[0002] Zero gravity car seat refers to a new type of seat designed by combining the zero gravity principle and car seat technology. This seat adopts ergonomic design and zero gravity technology. Sitting on the seat puts people in a natural state. The zero gravity seat suppresses the discomfort caused by the earth's gravity to a certain extent. The center of gravity of the human body is placed in one place, and other parts of the body are not under pressure. Riding in this state will make the body very relaxed.

[0003] The block values ​​of zero-gravity seats currently on the market are all very high. The h-point (hip point) is usually the design reference point of the car seat, and the vertical distance from the h-point to the bottom surface of the slide rail is called the block value, which is an important indicator of the seat space. In order to meet the design needs of some models, especially pure electric vehicles, more structural or functional modules are configured under the seat. Therefore, such models expect the seats to have a lower block value. However, if the block value of the car seat frame is low, if a zero-gravity seat is used, the seat inclination cannot be adjusted. The zero-gravity seat surface must be tilted backwards, and the angle between it and the backrest must be at least 95°, and the zero-gravity unit cannot be used.

[0004] Based on this, we need to develop a zero-gravity mechanism so that the zero-gravity unit can be used when the block value of the car seat frame is low. Utility Model Content
