Abstract

A child safety seat includes a seat shell, a headrest and a side protection part. The seat shell has a seat portion, a backrest portion and a sidewall, the sidewall protruding forward from the backrest portion. The headrest is connected with the backrest portion and is movable along the backrest portion, the headrest having a side support portion protruding forward. The side protection part is disposed adjacent to the sidewall at an inner side thereof, the side protection part extending along the inner side of the sidewall from a location adjacent to the seat portion toward a top of the backrest portion, a portion of the side protection part being located between the sidewall and the side support portion of the headrest.

First claim

What is claimed is:

1. A child safety seat comprising:
a seat shell having a seat portion, a backrest portion and a sidewall, the sidewall protruding forward from the backrest portion;
a headrest connected with the backrest portion and movable along the backrest portion, the headrest having a side support portion protruding forward; and
a side protection part disposed adjacent to the sidewall at an inner side thereof, the side protection part extending along the inner side of the sidewall from a location adjacent to the seat portion toward a top of the backrest portion, a portion of the side protection part being located between the sidewall and the side support portion of the headrest,
wherein the side protection part includes a first cushioning structure and a second cushioning structure that are formed integrally with the side protection part, the first cushioning structure being positioned to generally correspond to the headrest, and the second cushioning structure being located below the first cushioning structure, the first cushioning structure and the second cushioning structure being configured so that an elasticity of the side protection part differs in regions corresponding to the first cushioning structure and the second cushioning structure.

2. The child safety seat according to claim 1 , wherein the side protection part has a major surface facing the sidewall, and the first cushioning structure and the second cushioning structure are provided on the major surface.

3. The child safety seat according to claim 2 , wherein a material thickness of the first cushioning structure and the second cushioning structure is smaller than a material thickness of the side protection part in regions thereof other than the first cushioning structure and the second cushioning structure, whereby the first cushioning structure and the second cushioning structure are deformable.

4. The child safety seat according to claim 3 , wherein each of the first cushioning structure and the second cushioning structure includes a sunken region.

5. The child safety seat according to claim 1 , wherein the side support portion of the headrest and the first cushioning structure remain overlapping each other within a range of vertical adjustment of the headrest.

6. The child safety seat according to claim 1 , wherein the first cushioning structure is formed as a single sunken region having a surface area substantially overlapping with the side support portion of the headrest.

7. The child safety seat according to claim 1 , wherein the second cushioning structure includes a plurality of elongate sunken regions parallel to one another.

8. The child safety seat according to claim 1 , wherein the first cushioning structure is formed as a single sunken region, and the second cushioning structure includes a plurality of elongate sunken regions parallel to one another.

9. The child safety seat according to claim 1 , wherein the second cushioning structure occupies a surface area greater than that of the first cushioning structure.

10. The child safety seat according to claim 1 , wherein the first cushioning structure and the second cushioning structure are configured with different structural features and/or different sizes so that an elasticity of the side protection part differs in regions corresponding to the first cushioning structure and the second cushioning structure.

11. The child safety seat according to claim 1 , wherein the side protection part has two major surfaces opposite to each other, and any of the first and second cushioning structure is formed as a hollow portion of the side protection part having one or more inner cavities between the two major surfaces.

12. The child safety seat according to claim 1 , wherein the side protection part is formed as a panel.
