Abstract

A belt locking mechanism for locking the drawn action for a belt has a bottom plate (410), a rotary member (420) rotatably supported on the bottom plate, and an elastic member (430) for applying force to the rotary member. The bottom plate (410) has a narrow slot (411) for inserting the belt and fixed friction parts (412, 413) adjacent to the narrow slot. The rotary member (420) has a movable friction part (422A) and is bearing the force applied by the elastic member (430) thereby the movable friction part (422A) is pressed to the narrow slot and the fixed friction parts (412, 413). A belt 380 drawn from the back side of the bottom plate (410) through the narrow slot (411) is clamped and locked among the movable friction part (422A) and the fixed friction parts (412, 413). If the rotary member (420) is made to rotate by conquering the force of the elastic member (430), the movable friction part (422A) is made to move from the narrow slot (411) and the fixed friction parts (412, 413), then the lock of the belt (380) will be released.

Description

technical field [0001] The present invention relates to a belt lock mechanism for locking a seat belt for a child seat, a head support mounting structure, a seat main body mounting structure, and a shopping cart. Background technique [0002] In store facilities such as supermarkets and large-scale retail stores in recent years, shopping carts are prepared to transport the products purchased by shoppers, and shoppers move around the store facilities while pushing the shopping carts, and put the products in the shopping cart. Shopping in the basket. In this way, since a plurality of products can be stacked in the shopping cart, the shopper can carry out shopping more easily than in the case of moving while holding the shopping basket. [0003] Furthermore, recently, as shown in Patent Document 1, shopping carts equipped with child seats are also spreading. In addition, since the shopping cart is moved while the child is seated in the child seat, in order to prevent the chil...
