Abstract: An air vent for a heating or air conditioning system comprising an air flow nozzle having a part spherical outer wall mounted within a housing which is substantially circular in cross section about a longitudinal axis and shaped to allow swivelling of the nozzle within it, the nozzle being mounted to the housing via a gimbal member, the gimbal member comprising two legs with a web extending between them, each leg extending between the housing and the nozzle wall in a longitudinal direction, each leg being pivotally attached to the housing at diametrically opposite points such that the gimbal member may rotate about a first axis with respect to the housing, the gimbal member also comprising a tongue extending from the web to the first axis between the pivot points of the housing and being pivotally attached to the nozzle about a second axis orthogonal to the first axis.
