Description

Pelvis pad

The invention relates to a cushion for supporting a user's pelvis when the user is seated.

Traditional cushions such as cushions are often used to support the user's pelvis when the user is seated. Such cushions should have appropriate flexibility, compressibility, shock absorption, dehumidification, deformation tracking and durability, so that users can feel comfortable even if they sit for a long time. For this reason, existing seat cushions mainly use cotton, sponge, polyurethane foam, rubber, etc. as internal filling materials.

For example, a cotton seat cushion provides a comfortable and soft sitting sensation by absorbing impact. The reason is that the fiber structure of cotton forms a net shape, and continuously supplies air to the cotton to produce a restoring force. However, the cotton pad should use a large amount of cotton to give a good sitting feeling, and it will become thin after long-term use, which is easy to reduce the sitting feeling and breathability.

1 to 6, a pelvic cushion (100) according to an embodiment of the present invention includes a cushion body (110) and each cushioning member (120).

A hip support part (111) and a caudal vertebra support part (112) are formed on the seat cushion body (110), and are respectively used to support the hip bone and the caudal vertebra of the user's pelvis.

When the user is seated, the hip support portion (111) and the caudal vertebra support portion (112) support the hip bone and the caudal vertebra of the user's pelvis, so that the user can maintain a correct sitting posture even after sitting for a long time and feel comfortable. The pelvic height of ordinary adult men and women is 110mm±10mm, and the width of hip bone is 125mm±10mm. The hip support (111) and the tail support (112) can be ergonomically designed to reflect ordinary adulthood The shape and size of the male and female pelvic data. The maximum left and right width of the cushion body (110) is 45mm±5mm, the maximum front and rear length is 41mm±5mm, and the maximum height is 12mm±5mm. The cushion body (110) may have a flat underside.

A pair of slots (111a) into which the cushion members (120) are inserted from the upper portion may be provided on the upper surface of the hip support portion (111), respectively. The slots (111a) are spaced symmetrically. Each slot (111a) may be recessed at a certain depth above the hip support (111).

The hip support portion (111) may be formed into a shape in which the bottom surface of the socket (111a) is gradually recessed from the center of the hip support portion (111) to the left and right edges; and the front bottom surface of the socket (111a) is gradually recessed. Thereby, the hip support portion (111) can stably support the pelvis together with each cushion member (120). The hip support portion (111) may be formed such that the left and right walls on the left and right sides of the slot (111a) and the front wall have a certain width.

In addition, each bottom surface of each slot (111a) may be formed in a shape that supports each lower portion of the entire buffer member (120). The shape of the inner wall of the slot (111a) may be the same as the outer wall of the buffer member (120), so that the buffer member (120) can be inserted and coupled to each slot (111a). Thus, the lower portion and the outer wall of each cushion member (120) can be stably supported by each slot (111a).

The cushion body (110) may include a first vent hole (113) formed in the hip support (111) region between the cushion members (120). The first vent hole (113) removes the contact area with the important part of the user when the user is seated, reduces the pressure on the important part, and provides breathability. The first vent hole (113) penetrates up and down, and may have a certain left and right width. The first vent hole (113) may be formed into a curved shape in which the front and rear inner walls are recessed left and right.

Each slot (111a) may communicate with both sides of the first vent hole (113). Each slot (111a) may be formed in a shape that is cut to the bottom surface at a portion facing both sides of the first vent hole (113) so as to be connected to the first vent hole (113).

Each slot (111a) may be formed with a plurality of second vent holes (114), respectively. The second vent hole (114) may improve the air permeability together with each buffer member (120). The second vent holes (114) may be arranged at regular intervals. The second vent hole (114) may be formed as a regular hexagonal hole or a round hole. The second vent hole (114) can be formed in various sizes and numbers within a range capable of maintaining the durability of the seat cushion body (110).

The caudal vertebra support (112) extends into a shape that wraps a part of the user's rear hip from behind the hip support (111). The caudal vertebra support portion (112) may be formed into a shape in which the upper surface is gradually concave upward from the rear portion of the hip support portion (111) toward the rear. And, the caudal vertebra support portion (112) may be formed into a shape in which the rear portion gradually protrudes upward from the left and right toward the center.

For example, the cushion body (110) may be formed of a memory foam. Memory sponges are materials developed by NASA to cushion the impact of astronauts when launching a space shuttle. The memory foam has a restoring force that can slowly return to its original state after being pressed. Therefore, the cushion body (110) can properly disperse the pressure exerted by the pelvis as a whole through the restoring force of the memory foam. As another example, the cushion body (110) is made of latex material, and the pressure exerted by the pelvis can be appropriately dispersed as a whole by the restoring force of the latex.

A pair of cushioning members (120) are respectively inserted into the sockets of the hip support portion (111) on the hip support portion (111) with a set interval in the left-right direction of the hip support portion (111) and coupled to the hip support portion (111) (111a). Each cushioning member (120) can provide cushioning feeling to the left and right hip bones by dispersing pressure. Each buffer member (120) can achieve bilateral symmetry.

Each buffer member (120) is a viscoelastic material and has a plurality of through holes. That is, the buffer member (120) has viscosity and elasticity, and is formed as a through-hole structure. Therefore, when the user is seated, the cushioning member (120) can disperse the pressure applied to the pelvis, having a low critical pressure so as not to squeeze the skin and microvessels, thereby providing optimal comfort. In addition, for body heat and sweat generated when seated, the cushion member (120) can effectively distribute moisture and sweat through the air pump effect and excellent breathability of the through-hole structure, maintain temperature and humidity, and provide a refreshing sitting feeling.

In addition, the cushioning member (120) can improve the hip support (111) of the cushion body (110). That is, when the cushion body (110) is made of memory foam, the cushioning member (120) perfects the hip support portion (111) of the viscous cushion body (110), and maintains support with inherent elasticity. The effect of force and shape helps users maintain correct posture.

When the cushion body (110) is made of latex, the cushioning member (120) perfects the hip support (111) of the elastic cushion body (110) and reduces the contact area and pressure with inherent viscosity. This reduces irritation to the skin of the buttocks, making it easy to adapt to various body types.

The cushioning member (120) of the above structure is not glued to the slot (111a), but is physically inserted and joined, so the cushioning member (120) can be deformed independently of the hip support portion (111), thereby supporting the user's hip bone. Since each cushion member (120) and the surrounding hip support (111) are heterogeneous, it is possible to provide a massage function as the hip moves while maintaining a sitting posture.

The height of the upper edge of the buffer member (120) is the same as the upper edge of the socket (111a), so that the buffer member (120) can be inserted into the socket (111a) without a height difference. In addition, the height of the upper part of the buffer member (120) may be the same as the opening of the slot (111a). Of course, the upper edge of the buffer member (120) may be set higher or lower than the upper edge of the slot (111a) within the range capable of performing the above-mentioned functions.

For example, each cushion member (120) may include a lower cushion member (121), an upper cushion member (122), and a reinforcement rib (123).

The lower cushion (121) is divided and formed by the lower partition wall (121b) so that each of the lower through holes (121a) respectively penetrates up and down in a regular hexagonal cross section. Each lower through hole (121a) may be arranged in a hexagon.

The thickness of the lower partition wall (121b) may gradually become thinner toward the bottom. The lower partition wall (121b) can be set to have an upper end thickness of 1.65mm~1.7mm and a lower end thickness of about 1.55mm~1.6mm. As a result, the lower through hole (121a) gradually expands downward, so that when the lower cushion (121) is injection molded, the molded lower cushion (121) can be easily taken out of the mold. If the thickness difference between the upper end and the lower end is too large, the strength of the lower partition wall (121b) may become weak.

The upper buffer member (122) is divided and formed by the upper partition wall (122b), so that each upper through hole (122a) penetrates up and down in a regular hexagonal cross section. Each upper through hole (122a) may be arranged in a hexagon.

The thickness of the upper partition wall (122b) may gradually become thinner toward the upper side. The upper partition wall (122b) can be set to have a thickness of 1.65 mm to 1.7 mm at the lower end and a thickness of approximately 1.55 mm at the upper end. As a result, the upper through-hole (122a) gradually expands upward, so that when the upper cushion (122) is injection molded, the molded upper cushion (122) can be easily taken out of the mold. In addition, since the thickness of the upper end of the upper partition wall (122b) is gradually thinner than the thickness of the lower end, the area of contact with the hip bone of the user can be reduced, thereby reducing the pressure. If the thickness difference between the upper and lower ends is too large, the strength of the upper partition (122b) may become weaker.

The upper buffer (122) is stacked on the lower buffer (121) such that each center of each upper through hole (122a) coincides with each center of the lower through hole (121a). The upper buffer (122) may be integrally formed with the lower buffer (121). Therefore, the buffer member (120) adopts a double honeycomb structure through the upper through holes (122a) and the lower through holes (121a), which not only has air permeability, but also distributes pressure more effectively.

By minimizing the size of each upper through hole (122a) and lower through hole (121a) within the range of injection molding, the effect of dispersing pressure can be maximized. For example, the minimum width of each upper through hole (122a) and lower side through hole (121a) can be set to 10mm~12mm, and the maximum depth of each upper through hole (122a) and lower side through hole (121a) can be set to 12mm~14mm.

Each reinforcing rib (123) may be formed in a boundary area of each upper through hole (122a) and lower through hole (121a). Each reinforcing rib (123) can be molded together when injection molding the upper buffer (122), and formed around the boundary in the upper through hole (122a) connected to the lower through hole (121a). As another example, each reinforcing rib (123) may be molded together when injection-molding the lower cushion (121), and formed around the boundary in the lower through-hole (121a) connected to the upper through-hole (122a).

The reinforcing rib (123) supports the upper partition wall (122b) and the lower partition wall (121b) through the horizontal direction to reinforce the buffer member (120). The reinforcing rib (123) may be formed as a structure in which three in-line ribs are cross-connected at the center. The six ends of the reinforcing rib (123) may be connected to the six corners of the boundary area of the upper partition wall (122b) and the lower partition wall (121b), respectively.

That is, the three in-line ribs of the reinforcement rib (123) are aligned in the horizontal direction on the upper partition wall (122b) and the lower partition wall (121b), respectively. Thereby, the reinforcing rib (123) can further enhance the effect of supporting the upper partition wall (122b) and the lower partition wall (121b) in the horizontal direction, thereby improving the durability of the cushioning member (120). The width of each rib of the reinforcement rib (123) may be greater than the thickness of the upper partition wall (122b) and the lower partition wall (121b). The thickness of the reinforcing rib (123) can be set to 1.5mm.

The composition of the viscoelastic material used for preparing the cushioning member (120) may include a mixture composed of a copolymer of polystyrene polymer and polypropylene and oil. The polystyrene polymer has a triblock structure. The polystyrene polymer may be styrene-(ethylene/butene)-styrene block copolymer (SEBS, styrene-(ethylene/buthylene)-styrene block copolymer) or polystyrene-poly(ethylene-ethylene/propylene )-Polystyrene block copolymer (SEEPS, Polystyrene-block-poly(ethylene-ethylene/propylene)-blockpolystyrene). Therefore, the copolymer of polystyrene polymer and polypropylene may be PP-SEBS.

The mixture may contain 30 to 40% by weight of a copolymer of polystyrene polymer and polypropylene, and 60 to 70% by weight of oil. At this time, when the oil content is less than 60% by weight, the hardness (Shore A) increases, the dispersion control effect decreases, and the shrinkage rate is large, which makes it difficult to eject during injection. If it exceeds 70% by weight, the oil It is not easy to mix with the copolymer and cannot be injected. Even if the injection is completed, oil injection will occur during use, so the oil content should be set according to the above range.

The composition may be based on a mixture of polymer and oil 100% by weight, containing 5-8% by weight of additives. At this time, if the content of the additive is less than 5% by weight, the oil and the copolymer cannot be mixed, and the physical properties decrease. If it exceeds 8% by weight, the hardness increases, so the additive should be added according to the above content range. Additives are used to remove fuel injection and improve heat resistance. Dry silica or wet silica can be used. Fumed Silica can be used for dry silica.

The composition may also contain a heat stabilizer as needed to prevent heating due to heating during molding. At this time, the composition may be based on 100% by weight of the mixture composed of the copolymer and the oil, and contains 0.3 to 0.7% by weight of the heat stabilizer.

The thermal stabilizer can be composed of organic phosphites such as triphenyl phosphite, tri-(2,6-dimethylphenyl) phosphite, tri-(mono- and di-nonylphenyl) phosphite It may be composed of phosphate esters such as dimethyl phenylphosphonate or phosphate esters such as trimethyl phosphate, or may be composed of a combination thereof. The composition may be based on a mixture of copolymer and oil 100% by weight, containing 0.5 to 5.0% by weight of aromatic oil and 0.05 to 10.0% by weight of antibacterial agent, thereby having aroma healing and antibacterial functions.

If the content of the aromatic oil is less than 0.5% by weight, the effect of aroma healing cannot be achieved, and if it is more than 5.0% by weight, the physical properties of the composition are reduced. The aromatic oil can be extracted from at least any one selected from the group consisting of lavender, grapefruit, eucalyptus, rosemary, mint, and Ylang-Ylang.

If the content of the antibacterial agent is less than 0.05% by weight and the antibacterial activity value is less than 2, the antibacterial effect cannot be exerted. If it is more than 10.0% by weight, problems such as bubbles, reduced physical properties, inability to mold or unmeasured during the preparation process may occur. The antibacterial agent may be an organic antibacterial agent or an inorganic antibacterial agent. The organic antibacterial agent may be zinc pyrithione (Zincbis: 2-pyridinethiol-1-oxide).

In addition, the pelvic cushion (100) may further include a cushion cover (130) that wraps and covers the cushion body (110) and each cushion member (120). The cushion cover (130) can cover and protect the cushion body (110) and each cushion member (120). The size and shape of the cushion cover (130) may be set so that each cushioning member (120) does not disengage from a state of being inserted into each slot (111a) of the hip support portion (111). The cushion cover (130) may include a zipper (131) so that the cushion cover (130) can easily cover or detach from the cushion body (110).

In order to maximize the breathability of the cushion cover (130), in addition to the lower part, the upper part and the side parts can be formed on the mesh fabric. In this way, the cushion cover (130) on the one hand prevents sweat and body fluid discharged when the user sits down from directly contacting the cushion body (110) and each cushioning member (120), and on the other hand, can realize ventilation to provide comfort to the user.

In addition, the cushion cover (130) may be made of a fabric with elasticity and softness to help each cushion member (120) provide optimal pressure distribution. For example, the cushion cover (130) may be made of elastic (elastin) mesh or other fabric.

The present invention has been described according to an embodiment in the schematic diagram, but this is only an exemplary description, and a person of ordinary skill in the art can understand that there can be various other embodiments that are modified or equivalent. Therefore, the true technical protection scope of the present invention is limited only by the scope of the patent application.
