Abstract

A child safety seat includes a base; a rotatable seat above the base and having a rotation threshold angle; and a misuse prevention mechanism on the base and the rotatable seat and having a locked state and a released state. When the misuse prevention mechanism is in the locked state, the misuse prevention mechanism prevents the rotatable seat from rotating past the rotation threshold angle in a first direction and allows the rotatable seat to rotate past the rotation threshold angle in a second direction opposite to the first direction. When the misuse prevention mechanism is in the released state, the misuse prevention mechanism allows the rotatable seat to rotate past the rotation threshold angle in both the first direction and the second direction.

Description

CROSS REFERENCE TO RELATED APPLICATIONS This application is a continuation application of U.S. application Ser. No. 18/255,700, filed Jun. 2, 2023, which is a U.S. National Stage of International Application No PCT/EP2021/084218, filed on Dec. 3, 2021, which claims priority to Chinese Patent Application No. 202011412522.4, entitled “CHILD SAFETY SEAT”, filed on Dec. 4, 2020. The disclosures of the aforementioned applications are incorporated herein by reference in their entireties. TECHNICAL FIELD The present disclosure relates to a child safety seat. BACKGROUND A child safety seat is a seat specially designed for children. By assembling the child safety seat in a car, a child may ride in the car on the child safety seat. The child safety seat is used to restrain the child to protect the child's safety. An ISOFIX interface is an international standard (ISO 13216) for attachment points for child safety seats in cars. The existing child safety seat usually includes a base and a seat arranged on the base, and the ISOFIX interface is directly arranged on a side of the base. The top pole or support pole can be further provided on the base to provide a firmer fixation. In order to accommodate children of different ages, the seat may be rotated relative to the base to have a forward-facing mode and a rearward-facing mode. Generally, the forward-facing mode is suitable for older children to ride, and the rearward-facing mode is suitable for younger children to ride. It is more dangerous for younger children to use the forward-facing mode. However, the existing child safety seat does not provide a convenient misuse prevention mechanism to prevent the seat from being inadvertently rotated from the rearward-facing mode to the forward-facing mode. SUMMARY An object of one or more embodiments of the present disclosure is to provide a child safety seat, which can conveniently and reliably prevent the occurrence of the inadvertent rotation. In order to achieve the above object, in one aspect, the present disclosure provides a child safety seat comprising: a base; a rotatable seat above the base and having a forward-facing mode and a rearward-facing mode relative to the base; and a misuse prevention mechanism formed on the base and the seat and having a locked state and a released state, wherein when the misuse prevention mechanism is in the locked state and in the case that the seat is between the rearward-facing mode and a rotation threshold angle, a rotation angle of the seat in a first direction cannot be greater than the rotation threshold angle; and wherein when the misuse prevention mechanism is in the released state and in the case that the seat is between the rearward-facing mode and the rotation threshold angle, the rotation angle of the seat can be greater than the rotation threshold angle; the first direction is a rotation direction from the rearward-facing mode to the forward-facing mode. At least one embodiment of the present disclosure has at least one of the following beneficial effects. The child safety seat of at least one embodiment of the present disclosure can prevent the seat from being rotated by mistake. Specifically, the child safety seat of the present invention requires an additional operation to allow the seat to rotate from the rearward mode to the forward-facing mode, without preventing the seat from normally rotating from the forward-facing mode to the rearward-facing mode. This additional operation can be made on either side. Moreover, the child safety seat of at least one embodiment of the present disclosure can clearly indicate whether the seat is in the locked state or the released state.
