[0011] In this specification, the present disclosure has been described with reference to specific embodiments, but the present disclosure should not be limited to the illustrated details. On the contrary, within the equivalent scope of the claims, various modifications can be made to these details without departing from the present disclosure.

[0012] The descriptions of directions such as "front", "rear", "upper", and "lower" mentioned here are only for easy understanding, and the present disclosure is not limited to these directions and can be adjusted according to the actual situation.

[0013] Referring to FIGS. 1 and 2, FIGS. 1 and 2 schematically show a child seat 1100 in an embodiment of the present disclosure and an anti-slip mechanism provided thereon. FIG. 1 shows the child seat 1100 provided with the anti-slip mechanism, and FIG. 2 shows a partial enlarged view of the anti-slip mechanism. The purpose of this embodiment is to provide a child seat that can reduce the forward displacement of a child when the child seat is impacted. Another purpose of this embodiment is to provide an anti-slip mechanism with a simple structure, convenient production and processing, and low cost.

[0014] The child seat 1100 includes a seat body and a seat fabric 1110 covering the seat body. Since the seat body of the child seat 1100 in FIG. 1 is covered with the seat fabric 1110, it is not shown. As shown in FIG. 1, the seat fabric 1110 of the child seat 1100 includes a hip region 1111 and a leg region 1112. The hip region 1111 is usually located on the seat fabric of the child seat 1100 and is close to the backrest. The leg region 1112 is usually located in other regions of the seat fabric of the child seat 1100 and includes a side leg region 1113 and a lower leg region 1114.

[0015] The child seat 1100 according to the present disclosure is provided with an anti-slip mechanism. In an embodiment, the anti-slip mechanism is provided on the seat fabric 1110 of the child seat 1100 and prevents the seat fabric 1110 from sliding with respect to an object in contact with the seat fabric (for example, a child sitting on the seat fabric 1110 of the child seat 1100, or the seat body of the child seat 1110 in contact with the inner surface of the seat fabric 1110, etc.).

[0016] As shown in FIG. 1, the anti-slip mechanism includes a first anti-slip portion 1130. The first anti-slip portion 1130 is provided on the outer surface of the seat fabric 1110 and is at least partially provided in the hip region 1111 in order to increase the friction with the seat fabric 1100 of the child seat 1100 sitting on the seat fabric 1110 within the child seat 1100. However, the present disclosure is not limited thereto. In other embodiments, the first anti-slip portion 1130 may be provided in the leg region 1112, for example, the side leg region 1113 and / or the lower leg region 1114, in order to increase the friction with the seat fabric 1110 of the child seat 1100 from a plurality of directions.

[0017] As shown in FIG. 2, the first anti-slip portion 1130 is sewn, adhered, or printed on the seat fabric 1110, or is provided by being fixed to the seat fabric 1100. The first anti-slip portion 1130 is made of a material having a greater friction than the seat fabric 1110. Optionally, the first anti-slip portion 1130 is a material having a greater friction, such as a silicone sheet or a rubber sheet.

[0018] Referring to FIG. 3, FIG. 3 schematically shows a child seat 1200 in another embodiment of the present disclosure. In FIG. 3, the seat fabric 1210 located at the backrest of the child seat 1200 is folded forward as shown to indicate an anti-slip mechanism on the inner surface of the seat fabric 1210.

[0019] The anti-slip mechanism of the child seat 1200 according to this embodiment is provided on the inner surface of the seat fabric 1210 (i.e., the surface facing the seat body 1220 of the child seat 120), increasing the friction between the seat fabric 1210 and the seat body 1220 of the child seat 200 and significantly reducing the possible displacement therebetween.

[0020] As shown in FIG. 3, in this embodiment, the anti-slip mechanism is provided on the inner surface of the seat fabric 1210 and includes a first anti-slip portion 1230 provided at least partially on the hip region 1211 on the seat fabric 1210 of the child seat 1100. However, the present disclosure is not limited thereto. In other embodiments of the present disclosure, the first anti-slip portion 1230 may be provided at a position corresponding to the seat body 1220 of the child seat 1200, for example, the hip region 1211 of the seat fabric 1210 of the seat body 1220. In the embodiment, the first anti-slip portion 1230 is a single member provided on the seat fabric 1210 as shown in the hatched portion of FIG. 3.

[0021] Referring to FIG. 4, FIG. 4 schematically shows a plan view of the first anti-slip portion 1230 in an embodiment of the present disclosure. As shown in FIG. 4, an embossed pattern is provided on the surface of the first anti-slip portion 1230 and is distributed almost uniformly with a certain regularity. In the embodiment, the first anti-slip portion 1230 is made of a silicone material and is printed on the inner surface of the sheet cloth 1210.

[0022] Referring to FIGS. 5 and 6, FIGS. 5 and 6 show plan views of the child seat 1200a in an embodiment of the present disclosure and the first anti-slip portion 1230a provided thereon.

[0023] In the embodiment, the ventilation holes 1231a are provided in the first anti-slip portion 1230a. Specifically, the ventilation holes 1231a are formed in the first anti-slip portion 1230a by pressing. For example, when the first anti-slip portion 1230a is made of a silicone resin material, the ventilation holes 1231a are punched out on the silicone resin layer, and after printing the silicone resin layer, a part of the silicone resin layer is removed, so that the silicone resin layer is not provided at the position where the ventilation holes 1231a are provided. Alternatively, during printing and molding, the ventilation holes 1231a are formed in some regions, so that the first anti-slip portion 1230a having the ventilation holes 1231a is directly formed on the sheet cloth 1210a.

[0024] In this embodiment, the ventilation holes 1231a are provided only in the silicone printing area to enhance the permeability of the sheet cloth 1210a after silicone printing. The size of the silica gel printing area is between 230 mm * 150 mm and 250 mm * 170 mm, preferably 243 mm * 165 mm. The ventilation holes 1231a are uniformly distributed in the silica gel printing area. For example, as shown in FIG. 6, the interval in the vertical or horizontal direction is in the range of 10 mm to 20 mm, preferably 15 mm. Also, the diameter of the ventilation holes 1231a is in the range of 5 mm to 15 mm, preferably 10 mm.

[0025] Referring to FIG. 7, FIG. 7 schematically shows the child seat 1200b in an embodiment of the present disclosure.

[0026] In an embodiment, as shown in FIG. 7, the first anti-slip portion 1230b is a plurality of members uniformly distributed on the seat fabric 1210b of the child seat 1200b, for example, as shown in FIG. 7, a plurality of strip members uniformly distributed along the transverse direction D1. The first anti-slip portion 1230b composed of a plurality of uniformly distributed members is provided on the inner surface of the seat fabric 1210b by sewing, pasting, printing or other fixing, and is at least partially located in the hip region 1211b of the child seat 1200b. The members of the first anti-slip portion 1230b are made of a material with greater friction than the seat fabric 1210b, and optionally, are made of a material with greater friction such as a silicone sheet or a rubber sheet.

[0027] Also, the configuration of the first anti-slip portion of the present disclosure is not limited to this. In other embodiments, the first anti-slip portion is a circular, elliptical or other overall structure, or a circular array, rectangular array or other discrete structure uniformly distributed in the transverse and longitudinal directions.

[0028] Referring to FIG. 8, FIG. 8 schematically shows a child seat 1300 and an anti-slip mechanism provided thereon according to an embodiment of the present disclosure.

[0029] The anti-slip mechanism in this embodiment includes a second anti-slip portion 1340 for positioning the seat fabric 1310 on the seat body 1320 of the child seat 1300 covered by the seat fabric 1310. In the embodiment, the second anti-slip portion 1340 is provided at least in the hip region 1311 of the seat fabric 1310 of the child seat 1300. As shown in FIG. 8, the second anti-slip portion 1340 includes one or more connecting elements 1341 provided on the seat fabric 1310 and one or more fitting elements 1342 provided at corresponding positions on the seat body 1320 of the child seat 1300. Specifically, one or more connecting elements 1341 are provided on the hip region 1311 of the seat fabric 1310, and one or more fitting elements 1342 are provided in a region corresponding to the hip region 13111 of the seat body 1320. The connecting element 1341 is detachably connected to the fitting element 1342 so as to re-fix the seat fabric 1310 and the seat body 1320 after the seat fabric 1310 is attached to the seat body 1320 of the child seat 1300, increase the fastening force between the seat fabric 1310 and the seat body 1320, prevent the seat fabric 1310 from sliding forward with respect to the seat body 1320, and prevent the child sitting on it from sliding forward. In the embodiment, one of the connecting element 1341 and the fitting element 1342 is a clamp opening or a clamp slot or a cloth loop, and the other of the connecting element 1341 and the fitting element 1342 is a hook or a fixed buckle.

[0030] Optionally, one or more connection elements 1341 are provided at the edge of the seat fabric 1310, or at the edge of the hip region 1311 of the seat fabric 1310, and one or more fitting elements 1342 are provided at each position of the seat body 1320 of the child seat 1300 to firmly position the seat fabric 1310 by the seat body 1320. Optionally, the connection element 1341 is disposed at the corner of the entire structure of the seat fabric 1310. Also, the connection element 1341 and the fitting element 1342 are disposed centrally or symmetrically with respect to the longitudinal central axis of the child seat 1100. In other embodiments, the connection element 1341 and the fitting element 1342 are provided in the leg region such as the seat fabric.

[0031] Referring to FIG. 9, FIG. 9 schematically shows a child seat 1400 according to an embodiment of the present disclosure and an anti-slip mechanism provided thereon.

[0032] As shown in FIG. 9, the anti-slip mechanism of the child seat 1400 of this embodiment includes a first anti-slip portion 1430 and a second anti-slip portion 1440. The first anti-slip portion 1430 is provided on the inner surface of the seat fabric 1410, and although not repeated here, it can be replaced with the configuration in any of the embodiments shown in FIGS. 3 to 7. The second anti-slip portion 1440 is configured to position the seat fabric 1410 on the seat body 1420 of the child seat 1400, and includes one or more connection elements 1441 disposed on the seat fabric 1410 and one or more fitting elements 1442 disposed at corresponding positions on the seat body 1420 of the child seat 1400. These connection elements 1441 and fitting elements 1442 have the same structure as the embodiment shown in FIG. 8, and are not repeated here. Alternatively, both the first anti-slip portion 1430 and the second anti-slip portion 1440 are at least provided in the hip region 1411 of the seat fabric 1410.

[0033] By causing the first anti-slip portion 1430 and the second anti-slip portion 1440 to cooperate, it is possible to simultaneously form friction and connection between the seat fabric 1410 and the seat body 1420, and at the same time increase the friction and fastening force between the two. Furthermore, when the vehicle (for example, the automobile described in this embodiment) receives an impact, it is possible to reduce the possible forward displacement of the seat fabric 1410 relative to the seat body 1420, reduce the forward displacement of the child sitting on the child seat 1400, and reduce the pressure of the seat belt on the child's abdomen.

[0034] It should be noted that the above embodiments of the present disclosure can also be used in combination. For example, in the embodiment shown in FIG. 1, the first anti-slip portion located on the outer surface of the seat fabric and the first and / or second anti-slip portions located on the inner surface of the seat fabric in any of the embodiments shown in FIGS. 3 to 9 can be provided simultaneously. By simultaneously providing the first anti-slip portion on the outer surface of the seat fabric and the first anti-slip portion / the second anti-slip portion on the inner surface of the seat fabric, the frictional force and fastening force between the child and the seat fabric and between the seat fabric and the seat body are increased, thereby significantly reducing the forward displacement of the seat fabric and the child, and significantly reducing the pressure of the seat belt on the child's abdomen.

[0035] As described above, by providing the anti-slip mechanism according to the present disclosure, the safety of the child seat can be effectively improved, and the impact of a vehicle collision on a child sitting on the child seat can be significantly reduced.

[0036] For example, as shown below, Tables 1 and 2 respectively show the data results of impact tests conducted without an anti-slip mechanism and impact tests using the anti-slip mechanism of the examples of the present disclosure. In Tables 1 and 2, Q3, Q6, and Q10 are dummies having different weights and heights, for example, indicating that the height and weight of Q3 are less than those of Q10.

[0037]

Table 1

[0038] As shown in Table 1, in the test of the acceleration of the head during a vehicle collision (also called the head resultant acceleration), when the child seat does not use a slip prevention mechanism, the head resultant acceleration received by Q3 or Q6 exceeds the safety range (that is, greater than 80), and the head resultant acceleration received by Q10 is very likely to exceed the safety range. Also, in the abdominal pressure test of the seat belt on the dummy during a vehicle collision, pressures exceeding the safety range (for example, 1.0 or 1.2) are applied to different dummies to different extents.

[0039] [Table 2]

[0040] As shown in Table 2, the slip prevention mechanism of the embodiment of the present disclosure is to ensure that the accelerations of the head part and the abdominal pressure are within the safety range when the vehicle is impacted.

[0041] Therefore, by comparing the test data shown in Table 1 and Table 2, it can be seen that providing the slip prevention mechanism according to the embodiment of the present disclosure can not only effectively and significantly reduce the pressure (that is, abdominal pressure) applied by the seat belt to the child's abdomen during a vehicle collision, but also significantly reduce the head acceleration received by the child, thereby further improving the driving safety.

[0042] Therefore, the slip prevention mechanism of this embodiment provides a slip prevention mechanism between the outer surface of the seat fabric and / or between the inner surface of the seat fabric and the seat body, increases the friction and fastening force between the child, the seat fabric, and the seat body, and significantly reduces the forward displacement of the child relative to the seat body when impacted. Thereby, the pressure of the seat belt on the child's abdomen is significantly reduced, and the safety of the child sitting on the child seat is improved. At the same time, the slip prevention mechanism of this embodiment has the beneficial technical effect that the structure is simple, the production and processing are convenient, there is no need to modify the mechanism of the seat body, so there is no need to modify the mold, and the production cost is low.

[0043] Figure 10 schematically shows a child seat 2100 in an embodiment of the present disclosure, and the child seat 1100 applies a seat belt protection device 2001 in an embodiment of the present disclosure.

[0044] The child seat 2100 includes a seat body 2002 and a base (not shown in FIG. 10) for attaching the seat body 2002. The seat body 2002 includes a seat portion 2002a and a backrest portion 2002b. The side wings on both sides of the seat portion 2002a can be folded upward with respect to the middle portion of the seat portion 2002b, and the side wings on both sides of the backrest portion 2002b can also be folded forward toward the front of the seat with respect to the middle portion of the backrest portion 2002a, which facilitates the seating of a child in the seat body 2002. Depending on different positions on the rear seat of a vehicle (e.g., an automobile as described in this embodiment) of the child seat 2100, different seat belts 2008 (i.e., seat belts attached to a vehicle such as an automobile, in other words, automobile seat belts) are used to restrain the child. For example, in FIG. 10, the child seat 2100 is fixed to the left rear seat of the vehicle, and in the use state, the left seat belt 2008 is joined to a buckle on the vehicle seat via a belt buckle 2083. The seat belt 2008 is divided into a shoulder belt portion 2081 and a waist belt portion 2082 by the belt buckle 2083. The shoulder belt portion 2081 extends diagonally across the left shoulder and right waist of the child, and the waist belt portion 2082 extends across the waist of the child.

[0045] Referring to FIGS. 10 and 12, the seat belt protection device 2001 is attached to the seat body 2002 of the child seat 2100 and includes a first engaging element 2011, a second engaging element 2012, and a fabric tape 2013.

[0046] Each of the first engaging element 2011 and the second engaging element 2012 has a structure suitable for detachably connecting to the shoulder belt portion 2081. In some embodiments, for example, the first engaging element 2011 and the second engaging element 2012 can use the hook 2003 shown in FIG. 11. The hook 2003 has a U-shaped cross section and is hung upside down on the shoulder belt portion 2081 so as to catch on the shoulder belt portion 2082. The hook 2003 and the shoulder belt portion 2081 are very easy to engage with and disengage from each other. In some other embodiments, various embodiments of the first engaging element 2011 and the second engaging element 2012 can also be provided as long as they are detachably joined to the shoulder belt portion 2081. For example, in some embodiments, each of the first engaging element 2011 and the second engaging element 2012 is an annular sleeve that passes through the shoulder belt portion 2081, and the through hole in the annular sleeve is an annular sleeve that can be opened and closed. For example, the annular sleeve is made of metal, plastic, or cloth. When the annular sleeve is formed of cloth, the annular sleeve is closed by, for example, buttons, magnetic buckles, three-rod buckles, fasteners, etc. In FIG. 10, the structures of the first engaging element 2011 and the second engaging element 2012 are the same, and it is understood that in some embodiments, the first engaging element 2011 and the first engaging element 2012 may be different from each other.

[0047] The first engaging element 2011 and the second engaging element 2012 are connected by a fabric tape 2013. By arranging the fabric tape 2013 around the sheet body 2002, the first engaging element 2011 protrudes from the first side 2021 (the right side of the sheet body 2002) of the sheet body 2002, and the second engaging element 2012 protrudes from the second side 2022 (the left side of the sheet body 2002) of the sheet body 2002. In some embodiments, inside the sheet body 2002, a guide slot or guide hole structure for guiding the orientation of the fabric tape 2013 is provided. On the first side 2021 of the sheet body 2002 (for example, the side wing of the backrest part 2002b on the first side or the side wing of the seat part 2002a), a first opening 2210 is provided. On the second side 2022 of the sheet body 2002 (for example, the side wing of the backrest part 2002b on the second side or the side wing of the seat part 2002a), a second opening 2220 is provided. The first end 2131 of the fabric tape 2013 protrudes from the first opening 2210 and is connected to the first engaging element 2011, and the second end 2132 of the fabric tape 2013 protrudes from the second opening 2220 and is connected to the second engaging element 2012. By pulling the first engaging element 2011 or the second engaging element 2012, the fabric tape 2013 slides left and right relative to the sheet body 2002.

[0048] In other embodiments, instead of protruding from the inside of the sheet body 2002, both ends of the fabric tape 2013 can protrude directly from the outer periphery of the sheet body 200. For example, in some embodiments, some perforations or hooks for guiding the orientation of the fabric tape 2013 can be arranged on the outer peripheral surface of the backrest part 2002b. The fabric tape 2013 passes through the perforations or hooks, and both sides of the fabric tape 2013 are separated from the backrest part 2002a on both sides of the backrest part 2002b. The first end of the fabric tape 2013 extends from the periphery of the first side 2021 of the sheet body 2002 and is connected to the first engaging element 2011, and the second end of the fabric tape 2013 extends from the periphery of the second side 2022 of the sheet body 2022 and is connected to the second engaging element 2012.

[0049] In some other embodiments, both ends of the fabric tape 2013 protrude from both sides of the seat portion 2002a of the seat body 2002, rather than from both sides of the backrest portion 2002b of the seat body 200. For example, in some embodiments, a guide slot is provided in the seat portion 2002a, and both ends of the fabric tape 2013 are guided to pass through two openings formed on both sides of the seat portion 2002a respectively. After protruding from both sides of the seat portion 2002b, they are respectively connected to the first engaging element 2011 and the second engaging element 2012.

[0050] Unless otherwise specified and limited, the directional terms such as "front", "rear", "left" and "right" in this embodiment correspond to the directions of "front", "rear", "left" and "right" as described when a child is sitting on the child seat 2100. It should be noted that arrows L and R are shown to schematically indicate the directions of "left" and "right" respectively. These directional terms are used only to make the description of the embodiments of the present disclosure clearer and are not used to properly limit the protection scope of the present disclosure.

[0051] Referring again to FIG. 10, when the fabric tape 2013 is pulled on the second side (the left side of the child seat) 2022 of the seat body 2002, the first engaging element 2011 is drawn into the seat body 2002, and the second engaging element 2012 is pulled on the seat body 2022. The first engaging element 2011 abuts against the wall of the first opening 2210 to limit the length of the fabric tape 2013 pulled by the second engaging element 2012. At this time, the second engaging element 2012 is drawn out of the seat body 2002 and then detachably connected to the shoulder belt portion 2081, applying a downward pulling force including obliquely downward to the shoulder belt portion 2082. The position where the second engaging element 2012 engages with the shoulder belt portion 2081 is close to the middle portion of the shoulder belt portion 2082. When the vehicle collides, the fabric tape 2013 pulls the shoulder belt portion 2081 through the second engaging element 2012, applying a downward pulling force to the shoulder belt portion 2082, bringing the shoulder belt portion 2083 closer to the waist belt portion 2082, effectively preventing the upper part of the shoulder belt portion 2084 from sliding upward, preventing the shoulder belt portion 2080 from damaging the child's neck and face, and enhancing the safety of the child when traveling. When it is necessary to remove the child seat 2100 from the vehicle seat, the connection relationship between the second engaging element 2012 and the shoulder belt portion 2081 is released, and the seat belt protection device 2001 separated from the child seat together with the child seat 210, and the seat belt 2008 can continue to be used to fix the adult.

[0052] Correspondingly, when the child seat 2100 is attached to the right seat of the vehicle, the shoulder belt portion 2081 of the right seat belt 2008 extends diagonally across the child's right shoulder and left waist. The fabric tape 2013 is pulled on the first side (i.e., the right side of the child seat) 2021 of the seat body 2002, the second engaging element 2012 is retracted with respect to the seat body 2002, and the first engaging element 2011 is pulled with respect to the seat body 200. The second engaging element 2012 abuts against the wall of the second opening 2220 to limit the length of the fabric tape 2013 pulled by the first engaging element 2011. At the same time, the first engaging element 2011 is pulled out with respect to the seat body 2002 and then detachably connected to the shoulder belt portion 2081, applying a downward pulling force including diagonally downward to the shoulder belt portion 2082, causing the shoulder belt portion 2083 to slide upward and avoiding damaging the child.

[0053] In some embodiments, the first opening 2210 has a structure for accommodating the first engaging element 2011, and the retracted first engaging elements are respectively accommodated in the first opening 2210. Further, the second opening 2220 is provided with a structure for accommodating the second engaging element 2012, and since the retracted second engaging element 2012 is accommodated in the second opening 3220, it is advantageous in appearance and can prevent the child from colliding with the suspended first engaging element 2011 and second engaging element 2012.

[0054] As described above, when the child seat 2100 with the seat belt protection device 2001 disposed therein restricts the movement of a child using the seat belt 2008, depending on the position of the child seat 210 on the rear vehicle seat, the fabric tape 2013 is pulled left or right, one of the first engagement element 2011 and the second engagement element 2012 is drawn in and housed, and the other engages with the shoulder belt portion 2081 to apply a downward pulling force to the shoulder belt portion 2082, preventing the shoulder belt portion 2083 from sliding upward and damaging the child. When the child seat 2100 is attached to different sides of the rear vehicle seat, since it is not necessary to remove the seat belt protection device 2001, the seat belt protection device 2001 remains attached to the child seat 210 and will not be lost. Also, when one of the first engagement element 2011 and the second engagement element 2012 engages with the shoulder belt portion 2081, the other is drawn in and cannot engage with the shoulder belt portion 2080, thereby avoiding the problem that an effective pull cannot be formed on the shoulder belt portion 2082 due to misuse of the engagement element by the user, and improving the safety and comfort of the child seat.

[0055] Referring to FIGS. 10, 12-16, in some embodiments, the first limiting structure 2004 is disposed on the fabric tape 2013, and the first limiting structure 104 is disposed between the first engagement element 2011 and the second engagement element 2012. The seat body 2002 is provided with a second limiting structure 2005, and the second limiting structure 2005 cooperates with the first limiting structure 2004 to limit the pulling stroke of the fabric tape 2013 for limiting the length of the fabric tape 2013 pulled by the first engagement element 2011 and the second engagement element 2012. It is understood that the first limiting structure 2004 and the second limiting structure 2005 are provided so that the stroke of the fabric tape 2013 is not limited by the contact between the first engagement element 2011 and the wall of the first opening 2210 and the contact between the second engagement element 2012 and the wall of the second opening 2220.

[0056] Referring to FIGS. 12, 14 to 16, a configuration example of a first limiting structure 2004 and a second limiting structure 2005 is shown. For convenience of explanation, the frame structure of the seat body 2002 is shown in FIGS. 14 and 16, and the seat fabric and the filling material in the seat body 2002 are not shown. The second limiting structure 2005 includes a first shielding surface 2510 and a second shielding surface 2520 that are disposed opposite to each other. For example, the first shielding surface 2510 is formed on the longitudinal beam 2051 of the frame structure of the seat body 2002, the second shielding surface 2520 is formed on the longitudinal beam 2052 of the frame structure of the seat body 2002, and the longitudinal beam 2051 and the longitudinal beam 2052 are disposed at intervals. A first through hole 2511 is provided in the first shielding surface 2510, and a second through hole 2521 is provided in the second shielding surface 2520. The first limiting structure 2004 includes a limiting block 2041 fixed to the fabric tape 2013. For example, the limiting block 2041 is fixed to the fabric tape 2013 via a fastener (not shown). The fastener is a rivet, that is, the limiting block 2041 and the fabric tape 2013 are fixed by the rivet. The first end 2131 of the fabric tape 2013 extends forward through the first through hole 2511, the second end 2132 of the fabric tape 2013 extends forward through the second through hole 2521, and the limiting block 2041 is located between the first shielding surface 2510 and the second shielding surface 2520. The volume of the limiting block 2041, or more specifically, the cross-sectional area of the limiting block 2040 in a direction perpendicular to the extending direction of the fabric tape 2013 is substantially larger than the opening area of each of the first through hole 2511 and the second through hole 2521, so that the limiting block 2041 cannot enter the guide slot in the seat body 2002 through the first through hole 2511 or the second through hole 2520, and can only move between the first shielding surface 2510 and the second shielding surface 2520. Referring to FIG. 15, when the first engaging element 2011 retracts and the second engaging element 2012 is pulled out to engage with the shoulder belt portion 2081, the limiting block 2041 abuts against the second shielding surface 2520 to limit the length of the fabric tape 2013 pulled in by the second engaging element 2012.Referring to FIG. 16, when the second engaging element 2012 is retracted and the first engaging element 2011 is pulled out to engage with the shoulder belt portion 2081, the limiting block 2041 abuts against the first shielding surface 2510 to limit the length of the fabric tape 2013 drawn in by the first engaging element 201. The adjacent between the limiting block 2041 and the first shielding surface 2510 or the second shielding surface 2520 can withstand a greater pulling force compared to the adjacent between the first engaging element 2011 and the first opening 2210, and the adjacent between the second engaging element 2012 and the second opening 2220.

[0057] In some embodiments, the first receiving groove is provided on the back surface of the first side 2021 of the seat body 2002, and the second receiving groove is provided on the back surface of the second side 2022 of the seat body 2002. The first receiving groove on the back surface of the first side 2021 is arranged to receive the first engaging element 2011, and the second receiving groove on the back surface of the second side 2022 is configured to receive the second engaging element 2012. For example, when the child seat 2100 is in a non - use state, neither the first engaging element 2011 nor the second engaging element 2012 needs to engage with the shoulder belt portion 2081. At this time, the fabric tape 2013 is returned to an appropriate position, the first engaging element 2011 is received in the first receiving groove, and the second engaging element 2012 is received in the second receiving groove. Alternatively, when the child seat 2100 is in a non - use state, the first engaging element 2011 is received in the first opening 2210, the second engaging element 2012 is received in the second receiving groove, or the second engaging element 2012 is received in the second opening 2220, and the first engaging element 2011 is received in the first receiving groove.

[0058] FIG. 13 shows another configuration example of the first restriction structure 2004 and the second restriction structure 2005. The auxiliary belt 2006 is attached in the middle of the fabric tape 2013, and the first end 2061 and the second end 2062 of the auxiliary belt 2006 are connected to the fabric tape 2013 by, for example, sewing. The first restriction structure 2004 includes a restriction ring 2042 surrounded by the fabric tape 2013 and the auxiliary belt 2006. The second restriction structure 2005 includes, for example, a restriction column 2053 in which a restriction column 2055 is arranged in a vertical direction perpendicular to the extending direction of the fabric tape 2013. The lower end of the restriction column 2053 is connected to the frame structure of the seat body 2002 via a link, or the lower end of the restriction column 1053 is directly fixed to the frame structure of the seat body 200. The upper end of the restriction column 2053 is folded toward the frame structure of the seat body 2002, and a gap is formed between the upper end of the restriction column 2054 and the seat body 2002. The fabric tape 2013 passes through the gap so that the restriction column 2053 passes through the restriction ring 2042. In this way, when the fabric tape 2013 is pulled to the left or right, both ends of the restriction ring 2042, that is, the first end 2061 and the second end 2062 of the auxiliary belt 2006, cooperate with the restriction column 2053 that is a restriction end to restrict the stroke of the fabric tape 2053.

[0059] Referring to FIGS. 17 and 18, in some embodiments, the first engagement element 2011 and / or the second engagement element 2012 includes the first sheath 2007 and the hook 2003 described above. At least a part of the hook 2003 is enclosed in the first sheath 2007, and the first sheath 2007 has a first passage (not shown) for the shoulder belt portion 2081 to pass through. A part of the shoulder belt portion 2081 passing through the first sheath 2007 is hooked on the hook 2003. The first sheath 2007 can provide a better anti-slip effect to avoid the hook 2003 from sliding along the shoulder belt portion 2081 and ensure a reliable traction of the seat belt protection device 2001 on the shoulder belt portion 2082. The first sheath 2007 can also buffer the collision between the hook 2003 and the child and improve the comfort of the child during driving.

[0060] As shown in FIGS. 17 and 18, in some embodiments, the first sheath 2007 includes a first half portion 2071 and a second half portion 2072 that face each other, and side portions 2711 of the first half portion 2071 and side portions 2721 of the second half portion 2072 that face each other are detachably connected. When the side portions 2711 of the first half portion 2071 and the side portions 2721 of the second half 2072 that face each other are connected, a passage is defined in the shoulder belt portion 2081 so that the shoulder belt portion 2082 passes through, corresponding to the closed state of the first sheath 2007. When the side portion 2711 of the first half portion 2071 of the first sheath 2007 is separated from the side portion 2721 of the second half portion 2072, the first sheath 2007 is removed from the shoulder belt portion 2081 corresponding to the open state of the first sheath 2007. There are many detachable connection methods between the side portion 2711 of the first half portion 2071 and the side portion 2721 of the second half portion 2072, such as snap connection, fiber-reinforced nylon fastener connection, etc. Note that the hooks 2003 of the first engaging element 2011 and the hooks 2003 of the second engaging element 2012 can share the first sheath 2007 in order to reduce costs.

[0061] Referring to FIG. 18, in some embodiments, the first sheath 2007 includes a positioning structure 2073, and the hook 2003 is detachably connected to the positioning structure 2073. Providing the positioning structure 2073 is advantageous for fixing the relative position between the hook 2003 and the first sheath 2007 and preventing the hook 2003 from detaching from the first sheath 2007 when the seat belt protection device 2001 pulls the shoulder belt portion 2081. The positioning structure 2073 includes, for example, a strip 2073a. The first end 2731 and the second end 2732 of the strip 2073a are connected to the inner surface of the first sheath 2007 by sewing, for example, and the middle portion of the strip 2073a is hooked by the hook 2003.

[0062] In some embodiments, at least one of the first engaging element 2011 and the second engaging element 2012 is connected to the fabric tape 2013 at an adjustable position, thereby adjusting the height of the fabric tape 2013 between the first engaging elements 2012012 according to the child's height. There are many ways to adjust the length of the fabric tape 2013 between the first engaging element 2011 and the second engaging element 2012. For example, in some embodiments, the fabric tape 2013 includes an elastic belt.

[0063] Referring to FIG. 19, when the hook 2003 is used for the first engaging element 2011 and the second engaging element 2013, the hook 2003 is connected to the fabric tape 2013 via its connecting portion 2031. The connecting portion 2031 is, for example, a buckle of three rods, a buckle of four rods, etc., and is an anti-slip structure at a position where it engages with the fabric tape 2013 to prevent unwanted slipping between the hook 2003 and the fabric tape 2013 when the seat belt protection device 2001 is used. A plurality of indication areas 2136 corresponding to different height ranges of the child are provided on the fabric tape 2013, and the user can connect the corresponding indication area 213 to the connecting portion 2031 according to the child's height.

[0064] For example, in some embodiments, three indication regions 2136 are provided at each of the first end 2131 and the second end 2132 of the fabric tape 2013 and are displayed in different colors. For example, "white" represents a height from 105 cm to 125 cm, "orange" represents the position of the fabric tape corresponding to a height from 125 cm to 135 cm, and "blue" represents the position of the fabric tape corresponding to a height of 135 cm or more. Before the child sits on the child seat, the corresponding position of the fabric tape 2013 is adjusted to the position where it engages with the connecting portion 2031 according to the height of the child. The color of each indication region 2136 is realized by a weaving method that changes the color of the weft yarn, and wear and color fading can be avoided. The color of each indication region 2136 can also be realized by printing, which is easily realizable and has a low cost. The display method of each indication region 2136 is not limited to the above example. In some embodiments, each indication region 213 can adopt a color lamp or other appropriate methods.

[0065] In some embodiments, for example, only one of the first engaging element 2011 and the second engaging element 2012 is connected to the fabric tape 2013 at an adjustable position, and it is understood that the above indication region 2136 is provided only at one end of the fabric tape 2013.

[0066] Referring to FIG. 19 again, in some embodiments, a prompt region 2036 is provided on the hook 2003, and the prompt region 2036 can show, for example, the child's height range corresponding to the color of the indication region 2136 by a combination of patterns and characters. These patterns and characters for explanation are pasted on the prompt region 2036 or printed on the prompt region 2036 using a tape.

[0067] Referring to FIGS. 20 and 21, in some embodiments, at least one of the first engagement element 2011 and the second engagement element 2012 is the second sheath 2009, and the second sheath 2009 has a second passage for the shoulder belt portion 2081 to pass through. The second sheath 2009 can provide a better anti-slip effect and cannot slide easily along the shoulder belt portion 2081, so it can ensure the reliable traction of the seat belt protection device 2001 on the shoulder belt portion 2082. The second sheath 2009 is in contact with the child, which also helps to enhance the comfort when the child rides.

[0068] In some embodiments, the second sheath 2009 includes a third half portion 2091 and a second half portion 2092 connected to each other, and the side portion 2911 of the third half portion and the side portion 2921 of the second half portion 2092 are detachably connected to face each other. When the side portion 2911 of the third half portion 2091 and the side portion 2921 of the fourth half portion 2092 are connected to face each other, a second passage covered on the shoulder belt portion 2081 corresponding to the closed state of the second sheath 2009 is defined. When the side portion 2911 of the third half portion 2091 is separated from the side portion 2921 of the fourth half portion 2092, the second sheath 2009 is removed from the shoulder belt portion 2081 corresponding to the open state of the second sheath 2009. There are many detachable connection methods between the side portion 2911 of the third half portion 2091 and the side portion 2921 of the fourth half portion 2092, such as fastener connection, snap connection, and strong nylon snap connection.

[0069] Referring to FIG. 22, in some embodiments, the second sheath 2009 is detachably connected to the fabric tape 2013. In this way, the first engagement element 2011 and the second engagement element 2012 are used as the same second sheath 2009 to save costs. For example, connection rings 2130 are provided at both ends of the fabric tape 2013, and an openable connection sleeve 2093 is provided on the second sheath 2009. Depending on the attachment position of the child seat 2100, the first sheath 2009 is selectively connected to the connection ring 2130 at one end of the fabric tape 2013. The detachable connection method between the second sheath 2009 and the fabric tape 2013 is not limited to the above example.

[0070] FIGS. 23 to 26 schematically show a child seat 2100 in another embodiment of the present disclosure, and the child seat 1100 applies a seat belt protection device 2001 in another embodiment of the present disclosure. In the case of no collision, the structure of the seat body 2002 of the child seat 2100 can refer to the above description and will not be repeated here.

[0071] Referring to FIGS. 23 and 24, the seat belt protection device 2001 includes a third sheath 2010 and a first fabric tape 2010a. The third sheath 2010 has a third passage for the shoulder belt portion 2081 to pass through, and the third sheath 2010 is connected to the first fabric tape 2010a. Depending on the different installation positions of the child seat 2100 in the rear seat of the vehicle, the first fabric tape 2010a is selectively connected to the first side portion 2021 (for example, the side wing of the backrest portion 2002b on the first side portion or the side wing of the seat portion 2002a on the first side portion) or the second side portion 2022 (for example, the side wing of the backrest portion 2002b on the first side portion or the side wing of the seat portion 2002a on the first side portion). Since the third sheath 2010 is detachably connected to the shoulder belt portion 2081 of the corresponding seat belt 2008, the third sheath 2010 can provide a better anti-slip effect and is not easy to slide along the shoulder belt portion 2081. In this way, the first fabric tape 2010a applies a downward pulling force to the shoulder belt portion 2081 through the third sheath 2010, so that the shoulder belt portion 2081 approaches the waist belt portion 2082, and it can effectively prevent the upper part of the shoulder belt portion 2081 from sliding upward, avoid the shoulder belt portion 2081 moving upward and hurting the child, and improve the safety of the child when riding. In addition, the contact between the third sheath 2010 and the child also contributes to improving the comfort of the child when riding.

[0072] In FIG. 23, the child seat 2100 is installed in the left rear seat of the vehicle, and the left seat belt 2008 extends diagonally across the child in the child seat 2100. At this time, the first fabric tape 2010a is detachably connected to the side wing of the second side portion 2022 of the seat body 2002, and more specifically, is detachably connected to the side wing of the backrest portion 2002b of the second side portion. In other embodiments, it is detachably connected to the side wing of the seat portion 2002a on the second side. The third sheath 2010 is detachably connected to the shoulder belt portion 2081 of the seat belt 2008. In FIG. 24, the child seat 2100 is installed in the right rear seat of the vehicle, and the right seat belt 2008 extends diagonally across the child in the child seat 2100. At this time, the first fabric tape 2010a is detachably connected to the side wing of the first side portion 2021 of the seat body 2002, and the third sheath 2010 is detachably connected to the shoulder belt portion 2081 of the seat belt 2008. In the child seat 2100 of this embodiment, since the two side wings (the side wing of the first side 2021 and the side wing of the second side 2022) of the seat body 2002 share the same first fabric tape 2010a and the third sheath 2010, it can be understood that cost reduction is easy.

[0073] Figures 23 to 25 show exemplary structures of the detachable connection between the first fabric tape 2010a and the two side wings of the seat body 2002. As shown in the figures, a connection structure 2020 is provided on each of the side wings on the first side 2021 and the second side 2022 of the seat body 2002. The connection structure 2020 is, for example, a metal ring buckle sewn to the seat fabric of the seat body 2002. However, the present disclosure is not limited thereto. In some embodiments, the connection structure 2020 is disposed on only one of the side wings on the first side 2021 and the second side 2022 of the seat body 2002, for example, only on the side wing on the first side 2021. As shown in Figure 25, for example, the first end 2101 of the first fabric tape 2010a is stitched to the third sheath 2010, and the second end 2102 of the first fabric tape 2010 / a is provided with a snap button structure 2105, a fiber-reinforced nylon snap structure, or other corresponding connection structures. When the second end 2102 of the first fabric tape 2010a is connected by the locking structure 2105 or other structures, the second end 2102 of the first fabric tape 2010a forms a sleeve passing through the metal ring so that the first fabric tape 010a is detachably connected to the connection structure 2020 of the side wing on the first side 2021 or the second side 2022 of the seat body 2002. The method of detachable connection between the first fabric tape 2010a and the two side wings of the seat body 2002 is not limited to the above example.

[0074] Referring to FIG. 26, in some embodiments, the third sheath 2010 includes a fifth half portion 2103 and a sixth half portion 2104 that are connected to each other, and side portions 2103a of the fifth half portion 2103 and side portions 2104a of the sixth half portion 2104 that face each other are detachably connected. When the side portion 2103a of the fifth half portion 2103 and the side portion 2104a of the sixth half portion 2104 face each other, a third passage sleeved on the shoulder belt portion 2081 for the shoulder belt portion 2081 to pass through is defined corresponding to the closed state of the third sheath 2010. When the side portion 2103a of the fifth half portion 2103 is separated from the side portion 2104a of the sixth half portion 2104, the third sheath 2010 is removed from the shoulder belt portion 2081 corresponding to the open state of the third sheath 2010. There are many methods for the detachable connection between the side portion 2103a of the fifth half portion 2103 and the side portion 2104a of the sixth half portion 2104, such as fastener connection, snap button connection, Velcro (registered trademark) connection, etc.

[0075] FIG. 27 schematically shows a child seat 2100 in yet another embodiment of the present disclosure, and the child seat 2100 is applied together with a seat belt protection device 2001 in yet another embodiment of the present disclosure. If there is no contradiction, the structure of the seat body 2002 of the child seat 2100 can refer to the above description and will not be repeated here.

[0076] Referring to FIG. 27, the seat belt protection device 2001 includes a first fabric tape 2010a, a second fabric tape 2010b, and a third sheath 2010. The first fabric tape 2010a is connected to a first side portion 2021 of the seat body 2002 (for example, a side wing of the first side portion of the backrest portion 2002b or a side wing of the first side portion of the seat portion 2002a), and the first fabric tape 2010a is sewn to the seat fabric of the seat body 2002, for example. The second fabric tape 2010b is connected to a second side portion 2022 of the seat body 2002 (for example, a side wing of the second side portion of the backrest portion 2002b or a side wing of the second side portion of the seat portion 2002a), and the second fabric tape 2010b is sewn to the seat fabric of the seat body 2002, for example. Depending on different installation positions of the child seat 2100 in the rear seat of the vehicle, the third sheath 2010 is selectively detachably connected to the first fabric tape 2010a or the second fabric tape 2010b, applying a downward pulling force to the shoulder belt portion 2081 of the corresponding seat belt 2008, and preventing the shoulder belt portion 2081 from moving upward and hurting the child.

[0077] In FIG. 27, the third sheath 2010 is separated from the first fabric tape 2010a and detachably connected to the second fabric tape 2010b. At this time, the child seat 2100 is installed in the left rear seat of the vehicle, and the second fabric tape 2010b pulls the shoulder belt portion 2081 of the left seat belt 2008 downward and leftward via the third sheath 2010. It can be understood that when the child seat 2100 is installed in the right rear seat of the vehicle, the third sheath 2010 is separated from the second fabric tape 2010b and the third sheath 2010 is detachably connected to the first fabric tape 2010a. At this time, the first fabric tape 2010a pulls the shoulder belt portion 2081 of the right seat belt 2008 downward and rightward via the third sheath 2010 (see FIG. 24). In this embodiment, since the first fabric tape 2010a and the second fabric tape 2010b share the same third sheath 2010, the cost can be reduced.

[0078] Regarding the structure of the third sheath 2010 in the seat belt protection device 2001 shown in FIG. 27, and the detachable connection structure between the third sheath 2010 and the first fabric tape 2010a and the second fabric tape 2010b, refer to the structure of the second sheath 2009 shown in FIGS. 20 to 22 and the detachable connection structure between the second sheath 2009 and the fabric tape 2013, which will not be repeated here.

[0079] When the seat belt protection device provided by the embodiment of the present disclosure is applied to a child seat, depending on the position where the child seat is installed on the rear seat of the vehicle, the fabric tape is pulled left and right, so that one of the first engaging element and the second engaging element is accommodated, and the other is engaged with the shoulder belt of the vehicle seat belt, and a downward pulling force is applied to the shoulder belt portion to prevent the shoulder belt portion from sliding upward and causing injury to the child. When the child seat is installed on different sides of the rear seat of the child, since it is not necessary to remove the seat belt protection device, the seat belt protection device can continue to be installed on the child seat and will not be lost.

[0080] The child seat 3001 in the embodiment of the present disclosure will be generally described with reference to FIG. 28. The child seat 3001 includes a seat body 3200 and a seat belt protection device 3100 attached to the seat body 3200.

[0081] The seat body 3200 is configured to carry a child 3400 (see FIG. 31). The seat body 3200 includes an upper end portion and a lower end portion that are spaced apart from each other. The seat body 3200 is configured such that when the child 3400 is properly seated on the child seat 3001, the head portion of the child 3400 is positioned near the upper end rather than the lower end. For example, the seat body 3200 includes a seat portion 3210, a backrest portion 3220, and a headrest portion 3230 so that the child 3400 can sit stably. The child seat 3001 is placed on a vehicle seat (not shown). The vehicle seat is usually a rear seat of an automobile and includes a left rear seat and a right rear seat. The child seat 3001 is fixed to the vehicle seat via a vehicle seat belt 3300, and the connection mode of the seat belt 3300 will be described in detail later. The seat portion 3210 is disposed at the upper end of the seat body 3200, such as being connected to the upper end of the backrest portion 3220, for placing the head 3410 of the child 3400. When the child 3400 is seated on the child seat 3001, the backrest surface 3220a of the backrest portion 3220 serves to support the back of the child 3400. The backrest portion 3220 includes a pair of side wings 3220b that are spaced apart from each other, and the backrest surface 3220a is disposed between the pair of side wings 3220b.

[0082] Regarding the specific structure of the seat belt protection device 3100, reference is made to FIGS. 29 and 30 for description. The seat belt protection device 3100 includes a guide portion 3110 and a connection portion 3120. The guide portion 3110 houses a part of the seat belt 3300. The guide portion 3110 is generally formed in a groove shape that opens toward the front side of the child seat 3001.

[0083] The guide portion 3110 includes a bottom portion 3111, at least one side portion 3112, and a passage 3113.

[0084] The bottom 3111 is adjacent to the child seat 3001. In the embodiment shown in FIG. 29, the bottom 3111 extends obliquely substantially vertically downward. However, it should be understood that the seat belt protection device 3100 has a certain flexibility and can change the shape and position of any of the various components according to the shape and position of the seat belt 3300. Therefore, in other embodiments, the bottom 3111 extends in other directions.

[0085] The side portions 3112 project from the lateral ends of the bottom 3111 in a direction away from the backrest surface 3220a of the child seat 3001 and curve toward the lateral center of the bottom 3111. In the embodiment, two side portions 3112 are provided opposite to each other in the lateral direction, and the lateral distance between the two side portions 3112 is greater than half of the lateral dimension of the bottom 3111. However, it should be understood that in other embodiments, the lateral distance between the two side portions 3112 may be greater or smaller. Further, in other embodiments, only one side portion 3112 is provided.

[0086] A passage 3113 through which the seat belt 3300 extends through the seat belt protection device 3100 is formed between the bottom 3111 and the side portions 3112. The lateral dimension of the passage 3113 is slightly larger than the width of the seat belt 3300, so that the seat belt 3300 can easily pass through the passage 3113. In this embodiment, the passage 3113 is formed over the entire longitudinal length of the bottom 3111. It should be understood that in other embodiments, the passage 3113 may be formed only in a part of the length of the bottom 3111.

[0087] The connecting portion 3120 connects the guide portion 3110 to the child seat 3001. The connecting portion 3120 is configured to move laterally with respect to the child seat 3001, and the guide portion 3110 is configured to selectively be positioned on the left shoulder or the right shoulder of the child 3400, which will be described in detail later.

[0088] The connecting part 3120 includes a ball part 3122 and an extending part 3121. The ball part 3122 is slidably engaged with the slide slot 3240 of the child seat 3001. The extending part 3121 is connected between the guide part 3110 and the ball part 3122. More specifically, the slide slot 3240 is a horizontally long groove provided in the child seat 3001, for example, provided in the headrest part 3230. Therefore, when the height of the seat part 3210 or the backrest part 3220 of the headrest part 3230 is adjusted, the slide slot 3240 and the seat belt protection device 3100 engaged with the slide slot 3240 are adjusted simultaneously. The ball part 3122 and the guide part 3110 are respectively arranged on the opposite sides of the slide slot 3240. For example, the ball part 3122 is located on the rear side of the slide slot 3240 (that is, the side facing away from the child 3400 of the child seat 3001 when the child 3400 is seated on the child seat 3001), and the guide part 3110 is located on the front side of the slide slot 3240 (that is, the side facing the child 3400 of the child seat 3001 when the child 3400 is seated on the child seat 3001). The extending part 3121 passes through the slide slot 3240 to connect the ball part 3122 and the guide part 3110. In the embodiment, the slide slot 3240 is provided on at least one of the backrest surface 3220a or the side wing 3220b of the backrest part 3220, for example.

[0089] The diameter of the ball part 3122 is larger than the width of the slide slot 3240 and is locked at either end of the slide slot 3240. In the embodiment shown in FIG. 29, the ball part 3122 is locked at the left end of the slide slot 3240, that is, at the left shoulder of the child 3400 (see FIG. 31).

[0090] In an embodiment, the ball portion 3122, the extending portion 3121, and the guide portion 3110 are formed as an integral structure, for example, injection molded, so as to simplify the manufacturing process. In an embodiment, the guide portion 3110 is made of an energy absorbing material, for example, a cloth covered with a foam, or a thermoplastic material such as TPE, TPR, TPU, TPV, TPO, TPEE, or silicone.

[0091] The use of the seat belt protection device 3100 will be described with reference to FIG. 31.

[0092] When in use, the child 3400 sits on the child seat 3001 with the head 3410 on the headrest part 3230 and the body on the seat part 3210 and the backrest part 3220. The first end 3310 of the vehicle seat belt 3300 is connected to a vehicle seat (not shown). The vehicle seat is usually arranged behind the child seat 3001, but the present disclosure is not limited thereto. Taking FIG. 31 as an example, the child seat 3001 is fixed to the left rear seat of the vehicle. When in use, the seat belt 3300 on the left side of the vehicle is connected to an insert buckle (not shown) of the vehicle seat via a belt buckle (not shown). The belt buckle divides the seat belt 3300 into a shoulder belt and a waist belt. The shoulder belt diagonally crosses the left shoulder and the right waist of the child 3400, and the waist belt horizontally crosses the waist of the child 3400. The shoulder belt of the seat belt 3300 extends from the first end 3310 around or through the child seat 3001 to the shoulder 3420 of the child 3400, extends obliquely downward to the waist side of the torso of the child 3400, and is connected to a vehicle seat (not shown) by the belt buckle at the waist side of the torso of the child 3400. The waist belt of the seat belt 3300 further extends horizontally to the second end 3320 on the opposite side of the waist of the body of the child 3400, and is connected to a vehicle seat (not shown) at the second end 3320. Therefore, it can be understood that the upper part of the shoulder belt of the seat belt 3300 extends obliquely around one shoulder 3420 of the child 3400. Without the seat belt protection device 3100, when the vehicle is impacted, the shoulder belt of the seat belt 3300 may slide over the neck of the child 3400, and the child 3400 may suffer from strangulation or facial injury.

[0093] Thanks to the seat belt protection device 3100 of the embodiment of the present disclosure, a part of the seat belt 3300 corresponding to the shoulder 3420 passes through the passage 3113. Due to the obstruction of the seat belt protection device 3100, the seat belt 3300 does not easily slide from the shoulder 3420 to the neck. Further, the seat belt protection device 3100 functions as a buffer device between the seat belt 3300 and the child 3400, can reduce the impact force of the child 3400 in a collision accident, and improve the safety performance.

[0094] In the embodiment shown in FIG. 31, the child seat 3001 is installed on the seat on the left side of the vehicle. In such a case, the first end 3310 and the second end 3320 of the seat belt 3300 are located on the left side of the child 3400 (since FIG. 31 shows the child 3400 and the child seat 3001 in a mirror image, the left side of the child 3400 refers to the right side of the child 3400), the belt buckle is located on the right side of the child 3400 (i.e., the left side in FIG. 31), and thus, the seat belt 3300 extends around the left shoulder 3420 of the child 3400. In this case, the connecting portion 3120 of the seat belt protection device 3100 is configured to move to the left side of the child seat 3001 (i.e., the left end of the slide slot 3240), and the guide portion 3110 can extend obliquely from the upper left to the lower right so as to adapt to the extending direction of the seat belt 3300.

[0095] Referring to FIGS. 32 and 33, FIGS. 32 and 33 show a situation where the seat belt protection device 3100 is arranged on the right side of the child seat 3001. In this case, the extending direction of the seat belt 3300 refers to the horizontal mirror of the embodiment shown in FIG. 31, that is, the seat belt extends obliquely around the right shoulder 3420 of the child 3400.

[0096] In order to match the extending direction of the seat belt 3300, the connecting portion 3120 of the seat belt protection device 3100 moves to the right side of the child seat 3001 (i.e., the left side in FIGS. 32 and 33), that is, slides to the right end of the slide slot 3240. The guide portion 3110 extends obliquely from the upper right to the lower left in accordance with the extending direction of the seat belt 3300.

[0097] According to the seat belt protection device 3100 of the present disclosure, it can be seen that a single seat belt protection device 3100 is provided to adapt to the usage requirements of the left connection part (FIGS. 28, 29 and 31) and the right connection part (FIGS. 32 and 33) of the seat belt 3300. Therefore, the seat belt protection device 3100 and the child seat 3001 having the same have improved flexibility in use.

[0098] Referring to FIGS. 34 and 35, the connection between the seat belt protection device 3100 and the child seat 3001 is further shown. The guide part 3110 and the ball part 3122 of the seat belt protection device 3100 are arranged on both sides of the slide slot 3240 respectively.

[0099] The protrusion 3241 of the slide slot 3240 will be described with reference to FIG. 36. The slide slot 3240 is provided with at least one protrusion 3241 in order to limit the ball part 3122 at any end of the slide slot 3240. The protrusion 3241 extends vertically from at least one of the upper lateral end and the lower lateral end of the slide slot 3240 towards the inside of the slide slot 3240, and a gap is formed between the protrusion 3241 and any end of the slide slot 3240. In an embodiment, a pair of protrusions 3241 are provided near each lateral end of the slide slot 3240 (only a pair of protrusions are shown in FIG. 36), and each pair of protrusions 3241 are respectively arranged on two longitudinal side surfaces of the slide slot 3240 and face each other.

[0100] Another embodiment of the seat belt protection device 3100 according to the present disclosure will be described with reference to FIGS. 37 and 38. The guide part 3110 of the other embodiment is substantially the same as the guide part 3110 of the previous embodiment, but the connection part 3120 has a different structure.

[0101] In another embodiment, the connecting portion 3120 includes an engaging element 3124 and a connecting belt 3123. The engaging element 3124 is slidably engaged with the slide slot 3240 of the child seat 3001. More specifically, the engaging element 3124 is disposed on the rear side of the slide slot 3240 of the seat body 3200.

[0102] The connecting belt 3123 is connected between the guide portion 3110 and the engaging element 3124 and passes through the slide slot 3240. For example, the connecting belt 3123 is a fabric, one end of which is sewn to the guide portion 3110, and the other end extends around the engaging element 3124 and is then sewn to the connecting belt 3123 itself.

[0103] The specific structure of the engaging element 3124 will be described with reference to FIG. 39. The engaging element 3124 has a general three-rod shape, that is, a rectangle having a horizontal line in the center. Specifically, the engaging element 3124 includes a first lateral portion 3124a, two second lateral portions 3124c facing each other, and two vertical portions 3124b facing each other. The first lateral portion 3124a is located at the vertical center of the engaging element 3124, and the connecting belt 3123 extends around the first lateral portion 3124a. The second lateral portions 3124c are located on each of the vertical sides of the first lateral portion 3124a, and each of the second lateral portions 3124c extends over the entire lateral dimension of the engaging element 3124 or is interrupted at the lateral middle portion. An embodiment in which the second lateral portion 3124c is interrupted at the lateral middle portion is shown in FIG. 39. Each of the vertical portions 3124b is connected to one end of the first lateral portion 3124a at its middle and to one end of one of the second lateral portions 3124c at its both ends.

[0104] In another embodiment, at least one protrusion 3241 is provided in the slide slot 3240 to lock the engagement element 3124 at either end of the slide slot 3240. More specifically, the length of the vertical portion 3124b of the engagement element 3124 is greater than the vertical width of the slide slot 3240, enabling the engagement element 3124 to slide along the slide slot 3240 without passing through the slide slot 3240. The distance between the protrusion 3241 and the end of the slide slot 3240, i.e., the distance between two opposing protrusions 3241, is slightly smaller than the width of the first horizontal portion 3124a of the engagement element 3124, allowing the engagement element 3124 to be forcibly pulled through the position of the protrusion(s) 3241 so that the engagement element 3124 is switchable between the left end and the right end of the slide slot 3240.

[0105] According to an embodiment of the present disclosure, the headrest portion 3230 of the seat body 3200 is configured to adjust its position relative to the seat portion 3210. For example, it moves up and down relative to the seat portion 3210 to adapt to the height of the child 3400.

[0106] The seat belt protection device 3100 is connected to the seat portion 3210 or the headrest portion 3230. For example, FIGS. 34 and 35 show an embodiment in which the seat belt protection device 3100 is connected to the headrest portion 3230. In such an embodiment, when the position of the headrest portion 3230 is adjusted relative to the seat portion 3210, the position of the seat belt protection device 3100 is adjusted together with the headrest portion 3230, thereby automatically adapting to the height of the child 3400 so as to be positioned on the shoulder 3420 of the child 3400 (see FIG. 31).
