Description

Technical Field

[0001] This utility model relates to the field of child car seats, and in particular to an infant car seat safety belt positioning structure and an infant car seat. Background Technology

[0002] A child car seat is a product specifically designed for infants and toddlers, installed in a car to facilitate their movement. As an auxiliary seat, it also functions as a collision protection device. In the event of a car collision or sudden deceleration, it can reduce the impact force on the child and restrict their body movement, thereby mitigating injury.

[0003] When in use, the infant is placed inside the seat and secured by the seatbelt buckle to achieve the aforementioned protection. For younger infants, the seatbelt is typically unbuckled, especially the shoulder strap, to allow the infant's arms to pass through. However, because younger infants are often uncontrollable and frequently move their arms when being placed in the seat, the seatbelt often pushes back against the seat back. Parents usually need to pull the seatbelt back up and then loop it around the infant's arm to buckle it again. This makes placing the infant more cumbersome and occurs frequently in daily use, often causing parents more frustration and affecting their experience with the product. Utility Model Content

[0004] The purpose of this invention is to provide a positioning structure for an infant car seat safety belt that can maintain the space for the safety belt to be stretched out and prevent the safety belt from deforming during the process of infants and young children putting it on, making it easier to use.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] An infant car seat safety belt positioning structure includes a mounting base disposed on a car seat body, a first support member and a second support member disposed on the mounting base, a limiting component and an unlocking component disposed on the mounting base;

[0007] The first and second support members cooperate with the seat belts on both sides respectively. The first and second support members can move relative to the mounting base to switch to the open position. When in the open position, the first and second support members jointly support the seat belts on both sides, so that the seat belts on both sides arch and maintain a through space between them and the back of the car seat body. The limiting component is used to limit the first and second support members to remain in the open position. After the unlocking component unlocks the limiting component, the first and second support members can be disengaged from the open position.

[0008] As described above, in an infant car seat safety belt positioning structure, the first support member and the second support member are rotatably mounted on the mounting base, and when in the extended position, the first support member and the second support member are away from the back of the car seat body to form an outwardly extending posture.

[0009] Furthermore, after the limiting component is unlocked, the first and second support members can rotate toward the back of the car seat body to move closer to the back and switch to the usage position.

[0010] As described above, in an infant car seat safety belt positioning structure, the limiting component can limit the first support member and the second support member to the use position.

[0011] As described above, in a baby car seat safety belt positioning structure, the first support member includes a first rotating seat and a first support rod disposed on the first rotating seat, wherein the first support rod is an elastic bendable rod.

[0012] When the first support member is in the open position, the limiting component is located under the first rotating seat to support and limit the rotation of the first rotating seat toward the use position.

[0013] As described above, in an infant car seat safety belt positioning structure, the limiting component includes a first limiting member and a second limiting member rotatably disposed on the mounting base. The first limiting member is located on one side of a first support member, and the second limiting member is located on one side of a second support member. The unlocking component is used to drive the first limiting member and the second limiting member to rotate away from the mounting base.

[0014] As described above, in a baby car seat safety belt positioning structure, the first limiting member is provided with a limiting part, the upper side of the limiting part has a limiting recess that is adapted to the outer peripheral surface of the first rotating seat, and the side of the limiting part facing the mounting seat also has a clamping position, the clamping position being used to accommodate the first rotating seat in the use position.

[0015] In the infant car seat safety belt positioning structure described above, the upper side of the first limiting member and the second limiting member also has a linkage part, and the unlocking component cooperates with the linkage part to drive the first limiting member and the second limiting member to rotate.

[0016] As described above, in an infant car seat safety belt positioning structure, the unlocking component includes an unlocking knob and a linkage unlocking component connected to the unlocking knob;

[0017] The linkage unlocking component has push-up portions on both sides that are opposite to the linkage part. The unlocking knob can drive the linkage unlocking component to move relative to the mounting base, and push the linkage part through the push-up portions to make the first limiting component and the second limiting component rotate.

[0018] In the infant car seat safety belt positioning structure described above, the unlocking knob is hinged to the linkage unlocking member. The unlocking knob has a push protrusion. When the unlocking knob is rotated upward along the hinge, the push protrusion abuts against the mounting base and forces the linkage unlocking member to move forward with the unlocking knob.

[0019] This utility model also provides an infant car seat, including a car seat body, wherein the car seat body is provided with the above-mentioned infant car seat safety belt positioning structure.

[0020] In summary, the advantages of this utility model over the prior art are:

[0021] This utility model provides an infant car seat safety belt positioning structure, which, by adding a first support member and a second support member, can cooperate with the safety belt on the child car seat body to support the flexible safety belt. Especially when it is in the open position, the safety belt is opened and arched at the shoulder strap position, and maintains a passage space relative to the arched back of the seat body. In this way, even if the opened safety belt is pressed by the body or arm during the placement of the infant, the passage space is still maintained under the action of the first support member and the second support member, making the placement operation simpler and easier.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1 to 12 This utility model provides an infant car seat safety belt positioning structure, including a mounting seat 1 on the car seat body 9, a first support member 21 and a second support member 22 on the mounting seat 1, a limiting component 3 and an unlocking component 4 on the mounting seat 1; the positioning structure can be a single component and can be installed on an infant car seat.

[0037] Specifically, the first support member 21 and the second support member 22 cooperate with the side seat belts 91 and 92, respectively. In infant car seats, the seat belts generally run from above the infant's shoulders down to the seat belt buckle on both sides to secure the infant in the seat. Therefore, there are generally two sections of the seat belt. This solution uses the left seat belt 91 and the right seat belt 92 as an example. Therefore, the first support member 21 and the second support member 22 are used to support both sections of the seat belt simultaneously. In application, for comfort, shoulder pads 99 are generally added at the shoulder position of the seat belt (e.g., ...). Figure 1 and Figure 2 As shown by the dotted line, the shoulder pad 99 directly covers the seat belt to form a soft padding layer, thereby avoiding the discomfort caused to infants and young children when the seat belt is tightened. The first support member 21 and the second support member 22 of this solution can be directly used with the shoulder pad 99 and can be inserted into the shoulder pad 99 to achieve the adaptation to the seat belt.

[0038] In this design, the first support member 21 and the second support member 22 are movable relative to the mounting base 1 to switch to the extended position. When in the extended position, the first support member 21 and the second support member 22 jointly support the seat belts 91 and 92 on both sides, causing the seat belts 91 and 92 to arch and maintain a through-space 901 between them and the back of the car seat body. The limiting component 3 is used to limit the first support member 21 and the second support member 22 to remain in the extended position. By adding the first support member and the second support member, it can cooperate with the seat belt on the child car seat body to support the flexible seat belt. Especially when it is in the extended position, the seat belt is arched at the shoulder strap position and maintains a through-space relative to the back of the seat body. In this way, even if the extended seat belt is pressed by the body or arm during the placement of the infant, the through-space is still maintained under the action of the first support member and the second support member, making the placement operation simpler and easier.

[0039] Furthermore, the limiting component 3 limits the first support member 21 and the second support member 22, effectively maintaining their extended posture. After the unlocking component 4 unlocks the limiting component 3, the first support member 21 and the second support member 22 can disengage from their extended position. This allows the seat belt to return to its normal operating posture, providing a certain degree of restraint and locking effect for infants and young children inside the seat.

[0040] As listed above, the first support member 21 and the second support member 22 can be movably mounted on the mounting base 1 to switch between different postures. They can be switched by simple sliding or rotation. In a preferred embodiment of this utility model, the first support member 21 and the second support member 22 are rotatably mounted on the mounting base 1. When in the open position, the first support member 21 and the second support member 22 are away from the back of the car seat body 9 to form an outward extending posture. Moreover, when in the open position, combined with their insertion into the shoulder pad, it is equivalent to being supported from the upper side of the seat belt, so that the seat belt always maintains the posture of being opened from the shoulder position to form a insertion space.

[0041] In this embodiment of the invention, after the limiting component 3 is unlocked, the first support member 21 and the second support member 22 can rotate toward the back of the car seat body 9 to switch to the use position. In use, simply rotating the support member to be close to the backrest cancels the support and allows it to be placed close to the infant with the seatbelt, without affecting the limiting performance after the seatbelt is tightened.

[0042] Of course, to prevent the first support member 21 and the second support member 22 from actually stretching the seat belt and causing it to lose its proper tightening effect when in use, the limiting component 3 can limit the first support member 21 and the second support member 22 to the use position. This prevents the first support member 21 and the second support member 22 from stretching open again after the seat belt is tightened.

[0043] In this embodiment of the invention, when the seatbelt is in use, the first support member 21 and the second support member 22 are actually pulled downwards. Therefore, when in the open position, the first support member 21 and the second support member 22 rotate upwards. However, the limiting component 3 restricts their rotation, preventing them from rotating downwards and keeping them in the open position. Of course, for greater convenience, an elastic reset component, such as a torsion spring, can be provided at the rotation position of the first support member 21 and the second support member 22, causing them to always tend to rotate towards the usage position. Thus, after the limiting component 3 is unlocked, the first support member 21 and the second support member 22 lose their restraint and automatically rotate in the opposite direction to the usage position, achieving the action of unlocking and tightening simultaneously.

[0044] In this design, the limiting component 3 includes a first limiting member 31 and a second limiting member 32 rotatably mounted on the mounting base 1. The first limiting member 31 is located on one side of the first support member 21, and the second limiting member 32 is located on one side of the second support member 22. The unlocking component 4 is used to drive the first limiting member 31 and the second limiting member 32 to rotate away from the mounting base 1. By using the rotatably mounted first limiting member 31 and the second limiting member 32 to limit the first support member 21 and the second support member 22 on both sides, unlocking is achieved simply by moving the first limiting member 31 and the second limiting member 32.

[0045] Specifically, the first limiting member 31 is provided with a limiting part 311. The upper side of the limiting part 311 has a limiting recess that is adapted to the outer peripheral surface of the first rotating seat 211. The limiting part 311 also has a clamping position on the side facing the mounting base 1. The clamping position is used to accommodate the first rotating seat 211 in the use position. The limiting part 311 disengages from the first support member 21 as the first limiting member 31 rotates, thereby unlocking the first support member 21. After unlocking, the first support member 21 rotates towards the use position under the action of an elastic element or external force. In this solution, the first limiting member 31 rotates outward when unlocked, and when the first support member 21 is in the use position, it also resets to press on the first support member 21, that is, the first support member 21 falls into the clamping position to play a certain limiting role. In the above embodiment, since the second limiting member 32 and the first limiting member 31 are basically symmetrically arranged, and their operating principle is the same as that of the first limiting member, the first limiting member 31 and the first support member 21 are used as examples for explanation.

[0046] When the first support member 21 is in the open position, the limiting component 3 is located below the first rotating seat 211 to support and limit the rotation of the first rotating seat 211 towards the use position. Of course, since the first limiting component 31 can be unlocked by rotating outwards, when the first support member 21 is in the use position, the user only needs to pull the seatbelt. The larger external force causes the first support member 21 to rotate outwards, automatically pressing against the first limiting component 31, causing the first limiting component 31 to rotate and move aside, making the operation simpler. Similarly, a reset structure can be provided on the first limiting component 31 to keep it rotating towards the limiting position. Thus, during the process of the first support member 21 rotating from the use position to the open position, the first limiting component 31 is first pushed up to rotate outwards. When it reaches the open position, the first limiting component 31 loses contact with the first support member 21 and automatically resets, thereby limiting its concave support to keep the first support member 21 in the open position. Preferably, in this solution, the reset structure can be implemented using a torsion spring 39 located at the hinge axis of the first limiting member 31 and the second limiting member 32.

[0047] In this utility model, the first support member 21 includes a first rotating seat 211 and a first support rod 212 disposed on the first rotating seat 211. The first support rod 212 is an elastic bendable rod, which is equivalent to adapting to the flexible seat belt posture. In this solution, the first support rod 212 is made of a spring, which can be bent downward along the axial direction.

[0048] In this embodiment of the invention, the unlocking component 4 includes an unlocking knob 41 and a linkage unlocking member 42 connected to the unlocking knob 41. The linkage unlocking member 42 has pushing portions 420 on both sides opposite to the linkage portion 33. The unlocking knob 41 can drive the linkage unlocking member 42 to translate relative to the mounting base 1, and the pushing portions 420 push the linkage portion 33 to rotate the first limiting member 31 and the second limiting member 32. Correspondingly, the upper side of the first limiting member 31 and the second limiting member 32 also has a linkage portion 33. The unlocking component 4 cooperates with the linkage portion 33 to drive the first limiting member 31 and the second limiting member 32 to rotate. Thus, unlocking is achieved by pulling the linkage unlocking member 42 with the unlocking knob 41, which in turn drives the first limiting member 31 and the second limiting member 32 to rotate.

[0049] Specifically, the mounting base 1 is provided with a connecting base 11, which is equipped with a limit and a slide rail structure for the linkage unlocking component 42. At the same time, a reset spring is provided between the connecting base 11 and the linkage unlocking component 42, so that the linkage unlocking component 42 automatically resets after unlocking.

[0050] Furthermore, the push-up portions 420 on both sides of the linkage unlocking component 42 in this solution have inclined guide surfaces. By contacting the linkage component 33 and moving forward, they gradually push the linkage component 33, so that the two limiting components can rotate outward to complete the unlocking.

[0051] Furthermore, this solution also achieves the unlocking operation by rotating the unlocking knob to pull the linkage unlocking component 42 forward. Specifically, the unlocking knob 41 is hinged to the linkage unlocking component 42. The unlocking knob 41 has a pushing protrusion 410. When the unlocking knob 41 is rotated upward along the hinge, the pushing protrusion 410 abuts against the mounting base 1, forcing the linkage unlocking component 42 to move forward with the unlocking knob 41. Since the unlocking knob 41 and the linkage unlocking component 42 are connected as a single component, the unlocking knob 41 can move relative to the mounting base 1 or the connecting base 11 with the linkage unlocking component 42. However, through clever design, this solution eliminates the need to directly pull the unlocking knob 41 during use. By rotating the unlocking knob 41 upward, the pushing protrusion 410 on it can abut against the mounting base 1, essentially becoming a rocker structure. During continued rotation, the abutment position drives the linkage unlocking component 42 to move forward, thus achieving the aforementioned unlocking.

[0052] This utility model also provides an infant car seat, including a car seat body 9, wherein the car seat body 9 has the aforementioned infant car seat safety belt positioning structure.

[0053] This utility model provides an infant car seat safety belt positioning structure, which, by adding a first support member and a second support member, can cooperate with the safety belt on the child car seat body to support the flexible safety belt. Especially when it is in the open position, the safety belt is opened and arched at the shoulder strap position, and maintains a passage space relative to the arched back of the seat body. In this way, even if the opened safety belt is pressed by the body or arm during the placement of the infant, the passage space is still maintained under the action of the first support member and the second support member, making the placement operation simpler and easier.

[0054] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
