[0017] Although the invention has been illustrated and described herein with reference to specific embodiments, the invention should not be limited to the details shown, in particular, various changes can be made to these details, within the scope and range of equivalents of the claims, without departing from the invention.

[0018] The descriptions of directions such as "front", "back", "upper", and "lower" contained in this specification are merely for ease of understanding, and the present invention is not limited to these directions and can be adjusted according to actual circumstances. Although the present application has been described with reference to a list of exemplary embodiments, the terms used are descriptive and exemplary, rather than limiting.

[0019] A child seat 1 according to the present application will be described generally with reference to Figs. 1 to 10. The child seat 1 includes a base 101 and a seat body 100. The base 101 is attached to a vehicle seat 2, and the seat body 100 is disposed above the base 101. In some embodiments, the base 101 may be disposed facing forward or backward with respect to the vehicle seat 2, and the seat body 100 is also disposed facing forward or backward accordingly. In other embodiments, the orientation of the base 101 with respect to the vehicle seat 2 is fixed, and the seat body 100 can be rotated with respect to the base 101 so as to be disposed facing forward or backward with respect to the vehicle seat 2. The seat body 100 is fastened to the vehicle seat 2 by a seat belt 200 on the vehicle seat 2. In the forward and backward positions of the seat body 100, the seat belt 200 fastens the child seat 1 (particularly the seat body 100) to the vehicle seat 2 through the same engagement point. The engagement point includes a first engagement point and a second engagement point. More specifically, the first engagement point may be the limiting member 140 and the second engagement point may be the clamping member 150 .

[0020] Whether the seat body 100 is used facing forward or backward, the seat belt 200 is disposed to pass through the same engagement point, so that the restraining path of the seat belt 200 for the seat body 100 used facing forward or backward is the same, thereby preventing the child seat 1 from being unable to be stably engaged with the vehicle seat 2 due to misuse of the seat belt 200. This significantly improves the safety of the child seat 1 in use and provides effective and reliable protection for the child.

[0021] The child seat 1 includes a limiting member 140 and a clamping member 150 for engaging with the seat belt 200, and both the limiting member 140 and the clamping member 150 are disposed on the seat body 100. The limiting member 140 is attached to the side of the upper part of the seat body 100 and allows the seat belt 200 to pass through. The clamping member 150 is attached to the side of the seat body 100 and at a position below the limiting member 140 and allows the seat belt 200 to pass through by clamping it. More specifically, the limiting member 140 may be disposed on the upper frame of the seat body 100, and the clamping member 150 is disposed vertically away from the limiting member 140 by, for example, a distance of about one-quarter or one-third of the height of the seat body 100. Depending on the actual situation, the vertical distance between the clamping member 150 and the limiting member 140 can be larger or smaller without affecting the technical effect of the present application.

[0022] In order to stably attach the child seat 1 to the vehicle seat 2 using the seat belt 200, the height of the limiting member 140 is important. The limiting member 140 resists the action force and limits the position of the seat belt 140. Increasing the height of the limiting member 140 enhances its resisting and limiting effects. However, the height of the seat main body 100 also increases. In order to reduce the height of the seat main body 100 and ensure the resisting, limiting and tensioning effects of the seat on the seat belt 200, the clamp member 150 is disposed below the limiting member 140. This helps to maintain the tension of the seat belt 200 and prevent slipping. Besides providing the resisting and limiting effects, the limiting member 140 also guides the seat belt 200. This arrangement ensures that the height of the limiting member 140 is sufficient, resulting in better resisting and limiting the seat belt 200. Additionally, the clamping member 150 prevents slippage of the seat belt 200, maintains tension in the seat belt 200, and prevents slack in the seat belt 200 which could result in improper tensioning of the child seat 1.

[0023] The child seat 1 further includes a passage 130. The passage 130 passes laterally through the rear of the seat body 100 and is located below the clamp member 150. In one embodiment, the passage 130 extends vertically from the clamp member 150 to near the lower end of the seat body 100 and continues to bend forward near the lower end of the seat body 100 to form a vertical portion 131. That is, the seat body 100 includes a seating portion 110 and a backrest frame 120. The backrest frame 120 is attached to the upper and lower ends of the seating portion 110 and is spaced apart from the seating portion 110 between the upper and lower ends to form the passage 130.

[0024] By passing the seat belt 200 laterally through the passage 130, the seat belt 200 can be more securely attached to the child seat 1. Furthermore, the seat belt 200 can be hidden within the passage 130, providing the child seat 1 with a neater appearance.

[0025] In this embodiment, the seat belt 200 can reach the other side of the child seat 1 from one side through the restricting member 140 and / or the clamping member 150 arranged on the one side and the passage 130. However, the passage 130 is not essential. In other embodiments, the backrest frame 120 may not be provided, in which case the passage 130 is not formed between the seating portion 110 and the backrest frame 120, that is, the back of the seating portion 110 is completely open. In this way, the seat belt 200 does not need to pass through the passage 130 and can pass directly from the back of the seating portion 110.

[0026] In this embodiment, two limiting members 140 are provided, and the two limiting members 140 are arranged symmetrically on both sides of the seat body 100 and are close to the upper part of the seat body 100. Two clamping members 150 are provided, and the two clamping members 150 are arranged symmetrically on both sides of the seat body 100 and are located in the center of the upper part of the seat body 100. In other embodiments, the two limiting members 140 on both sides can be arranged asymmetrically, and the two clamping members 150 can also be arranged asymmetrically.

[0027] The symmetrical arrangement of the limiting member 140 and the clamping member 150 allows the seat belt 200 to be attached to either side of the child seat 1 with the same engagement method.

[0028] More specifically, each of the restricting members 140 includes a restricting piece 141 and a slot 143. The restricting piece 141 extends along the upper frame of the seat body 100. Both ends of the restricting piece 141 are attached to the sides of the seat body 100, respectively, and the portion between the both ends is separated from the side of the seat body 100 by a gap. The length of the gap is larger than the width of the seat belt 200, and the thickness of the gap is larger than the thickness of the seat belt 200, forming a restricting space 144 for the entire width of the seat belt 200 to pass through. The slot 143 separates the restricting piece 141 into two parts, and the slot width of the slot 143 is slightly larger than the thickness of the seat belt 200, allowing the seat belt 200 to pass through the slot 143 and enter the restricting space 144 from the outside of the child seat 1.

[0029] The structure of the limiting member 140 allows for easy insertion and removal of the seat belt 200 while also ensuring that the seat belt 200 is securely clamped within the limiting member 140 during a crash.

[0030] Each clamp member 150 includes a case 151, a clamp portion 152, and an elastic member 153. The case 151 is embedded in a side surface of the seat body 100 and at least partially houses other components of the clamp member 150. With reference to Figs. 12 to 15, the case 151 has a structure surrounded by three sides, that is, a front wall 151a, a top wall 151b, and a rear wall 151c that are connected to each other, and also has a slit 156 that allows the seat belt 200 to enter the case 151. The clamp portion 152 is rotatable between an open position and a closed position around a rotation shaft 159 that is substantially vertical to the case 151. When the clamp portion 152 is in the open position, a space into which the seat belt 200 can be inserted is formed between the clamp portion 152 and the case 151. When clamp portion 152 is in the closed position, clamp portion 152 abuts against case 151 and can clamp seat belt 200 inserted between clamp portion 152 and case 151. Elastic member 153 is disposed between case 151 and clamp portion 152, and biases clamp portion 152 toward the closed position.

[0031] The structure of the clamp member 150 allows the seat belt 200 to be attached with a simple operation, and also allows the seat belt 200 to extend through the clamp member 150 and into the passage 130 of the child seat 1.

[0032] In one embodiment, the clamp portion 152 is provided with an engagement tooth 155 on an edge portion that abuts against the case 151, and when the clamp portion 152 is in the closed position, the engagement tooth 155 abuts against the case 151 to strengthen the clamping of the seat belt 200. An actuating portion 154 is provided at one end of the clamp portion 152, which applies an external force for rotating the clamp portion 152 to the open position against the acting force of the elastic member 153. In one embodiment, the actuating portion 154 is disposed at the lower end of the clamp portion 152, and the rotating shaft 159 is disposed at the front side of the clamp portion 152. In another embodiment, the actuating portion 154 may be disposed at the top end of the clamp portion 152, and the rotating shaft 159 may be disposed at the rear side of the clamp portion 152. When the clamping portion 152 is in the closed position, the actuating portion 154 closes the opening at the bottom end of the case 151 to prevent the seat belt 200 from slipping out of the case 151 through the opening of the case 151, and the actuating portion 154 protrudes at least partially laterally outside the case 151, making it easier for the user to pull the clamping portion 152. When the child seat 1 is subjected to an impact, the limiting member 140 supports the seat belt 200 and limits the movement of the seat belt 200. In cooperation with the arrangement of the clamping member 150, the risk of the seat belt 200 slipping out of the opening is effectively reduced.

[0033] In one embodiment, the elastic member 153 is a torsion spring, which is disposed on the pivot 159 and has two torsion spring legs (not shown) that respectively abut against the case 151 and the clamp portion 152. In other embodiments, the elastic member 153 may be a compression spring or some other elastic material.

[0034] In one embodiment, the child seat 1 may further include a protrusion 160 for further engaging with the seat belt 200. The protrusion 160 may be provided on each side of the seat main body 100. The protrusion 160 extends forward from the inner wall of the backrest frame 120 and is formed in the passage 130 to restrict a part of the seat belt 200 (for example, a shoulder belt 210 or a waist belt 220, which will be described in detail later) from moving upward relative to the seat main body 100.

[0035] The protrusions 160 are designed to limit movement of both the shoulder belt 210 and the lap belt 220 of the seat belt 200, ensuring that the child seat 1 is more securely engaged.

[0036] The operation of engaging the seat belt 200 with the child seat 1 according to the present application will be described with reference to Figs.

[0037] This application is applied to a general automobile seat belt 200. The seat belt 200 includes a shoulder belt 210, a waist belt 220, a tongue 230, and a buckle 240. The shoulder belt 210 and the waist belt 220 extend from the upper end and the lower end of the vehicle seat 2, respectively, join and are connected to the tongue 230, and at least one of the shoulder belt 210 and the waist belt 220 can be pulled out from the vehicle seat 2, and the length of the shoulder belt 210 and / or the waist belt 220 is variable. The tongue 230 is connected to the lower end of the vehicle seat 2 by a buckle 240 in the vehicle seat 2, so that the seat belt 200 has a triangular configuration. That is, the child seat 1 of the application can be applied to a general seat belt 200 having a triangular configuration. The shoulder belt 210, the lap belt 220, and the buckle 240 each have a shoulder belt engaging end 211, a lap belt engaging end 221, and a buckle engaging end 241 that are engaged with the vehicle seat 2. The shoulder belt engaging end 211 is located at the upper end of the vehicle seat 2. The lap belt engaging end 221 and the buckle engaging end 241 are located at the lower end of the vehicle seat 2, laterally spaced apart, and located on the left and right sides of the occupant, respectively. The manner in which the shoulder belt engaging end 211, the lap belt engaging end 221, and the buckle engaging end 241 are connected to the vehicle seat 2 is known in the art and can be changed according to a specific use case, so this application will omit a detailed description of these parts.

[0038] When the child seat 1 is attached to the vehicle seat 2 in the forward-facing position shown in FIG. 10, the seat belt 200 is engaged according to the following operations: The seat belt 200 is pulled out from the vehicle seat 2. The shoulder belt 210 is inserted into the gap between the limiting member 140 and the seat main body 100 through the slot 143 of the limiting member 140. The clamping portion 152 of the clamping member 150 is rotated to the open position, the shoulder belt 210 is inserted between the clamping portion 152 and the case 151, and the clamping portion 152 is released to clamp the shoulder belt 210 in the clamping member. The portion of the shoulder belt 210 that has passed through the clamping portion 152, as well as the waist belt 220 and the tongue 230, are allowed to reach the other side of the child seat 1 through the passage 130. The tongue 230 is engaged with the buckle 240. The seat belt 200 is fastened so that the waist belt 220 is positioned under the protrusions 160 on both sides to prevent the waist belt 220 from sliding up. The shoulder belt 210 may be located under the corresponding projection 160 on one side.

[0039] When the child seat 1 is installed in the vehicle seat 2 in the rearward facing position shown in Figure 11, the seat belt 200 is engaged in a similar manner to that shown in Figure 10, except that the other side limiting member 140 and clamping member 150 are used and the waist belt 220 is located within the vertical portion 131 of the passage 130 rather than below the protrusion 160, thereby allowing the seat 1 to be better tightened towards the backrest of the vehicle seat 2.

[0040] It should be understood that it is not necessary to strictly follow the above operating sequence for engaging the seat belt 200 with the limiting member 140 and the clamping member 150. When the child seat 1 is mounted on the vehicle seat 2 in a forward-facing or rearward-facing position, the seat belt 200 may be first engaged with the limiting member 140 and then engaged with the clamping member 150, or alternatively, the seat belt 200 may be first engaged with the clamping member 150 and then engaged with the limiting member 140.

[0041] It can be seen that the engagement between the seat belt 200 and the child seat 1 is the same when the child seat 1 is in a forward or rearward facing position. Furthermore, since the limiting member 140 and the clamping member 150 are provided on both sides of the child seat 1, the child seat 1 can be adapted to a left-handed setting of the seat belt 200 (shoulder belt engagement end 211 and lap belt engagement end 221 are on the left hand side of the occupant) or a right-handed setting (shoulder belt engagement end 211 and lap belt engagement end 221 are on the right hand side of the occupant).

[0042] According to the seat belt engagement method of the present application, the seat belt 200 can engage with the child seat 1 by the same engagement method when the child seat 1 is in a forward-facing position or a rear-facing position, thereby simplifying the operation and avoiding the risk of improper engagement.

[0043] Because the present application may be embodied in various forms without departing from the spirit and essence of the present application, it is to be understood that the above-described embodiments should not be limited to any of the above-described details, but should be construed in the broadest sense as defined by the claims, and therefore, all modifications that come within the scope of the claims or their equivalents should be embraced by the claims.
