Abstract

The present invention relates to a portable car seat comprising: a seat part on which a child sits; a backrest part rotatably coupled to the seat part; a rotation connection part for rotating the seat part and the backrest part; and a rotation prevention part for restricting rotation, performed by the rotation connection part, through a stopper for preventing rotation.

Claims

1. A portable car seat comprises:

a seat part configured to have a child sit thereon, and which is configured to be mounted on a car seat;

a backrest part connected to the seat part and configured to face a back of the child sitting on the seat part;

a rotation part configured to rotatably connect the seat part to the backrest part; and

a harness belt configured to hold the child sitting on the portable car seat to the backrest part and the seat part,

wherein the seat part rotates about the backrest part and switches between a portable state in which the seat part is disposed to face a rear surface of the backrest part and a seating state in which the seat part is inclined toward a front surface of the backrest part and disposed to be in a chair form,

wherein the backrest part includes;

a backrest frame; and

a reinforced frame formed in a width direction on the backrest frame, and

wherein seat belt fixing buckles are coupled to both sides, in a width direction, of a front side of the backrest frame to fix a seat belt provided on a vehicle so that the backrest part is mounted on the car seat.

2. The portable car seat of claim 1, wherein the backrest frame includes:

a rotation origin formed at a back side of a lower end thereof to allow the seat part to rotate,

a rotation preventing point formed at the front side of the lower end thereof and being in contact with the car seat to prevent the backrest part from rotating toward a space in which the child sits, and

wherein the rotation preventing point is positioned ahead of the rotation origin.

3. The portable car seat of claim 2, further comprising a backrest-cushion part connected to the front surface of the backrest part.

4. The portable car seat of claim 2, wherein the seat part includes:

a seat frame; and

a cover covering the seat frame.

5. The portable car seat of claim 2, wherein the rotation part includes:

a rotation connection part rotating the seat part with respect to the backrest part; and

a rotation prevention part restricting rotation of the seat part with respect to the backrest part.

6. The portable car seat of claim 5, wherein the rotation connection part includes:

a rotation frame provided in the width direction at the lower end of the backrest frame and serving as a rotating shaft allowing the seat part to rotate; and

a rotation coupling unit rotatably provided on the rotation frame and connected to an end of the seat part.

7. The portable car seat of claim 5, wherein the rotation prevention part includes:

a stopper provided in the width direction at the lower end of the backrest frame; and

a stopper facing part provided in the width direction at a position facing the stopper when the seat part rotates, and preventing rotation of the seat part toward a space in which the child sits.

8. The portable car seat of claim 1, wherein the harness belt includes a shoulder cushion part and a fixing buckle and allows the child to be indirectly fixed to the vehicle.

9. The portable car seat of claim 1, further comprising a headrest part positioned at an upper side of the backrest part to support a head of the child.

10. The portable car seat of claim 9, wherein the headrest part includes:

a headrest frame; and

a cover covering the headrest frame.

11. The portable car seat of claim 9, wherein the headrest part is provided to support back, left and right sides of the head of the child sitting on the seat part.
