[0002] As more and more families own private cars, driving has become the preferred mode of travel for many car-owning families. At the same time, seat belts are an indispensable passenger restraint device in the passive safety of automobiles. When the car is in emergency braking or a collision accident occurs, it can effectively pull the passengers so that they can be restrained in the seat, avoiding the body from rushing forward or causing a secondary collision due to inertia, avoiding or reducing the injuries suffered by the passengers, and playing a role in protecting the passengers.

[0003] A child car safety seat is a seat designed for children of different ages and installed in a private car to effectively improve the safety of children in a car. Existing child car safety seats generally have a buffer device on the seat belt. The buffer device currently used includes a shoulder belt guard with a certain thickness and width directly set on the shoulder belt in the seat belt. The shoulder belt guard increases the thickness and width of the shoulder belt, so that the child's shoulders are buffered when the seat belt is under force. However, the existing sliding shoulder belt guard is easy to slide on the shoulder belt after being connected to the shoulder belt, and it is easy to slide off the child's shoulder, which is inconvenient to use. At the same time, the size of the protective pad is fixed and cannot be adjusted appropriately according to the size of the pressure. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model proposes: a safety belt assembly for a child car safety seat, including a belt body 1 and a protective pad assembly 2, the belt body 1 is arranged on the belt cover 201 of the protective pad assembly 2 in a through-type manner, ensuring that the protective pad assembly 2 is stably installed on the belt body 1, so that the two can be stably used together, reducing the pressure of the belt body 1 on the human body, and improving the comfort of using the safety belt, the notch 2015 opened on the belt cover 201 is provided with an elastic limiting plate 2012 that abuts against the belt body 1, and the elastic limiting plate 2012 is used to stably limit and fix the protective pad assembly 2 at a designated use position on the belt body 1, so as to prevent the protective pad assembly 2 from sliding arbitrarily on the belt body 1, and effectively protect the child's body, and the belt cover 201 and An elastic airbag 203 is arranged between the contact plate 202, forming a soft contact component between the two, so that when the contact plate 202 is squeezed, it can produce a certain displacement toward the belt cover 201, thereby effectively squeezing the movable guard plate 204, driving the movable guard plate 204 to slide and unfold smoothly toward the outside, thereby expanding the contact area between the protection pad and the human body, reducing the pressure on the human body, and ensuring comfortable use. In addition, a movable guard plate 204 is slidably arranged between the contact plate 202 and the belt cover 201. The movable guard plate 204 that can be slidably unfolded serves as an extension component during use, thereby increasing the contact area between the protection pad and the human body, reducing the pressure on the human body by the belt body 1 and the protection pad assembly 2 during use, and improving the comfort of use.

[0023] like Figure 2 and Figure 3As shown, in some embodiments, one end of the elastic limiting plate 2012 is fixedly connected to the slot 2015 opened on the belt sleeve 201, ensuring that the elastic limiting plate 2012 is stably placed on the belt sleeve 201, and contacts the belt body 1 during use, so that the belt sleeve 201 is limited and fixed at the designated use position on the belt body 1. The other end of the elastic limiting plate 2012 is a movable end and is integrally provided with a buckle, which is placed on the edge of the slot 2015 to facilitate fixing the movable end of the elastic limiting plate 2012 on the slot 2015, thereby stably and effectively limiting and fixing the belt body 1. The middle part of the elastic limiting plate 2012 is bent toward the belt threading groove 2011 opened in the belt sleeve 201 and contacts the surface of the belt body 1, ensuring that the belt body 1 is stably and effectively limited.

[0024] like Figure 1 and Figure 2 As shown, in some embodiments, both sides of the elastic airbag 203 are fixedly connected with an embedding block 2031, wherein the embedding block 2031 on one side is fixedly embedded in a first embedding groove 2013 opened on the belt sleeve 201, and the embedding block 2031 on the other side is fixedly embedded in a second embedding groove 2023 opened on the contact plate 202. The embedding block 2031 is used to stably connect the elastic airbag 203 between the belt sleeve 201 and the contact plate 202, so that the three can be stably used together. At the same time, the elastic airbag 203 forms a soft contact between the contact plate 202 and the belt sleeve 201, ensuring that when the contact plate 202 is squeezed, it can move toward the belt sleeve 201 together with the deformation of the elastic airbag 203, and then can exert effective squeezing and pushing on the movable guard plate 204.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the second slider 2041 provided on the movable guard plate 204 is slidably connected to the first slide groove 2014 opened on the belt cover 201, and the movable guard plate 204 slides against the belt cover 201 to ensure the stability of the movable guard plate 204 sliding between the belt cover 201 and the contact plate 202, so that during use, when the contact plate 202 applies pressure to the movable guard plate 204, the movable guard plate 204 slides and unfolds smoothly toward both sides, thereby expanding the contact area between the entire protective pad and the child's body, and reducing the pressure of the belt body 1 and the protective pad assembly 2 on the human body. The movable guard plate 204 is provided with a first sliding groove 2043 which is provided at a corresponding position on the contact plate 202, thereby improving the sliding stability between the two and preventing the movable guard plate 204 from falling off during the sliding process.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
