The invention discloses an air bag, a seat comfort system and a seat, the air bag comprises an air bag body used for filling air; the light source assembly is used for emitting light; the sensing assembly is used for receiving the light rays emitted by the light source assembly and converting the light rays into corresponding electric signals; the light source assembly and the sensing assembly are oppositely arranged on the air bag body in the main deformation direction of the air bag body. The distance between the light source assembly and the sensing assembly can be influenced by the deformation of the air bag body, and different electric signals can be generated by different distances between the light source assembly and the sensing assembly, so that the height change or the bulging degree of the air bag body in the main deformation direction can be known according to the electric signals generated by the sensing assembly; and further, the inflation volume of the air bag is fed back and adjusted.
本发明公开了一种气袋、座椅舒适系统及座椅,气袋包括气袋本体,用于充装气体;光源组件,用于发出光线;感测组件,用于接收所述光源组件发出的光线并转化成对应的电信号;所述光源组件和所述感测组件沿所述气袋本体的主形变方向相对设置于所述气袋本体。由于气袋本体的形变会影响光源组件与感测组件之间的距离,光源组件与感测组件之间不同的距离会产生不同的电信号,因此,根据感测组件产生的电信号可以得知气袋本体的沿主形变方向的高度变化或鼓胀程度,进而对气袋的充气量进行反馈调节。
