L'amenée de liquide lave-glace peut également être intégré à l'élément de recouvrement. Par ailleurs, l'élément de recouvrement est conçu de telle sorte que le balai d'essuie-glace, le bras d'essuie-glace et l'élément de recouvrement peuvent être séparés les uns des autres. L'élément de recouvrement, à l'état de repos, referme l'espace formé entre le capot et le pare-brise et peut, à des fins de fonctionnement, passer à un état compact par l'intermédiaire d'un mécanisme.
