     DETAILED DESCRIPTION 
     In order to explain the technical contents, structural features and achieved effects of the present disclosure in detail, the following detailed description will be made in combination with the embodiments and accompanying drawings. 
     The safety seat in the related art may adjust a space for the seat by pulling the adjustable protector forwards for a certain distance and then loosen the safety belt. However, since the protector may be separated from the seat body, the positioning of the protector in the above adjustment method is unreliable and it is prone to unexpected situations. At present, there is a safety seat in which the protector may be fixed between the seat and the armrest by providing a detachable connecting mechanism at the rear end of the protector. However, in this way of connection, the protector cannot be adjusted relative to the seat body, resulting in an un-adjustable seating space of the safety seat. 
     Thus, this kind of safety seat cannot adapt to the children of different ages in different sizes, i.e., it is not suitable for a child with a larger size. Thus, the present disclosure provides a safety seat, which solves or at least relieves the above problem in the related art. 
     As shown in  FIG. 1 , a safety seat  400  of the present disclosure includes a seat body  401  and an adjustable protector  100 .
