Ergonomically designed portable cooling seat

Ergonomically designed portable cooling seat description/claims

Current application relates to a portable seat, especially relates to an ergonomically designed portable seat that supplies cool air from air-conditioner of a car into gaps between back and bottom of a driver and driver's seat of a car, except perinea area and shoulder.

Most of modern passenger cars are equipped with air-conditioner combined with heater. Outlets of the cooled/heated air are developed on many points inside of a car. The air circulation system of a car is designed to circulate the air inside of a car swiping every corner of the indoor. On a hot summer day, most of drivers close the windows and turn on air-conditioner. However, sometimes, they want open the window for fresh out door air. But, as soon as the window is open, all the cool air flushed out side. Some portable seats are provided to keep the driver's seat cool. However, they are designed without any consideration about medical effects of cold air on a human body. It is well known for oriental medical science that long exposure of perinea area to cold temperature may worse hemorrhoids for men and leucorrhea of women. And direct contact to shoulder also worse frozen shoulder. It is purpose of the current application to provide a portable seat that is designed ergonomically to avoid such defects of the prior arts while supplying cool air from air-conditioner to the back and underneath of buttocks of a driver to prevent the driver's body oozed by sweats after long hours drive on a hot summer day.

However, none of the prior art illustrates a portable cooling seat that is designed ergonomically to avoid flaws of prior art.

Most of modern passenger cars are equipped with air-conditioner combined with heater. Outlets of the cooled/heated air are developed on many points inside of a car. The air circulation system of a car is designed to circulate the air inside of a car swiping every corner of the indoor. On a hot summer day, most of drivers close the windows and turn on air-conditioner. However, sometimes, they want to open the window for fresh out door air. But, as soon as the window is open, all the cool air flushed out side. Some portable seats are provided to keep the driver's seat cool. However, they are designed without any consideration about medical effects of cold air on human body. It is well known for oriental medical that long exposure of perinea area to cold temperature may worse hemorrhoids for men and leucorrhea of women. And direct contact to shoulder also worse frozen shoulder. It is purpose of the current application to provide a portable seat that is designed ergonomically to avoid such defects of the prior arts while supplying cool air from air-conditioner to the back and underneath of buttocks of a driver to prevent the driver's body oozed by sweats after long hours drive on a hot summer day. The ergonomically designed portable cooling seat according to current application has a flexible connection duct, a tiny blower that installed inside of the connection duct to facilitate introduction of air from air-conditioner into the air distributor, an air distributor, and a solid structure that is foldable along the center thereof. The portable cooling seat supplies cool air to the back and beneath of the buttocks of a driver, while avoiding undesirable point such as perinea and shoulder, to prevents driver's body oozed by sweat.
