Description

cushion

The present invention relates to a seat cushion, and more particularly to an inflatable seat cushion.

Referring to Figures 1 and 2, a conventional medical inflatable cushion 1 includes a top layer 11, a bottom layer 12, and a plurality of air bags 13. The top layer 11 is attached to the bottom layer 12. The air cells 13 are arranged in an array and are disposed at intervals in the top layer 11. The airbags 13 are internally connected to each other, and each of the airbags 13 has a plurality of flanges 131 extending up and down. When the user sits on the seat cushion 1, the airbags 13 are subjected to different degrees of compression according to the user's hip shape, and the gas therein will flow to the airbag 13 with a lower degree of compression. Finally, the balance is reached, and the seat cushion 1 naturally becomes a shape conforming to the user's hip shape.

However, when the user moves the body to the left or right or changes the sitting posture, a lateral pushing force is generated because the folded edge 131 of the airbag 13 has no effect against the lateral pushing force, and thus it is easy to fall. When a part of the airbag 13 is tilted, a large gap is formed between the airbags 13, so that the airbag 13 is supported at some positions, and the other positions are not, the comfort of the ride is degraded, and there is room for further improvement.

Accordingly, it is an object of the present invention to provide a seat cushion that improves ride comfort.

Thus, the seat cushion of the present invention is suitable for use by a user, and the seat cushion includes a cushion body and an interlayer.

The pad body is constructed of a soft material, including a top layer, a bottom layer, and a plurality of air bags suitable for carrying a user. The top layer is attached to the bottom layer and includes a plurality of spaced apart openings. The airbags are respectively disposed in the openings. Each of the air bags includes a capsule that closes the corresponding opening, and at least one external thread formed on a peripheral surface of the outer surface of the capsule.

The interlayer is sandwiched between the top layer and the bottom layer of the mat and includes a plurality of ribs extending between adjacent two openings. Each of the ribs disengages the top layer and the bottom layer from each other to form a passage connecting the two adjacent openings.

The utility model has the advantages that the external thread can reinforce the lateral resistance of the airbag, and when the user moves the body to the left or right or changes the sitting posture, the airbags can resist the lateral force and avoid tilting, thereby ensuring each of the user's buttocks. The position has airbag support to improve the comfort of the ride.

Referring to Figures 3 and 4, a first embodiment of the seat cushion of the present invention is suitable for use by a user. The seat cushion includes a cushion body 2, a sandwich layer 3, and a gas nozzle 4.

Referring to Figures 4, 5 and 6, the pad 2 is constructed of a soft material, including a top layer 21, a bottom layer 22, and a plurality of air bags 23 suitable for carrying users. The top layer 21 is attached to the bottom layer 22 and includes a plurality of spaced apart openings 211. The air cells 23 are respectively disposed in the openings 211. Each air bag 23 includes a capsule 231 and three external threads 232. The capsule 231 closes the corresponding opening 211 and defines an air chamber 233 together with the opening 211. The external threads 232 are formed on the outer circumferential surface of the capsule 231 and are spaced apart from each other. Each external thread 232 extends from the top to the bottom of the capsule 231, and each external thread 232 is wound around the outer peripheral surface of the capsule 231. In this embodiment, the pad 2 is made of liquid latex.

It is worth mentioning that the number of the external threads 232 may also be one to two, or four or more, and depending on the number of threads, preferably about one to three turns around the outer peripheral surface of the capsule 231, when The smaller the number of the external threads 232, the higher the number of turns.

Referring to FIG. 4, FIG. 7 and FIG. 8, the interlayer 3 is sandwiched between the top layer 21 and the bottom layer 22, and includes a plurality of ribs 31 and a plurality of connecting blocks 32. Each of the ribs 31 extends between the adjacent two openings 211, and the top layer 21 and the bottom layer 22 are not overlapped with each other to form a channel 24 communicating with the adjacent two openings 211. Each channel 24 connects two adjacent gas chambers 233. The connecting blocks 32 are located in the openings 211 and connect the adjacent ribs 31. Preferably, only a portion of the openings 211 are provided with the ribs 31. In this embodiment, the openings 211 of the pad 2 are arranged in a 9 by 9 array, and the array is defined to have nine straight lines L11 to L19 and nine rows L21 to L29 which are vertically and horizontally staggered through the openings 211. . A part of the ribs 31 of the interlayer 3 is provided in an odd number of the straight lines L11, L13, L15, L17, L19, and another portion of the ribs 31 is provided in the courses L21 to L29. Since the ribs 31 are not disposed between each of the adjacent two openings 211, the number of the ribs 31 can be reduced, and the overall material and weight can be reduced.

The gas nozzle 4 is disposed in one of the air cells 23 and communicates to the corresponding air chamber 233 (see Fig. 5). Through the gas nozzle 4, the user can pump air into the cushion body 2, and the gas is filled into the respective gas chambers 233 through the passages 24. When the cushion body 2 is filled with too much gas, it can be vented by opening the gas nozzle 4, thereby adjusting the degree of inflation of the cushion body 2.

Referring to Fig. 3, Fig. 6, and Fig. 9, in use, air is first introduced through the nozzle 4, and gas is filled into the air chambers 233 of the cushion body 2 to expand the airbags 23 to a certain extent. When the user sits on the airbag 23, the airbag 23 at different positions will be squeezed to different degrees due to the individual hip type, pelvic position, etc., and the low position of the hip 9 is lower. The airbags 23 are squeezed to a large extent, and the gas therein is caused to flow through the passages 24 (see FIG. 8) into the airbags 23 located at a position higher than the height of the buttocks 9 and finally reach equilibrium. At this time, the position where the buttocks 9 is in contact with the cushion body 2 is almost the same, so that when the patient with the scoliosis or the pelvic cavity deforms uses the seat cushion of the present invention, the seat cushion is automatically adjusted to a shape suitable for the patient to ride. Allow patients to sit for a long time without feeling uncomfortable. Moreover, since the openings 211 are arranged in an array, the associated airbags 23 are also arranged in a corresponding array. Thus, the airbags 23 are spaced apart from each other and independent, and the external airflow easily flows through the gap between the airbags 23 to improve ventilation. The effect of heat dissipation enhances the comfort of the ride.

Referring to Figures 1 and 3, the conventional airbag 13 has only the flanges 131 extending up and down. When the airbags 13 are subjected to lateral forces, they are easily inclined, affecting the effect of the support. However, the airbags 23 of the present invention all have the external threads 232, which can reinforce the lateral supporting force. Therefore, it is possible to avoid the inclination of the capsules 231 due to the lateral force and improve the stability of the support.

In this way, the external threads 232 can reinforce the lateral resistance of the airbag 23, and when the user changes the sitting posture, the airbags 23 can resist the lateral force to avoid tilting, and ensure that the user's hips 9 have positions. The airbag 23 is supported to improve the comfort of the ride.

Referring to Figures 10 and 11, a second embodiment of the seat cushion of the present invention is substantially the same as the first embodiment except for the type of the airbag 23 and the interlayer 3.

Each of the outer threads 232 of each of the air cells 23 has two, and each of the external threads 232 extends from the top to the bottom of the capsule 231 and is wound around the outer circumferential surface of the capsule 231 by 1.5 turns. A part of the ribs 31 of the interlayer 3 is provided in an even number of the straight rows L12, L14, L16, L18, and another portion of the ribs 31 is provided in the rows L21 to L29.

Thus, the airbags 23 of the second embodiment also have the same lateral reinforcing effect as the first embodiment, and another design of the interlayer 3 is provided, and the user can adjust according to the needs thereof.

Referring to Fig. 12, a third embodiment of the seat cushion of the present invention is substantially the same as the first embodiment except that the outer thread 232 of each air bag 23 is one piece, and the external thread 232 extends from the top of the body 231. To the bottom, and around the outer peripheral surface of the capsule 231, 3 turns. As described above, the airbags 23 of the third embodiment also have the same lateral reinforcing effect as that of the first embodiment, and the user can adjust them according to their own needs.

In summary, the structural design of the airbags 23 can avoid tilting and affect the supporting effect. Therefore, the object of the present invention can be achieved.
