Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features.

[0029] The utility model embodiment provides a length adjustable cross part safety belt, in combination Figures 1-9 As shown in the figure, it comprises a seat 3 and a cross part safety belt 1, the cross part safety belt 1 is connected with adjusting buckle 2 for adjusting length, the adjusting buckle 2 is suitable for being installed on the seat 3, the adjusting buckle 2 includes a plurality of first gear holes 21, a plurality of first gear holes 21 are distributed from the direction close to the cross part to the direction away from the cross part, the first gear hole 21 is communicated with the first passage 22 between adjacent first gear holes 21, the cross part safety belt 1 passes through different first gear holes 21 through the first passage 22, to adjust the length of the cross part safety belt 1.

[0030] As Figure 2 shown in the figure, in the embodiment, the adjusting buckle 2 is sewn at the lower end of the cross part safety belt 1, the first gear hole 21 has four, the first passage 22 has three, the four first gear holes 21 are arranged at intervals, and the first passage 22 is arranged at the middle position of the first gear hole 21. The first gear hole 21 is approximately rectangular, when the length of the cross part safety belt 1 is not adjusted, the cross part safety belt 1 is limited in the first gear hole 21, to ensure safety.

[0031] The adjustable crossbody seat belt of this utility model has an adjustment buckle 2 on the crossbody seat belt 1. The adjustment buckle 2 has several first position holes 21 and first passageways 22 that cooperate with each other. By utilizing the flexible nature of the seat belt, the seat belt can be folded and passed through the first passageway 22 into different first position holes 21, thereby adjusting the length. The structure is simple and easy to operate, ensuring the comfort and safety of children.

[0032] Optionally, the adjusting buckle 2 includes a fixing hole 23, which is spaced apart from the first gear hole 21. The cross-body safety belt 1 passes through both the fixing hole 23 and the first gear hole 21. The gap between the fixing hole 23 and the first gear hole 21 is used to fix the position of the cross-body safety belt 1.

[0033] like Figure 2 As shown, in this embodiment, the fixing hole 23 is located at one end of the adjusting buckle 2 near the crotch, and the fixing hole 23 is approximately rectangular. The crotch safety belt 1 changes its length by adjusting the distance between itself and the fixing hole 23 through different first stop holes 21.

[0034] like Figure 2 As shown, optionally, an "I" shape can be formed between any two adjacent first gear holes 21.

[0035] like Figure 4 As shown, optionally, the upper end of the cross-body seat belt 1 is connected to a buckle 11, the upper end of the buckle 11 is connected to an insert of the shoulder seat belt 4, and the adjusting buckle 2 is connected to the lower end of the cross-body seat belt 1.

[0036] like Figure 1 As shown, in this embodiment, the child safety seat includes not only the cross-body seat belt 1, but also the shoulder seat belt 4. The shoulder seat belt 4 and the cross-body seat belt 1 are detachably connected by a buckle 11 and an insert. The buckle 11 and the adjusting buckle 2 are respectively located at both ends of the cross-body seat belt 1.

[0037] Optionally, the plurality of first gear holes 21 are parallel to each other, and the first passageway 22 is inclined and is used to guide the cross-body seat belt 1 into different first gear holes 21.

[0038] like Figure 5 and 7 As shown, in this embodiment, the inclined first aisle 22 allows the cross-body seat belt 1 to slide along the inclined surface into different first gear holes 21 to adjust the gear after folding. Compared to the vertically arranged first aisle 22, the inclined arrangement makes the adjustment process smoother.

[0039] Optionally, the seat 3 is provided with a seat belt inlet 31 and a mounting groove 32. The mounting groove 32 is provided with a seat belt outlet 321. The adjusting buckle 2 drives the cross-body seat belt 1 to pass through the seat belt inlet 31 into the lower part of the seat 3, and then pass out from the seat belt outlet 321 to the upper part of the seat 3. The adjusting buckle 2 is limited and installed in the mounting groove 32.

[0040] like Figures 3-5 As shown, in this embodiment, the seat belt outlet 321 is located in the mounting groove 32, so that the adjusting buckle 2 can be inserted into the mounting groove 32 after it passes through the seat belt outlet 321 and is flipped over.

[0041] Optionally, the lengths of the seat belt inlet 31 and the seat belt outlet 321 are both adapted to the length of the adjusting buckle 2.

[0042] like Figures 7-8 As shown, the adjusting buckle 2 is approximately a flat cuboid, and both the seat belt inlet 31 and the seat belt outlet 321 are rectangular to accommodate the shapes of the adjusting buckle 2 and the cross-belt 1.

[0043] Optionally, it also includes a seat belt inlet 31, which includes a plurality of second stop holes 311 distributed from near the crotch to away from the crotch. Adjacent second stop holes 311 are connected by a second passageway 312. The crotch seat belt 1 passes through different second stop holes 311 via the second passageway 312 to adjust the front and rear position of the crotch seat belt 1.

[0044] like Figure 5 and 9 As shown, in this embodiment, the second shift hole 311 is closer to the crotch area than the first shift hole 21. There are two second shift holes 311, forming an "I" shape. The second shift holes 311 also utilize the flexible nature of the seat belt; after folding, the seat belt passes through the second passageway 312 and enters different second shift holes 311, thus adjusting the front and rear positions of the seat belt 1 in the crotch area. The structure is simple, the operation is convenient, and it ensures the comfort and safety of the child.

[0045] In other embodiments, there may be two or more second gear holes 311. Optionally, any two adjacent second gear holes 311 may form an "I" shape.

[0046] Another embodiment of the present invention provides a child safety seat, including a cross-belt with adjustable length as described above.
