The present invention relates to an arrangement at a cellular mobile telephone apparatus (1), comprising a protective hatch or flip (2) pivotably arranged on a housing (3) of said apparatus (1). The flip (2) is pivotable around an axis and arranged to at option physically cover at least parts of a front surface (5) on said apparatus (1), said axle comprises at least one active hinge means arranged in a cavity (7) each, at the end of said housing (3), of which at least one of said hinge means is aimed to positively urge said flip (2) to take a certain predetermined open position, when released. The active hinge means (6) comprise a shaft arrangement, colinear with said axis, comprising at least one unit (6) built from an end piece (9) and an elongated core (10) fixedly connected thereto, around which core (10) a torsion spring (11) is arranged. The spring (11) has at its respective ends fingers (12, 13) as counteracting parts for acting against a limit stop ridge (29) in the housing, for allowing said spring (11) to reach an equilibrium position corresponding to an open flip (2) at 120-170° from said closed position. |
