Description

Multiple zone pressure adjustable airbag seat cushion

The invention relates to a seat cushion, in particular to a multi-zone pressure-adjustable airbag seat cushion that can manually or automatically adjust a plurality of softness and hardness combinations in different areas of the seat cushion.

Modern people often sit for long periods of time, which can easily cause long-term pressure on the buttocks, resulting in poor blood circulation, affecting health and even leading to disease. Therefore, there are airbag seat cushions on the market to relieve the discomfort caused by long-term sitting. However, such airbag seat cushions usually adopt a fully connected method, that is, all airbags are inflated from a single air inlet, resulting in the air pressure of all airbags to be equal, that is, the hardness of all airbags is the same. In this way, when the user sits down, the conventional airbag seat cushion cannot provide different hardness for different parts of the buttocks (such as the coccyx or hemorrhoids), so that the user cannot adjust to the most comfortable state.

In view of this, the author has accumulated many years of research and practical experience in related fields and has created a multi-zone pressure-adjustable airbag seat cushion to improve the deficiencies of the above-mentioned known technology.

The main purpose of this invention is to provide a multi-zone pressure-adjustable airbag seat cushion, which divides the airbag into multiple parts, allowing the user to adjust the hardness of the airbag in different parts, and can combine the inflation unit with the air pressure control element to set the upper and lower limits of the air pressure and automatically start the inflation unit to replenish the air pressure when the air pressure is insufficient, and can also have a low pressure warning function.

To achieve the above-mentioned purpose, the invention provides a multi-zone pressure-adjustable airbag seat cushion, comprising an airbag component, which is a sheet material with a plurality of airbags convexly arranged on the top surface, each of which has a first spacer, and the airbag component has a first inflation port, a first connecting air port and a second connecting air port, the first inflation port, the first connecting air port and the second connecting air port are respectively connected to one of the airbags, and has a plurality of first connecting grooves and a plurality of second connecting grooves. The grooves are respectively recessed in the first spacing parts of the parts, so that the airbags of some parts are connected by the first connecting grooves and the airbags of another part are connected by the second connecting grooves, the first inflation port and one of the first connecting air ports are respectively arranged in one of the airbags connected by the first connecting grooves, and the second connecting air port is arranged in one of the airbags connected by the second connecting grooves; and a bottom component, which is a sheet of material, and the bottom component is combined with the bottom end of the airbag component.

Each airbag of the invention is connected through the first connecting groove or the second connecting groove, so it can be divided into two areas. Each second connecting groove can be arranged on one side (e.g., the left side) of the airbag component, and each first connecting groove is arranged on the other side (e.g., the right side) of the airbag component, so that the air pressure of the airbag connected to each second connecting groove can be adjusted to be different from that of the airbag connected to each first connecting groove.

The invention may further include a first connecting valve, the two ends of which are respectively connected to the first connecting air port and the second connecting air port in an airtight manner. The first connecting valve selectively connects or blocks the first connecting air port and the second connecting air port, allowing the user to manually adjust the air pressure difference on both sides. The first air inlet may be provided with an air valve; each air valve may be connected to an air inlet unit, which includes an air pressure control element for automatically controlling the air pressure of each air bag. The air pressure control element may automatically open and close the air inlet unit according to the upper and lower limits of air pressure set by the user, and automatically start the air inlet unit to replenish the air pressure when the air pressure is insufficient, thereby improving the accuracy of the air pressure and the comfort of the invention, and may further provide a low pressure detection element to remind the user when the air pressure of the invention is too low. The first vent and the second vent may also be connected to an air inlet unit respectively to control the air pressure on both sides respectively.

The cross-section of each airbag and each joint can be rectangular. The airbags can be arranged in a chessboard pattern on the airbag component. The airbag component and the bottom component can be made of sheet material made of neoprene-CR, which is waterproof, pressure-resistant, heat-resistant, elastic, soft, and has a delicate feel; or made of natural rubber (NR), polyvinyl chloride (PVC), neoprene (CR), polyurethane (PU) or other rubber materials.

In another embodiment, the airbag component further has a third connecting vent and a fourth connecting vent, the third connecting vent and the fourth connecting vent are connected to one of the airbags respectively, and further has a plurality of third connecting grooves recessed in part of each first partition, so that another part of each airbag is connected by each third connecting groove, the third connecting vent is set in one of the airbags connected by each first connecting groove, and the fourth connecting vent is set in one of the airbags connected by each third connecting groove. This allows the invention to be divided into three areas of different hardness according to the parts connected by each first connecting groove, each second connecting groove, and each third connecting groove, and the invention can be divided into more areas by analogy.

Each third connecting groove can be arranged at each first spaced portion at the center of one side of the airbag component, each first connecting groove can be arranged at each first spaced portion at one side of the remaining portion of the bottom component, and each second connecting groove can be arranged at each first spaced portion at the other side of the remaining portion of the bottom component. A second connecting valve can be provided, and its two ends are respectively connected to the third connecting vent and the fourth connecting vent, and the second connecting valve selectively connects or blocks the third connecting vent and the fourth connecting vent.

In order to clearly and fully disclose the present invention, a diagram of a preferred implementation is provided to explain the implementation method in detail as described below.

Please refer to the first to third figures, which disclose the diagrams of the implementation method of the present invention. The above figures illustrate the implementation example (I) of the multiple zone pressure adjustable airbag seat cushion 1 of the present invention, which includes an airbag component 11, which is a sheet material with multiple airbags 111 convexly arranged on the top surface, and a first spacer 112 is respectively provided between each airbag 111. The airbag component 11 has a first inflation port 113, a first connecting air vent 114 and a second connecting air vent 116. The first inflation port 113, the first connecting air vent 114 and the second connecting air vent 116 are respectively connected to one of the airbags 111, and have a plurality of first connecting grooves 1121 and a plurality of second connecting grooves. 1122 are respectively recessed in part of each first spacing portion 112, so that part of the airbags 111 are connected by the first connecting grooves 1121 and the other part of the airbags 111 are connected by the second connecting grooves 1122, that is, the airbag component 11 is divided into two areas that are not connected to each other, the first inflation port 113 and one of the first connecting air ports 114 are respectively arranged in one of the airbags 111 connected by the first connecting grooves 1121, and the second connecting air port 116 is arranged in one of the airbags 111 connected by the second connecting grooves 1122; and a bottom component 12, which is a sheet of material, and the bottom component 12 is combined with the bottom end of the airbag component 11.

In the embodiment (I), the first inflation port 113 is provided with an air valve 115 to prevent the gas inside each air bag 111 from leaking. The air valve 115 is further connected to an inflation unit 2. The inflation unit 2 includes an air pressure control element 21 and a low pressure detection element 22. The air pressure control element 21 is used to automatically control the air pressure inside each air bag 111, and automatically adjusts according to the upper and lower limits of the air pressure set by the user. The low pressure detection element 22 is used to remind the user of the situation where the air pressure is too low. The embodiment (I) also has a first connecting valve 3, whose two ends are respectively airtightly connected to the first connecting air port 114 and the second connecting air port 116. The first connecting valve 3 selectively connects or blocks the first connecting air port 114 and the second connecting air port 116.

In the embodiment (I), the airbag component 11, the airbag 111 and the bottom component 12 are all square, but the present invention is not limited to the shapes of the airbag component 11, the airbag 111 and the bottom component 12. The cross-section of each airbag 111 is rectangular, and each airbag 111 is arranged in a checkerboard manner on the airbag part 11. Each airbag 111 is arranged in a 9-by-8 pattern. Four airbags 111 in the center row of nine rows of airbags 111 are connected to the left half, and the other four are connected to the right half. However, the present invention does not limit the number and arrangement of each airbag 111. For example, each airbag 111 may also be arranged in an 8-by-8 pattern. The number of airbags 111 in the present invention is large and dense, so that each airbag 111 has more independent contact points, which enhances the pressure dispersion ability, increases the fit and conformability, and significantly improves the pressure relief ability and comfort level. The arrangement of the present invention can be divided into left-right or front-back arrangements according to needs.

Each first connecting groove 1121 and each second connecting groove 1122 of the invention is a flat air flow channel, so that when the invention is subjected to local force applied by the user, the air flow between the airbags 111 can flow smoothly, thereby improving the stability of use; the invention also has the ability to buffer the reaction force to protect the user. Each second connecting groove 1122 can be arranged on one side of the airbag component 11. In the third figure, it can be seen that the airbag 111 connected to each second connecting groove 1122 in embodiment (I) is the left half, and each first connecting groove 1121 is arranged on the right half of the airbag component 11. In this way, the air pressure of the airbag 111 connected to each second connecting groove 1122 can be adjusted to be different from the airbag 111 connected to each first connecting groove 1121. The user can open the first connecting valve 3, let the airbag 111 connected to each second connecting groove 1122 be inflated to a suitable hardness, and then close the first connecting valve 3 to maintain the air pressure, and then adjust the airbag 111 connected to each first connecting groove 1121.

Each airbag 111 of the invention has multiple independent shapes. The space between each airbag 111 can increase airflow and circulation, reduce heat flow, and make the user feel cooler and less stuffy. The top of each airbag 111 can be flatter, which is more comfortable to use.

In the present embodiment (I), the air pump unit 2 includes an air pressure control element 21 and a low pressure detection element 22. The air pressure control element 21 can automatically open and close the air pump unit 2 according to the upper and lower limits of the air pressure set by the user, and automatically start the air pump unit 2 to replenish the air pressure when the air pressure is insufficient, thereby improving the accuracy of the air pressure and the comfort of the invention. A low pressure detection element 22 can be further provided to remind the user to check whether the air pump unit 2 is faulty or leaking when the air pressure of the invention is too low, and each unconnected area can have an independent low pressure detection element 22. The invention can also use a manual air pump 2, such as a handheld air pump, which is simple and effortless to operate. In the first embodiment, the first inflation port 113 is disposed at a 45-degree angle of the airbag member 11, which increases the convenience of adjustment and reduces the probability of the air valve 115 being squeezed against the seat frame.

As can be seen in the fourth figure, air enters one airbag 111 from the first inflation port 113 (omitted in the figure) and then flows to the remaining airbags 111 through the first connecting groove 1121. The air enters each airbag 111 connected by each second connecting groove 1122 from the second connecting port 116 after passing through the first connecting valve 3 from the first connecting port 114. The first connecting valve 3 can be a 90-degree rotary switch for switching between intercommunication and non-intercommunication. Considering intuitive control, simple operation and small size, metal materials are selected to increase airtightness and durability; in embodiment (I), the first connecting valve 3 has a 6mm long cross diagonal design at the rotating part, which is easy to hold to adjust the hardness of each airbag 111.

The airbag component 11 and the bottom component 12 can be made of sheet materials made of neoprene-CR, which is waterproof, pressure-resistant, heat-resistant, elastic, soft, and has a delicate feel. The airbag component 11 and the bottom component 12 can also be made of natural rubber (NR), polyvinyl chloride (PVC), chloroprene rubber (CR), polyurethane (PU) or other rubber materials or other materials. When using this creation, the user can also put on a protective cover of different materials according to the user's preference. For example, the upper layer of the protective cover can be made of breathable four-way high-elastic Nylon cloth, which fits the surface of each airbag 111 to increase conformability and breathability. The lower layer is an excellent anti-slip layer to reduce the risk of the user slipping with this creation. The two sides of the protective cover can also have handles to assist in shifting and carrying. Example (I) has passed the REACH/SVHC content survey table and does not contain substances of high concern that are harmful to humans.

As can be seen in the fifth figure, each second connecting groove 1122 in the embodiment (I) corresponds to the user's left buttocks, and each first connecting groove 1121 corresponds to the right buttocks. When the user sits on the embodiment (I), the left and right buttocks can receive different support forces. The air pressure in each second connecting groove 1122 in the fifth figure is lower than that in each first connecting groove 1121, so each air bag 111 on the left is softer, and users with different needs can adjust the softness and hardness of different areas. This creation can help improve the tilted and incorrect sitting posture, and there is the convenience of not having to get up and down when adjusting. This creation can be used when the body part needs to release pressure and reduce pressure and increase the comfort when sitting.

In the sixth figure, in the embodiment (two) of the present invention, the multiple-zone pressure-adjustable airbag seat cushion 1 is divided into three zones to respectively correspond to the left and right buttocks and the central coccyx zone of the user, so the airbag component 11 further has a third connecting vent 117 and a fourth connecting vent 118, the third connecting vent 117 and the fourth connecting vent 118 are respectively connected to one of the airbags 111, and further have a plurality of third connecting grooves 1123 recessed in part of each first spacing portion 112, so that another part of each airbag 111 is connected to each third connecting groove 1123, the third connecting vent 117 is provided in one of the airbags 111 connected to each first connecting groove 1121, and the fourth connecting vent 118 is provided in one of the airbags 111 connected to each third connecting groove 1123. There is also a second connecting valve 4 , whose two ends are respectively connected to the third connecting vent 117 and the fourth connecting vent 118 , and the second connecting valve 4 selectively connects or blocks the third connecting vent 117 and the fourth connecting vent 118 .

In the second embodiment, the central coccyx area of the user is further separated, so each third communication groove 1123 is provided at each first partition portion 112 at the center of one side of the airbag component 11 (the center of the upper side in the seventh figure), each first communication groove 1121 is provided at each first partition portion 112 at one side of the remaining part of the airbag component 11 (the right side in the sixth figure), and each second communication groove 1122 is provided at each first partition portion 112 at the other side of the remaining part of the airbag component 11 (the left side in the sixth figure).

When using embodiment (two), the user can open one of the first connecting valve 3 or the second connecting valve 4, and after the airbags 111 connected to each second connecting groove 1122 or the airbags 111 connected to each third connecting groove 1123 are inflated to a suitable hardness, the first connecting valve 3 or the second connecting valve 4 is closed to maintain the air pressure, and then the airbags 111 connected to each third connecting groove 1123 or the airbags 111 connected to each second connecting groove 1122 are adjusted, and finally the airbags 111 connected to each first connecting groove 1121 are adjusted.

This article discloses embodiments of dividing the invention into two areas and three areas, but the invention can be divided into four or more areas by adding more connecting vents, connecting valves and spacer grooves.

As can be seen in FIG. 7, the invention can be connected in parallel in multiple numbers to form an airbag mattress. FIG. 7 uses eight embodiments (I) of the invention, and each first air vent 114 and each second air vent 116 can be connected to an inflation unit 2 respectively. FIG. 7 shows an inflation module 23 including two inflation units 2 to respectively connect each first air vent 114 or each second air vent 116 of different multiple-zone pressure-adjustable airbag cushions 1. That is, the air pressure in the upper half and the air pressure in the lower half of all the multiple-zone pressure-adjustable airbag cushions 1 can be adjusted at the same time, so that the airbag mattress connected in parallel by the invention can automatically change the air pressure and hardness of different areas, thereby reducing the chance of bedsores for users who lie down for a long time.

However, what is described above is only the best implementation example of this creation and should not be used to limit the scope of implementation of this creation. Any changes and modifications that are obviously possible for people familiar with this industry should be considered as not deviating from the essential content of this creation.
