If the included angle between the seat board and the backrest of the steam seat is set to be more than 100 degrees, the child can easily slide out from the backrest direction when the steam seat is impacted forward, so that the child is greatly injured. Therefore, in order to make the automobile seat form a strong enough protection effect on children when bearing high-speed collision, the included angle between the seat board and the backrest of the automobile seat is usually between 95 degrees and 100 degrees, and is usually in an integrally formed fixed angle form, and five-point safety belts are additionally arranged to restrict the children members between the seat board and the backrest together, so that a strong enough safety protection effect for protecting the children members when bearing external force collision can be formed.

However, after the automobile seat mode is switched into the child stroller mode, the running speed of a person pushing the child stroller is low, the safety belt is normally used in the pushing process, and the risk of the child sliding out from the backrest direction to be injured is low. The included angle between the seat board and the horizontal line is usually about 10 degrees, the included angle between the backrest and the horizontal line is adjustable between 95 degrees and 180 degrees, the riding comfort of children members can be increased as much as possible on the premise of ensuring low-speed running safety, and especially children of smaller ages can more comfortably adjust the angle between the backrest and the seat board by more than 110 degrees.

The user has the requirements of enough safety protection for high-speed collision of the seat and enough comfort in the pushing mode on the pushing seat, if the backrest or the seat plate of the seat is simply arranged in a rotatable opening and closing structure, the risk of misuse by the user can occur, namely, in the seat mode, the user possibly forgets or cannot skillfully adjust the angle between the seat plate and the backrest to be used under the safe angle, and the possibility of misuse injury can be increased.
