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. |
