Abstract

A child seat includes a seat shell, and an anchoring system assembled with the seat shell. The anchoring system includes a housing, a latch assembled in the housing, a first and a second strap respectively routed through the housing, and two anchor fasteners respectively secured with the first and second straps at a rear of the seat shell. The housing has a central axis, and a first and a second opening spaced apart from each other along the central axis. The latch is movable along the central axis relative to the housing, and has two clamping surfaces facing two inner surfaces of the housing. The latch is operable to clamp the first and second straps respectively between the two inner surfaces and the two clamping surfaces. The first and second straps extend outside the seat shell at the rear, and also at two opposite lateral sides of the seat shell.

Claims

1. A child seat comprising:

a seat shell; and

an anchoring system assembled with the seat shell, the anchoring system including;

a housing having a central axis, and a first and a second opening spaced apart from each other along the central axis;

a latch assembled in the housing and movable along the central axis relative to the housing, the latch having two clamping surfaces facing two inner surfaces of the housing;

a first strap and a second strap respectively routed through the first and second openings of the housing; and

two anchor fasteners respectively secured with the first and second straps at a rear of the seat shell;

wherein the latch is operable to clamp the first and second straps respectively between the two inner surfaces of the housing and the two clamping surfaces, the first strap extending outside the seat shell at the rear and a first lateral side of the seat shell, and the second strap extending outside the seat shell at the rear and a second lateral side opposite the first lateral side.

2. The child seat according to claim 1, wherein the first strap is routed through an interior of the seat shell and extends outside the seat shell at the rear and a left side, the second strap is routed through the interior of the seat shell and extends outside the seat shell at the rear and a right side.

3. The child seat according to claim 1, wherein the anchoring system includes a spring operable to bias the latch toward the two inner surfaces of the housing to clamp the first and second straps.

4. The child seat according to claim 3, wherein the latch includes a slot arranged between the two clamping surfaces, the anchoring system further includes a connecting element passing through the slot of the latch, and the spring is disposed in the slot with two ends of the spring being respectively connected with an inner sidewall of the slot and the connecting element.

5. The child seat according to claim 1, wherein the two anchor fasteners include hook or loop structures.

6. The child seat according to claim 1, wherein the two clamping surfaces respectively include protruding teeth.

7. The child seat according to claim 6, wherein the teeth protrude inclined toward the second opening.

8. The child seat according to claim 1, wherein the latch includes an actuating portion, the actuating portion being operable to drive displacement of the latch toward an outside of the second opening such that the latch unclamps the first and second straps, whereby the first and second straps are movable relative to the housing and the latch for adjustment.

9. The child seat according to claim 8, further including a third strap connected with the actuating portion.

10. The child seat according to claim 9, wherein the third strap extends outward from a front of the seat shell.

11. The child seat according to claim 1, wherein the two clamping surfaces are inclined symmetrical relative to the central axis, a distance between the two clamping surfaces gradually increasing from the first opening toward the second opening.

12. The child seat according to claim 1, wherein the housing is affixed adjacent to the rear of the seat shell.

13. The child seat according to claim 1, wherein the first and second straps are adjustable independently from each other.

14. The child seat according to claim 1, wherein the first strap is entirely formed from a first single webbing material, the second strap is entirely formed from a second single webbing material separate from the first strap.

15. The child seat according to claim 1, wherein respective portions of the first and second straps extending outward from the first and second openings of the housing are routed along a transversal axis of the seat shell and substantially perpendicular to the central axis.

16. A child seat comprising:

a seat shell;

a housing fixedly secured inside the seat shell, the housing having a central axis, and a first and a second opening spaced apart from each other along the central axis;

a first strap and a second strap respectively routed through the first and second openings of the housing; and

two anchor fasteners respectively secured with the first and second straps at a rear of the seat shell;

a latch assembled in the housing and movable along the central axis relative to the housing, the latch having two clamping surfaces facing two inner surfaces of the housing; and

a third strap connected with the latch;

wherein the latch is operable to clamp the first and second straps respectively between the two inner surfaces of the housing and the two clamping surfaces, and the third strap is operable to displace the latch in a direction that releases the first and second straps for adjustment.

17. The child seat according to claim 16, wherein the first strap extends outside the seat shell at the rear and a left side of the seat shell, and the second strap extends outside the seat shell at the rear and a right side of the seat shell, and the third strap extends outward from a front of the seat shell.

18. The child seat according to claim 16, further including a spring operable to bias the latch toward the two inner surfaces of the housing to clamp the first and second straps.

19. The child seat according to claim 16, wherein the housing is affixed adjacent to the rear of the seat shell.
