A zero-gravity seat cushion with a heat dissipation and breathability structure

Abstract

This invention belongs to the field of sponge cushion technology, specifically a high-elasticity sponge for a zero-gravity seat cushion with a heat dissipation and breathability structure. Addressing the problem that existing bucket-type sponge cushions cannot adjust firmness, this invention proposes the following solution: a base made of rigid sponge material. The base has an overall cuboid structure, with two longitudinal and parallel isolation grooves on its upper surface, dividing the upper surface of the base into three equal parts. On both sides of the two isolation grooves, there are recessed grooves, each containing an inflatable bladder. A central groove is located in the middle of the upper surface of the base between the two isolation grooves. This invention allows the user to initially feel the soft side cushion when sitting lightly, and then sink into the inflatable bladders. The overall firmness is adjusted according to the amount of air inside the bladders; if the user prefers a softer feel, less air is inflated, allowing for a deeper sinking.

Description

Technical Field

[0001] This invention relates to the field of sponge seat cushion technology, and more particularly to a zero-gravity seat cushion with a heat dissipation and breathability structure. Background Technology

[0002] With the continuous development of the automotive industry, people have increasingly higher requirements for the comfort, load-bearing strength, craftsmanship, appearance, and quality of car seats. Car seats must be designed to be comfortable for both driver and passengers, and can be moved forward and backward, with the height adjustable to suit individual body shapes, ensuring a comfortable seating posture and convenient control of the steering wheel and pedals. The backrest and seat cushion of car seats are mostly filled with molded foam, a porous material with excellent water absorption. After processing, the foam needs to be cut into different shapes according to different applications.

[0003] Existing car seat cushions have shortcomings in use. They rely solely on the elasticity of the foam itself for shock absorption, which results in less than ideal shock absorption and an ineffective shock reduction range. Furthermore, the foam is prone to collapse, affecting the lifespan of the foam seat cushion. Summary of the Invention

[0004] This invention proposes a zero-gravity seat cushion with a heat dissipation and breathability structure, comprising a base made of rigid sponge material, sufficient to provide overall support. The base has a rectangular structure, and its upper surface has two longitudinal and parallel isolation grooves that divide the upper surface of the base into three equal parts. On both sides of the two isolation grooves, there are recessed grooves, each containing an inflatable bladder. A central groove is located between the two isolation grooves on the upper surface of the base, containing an elastic mesh. The bottom of the base is located below the two recessed grooves. It has cylindrical grooves, and the bottom of the grooves has concentric circular holes that connect to the inside of the base. The upper surface of the base is located at the top of the two recesses and is attached to the side cushions with sponge adhesive. The upper surface of the base is located above the middle groove and is attached to the middle cushion. Both the side cushions and the middle cushion are made of soft sponge material. With the base having an inflatable bladder inside, the user can first feel the soft side cushions when sitting lightly, and then press down on the inflatable bladder as the whole body sinks. The overall firmness is adjusted according to the amount of air inside the inflatable bladder. If the user prefers a softer feel, less air is inflated so that the whole body can sink deeper.

[0005] A further design feature is that the lower surfaces of the two side cushions have the same shape, and the lower surfaces of the side cushions have protrusions whose shape matches the size of the opening at the top of the recess. The lower surfaces of the protrusions have equally spaced ventilation slots, the depth of which is less than the overall thickness of the side cushions, meaning there are no holes in the upper surface of the side cushions. By using the protrusions and the ventilation slots on their lower surfaces, not only can the bonding area between the lower surface of the side cushions and the base be increased, making the whole structure more secure, but the flatness of the upper surface of the side cushions is also ensured while increasing breathability, reducing the possibility of dust falling inside.

[0006] A further feature is that the upper surface of the middle pad of the side seat cushion is designed in a wavy, undulating shape, and a gap is left between the side seat cushion and the middle pad. The gap is located directly above the isolation groove, which makes it easier to distinguish each seat and reduce mutual influence.

[0007] A further feature is that the elastic net has fabric strips sewn along its edges, and pull ropes are fixed at equal intervals along the opposite edges of the elastic net. The ends of the pull ropes on both sides that are away from the elastic net pass through the middle partition of the base and are fixed with pull rods. By using the elastic net with fabric strips along its edges, and with the support of the pull ropes and pull rods passing through the base, the load-bearing capacity of the elastic net can be enhanced.

[0008] A further feature is that both sides of the intermediate groove have through holes that communicate with the sink groove, and the two pull rods are located above the through holes on both sides respectively; when the airbags on both sides are compressed during use, the airflow can be squeezed into the intermediate groove to increase the exhaust speed.

[0009] A further feature is that a down pouch is placed at the bottom of the middle groove, with the top of the down pouch abutting against the lower surface of the elastic net, thus improving the softness of the middle section.

[0010] A further feature is that the four vertical edges of the base are rounded, and the four edges of the base, side cushions, and middle cushion are smoothed after assembly to ensure that the rounded corners of the four edges can overlap, which facilitates the later leather wrapping process.

[0011] A further feature is that spring ropes are fixed at all four corners of the inflatable bladder, and anti-detachment caps are fixed at the front and rear sides of the base through which the spring ropes pass. The anti-detachment caps ensure that the inflatable bladder always remains in the middle position inside the base.

[0012] A further feature is that the base has strip-shaped grooves and arc-shaped grooves on its front and rear sides, respectively, corresponding to the positions of the spring ropes. Both ends of the strip-shaped grooves and arc-shaped grooves have stepped holes. The four spring ropes on the same airbag pass through the four stepped holes, and the diameter of the stepped holes is smaller than the diameter of the anti-slip caps. Straight locking plates and arc-shaped locking plates are respectively engaged in the strip-shaped grooves and arc-shaped grooves, and both ends of the straight locking plates and arc-shaped locking plates have anti-slip notches that match the diameter of the spring ropes. During installation, the four anti-slip caps on the outer wall of the airbag can be tightly fixed to the outside of the base.

[0013] A further feature is that an inflation nozzle is provided on the side of the airbag near the arc-shaped groove, and an anti-detachment ring is fitted onto the outer wall of the inflation nozzle and embedded in the base; the air volume of the airbag can be adjusted from the outside through the anti-detachment ring.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The base with an internal air bladder allows users to initially feel the soft side cushion when they sit lightly. Then, as the body sinks, it presses against the air bladder. The overall firmness is adjusted according to the amount of air inside the air bladder. If the user prefers a softer feel, less air is inflated, allowing the body to sink deeper.

[0016] 2. The protrusions and ventilation grooves on their lower surfaces not only increase the bonding area between the lower surface of the side seat cushion and the base, making the whole structure more secure, but also ensure the flatness of the upper surface of the side seat cushion while increasing breathability, reducing the possibility of dust falling inside.

[0017] 3. By using an elastic net with fabric strips along its edges, and with the support of pull ropes and rods passing through the base, the load-bearing capacity of the elastic net can be enhanced. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Reference Figure 1-6 A zero-gravity seat cushion with a heat dissipation and breathability structure includes a base 1 made of rigid sponge material, with enough rigidity to support the entire structure. The base 1 has a rectangular structure, and its upper surface has two longitudinal and parallel isolation grooves 2, which divide the upper surface of the base 1 into three equal parts, thus dividing the seating area. Custom proportions can also be made as required. On both sides of the two isolation grooves 2, there are recessed grooves 101 on the upper surface of the base 1, and each recessed groove 101 contains an inflatable bladder 9. A central groove 105 is formed in the middle of the upper surface of the base 1 between the two isolation grooves 2, and an elastic mesh 12 is installed within the central groove 105. The bottom of the base 1 is located between the two recessed grooves 101. 01 has a cylindrical groove 102 at the bottom, and the bottom of the cylindrical groove 102 has a concentric circular hole 103 that communicates with the inside of the base 1; the upper surface of the base 1 is attached to the top of the two grooves 101 with a side cushion 4 by sponge adhesive, and the upper surface of the base 1 is attached to the middle groove 105 with a middle pad 5. Both the side cushion 4 and the middle pad 5 are made of soft sponge material; the base 1 with an inflatable bladder 9 inside allows the user to first feel the soft side cushion 4 when sitting lightly, and then press on the inflatable bladder 9 as the whole body sinks. The overall hardness is adjusted according to the amount of air inside the inflatable bladder 9. If the user prefers a softer feel, less air is inflated so that the whole body can sink deeper.

[0027] In this invention, the lower surfaces of the two side cushions 4 have the same shape, and the lower surface of the side cushion 4 has a protrusion 402 whose shape matches the opening size of the top of the recess 101. The lower surface of the protrusion 402 has ventilation grooves 401 distributed at equal intervals. The depth of the ventilation grooves 401 is less than the overall thickness of the side cushion 4, that is, there are no holes in the upper surface of the side cushion 4. This not only increases the bonding area between the lower surface of the side cushion 4 and the base 1, making the whole structure more solid, but also ensures the flatness of the upper surface of the side cushion 4 while increasing breathability, reducing the possibility of dust falling into it.

[0028] The upper surface of the middle pad 5 of the side seat cushion 4 is designed in a wavy, undulating shape, and there is a gap between the side seat cushion 4 and the middle pad 5. The gap is located directly above the isolation groove 2, which makes it easy to distinguish each seat and reduce the mutual influence between them.

[0029] Please refer to Figure 4 The elastic net 12 has fabric strips 15 sewn along its edges, and pull cords are fixed at equal intervals on the opposite edges of the elastic net 12. The ends of the pull cords on both sides that are away from the elastic net 12 pass through the middle partition of the base 1 and are fixed with pull rods 16. With the elastic net 12 with fabric strips 15, and the pull cords and pull rods 16 passing through the base 1, the load-bearing capacity of the elastic net 12 can be enhanced.

[0030] The middle groove 105 has through holes 104 on both sides that communicate with the sink 101, and two pull rods 16 are located above the through holes 104 on both sides respectively. When the airbags 9 on both sides are squeezed during use, the airflow can be squeezed into the middle groove 105 to increase the exhaust speed.

[0031] In this invention, a down bag is placed at the bottom of the middle groove 105, and the top of the down bag abuts against the lower surface of the elastic net 12; thus improving the softness of the middle position.

[0032] The four vertical edges of the base 1 are rounded with corners 6, and the four edges of the base 1, side cushions 4 and middle cushions 5 are smoothed after assembly to ensure that the rounded corners 6 of the four edges can overlap, which facilitates the later leather wrapping process.

[0033] Reference Figure 6 Spring ropes 18 are fixed at all four corners of the airbag 9, and anti-detachment caps 8 are fixed at the front and rear sides of the base 1 through the spring ropes 18. The anti-detachment caps 8 ensure that the airbag 9 is always in the middle position inside the base 1.

[0034] The base 1 has a strip groove 3 and an arc groove 10 on its front and rear sides, respectively, which are opposite to the positions of the spring ropes 18. Both ends of the strip groove 3 and the arc groove 10 have stepped holes 106. The four spring ropes 18 on the same airbag 9 pass through the four stepped holes 106 respectively. The diameter of the stepped holes 106 is smaller than the diameter of the anti-slip caps 8. Straight locking plates 7 and arc locking plates 11 are respectively engaged in the strip groove 3 and the arc groove 10. Both ends of the straight locking plates 7 and the arc locking plates 11 have anti-slip notches 17 that are adapted to the diameter of the spring ropes 18. During installation, the four anti-slip caps 8 on the outer wall of the airbag 9 can be tightly fixed to the outside of the base 1.

[0035] The air bag 9 has an inflation nozzle 13 on the side near the arc groove 10, and the outer wall of the inflation nozzle 13 is fitted with an anti-detachment ring 14 embedded in the base 1; the air volume of the air bag 9 can be adjusted from the outside through the anti-detachment ring 14.

[0036] During installation, first, place the inflatable bladder 9 with four spring ropes 18 into the recesses 101 on both sides of the base 1. Then, pull out the spring ropes 18 with anti-slip caps 8 from the stepped holes 106 on the front and rear sides of the base 1. Next, use the straight clamping plate 7 and the arc-shaped clamping plate 11 to hold the spring ropes 18 in place, thus fixing the four anti-slip caps 8 to the outside of the base 1. Then, place the down bag in the middle groove 105. Then, pass the pull ropes on both sides of the elastic net 12 through the two partitions in the middle of the base 1 and fix them with the pull rod 16. Next, apply sponge glue to the lower surfaces of the side cushion 4 and the middle cushion 5 and stick them to the base 1. Finally, after the sponge glue has dried, inflate the inflatable bladder 9 according to the factory requirements.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
