Abstract
The invention relates to a camera stand head comprising a device () for attenuating a tilting movement, and a device for compensating gravity torque occurring during the tilting movement. The device for compensating the gravity torque comprises at least one first, fixed bearing (), at least one second bearing () which is connected to an inclinable part, and at least one torsion spring () having adjustable torsion rigidity. Said torsion spring is arranged between the bearings () and comprises at least one spring bar (), the axis of the spring bar being spatially offset in relation to the central axis () of the torsion spring (). The characteristic curve (torque over angle of rotation) of the torsion spring extends essentially in a sinusoidal manner.
