Latest Patents

Choi’s recent patent work addresses the precision and operation of safety mechanisms used in vehicles.

- Acceleration Sensor and Seat Belt Retractor. This invention is designed to position an acceleration sensor’s lever precisely and support stable operation. The lever can rotate and shift along its axis as it responds to an inertia mass. A limiting portion restricts axial movement, helping prevent contact between the sensor’s base and its supports. The patent also describes a seat belt retractor incorporating the sensor.

- Seat Belt Retractor. This invention describes a retractor with a locking mechanism that prevents a spool from turning in the webbing-extraction direction. A clutch, ratchet gear, locking gear, biasing member, and connecting mechanism work together to control the lock. When webbing extraction is locked, the clutch remains biased in the extracting direction, reducing the amount of webbing that must retract before the lock releases and enabling quicker release.

Career Highlights

Choi’s disclosed inventions focus on components that support reliable seat belt operation, including sensor positioning and retractor locking and release. His work is associated with Ashimori Industry Co., Ltd., a company involved in automotive safety products.
