Abstract:
A climate control system for a vehicle, the system including an air flow direction means arranged in use to operate according to a control quotient so as to present an air flow in a range of orientations substantially towards an occupant of said vehicle, a said presentation in a said orientation being dependent upon a plurality of environmental factors which are consolidated into said control quotient, said system being characterised in that said range of orientations are arranged in groups which include at least one base orientation group having a plurality of base orientation levels and at least one intermediate orientation group which comprises one or more intermediate orientation levels between two neighbouring said base orientation levels, and in that said air flow direction means is arranged to pass, if moving between said neighbouring base orientation levels, at least transiently through the or each said intermediate orientation level, whereby a variation in said presentation of said air flow between said neighbouring base orientations appears to a user to be more gradual than would be a substantially stepped change if made directly therebetween.
