摘要：A Villari effect seatbelt tension sensor 10 comprises a sensor housing 30 having a sensor chamber 32 therein. A first end 34 of the sensor housing 30 has a plurality of pull rod holes 36 therein for acceptance of a plurality of pull rods 60. A Villari effect sensor 20 comprising a magnetostrictive sensor rod 22 is disposed axially within the sensor chamber 32 and abuts the first end 34 of the sensor housing 30. A plunger 40 is disposed within the sensor chamber 32 and is slidably movable therein. One end of the pull rods 60 is secured to the plunger 40. A spring 50 is disposed between the plunger 40 and a second end 26 of the sensor rod 22 to bias the sensor rod 22 toward the first end 34 of the sensor housing 30.
