[0033] Figures 1 to 3 1 shows a perspective view of a child safety seat 100 provided according to an embodiment of the present invention. The child safety seat may include a base 9 and a seat shell 1 disposed on the base 9. A connection assembly 2 and a belt system 3 may be mounted on the seat shell 1.

[0034] The base 9 can be placed on a vehicle seat (not shown) and provide a stable support for the seat shell 1. In some embodiments, the seat shell 1 can be adjusted in angle relative to the base 9. The seat shell 1 is configured to be a seat shape for accommodating children, and can be installed on a vehicle seat (not shown) in a forward or rearward manner, for example. When the seat shell 1 is installed on the vehicle seat in a forward manner, the sight of the child riding therein is toward the front of the vehicle, and when the seat shell 1 is installed on the vehicle seat in a rearward manner, the sight of the child riding therein is toward the rear of the vehicle. Of course, in some embodiments, the seat shell 1 can, for example, only be installed on the vehicle seat in a forward manner, or only be installed on the vehicle seat in a rearward manner.

[0035] See also Figure 3 The seat shell 1 may include a seat portion 13 and a backrest portion 14. The seat shell 1 may be a plastic molding, and a foam plastic 17 (see Figure 8 ) so that the seat shell 1 has a cushioning performance. Figure 1 The inner side of the seat shell 1 and the foam plastic 17 facing the child can be covered by a flexible covering 16, such as a seat cloth. A cushioning filler can also be filled between the flexible covering 16, the seat shell 1, and the foam plastic 17, such as a sponge layer.

[0036] See also Figure 1 and Figure 3 The seat portion 13 is used to support the child's hips, and the backrest portion 14 is used to support the child's back. In some embodiments, the seat portion 13 and the backrest portion 14 may include, for example, an integral injection molded part. Upwardly raised side wings 131 may be provided on both sides of the seat portion 13, and forwardly extending side wings 141 may be provided on both sides of the backrest portion 22. The foam plastic 17 is, for example, mainly attached to the inner sides of these side wings, which can better position the child in the seat shell 1. A headrest 19 may be provided on the backrest portion 14, and the height of the headrest 19 can be adjusted to adapt to the child's sitting height. See FIG. Figure 3 , shoulder strap holes 140 may also be provided on the headrest 19. In some embodiments, a plurality of ventilation holes 145 may also be provided on the headrest 19.

[0037] See also Figure 1 and Figure 3 , a belt system 3 is attached to the seat shell 1 for restraining a child in the seat shell 1. The belt system 3 may include two shoulder straps 31, an adjustment belt 32 and a crotch belt 33.

[0038] The two shoulder straps 31 may be arranged symmetrically with respect to the longitudinal center plane S of the seat shell. The first end 311 of each shoulder strap 31 is attached to the seat portion 13, and the second end (not shown in the figure) of each shoulder strap 31 passes through the shoulder strap hole 140 of the headrest 19 and extends downward behind the backrest portion 14, and may be connected to one end of the adjustment strap 32 by any suitable connector (not shown in the figure). The other end of the adjustment strap 32 extends forward in the seat portion 13 and extends out from the opening 130. A buckle 34 may be provided in the middle of each shoulder strap 31. The first end of the crotch strap 33 is attached to the seat portion 13, and the second end of the crotch strap 33 is provided with a buckle 35.

[0039] When a child sits in the seat shell 1, the buckles 34 of the two shoulder straps 31 are buckled with the buckles 35 of the crotch strap 33, and then the adjustment belt 32 is pulled to increase the length of the adjustment belt 32 extending out of the opening 130, so that the length of each shoulder strap 31 in front of the backrest portion 14 can be reduced to tighten the child, and the child is reliably restrained in the seat shell 1. The seat portion 13 is also provided with a locking mechanism 137 for locking the adjustment belt 32. When the locking mechanism 137 is in a locked state, the adjustment belt 32 is allowed to be pulled out of the opening 130 to tighten the shoulder belt 31, but the adjustment belt 32 is not allowed to retract into the opening 130 (the retraction of the adjustment belt 32 into the opening 130 is achieved by pulling the shoulder belt 31), so as to avoid the shoulder belt 31 being loosened due to the retraction of the adjustment belt 32 into the opening 130. When the locking mechanism 137 is in a released state, the adjustment belt 32 can be pulled out of the opening 130 or retracted into the opening 130.

[0040] It should be noted that, unless otherwise clearly specified and limited, the directional terms such as "left" and "right" in the embodiments of the present invention are based on the "left" and "right" directions of the child sitting in the child safety seat 100, and the "left" and "right" directions are schematically shown by arrows L and R in the figure. These directional terms are only used to make the description of the embodiments of the present invention clearer and are not used to improperly limit the scope of protection of the present invention.

[0041] See also Figure 1 and Figure 3 A connection assembly 2 is provided on the left and right sides of the seat shell 1. The connection assembly 2 includes a connection belt 21 and a connector 22. The connection belt 21 is, for example, a webbing, a first end 211 of the connection belt 21 is connected to the seat shell 1, and a second end 212 of the connection belt 21 is connected to the connector 22. The connector 22 is, for example, a LATCH connector, which can be detachably connected to a connector on a vehicle seat, thereby fixing the child safety seat on the vehicle seat.

[0042] See also Figure 2 In this embodiment, the outer side surfaces 11 of the left and right sides of the seat shell 1 are provided with connecting through holes 110. The first end 211 of the connecting belt 21 enters the inner space 10 surrounded by the outer side surfaces 11 of the seat shell 1 through the corresponding connecting through holes 110 (see Figure 3) is limited, thereby realizing the connection between the connecting belt 21 and the seat shell 1. The first end 211 of the connecting belt 21 can be limited in any suitable manner, as long as the first end 211 of the connecting belt 21 cannot be pulled out through the connecting through hole 110. In some embodiments, the connecting through hole 110 can be an arc-shaped slit, and the first end 211 of the connecting belt 21 can be limited by any suitable structure after entering the internal space 10 from the slit. In addition, the connecting through hole 110 allows the connecting belt 21 to slide back and forth in the connecting through hole 110 to adapt to the specific installation direction of the seat shell 1 on the vehicle seat. In some embodiments, the connector 22 is detachably connected to the second end 212 of the connecting belt 21, for example, through an adjuster 23, and the adjuster 23 can adjust the length of the connecting belt 21.

[0043] Continue to see Figure 2 In some embodiments, the seat shell 1 may also be attached with a top tether assembly 5, which is used to connect the upper part of the seat shell 1 to the anchor point inside the vehicle to further ensure the connection stability between the child safety seat 100 and the vehicle seat. The top tether assembly 5, for example, includes two first tethers 51 and one second tether 52. The first ends of the two first tethers 51 are respectively connected to the left and right sides of the outer side surface 11 of the seat shell 1, and the second ends of the two first tethers 51 are connected to the first end of the second tether 52 after passing over the top of the vehicle seat (not shown in the figure), and the second end of the second tether 52 is provided with an anchor 53, which is used to connect to the above-mentioned anchor point. The anchor 53 may be, for example, but not limited to, a hook. Of course, in some embodiments, the second tether 52 may also be formed by extending one of the first tethers 51.

[0044] In the connection assembly 2 provided in the embodiment of the present invention, after the first end 211 of the connection belt 21 enters the internal space 10 through the connecting through hole 110, it is limited by being directly or indirectly connected to the seat shell 1. Therefore, there is no need to provide a mounting seat for fixing the connection belt 21 on the outer side surface 11 of the seat shell 1, thereby avoiding harm to other passengers due to the provision of the mounting seat, and simplifying the structure of the seat shell 1, so that the seat shell 1 has a neat appearance.

[0045] Figures 3 to 5 A limiting method of the first end 211 of the connecting belt 21 is shown. Figures 6 to 9The seat portion 13 is provided with a first hole 101, a second hole 102 and a third hole 103, which can be arranged side by side and close to the backrest portion 14. In some embodiments, the first hole 101 is located between the second hole 102 and the third hole 103, and the second hole 102 is closer to the longitudinal center plane S of the seat shell 1 than the third hole 103. The connecting through hole 110 is farther away from the longitudinal center plane S than the third hole 103. The first end 211 of the connecting belt 21 passes through the connecting through hole 110 (see Figure 8 and Fig. 9 ) and then pass through the third hole 103 from top to bottom, and then pass through the first hole 101 from bottom to top, and then connect with the first limiter 41 located above the first hole 101. The size of the first limiter 41 is larger than the size of the first hole 101, and the first limiter 41 is, for example, a Japanese buckle, a mesh buckle, or other suitable components. The first limiter 41 abuts against the edge of the first hole 101, which can limit the position of the first end 211 of the connecting belt 21, thereby realizing the connection between the connecting belt 21 and the seat shell 1.

[0046] The first end 311 of the shoulder strap 31 passes through the first hole 101 from top to bottom, and then passes through the second hole 102 from bottom to top, and then connects with the second stopper 42 located above the second hole 102. The size of the second stopper 42 is larger than the size of the second hole 102, and the second stopper 42 is, for example, a Japanese buckle, a mesh buckle, or other suitable components. The second stopper 42 abuts against the edge of the second hole 102, which can limit the position of the first end 311 of the shoulder strap 31, and realize the connection between the first end 311 of the shoulder strap 31 and the seat shell 1.

[0047] See also Figure 5 , the shoulder strap 31 is connected to the first stopper 41 when passing through the first stopper 41, so that the shoulder strap 31 and the connecting strap 21 are connected through the first stopper 41. When the child safety seat 100 is in use, the connecting strap 21 and the shoulder strap 31 are both tensioned, the first stopper 41 is subjected to a first downward pulling force from the connecting strap 21, and at the same time, the first stopper 41 is subjected to a second upward pulling force from the shoulder strap 31. The first pulling force and the second pulling force in opposite directions can partially offset each other to reduce the pressure applied by the first stopper 41 to the edge of the first hole 101, thereby improving the stress concentration at the connection between the seat portion 13 and the connecting strap 21 and the shoulder strap 31, and ensuring the structural strength of the connection.

[0048] See also Figure 4 and Figure 5 , the seat portion 13 may also be provided with a groove 132 for positioning the second limiting member 42. In some embodiments, the seat portion 13 may also be provided with a groove for positioning the first limiting member 41.

[0049] Fig.10Another limiting method of the first end 211 of the connecting belt 21 is shown. Specifically, the seat portion 13 is provided with a first hole 101 and a fourth hole 104, and the first hole 101 and the fourth hole 104 can be arranged side by side and close to the backrest portion 14. In some embodiments, the fourth hole 104 is closer to the longitudinal center plane S of the seat shell 1 than the first hole 101. The connecting through hole 110 is farther away from the longitudinal center plane S than the first hole 101. After the first end 311 of the shoulder strap 31 passes through the fourth hole 104 from top to bottom, it passes through the first hole 101 from bottom to top, and then connects with the first limiting member 41 located above the first hole 101. The size of the first limiting member 41 is larger than the size of the first hole 101, and the first limiting member 41 is, for example, a Japanese buckle, a mesh buckle or other suitable components. The first limiting member 41 abuts against the edge of the first hole 101, which can limit the position of the first end 311 of the shoulder strap 31, and realize the connection between the shoulder strap 31 and the seat shell 1. The first end 211 of the connecting belt 21 passes through the connecting through hole 110 and then extends downward and is connected to the first stopper 41, so that the first end 211 of the connecting belt 21 is stopped. When the child safety seat is in use, the tensioned shoulder straps 31 and the connecting belt 21 exert opposite pulling forces on the first stopper 41, which can improve the stress concentration at the connection between the seat portion 13 and the connecting belt 21 and the shoulder strap 31.

[0050] Fig.11 Another limiting method of the first end 211 of the connecting belt 21 is shown. The seat portion 13 is provided with a first hole 101 and a fifth hole 105, and the first hole 101 and the fifth hole 105 can be arranged side by side and close to the backrest portion 14.

In some embodiments, the third hole 103 is located between the first hole 101 and the second hole 102, and the second hole 102 is closer to the longitudinal center plane S of the seat shell 1 than the first hole 101. In combination with the foregoing, it can be known that the connecting through hole 110 is farther away from the longitudinal center plane S than the first hole 101. After passing through the connecting through hole 110, the first end 211 of the connecting belt 21 passes through the third hole 103 from top to bottom, and then passes through the first hole 101 from bottom to top, and then connects with the first limiting member 41 located above the first hole 101. The size of the first limiting member 41 is larger than the size of the first hole 101, and the first limiting member 41 is, for example, a Japanese buckle, a mesh buckle or other suitable components. The first limiting member 41 abuts against the edge of the first hole 101 , and can limit the position of the first end 211 of the connecting belt 21 , thereby achieving the connection between the connecting belt 21 and the seat shell 1 .

[0053] The first end 311 of the shoulder strap 31 passes through the third hole 103 from top to bottom, and then passes through the second hole 102 from bottom to top, and then is connected to the second stopper 42 located above the second hole 102. The size of the second stopper 42 is larger than the size of the second hole 102, and the second stopper 42 is, for example, a Japanese buckle, a mesh buckle, or other suitable components. The second stopper 42 abuts against the edge of the second hole 102, which can limit the position of the first end 311 of the shoulder strap 31, and realize the connection between the first end 311 of the shoulder strap 31 and the seat shell 1.

[0054] Fig.14Another limiting method of the first end 211 of the connecting belt 21 is shown. The seat portion 13 is provided with a second hole 102 and a third hole 103, and the second hole 102 and the third hole 103 can be arranged side by side and close to the backrest portion 14. In some embodiments, the second hole 102 is closer to the longitudinal center plane S of the seat shell 1 than the third hole 103. In combination with the foregoing, it can be known that the connecting through hole 110 is farther away from the longitudinal center plane S than the third hole 103. The first end 311 of the shoulder strap 31 passes through the third hole 103 from top to bottom, and then passes through the second hole 102 from bottom to top, and then connects with the second limiting member 42 located above the second hole 102. The size of the second limiting member 42 is larger than the size of the second hole 102, and the second limiting member 42 is, for example, a Japanese buckle, a mesh buckle or other suitable components.
