Title: Safety device of vehicle
Inventor: MIDORIKAWA YUKINORI
IPC: B60R22/00
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a safety device for vehicle, which can inform about existence of any danger without resorting to an audible or visual means. SOLUTION: A degree-of-danger predicting means 1 for vehicle collision is composed of a relative distance sensor 11, sleep sensor 12, interface 13, and MCU 14. The MCU 14 judges existence of a collisional risk and emits a danger signal when the time (t) till likely collision given by the sensor 11 is below the prescribed value t1 but over t2 or if the sleep sensor 12 emits an appropriate signal. The output signal from an oscillator 22 (at 200Hz) is fed to a motor 23, which takes up the seat belt or slackens it. As a result, the tension of the seat belt increases and decreases periodically. If the time (t) till collision is shorter than t2, the output voltage of a DC power supply 21 is impressed on the motor 23, which increases the tension of the seat belt so as to fasten the occupant to the seat.
