Abstract An air outlet device in a vehicle with an air conditioner comprises a duct which is disposed at the ceiling of the passenger compartment of the vehicle and communicates with the air conditioner. The duct is provided with a first set of air outlets and a second set of air outlets which are located downstream of the first set of air outlets. Within the duct, flow restriction means is disposed at a position downstream of the first set of air outlets and at the same time upstream of the second set of air outlets for restricting the flow rate of air admitted to the second set of air outlets. The first set of air outlets are adjustable to blow toward or away from a passenger of the vehicle. The second set of air outlets are fixed to blow in one direction and adapted to effect mild recirculation of air throughout the passenger compartment.

An air outlet device in a vehicle having a passenger compartment and an air conditioner comprising: a duct disposed at the ceiling of said passenger compartment in a manner to extend transversely thereof and communicating with said air conditioner; said duct having a first set of air outlets which are adjustable to blow in a multiplicity of directions slanting with respect to the floor of the passenger compartment and a second set of air outlets which are located downstream of said first set of air outlets and fixed to blow in one direction substantially perpendicular to the floor of the passenger compartment; flow restriction means disposed within said duct at a position downstream of said first set of air outlets and at the same time upstream of said second set of air outlets for restricting the flow rate of air admitted to said second set of air outlets below a predetermined value; in which the ceiling of said passenger compartment is defined by a wall including an outlet roof panel and an inner ceiling panel having a bead extending transversely of said passenger compartment; in which said duct is disposed in a space formed between said roof panel and said bead of the ceiling panel; in which said passenger compartment includes a front seat part and a rear seat part; in which said first set of air outlets are constructed to blow mainly toward said rear seat part of the passenger compartment; and in which said duct further includes a third set of air outlets which are adjustable to blow in a multiplicity of directions slanting with respect to the flow of the passenger compartment and which are arranged upstream of said flow restriction means, said third set of air outlets being constructed to blow mainly toward said front seat part of the passenger compartment.
