Yoshihiro Shimizu

Title: Yoshihiro Shimizu: Vehicle Door and Lock Mechanism Inventor.

Introduction

Yoshihiro Shimizu is an inventor associated with Kariya, Japan, and Aisin Seiki Kabushiki Kaisha. His patent work includes mechanisms for operating vehicle doors and improving the child-protection function of door locks. The supplied information lists 2 patents.

Latest Patents

- **Actuator for operating vehicle door.** This invention describes an electric-motor-driven actuator in which a spring frictionally couples a wheel gear and an output gear during operation. When the motor stops, the spring separates the gears and allows the output gear to return to its initial position.

- **Child protecting mechanism in door lock apparatus.** This mechanism uses a child-protecting lever and an opening lift lever connected to an inside lever. Turning the child-protecting lever disengages the lift lever from the opening lever, preventing movement of the inside lever from being transmitted to the opening mechanism.

Career Highlights

Shimizu’s listed inventions address practical vehicle hardware, including powered door operation and child safety in door-lock systems. Both patents focus on the interaction of levers, gears, and springs to control how vehicle doors and locks respond to user input.

Collaborations

Shimizu is associated with Aisin Seiki Kabushiki Kaisha. The supplied information also names Shigeru Hayakawa and Ryoichi Fukumoto as coworkers.

Conclusion

Yoshihiro Shimizu’s listed patent contributions center on vehicle door actuators and child-protecting door-lock mechanisms, reflecting an emphasis on functional automotive components and safety.
