    Abstract: A ventilation device for a vehicle includes an instrument panel having a front passenger region with a front instrument panel wall region facing a windshield and a rear instrument panel wall region as a potential head-impact instrument panel wall region. An individual vent air-feeding duct, which is covered by the instrument panel, extends below the potential head-impact instrument panel wall region and extends there essentially in a direction of the transverse axis of the vehicle. A front passenger airbag module can therefore be positioned away from the potential head-impact region in a free space formed in front of the individual vent air-feeding duct. The front instrument panel wall region has, at least in some regions, air passage openings for a diffuse ventilation of the vehicle interior. Starting from the individual vent air-feeding duct, at least one branch duct is guided to a region below the air passage openings.

  • Patent number: 6786469
    Abstract: Disclosed is an anti-rattle valve feature for a heating, ventilating, and air conditioning assembly. In a typical HVAC assembly each end of an air valve shaft is received in a pivot hole permitting the air valve shaft to rotate within the assembly. Because the inside diameter of the pivot holes are larger than the outside diameter of the ends of the air valve shaft, the air valve shaft may rattle within the pivot holes. Disclosed is a finger that contacts the air valve shaft to apply pressure to the air valve shaft and biases an end of the air valve shaft against the inside of it pivot hole, thereby preventing rattling of the air valve shaft within its respective pivot holes.

  • Publication number: 20040102151
    Abstract: In an initial stage of a cool down operation of a vehicle air conditioner, a rapid cooling operation is performed while cool air is directly blown to a passenger from direct air outlets. In a later stage of the cool down operation of the vehicle air conditioner, a temperature of an inner wall portion of a passenger compartment is reduced while cool air is indirectly supplied to the passenger of the passenger compartment from the indirect air outlet. Accordingly, cool air can be locally blown to the passenger in the initial stage, and cool air can be supplied to the entire passenger compartment while restricting an adverse effect due to heat radiation of the inner wall portion in the later stage. Thus, operation performance of the air conditioner can be improved while comfortable air conditioning feeling can be given to the passenger in the passenger compartment.

  • Patent number: 6598670
    Abstract: In a vehicle air conditioner, a defroster opening and a foot opening are provided at both right and left sides of a face opening. An outlet portion of a warm air passage has an enlarged portion offset to right and left side of the outlet portion of the cool air passage. During a bi-level mode, cool air from the cool air passage flows toward the face opening, and warm air from the warm air passage flows toward the foot opening, On the other hand, during a foot/defroster mode, cool air from the cool air passage and warm air from the warm air passage are mixed at an Inlet portion of the foot opening and the defroster opening and the mixed air is introduced into the foot opening and the defroster opening.

  • Patent number: 6588495
    Abstract: The present invention provides anchor tabs at opposite ends of a film member that are anchored to side faces of a door plate of a sliding door. Draft deflectors prevent the inflow of air to between the anchor tabs and the side faces of the door plate. Thus, inflow of air to between the anchor tabs of the film member and the side faces of the door plate is prevented. Also, fluctuations in pressure difference between the inner and outer sides of the anchor tabs are suppressed, and the production of extraneous noise caused by self-excited vibration of the anchor tabs at the ends of the film member is suppressed.

  • Publication number: 20030119439
    Abstract: The present disclosure relates to an airflow control apparatus having a plurality of doors and outlets for controlling the airflow in a vehicular HVAC system. In one aspect, the apparatus (100) has a first chamber (106) controlled by a first door (126) and having a first outlet (110) and a first passage (127). A second chamber (129) is coupled to the first passage and also controlled by the first door. The second chamber has a second outlet (130) and a third outlet (160) which are each controlled by the second and third doors (232, 242). According to another aspect, a method of controlling airflow in a vehicular HVAC system is disclosed. The method comprises the steps of receiving (702) airflow into a first chamber; controlling the airflow out of the first chamber with a first door; controlling (704) the airflow from a second chamber to a driver zone with a second door; and controlling (706) the airflow from said second chamber to a passenger zone with a third door.

  • Patent number: 6579167
    Abstract: A door and housing assembly for controlling air flow through the housing. The housing is adapted to be mounted in a ventilating system for controlling the direction and flow of air passing through the system. The door is actuated to move between two end positions where the respective air pathways are each sealed. The door can be positioned at any location between the end positions to control air flowing to the respective air pathways. The door includes guide pins on edges thereof that move along slots located in the inner sidewalls of the housing and guide the door between its end positions to locate the door in selected intermediate positions thereof. The slots for guiding the door may be steeply angled with respect to the seals so as to create minimal wiping of the respective seals upon engagement and dis-engagement between the door and seals at end positions of door travel.

    Abstract: An air-conditioning case of an air-conditioning unit forms air passages therein. A film member is reciprocably supported in the case and has free ends. Reinforcing members are secured to the lower end of the film member. A drive force for reciprocating the film member is applied to the film member from a motor through a drive shaft and drive gears, which are attached to the drive shaft, to open and close the air passages with the film member. When the film member is moved upwardly, the reinforcing members abut against positioning portions of the case to position the film member at a predetermined position.

  • Patent number: 6568468
    Abstract: In an air conditioning apparatus for a vehicle, a first cool air bypass passage is provided at an upper side of a heater core, and a second cool air bypass passage is provided at a lower side of the heater core. Cool air from the first cool air bypass passage and warm air having passed through the heater core are mixed in a first air mixing chamber, and a ratio between an amount of cool air and an amount of warm air is adjusted by an air mixing film member. Further, cool air from the second cool air bypass passage and warm air from the heater core are mixed in a second air mixing chamber, a ratio between an amount of cool air and an amount of warm air is adjusted by an air mixing door, and the second air mixing chamber is provided at an immediately downstream air side of the heater core. Thus, in the air conditioning apparatus, a pressure loss in a ventilation system can be reduced.
