Description

A control mechanism for a multifunctional seat adjustment mechanism and a child safety seat thereof Technical Field

[0001] The present invention relates to the technical field of child safety seats, and in particular to a control mechanism of a multifunctional seat adjustment mechanism and a child safety seat thereof. Background Art

[0002] Child safety seats are specifically designed for children. With the development of society and the improvement of people's living standards, their use in families has become increasingly common. Their primary function is to protect children while in a vehicle, preventing or minimizing injuries from collisions or sudden braking. However, traditional child safety seats are often bulky, making them difficult to carry and store, especially in smaller vehicles where storage space is limited. Furthermore, traditional child safety seats are cumbersome to use, requiring repeated adjustments and fastenings, which not only increases the difficulty but also the time required.

[0003] There are also child safety seats with the functions of rotation and angle adjustment. For example, the invention patent with application number 201710442015.7, entitled "Child Safety Seat", discloses a child safety seat, a support base, which can be placed on a car seat, the support base comprising a fixed portion and a support portion, the fixed portion and the support portion being connected; a rotating platform; and a child seat, wherein the child seat, the rotating platform and the support portion can move synchronously relative to the fixed portion, and the child seat and the rotating platform can rotate synchronously between multiple positions as a seat unit. However, when in use, the tilt adjustment lock and the seat rotation lock need to be controlled separately by a release mechanism and a release member, that is, two different mechanisms are required to control the opening and closing of the tilt adjustment lock and the seat rotation lock, thereby controlling the angle adjustment and rotation of the seat respectively. The structure is complex, the cost is high, and the matching precision requirements between the components are high, which increases the manufacturing cost during the production process. In addition, the operation steps are very cumbersome and inconvenient to use. In addition, due to the relatively small space in the vehicle, it is very difficult for parents to secure their children in the car seat or to take them out of the car seat. Existing safety seats generally do not have the function of sliding the seat while it is rotated, and another release member is required to control the sliding, which is complicated to operate and not easy to use.
