Problems solved by technology

[0002] The backrest of a general seat is combined with the seat in a fixed and non-movable manner. When the occupant sits on the seat, his back leans against the backrest in a fixed state. The waist hangs in the air for a long time without any support, which causes discomfort in the back and waist of the occupant

[0003] The traditional sitting and lying auxiliary backrest support device often appears in the form of an elastic member installed on the seat. This device plays a certain role in supporting the occupant and improves the comfort of the occupant to a certain extent. However, the traditional The elastic parts have the following problems when supporting them. First, the supporting position of the traditional elastic parts is mainly adjusted by the occupant's own weight and the position when sitting down. Constantly adjust the position of the elastic part to adapt to the relative support position. In actual use, due to differences in body shape and height, different occupants have different requirements for the moving distance of the support plate. It has been determined at the time that it cannot be customized for each occupant. In this way, it will bring a lot of inconvenience to the occupants, thus affecting the occupants' experience

2. The traditional sitting and lying auxiliary backrest support device cannot automatically adjust the backrest angle required by the occupant when riding, nor can it automatically adjust the appropriate height of the backrest device and the left and right support positions on the back according to the individual differences of the occupants
