Moreover, since the stable large base which is not influenced by the mounting direction is provided, the weight of the child seat is also heavy. On the other hand, various proposals for stably attaching a child seat as a popular product to a vehicle seat have been made.
  • Patent Document 1 The development point of popular child seats is to secure a wide bottom of the child seat at each mounting position. As a child seat focusing on this point, a proposal has been made in which a detachable block-shaped leg portion is rotated around a pivot axis in accordance with the mounting direction to change its position.
  • Patent Document 2 There is also a child seat that effectively prevents the child seat from rotating forward about the front end of the fixed point due to a frontal collision that occurs when facing forward, and that can secure a large bottom surface of the child seat even when installed backward. It has been proposed (Patent Document 2).
