Description

Technical Field

[0001] This application relates to the technical field of child seats, and particularly to an automotive child safety seat. Background Art

[0002] An automotive child safety seat, also known as a child restraint system CRS (Child Restraint System), is a seat designed for children of different ages (or weights), installed in a vehicle, and capable of effectively improving the safety of children during vehicle travel.

[0003] When the three-point seat belt originally installed in a vehicle is in use, it forms an oblique section for shoulder restraint and a horizontal section for abdominal restraint. The automotive child safety seat itself is also equipped with a five-point seat belt. When the child is young, the automotive child safety seat is fixed to the vehicle seat by the three-point vehicle seat belt, and then the child is fixed by the five-point seat belt on the safety seat, providing better protection. When the child grows older, the child sits on the safety seat, and the child and the safety seat are fixed to the vehicle seat together by the three-point vehicle seat belt.

[0004] Existing child safety seats usually have perforations provided in the diagonal direction of the backrest. When the child is young, the three-point vehicle seat belt passes through the perforations to fix the child safety seat.

[0005] When children of different ages take turns using the safety seat, the replacement of the fixing method of the safety seat is rather troublesome. Some parents directly fix the safety seat with the three-point vehicle seat belt and then restrain the younger child with the five-point seat belt. At this time, there is a large gap between the oblique section of the original three-point vehicle seat belt and the backrest of the safety seat, affecting the comfort of the child sitting on the safety seat. Therefore, improvement is needed. Utility Model Content

[0006] In order to make the fixing method of the child safety seat simple to operate and not affect the comfort of the child sitting on the automotive safety seat, this application provides an automotive child safety seat.

[0007] An automotive child safety seat provided by this application adopts the following technical solution:

[0008] An automotive child safety seat includes a safety seat body, and the safety seat body includes a base and a backrest installed on the base. Lower side plates are symmetrically arranged on the left and right sides of the base respectively. Each lower side plate is provided with two notch grooves, and the openings of the two notch grooves both face the front of the safety seat body. The two notch grooves are arranged at intervals in the up-down direction, and the bottom of one notch groove is closer to the backrest than the bottom of the other notch groove.

[0009] Preferably, the two notch grooves are a first notch groove and a second notch groove respectively. The first notch groove is close to the base, and the bottom of the second notch groove is closer to the backrest than the bottom of the first notch groove.

[0010] Preferably, the second notch groove includes a gentle channel and an inclined channel. The inclined channel is located at one end of the gentle channel close to the backrest, and the inclined channel communicates with the gentle channel. The inclined channel slopes gradually away from the base along the direction close to the backrest.

[0011] Preferably, the width dimension of the inclined channel is greater than the dimension of the gentle channel.

[0012] Preferably, the safety seat body further includes an arc-shaped head protection plate provided on the backrest to protect the head of the child sitting.

[0013] Preferably, an auxiliary accessory plate is installed on the arc-shaped head protection plate. A through notch groove for the diagonal section of the three-point seat belt to pass through is provided on the side of the auxiliary accessory plate facing away from the backrest, and the through notch groove extends in the direction close to the backrest.

[0014] Preferably, a limit hook capable of limiting the diagonal section of the three-point seat belt in the through notch groove is provided on the groove wall of the through notch groove close to the base side.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] When the child is small (height is 76 cm - 105 cm) and needs to use the five-point seat belt carried by the safety seat itself, the horizontal section of the vehicle-mounted three-point seat belt will pass through the first notch groove and fit more closely with the base, while the diagonal section of the three-point seat belt passes through the through notch groove and the second notch groove, and then fits more closely with the backrest, so that the entire vehicle-mounted seat belt fits more closely with the safety seat, and the child is more comfortable when sitting on the safety seat;

[0017] When the child is large (height is 100 cm - 150 cm), the five-point seat belt of the safety seat itself is no longer applicable. Therefore, the vehicle-mounted three-point seat belt is used to fix the child and the safety seat together. The horizontal section of the seat belt passes through the first notch groove, and the diagonal section of the seat belt passes through the through notch groove and the second notch groove, so that the path of the vehicle-mounted seat belt can be restricted, and the vehicle-mounted seat belt can fit more closely with the child. In addition, in a traffic accident, it can also prevent the vehicle-mounted seat belt from strangling the child's neck or abdomen;

[0018] The inclined channel extends in a direction away from the base, thereby determining the extension direction of the diagonal section of the seat belt, so that the diagonal section of the three-point seat belt can better fit the backrest after passing through the second notch groove;

[0019] After the diagonal section of the three-point seat belt passes through the threading notch groove, it can more closely fit the child sitting on the vehicle child safety seat to protect the child. In addition, the limiting hook can limit the diagonal section of the three-point seat belt within the threading notch groove. When using it next time, directly pull the diagonal section of the three-point seat belt at this position, and there is no need to move the diagonal section of the three-point seat belt into the threading notch groove again, thereby improving the convenience of using the seat belt.

[0028] The following will Figure 1-7 further describe the present application in detail with reference to the appended

[0029] An embodiment of the present application discloses a child safety seat for automobiles. Refer to Figure 1 With Figure 2 , the child safety seat for automobiles includes a safety seat body 1. The safety seat body 1 includes a base 11, a backrest 12, and an arc-shaped head protection plate 13. The base 11 is for a child to sit on. The backrest 12 is located at the rear side of the base 11. One side of the backrest 12 close to the base 11 is connected to the base 11 so as to form a certain angle to provide comfort for the sitting child; the other side of the backrest 12 extends upward away from the base 11 for the sitting child to lean on. The arc-shaped head protection plate 13 and the base 11 are on the same side of the backrest 12. The arc-shaped head protection plate 13 is located above the base 11 to protect the head of the sitting child, and the arc-shaped head protection plate 13 is installed on the backrest 12.

[0030] Furthermore, lower side plates 2 are symmetrically arranged on the left and right sides of the base 11 respectively, and upper side plates 3 are also symmetrically and integrally arranged on both sides of the backrest 12 respectively. The arrangement of the upper side plates 3 and the lower side plates 2, in cooperation with the base 11 and the backrest 12, will present a semi-enclosed state to the sitting child, thereby improving the protection effect on the sitting child.

[0031] Each lower side plate 2 is provided with two non-connected notch grooves. The two notch grooves are arranged at intervals in the up-down direction. The two notch grooves penetrate through the lower side plate 2 in the left-right direction in the thickness direction of the lower side plate 2, and the openings are located at the front end of the lower side plate 2, so that the notch openings of the notch grooves all face the front of the safety seat body 1. Furthermore, the notch grooves are of different depths, that is, the bottom of one notch groove is closer to the backrest 12 than the bottom of the other notch groove. The diagonal section 4 of the three-point seat belt is passed through and limited in the deeper notch groove, and the horizontal section 5 is passed through and limited in the shallower notch groove.

[0032] Refer to Figure 2 With Figure 3 , the lower side plate 2 and the base 11 are integrally formed. The above two notch grooves are respectively a first notch groove 21 and a second notch groove 22. Specifically, the one located below and with a shallower notch groove depth is defined as the first notch groove 21, and the one located above and with a deeper notch groove depth is the second notch groove 22.

[0033] Refer to Figure 3 With Figure 4 , as can be seen from the above, the second notch groove 22 is located above the first notch groove 21. When the safety seat is fixed in a three-point manner by an automobile seat belt, the horizontal section 5 of the three-point seat belt passes through the first notch groove 21, and the diagonal section 4 of the three-point seat belt passes through the second notch groove 22.

[0034] Since the depth of the second notch groove 22 is greater than that of the first notch groove 21, that is, the length of the second notch groove 22 extending towards the backrest 12 is greater than that of the first notch groove 21 extending towards the backrest 12, the diagonal section 4 of the three-point seat belt can fit more closely with the backrest 12 after passing through and being fixed by the second notch groove 22.

[0035] Refer to Figure 3 With Figure 4 , specifically, the second notch groove 22 includes a lower side wall 2201, a groove bottom surface 2202, and an upper side wall. The upper side wall is successively arranged as a third wall 2205, a second wall 2204, and a first wall 2203 from the opening of the second notch groove 22 towards the backrest 12. One end of the groove bottom surface 2202 is connected to one end of the first wall 2203 close to the backrest 12, and the other end of the groove bottom surface 2202 is connected to one end of the lower side wall 2201 close to the backrest 12. The upper end of the second wall 2204 and the upper end of the groove bottom surface 2202 are inclined from the front side to the rear side and are both inclined at an obtuse angle to the horizontal plane, so that an inclined channel 222 with a cross-section similar to a parallelogram accommodating space is formed between the second wall 2204, the first wall 2203, the groove bottom surface 2202, and the lower side wall 2201. A horizontal gentle channel 221 is formed between the third wall 2205 and the lower side wall 2201. An opening is provided at the connection between the second wall 2204 and the lower side wall 2201 so that the inclined channel 222 is connected to the gentle channel 221. It can be seen that the second notch groove 22 is composed of the connection of the inclined channel 222 and the gentle channel 221. Under the action of the inclined arrangement of the groove bottom surface 2202, the diagonal section 4 of the three-point seat belt can extend better along the direction of the inclined channel 222, and thus fit more closely with the backrest 12.

[0036] The distance between the first wall 2203 and the lower side wall 2201 is greater than the distance between the third wall 2205 and the lower side wall 2201, so that the width dimension of the inclined channel 222 is greater than the width dimension of the gentle channel 221, and thus it is more convenient for the diagonal section 4 of the seat belt to adjust its position or deployment state in the inclined channel 222. In addition, it also makes the diagonal section 4 of the three-point seat belt not easy to slide out of the inclined channel 222 during use, so as to improve the stability of the diagonal section 4 of the three-point seat belt fitting with the backrest 12 during use.

[0037] In addition, the adjacent two walls of the third wall 2205, the second wall 2204, the first wall 2203, the groove bottom surface 2202, and the lower side wall 2201 are connected by arc surfaces, so that the seat belt moves more smoothly in the second notch groove 22.

[0038] Refer to Figure 3 With Figure 5, the cross-section of the arc-shaped head protection plate 13 in the horizontal direction is C-shaped, and the top of the arc-shaped head protection plate 13 abuts against and is connected to the backrest 12. Since the lower side plates 2 are symmetrically arranged on the left and right sides of the base 11, auxiliary fitting plates 14 through which the diagonal sections 4 of the three-point seat belt pass and are limited are installed below the left and right sides of the arc-shaped head protection plate 13. The two auxiliary fitting plates 14 are symmetrically arranged and have the same structure. Therefore, the structure of one auxiliary fitting plate 14 will be described as an example below.

[0039] Referring to Figure 3 and Figure 5 , the auxiliary fitting plate 14 is installed on the arc-shaped head protection plate 13 by bolts. A through-notch groove 141 is formed on the side of the auxiliary fitting plate 14 facing away from the backrest 12. The through-notch groove 141 extends in the direction close to the backrest 12 and penetrates the auxiliary fitting plate 14 along the thickness direction of the auxiliary fitting plate 14. The diagonal section 4 of the three-point seat belt can enter and pass through the through-notch groove 141. Under the action of the through-notch groove 141, the diagonal section 4 of the three-point seat belt can fit more closely with the backrest 12 or the upper body of the child sitting. In another embodiment, an opening groove through which the diagonal section 4 of the three-point seat belt passes can be directly formed on the arc-shaped head protection plate 13.

[0040] Referring to Figure 3 and Figure 5 , a limiting hook 142 is integrally formed on the groove wall of the through-notch groove 141 close to the base 11 side. The limiting hook 142 is located at the notch of the through-notch groove 141. After the diagonal section 4 of the three-point seat belt passes through the through-notch groove 141, it is not easy to break away from the through-notch groove 141 under the action of the limiting hook 142. The limiting hook 142 includes a vertical portion 1421 and a horizontal portion 1422. The vertical portion 1421 extends away from the base 11 and close to the groove wall on the side of the through-notch groove 141 facing away from the base 11. There is a gap for the diagonal section 4 of the three-point seat belt to pass through between the vertical portion 1421 and the groove wall on the side of the through-notch groove 141 facing away from the base 11. The horizontal portion 1422 is located at the end of the vertical portion 1421 facing away from the base 11. The horizontal portion 1422 extends in the direction close to the backrest 12 along the extension direction of the through-notch groove 141. There is also a gap for the diagonal section 4 of the three-point seat belt to pass through between the horizontal portion 1422 and the groove wall on the side of the through-notch groove 141 facing away from the base 11. In addition, there is a certain gap between the end of the horizontal portion 1422 away from the vertical portion 1421 and the bottom of the through-notch groove 141. Thus, when the diagonal section 4 of the three-point seat belt is located between the horizontal portion 1422 and the groove wall of the through-notch groove 141 close to the base 11 side, it can be limited.

[0041] The usage method of the embodiment of the present application, referring toFigure 6 As shown, when a younger child uses a child safety seat, the child is fixed using the five-point seat belt carried by the child safety seat itself. Then, the upper part of the diagonal section 4 of the three-point seat belt is limited within the threading notch groove 141, the lower part of the diagonal section 4 is limited within the second notch groove 22, the transverse section 5 of the three-point seat belt is limited within the first notch groove 21, and the transverse section 5 of the vehicle-mounted seat belt will pass through the first notch groove 21 and fit more closely with the base 11. The diagonal section 4 of the three-point seat belt can pass through the threading notch groove 141 and the second notch groove 22, and thus fit more closely with the backrest 12. As a result, the entire vehicle-mounted three-point seat belt fits more closely with the child safety seat, and the child will be more comfortable when sitting on the child safety seat.

[0042] Referring to Figure 7 As shown, when the child is older, the five-point seat belt of the child safety seat itself is no longer applicable. Therefore, the vehicle-mounted three-point seat belt is used to fix the child and the child safety seat together. When an older child uses it, the upper part of the diagonal section 4 of the three-point seat belt is limited within the threading notch groove 141, the lower part of the diagonal section 4 of the three-point seat belt is limited within the second notch groove 22 and is in close contact with the second groove wall 2204 and the groove bottom surface 2202 within the second notch groove 22, and the transverse section 5 of the three-point seat belt is limited within the first notch groove 21, so that the path of the vehicle-mounted seat belt can be restricted, and the vehicle-mounted seat belt can fit more closely with the child. In addition, in a traffic accident, it can also prevent the vehicle-mounted seat belt from strangling the child's neck or abdomen.

[0043] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
