The holding arm has an integrated pivot unit (1) which can be locked in at least two positions, fitted between two arm sectors (2,3), the turning axis of which is transverse to the longitudinal direction of these sectors. A locking element (22) is fitted to one arm sector (2). The other arm sector (3) carries a sprung counter locking element (25), which is fixed against turning, but can move in the engagement direction relative to the arm sector. The counter element is on a carrier (26) with a fixed end (28) on the arm sector. |
