, special mechanism, another fixing device, It can be immediately converted to an infant bed without the need for a dedicated infant bed. Since this baby bed is surrounded by cushions on all sides, it can reliably protect the baby from lateral impact, and because it is integrated with the car seat, it can be attached to the main body. Has the advantage that it can be done easily. Therefore, the present invention has great practical value as an automobile seat that solves the conventional problems.
