TL;DR: In this paper, an open cell foam pad is ripple-cut to create a convoluted face of hills and valleys, and a plurality of air-flow channels are cut through the pad in each valley formed.
Abstract: An open cell foam pad is ripple-cut to create a convoluted face of hills and valleys. A plurality of air-flow channels are cut through the pad in each valley formed. The channels with plugs therein provide the user of the pad with the ability to direct air circulation through the pad to certain parts of the body. These air channels also function to dissipate excess body fluids or medicines. For situations demanding the highest possible amount of air circulation, the ripple-cut pad with open air-flow channels is flat-topped. The size of the flat area on each hill is determined by the weight of body to be supported. For a body weight under 100 pounds, a maximum area of 1/2 inch by 1/2 inch is used with a contact surface to open space ratio of 1:3. For a body weight between 100 and 150 pounds, a maximum area of 1 inch by 1 inch is used with a contact surface to open space ratio of 1:1. For a body weight greater than 150 pounds, a maximum of area of 11/4 inch by 11/4 inch is used.

TL;DR: A vehicle seat with a backrest cover is at least partially air permeable, and covers at least one passage of the air-handling device as discussed by the authors, where the air exchanged between the environment and the air handling device passes for the most part through the air permeable regions of the backrest covers.
Abstract: A vehicle seat with a backrest ( 16 ) that has a backrest cushion ( 18 ) and a rear backrest cover ( 20 ), and an air-handling device that is associated with the backrest ( 16 ) and is connected to an air distribution device ( 30, 32 ) in the seat. The rear backrest cover ( 20 ) is at least partially air permeable, and covers at least one passage ( 27 ) of the air-handling device ( 23 ). The air exchanged between the environment and the air-handling device ( 23 ) passes for the most part through the air-permeable regions of the backrest cover ( 20 ).

TL;DR: In this paper, the authors describe a cushion that includes a cushioning element, which is composed of a number of substantially parallel elongate columns formed in a gelatinous cushioning media.
Abstract: A cushion that includes a cushioning element. The cushioning element has a number of substantially parallel elongate columns formed in a gelatinous cushioning media. The columns are configured so that when a force is applied to the cushioning element in a direction that is generally parallel to the longitudinal axes of the columns, the cushioning element will yield by a combination of compressability of the cushioning media and bucklability of the walls of the columns. In particular, the walls of columns which are located beneath a protruberance on an object being cushioned tend to buckle, permitting the cushioning element to conform to the shape of the cushioned object while evenly distributing a supporting force across the contact area of the cushioned object and avoiding pressure peaks. The preferred cushioning media is a gelatinous elastomer or gelatinous viscoelastomer. Various configurations of cushioning elements, including sidewall supports, are disclosed.

05 Jan 2001TL;DR: In this paper, an integrally molded portion of the air plenum member is assembled into an air conduit for the air port, which can have various sizes that are larger than the box-like member and can have inner and outer surface conformations.
Abstract: A ventilated vehicle seat includes an imperforate foam air plenum member located in a foam cushion top. The air plenum member is assembled from a molded box-like foam member and an integrally molded cover. The air plenum has an air port for application of positive or negative pressure. The cover has apertures for air to pass into or out of the air plenum member. One preferred embodiment of the air plenum member includes an integrally molded portion that is assembled into an air conduit for said air port. The cover can have various sizes that are larger than the box-like member and can have inner and outer surface conformations to suit various purposes.
