Abstract
A hinge for supporting a vent between a closed position in which it lies within a fixed frame and an open position in which it extends substantially perpendicularly to the fixed frame comprises a support track, a slider mounted on the support track and a vent arm attached to the support track via the slider by a plurality of links. The hinge further comprises a restricting member for acting between the support track and the vent arm wherein upon movement of the vent arm, the restricting member acts to further restrict movement of the vent arm. The slider includes a body portion and a restricting device for engaging the track, in use, to limit movement of the slider, wherein a portion of the restricting device extends into the body portion of the slider to provide reinforcement thereto.
