Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a child seat for a vehicle in which a normal rear seat can be converted to a baby seat.

[Conventional technology]

It is well known that a child seat is separately prepared and placed on a seat cushion portion.

[Problems to be solved by the invention]

However, such a child seat becomes obstructive when not in use, and a storage space is also troubled.

In view of the above, an object of the present invention is to provide a child seat of a vehicle that can convert a part of a seat back of a rear seat and a part of a package tray to an infant when necessary.

[Means for solving the problem]

In order to achieve this object, according to the present invention, the rear seat is hinged at the base end so that the seat back can be overlapped with the cushion portion, and the rear surface of the seat back is formed as a baby cushion portion. Further, a seat back portion that partially forms an infant seat back subsequent to the infant cushion portion is formed by projecting from the base end to the rear, and the back surface of the package tray portion located behind the rear seat is provided for the infant seat. The front end of the package tray portion is hinged so as to be formed as the remaining portion of the back and to be connected to the seat back portion at the overlapping position by rotating from the normal position. Guide the slide bar that is manually slid to lock in the normal position and the overlapping position. At the same time, a striker is provided which automatically engages in a recess formed at the end of the slide bar in a body portion at a position corresponding to the normal position and the overlapping position in a spring-biased state, and which is disengaged by operating the slide bar. The package tray portion guides a lock bar that is manually slid to support the package tray portion at the normal package tray position and the seat back position,
An end of the lock bar is automatically engaged with the rear portion of the body and the front end of the seat back portion in a spring-biased state, and an anchor is provided which is disengaged by operating the lock bar.

According to the second aspect, the rear surface of the seat back, the left and right sides of the seat back portion and the package tray portion are formed so as to protrude as side support portions so that the conversion operation can be easily performed with a simple structure for infants. It is conceivable that the front end portion of the package tray portion is formed as a headrest portion.

[Action]

When converting the rear seat and package tray to an infant seat, the slide back is unlocked and rotated to lock the seat back on the cushion so that the seat back overlaps with the cushion, so that the back of the seat back is used for the infant. The seat back portion used as the cushion portion and protruding from the base end portion that is interlocked thereto is defined as a lower portion of the infant seat back. By rotating the package tray portion behind from the normal position by unlocking the lock bar, the package tray portion is connected to the seatback portion upward and locked at the seatback position, thereby completing the infant seatback.

〔Example〕

1 to 4 show a child seat of a vehicle according to an embodiment of the present invention.

In FIG. 1, one of the seat backs 2 of the rear seats 1 on both sides is mounted on its cushion portion 3 by rotatably supporting a base end portion thereof on a shaft 5 attached to a body. ing. The rear surface of the seat back 2 is formed as a soft infant cushion portion corresponding to the body shape of a child up to about four years old, and the left and right sides thereof are formed so as to protrude as side support portions 21 (see FIG. 4). ). In addition, the base end of this back,
An infant seat back portion 22 is formed so as to protrude in the direction substantially orthogonal to the back so as to form a part of the infant seat back.

In order to lock the seat back 2 at the normal position and the overlapping position, as shown in FIG. 2, a slide bar is provided below a button 26 protruding from the upper end of the seat back 2 and guided by a guide 27a. There is provided a lock member comprising a lock block 27 formed integrally with the rod and urged upward from below by a spring 29 and having a curved outer peripheral surface 28a and a concave portion 28b. Then, the strikers 25, 25a fixed to the body at positions corresponding to the normal position and the overlapping position
However, it slides on the outer peripheral surface 28a and engages with the concave portion 28b. By pressing the button 26, the striker 25 is disengaged from the concave portion 28b, the seat back 2 is tilted forward so as to be placed around the outer peripheral surface 28a, and further rotated to the overlapping position, the striker 25a moves along the outer peripheral surface 28a. The recess 28b is engaged.
The same unlocking and locking operations are performed when the device is positioned at the normal position.

Package tray 4 located behind seat back 2
The package tray portion 30, which is a part of the child seat, is rotatably supported at its front end by a body shaft 31 so as to form the remaining portion of the infant seat back, and has a rear surface formed of a high height as an infant seat back. 32 with softness and softness adapted to protect the head at the top
Also, a side support portion 33 is formed by raising both sides (see FIG. 4). Correspondingly, both sides of the seat back portion 22 are similarly formed as side support portions 23.

A spring 35 is provided on the package tray portion 30 to support the package tray at the normal package tray position and the seat back position.
A lock rod 36 which is urged rearward and is engaged and supported by an anchor 37 fixed at a normal position, and a knob 38 which slides the lock rod forward on the package tray surface to disengage the lock rod 36. Are provided. Then, as shown in FIG. 3, when the package tray portion 30 is rotated from below to the package tray position, it slides along the curved surface 36a of the tip of the lock rod 36 guided by the guide 39, and once retreats. Support plate 37a formed in the gap between the anchors 37
Locked to. The lower surface of the support plate is formed in a curved surface, and the upper surface is formed flat, so that the lock rod 36 can be automatically locked by sliding in and can be securely locked by being restrained by the flat surface. An anchor 37 having a similar shape is also provided at the front end of the seat back portion 22.When the package tray portion 30 is rotated downward when using a child seat, the anchor 37 is connected to the seat back portion 22 at a position connected thereto. The other side of the lock bar 36 and the curved surface 36a slides in and is locked. The seat back portion 22 includes a crotch belt portion 40 of an infant seat belt, and a package tray portion.
30 has shoulder belt portions 41 on both sides attached thereto. At the rear end of the package tray portion 30, a flap 42 that is gripped during the rotation operation is attached.

The operation of the child seat of the vehicle configured as described above is as follows.

In FIG. 1, as shown by a solid line, the seat back 2 functions as an adult 9 in a normal state, and the surface of the package tray portion 30 performs its original function in a horizontal state. When the seat back 2 is used as a child seat, the seat back 2 is pushed forward by pushing the button 26, and the seat back 2 is overlaid on the cushion portion 3 and locked at that position. Further, the user pulls the knob 38 forward to rotate the package tray portion 30 to lock the package tray portion 30 at the connecting position with respect to the seat back portion 22. As a result, as shown in the dotted line in FIG. 1 and in FIG. 4, a child seat back lower than that for an adult is formed, and the child seat back can be seated in the concave portion 2a inside the side support portion 21, and the seat belt can be further worn.

〔The invention's effect〕

According to the first aspect of the present invention, the rear seat back and the package tray normally used for adults can be converted to babies or infants by a simple operation of the biased slide operation portion. Therefore, it is not necessary to separately bring the child seat into the vehicle interior. In addition, a sufficient height can be secured by diverting the package tray to a part of the child seat back.

According to the second aspect of the present invention, the rear side of the seat back, the left and right sides of the seat back portion and the package tray portion are formed as side support portions, and the front end portion of the package tray portion is formed as a headrest portion. Is easily configured, and the conversion operation is also simplified.
