Latest Patents

Hatta's latest patents include advancements in side impact air bag systems. One of his inventions features a first vent hole and a second vent hole designed to reduce the pressure opposing a passenger's chest to a lower value than that opposing the abdomen. This design ensures that the air bag maintains a desired internal pressure and inflation condition, effectively cushioning the impact on the chest while preventing early gas discharge. Additionally, the vent holes are strategically placed to avoid contact with vehicle compartment structural members, ensuring they remain unobstructed even during deformation of the vehicle structure.

Another patent focuses on regulating the gas blowing direction by connecting the air bag to an inflator through a gas intake portion. This design suppresses gas diffusion and improves the restraining condition of the passenger. The air bag is constructed with a main body, a lower inflation unit, and an upper inflation unit that includes a vent hole. This configuration allows for optimal inflation from the abdomen area, which has a higher shock load resistance, thereby enhancing passenger safety.
