AI Technical Summary
Existing cushions fail to effectively concentrate and distribute the load from the ischial tuberosities, leading to excessive compression and potential bottoming out, especially around the ischial tuberosities.
A cushion design with two storage compartments overlapping the ischial tuberosities, incorporating load-supporting cushions with higher density than the base cushion sheet, and additional layers such as a lower cushion sheet with higher hardness and a skin layer on the side surface of the load-supporting cushion to enhance support and stability.
The design effectively supports the concentrated load from the ischial tuberosities, preventing excessive compression and bottoming out, while maintaining a uniform seating surface and improving assembly efficiency.
