Methods and apparatus are provided for active vehicle cabin occupant protection system. The method includes detecting a vehicle cabin temperature using a cabin thermal sensor, engaging a vehicle fan and opening a vehicle outside air ventilation duct in response to the vehicle cabin temperature exceeding a first threshold temperature, and starting a vehicle engine and engaging a vehicle air conditioning system in response to the vehicle cabin temperature exceeding a second threshold temperature wherein the second threshold temperature is greater than the first threshold temperature.

A fresh air intake device for a vehicle includes a pipe with a channel for providing air to a cabin of the vehicle. The pipe has a nozzle portion with a plurality of openings for distributing air into the cabin. The openings of the nozzle portion are arranged one after each other in a longitudinal extension direction of the pipe. A degree of taper of the air channel in the longitudinal extension direction of the pipe is adjustable for the nozzle portion for equalizing the distribution of air flowing through the openings.

A cargo space air management system for a vehicle includes a body defining one or more cavities therein and one or more ports configured to enable fluid communication through the one or more ports into at least one of the one or more cavities. The body is configured to attach to be placed in a cargo space of the vehicle, and the body is deployable from a first state to a second state, wherein in the second state the body covers a portion of the cargo space and forms an air filled cavity within the body.

A roof assembly for a vehicle cabin, particularly for the cabin of an agricultural machine, comprising a housing of plastic material and an air conditioning unit housed within the housing, and at least one air inlet fluidically connected to the air conditioning unit and arranged at a periphery of the housing, and a filter arranged downstream of the air inlet. An air inlet shield is arranged at the air inlet, said air inlet shield being mounted to the periphery of the housing and sealingly mounted to the air inlet, the air inlet shield comprising a pair of shaped plates of plastic material, peripherally welded to each other, between which a chamber fluidically communicating with the filter and with the outside of the roof assembly is defined.

A riding vehicle is provided with a downdraft fan assembly mounted on a vehicle roll bar for providing a flow of ambient air over the vehicle operator and a canopy carried by the fan assembly and providing solar and precipitation protection for the operator.

An overhead automatic Heating, Ventilation, and Air Conditioning (HVAC) apparatus can be installed in an overhead surface within various types of vehicles, structures, and buildings, in order to maintain comfortable temperature inside of the respective environment. The overhead automatic HVAC apparatus can be installed in the roof of an automobile, allowing the driver to return to a comfortable temperature. Also this provides safety, preventing a child left inside of the automobile from being harmed due to extreme temperatures. The overhead automatic HVAC apparatus can be installed in a roof of a military vehicle, such as an High Mobility Multipurpose Wheeled Vehicle (HMMWV), or the ceiling of an office inside of a commercial building. The overhead automatic HVAC apparatus can be self-powered, including a battery and a solar-powered generator which allows the overhead automatic HVAC apparatus to run when conventional AC units are off, reduces costs, and power consumption.

A duct system, and more particularly, a rigid endcap of the duct system can be configured to prevent a register from being damaged and from being displaced upon a curtain side airbag deployment. The duct system can include a headliner defining an opening, and a soft duct operatively connected to the headliner. The duct system can include a rigid endcap operatively connected to the headliner and to the soft duct. An airflow channel can be defined by the headliner, the soft duct, and the rigid endcap. Additionally, the rigid endcap can define a terminal end of the airflow channel, and the opening can be located along the airflow channel directly below the rigid endcap.

An air conditioning system for a vehicle including an air curtain assembly. The air curtain assembly includes an outer blower configured to generate an air curtain, and an inner blower configured to generate comfort airflow within the air curtain. The air conditioning system is configured to condition the comfort airflow with respect to at least one of the following: temperature, humidity, odor, particulate matter content, biological matter content, germ content, and infectious agent content.

A sports car provided with a conditioning system comprising a conditioning device for treating environmental air, an internal channel for delivering conditioned air generated by said conditioning device throughout a vehicle cockpit, wherein said conditioning device is arranged at the rear of said vehicle cockpit.

An air sanitizing apparatus for a vehicle comprising: an ozone generator; a negative ion generator; and an ultraviolet radiation source. The air sanitizing apparatus further includes a rotating feature and a motor operably connected to the rotating feature, the rotating feature configured to move the air sanitizing apparatus along a track system. The air sanitizing apparatus can includes a first end portion; a second end portion; a middle portion disposed between the first end portion and the second end portion, the middle portion rotatable relative to the first end portion and the second end portion about an axis that extends through both the first end portion and the second end portion. The ozone generator, the negative ion generator, and the ultraviolet radiation source are all disposed at the middle portion. The air sanitizing apparatus is disposed in an interior of a vehicle below but adjacent to a ceiling.
