DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat conversion structure for an infant. More specifically, the present invention relates to a structure for converting a normal seat into a child seat by partially deforming the seat.

[0002]

2. Description of the Related Art When an infant is put on a vehicle, a separately manufactured child seat is mounted on a vehicle seat and used.

[0003] However, the child seat has a problem in post-processing such as when it is not used or when it becomes unnecessary because it takes time to attach and detach.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a movable portion provided on a seat portion and a backrest portion of a vehicle seat, and can be converted into an infant seat simply by moving the movable portion. An object of the present invention is to provide a conversion structure for a child seat.

[0005]

Means for Solving the Problems In order to solve the above-mentioned problems, a vehicle seat infant conversion structure according to the present invention is characterized by adopting the following constitution. In a vehicle seat in which a seat having a seat portion and a backrest portion is fixed to a floor of a vehicle by a support, the seat portion is folded at a central portion in a width direction and separated from both side portions, so that the seat portion is folded up on a rear half. The backrest is separated from the both sides at the upper center in the width direction to fold up on the lower backrest to form a pillow for an infant. It has a deployment part, and a drawer part is provided at the middle of both sides in the vertical direction, by separating it from the upper and lower parts, pulling it forward, and forming side guards for infants on both sides of the seat for infants. are doing.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a vehicle seat conversion structure according to the present invention;

[0007] In each of the figures, reference numeral A denotes a vehicle seat. The vehicle seat A includes a support 1, a seat 2, and a backrest 3.

A support 1 is fixed to the floor of a vehicle, a seat 2 is mounted on the upper side as shown in FIGS. 1 and 2, a backrest 3 is mounted on the rear side, and a backrest 3 is mounted on the upper side of the backrest 3. The headrest 4 is attached.

The seat 2 is formed by separating almost half of the front part of the center part in the width direction from the two parts 2a on both sides, so that when the seat part 2 is deployed to the rear side, it rises to the rear half of the seat part 2 in FIG. As shown in FIG. 2, it is folded to form a deployed portion 2b for constituting a seat for an infant. Therefore, the deploying portion 2b has a configuration suitable for sitting on the back side as well as the front side.

The unfolded portion 2b is provided with a seat 2 fixed to the upper portion of the rear end serving as the unfolded center by a sheet-like hinge 5 made of a sheet such as a leather or a synthetic resin sheet that is flexible and resistant to repeated bending and stretching. A locking mechanism (not shown) is provided for connecting and deploying and closing the deploying portion 2b while being supported by the fixed seat portion 2 and for locking in the deployed and closed condition. Let it do.

When the unfolded portion 2b is unfolded to form a seat for an infant, a leg support 6 for receiving the leg of the infant is required. For this reason, when the horizontal guide 7 is provided inside the developing portion 2b and the leg support 6 is movably engaged with the guide 7 and the developing portion 2b is deployed, the leg support 6 is moved to the position shown in FIG. 3 and 4, the child is pulled out to support the infant's leg.

The backrest 3 is separated from the rice pad on the upper side of the central part in the width direction, so that when the backrest is developed downward, the backrest 3 is placed on the backrest 3 located in this part as shown in FIGS. It is folded up to form an unfolded portion 3a for forming a pillow for an infant, and the unfolded portion 3a is also configured such that the back side thereof is also suitable for a pillow. Install and place.

The unfolded portion 3a is a sheet-like hinge 10 having a lower end serving as a unfolded center formed of a material having characteristics suitable for a hinge such as leather or a synthetic resin sheet.
In such a manner that the deploying portion 3a is deployed and closed, and a lock mechanism (not shown) for stopping the deploying portion 3a in the deployed and closed state is provided.

The upper and lower portions of both sides of the back portion 3 are separated from the upper and lower portions 3b and 3c, so that when the seat portion is pulled out forward, the infant seat is constituted by the developing portion 2b of the seat portion 2. The drawers 3d constitute side guards for infants on both sides of the drawer.

The drawer 3d is provided with a moving guide 11 which is oriented vertically in the front and rear directions, and is engaged with a sliding body 12 which is mounted on the upper and lower parts 3b and 3c. The moving guide 11 is provided with a plurality of locking grooves 13 on both sides thereof, and the sliding body 12 has a structure in which claws 14 which are engaged with the locking grooves 13 are protrudingly provided. The sliding body 12 is made of an elastic material such as rubber,
Formed into a structure with a hollow part 15 to make it more elastic,
When the drawer 3d is pulled out, the engagement between the locking groove 13 and the claw 14 allows the drawer 3d to be reliably stopped at a plurality of desired positions.

[0016]

According to the present invention, the seat is suitable for an infant by folding the central movable part of the seat back to the rear side, folding the central movable part of the backrest downward, and sliding both sides of the backrest forward. It can be used immediately by converting it to a child seat with a seat, backrest and side guards.After use, return each movable part to its original state to save the storage and storage. It is very convenient because it does not require it.
