Abstract

A child safety seat includes a seat shell for receiving a child and having a backrest and a front end opposite to the backrest, an extension member connected with the seat shell, and a latching mechanism. The extension member is positionable in a first configuration where the extension member rises upward at the front end of the seat shell, and in a second configuration where the extension member stretches forward and downward from the front end of the seat shell. The latching mechanism is operable to lock the extension member with respect to the seat shell in any of the first and second configurations.

First claim

What is claimed is:

1. A child safety seat comprising:
a seat shell for receiving a child, the seat shell having a backrest and a front end opposite to the backrest;
an extension member connected with the seat shell, the extension member being positionable in a first configuration where the extension member rises upward at the front end of the seat shell, and in a second configuration where the extension member stretches forward and downward from the front end of the seat shell, wherein the extension member includes a first adjustable part slidably connected with the seat shell, and a second adjustable part pivotally connected with the first adjustable part about a pivot joint, the first adjustable part being slidable relative to the seat shell to increase or reduce a distance between the pivot joint and the front end of the seat shell, the second adjustable part rising upward from the pivot joint in the first configuration and stretching forward and downward from the pivot joint in the second configuration; and
a latching mechanism operable to lock the extension member with respect to the seat shell in any of the first and second configurations.

2. The child safety seat according to claim 1 , wherein the first adjustable part includes a support bar, and the second adjustable part includes a panel.

3. The child safety seat according to claim 1 , wherein the latching mechanism includes a first and a second latch, the first latch being operable to lock the first adjustable part in position so as to prevent sliding of the first adjustable part relative to the seat shell, and the second latch being operable to rotationally lock the second adjustable part with respect to the first adjustable part.

4. The child safety seat according to claim 3 , wherein the first latch is assembled with the first adjustable part and is movable to engage and disengage the seat shell, the first adjustable part being locked in position when the first latch engages the seat shell, and the first adjustable part being unlocked for sliding adjustment relative to the seat shell when the first latch is disengaged from the seat shell.

5. The child safety seat according to claim 4 , wherein the seat shell includes a plurality of locking openings, and the first latch engages with any of the locking openings to lock the first adjustable part with the seat shell.

6. The child safety seat according to claim 4 , wherein the latching mechanism further includes a first spring operable to urge the first latch for engagement with the seat shell.

7. The child safety seat according to claim 3 , wherein the pivot joint includes a first coupling portion fixedly connected with the first adjustable part and a second coupling portion fixedly connected with the second adjustable part, the first and second coupling portions being pivotally connected with each other about a pivot axis, and the second latch being movable along the pivot axis between a locking and an unlocking position, the second latch being engaged with the first and second coupling portions in the locking position to prevent rotation of the second adjustable part, and the second latch being disengaged from one of the first and second coupling portions in the unlocking position for rotation of the second adjustable part.

8. The child safety seat according to claim 7 , wherein the latching mechanism further includes a second spring connected with the second latch, the second spring being operable to bias the second latch toward the locking position.

9. The child safety seat according to claim 7 , wherein the latching mechanism further includes a release actuator connected with the second latch, the release actuator being operable to urge the second latch to move from the locking position to the unlocking position for unlocking the second adjustable part.

10. The child safety seat according to claim 9 , wherein the latching mechanism further includes a linking assembly operable to movably link the first latch and the second latch so that an operation of the release actuator causes the first and second latches to move concurrently for unlocking the first and second adjustable parts.

11. The child safety seat according to claim 10 , wherein the linking assembly includes a first actuating part movably assembled with the first adjustable part and in sliding contact with the first latch, a second actuating part disposed adjacent to the second latch and movably assembled between the first and second coupling portions, and a wire respectively connected with the first and second actuating parts, an operation of the release actuator for unlocking the second adjustable part causing the second latch to urge the second actuating part to move so that the second actuating part pulls the first actuating part in movement for urging the first latch to unlock the first adjustable part.

12. The child safety seat according to claim 11 , wherein the first actuating part is slidably assembled with the first adjustable part, and the second actuating part is pivotally assembled between the first and second coupling portions, an operation of the release actuator for unlocking the second adjustable part causing the release actuator to push the second latch to move in sliding contact with the second actuating part, the second actuating part being thereby urged to rotate in a first direction and pull the first actuating part in movement for causing a displacement of the first latch that unlocks the first adjustable part.

13. The child safety seat according to claim 12 , wherein the linking assembly further includes a third spring respectively connected with the first actuating part and the first adjustable part, the third spring being operable to bias the first actuating part to move and pull the second actuating part to rotate in a second direction opposite to the first direction.

14. A child safety seat comprising:
a seat shell for receiving a child, the seat shell having a backrest and a front end opposite to the backrest;
an extension member disposed adjacent to the front end of the seat shell and including a first and a second adjustable part, the first adjustable part being slidably connected with the seat shell, the second adjustable part being pivotally connected with the first adjustable part about a pivot joint, the first adjustable part being slidable relative to the seat shell to increase or reduce a distance between the pivot joint and the front end of the seat shell, and the second adjustable part being rotatable relative to the first adjustable part and the seat shell in front of the front end;
a first and a second latch respectively assembled with the extension member, the first latch being movable to lock and unlock the first adjustable part with respect to the seat shell, and the second latch being operable to rotationally lock and unlock the second adjustable part with respect to the first adjustable part; and
a release actuator assembled with the extension member and operatively connected with the first and second latches, the release actuator being operable to cause the first and second latches to move concurrently for unlocking the first and second adjustable parts.

15. The child safety seat according to claim 14 , wherein the first and second latches are movably linked to each other via a linking assembly that includes a first actuating part disposed adjacent to the first latch, a second actuating part disposed adjacent to the second latch, and a wire respectively connected with the first and second actuating parts, an operation of the release actuator causing the second latch to urge the second actuating part to move so th
