Breathable cushion
A breathable cushion in accordance with the present disclosure includes a frame arranged inside a cover. The frame includes an outer rim, an inner rim spaced apart from the outer rim, and a lattice extending between the outer rim and the inner rim and defining an internal void of the frame. Apertures are formed through the lattice of the frame. The apertures and internal void allow airflow through the frame.
1. A breathable cushion frame, comprising:
an outer rim;
an inner rim spaced apart from the outer rim; and
a lattice having a first webbing extending between the outer rim and the inner rim and a second webbing extending between the outer rim and the inner rim,
wherein a first shell defines the first webbing and first portions of the inner and outer rims and a second shell defines the second webbing and second portions of the inner and outer rims,
wherein a plurality of connectors are arranged along the inner and outer rims and configured to couple the first shell to the second shell,
wherein the connectors each include a receptacle coupled to one of the first or second shells and a fastener coupled to the other of the first or second shells,
wherein the fastener extends into and engages with the receptacle to hold the first shell to the second shell,
wherein the second webbing is spaced apart from the first webbing to define an internal void of the breathable cushion frame, and
wherein each of the first and second webbings includes a plurality of interconnected web members defining a plurality of apertures through the lattice.
2. The breathable cushion frame of claim 1 , wherein the internal void is continuous around the inner rim.
3. The breathable cushion frame of claim 1 , wherein inner rim defines an opening through the breathable cushion frame.
4. The breathable cushion frame of claim 3 , wherein the breathable cushion frame defines a continuous tube extending around the opening.
5. The breathable cushion frame of claim 1 , wherein the first webbing and second webbing are arranged closer together adjacent the inner and outer rims and farther apart between the inner and outer rims.
6. The breathable cushion frame of claim 1 , wherein the first webbing extends substantially along a first plane between the inner and outer rims, wherein the second webbing extends substantially along a second plane between the inner and outer rims, and wherein the first plane is spaced apart from the second plane.
7. The breathable cushion frame of claim 1 , wherein the plurality of apertures are distributed along the lattice in offset repeating patterns around the inner rim.
8. The breathable cushion frame of claim 7 , wherein apertures arranged along patterns closer to the inner rim have smaller opening areas than apertures arranged farther from the inner rim.
9. The breathable cushion frame of claim 8 , wherein the patterns are circular and successively smaller in diameter moving from the outer rim to the inner rim.
10. The breathable cushion frame of claim 1 , wherein the outer rim is substantially rectangular.
11. The breathable cushion frame of claim 1 , wherein the outer rim is oblong along a first direction, and wherein the inner rim is oblong along a second direction substantially perpendicular to the first direction.
12. A breathable cushion, comprising:
a cover; and
the breathable cushion frame of claim 1 arranged inside the cover.
13. The breathable cushion of claim 12 , wherein the cover is a fabric material.
14. The breathable cushion frame of claim 1 , wherein each receptacle defines a hole having a first diameter, wherein each fastener includes a stem and a head coupled to the stem, wherein the stem has a second diameter the same or smaller than the first diameter, and wherein the head has a third diameter larger than the first diameter.
15. The breathable cushion frame of claim 1 , wherein the first and second shells are symmetrical to one another.
16. The breathable cushion frame of claim 1 , wherein the first webbing and first portions of the inner and outer rims are unitary and integral, and wherein the second webbing and second portions of the inner and outer rims are unitary and integral.
17. The breathable cushion frame of claim 1 , wherein the first and second inner rim portions together define the inner rim, wherein inner rim defines an opening through the breathable cushion frame, and wherein the internal void is continuous around the inner rim.
