A micro-circulation breathable cushion includes a cushion cover and a cushion core. The cushion core includes a breathable layer. At least one micro-circulation layer is disposed at a lower part of the breathable layer. The micro-circulation layer is connected to the breathable layer. The cushion cover wraps the cushion core, the breathable layer and the micro-circulation layer of the cushion core may be fixed together by glue or other manners, and may also be laminated together, thereby facilitating the replacement of different numbers of micro-circulation layers. The breathable layer may be directly washed, and an air micro-circulation is formed through an internal structure. An air micro-circulation may be likewise formed through an internal structure of the layer, and the breathable layer and the micro-circulation layer may co-form an air micro-circulation, thus increasing the breathability of the cushion core. Furthermore, different numbers of micro-circulation layers may be according to different temperatures.

The invention consists in an orthopedic seating wedge with ventilation channels. The wedge is manufactured in a CNC machining process from a chemically cross-linked polyethylene foam with density from 40 to 50 kg/m.sup.3. The orthopedic wedge, as illustrated on FIG. 1, has a profiled body (6), with a depression in the rear (3) to maintain a straight posture of the user as well as vertical (5) and horizontal (2) ventilation channels allowing skin air access, protrusions (4) to improve blood circulation in the skin tissue, as well an indentation in the tailbone area (1) in order to relieve the lower back and enhance sitting comfort.

Appropriate material hardness prevents deformations resulting from user weight, enables it to be used on various surfaces as well as allows the wedge to have the above mentioned features while ensuring adequate sitting comfort.

The present disclosure relates to a seat ventilation system for deployment in a seat of a vehicle. Specifically, the seat ventilation system includes a three-dimensional mesh for maintenance of airflow channels and a ductless blower system to prevent system pressure loss. The air-permeable three-dimensional scaffold prevents compression and closure of pad-based airflow channels. The blower system reduces system air pressure loss by residing adjacent to the volume of interest, eliminating the need for ductwork.

A vehicle seating assembly comprising a seat including a cushion and a seating surface. A recess is defined in the cushion extending in a direction parallel with the seating surface. An elongate carrier is disposed between the recess and the seating surface, the elongate carrier including a plurality of thermoelectric devices having an upper surface and a lower surface configured to change temperature when a voltage is applied to the thermoelectric devices. An upper conductor comprises an upper surface and a lower surface. A lower conductor comprises an upper surface and a lower surface. An air mover is in fluid communication with the recess and is configured to move air through the recess. The upper conductor, the thermoelectric device, the lower conductor, and air in the recess are in thermal communication to transfer heat away from the seating surface or to transfer heat toward the seating surface.

An elastic cushion includes two connecting rods, a plurality of elastic arc-shaped rods, and at least two flexible bearing members arranged an upper and a lower. The two connecting rods are arranged in parallel. The plurality of elastic arc-shaped rods are arranged side by side, and two ends of each of the elastic arc-shaped rods are respectively connected to two connecting rods; opposite side edges of each of the flexible bearing members are respectively connected to the two connecting rods and tension, and a cavity is formed between adjacent two of the flexible bearing members. when the user seats or leans on the elastic cushion, only the flexible bearing member at the topmost is contacted, and the air can flow smoothly in the cavity, so that the elastic cushion has excellent ventilation and breathability, facilitating the timely removal of odors and sweat, and avoiding skin diseases.

A cushion body includes a seat pad having a concave ventilation flow path extending along a pad rear surface of the seat pad, and a planar flow path lid covering the pad rear surface of the seat pad so as to cover the concave ventilation flow path. The seat pad has an expanded flow path in which a flow path width of the ventilation flow path is partially expanded, and the planar flow path lid includes a contact portion in contact with the pad rear surface, and a lid curved to cover the concave ventilation flow path including the expanded flow path at a position retracted to a seat rear side with respect to the contact portion.

The invention relates to a piece of outside furniture including a hollow space closed by a door; a lock for locking the door in position when the door is closed. The piece of outside furniture further includes a transmitter-receiver of an electromagnetic wave, the and the lock is configured to unlock the position of the door when a received electromagnetic wave, from a radio frequency identification tag having received an emitted electromagnetic wave, comprises predefined information. The piece of outside furniture further includes a through-opening, configured to allow the passage of a post planted in the ground.

A chair for providing support to a user's spine to improve posture and for providing ways for the user to perform exercises. The chair may include a flexible connection that enables a back support to move side to side through a sidebending range of motion of the user. The back support, which may include a flexible chair spine, may be configured to adapt to the curvature of the user's spine when the user is seated in the chair. A seat of the chair may include channels and vents to improve air circulation within the seat.

A device for supporting a person may include a thermoelectric generator configured to receive heat provided from the person. The device may further include a first heat conductor overlapping the first thermoelectric generator and configured to conduct the heat to the thermoelectric generator. The device may further include a second heat conductor overlapping the first heat conductor and configured to conduct the heat to the first heat conductor. The first heat conductor may be disposed between the first thermoelectric generator and the second heat conductor. The second heat conductor may be softer than the first heat conductor. The device may further include a heat sink thermally connected to the first thermoelectric generator.
