Patent number: 11590928Abstract: A control device for a seat belt of a vehicle includes a retracting unit configured to retract the seat belt, a departure detection unit configured to detect a departure of the vehicle from a lane; a vehicle speed sensor configured to measure a vehicle speed; and an electronic control unit configured to operate the retracting unit when both a first condition and a second condition are satisfied. The first condition is a condition that the departure detection unit detects the departure of the vehicle from the lane, and the second condition is a condition that the vehicle speed is equal to or higher than a prescribed speed, and the electronic control unit is configured not to operate the retracting unit when the first condition is satisfied and the second condition is not satisfied.Type: GrantFiled: October 10, 2019Date of Patent: February 28, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takuya Nezaki, Motoki Sugiyama, Fumihito Komeno

Patent number: 11235722Abstract: A seatbelt system includes a take-up device configured to take up a seatbelt, and an electronic control unit configured to, when any one of first and second conditions is satisfied, cause a motor to take up the seatbelt. In the first condition, after occurrence of a collision whose physical quantity detected by a detector configured to detect the physical quantity associated with a magnitude of the collision is less than or equal to a first threshold, the physical quantity decreases to less than or equal to a second threshold. In the second condition, after occurrence of a collision whose physical quantity is less than or equal to the first threshold, a first predetermined time elapses, which is estimated to be equivalent to a decrease in the physical quantity to less than or equal to the second threshold.Type: GrantFiled: October 9, 2019Date of Patent: February 1, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takuya Nezaki, Motoki Sugiyama, Fumihito Komeno
