INERTIA SENSOR AND METHOD FOR REDUCING THE FRICTION BETWEEN TWO COMPONENTS OF AN INERTIA SENSOR

摘要

An inertia sensor (10), in particular provided on a belt retractor (12), includes at least two components which are reversibly movable relative to each other and each of which includes at least one contact surface (20, 22, 34, 36) on which the components are in contact with each other, wherein at least one of the contact surfaces (20, 22, 34, 36) is coated with graphite powder (38).
