Abstract
A joint for unfolding and locking a solar generator or a reflector, or other aerospace components that can be unfolded, includes two half joints, a joint axis, and a drive. A drive spring of the drive has a progressive characteristic curve over the unfolding angle of the two half joints, which increases over the unfolding, to compensate for a frictional torque that varies over the unfolding angle.

A joint for unfolding and locking a solar generator, a reflector, or other aerospace components that can be unfolded, consisting of:
- two half joints;
- a joint axis;
- and
- a drive, wherein a drive spring of the drive has a spring characteristic curve that compensates for a frictional torque that varies over the unfolding angle, the characteristic curve increasing over the unfolding progressively, over the unfolding angle of the two half joints.
