Title: Masanori Ukai: Innovator in Webbing Take-Up Devices

Introduction

Masanori Ukai is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of webbing take-up devices, holding a total of 2 patents. His innovative designs focus on enhancing the functionality and user experience of these devices.

Latest Patents

Masanori Ukai's latest patents include a webbing take-up device that allows for an increased number of rotations of a spool. This design ensures that the number of rotations from the start of deformation of a first energy absorption member until the start of deformation of a second energy absorption member can exceed one rotation. The device features a restricting tab at the open side of the engagement recess portion, which prevents the leading end of the stopper pawl from entering the engagement recess during the first rotation of the lock ring. This innovative mechanism enhances the reliability and efficiency of the webbing take-up device.

Another patent by Ukai focuses on a configuration where a restriction wall of a cam gear abuts a pin of a link in a switching section. This design ensures that the restriction wall does not actively move the link, regardless of the number of revolutions made by the cam gear. As a result, operation noise is minimized during the pull-out and take-up of webbing, providing a desirable user sensation during normal usage.
