Abstract:
1. A camera stand head having a device ( 17 , 18 , 19 , 20 ) for attenuating a tilting movement and a device for compensating gravity torque occurring during the tilting movement, characterised in that the device for compensating gravity torque comprises at least one first fixed bearing ( 4 ), at least one second bearing ( 5 ) connected with an inclinable part as well as at least one torsion spring ( 7 ) arranged between said bearings ( 4 , 5 ), said torsion spring having adjustable torsion rigidity and comprising at least one spring bar ( 8 ), the axis of said spring bar being spatially offset in relation to the central axis ( 15 ) of the torsion spring ( 7 ), with the characteristic curve (torque over angle of rotation) of the torsion spring ( 7 ) extending essentially in a sinusoidal manner.
