5 . The air deflector of claim 1 , wherein the plurality of fins includes a first fin and a second fin; and
the second fin is longer than the first fin.
6 . The air deflector of claim 5 , wherein the first fin is disposed radially outward from the second fin.
7 . The air deflector of claim 6 , wherein the plurality of fins includes a third fin and a fourth fin; and
the third fin is disposed radially outward from the fourth fin.
8 . The air deflector of claim 7 , wherein the first fin and the second fin are disposed at a first half of the aperture; and
the third fin and the fourth fin are disposed at a second half of the aperture.
9 . The air deflector of claim 1 , wherein the base further comprises a lip, the first side, and a second side, and wherein the lip is aligned with the first side of the base, the plurality of fins extends from the lip, such that a first end and a second end of a bottom edge of each fin is connected to respective portions of the lip.
10 . The air deflector of claim 9 , wherein the base further comprises a tube portion extending from the second side, and the tube portion is centered with the aperture, and wherein the plurality of fins is disposed outside the tube portion.
11 . The air deflector of claim 1 , wherein the plurality of fins extends beyond the flange.
12 . The air deflector of claim 1 , wherein the plurality of fins includes at least one of planar straight portions that are parallel to each other, and one of angled or curved portions extending from the planar straight portions, and wherein the planar straight portions are perpendicular to a plane of the base.
13 . A vehicle seat, comprising:
the air deflector of claim 1 ;
an air mover;
a duct connected to the air mover and a tube portion of the air deflector; and
an air distributor in fluid communication with the aperture.
14 . The vehicle seat of claim 13 , wherein the air deflector includes a flange that extends toward the air distributor and does not extend into the air distributor.
15 . The vehicle seat of claim 14 , wherein at least some of the plurality of fins extend into the air distributor.
16 . The vehicle seat of claim 13 , further comprising a seat cushion, wherein the air distributor is disposed at least partially in the cushion.
17 . The vehicle seat of claim 14 , wherein the first recess and the second recess correspond to at least a portion of the flange with a length that is smaller than a length of another portion of the flange.
18 . The vehicle seat of claim 14 , wherein the plurality of fins comprises a first fin and a second fin, such that the second fin is longer than the first fin and disposed radially inward from the first fin,
wherein each of the plurality of fins comprises a planar straight portion and one of angled or curved portion extending from the planar straight portion, and
wherein a first planar straight portion associated with the first fin is parallel to a second planar straight portion associated with the second fin and a first angled or curved portion associated with the first fin is parallel to a second angled or curved portion associated with the second fin.
19 . A vehicle seat, comprising:
an air mover;
a duct in fluid communication with the air mover;
an air distribution assembly in fluid communication with the air mover via the duct, wherein the air distribution assembly comprises:
an air deflector comprising:
a base comprising:
a flange that extends from a first side of the base, the flange comprising a first recess and a second recess disposed opposite to each other;
an aperture extending through the base; and
a plurality of fins extending from the first side of the base and the plurality of the fins are aligned with at least the first recess and the second recess to facilitate an air flow into and out of at least a portion of the aperture between the plurality of the fins and the flange of the air deflector; and
an air distributor in fluid communication with the aperture to facilitate the air flow at a surface of a cushion of the vehicle seat; and
an electronic control unit configured to control an operation the air distribution assembly.
20 . An air distribution system for a vehicle seat, comprising:
an air mover configured to generate air flow;
a duct in fluid communication with the air mover;
