Abstract

A child safety seat includes a seat shell having a backrest portion, a headrest adjustable along a front surface of the backrest portion, a shoulder strap, and a panel assembled at the front surface. The shoulder strap is formed from a webbing material that passes through the front surface and extends at a front side of the backrest portion. The panel can cover a region of the backrest portion that becomes uncovered by the headrest at the front surface as a result of the headrest being adjusted downward. Moreover, the seat can include a transversal bar affixed with the backrest portion, and a latch located below the transversal bar. The latch has a locking structure operable to engage with the backrest portion to hold the headrest in place, the latch being assembled with the headrest about a pivot axis located between the transversal bar and the locking structure.

Claims

1. A child safety seat comprising:

a seat shell having a backrest portion, the backrest portion having a front surface, and a slot opened on the front surface;

a headrest adjustable along the front surface of the backrest portion;

a shoulder strap assembled with the seat shell, the shoulder strap being defined from a webbing material that passes through the slot and extends at a front side of the backrest portion; and

a panel assembled at the front surface, the panel being configured to cover a region on the front surface of the backrest portion that extends above the headrest when the headrest is adjusted downward.

2. The child safety seat according to claim 1, wherein the slot has an upper rim edge, and the region covered with the panel includes the upper rim edge.

3. The child safety seat according to claim 1, wherein the region of the backrest portion covered with the panel includes a portion of the slot located above the headrest.

4. The child safety seat according to claim 1, wherein the region that is covered by the panel is gradually reduced as the headrest is adjusted from a lowermost position toward a top end of the backrest portion.

5. The child safety seat according to claim 1, wherein the panel has a first end portion connected with the seat shell, and a second end portion connected with the headrest.

6. The child safety seat according to claim 5, wherein the panel is made of a flexible material that is folded over itself.

7. The child safety seat according to claim 5, wherein the panel is made of a flexible material, and the headrest is provided with a winding drum to which is connected the second end portion of the panel, the winding drum being operable to wind at least partially the panel to keep the panel adequately tensioned when the headrest moves relative to the backrest portion.

8. The child safety seat according to claim 1, wherein the seat shell is provided with a winding drum, and the panel is made of a flexible material having an end portion connected with the winding drum, the winding drum being operable to wind a slack of the panel to keep the panel adequately tensioned when the headrest moves relative to the backrest portion.

9. The child safety seat according to claim 1, wherein the panel is made of a fabric material.

10. The child safety seat according to claim 1, wherein the webbing material is routed through the backrest portion, and wraps around a shaft that is affixed with the backrest portion at a location above the slot.

11. The child safety seat according to claim 1, wherein the headrest includes a latch movable along with the headrest and biased to engage with the backrest portion to hold the headrest in place relative to the backrest portion, the webbing material passing through the latch.

12. A child safety seat comprising:

a seat shell having a backrest portion, the backrest portion having a front surface, and a slot opened on the front surface;

a headrest adjustable along the front surface of the backrest portion;

a shoulder strap assembled with the seat shell, the shoulder strap being defined from a webbing material that passes through the slot and extends at a front side of the backrest portion; and

a panel assembled at the front surface, the panel covering a portion of the slot that extends above the headrest as the headrest is adjusted relative to the backrest portion.

13. The child safety seat according to claim 12, wherein the panel has a first end portion connected with the seat shell, and a second end portion connected with the headrest.

14. The child safety seat according to claim 13, wherein the panel is made of a flexible material that is folded over itself.

15. The child safety seat according to claim 13, wherein the panel is made of a flexible material, and the headrest is provided with a winding drum to which is connected the second end portion of the panel, the winding drum being operable to wind at least partially the panel to keep the panel adequately tensioned when the headrest moves relative to the backrest portion.

16. The child safety seat according to claim 12, wherein the seat shell is provided with a winding drum, and the panel is made of a flexible material having an end portion connected with the winding drum, the winding drum being operable to wind a slack of the panel to keep the panel adequately tensioned when the headrest moves relative to the backrest portion.

17. The child safety seat according to claim 12, wherein the panel is made of a fabric material.

18. The child safety seat according to claim 12, wherein the headrest includes a latch movable along with the headrest and biased to engage with the backrest portion to hold the headrest in place relative to the backrest portion, the webbing material passing through the latch.

19. A child safety seat comprising:

a seat shell having a backrest portion, the backrest portion having a front surface, a slot opened on the front surface, and a transversal bar affixed with the backrest portion;

a headrest adjustable along the front surface of the backrest portion;

a latch assembled with the headrest at a position vertically below the transversal bar, wherein the latch has a locking structure operable to engage with the backrest portion to hold the headrest in place, and the latch is assembled with the headrest about a pivot axis that is located between the transversal bar and the locking structure, the latch further including a slit located between the pivot axis and the locking structure; and

a webbing material assembled with the seat shell, wherein the webbing material wraps around the transversal bar, is routed through the slit of the latch, passes through the slot and extends at a front side of the backrest portion.

20. The child safety seat according to claim 19, wherein the webbing material forms a shoulder strap.

21. The child safety seat according to claim 19, further including an adjusting part movably assembled with the latch adjacent to the slit, the webbing material passing through the adjusting part and the slit, and the adjusting part being movable along a length of the slit to modify a transversal position of the shoulder strap relative to the backrest portion.

22. The child safety seat according to claim 19, wherein the webbing material extending downward from the transversal bar wraps around a portion of the latch adjacent to the pivot axis, and passes through the latch and the slot to extend at the front side of the backrest portion.

23. The child safety seat according to claim 19, further including a panel connected with the seat shell, when the headrest is adjusted to a position that is lower relative to a top end of the backrest portion, the panel covering a region of the backrest portion extending between the headrest and the top end of the backrest portion.

24. The child safety seat according to claim 19, wherein the latch includes a catch finger and a locking structure respectively configured to engage with the backrest at two spaced-apart locations, when the latch is turning to a locking state, the catch finger first engages with the backrest to prevent downward displacement of the headrest, and the locking structure subsequently completes its engagement with the backrest.
