A Fluid Flow Control System (FFCS) door assembly includes a continuous belt and a plurality of rollers. The plurality of rollers support the continuous belt and define a first segment, a second segment, a third segment, and a fourth segment. The continuous belt includes a plurality of openings that selectively allow fluid flow to pass through the first segment, the second segment, the third segment, and the fourth segment when two openings of the plurality of openings align with the first segment, the second segment, the third segment, or the fourth segment.

Systems, methods, and apparatuses are described herein that provide a localized temperature solution to a local temperature issue. Sunloading on one side of a vehicle can create a localized heating issue for an occupant on the same side of the vehicle. An air curtain system on the driver's side of the vehicle can detect high sunloading and then direct airflow onto an interior surface of the vehicle such as a door and window. The airflow provides an ambient cooling solution between the occupant and the sun to mitigate the effects of high sunloading. The air curtain system can receive a further input to redirect airflow away from the interior surface and onto the occupant to provide a direct cooling solution to further mitigate the effects of high sunloading. Other features, including sensors and a control unit, for controlling the air curtain system are described herein.

An opening and closing device includes a casing that defines an air passage, a slide door that includes a door main body slidable to open or close the air passage, and a sliding gear that is disposed on one side of the door main body in its width direction and includes first teeth in a sliding direction, and a drive gear that is rotatable around its axis line extending in the width direction and that includes second teeth in a circumferential direction around the axis line such that the first teeth and the second teeth are arranged in engagement with each other. When the drive gear rotates, a driving force is transmitted from the drive gear to the slide door through the sliding gear to slide the slide door. The door main body is restricted from shifting in the width direction due to the rotation of the drive gear.

A partition seal portion of a second rotary door is located between an outer door portion and a partition rib. The partition seal member is pressed against a rib tip portion in a door radial direction and moves slidably while being in contact with the rib tip portion in conjunction with a rotation of the second rotary door. Accordingly, an increase of a width in a door axial direction required for a sealing configuration can be suppressed. Therefore, a seal between a side face outlet and a center face outlet can be secured while being preventing a length of a face outlet in the door axial direction from being short.

A climate control system includes an outlet shutoff mechanism and an HVAC plenum delivering conditioned air to the outlet shutoff mechanism. The outlet shutoff mechanism includes a housing, having a guideway and a first air discharge outlet, a flexible door, displaceable along the guideway between a first position and a second position, and an actuator feature to displace the flexible door.

The door main body is restricted from shifting in the width direction due to the rotation of the drive gear.

A vent assembly of a vehicle includes a vent having a vent opening through which an airflow is directed, and a primary duct operably connected to the vent to convey the airflow toward the vent opening. A pressure relief valve is located along the primary duct. The pressure relief valve is configured to open when a pressure of the airflow in the primary duct exceeds a threshold, to divert a portion of the airflow through the pressure relief valve.

A sliding door has a door main body and door support sections supported by contact with an inner wall of a guide groove. The guide groove has a groove lacking section having a size that the door main body can be inserted therefrom. When a first one of the door support sections that is the closest to a tip end of the sliding door is located within the groove lacking section, another one of the door support sections that is located opposite from the tip end of the sliding door through the groove lacking section satisfies a relational expression of A900.2L, in which A represents a distance from the tip end to an end of the another one of the door support sections on a separated side away from the tip end, and L represents a door width of the door main body.
