Title
(EN) ROLL-OVER SENSOR WITH PENDULUM MOUNTED MAGNET
(FR) DETECTEUR DE CAPOTAGE A AIMANT MONTE SUR PENDULE
Abstract
(EN)
A shunt (34) is pivotally mounted to form a pendulum positioned between a reed switch (30) and a magnet (28). The shunt is formed of ferromagnetic material and is mounted such that as long as it remains between the reed switch and the magnet the reed switch remains open. The shunt is held or biased between the magnet and the reed switch by the force of the magnetic attraction between the shunt and the magnet. The mass of the shunt acts as both a tilt sensor (20) which responds to gravity and an accelerometer sensitive to crash-induced accelerations. The reed switch, magnet and shunt are mounted in a housing (22) which positions the reed switch and magnet and controls the maximum range of motion of the pendulum-mounted shunt.
(FR)
Une dérivation (34) est montée pivotante de manière à former un pendule positionné entre un commutateur (30) à lames et un aimant (28). La dérivation, constituée d'un matériau ferromagnétique, est montée de manière que, tant qu'elle demeure entre le commutateur à lames et l'aimant, le commutateur à lames reste ouvert. La dérivation est maintenue ou sollicitée entre l'aimant et le commutateur à lames par la force de l'attraction magnétique s'exerçant entre la dérivation et l'aimant. La masse de la dérivation fait à la fois office de capteur (20) de dévers, réagissant à la gravité, et d'accéléromètre, sensible aux accélérations induites par les accidents. Le commutateur à lames, l'aimant et la dérivation sont montés dans un boîtier (22), qui permet de positionner le commutateur à lames et l'aimant et d'agir sur la portée maximale de déplacement de la dérivation montée sur le pendule.
