For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0032] This embodiment provides a safety seat that can be used in both directions. Figure 1 and Figure 2 As shown, the safety seat comprises a base 1 and a seat back 2, wherein the seat back 2 is movably connected to the base 1, and the angle between the seat back 2 and the base 1 is adjustable between an acute angle and an obtuse angle, so that the safety seat can be switched between forward installation and reverse installation.

[0033] In normal use, that is, when used in the forward direction, the angle between the backrest and the base is an obtuse angle, and the child lies on the front of the backrest; when the child's direction needs to be changed, the backrest can be rotated to make the angle between the backrest and the base an acute angle, so that the child can be placed on the back of the backrest. The forward and reverse use safety seat provided by the present invention can be switched between forward and reverse use states at will through the folding and flipping of its own structure, and there is no need to disassemble the safety seat to change the direction. The operation is simple and convenient, and it is suitable for customers with more requirements.

[0034] The structure of the chair back 2 is described in detail below:

[0035] In some embodiments, Figure 1 As shown, the chair back 2 includes a backrest body 21 and side wings 22 located on both sides of the backrest body 21 . The side wings 22 are rotatably disposed on the backrest body 21 so that the side wings 22 can be located on the front or back side of the backrest body 21 .

[0036] When the above-mentioned forward-reversible safety seat is used in the forward direction, the side wings 22 are located in front of the backrest body 21 to protect the two sides of the child in front of the backrest body 21; when the above-mentioned forward-reversible safety seat is used in the reverse direction, such as Figure 4 As shown, the side wings 22 are flipped over the back of the backrest body 21 to protect both sides of the child on the back of the backrest body 21 .

[0037] The seat back 2 can provide more comprehensive protection for children. Figure 1 and Figure 6 As shown, whether it is used in the front or back state, it can achieve the same protective effect, and it is safer and more reliable to use.

[0038] In some embodiments, the safety seat further comprises a headrest 3 located between the two side wings 22 , and the headrest 3 is rotatably connected to the backrest body 21 so that the headrest 3 can be located on the front or back of the seat back 2 .

[0039] Under normal use, such as Figure 1As shown, the headrest 3 is located in front of the backrest body 21 to block the head of the child in front of the backrest body 21; when the child's orientation needs to be changed, such as Figure 6 As shown, the headrest 3 is rotated so that the headrest can block the child's head on the back of the backrest body 21. The above arrangement enables the safety seat to fully protect the child whether it is in the front use state or the back use state.

[0040] Specifically, Figure 2 As shown, the rotation axis of the wing 22 is perpendicular to the rotation axis of the headrest 3 .

[0041] The rotation axis of the side wing 22 is parallel to the side of the backrest body 21, and the rotation axis of the headrest 3 is perpendicular to the side of the backrest body 21. In other words, the side wing 22 is flipped from the side of the backrest body 21 to the front or back of the chair back 2, and the headrest 3 is flipped upward or downward relative to the backrest body 21, thereby flipping to the front or back of the chair back 2.

[0042] Specifically, a support shaft is respectively provided on both sides of the backrest body 21 , and a side wing 22 is respectively provided on both sides of the backrest body 21 , and the side wing 22 is rotatably connected to the support shaft.

[0043] It should be noted that the rotation of the wing 22 can be achieved manually or electrically.

[0044] When it is necessary to realize it manually, the support shaft can be tightly matched with the side wing 22, so that after the side wing 22 is turned over, it can be stably stationary on the front or back of the backrest body 21. The support shaft can also be a damping support shaft to prevent the side wing 22 from having a strong impact with the backrest body 21 when rotating.

[0045] When it is necessary to realize it by electricity, a driving component such as a micro motor can be installed on the backrest body 21, and the driving component is connected to the side wing 22 to drive the side wing 22 to rotate.

[0046] The side wing 22 can be limited by its own structure, that is, when it rotates to the front of the backrest body 21, its end close to the backrest body 21 abuts against the front of the backrest body 21, and vice versa, it abuts against the back of the backrest body 21, thereby limiting its own rotation angle. Of course, the side wing 22 can also be limited by other structures, such as a limit stopper on the backrest body 21, etc.

[0047] In some embodiments, the wing 22 can rotate through an angle of at least 180°.

[0048] The above angle setting enables the side wings 22 to be fully rotated to the front or back of the chair back 2, thereby fully shielding both sides of the child.

[0049] Specifically, the rotation angle of the side wing 22 can be 180°, 190°, 200° or 210°, etc. The user can adjust the rotation angle of the side wing 22 as needed.

[0050] A preferred solution of the safety seat for forward and reverse use is described in detail below:

[0051] In some embodiments, Figure 3 As shown, an adjustment component 4 is provided between the base 1 and the chair back 2 , and the adjustment component 4 is used to adjust the rotation angle of the chair back 2 relative to the base 1 .

[0052] Compared with other methods such as tight fit, the rotation angle of the seat back 2 is adjusted by the adjustment component 4, which is more stable and effectively ensures the safety of children.

[0053] Specifically, Figure 3 As shown, the adjustment component 4 includes a slot 41 provided on the base 1 and a locking component 42 provided on the chair back 2. The slot 41 has at least two positions, and the locking component 42 is used to be locked in any one of the positions.

[0054] One locking position corresponds to one static angle of the chair back 2 , and multiple locking positions mean that the chair back 2 can have multiple static angles.

[0055] The above-mentioned adjustment component 4 has a simple structure and is easy to operate. When the locking component 42 is locked in the locking position, the position of the seat back 2 relative to the base 1 is locked. When the locking component 42 is out of the locking position, the position of the seat back 2 relative to the base 1 is unlocked.

[0056] In some embodiments, the slot 41 further includes a slideway, which is connected to each locking position, and the locking assembly 42 includes a locking rod and a locking button connected to the locking rod. When the chair back 2 is rotated to a preset angle, the locking button is pressed, and the locking rod is locked in the locking position corresponding to the angle; when the angle of the chair back 2 needs to be repeatedly adjusted, the locking button is pulled out, and the locking rod moves to the slideway, canceling the locking state of the chair back 2.

[0057] In some other embodiments, the locking assembly 42 only includes a locking rod, one end of which is connected to the chair back 2 through a universal joint, and the other end is used to engage with a locking position. When the chair back 2 is rotated to a preset angle, the locking rod is manually rotated to engage with the locking position corresponding to the angle; when the angle of the chair back 2 needs to be repeatedly adjusted, the locking rod on the locking position is manually removed, the chair back 2 is rotated to another angle, and then the free end of the locking rod is engaged with the locking position corresponding to the angle.

[0058] The rotation principle of the headrest 3 is specifically described below:

[0059] Specifically, Figure 2As shown, a through slot 23 is provided on the seat back 2 , and the headrest 3 can pass through the through slot 23 and rotate to the front or back side of the seat back 2 .

[0060] The through slot 23 provides an escape space for the rotation of the headrest 3 , and the seat back 2 will not cause any obstruction to the headrest 3 , thus facilitating the operation of the user.

[0061] It should be noted that the width of the through slot 23 is not less than the width of the headrest 3 , and the length of the through slot 23 is not less than the length of the headrest 3 , so that the headrest 3 can smoothly rotate to the back of the seat back 2 through the through slot 23 .

[0062] like Figure 2 As shown, two headrests 3 are rotatably mounted on the seat back 2. In order to make the above-mentioned safety seat structure for forward and reverse use simpler, a connecting shaft is provided in the inner cavity on the back of the seat back 2, and the two headrests 3 are rotatably connected to one connecting shaft together.

[0063] In order to make the position of the headrest 3 relative to the seat back 2 more stable before and after flipping, Figure 2 and Figure 5 As shown, a limiting component is provided on the headrest 3 , and the limiting component is used to limit the position of the headrest 3 relative to the seat back 2 .

[0064] Compared with limiting the position of the headrest 3 by tightly connecting the headrest 3 with the connecting shaft, setting a limit assembly is more reliable and stable and will not loosen.

[0065] It should be noted that any structure that can limit the position of the headrest 3 relative to the seat back 2 can be the position limiting assembly mentioned in the above embodiment. For example, the position limiting assembly can include a buckle provided on the headrest 3 and a slot provided on the seat back 2, or the position limiting assembly can include a bolt and a nut.

[0066] In at least one embodiment, Figure 2 As shown, the limit assembly includes a locking knob 5 rotatably connected to the headrest 3, the locking knob 5 is located on the side of the seat back 2 away from the headrest 3, the width of the locking knob 5 is smaller than the width of the through slot 23, and the length of the locking knob 5 is greater than the width of the through slot 23.

[0067] The position of the headrest 3 can be limited or released by turning the locking knob 5 . No auxiliary tools are needed in the whole process, making the operation easier.

[0068] Specifically, two locking knobs 5 are installed on one headrest 3, one locking knob 5 is connected to the upper part of the headrest 3, and the other locking knob 5 is connected to the lower part of the headrest 3, so as to achieve a two-way limiting effect on the headrest.

[0069] by Figure 2 and Figure 5Taking the locking knob 5 as an example, the working principle of the locking knob 5 is specifically described:

[0070] like Figure 2 As shown, this is the structural state of the locking knob 5 when used from the front. At this time, the two locking knobs 5 are located on the back side of the seat back 2 and are arranged horizontally, that is, the length direction of the two locking knobs 5 is parallel to the width direction of the through slot 23. Since the length of the locking knobs 5 is greater than the width of the through slot 23, the headrest 3 cannot pass through the through slot 23 under the limitation of the two locking knobs 5 and is locked on the front side of the seat back 2; when the headrest 3 needs to be rotated, the two locking knobs 5 are rotated 180° so that the two locking knobs 5 are arranged longitudinally, and then the headrest 3 is rotated, and the two locking knobs 5 also follow the headrest 3 through the through slot 23; as shown in FIG. Figure 5 As shown, after the headrest 3 is located on the back side of the seat back 2, the two locking knobs 5 are located on the front side of the seat back 2, and then the two locking knobs 5 are rotated 180° to restore to the horizontal state, thereby locking the headrest 3 on the back side of the seat back 2.

[0071] In some embodiments, the rotation angle of the headrest 3 is at least 180°.

[0072] The above angle setting enables the headrest 3 to be fully rotated to the front or back of the seat back 2, thereby fully protecting both sides of the child's head.

[0073] Specifically, the rotation angle of the headrest 3 can be 180°, 190°, 200° or 210°, etc. The user can adjust the rotation angle of the headrest 3 as needed.

[0074] To sum up, the above-mentioned forward-and-reversible safety seat can be used in both forward and reverse directions and has good market prospects. Without disassembling the seat, the forward and reverse directions of the seat can be naturally switched through the folding and flipping of its own structure. The whole operation process is simple and convenient, and almost no auxiliary tools are required. Compared with other safety seats on the market, it has the advantages of wide range of use and easy operation.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
