Abstract
(DE)
Ein Trägheitssensor (10), insbesondere an einem Gurtaufroller (12) hat wenigstens zwei Komponenten, die relativ zueinander reversibel beweglich sind und die jeweils wenigstens eine Kontaktfläche (20, 22, 34, 36) aufweisen, an der die Komponenten miteinander in Kontakt sind, wobei wenigstens eine der Kontaktflächen (20, 22, 34, 36) mit Graphitpulver (38) beschichtet ist.
(EN)
The invention relates to an inertia sensor (10), in particular on a belt retractor (12), having at least two components, which are reversibly movable relative to each other and which each have 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).
(FR)
L'invention concerne un capteur d'inertie (10), en particulier sur un enrouleur de ceinture (12). Le capteur d'inertie comprend au moins deux composants, qui sont mobiles de manière réversible l'un par rapport à l'autre et qui comportent respectivement au moins une surface de contact (20, 22, 34, 36), sur laquelle les composants sont en contact entre eux. Au moins une des surfaces de contact (20, 22, 34, 36) est revêtue de poudre de graphite (38).
