DETAILED DESCRIPTION

[0042] The technical solutions of the present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0043] Embodiment 1

[0044] As Figures 1-4 , Figures 6-9As shown, the child safety seat comprises a seat body, a safety belt assembly and an airbag assembly.

[0045] As shown in the drawings, Figures 1-4 , Figures 6-9 the seat body comprises a base 11, a seat 12 arranged on the base 11, a backrest 13 connected with or integrally arranged with the seat 12, and a headrest 14 arranged on the backrest 13. The headrest 14 can be fixedly arranged on the backrest 13, or can be arranged on the backrest 13 in a sliding manner, so that the height of the headrest 14 on the backrest 13 can be adjusted as needed.

[0046] The safety belt assembly is arranged on the seat body. In this embodiment, as shown in the drawings, Figure 1 the safety belt assembly comprises a shoulder belt 21, a waist belt 22, a connecting belt 23 and a central buckle. The central buckle comprises a buckle seat 24 and a buckle, the buckle seat is connected to the connecting belt 23, the buckle is connected to the shoulder belt 21 and the waist belt 22, and the buckle seat 24 is detachably connected with the buckle. The shoulder belt 21 and the waist belt 22 can be one belt, in which case they share one buckle. The shoulder belt 21 and the waist belt 22 can also be two independent belts, in which case the shoulder belt 21 and the waist belt 22 are each provided with a buckle for detachable connection with the buckle seat 23.

[0047] In other embodiments, the connecting belt 23 can also not be provided, and the buckle seat 24 is directly connected to the seat 12 or to the airbag assembly.

[0048] The safety belt assembly has a tensioned state and a loosened state. When a child is seated on the seat body, the buckle is connected to the buckle seat 23, so that the safety belt assembly is in the tensioned state, thereby effectively restraining the child to provide safety protection for the child, as shown in the drawings. Figures 1-4 , Figures 6-9 .

[0049] As shown in the drawings, Figures 10-18 the airbag assembly comprises an airbag seat 31, an airbag 32, a gas generating device 33, a covering body 34 and a sheath.

[0050] The airbag 32 has a storage state and an inflated state. The gas generating device 33 is used to inflate the airbag 32, and the airbag 32 has an air inlet that is in communication with the gas generating device 33.

[0051] The airbag seat 31 has a receiving cavity for placing all or part of the gas generating device 33 and the airbag 32 in the storage state. The top of the airbag seat 31 is provided with a release port 3114 that is in communication with the receiving cavity, and the airbag 32 inflates and expands out of the receiving cavity through the release port 3114.

[0052] When the air bag 32 is in the inflated state, the air bag 32 has a reverse "C" shape in cross section along the up-down direction, one end of the reverse "C" shape of the air bag 32 is the air inlet of the air bag 32, the other end of the reverse "C" shape of the air bag 32 is fixedly connected to the rear of the air bag seat 31, and the opening of the reverse "C" shape of the air bag 32 faces the seat body, as shown in Figs. 1 and 2. Figure 9 and Figure 14 When the car collides and the child's head moves forward, the middle part of the reverse "C" shaped air bag 32 can provide good support to the child's head, reduce the impact force, and improve safety.

[0053] When the car is running normally, the child is seated on the seat body, and the safety belt assembly is in the tension state to bind the child. The air bag 32 is in the storage state and is accommodated in the accommodating cavity of the air bag seat 31, and the shoulder belt 21 is pressed on the side of the air bag seat 31 away from the backrest 13.

[0054] When the car collides, the gas generating device 33 inflates the air bag 32, so that the air bag 32 expands and rushes out of the release port 3114 to the outside of the accommodating cavity. When the air bag 32 expands, the shoulder belt 21 is pushed to move to the left side or the right side of the air bag seat 31, so that the part of the shoulder belt 21 pressed on the air bag seat 31 is separated from the air bag seat 31.

[0055] In this way, at the moment when the air bag 32 starts to inflate and expand, due to the cooperation of the shoulder belt 21 and the air bag seat 31, the air bag seat 31 can be prevented from moving forward with the air bag 32, and the air bag 32 after inflation can maintain a proper distance from the child's body to support the child's head. During the inflation of the air bag 32, the shoulder belt 21 can be separated from the air bag seat 31, so that the shoulder belt 21 does not affect the inflation of the air bag 32, and the air bag 32 can expand in the set shape to support and protect the child after inflation.

[0056] Specifically, the side of the air bag seat 31 away from the backrest 13 is provided with a guide surface 3111a, which is inclined from front to back towards the left side of the air bag seat 31 or the right side of the air bag seat 31 as a whole. When the safety belt assembly is in the tension state and the air bag 32 is in the storage state, the shoulder belt 21 is pressed on the guide surface 3111a. When the air bag 32 is in the inflated state, the shoulder belt 21 moves along the guide surface 3111a to the left side or the right side of the air bag seat 31 to separate from the guide surface 3111a.

[0057] In this embodiment, two shoulder straps 21 and two waist straps 22 are provided, and the shoulder straps 21 and the waist straps 22 are arranged on the left and right sides of the seat body one by one, and the two shoulder straps 21 are located on the left and right sides of the airbag seat 31. When the safety belt assembly is in the tension state and the airbag 32 is in the storage state, the two shoulder straps 21 are respectively arranged on the left and right sides of the side of the airbag seat 31 away from the backrest 13. When the airbag 32 is inflated, the airbag 32 extends to the left and right sides of the child safety seat, and the left and right sides of the airbag 32 abut against the corresponding shoulder strap 21, so that the two shoulder straps 21 move outward of the airbag seat 31, and then slide off the airbag seat 31.

[0058] Correspondingly, the guide surfaces 3111a are arranged on the left and right sides of the side of the airbag seat 31 away from the backrest 13, and the distance between the left and right guide surfaces 3111a gradually increases from front to back. When the safety belt assembly is in the tension state and the airbag 32 is in the storage state, the two shoulder straps 21 are respectively arranged on the corresponding guide surface 3111a. When the airbag 32 is in the inflated state, the two shoulder straps 21 are separated from the guide surface 3111a.

[0059] The accommodating cavity of the airbag seat 31 has a plurality of side walls arranged around, which specifically include a front side wall 3112, a rear side wall 3113 and a connecting side wall 3111. The front side wall 3112 is located in front of the accommodating cavity, and can be a plane, an arc surface or a combination of a plurality of surfaces. The rear side wall 3113 is located at the rear of the accommodating cavity, i.e. towards the side of the child's body, and is a plane, so as to be closely arranged in front of the child's chest, thereby improving comfort. The front and rear ends of the left and right connecting side walls 3111 are respectively connected with the front side wall 3112 and the rear side wall 3113, i.e. the left and right connecting side walls 3111 form the left and right side walls of the accommodating cavity. The size of the front side wall 3112 in the left-right direction is smaller than that of the rear side wall 3113 in the left-right direction, so that the left and right connecting side walls 3111 are arranged obliquely from front to back, and the distance between the left and right connecting side walls 3111 gradually increases from front to back. The guide surface 311 is arranged on the side of the connecting side wall 3111 away from the accommodating cavity.

[0060] In this embodiment, as shown in Figure 6 and Figure 15 , the left and right connecting side walls 3111 are curved as a whole and arch towards the accommodating cavity, and the guide surface 3111a is the front surface of the connecting side wall 3111, which is correspondingly in the form of a curved surface. When the safety belt assembly is in the tension state and the airbag 32 is in the storage state, the two shoulder straps 21 are arranged on the front surface of the corresponding connecting side wall 3111. This arrangement can make the shoulder straps 21 better arranged on the connecting side wall 3111 when the airbag 32 is not inflated, and facilitate the shoulder straps 21 to slide off the connecting side wall 3111 during the inflation of the airbag 32.

[0061] In other embodiments, the upper of each side connecting side wall 3111 is provided with a groove recessed rearward from the front surface of the connecting side wall 3111, the groove extending through the upper and lower end surfaces of the connecting side wall 3111, and the groove bottom forming a guide surface 3111a. When the safety belt assembly is in the tensioned state and the airbag 32 is in the stowed state, the shoulder belts 21 on both sides are pressed into the corresponding groove. The provision of the groove on the connecting side wall 3111 allows the shoulder belts 21 to be better pressed against the connecting side wall 3111 when the airbag 32 is not inflated.

[0062] The end of the groove close to the outer side and the front surface of the connecting side wall 3111 are provided with a transition section, which is a slope extending from inside to outside and from rear to front. The provision of the transition section facilitates the shoulder belts 21 to be released from the groove during the inflation of the airbag 32.

[0063] The groove bottom can be a flat surface. Alternatively, the groove bottom can also be a curved surface recessed toward the accommodation cavity.

[0064] Alternatively, the front surface of each side connecting side wall 3111 is a smooth and coherent flat surface, and the front surface of the connecting side wall 3111 forms the guide surface 3111a. When the safety belt assembly is in the tensioned state and the airbag 32 is in the stowed state, the shoulder belts 21 on both sides are pressed against the front surface of the corresponding connecting side wall 3111. In this way, the shoulder belts 21 are more easily released from the connecting side wall 3111 during the inflation of the airbag 32.

[0065] In this embodiment, the airbag seat 31 includes a housing 311 and a support 312 arranged at the bottom of the housing 311 and supporting the housing 311, and the accommodation cavity is arranged in the housing 311, and the corresponding guide surface 3111a is also arranged in the housing 311.

[0066] The airbag seat 31 also has a support portion 313 arranged on the housing 311 and along the edge of the release port 3114, which is used to support the airbag 32 in the inflated state, so that the position of the airbag 32 is stable, thereby avoiding the airbag 32 from shaking and moving downward, and allowing the airbag 32 to better protect the head, chest and other parts of the child, and improving the protection effect and safety performance of the child safety seat during use.

[0067] Specifically, the support portion 313 is arranged on the side wall of the accommodating cavity of the airbag seat 31, and at least the top of the support portion 313 forms a support surface 313a for supporting the airbag 32 in the inflated state. The support surface 313a extends in the thickness direction of the side wall and has a length greater than the thickness of the side wall where the support portion 313 is arranged. Preferably, the support surface 313a extends in the thickness direction of the side wall by at least twice the thickness of the side wall. The support surface 313a is located at a position close to the air inlet of the airbag 32.

[0068] The side wall has an inner wall surface surrounding the accommodating cavity and an outer wall surface arranged opposite the inner wall surface. The support surface 313a extends outward from the inner wall surface in the thickness direction of the side wall.

[0069] In a specific embodiment, the side wall has a portion at the top forming the support portion 313, and the top surface of the support portion 313 forms the support surface 313a.

[0070] In another specific embodiment, the support portion 313 is arranged on the outer wall surface of the side wall and close to the top of the side wall. The top surface of the support portion 313 is connected to the top surface of the side wall, so that the top surface of the support portion 313 and the top surface of the side wall together form the support surface 313a.

[0071] In the above two embodiments, the support portion 313 gradually increases in cross-sectional size in a direction away from the side wall, i.e., the cross-section of the support portion 313 in the up-down direction forms a triangular structure.

[0072] The side wall as a whole can be plate-shaped, and the support portion 313 is also plate-shaped. The extension direction of the support portion 313 is perpendicular to the extension direction of the side wall, i.e., the support portion 313 and the side wall where it is arranged form an inverted L-shaped structure, as shown in Figure 12 , Figure 14 and Figure 15 .

[0073] The support surface 313a can be a flat surface or an upwardly convex curved surface.

[0074] In this embodiment, the front side wall 3112 and the rear side wall 3113 are both provided with the support portion 313. After the support portion 313 is arranged on the front side wall 3112, when the airbag 32 is inflated and expanded, the airbag 32 can be prevented from moving forward and downward by the support portion 313, so that the airbag 32 can maintain a proper distance from the child's body after inflation and expansion, thereby enabling the airbag 32 to better protect the child's head, chest and other parts in all directions.

[0075] When the airbag 32 is in the storage state, the cover body 34 covers the release port 3114 and the support surface 313a, as shown in Figure 4 and Figure 12The release port 3114 can be blocked by the cover 34, and the support surface 313a can be protected from being damaged by the support surface 313a. When the air bag 32 is inflated, the air bag 32 breaks the cover 34, and the cover 34 is separated from the release port 3114 and the support surface 313a, as shown in Figure 9 and Figure 14 as shown.

[0076] A cover is arranged outside the air bag seat 31. The cover is generally a cloth cover, so as to improve the comfort of the child safety seat when used. As shown in Figure 15 and Figure 18 The air bag seat 31 is further provided with a hook 314 for fixing the cover. The hook 314 is arranged on the support part 313 and has a gap space between the side wall. The hook 314 includes a main body part and a hook part arranged at the lower end of the main body part. The main body part extends downward from the outer end of the support surface 313a, and the hook part extends or bends from the lower end of the hook to the side of the accommodating cavity.

[0077] When the safety belt assembly is in a tensioned state, the buckle seat 24 is located in front of the air bag seat 32, and the joint position of the shoulder belt 21 and the connecting belt 23, i.e., the joint position of the buckle seat 23 and the buckle, corresponds to the position of the support part 312 in the height direction of the air bag seat 31, as shown in Figures 1-9 Thus, when the car collides, the buckle seat 24 can also prevent the air bag seat 31 from moving forward, and the distance between the air bag 32 and the child after the air bag 32 is inflated can be prevented from being too far to support and protect the child.

[0078] In one embodiment, the buckle seat 24 and the support part 312 are independently arranged on the seat 12.

[0079] Preferably, both are arranged on the seat 12 in a relative movement manner. Thus, when the child enters or exits the child safety seat, both can move away from the seating space of the child safety seat, so as to facilitate the child to enter or exit.

[0080] The buckle seat 24 and the support part 312 can move relative to the seat 12 in the following manner: both are arranged on the seat 12 by rotating around a rigid rotating shaft extending in the left-right direction. Alternatively, the support part 312 is arranged on the seat 12 by rotating around a rigid rotating shaft extending in the left-right direction, and the buckle seat 24 is connected to the seat 12 by the connecting belt 23.

[0081] The connection between the buckle seat 24 and the seat 12 and the connection between the support part 312 and the seat 12 can coincide, as shown in 4 and Figure 5As shown, the support 312 is rotatably arranged on the seat 12 through a rotating shaft 4 extending in the left-right direction, the connecting belt 23 is sleeved on the rotating shaft 4, and the buckle seat 24 is connected to the connecting belt 23. The connection between the buckle seat 24 and the seat 12 and the connection between the support 312 and the seat 12 can also be arranged at different positions.

[0082] In another embodiment, the buckle seat 24 is arranged on the seat 12, and the support 312 is arranged on the buckle seat 24.

[0083] Preferably, the buckle seat 24 is arranged on the seat 12 in a relative movement manner, which is also convenient for the child to get in and out of the child safety seat.

[0084] The buckle seat 24 can be rotatably arranged on the seat 12 through a rigid rotating shaft extending in the left-right direction, or can be connected to the seat 12 through the connecting belt 24.

[0085] In another embodiment, the support 312 is arranged on the seat 12, and the buckle seat 24 is arranged on the support 312.

[0086] Preferably, the support 312 is arranged on the seat 12 in a relative movement manner, which is also convenient for the child to get in and out of the child safety seat.

[0087] The support 312 can be rotatably arranged on the seat 12 through a rigid rotating shaft extending in the left-right direction, or can be connected to the seat 12 through a soft webbing.
