Abstract

A child seat includes a seat shell, a retractor assembly connected with the seat shell, two anchor strap portions extending outward from a rear of the seat shell, and an adjustment strap extending outside the seat shell. Each of the two anchor straps is provided with a fastener operable to attach with an anchor structure of a vehicle. The two anchor strap portions extend outward from a rear of the seat shell, and are provided with two fasteners operable to attach with an anchor structure of a vehicle, the anchor strap portions being connected with the retractor assembly. The adjustment strap is operable to actuate the retractor assembly to retract the anchor strap portions toward an interior of the seat shell.

Claims

1. A child seat comprising:

a seat shell;

a retractor assembly connected with the seat shell, the retractor assembly including a spool assembled with the seat shell;

two anchor strap portions extending outward at a rear of the seat shell and provided with two fasteners operable to attach with an anchor structure of a vehicle, at least one of the anchor strap portions being connected with the spool of the retractor assembly; and

an adjustment part connected with the retractor assembly and accessible from outside the seat shell, wherein the adjustment part includes an adjustment strap separate from the anchor strap portions that extends outside the seat shell for operation, the adjustment strap having an end portion connected with the spool, the adjustment strap being pulled away from the seat shell to drive a displacement of the spool that retracts the at least one of the anchor strap portions toward the seat shell, and pulling the at least one of the anchor strap portions away from the seat shell draws the adjustment strap toward the seat shell, the at least one of the anchor strap portions being thereby coupled in movement to the adjustment strap, wherein the spool is rotatable to wind and unwind at least partially the adjustment strap and the at least one of the anchor strap portions, more of the adjustment strap becoming wrapped around the spool when the spool rotates for unwinding at least partially the at least one of the anchor strap portions.

2. The child seat according to claim 1, wherein the spool rotates about a pivot axis that extends transversal relative to the seat shell.

3. The child seat according to claim 2, wherein the adjustment strap is connected with the spool at a location between the respective connections of the two anchor strap portions with the spool, the adjustment strap being operable to drive a rotation of the spool for winding at least partially the two anchor strap portions.

4. The child seat according to claim 1, wherein the spool rotates about a pivot axis that extends along a vertical direction relative to the seat shell.

5. The child seat according to claim 1, wherein the adjustment part further includes a lock, the lock is spaced apart from the retractor assembly, the adjustment strap passing through the lock and extending outside the seat shell, the lock when in a locking state blocks a sliding movement of the adjustment strap through the lock, and the lock when in an unlocking state allows sliding of the adjustment strap through the lock.

6. A child seat comprising:

a seat shell;

a retractor assembly connected with the seat shell, the retractor assembly including a rotary member;

an anchor strap portion extending outward at a rear of the seat shell and provided with a fastener operable to attach with an anchor structure of a vehicle, the anchor strap portion being connected with the rotary member of the retractor assembly; and

an adjustment strap extending outside the seat shell and having an end portion connected with the rotary member, the adjustment strap being pulled away from the seat shell to apply a force on the rotary member that drives a rotation of the rotary member in a first direction for retracting the anchor strap portion toward the seat shell, and pulling the anchor strap portion away from the seat shell causes a rotation of the rotary member in a second direction opposite to the first direction that retracts the adjustment strap toward the seat shell, the anchor strap portion being thereby coupled in movement to the adjustment strap, wherein the rotary member is rotatable to wind and unwind at least partially the adjustment strap and the anchor strap portion, more of the adjustment strap becoming wrapped around the rotary member when the rotary member rotates for unwinding at least partially the anchor strap portion.

7. The child seat according to claim 6, further including a lock assembled with the adjustment strap, the lock when in a locking state blocks a sliding movement of the adjustment strap through the lock, and the lock when in an unlocking state allows sliding of the adjustment strap through the lock.

8. The child seat according to claim 6, wherein the adjustment strap extends at a side other than the rear of the seat shell.

9. The child seat according to claim 6, wherein the rotation of the rotary member driven by pulling the adjustment strap causes the anchor strap portion to wrap at least partially around the rotary member.
