Description

Shoulder belt adjustment mechanism and child seat with the adjustment mechanism

technical field

The utility model relates to the technical field of seat adjustment mechanisms, in particular to a shoulder belt adjustment mechanism and a child seat with the adjustment mechanism.

Background technique

As we all know, there are many types of infant carriers on the market, such as high chairs for infants to sit at the dining table so that adults can take care of them nearby, or for infants to be strapped to the car. Children's car safety seats on the seat, and these products are mostly equipped with shoulder straps for the safety of young children, and the shoulder straps can be used to fix the infants sitting on them, so as to prevent infants and young children from being messed up. Move and bruise, fall.

However, the shoulder strap heights of existing seats are all adjusted through a row of mutually independent holes, and this method has two disadvantages: one, this adjustment method is cumbersome. When adjusting, first disassemble the shoulder straps, pull them out from the holes, insert them into the desired height holes, and then connect the upper and lower parts of the shoulder straps. In the adjustment process, it is usually necessary to separate the shoulder straps on the left and right sides. Adjustment, the synchronous adjustment of the left and right shoulder straps cannot be realized, and the operation is inconvenient. Especially for car safety seats, due to the limitation of the space of the car, the structure is relatively compact, and the connecting parts are relatively firm, so the adjustment is added invisibly. Difficulty, the operation is more inconvenient. Second, the adjustment distance is limited, and it is difficult to meet the needs of children's height comparison. Because this pattern of independent holes piercing the shoulder straps is made directly on the chair body, although the structure is simple, it has a great impact on the strength and safety of the safety chair. In order to ensure the strength and safety of the chair, often such holes The distance between them is very large, but the height of the human body is a little bit longer, so it is difficult to ensure the comfort of the chair.
