Abstract

An infant support seat includes an upper structure, a lower frame structure, and a seat structure. The lower frame structure is connected to the upper frame structure to define a containing space with the upper frame structure and be located under the containing space. The seat structure is disposed in the containing space. The seat structure includes a seat back and a seat bottom. The seat back is rotatable relative to the lower frame structure for rotating between a lying position and a sitting position. The seat bottom is pivotally joined to the seat back. The seat bottom is rotatable relative to the lower frame structure to form a lying surface cooperatively with the seat back when the seat back rotates to the lying position and rotate to be tilted upward relative to the lower frame structure when the seat back rotates to the sitting position.

First claim

What is claimed is:

1. An infant support seat comprising:
an upper frame structure;
a lower frame structure connected to the upper frame structure to define a containing space with the upper frame structure and be located under the containing space; and
a seat structure disposed in the containing space, the lower frame structure having two upright mounts, the two upright mounts extending from two ends of the lower frame structure respectively for mounting on a support frame to make the seat structure suspended on the support frame, the seat structure comprising:
a seat back rotatable relative to the lower frame structure for rotating between a lying position and a sitting position; and
a seat bottom pivotally joined to the seat back, the seat bottom being rotatable relative to the lower frame structure to form a lying surface cooperatively with the seat back when the seat back rotates to the lying position and rotate to be tilted upward relative to the lower frame structure when the seat back rotates to the sitting position.

2. The infant support seat of claim 1 , wherein the upper frame structure is connected to the two upright mounts respectively to be located above the lower frame structure for defining the containing space cooperatively with the lower frame structure and the two upright mounts.

3. The infant support seat of claim 1 , wherein at least one side of the lower frame structure has an upright plate extending therefrom, a guide detail is formed on the upright plate, the seat back has a guide pin slidably disposed through the guide detail, the seat bottom is pivotally connected to the upright plate, a pivotal position of the seat back and the seat bottom is located between the guide pin and a pivotal position of the seat bottom and the upright plate, and during rotation of the seat back, the guide pin slides along the guide detail to guide the seat back to rotate between the lying position and the sitting position and the seat bottom rotates together with the seat back via pivotal connection between the seat back and the seat bottom.

4. The infant support seat of claim 3 , wherein the seat back further has a positioning pin, and the upright plate further has a first positioning groove and a second positioning groove corresponding to the positioning pin; when the seat back rotates to the lying position, the positioning pin is engaged with the first positioning groove to fix the seat back at the lying position; when the seat back rotates to the sitting position, the positioning pin is engaged with the second positioning groove to fix the seat back at the sitting position.

5. The infant support seat of claim 4 , wherein a third positioning groove is formed between the first positioning groove and the second positioning groove; when the positioning pin is engaged with the third positioning groove, the seat back is fixed at a recline position located between the lying position and the sitting position.

6. The infant support seat of claim 5 , wherein when the seat back rotates from the recline position to the sitting position, sliding of the guide pin along the guide detail and pivotal connection of the seat back and the seat bottom constrain the seat bottom at a same tilted angle.

7. An infant support seat comprising:
an upper frame structure;
a lower frame structure connected to the upper frame structure to define a containing space with the upper frame structure and be located under the containing space; and
a seat structure disposed in the containing space, the seat structure comprising:
a seat back pivoted to the lower frame structure for rotating between a lying position and a sitting position;
a seat bottom having a bridge portion and a bottom portion, the bridge portion being pivoted to the bottom portion and the seat back respectively, the bottom portion being pivoted to the lower frame structure; and
two side panels located at two sides of the bridge portion respectively, a first side of each side panel being slidably pivoted to the bridge portion, a second side of each side panel being slidably connected to the seat back and the bottom portion, the first side being opposite to the second side;
wherein when the seat back rotates from the lying position to the sitting position, the first side of each side panel slides along the bridge portion and the second side of each side panel slides on the seat back and the bottom portion respectively with rotation of the seat back to make each side panel pivots upwardly and inwardly relative to the bridge portion, so as to guide the bottom portion to rotate together with the seat back to be tilted upward relative to the lower frame structure.

8. The infant support seat of claim 7 , wherein the bridge portion has a first guide shaft, a second guide shaft, and two sliding bases slidable along the first guide shaft and the second guide shaft, the two sliding bases are pivoted to the first sides of the two side panels respectively;
wherein when the seat back rotates from the lying position to the sitting position, the first side of each side panel slides outwardly along the first guide shaft and the second guide shaft of the bridge portion via the corresponding sliding base.

9. The infant support seat of claim 7 , wherein the seat back has two first guide tracks formed on two sides of the seat back, the bottom portion has two second guide tracks formed corresponding to the first guide tracks, a guide pin being formed along the second side of the side panel and having a first end portion slidably disposed in the corresponding first guide track and a second end portion slidably disposed in the corresponding second guide track;
wherein when the seat back rotates from the lying position to the sitting position, the first end portion of the guide pin of each side panel slides along the corresponding first guide track and the second end portion of the guide pin of each side panel slides along the corresponding second guide track to make each side panel pivots upwardly and inwardly relative to the bridge portion.

10. The infant support seat of claim 7 , wherein each side panel is in a trapezoid shape having a top line corresponding to the first side and a base line corresponding to the second side.
