Latest Patents

One of Iizima's latest inventions is a passive seat belt system designed for automotive vehicles. This system features webbing that can transition between a passenger restraining position and a passenger releasing position. It includes impact detecting means to identify any impact applied to the vehicle. Additionally, the system has door state change detecting means to monitor the opening and closing states of a vehicle door. When a change is detected, the signal output regulating means selectively outputs closing and opening signals for a predetermined time. Importantly, the system is designed to prevent the output of closing and opening signals when an impact signal is detected, ensuring that the webbing can be moved to the appropriate positions in response to the signals.

Another patent by Iizima focuses on a passive seat belt system that controllably restrains a passenger based on the vehicle door's states. This system comprises a seat belt that can either release or restrain a passenger. A door switch outputs signals corresponding to the door's opening and closing states, which are processed by a control circuit. The driving device is activated to move the seat belt to the passenger releasing position when the appropriate signal is received. An interrupting circuit is also included to prevent the seat belt from being released during a malfunction, thereby enhancing safety.
