Takayuki Endou

Title: Takayuki Endou: Recliner Mechanism Inventor

Introduction

Takayuki Endou is an inventor based in Toyota, Japan, associated with Toyota Boshoku Kabushiki Kaisha. His work includes recliner mechanisms, and he is credited with 5 patents.

Latest Patents

Endou’s latest listed patents describe improvements to recliners, which use ratchets, guides, and pawls to control movement and support adjustment.

One patent focuses on how the pawl’s teeth engage with the ratchet’s inner teeth. It specifies that two adjacent tooth flanks near the center of the pawl’s outer tooth row make contact, while certain flanks farther from the center fit within the ratchet without touching it. This arrangement is designed to inhibit rotation between the ratchet and guide.

Another patent addresses the guide walls that support the pawl. Each wall includes a recessed weak portion spaced apart from the surface that contacts the pawl. Under a large load, the recess is designed to concentrate stress and deform plastically when the pawl is forced circumferentially, providing a controlled response to the load.

Career Highlights

Endou’s listed inventions concern the design and performance of recliner mechanisms. The patent descriptions highlight tooth engagement and structural behavior under load as areas of focus.

Collaborations

Endou’s listed coworkers include Hideki Uramichi and Makoto Esaki. The available information identifies them as coworkers but does not specify their roles in the patents.

Conclusion

Takayuki Endou’s patent work at Toyota Boshoku Kabushiki Kaisha includes recliner designs that address secure engagement and controlled deformation under heavy loads.
