Abstract

A child safety seat includes a seat shell and a buffering part. The seat shell includes a backrest portion and two sidewalls, the backrest portion having a front surface facing forward that is suitable to provide support for a child's back, the two sidewalls being respectively disposed at a left and a right side of the seat shell for restricting sideways movements of a child who sits in the seat shell, one of the two sidewalls having a sidewall portion located in front of the front surface. The buffering part is connected with the seat shell, the buffering part being operable to protrude sideways at an outer side of the sidewall portion.

First claim

What is claimed is:

1 . A child safety seat comprising:
a seat shell including a backrest portion and two sidewalls, the backrest portion having a front surface facing forward that is suitable to provide support for a child's back, and the two sidewalls being respectively disposed at a left and a right side of the seat shell for restricting sideways movements of a child who sits in the seat shell, one of the two sidewalls having a sidewall portion located in front of the front surface; and a buffering part connected with the seat shell, the buffering part being operable to protrude sideways at an outer side of the sidewall portion.

2 . The child safety seat according to claim 1 , wherein a smallest distance between the front surface and an image of the buffering part projected on a vertical plane perpendicularly intersecting the front surface is between about 1 mm and about 200 mm, the vertical plane being equidistant to the two sidewalls.

3 . The child safety seat according to claim 1 , wherein a smallest distance between the front surface and an image of the buffering part projected on a vertical plane perpendicularly intersecting the front surface is between about 5 mm and about 170 mm, the vertical plane being equidistant to the two sidewalls.

4 . The child safety seat according to claim 1 , wherein a smallest distance between the front surface and an image of the buffering part projected on a vertical plane perpendicularly intersecting the front surface is between about 10 mm and about 140 mm, the vertical plane being equidistant to the two sidewalls.

5 . The child safety seat according to claim 1 , wherein a smallest distance between the front surface and an image of the buffering part projected on a vertical plane perpendicularly intersecting the front surface is between about 15 mm and about 100 mm, the vertical plane being equidistant to the two sidewalls.

6 . The child safety seat according to claim 1 , wherein the buffering part is movably connected with the sidewall portion for movement between a first and a second position, the buffering part being retracted toward the sidewall portion in the first position and protruding sideways at an outer side of the sidewall portion in the second position.

7 . The child safety seat according to claim 6 , wherein the buffering part is pivotally connected with the sidewall portion.

8 . The child safety seat according to claim 1 , wherein the buffering part is disposed adjacent to a shoulder height of a child sitting in the seat shell.

9 . The child safety seat according to claim 1 , wherein the buffering part is disposed on the sidewall portion at a height from a seat plane that is between about 280 mm and about 370 mm, the seat plane generally corresponding to a support surface of the child safety seat on which a child sits.

10 . The child safety seat according to claim 1 , wherein the buffering part is disposed on the sidewall portion in a region that extends forward within about 75 mm from the front surface of the backrest portion.
