Abstract

A child high chair includes a high chair frame, a booster seat and a youth seat assembled with each other. A booster seat backrest is rotatably disposed on a booster seat bottom. A booster seat headrest is rotatably disposed on the booster seat backrest and opposite to the booster seat bottom. A booster seat reclining mechanism is located inside the booster seat backrest and actuated to rotate the booster seat headrest while the booster seat backrest is rotated relative to the booster seat bottom. A youth seat footrest is rotatably disposed on a youth seat bottom. A youth seat backrest is rotatably disposed on the youth seat bottom and opposite to the youth seat footrest. A youth seat reclining mechanism is located inside the youth seat bottom to rotate the youth seat footrest via rotation of the youth seat backrest simultaneously driven by reclining of the booster seat backrest.

First claim

What is claimed is:

1. A child high chair, comprising:
a high chair frame;
a youth seat disposed on the high chair frame, the youth seat comprising:
a youth seat bottom;
a youth seat footrest rotatably disposed on the youth seat bottom;
a youth seat backrest rotatably disposed on the youth seat bottom and opposite to the youth seat footrest; and
a youth seat reclining mechanism located inside the youth seat bottom and connected between the youth seat footrest and the youth seat backrest; and

a booster seat movably disposed on the youth seat bottom, the youth seat footrest being rotated relative to the youth seat bottom via the youth seat reclining mechanism while the youth seat backrest is simultaneously rotated by reclining of the booster seat;
wherein the booster seat backrest comprises a rib contacting against the youth seat backrest, and the youth seat backrest is rotated by pressure of the rib while the booster seat backrest is rotated relative to the booster seat bottom.

2. The child high chair of claim 1 , wherein the booster seat comprises:
a booster seat bottom;
a booster seat backrest rotatably disposed on the booster seat bottom;
a booster seat headrest rotatably disposed on the booster seat backrest and opposite to the booster seat bottom; and
a booster seat reclining mechanism located inside the booster seat backrest and connected between the booster seat bottom and the booster seat headrest, the booster seat reclining mechanism being actuated to rotate the booster seat headrest relative to the booster seat backrest while the booster seat backrest is rotated relative to the booster seat bottom.

3. The child high chair of claim 1 , wherein the youth seat reclining mechanism comprises a backrest linking component, a bottom rocker and a footrest linking component, the backrest linking component is rigidly connected to the youth seat backrest, the footrest linking component is rotatably connected to the youth seat footrest, the bottom rocker is pivotally connected inside the youth seat bottom, and two arms of the bottom rocker are respectively connected to the backrest linking component and the footrest linking component.

4. The child high chair of claim 3 , wherein the backrest linking component is rigidly connected to the youth seat backrest via a square tube, and synchronously rotated in accordance with rotation of the youth seat backrest relative to the youth seat bottom.

5. The child high chair of claim 3 , wherein the two opposite arms of the bottom rocker comprises a first rocker arm and a second rocker arm, the first rocker arm is slidably located inside a backrest slot structure formed on the backrest linking component, and the footrest linking component is slidably located inside a rocker slot structure formed on the second rocker arm.

6. The child high chair of claim 5 , wherein the youth seat footrest is rotated by pulling of the footrest linking component while the first rocker arm contacts against an end of the backrest slot structure and the footrest linking component contacts against an end of the rocker slot structure.

7. The child high chair of claim 1 , wherein the booster seat headrest is rotated inwardly relative to the booster seat backrest and the youth seat footrest is rotated upwardly relative to the youth seat bottom in accordance with reclining of the booster seat upon the youth seat.

8. The child high chair of claim 1 , wherein the booster seat reclining mechanism comprises a curved linking component passing through the booster seat backrest, a first link end of the curved linking component is pivotally connected to the booster seat headrest, and a second link end of the curved linking component opposite to the first link end is pivotally connected to the booster seat bottom.

9. The child high chair of claim 8 , wherein a pivot between the first link end and the booster seat headrest is distant from a pivot between the booster seat headrest and the booster seat backrest, and a pivot between the second link end and the booster seat bottom is distant from a pivot between the booster seat backrest and the booster seat bottom.

10. The child high chair of claim 8 , wherein the booster seat reclining mechanism further comprises a headrest slot structure disposed on the booster seat headrest, and the first link end of the curved linking component is slidably located inside the headrest slot structure.

11. The child high chair of claim 10 , wherein the booster seat headrest is not rotated relative to the booster seat backrest while the first link end is slid inside the headrest slot structure, and the curved linking component is actuated to rotate the booster seat headrest relative to the booster seat backrest while the first link end contacts against an end of the headrest slot structure.

12. The child high chair of claim 1 , wherein the booster seat reclining mechanism comprises a backrest rocker, a headrest linking component, a bottom linking component, a backrest cam and a seat follower, the backrest rocker is pivotally connected inside the booster seat bottom, two opposite ends of the headrest linking component are respectively connected to a first rocker arm of the backrest rocker and the booster seat headrest, two opposite ends of the bottom linking component are respectively connected to a second rocker arm of the backrest rocker and the seat follower, the backrest cam is fixed to the booster seat backrest, the seat follower is movably disposed on the booster seat bottom and slidably contacts against the backrest cam.

13. The child high chair of claim 12 , wherein the backrest cam moves the seat follower into a retracted position while the booster seat backrest is reclined, and the seat follower pulls rotation of the backrest rocker via the bottom linking component to rotate the booster seat headrest.

14. The child high chair of claim 12 , wherein the booster seat reclining mechanism further comprises a resilient component disposed between the seat follower and the booster seat bottom, the backrest cam is separated from the seat follower and the seat follower is recovered to an extended position via the resilient component while the booster seat backrest is upright, and the backrest rocker is rotated by movements of the seat follower and the bottom linking component, to recline the booster seat headrest via the headrest linking component.

15. The child high chair of claim 12 , wherein a pivot between the headrest linking component and the booster seat headrest is distant from a pivot between the booster seat headrest and the booster seat backrest.

16. The child high chair of claim 1 , wherein the booster seat reclining mechanism comprises a backrest rocker, a headrest linking component and a seat linking component, the backrest rocker is pivotally connected inside the booster seat backrest, two opposite ends of the headrest linking component are respectively connected to a first rocker arm of the backrest rocker and the booster seat headrest, and two opposite ends of the seat linking component are respectively connected to a second rocker arm of the backrest rocker and the booster seat bottom.

17. The child high chair of claim 16 , wherein while the booster seat backrest is reclined or upright, the backrest rocker is rotated to drive the headrest linking component to push or pull the booster seat headrest accordingly, so as to rotate the booster seat headrest accordingly.
