[Problems to be solved by the invention]
By the way, there is a safety standard for the child seat 1, and the test is performed on the seat under the condition of “test seat with a seat elevation angle of 3 °” and the condition of the “test seat with a seat elevation angle of 3 °”. Based on the above, it is designed in consideration of infant safety and comfort.
However, the elevation angle α of the seating surface 2a of the vehicle seat 2 that is actually on the market is not 3 ° for every vehicle, and there are many that are set around 15 °. The actual situation is that there are a wide variety of elevation angles α.
Then, as shown in FIG. 5 (b), when the child seat 1 is installed rearward with respect to the traveling direction of the vehicle in order to put an infant whose neck is not sitting, the elevation angle α is adapted to the vehicle seat 2 having a 3 ° angle. When the child seat 1 manufactured in this way is used for a vehicle seat 2 having an elevation angle α of 15 °, the child seat 1 that is to be laid in the most laid state will actually get up by an increase of the elevation angle α by 12 °. Therefore, it is not preferable for an infant who does not sit on the neck. Further, the child seat 1 manufactured in correspondence with the vehicle seat 2 having an elevation angle α of 3 ° is changed to a vehicle seat 2 having an elevation angle α of 15 °, as shown in FIG. When installed forward, the person will sleep for an increase of 12 ° in the elevation angle α of the vehicle seat 2, and comfort for infants will be impaired.
