<P>PROBLEM TO BE SOLVED: To provide a cushion, especially as a cushion to be used for a wheelchair, which: disperses the body pressure of a user without sharply changing the body pressure by continuously changing repulsive force of a cushion material in an anteroposterior direction of the user; and, at the same time, enables the user to properly select the cushion as either hip-forward-slide preventing application or a leg pedaling application. <P>SOLUTION: The cushion 10 has an approximately square flat shape. A gel sheet 20 is arranged in the upper layer section, a low repulsion cushion material 30 is arranged in the intermediate layer section, and a high repulsion cushion material 40 is arranged in the lower layer section. The gel sheet 20 is constituted of two regions of a first honeycomb structure 21 and a second honeycomb structure 22. The low repulsion cushion material 30 has a structure wherein the bottom surface has an inclination. In order to correspond to the inclination, the upper surface of the high repulsion cushion material 40 has an inclination to be symmetrical to the low repulsion cushion material 30. The cushion 10 has a constitution wherein when respective slopes are arranged by stacking them, a rectangular parallelepiped is formed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
