100021 1. Field of the Invention

[0003] The present inventions relate to child seats provided with anchoring harnesses.

[0004] 2. Description of the Related Art

[0005] Conventionally, an automobile vehicle has seatbelts provided at the front and rear seats. The seatbelt generally includes shoulder and lap straps that may be fastened with an anchor point of the vehicle to restrain and protect the occupant in case of collision or sudden stop of the vehicle. However, the use of the vehicle seatbelt is not adapted for a young child who has a smaller body and may not be able to sustain the pressure applied by the seatbelt. As a result, safety legislations require the use of a child safety seat for seating a young child in a vehicle. The seatbelt of the vehicle can be used to hold the child safety seat in place, whereas the child safety seat has an internal child restraint harness more adapted to provide protection for the young child.

[0006] For a child of higher age, the size of the child safety seat may not be adapted to the child having a larger body. In this case, a booster seat may be used to increase the height at which the child sits, and the seatbelt of the vehicle can be used to properly restrain the child. Unlike the child safety seat, the booster seat is usually p'aced on the vehicle passenger's seat without attachment, When collision occurs, the booster seat may be subject to displacement, which may adversely affect the restraining protection provided by the seatbelt, [0007] Accordingly, there is a need for a child seat that can be securely held in place when installed in a vehicle, and address at least the foregoing issues.

100381 Figures 5A and SB are respectively perspective and enlarged views illustrating another embodiment of a child seat 1 The child seat I can include a seat portion 12, two armrests 14 and an anchoring harness 56. The seat portion 12 and the armrest N may be as described previously.

100391 The anchoring harness 56 can be likewise assembled with the seat portion 12 near the rear edge 12C by routing through the openings 18, The anchoring harness 56 can include two fasteners 562, a strap 564 and a length adjustment device 566. The strap 564 can be made of one or more piece of webbing material. The strap 564 can have two opposite ends respectively connected with the fasteners 562.

100401 The length adjustment device 566 can be fixedly secured with the seat portion 12. As shown, the length adjustment device 566 can include a frame 5660, and two buttons 5664. The frame 5660 can be affixed with the seat portion 12 at a position between the two openings 18. The seat portion 12 and the frame 5660 can be viewed as a unitary block. The frame 5660 can have two sets of openings 5662 transversally spaced apart from each other by a material portion 5660F, each set including two openings 5662 respectively disposed at upper and lower surfaces of the frame 5660.

100411 Figures SC arid SD are schematic cross-sectional views illustrating more details of the length adjustment device 566. The two buttons 5664 can be assembled through the frame 5660 respectively adjacent to the two sets of openings 5662, and can move along the transversal axis of the frame 5660. A spring 5666 can be assembled in the frame 5660 between the two buttons 5664, two opposite ends of the spring 5666 being respectively connected with the buttons 5664. Each button 5664 can include two holes 5668 respectively provided at two opposite regions of the button 5664.

When the buttons 5664 are assembled with the frame 5660, the holes 5668 of each button 5664 can be located adjacent one set of openings 5662. The two buttons 5664 can be movable relative to the frame 5660 so that the holes 5668 can be respectively aligned or misaligned with respect to the two sets of openings 5662.

100421 The strap 564 can be routed through the openings 18, the openings 5662 of the frame 5660 and the holes 5668 of the buttons 5664 so that an intermediate portion of the strap 564 can form a loop 5642 folding around the material portion 12F (e.g., from the upper side) between the two openings 18.

[0043] It is noted that some variant methods for routing the strap 564 may be possible. For example, the strap 564 may also be routed through the openings 5662 of the frame 5660 and the holes 5668 of the buttons 5664, and remain outside the openings 1 8.

[0044] Referring to Figures SC and SD, the length adjustment device 566 can be operable to adjust the strap 564. As shown in Figure SC, the spring 5666 can oppositely bias the buttons 5664 toward an outside of the frame 5660 so that the holes 5668 of each button 5664 are misaligned with one corresponding set of the openings 5662, As a result, the strap 564 can be tightly clamped between the rims of the holes 5668 and the openings 5662 at two spaced-apart locations of the frame 5660, which blocks sliding of the strap 564 through the length adjustment device 566. The two strap segments 564A extending at the rear of the seat portion 12 can be thereby fixed in length.

[0045] Referring to Figure SD, the buttons 5664 can be pressed to move toward each other to compress the spring 5666. As the buttons 5664 move relative to the frame 5660, the holes 5668 of each button 5664 can become substantially aligned with one corresponding set of the openings 5662 of the frame 5660 to unclamp the strap 564.

Then the strap 564 can slide through the buttons 5664 and the frame 5660 for adjusting the lengths of the two strap segments 564A, For example, the length of the loop 5642 can be increased when the two strap segments 564A are shortened, and shortened when the two strap segments 564A are in increased in length.

100461 Examples of the child seats described herein can have different construction of anchoring harnesses that can attach with an anchorage fixture of a vehicle. The anchoring harnesses can be easily assembled with the seat portion of the child seat, and adjustable in length for facilitating its attachment with the anchorage fixture.
