Embodiment Construction

[0027] The subject matter disclosed herein relates to passenger seats that can be adjusted in hot and cold conditions to provide thermal comfort to a seated passenger. These improved passenger seats provide greater thermal comfort to occupants during hot weather ground conditions by reducing the effective insulating value of the occupant's clothing. During cold conditions, this effect can be canceled, which increases the effective insulation value of the clothing of the seated occupants.

[0028] The variable thermal resistance passenger seat, disclosed in detail hereinafter, is intended to supplement (rather than replace) the vents by providing cooling to the surface supporting the seated occupant's body which can become hot and sweaty in hot weather conditions. The proposed seat provides this cooling function only on demand, such as during hot weather conditions, and not during cold cruising conditions where passengers typically desire enhanced insulation.

Abstract

The title of the invention is a variable thermal resistance device for vehicular seats. A seating assembly comprising: a frame having an opening; a support surface spanning the opening in the frame; a variable thermal resistance device that opposes the support surface when the variable thermal resistance device is in a closed state in which airflow is obstructed, the variable thermal resistance device being movable from the closed state to an open state in which airflow is not obstructed and from the open state to the closed state; and an actuator coupled to the variable thermal resistance device. The actuator is operable to actuate movement of the variable thermal resistance device between the open and closed states.

Description

technical field [0001] The present disclosure generally relates to passenger seats for vehicles. In particular, the present disclosure relates to passenger seats for aircraft. Background technique [0002] During hot ground conditions at the gate, aircraft air conditioning systems are often not powered, resulting in high temperatures in the passenger compartment. When a passenger or flight crew is seated, the seat increases the thermal resistance of their clothing, making them hotter. This causes seated passengers and aircrew to heat up, sweat, and feel unwell when the aircraft is on the ground. [0003] A current solution for thermal conditions in conventional aircraft passenger seats is to provide passengers and flight crew with individual exhaust vents (commonly known as "gaspers"). Vents increase heat transfer and evaporation (i.e. cooling) from the exposed surface of the seated body, but they may not provide cooling to surfaces covered by the seat cushion and fabric....
