Description

Technical Field

[0001] This invention relates to a harness assembly, and more particularly to a harness assembly with multiple adjustment modes. This invention also relates to a child safety seat. Background Technology

[0002] A child safety seat is a seat specifically designed for children. By assembling a child safety seat inside a car, children can sit in it, thereby restraining them and ensuring their safety.

[0003] Existing child safety seats typically consist of a base and a seat mounted on the base. ISOFIX connectors are located on one side of the base, and the top tether is secured to the back of the seat. The child safety seat is secured by connecting the top tether and ISOFIX connectors to the corresponding mounting points inside the car. The ISOFIX connectors are secured on both sides of the base, while the top tether is secured at the top of the child safety seat. With these three points of attachment, the child safety seat is firmly fixed to the car seat and will not flip over in the event of an impact.

[0004] After the top tether is in place, it needs to be tightened to securely connect it to the other parts of the child safety seat. However, traditional methods of adjusting the top tether length only allow adjustment in one direction, which may be difficult to apply sufficient tightening force in different types of vehicles due to space constraints. Therefore, there is a need for a tether assembly that can conveniently tighten the top tether in multiple ways, and a child safety seat with such a tether assembly. Summary of the Invention

[0092] To further illustrate the principles and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, the embodiments are for illustrative and explanatory purposes only and should not be used to limit the scope of patent protection of the present invention.

[0093] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0094] The following is a more detailed description of various concepts and implementations of tethering assemblies and child safety seats, the seat of which can rotate between rear-facing, lateral, and forward-facing positions for ease of use. It should be understood that the various concepts described above and discussed in more detail below can be implemented in multiple ways. Examples of specific implementations and applications are primarily for illustrative purposes, enabling those skilled in the art to implement implementations and alternatives that are obvious to them.

[0095] Figure 1 This is a side view of one embodiment of the child safety seat of this application. Figure 2 This is a plan view of one embodiment of the child safety seat of this application.

[0096] The child safety seat 1 may include a base 10, a seat 20 disposed above the base 10, and a top bar 30 erected at the rear of the base 10.

[0097] The base 10 may be provided with a rearwardly extending anchoring part 110. The anchoring part 110 may be an ISOFIX type connector (a connector that can be fixed with an ISOFIX interface) and includes two anchoring arms 111.

[0098] The child safety seat 1 may include a harness assembly 40. Optionally, the harness assembly 40 may also be a separate component other than the child safety seat 1. The harness assembly 40 may be a Top Tether type connector (a connector that can be secured to a Top Tether interface).

[0099] The top rod 30 can be fixed to the rear of the base 10. Specifically, the top rod 30 can stand substantially vertically at the rear of the base 10. An opening 330 may be provided on the upper part of the top rod 30. In different embodiments, the top rod 30 may have one or two openings 330. The top strap 410 of the strap assembly 40 (described in detail below) is fixed to the child safety seat 1 via the opening 330. For example, the top strap 410 extends into and is fixed therein through the opening 330.

[0100] In one embodiment, the top rod 30 may include two vertical rods 310 and a fixing part 320, and the top of each of the two vertical rods 310 is provided with an opening 330.

[0101] One end of each of the two straps in the top strap 410 (e.g., connecting strap 412 and adjusting strap 411) can be fixed to the top rod 30 via two vertical rods 310 respectively. One connecting strap 412 and the two adjusting straps 411 of the top strap 410 are connected to each other via two adjusters 430, and the strap fixing part 450 is fixedly or movably connected to one adjusting strap 411, thereby forming the strap assembly 40 as a whole in a Y-shape or V-shape. One end of the aforementioned straps can move a limited distance within the top rod 30.

[0102] One end of two straps (e.g., two connecting straps 412) in the top strap 410 can be fixed to the top rod 30 by two vertical rods 310 respectively. The other ends of the two straps are fixed with two adjusters 430. The two ends of an adjusting strap 411 pass through the two adjusters 430 respectively to form two free ends 4111, and the strap fixing part 450 is fixedly or movably connected to the adjusting strap 411, so that the strap assembly 40 is formed as a whole in a Y-shape or V-shape.

[0103] Two straps (e.g., two connecting straps 412) in the top strap 410 are secured at one end to the top rod 30 via two vertical rods 310. The other ends of these two straps are secured to connectors 460. One end of an adjusting strap 411 is secured to the connector 460. The other end of the adjusting strap 411 can pass through an adjuster 430, and another adjusting strap 411 can pass through another adjuster 430, forming two free ends 4111, thus making the strap assembly 40 generally Y-shaped or V-shaped. The two adjusters 430 can be connected to each other (e.g., via connecting straps 412).

[0104] In one embodiment, the two ends of one of the straps (e.g., connecting strap 412) in the top strap 410 are respectively secured to the top rod 30 by two vertical rods 310. An adjusting strap 411 is fixedly or slidably connected to the aforementioned strap (optionally, other adjusting straps 411, connecting straps 412, and adjusters 430 are also connected), thereby forming the strap assembly 40 in a T-shape overall.

[0105] In one embodiment, such as Figure 6 As shown, the top rod 30 may include two vertical rods 310 and a fixing part 320.

[0106] Specifically, the top rod 30 includes: two vertical rods 310, which are symmetrically erected at the rear of the base 10; a fixing part 320, which connects the top ends of the two vertical rods 310, and a receiving part 340 is provided in the center of the lower surface of the fixing part 320.

[0107] One end of one of the straps in the top strap 410 (e.g., connecting strap 412) can be secured to the top rod 30. One end of the aforementioned strap can move a limited distance within the top rod 30.

[0108] In one embodiment, such as Figure 7 As shown, the top rod 30 may include a vertical rod 310 and a receiving portion 340.

[0109] One end of one of the straps in the top strap 410 (e.g., connecting strap 412) can be secured to the top rod 30. One end of the aforementioned strap can move a limited distance within the receiving portion 340. In this application, the two adjusters 430 can be replaced by one bidirectional adjuster 440 (described below). One adjuster 430 can also be replaced by one bidirectional adjuster 440.

[0110] The vertical rod 310 and the fixing part 320 can be made of different materials. For example, the vertical rod 310 can be made of metal, while the fixing part 320 can be made of plastic.

[0111] The seat 20 is rotatably mounted on the base 10 and can rotate relative to the base 10 by an angle along an axis that is substantially perpendicular to the upper surface of the base 10. The lower surface of the base 10 may form an angle with the upper surface, causing the seat 20 to tilt forward.

[0112] Figure 8 This is a schematic diagram of one embodiment of the lacing assembly of this application.

[0113] The harness assembly 40 may include: at least two adjusters 430; a top harness 410, secured to the child safety seat 1, and passing through the at least two adjusters 430 to form free ends 4111 equal in number to the at least two adjusters; and a harness fastener 450, coupled to the top harness 410 and capable of being secured to the vehicle. Each of the at least two adjusters 430 is capable of locking and releasing the top harness 410 passing through it.

[0114] In one embodiment, the lacing assembly 40 has two adjusters 430. However, the lacing assembly 40 may have more than two adjusters 430.

[0115] like Figure 12As shown, the connecting strap 412 can extend into the regulator 430 from one side, pass around a fixing part on the regulator 430, and then extend out of the regulator 430 from the bottom. In this way, the connecting strap 412 can be fixed to the regulator 430. The adjusting strap 411 (for example, connected to the strap fixing part 450) enters the regulator 430 from the opening on the bottom side of the regulator 430, passes around a part of the button 432, and passes downward through the gap formed between the button 432 and the regulator housing 431, and finally extends out from the left side of the regulator 430 to form a free end 4111. When the button 432 is pressed to the right, the gap formed between the button 432 and the regulator housing 431 increases, allowing the adjusting strap 411 to move freely relative to the regulator 430. When button 432 is released, the gap between button 432 and regulator housing 431 decreases (e.g., by means of the spring force of the return spring), causing the adjustment band 411 to be clamped (locked) by button 432 and regulator housing 431 and unable to move freely relative to regulator 430.

[0116] Figure 4 This is a plan view of the adjuster of the tether assembly of this application. Figure 5 This is a perspective view of the adjuster of the lacing assembly of this application.

[0117] In one embodiment, one end of the regulator 430 may be designed as an adjustment end, which may be designed as a button, for example.

[0118] In another embodiment, the regulator 430 may include an regulator housing 431 and a button 432. The button 432 may have an opening on one side, for example, above or below the button 432. A webbing (e.g., an adjustment webbing 411 described below) may enter the interior of the button 432 through this opening and pass through a variable-width slit defined by the button 432 and the housing 431, and then extend out of the opening.

[0119] The regulator 430 may have a reset mechanism, such as a spring, so that when the button 432 is not pressed, the slit tends to narrow, thereby locking the webbing passing through the regulator 430 and preventing it from moving relative to the regulator 430. Moreover, when the button 432 is pressed, the slit tends to widen, thereby allowing the webbing passing through the regulator 430 to move relative to the regulator 430.

[0120] The adjuster 430 may also have other structures, for example, the webbing may enter from one side of the adjuster 430 and extend from the other side. The specific structure of the adjuster 430 is not limited here, as long as it enables the adjuster to adjust the length of the webbing passing through it and can lock the webbing when adjustment is not required.

[0121] The other side of the adjuster 430 may be provided with a fixing part so that other webbing can be fixedly connected to the adjuster 430.

[0122] The regulator 430 may have an opening to reveal a marking indicating whether the regulator 430 is locked or released. An example of this marking could be a different colored label.

[0123] The tether fixing part 450 may be a hook (or hook-shaped anchor) which is fixedly or slidably disposed at the distal end of the top tether 410.

[0124] The two adjusters 430 of the harness assembly 40 can be arranged in opposite directions, such that the two free ends 4111 formed by the top harness 410 passing through the two adjusters 430 extend in opposite directions. It is understood that since the top harness 410 is flexible, the orientation of the adjusters 430 provided on the top harness 410 will change. Therefore, the above-mentioned arrangement of the two adjusters 430 in opposite directions means that after the harness assembly 40 secures the child safety seat 1 to the vehicle, in the taut state of the harness assembly 40, the two adjusters 430 are arranged in a substantially opposite manner. The two free ends 4111 in opposite directions means that after the harness assembly 40 secures the child safety seat 1 to the vehicle, the two free ends 4111 extend from the two adjusters 430 in substantially opposite directions initially, because due to gravity, the two free ends 4111 will, for example, be in a drooping posture. Optionally, the harness assembly 40 has only one adjuster 430.

[0125] The two adjusters 430 of the lacing assembly 40 can be arranged in the same direction, such that the two free ends 4111 formed by the top lacing 410 passing through the two adjusters 430 extend in the same direction.

[0126] like Figure 8 As shown, in one embodiment, the top strap 410 may have a first adjustment strap 411a, a second adjustment strap 411b, a first adjuster 430a, a second adjuster 430b, and a connecting strap (or first connecting strap) 412. The first adjustment strap 411a, the second adjustment strap 411b, and the connecting strap 412 may be associated with each other (e.g., directly connected or connected to each other via the first adjuster 430a and the second adjuster 430b) to form the top strap 410.

[0127] One end of the connecting strap 412 is fixed to one side of the top rod 30 (e.g., inside a vertical rod 310), while the other end of the connecting strap 412 is fixed to the first adjuster 430a.

[0128] One end of the first adjustment band 411a is fixed to the other side of the top bar 30 (e.g., inside another vertical bar 310), while the other end of the first adjustment band 411a passes through the second adjuster 430b to form a free end 4111 extending toward the child safety seat 1.

[0129] One end of the second adjustment strap 411b is fixed to the second adjuster 430b, while the other end of the second adjustment strap 411b passes through the first adjuster 430a to form a free end 4111 extending away from the child safety seat 1.

[0130] One end of the strap fixing part 450 can be slidably or fixedly connected to the second adjusting belt 411b, and the other end of the strap fixing part is formed as a hook.

[0131] In this way, the tie assembly 40 can be tightened in two opposite directions, making the installation of the tie assembly 40 more convenient. Furthermore, the ease of applying tightening force ensures that the tie assembly 40 is tightened, thereby improving the safety of the tie assembly. In addition, the tie assembly 40 has a greater range of length adjustments.

[0132] Optionally, in this embodiment, the top strap 410 may have only one adjuster 430. Optionally, in this embodiment, the top strap 410 may have three adjusters 430. Optionally, the adjuster 430 may be a two-way adjuster (as described below).

[0133] like Figure 9 As shown, in one embodiment, the top strap 410 may have a first adjustment strap 411a, a second adjustment strap 411b, a first adjuster 430a, a second adjuster 430b, a first connecting strap 412a, and a second connecting strap 412b.

[0134] The two ends of the first connecting band 412a are respectively fixed to both sides of the top rod 30, for example, fixed to the two vertical rods 310 or inside them.

[0135] One end of the first adjustment strap 411a is slidably or fixedly connected to the first connecting strap 412a, and the other end of the first adjustment strap 411a passes through the first adjuster 430a to form a free end 4111 extending toward the child safety seat 1.

[0136] The two ends of the second connecting band 412b are respectively fixed to the first regulator 430a and the second regulator 430b.

[0137] One end of the second adjustment strap 411b passes through the second adjuster 430b to form a free end 4111 extending away from the child safety seat 1, and the other end of the second connecting strap 412b is fixed with a strap fixing part 450.

[0138] In this way, the tie assembly 40 occupies less space, making it easier to install in relatively narrow carriages.

[0139] Optionally, in this embodiment, the top strap 410 may have only one adjuster 430. Optionally, in this embodiment, the top strap 410 may have three adjusters 430. Optionally, one adjuster 430 may be a two-way adjuster (as described below).

[0140] like Figure 10 As shown, the strap assembly may further include a connector 460 for simultaneously connecting two connecting straps 412 and an adjusting strap 411 together. The two connecting straps 412 can be fixed to one side of the connector 460, while the adjusting strap 411 can be fixed to the other side of the connector 460. The connector 460 may be a metal sheet with three elongated holes formed thereon.

[0141] Optionally, in this embodiment, the top strap 410 may have only one adjuster 430. Optionally, in this embodiment, the top strap 410 may have three adjusters 430. Optionally, one adjuster 430 may be a two-way adjuster (as described below).

[0142] Figure 11 This is a schematic diagram of yet another embodiment of the lacing assembly of this application.

[0143] The harness assembly 40 may include a first adjuster 430a, a second adjuster 430b, and an adjustment strap 411. The first adjuster 430a and the second adjuster 430b are arranged in the same direction. The two ends of the adjustment strap 411 pass through the first adjuster 430a and the second adjuster 430b, respectively, to form two free ends 4111 extending in the same direction (away from the child safety seat). The first adjuster 430a and the second adjuster 430b may be secured to both sides of the top bar 30 via a connecting strap 412. The harness fixing part 450 is slidably connected to the adjustment strap 411.

[0144] In this way, when the child safety seat 1 is installed in the right-side or left-side seat of the vehicle, the harness assembly 40 can be adjusted via the adjuster on the side closer to the seat, making it easier to apply force. Adjustments made via two adjusters have a similar effect. Furthermore, the two adjusters allow for a wider range of adjustable length for the harness assembly 40.

[0145] Optionally, in this embodiment, the top strap 410 may have only one adjuster 430. Optionally, in this embodiment, the top strap 410 may have three adjusters 430. Optionally, one adjuster 430 may be a two-way adjuster (as described below).

[0146] Figure 13This is a schematic diagram of an embodiment of the child safety seat harness assembly 40 of this application. The harness assembly 40 may include a top harness 410, an adjuster 430, and a harness fastener 450. The top harness 410 may include an adjusting strap 411 and a connecting strap 412. The adjusting strap 411 may pass through the adjuster 430 and extend to a free end 4111. The adjuster 430 may have a button. When the button is not pressed, the adjuster 430 locks the adjusting strap 411, and when the button is pressed, the adjuster 430 releases the adjusting strap 411. At this time, pulling the free end 4111 can shorten the length of the adjusting strap 411, and pulling the adjusting strap 411 can increase the length of the adjusting strap 411.

[0147] Figure 14 This is a schematic diagram of another embodiment of the harness assembly 40 of the child safety seat of this application. The harness assembly 40 may have two adjusters 430. The two adjusters 430 may be arranged in opposite directions. The top harness 410 may include two adjusting straps 411 and a connecting strap 412. The connecting strap 412 is connected between the two adjusters 430. The two adjusting straps 411 pass through the two adjusters 430 respectively to form two free ends 4111 facing opposite directions, such that the length of the harness assembly 40 can be adjusted in two opposite directions by pulling the two free ends 4111.

[0148] In one embodiment, the strap fixing part 450 is fixed to the end of one of the two adjusting straps 411. The other of the two adjusting straps 411 is fixed to the top rod 30.

[0149] In another embodiment, the strap fixing part 450 is slidably connected to one of the two adjusting straps 411. The other of the two adjusting straps 411 is fixed to the top rod 30.

[0150] In yet another embodiment, the lacing assembly 40 further includes a bidirectional adjuster 441. The bidirectional adjuster 441 is capable of adjusting the length of the lacing assembly 40 in two opposite directions. In other words, two adjusting straps 411 can pass through the bidirectional adjuster 441 from both ends to form two free ends 4111 facing opposite directions, such that the length of the lacing assembly 40 can be adjusted in two opposite directions by pulling the two free ends 4111.

Figure 16 This is a schematic diagram of another embodiment of the harness assembly of the child safety seat of this application. Figure 15 and Figure 16 The embodiments shown are respectively with Figure 13 and Figure 14The embodiment shown is similar, except that a bidirectional regulator 440 is used instead of the two regulators 430 and the connecting strip 412.

[0153] The bidirectional regulator 440 may include: a regulator housing 441 having two first openings facing opposite directions; two buttons 442 respectively disposed at the two first openings and movable in the direction of entering and exiting the regulator housing 441; a retaining plate 443 fixed to the bottom of the regulator housing 441 and forming two second openings; and two locking members 444 disposed inside the regulator housing 441 and movable together with the two buttons 442 to form a locked position and a released position, wherein two straps (e.g., top straps 410) can enter the regulator housing 441 through the two second openings, pass through the gap between the two locking members 444 and the retaining plate 443, and extend out of the regulator housing 441 to form free ends extending in two opposite directions, and wherein, in the locked position, the two locking members 444 and the retaining plate 443 clamp the two straps respectively, while in the released position, the two locking members 444 and the retaining plate 443 allow the two straps to move.

[0154] A spring may be provided between the two buttons 442 to provide a restoring force to the regulator housing 441 to each button 442.

[0155] Two tension indicator windows 445 may be formed on the upper surface of the regulator housing 441 to indicate whether the two straps are tensioned. Different positions on the upper surfaces of the two buttons 442 may be marked with different colors. Thus, when the buttons 442 are in the locked position, the tension indicator windows 445 show one color (e.g., green) on the upper surface of the buttons 442, and when the buttons 442 are in the released position, the tension indicator windows 445 show another color (e.g., red) on the upper surface of the buttons 442. Alternatively, the tension indicator windows 445 may also be provided in other locations on the regulator housing 441, such as the sides, bottom, or both ends, and this application is not limited thereto. Information may also be provided in other ways within the tension indicator windows 445, such as lines or graphic markings, and this application is not limited thereto. The tension indicator windows 445 may also be formed of a transparent material to allow the interior of the regulator housing 441 to be seen.

[0156] The bidirectional adjuster 440 allows for adjustment of the length of the top strap 410 in different directions.

[0157] like Figure 25 As shown, when the top strap 410 passes through the bidirectional adjuster 440, it first enters the adjuster housing 441 upwards from the opening of the locking member 444, and then passes upwards through the inside of the retaining plate 443 and the button 442. Figure 25 (in the middle), then around the fixing piece 443, and on the outside of the fixing piece 443 ( Figure 25 The regulator housing 441 extends downwards again from the left and right sides of the middle section, passing through the gap between the fixing piece 443 and the locking piece 444, and finally extends outwards from the lower part of the locking piece 444.

[0158] In this way, when the top strap 410 is tightened, the top strap 410 will be clamped between the locking member 444 and the fixing piece 443 (because when the adjusting belt 111 is tightened, the top strap 410 pulls the fixing piece 443 outward, making the fixing piece 443 and the locking member 444 closer), thus positioning the top strap 410. When it is necessary to adjust the length of the top strap 410, press the button 442 to move the fixing piece 443 away from the fixing member 444, and the top strap 410 will be loosened, allowing for length adjustment.

[0159] When using the bidirectional adjuster 440, the two top straps 410 passing through the bidirectional adjuster 440 extend into the top rod 30 and connect to the strap fixing part 450, thereby realizing a strap assembly 40 whose length can be adjusted in different directions.
