- 21 A winder for tensioning a curtain of a vehicle about a curtain roller, comprising a body adapted for mounting to the vehicle, the body mounting a rotatable member adapted to be engageable with a curtain roller so that, when engaged thereto, rotation of the member causes corresponding rotation of the curtain roller, and wherein the rotatable member is coupled and coaxial to a toothed wheel; a rotatable handle operable by an operator; a disengageable first pawl engaging the handle and the toothed wheel, the first pawl able to be biased into engagement with a tooth of the toothed wheel such that rotation of the handle in one direction of rotation imparts rotation to the toothed wheel in a first direction to tension the curtain; and a disengageable second pawl able to be biased into engagement with a tooth of the toothed wheel so that when the toothed wheel is under torque from the rotatable member, the second pawl resists the torque from the rotatable member to inhibit rotation of the rotatable member and the toothed wheel in a second direction counter to the first direction of rotation of the rotatable member, wherein the second pawl is able to be disengaged from the respective engaged tooth and along a disengagement path that is unobstructed by the respective tooth. - 1 -3
