Summary:A hinge for supporting a vent between a closed position and open position comprises a support track 1 and a vent arm 10 joined by a linkage 4,5,6,7. A seal slider 3 is movably mounted on the support track 1 and is biased away from a pivot point 2 on the support track 1 by a leaf spring 17. Upon closing the vent, a first cam surface on the seal slider 3 is engaged by an engagement member 13 on the vent arm 10. This forces the seal slider 3 towards the pivot 2 against the bias of the spring 17, and a second cam surface of the seal slider 3 engages a sealing block on the vent arm 10. This prevents the vent arm from moving outwards and bowing of the window thus providing improved weather sealing around the vent.
