Abstract: A bolster for supporting an object. The bolster has a frame. A blower is mounted on the frame and configured to blow air through the bolster. A fabric cover includes air-permeable fabric stretched over and secured to the frame to provide cushiony support for the object. The fabric defines a support surface and a bolster interior and is positioned on the frame such that blown air from the blower flows through the bolster interior and passes through the fabric adjacent the support surface to provide ventilation.

Abstract: A chair assembly comprising a backrest, a fan assembly, and an airflow guide associated with the backrest in a manner such that airflow emitted from the fan assembly exits the chair assembly through the backrest. The assembly in various embodiments is, for example, a collapsible lawn chair, a quad chair, a bleacher chair, or an accessory for a wheelchair.

Abstract: Fan-equipped chair assemblies having a seat and a backrest. A fan assembly may be associated with a bottom of the backrest and oriented substantially upward toward a top of the backrest. An airflow guide may angle toward the top and away from the bottom of the backrest. A fan assembly may be associated with a rear of the seat and oriented substantially forward toward a front of the seat. An airflow guide may angle toward the front and away from the rear of the seat. An airflow guide may be associated with a bottom side of the seat, and a fan assembly may be attached to the airflow guide such that the airflow guide is located between the bottom side of the seat and the fan assembly. The air flow guide may at least generally taper from near the bottom side of the seat toward the fan assembly.
