ABSTRACT:
A segmented cover assembly for a vehicle seat or a mattress has multiple segments hingedly joined together to fit between cushioning and the body to blow temperature and humidity controlled air through an air permeable front cover to the body surface that normally is applied directly to the cushion. This prevents chilling, heating, and sweat build up. It also may reduce bed sores when applied to a mattress. A connector assembly is applied to the vent of an air conditioner. The connector assembly has a first outlet that replaces the original vent of the air conditioner and a second outlet to which is removably connected a duct that is connected to each segment. Valves selectively control air flow through each segment and the first outlet. Each segment has an air-impermeable rear panel and sides and an air permeable front panel separated from the rear panel by spacer elements that prevent collapse of the space between front and rear panel to ensure free passage of the conditioned air. The assembly is arranged for easy installation and removal without special skills or tools and that does not disturb the original operation of the air conditioner.
