Abstract
A headband for a protection helmet comprises a strip forming at least a part of a ring around a user's head. An adjustment device adjusts a circumference of the ring. The end of the strip is fixed to an attachment point that is movable with respect to the body of the adjustment device. A rotary actuator is connected to the adjustment device by means of a transmission so that rotation of the rotary actuator results in the attachment point being moved with respect to the body. The transmission comprises a flexible transmission shaft configured to transfer a rotary torque applied on the rotary actuator into a rotary torque applied on the adjustment device to move the attachment point and modify the circumference of the ring. A protection helmet comprises such headband.
