Abstract
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.
Claims16
A ventilated seat, comprising:
- an air-permeable seat pad cover;
- a seat pad having a first surface, a second surface, and a void connecting the first surface with the second surface, the first surface being in fluid communication with the air-permeable seat pad cover;
- a three-dimensional mesh of a pre-determined shape disposed within at least a portion of the void of the seat pad;
- a first partition disposed on the second surface of the seat pad, the first partition having a full-thickness void in a pre-determined shape based on the pre-determined shape of the three-dimensional mesh;
- a second partition, adjacent to the first partition, comprising an air-impermeable material and including at least one full-thickness void, the second partition being a pressed material having a first layer and a second layer;
- and
- a ductless blower in fluid communication with the second partition,
- wherein the first layer of the pressed material is a polymer, a metal, a synthetic textile, or a combination thereof, and
- wherein the second layer of the pressed material is a polymer, a metal, a synthetic textile, or a combination thereof.
A seat pad assembly, comprising:
- a seat pad having a first surface, a second surface on an opposite face, and a void connecting the first surface with the second surface;
- a three-dimensional mesh of a pre-determined shape disposed within at least a portion of the void of the seat pad;
- a first partition of a pre-determined thickness disposed on the second surface of the seat pad, the first partition having a full-thickness void in a pre-determined shape based on the pre-determined shape of the three-dimensional mesh;
- and
- a second partition, adjacent to the first partition, comprised of an air-impermeable material and including at least one full-thickness void, the second partition being a pressed material having a first layer and a second layer,
- wherein the first layer of the pressed material is a polymer, a metal, a synthetic textile, or a combination thereof, and
- wherein the second layer of the pressed material is a polymer, a metal, a synthetic textile, or a combination thereof.
