[0002] A child car seat is a seat product designed specifically for infants and young children. It is installed in the car to facilitate infants and young children to ride in the car. As an auxiliary seat, it also has functions such as collision protection. In the event of a car collision or sudden deceleration, it can reduce the impact pressure on the child and limit the child's body movement, thereby reducing their injuries.
[0003] When in use, the infant is placed in the seat body and restrained in the seat body after the seat belt is buckled, so as to achieve the above protection purpose. When used by younger infants, the seat belt is usually pulled open, especially the shoulder belt part, to form a space for the infant's arms to pass through. However, since the behavior of younger infants is uncontrolled, their arms often move when they are held in the seat, causing the seat belt to be pressed back to the backrest of the seat. Parents usually need to pull up the seat belt again and then go around the baby's arms to complete the buckle, which makes the operation of placing the infant more cumbersome and often occurs in daily use, often causing more annoyance to parents and affecting their experience of using the product.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0036] See also Figures 1 to 12 The present invention provides a baby car seat safety belt positioning structure, comprising a mounting seat 1 arranged on a car seat body 9, a first support member 21 and a second support member 22 arranged on the mounting seat 1, a limiting component 3 and an unlocking component 4 arranged on the mounting seat 1; the positioning structure as a whole can be a component, which can be installed on the baby car seat for use.
[0037] Specifically, the first support member 21 and the second support member 22 cooperate with the safety belts 91 and 92 on both sides, respectively. In an infant car safety seat, the safety belt is generally fastened from the upper part of the infant's shoulders to the safety belt on both sides, thereby fixing the infant in the seat. Therefore, there are generally two sections of safety belts. This solution uses the left safety belt 91 and the right safety belt 92 as embodiments. Therefore, the first support member 21 and the second support member 22 are adapted to support the two sections of safety belts at the same time. In application, for the sake of comfort, a shoulder pad 99 (such as Figure 1 and Figure 2 As shown by the dotted line, the shoulder pad 99 is directly covered on the safety belt to form a cushion layer, thereby avoiding the discomfort caused by the infant being tightened by the safety belt. The first support member 21 and the second support member 22 of the present scheme can directly cooperate with the shoulder pad 99, and can be inserted into the shoulder pad 99 to achieve adaptation for use with the safety belt.
[0038] In the present solution, the first support member 21 and the second support member 22 can be moved relative to the mounting seat 1 to switch to the expanded position, and when in the expanded position, the first support member 21 and the second support member 22 jointly support the safety belts 91 and 92 on both sides, so that the safety belts 91 and 92 on both sides are arched and maintain a insertion space 901 between the backrest of the car seat body, and the limiting component 3 is used to limit the first support member 21 and the second support member to remain in the expanded position. By adding the first support member and the second support member, it can cooperate with the safety belt on the child car seat body to support the flexible safety belt, especially when it is in the expanded position, so that the safety belt, especially at the position of the shoulder belt, is expanded and arched, and maintains the insertion space relative to the arched backrest of the seat body. In this way, even if the stretched safety belt is pressed by the body or arm during the placement of the infant, the insertion space is still maintained under the action of the first support member and the second support, making the placement operation simpler and easier.
[0039] Furthermore, the first support member 21 and the second support member 22 are limited by the limiting assembly 3 so that they can effectively maintain the open position, and after the unlocking assembly 4 unlocks the limiting assembly 3, the first support member 21 and the second support member 22 can be separated from the open position, so that the safety belt can return to the normal use position, so as to play a certain role in limiting and locking the infant in the seat.
[0040] As in the scheme listed above, the first support member 21 and the second support member 22 can be movably arranged on the mounting seat 1 to correspond to the switching posture of use, which can adopt simple sliding switching or rotation switching. Preferably, in the embodiment of the present invention, the first support member 21 and the second support member 22 can be rotatably arranged on the mounting seat 1, and when in the expanded position, the first support member 21 and the second support member 22 are away from the backrest of the automobile seat body 9 to form an outward extending posture; and in the expanded position, combined with its insertion in the shoulder pad, it is equivalent to supporting from the upper side of the safety belt, so that the safety belt always maintains the posture of being expanded from the shoulder position to form a insertion space.
[0041] In the embodiment of the present invention, after the limiting assembly 3 is unlocked, the first support member 21 and the second support member 22 can be rotated toward the backrest of the car seat body 9 to switch to the use position close to the backrest. When in use, it only needs to be rotated close to the backrest, and the supporting state is cancelled, and the safety belt is close to the baby, which does not affect the limiting performance after the safety belt is fastened.
[0042] Of course, in order to prevent the first support member 21 and the second support member 22 from propping up the safety belt and causing it to lose its tightening effect when in use, the limiting assembly 3 can limit the first support member 21 and the second support member 22 to the use position to prevent the first support member 21 and the second support member 22 from being stretched out again after the safety belt is tightened.
[0043] In the embodiment of the present invention, when used in combination with a seat belt, the first support member 21 and the second support member 22 are actually tightened downward. Therefore, when in the expanded position, the first support member 21 and the second support member 22 rotate upward, and are restricted by the limiting component 3, so that the first support member 21 and the second support member 22 cannot rotate downward, thus remaining in the expanded position. Of course, for more convenient use, an elastic reset member, such as a torsion spring, can be arranged at the rotating positions of the first support member 21 and the second support member 22, so that it always tends to rotate towards the use position. In this way, after the limiting component 3 is unlocked, the first support member 21 and the second support member 22 are released from restraint and automatically rotate in the reverse direction towards the use position, and the action of tying up immediately after unlocking can be realized.
[0044] In this solution, the limiting component 3 includes a first limiting member 31 and a second limiting member 32 rotatably arranged 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. The rotatably arranged first limiting member 31 and second limiting member 32 are respectively used to limit the first support member 21 and the second support member 22 on both sides. When unlocking, only the first limiting member 31 and the second limiting member 32 need to be moved to unlock.
[0045] Specifically, the first limiting member 31 is provided with a limiting portion 311. The upper side of the limiting portion 311 has a limiting concave position adapted to the outer peripheral surface of the first rotating seat 211. The side of the limiting portion 311 facing the mounting base 1 also has a clamping position for accommodating the first rotating seat 211 in the use position. The limiting portion 311 rotates with the first limiting member 31 and disengages from the cooperation with the first support member 21, 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 member or an external force. When the first limiting member 31 of this solution is unlocked, it rotates outward. When the first support member 21 is in the use position, it also resets and presses 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 principles are the same as those of the first limiting member, the first limiting member 31 and the first support member 21 are taken as examples for illustration.
[0046] When the first support member 21 is in the deployed position, the limiting component 3 is located below the first swivel base 211 to support and limit the rotation of the first swivel base 211 in the direction of the use position. Of course, since the first limiting member 31 can be unlocked by rotating outward, when the first support member 21 is in the use position, the user only needs to pull up the safety belt. The relatively large external force causes the first support member 21 to rotate outward, which can automatically press against the first limiting member 31 to make the first limiting member 31 rotate to make way, making the operation simpler. Similarly, a reset structure can be provided on the first limiting member 31 to keep it rotating in the direction of the limiting position. In this way, during the process of the first support member 21 rotating from the use position to the deployed position, the first limiting member 31 is first lifted to make it rotate outward. When reaching the deployed position, the first limiting member 31 loses contact with the first support member 21 and automatically resets, so that its limiting concave position supports the first support member 21 to be limited in the deployed position. Preferably, in this solution, the reset structure can be realized by a torsion spring 39 provided at the hinge axis of the first limiting member 31 and the second limiting member 32.
[0047] In the solution of the present invention, the first support member 21 includes a first swivel base 211 and a first support rod 212 provided on the first swivel base 211. The first support rod 212 is an elastic and bendable rod, which is equivalent to adapting to the flexible posture of the safety belt. In this solution, the first support rod 212 is composed of a spring and can be bent downward along the axial direction.
[0048] In the embodiment of the present invention, the unlocking component 4 includes an unlocking knob 41 and a linkage unlocking member 42 connected to the unlocking knob 41; both sides of the linkage unlocking member 42 have a pushing portion 420 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 push the linkage portion 33 through the pushing portion 420 to make the first limiting member 31 and the second limiting member 32 rotate. Correspondingly, the upper sides of the first limiting member 31 and the second limiting member 32 also have 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. In this way, by pulling the linkage unlocking member 42 with the unlocking knob 41, and then driving the first limiting member 31 and the second limiting member 32 to rotate by the linkage unlocking member 42, the unlocking can be completed.
[0049] Specifically, a connecting seat 11 is provided on the mounting base 1, a sliding rail structure for limiting and the linkage unlocking member 42 is provided on the connecting seat 11, and a reset spring is provided between the connecting seat 11 and the linkage unlocking member 42, so that the linkage unlocking member 42 automatically resets after being unlocked.
[0050] Furthermore, the pushing portions 420 on both sides of the linkage unlocking member 42 in this solution have inclined guiding surfaces. By touching the linkage portion 33 and gradually pushing the linkage portion 33 during the forward movement, the two limiting members can rotate outward to complete the unlocking.
[0051] In addition, the present solution also realizes the unlocking operation of pulling the linkage unlocking member 42 to move forward by rotating the unlocking knob. Specifically, the unlocking knob 41 is hinged on the linkage unlocking member 42, and the unlocking knob 41 has a push protrusion 410. When the unlocking knob 41 rotates upward along the hinge, the push protrusion 410 abuts against the mounting seat 1 and forces the linkage unlocking member 42 to move forward with the unlocking knob 41. Since the unlocking knob 41 and the linkage unlocking member 42 are connected as one component, that is, the unlocking knob 41 can move relative to the mounting seat 1 or the connecting seat 11 with the linkage unlocking member 42, and the present solution is cleverly designed. When in use, there is no need to directly pull the unlocking knob 41. By rotating the unlocking knob 41 upward, the push protrusion 410 thereon can abut against the mounting seat 1, which is equivalent to a seesaw structure. During the continued rotation, through the abutting position, the linkage unlocking member 42 is driven to move horizontally to achieve the above unlocking.
[0052] The present invention further provides a baby car seat, comprising a car seat body 9, wherein the car seat body 9 has the above-mentioned baby car seat safety belt positioning structure.
[0053] The present invention provides a baby car seat safety belt positioning structure, which can cooperate with the safety belt on the child car seat body by adding a first support member and a second support member, and is used to support the flexible safety belt, especially when it is in the extended position, so that the safety belt is extended and arched, especially at the position of the shoulder belt, and maintains a passing space relative to the arched backrest of the seat body. In this way, even if the extended safety belt is pressed by the body or arm during the placement of the infant, the passing 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 above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
