Abstract: A vehicle heating, ventilation and air conditioning system includes a plurality of ducts for providing conditioned air to an interior of a vehicle. The plurality of ducts includes a window defrost duct and a floor duct. The system includes a mixing chamber upstream of the window defrost and floor duct. A damper is selectively controllable to distribute the conditioned air to one or more of the plurality of ducts. The damper is configured so that when in a floor only mode position, the damper directs conditioned air in the mixing chamber only to the floor duct. A bypass conduit is configured to direct air from the floor duct to the window defrost duct when the damper is in the floor-only mode position. The conditioned air directed through the bypass conduit attenuates noise generated in the mixing chamber from emanating to the window defrost duct.

The enclosed passageway has a plurality of peripheral walls for guiding the air stream between the inlet and the outlet, including a curved outer peripheral wall corresponding to a region with a tendency for a high flow as a result of centrifugal effects. One of the peripheral walls includes a VBC receptacle formed as a depression into the peripheral wall having a substantially flat mounting surface and a first sloped side at an upstream end of the VBC receptacle to shape a portion of the diffused air stream.

Abstract: A plenum assembly for carrying air in a supply system includes a duct including an opening formed with an inner surface through which air can flow; a door supported for movement between multiple positions which distributes air to the desired output path; and a seal secured to the door. In a vehicles HVAC system, numerous doors are utilized to provide comfort to the passengers based upon user input. The potential exists that some positions of the doors my lead to unwanted noise. A modification to the seal of the door with variable gap widths alleviates this issue and improves satisfaction.

Abstract: A case for an HVAC system has at least two molded shells joined together along a parting line to enclose a heat exchanger chamber, a blower chamber, and a diffuser section. The diffuser section includes a floor, a ceiling, an outer wall, and an inner wall around a longitudinal axis. The walls provide an airflow path through the diffuser between the blower and heat exchanger chamber, and the airflow path makes a substantially right angle turn into the heat exchanger chamber which results in a tendency to create a high flow region at the outer wall because of centrifugal effects. The outer wall is shaped to form a wall guide partially projecting into the airflow path in the diffuser, wherein the wall guide has an upstream encroaching surface and a downstream retreating surface so that a portion of the guided air is directed from the outer wall toward the inner wall.

Abstract: A diffuser for carrying air flow to an evaporator in an air conditioning system of an automotive vehicle includes an inlet and an outlet, a wall extending between the inlet and the outlet, and a guide vane, extending at least partially between the inlet and the outlet, spaced from the wall by a containing a control region whose area ratio changes along a length of the guide vane.

Abstract: A lighting system for an automotive vehicle has a housing adapted for mounting to the vehicle with a generally outward facing backplate and at least one socket for an incandescent light source. A transparent lens cover is attached to the housing and forms an internal chamber between the lens cover and the housing. A staircase circulator on the housing comprises a plurality of steps and risers rising from the backplate toward the lens cover along a path that is spaced from the socket, wherein the path is generally along a natural convection flowpath of air within the chamber.

Abstract: A latch mechanism is provided for securing a storage compartment door within a vehicle. The latch mechanism includes a mounting bracket, a handle, and an undivided, one piece latching member. The latching member includes a main body portion, a first pliable leg portion, a second pliable leg portion, a first post portion, and a second post portion. The latching member is in a relaxed position when the handle is in the latched position and a flexed position when the handle is in the unlatched position. The handle includes at least one abutment member for displacing the main body portion of the latching member as the handle is pivoted from the latched position to the unlatched position. Displacement of the main body portion causes the first and second pliable leg portions to resiliently retract which retracts the first post member and the second post member from extended post positions to retracted post positions.

Abstract: An outer cover layer, for a panel that defines a rupturable deployment door of an air bag deployment system in an automotive vehicle, is formed with an invisible pre-weakened tear seam prior to being overlaid onto the panel. The outer cover layer material is pre-weakened along a defined door opening pattern by a single step impression of a variable depth scoring knife into the under surface of cover layer material. The scoring knife contains a series of cutting edges of varying depth and length along its length that coincides with the seam pattern. The scoring may be performed during the conveyance of the cover layer material by making a single impression of the scoring knife into the lower surface thereof so that the maximum cut depth does not penetrate the outer surface of the material.
