BETÄTIGUNGSVORRICHTUNG MIT EINEM AUS FORMGEDÄCHTNISMATERIAL BESTEHENDEM, FLEXIBLEM KABEL

摘要

An actuator including a shape-memory flexible cable with a flexible sheath (3) can be used, by controlling it both electrically and mechanically using the sheath (3) as element for applying a mechanical tensile force. The shape-memory flexible cable (2) is provided with a coating made of synthetic or elastomer material (106) moulded thereon and adherent thereto, which favours rapid return of the shape-memory cable into its resting configuration after its activation both on account of its elastic return and owing to the fact that it favours cooling of the cable. Preferably, the coating (106) is obtained by means of a process of co-extrusion with the shape-memory cable.
