Latest Patents
Hisatoshi Ishikawa holds a patent for a webbing take-up device. This device includes several key components: a take-up shaft, an attachment and detachment detection unit, a motor, a first transmission unit that transmits rotation of the output shaft in a first direction to the take-up shaft, and a second transmission unit that transmits rotation of the output shaft in a second direction to the take-up shaft. Additionally, the second transmission unit transmits the output torque of the output shaft to the take-up shaft, ensuring that the take-up torque does not reach a preset first torque. The control unit plays a crucial role by managing the drive voltage and current to ensure the output shaft rotates in the first direction when engagement between a tongue and a buckle is detected, allowing the take-up torque to reach a second torque that is higher than the first torque.
