Abstract:
An air cushion, a saddle, a seat cushion and a backrest having a curved upper surface, and a manufacturing method of an air cushion. An air cushion having a curved upper surface comprises a seat surface (1) and a base plate (2). The seat surface (1) is a flexible thin wall. The periphery of the seat surface (1) is sealingly connected at the base plate (2). Respective regions of the seat surface (1) are configured to have different wall thicknesses, such that the seat surface (1) has a curved structure fitting the curves of the body after the air cushion has been inflated, thereby fully fitting to the regions of the body experiencing a force, and improving sitting and rest comfort. Flexible sheet members (13) are employed to divide a space under a seat surface (1) of a saddle into multiple inflatable cavities, such that a formed curved structure can maintain the attractive appearance of the saddle, and a rider can adjust a degree of inflation of the inflatable cavities corresponding to the respective regions, thereby improving sitting and riding experience.
