Description
Technical Field
The invention relates to the field of cushions, in particular to a pelvis cushion.
Background
People who need to sit on a chair for a long time are increasing, such as office workers and students. Technical ideas to prevent various side effects and diseases due to wrong postures and to help maintain a comfortable seated state are well known.
Most of the conventional cushions (seat cushions) are widely used in a form in which a user naturally takes a posture when seated by forming a certain degree of curvature according to the pelvis or buttocks of the user only by the shape of the seat cushion.
On the basis of this, a technical idea of using a new material such as memory sponge and latex, that is, further using material characteristics, has been used.
However, in consideration of the situation in which a cushion or a cushion is pressed by the weight of a user after the user sits, the desired effect cannot be achieved by using only a cushion or a cushion made of one material of memory foam or latex.
For example, when a memory sponge material having a high viscosity is used, it has an excellent restoring force to its original shape after being pressed, but the shape is easily deformed even by a low pressure due to insufficient supporting force, and thus it is not enough to adjust the sitting posture of the user.
When the latex material is used, the elasticity is strong, but the strong elasticity of the latex material may cause irritation to the skin of the user, and may not be suitable for various body shapes of the user.
Therefore, there is a need for a pelvic cushion that promotes a user to feel comfortable and easily adjust the user's correct posture by using a cushion body made of a material having comfortable cushioning and excellent restitution force, such as memory sponge, and a support member mechanism made of a gel structure satisfying both viscosity and elasticity.

The seat cushion body 100 includes a protrusion 140 formed at a front center portion of the receiver 110 of the seat cushion body 100 so as to be positioned between thighs of a seated user.
The invention will be further described with reference to the accompanying drawings, in which:
as shown in fig. 1 and 2, the pelvic seat cushion according to the preferred embodiment of the present invention includes a cushion body 100 having both sides curved upward to wrap the buttocks of a user when the user is seated, and a support member mechanism 200 having viscosity and elasticity and mounted to the receiver 110 of the cushion body 100 to distribute pressure.
According to a preferred embodiment of the present invention, the support member mechanism 200 includes a first support member 210 and a second support member 220, and the first support member 210 and the second support member 220 are respectively attached to the support portions 110 on both left and right sides around the center portion of the seat cushion body 100.
According to a preferred embodiment of the present invention, the seat cushion body 100 may be formed of a memory sponge. The memory sponge is a material developed by the American aerospace agency for buffering the impact on astronauts when launching space shuttles, has a restoring force, and can slowly recover the original form after pressure is applied. Therefore, the cushion body 100 can appropriately disperse the pressure generated by the buttocks of the user by the restoring force of the user when the user sits on the seat. Of course, the scope of the present invention is not limited thereto, and the seat cushion body 100 may be formed of the memory sponge, or may be formed of various materials having appropriate restoring force. For example, the seat pad body 100 may be formed of the memory sponge or latex.
The center of the seat body 100 is formed with a groove 120 facing the leg of the user when the user sits thereon.
According to a preferred embodiment, as shown in fig. 1, the groove 120 is formed in a semicircular shape elongated in a direction of the leg of the user by a predetermined length.
When the recess 120 is formed in the seat cushion body 100, the recess 120 functions as a space formed by the seat cushion body 100 being pressed toward the center of the seat cushion body 100 when the seat cushion body 100 is pressurized by a user sitting thereon, and thus can serve as a cushion.
Therefore, the groove 120 can function to prevent the occurrence of cracks due to the cushion body 100 being pressed or twisted by the pressure applied to the cushion body 100.
Meanwhile, the groove 120 also has a function of preventing a cushion cover (not shown) wrapping the cushion body 100 and/or the support member mechanism 200 from being indented or wrinkled to some extent.
According to a preferred embodiment, the seat cushion body 100 includes a support portion 130 formed to extend in an upward direction from a rear side thereof to support a portion of the user's spine.
The support portion 130 is formed to allow the user to sit comfortably by wrapping a part of the buttocks and/or thighs according to the shape of the cushion body 100 when the user sits on the pelvic cushion, and to support a part of the user's spine in a state where the user sits so as to help the user to sit in a proper posture in a comfortable state.
According to another preferred embodiment, the receiver 110 of the seat cushion body 100 may be formed with a plurality of vent holes 111 vertically penetrating the seat cushion body 100.
The plurality of vent holes 111 not only improve the ventilation of the pelvic cushion to make the seating more comfortable, but also expect the effect of dispersing the pressure applied to the cushion body 100, such as the grooves 120.
The plurality of ventilation holes 111 may be formed in various numbers as needed, and are preferably formed to be evenly distributed in the support portion 110 of the seat cushion body 100.
According to another preferred embodiment, the front center portion of the receiver 110 of the seat cushion body 100 may be formed with a protrusion 140 so as to be positioned in the middle of the thighs of the seated user.
The projections 140, as previously described, are positioned between the user's thighs when the user is seated, facilitating the user to find the thighs and maintain a correct sitting position while using the pelvic cushion.
The protruding portion 140 is made of the same material as the seat cushion body 100 and is formed integrally with the seat cushion body 100 by extending from the support portion 110 of the seat cushion body 100.
As shown in fig. 1, one end of the groove 120 is adjacent to the protrusion 140, and the other end of the groove 120 is adjacent to a certain range of the rear surface of the seat cushion body 100, and the support part 110 of the seat cushion body 100 is divided into left and right sides according to the groove 120. On the left and right sides of the receiving portion 110 of the divided seat cushion body 100, the user can place the left and right buttocks, respectively.
As described above, according to the pelvic seat cushion according to the technical idea of the present invention, the support member mechanism 200 is formed on the support portion 110 of the seat cushion body 100.
As shown in fig. 2, the support member mechanism 200 may be composed of a first support member 210 and a second support member 220 respectively installed on both left and right sides of the receiver 110 of the seat cushion body 100.
According to a preferred embodiment, the support member mechanism 200 may be formed of a gel structure having viscosity and elasticity. And the support member mechanism 200 acts as a leaf spring in the pelvic cushion, which acts to distribute pressure and ventilation when a user is seated. In addition, if the seat body 100 is formed of a memory sponge material, a user may feel excessive softness due to the characteristics of the memory sponge when seated on the seat body 100, and the support member mechanism 200 may slightly control such excessive softness and more stably support the buttocks of the user.
In addition, the first and second supporting members 210 and 220 may be disposed such that a portion of adjacent sides (e.g., 211, 221) constitutes a covering portion of the groove 120 for covering the groove 120.
That is, as shown in fig. 2, when the first supporting member 210 and the second supporting member 220 are formed on the receiver 110 of the seat cushion body 100, a part of the adjacent side (e.g., the first supporting member edge 211 and the second supporting member edge 221) of the first supporting member 210 and the second supporting member 220 overlaps the groove 120. Accordingly, the first supporting member 210 and the second supporting member 220 are adjacent on the groove 120.
When the adjacent sides (e.g., the first supporting member edge 211 and the second supporting member edge 221) of the first supporting member 210 and the second supporting member 220 are disposed to cover the groove 120, it is possible to provide a supporting force to the space generated by the groove 120, and since the supporting member mechanism 200 is separated into the first supporting member 210 and the second supporting member 220, it is possible to have an effect of easily dispersing the pressure.
The support member mechanism 200 will be described in detail with reference to fig. 3 and 4.
Fig. 3 and 4 are schematic views for explaining a structure of a pelvic cushion according to a preferred embodiment of the present invention.
Fig. 3 and 4 show schematic structural views of the first support member 210 in the support member mechanism 200. For convenience of illustration, only the structure of the first support member 210 is illustrated, and those skilled in the art to which the present invention pertains can easily deduce that the second support member 220 also has the same structure as the first support member 210 to be described below.
According to a preferred embodiment of the present invention, the first supporting member 210 includes a first cushion portion 212 and a second cushion portion 213, and/or a reinforcing rib 214.
The first cushion portion 212 is formed by being divided by the first partition 2122 so that the first through holes 2121 penetrate in the front and rear of the regular hexagonal cross section. In addition, the first through holes 2121 are arranged in a hexagonal shape.
The thickness of the first spacer 2122 may be thinner toward the rear.
For example, the front end thickness of the first spacer 2122 may be set to 1.65 to 1.7mm, and the rear end thickness may be set to 1.55 to 1.6 mm.
Accordingly, the first through hole 2121 can be enlarged toward the rear, and the first mat portion 212 can be easily taken out of the mold when the first mat portion 212 is injection-molded. However, the front and rear ends or the thickness of the first spacer 2122 is too much different, the strength thereof is weakened, and thus the thickness difference should be set within a certain range.
The second mat portion 213 is formed by being divided by the second partition 2132 so that the second through holes 2131 penetrate in the front and rear of the regular hexagonal cross section. In addition, the second through holes 2131 are arranged in a hexagonal shape.
The thickness of the second partition 2132 may be thinner toward the front.
For example, the thickness of the second partition 2132 at the rear end may be set to 1.65 to 1.7mm, and the thickness at the front end may be set to 1.5 mm.
Accordingly, the second through hole 2131 can be enlarged toward the front, and the second mat portion 213 can be easily removed from the mold when the second mat portion 213 is injection molded.
In addition, the second barrier 2132 has a thinner thickness at the front end than at the rear end, thereby reducing the contact area with the user's spine and thus reducing the pressure. Also, however, the difference in thickness between the front and rear ends of the second barrier 2132 is too large, the strength thereof is weakened, and thus the difference in thickness should not exceed a certain range.
The second mat portion 213 may be stacked in front of the first mat portion 212 such that the respective centers of the second through holes 2131 coincide with the respective centers of the first through holes 2121. The second mat portion 213 and the first mat portion 212 may be integrally formed, and the first support member 210 has a 2-fold honeycomb (honey comb) structure through the second through holes 2131 and the first through holes 2121, thereby having air permeability and an effect of effectively dispersing pressure.
According to a preferred embodiment, the size of the second through hole 2131 and the first through hole 2121 is minimized within the injection molding possibility, and the pressure dispersion effect can be maximized. According to a preferred embodiment, the shortest width of each of the second through holes 2131 and the first through holes 2121 may be set to 10mm to 12mm, and the greatest depth of each of the second through holes 2131 and the first through holes 2121 may be set to 12mm to 14 mm.
In addition, the reinforcing rib 214 may be formed at a boundary area of each of the second through holes 2131 and the first through holes 2121. The reinforcing rib 214 may be formed around the boundary inside the second through hole 2131 connected with the first through hole 2121 while the second mat portion 213 is injection-molded.
According to another preferred embodiment, the reinforcing rib 214 may be formed around the boundary inside the first through-hole 2121 connected to the second through-hole 2131 while injection-molding the first mat part 212.
Each of the reinforcing ribs 214214 may support the second and first partitions 2132 and 2122 in a direction perpendicular to the second and first partitions 2132 and 2122, thereby reinforcing the first support member 210.
According to a preferred embodiment, each of the reinforcing ribs 214 may be formed in a structure in which 3 in-line ribs are cross-connected at the center. In addition, 6 ends of each of the reinforcing ribs 214 may be connected to 6 corners of the boundary area of the second and first partitions 2132 and 2122, respectively.
In this case, each of the reinforcing ribs 214 may be formed by 3 in-line ribs aligned in a direction perpendicular to the second and first partitions 2132 and 2122. Each of the reinforcing ribs 214 can thereby improve the supporting effect in the vertical direction for the second partition 2132 and the first partition 2122, thereby improving the durability of the first supporting member 210.
The width of each of the reinforcing ribs 214 may be set to be wider than the thickness of the second and first partitions 2132 and 2122. For example, the width of each reinforcing rib 214 may be set to 1.5 mm.
In addition, the composition of the viscoelastic material for preparing the first supporting member 210 may include a mixture of a copolymer of a polystyrene polymer and a polypropylene copolymer, and oil. The polystyrene polymer is a triblock (triblock) structure. The Polystyrene polymer may be styrene- (ethylene/butylene) -styrene Block Copolymer (SEBS) or styrene-ethylene-propylene Block Copolymer (SEEPS). Thus the copolymer of polystyrene polymer and polypropylene copolymer may be PP-SEBS.
The mixture may contain 30 to 40 wt% of a copolymer of a polystyrene polymer and a polypropylene copolymer, and 60 to 70 wt% of an oil. At this time, when the content of the oil is less than 60% by weight, the hardness (Shore A) increases, the effect of controlling dispersion decreases, the shrinkage ratio is large, and ejection (ejection) at the time of injection is difficult, and when it exceeds 70% by weight, the oil is not easily mixed with the co-polymer, injection is impossible, and even if injection is completed, oil injection occurs at the time of use, so the oil content should be set in the above range.
The composition may include 5 to 8 wt% of an additive based on 100 wt% of a mixture consisting of the copolymer and the oil. In this case, if the content of the additive is less than 5% by weight, the oil and the copolymer cannot be mixed and the physical properties are deteriorated, and if it exceeds 8% by weight, the hardness is increased, so that the additive should be added in the above-mentioned content range. The additive is used to remove oil spray and improve heat resistance, and dry silica or wet silica may be used. As the dry Silica, Fumed Silica (fused Silica) can be used.
The composition may further contain a heat stabilizer as necessary to prevent the composition from being heated by heating during molding. In this case, the composition may include 0.3 to 0.7 wt% of a heat stabilizer based on 100 wt% of a mixture composed of the copolymer and the oil.
The heat stabilizer may be composed of organic phosphites such as triphenyl phosphite, tris- (2, 6-dimethylphenyl) phosphorous acid, tris- (mixed mono-and di-nonylphenyl) phosphorous acid, or phosphonic acid esters such as dimethyl phenylphosphonate, or phosphoric acid esters such as trimethyl phosphate, or may be composed of a combination thereof.
The composition may include 0.5 to 5.0 wt% of aromatic oil and 0.05 to 10.0 wt% of antibacterial agent based on 100 wt% of a mixture consisting of the copolymer and the oil, and may have aromatherapy and antibacterial functions.
If the content of the aromatic oil is less than 0.5% by weight, the effect of aromatherapy cannot be achieved, and if it is more than 5% by weight, the physical properties of the composition are reduced. The aromatic oil is extracted from at least one selected from lavender, grapefruit, eucalyptus, rosemary, peppermint, and YLANG-YLANG (YLANG-YLANG) group.
If the content of the antibacterial agent is less than 0.05% by weight, the antibacterial activity value is less than 2, and the antibacterial effect cannot be exhibited, and if it is more than 10% by weight, problems such as generation of bubbles, deterioration of physical properties, inability to mold, or inability to measure may occur during the production process. The antibacterial agent may be an organic antibacterial agent or an inorganic antibacterial agent. The organic antimicrobial agent may be Zinc pyrithione (Zinc bis: 2-pyridineethiol-1-oxide).
As described above, the pelvic seat according to the technical idea of the present invention may be provided with a cushion cover (not shown in the drawings) that entirely covers the seat body 100 and the support member mechanism 200. The cushion cover (not shown in the figures) can be designed to be easily detachable or sleeved. Meanwhile, the cushion cover (not shown) can cover and protect the cushion body 100 and the support member mechanism 200, and when washing is required, the cushion cover (not shown) can be detached, so that washing can be simply and conveniently completed.
According to a preferred embodiment, in order to maximize the air permeability of the cushion cover (not shown in the drawings), at least a portion corresponding to the support portion 110 of the cushion body 100 may be designed as a mesh fabric. In this way, while preventing body fluid such as sweat discharged when a user sits on the seat cushion body 100 and/or the support member mechanism 200 from coming into direct contact with them, the user can be provided with comfort.
The present invention has been described in terms of preferred embodiments in the drawings, but these are merely exemplary, and it will be appreciated by those of ordinary skill in the art that many variations or equivalents of the preferred embodiments are possible.
