Latest Patents

Among Doi's notable inventions, two recent patents stand out. The first is a seat designed to provide band-like support for the body sides of the user. This innovative design aims to reduce the pressure on the lumbar region while stabilizing the user's upper body. Specifically, the load on the seat is strategically positioned outside the back region defined by the angulus inferior scapulae and the upper ends of the iliac bones, ensuring that load ratios do not exceed 25% in the areas extending downward from the back region.

The second patent features a seat that includes a seat frame and a cushion material made from a three-dimensional knitted fabric. This cushion is formed by connecting a pair of ground knit fabrics that are separated from one another. The first region of the cushion exhibits elastic compliance similar to that of the occupant's body, while the second region offers greater elastic compliance. This innovative structure allows for a thin and lightweight seat that mitigates load concentration on the occupant's ischiatic tuberosity during extended seating periods, while also improving vibration transmission characteristics.
