Description

Technical Field

[0001] The utility model belongs to the technical field of seat cushions, in particular to a corrective seat cushion. Background Art

[0002] With the increase in the number of office workers required for social work, long periods of sitting have become a label for this type of people, especially when using the wrong sitting posture during sitting. After a long time, it is not good for the spine of office workers, which leads to problems such as waist soreness and back pain. Therefore, a corrective cushion that can correct the sitting posture of office workers has appeared on the market. However, this type of cushion usually integrates the seat cushion part and the backrest part, which is not convenient for users to carry or store due to their large size. Some cushions adopt a plug-in structure to achieve split folding. This method not only makes it easy to separate the seat cushion part and the backrest part during transportation, but also requires reassembly when refolding. Therefore, there is a need for a corrective cushion that can open or fold the backrest part and the seat cushion part by rotation without the need for reassembly. Summary of the invention

[0006] Furthermore, an abutment seat is convexly provided at the rear end of the connecting portion, and both sides of the abutment seat protrude upward. When the limiting portion is inserted into the limiting groove, the lower surface of the protrusion abuts against the abutment seat, and at this time the abutment seat limits the protrusion from continuing to move downward.

[0007] Furthermore, positioning pieces are respectively provided on both sides of the protrusion. When the cushion piece and the backrest piece are in the open state, the positioning pieces abut against the protrusions on both sides of the abutment seat. When the cushion piece and the backrest piece are in the folded state, the positioning pieces abut against the inner wall of the rotating hole and limit the cushion piece from being pulled out.

[0008] Furthermore, the lower end of the backrest member extends backward to form a lower abutting end, and the rear end of the connecting portion extends backward to form an upper abutting end. When the backrest member and the cushion member are in an open state, the lower abutting end abuts against the upper abutting end.

[0009] Furthermore, the cushion member is also provided with a turntable assembly, and the turntable assembly includes a rotating member and a turntable base, the rotating member is installed on the turntable base, and a turntable mounting seat is provided on the lower surface of the cushion member, the turntable base is connected to the turntable installation and is arranged below the cushion member, and a guide groove is provided on the inner ring of the turntable mounting seat, the rotating member is adapted to the shape of the guide groove, and a plurality of rolling balls are provided on the rotating member, and the rolling balls are partially movably arranged in the guide groove. Rotating the cushion member can drive the turntable mounting seat to rotate relative to the rotating member.

A tool for users to correct their sitting posture. Most of the seat cushions on the market are usually of an integrated design in order to adapt to the chair, which makes it inconvenient for users to carry or store them due to their large size. In order to improve this situation, some seat cushions are made in a separable manner, that is, through a plug-in structure. The utility model does not need to separate the seat cushion part 1 and the backrest part 2, and supports folding and use through a method similar to a mortise and tenon structure. By opening a rotating hole 6, the user changes the direction in the rotating hole 6 through the protrusion 7 to achieve folding. When the backrest part 2 is inserted into the rotating hole 6 through the protrusion 7, the limiting part 9 is engaged with the limiting groove 10, and the backrest part 2 cannot move. If the user needs to fold and store it, he only needs to pull the backrest part 2 upwards. At this time, the limiting part 9 is disengaged from the limiting groove 10, and the user can control the backrest part 2 to rotate downward, and the protrusion 7 rotates in the rotating hole 6.

When the cushion member 1 and the backrest member 2 are in the open state, the positioning members 11 abut against the protrusions on both sides of the abutment seat 8. When the cushion member 1 and the backrest member 2 are in the folded state, the positioning members 11 abut against the inner wall of the rotating hole 6 and limit the cushion member 1 from being pulled out, so as to prevent the backrest member 2 from being pulled out and detached relative to the cushion member 1 when the backrest member 2 and the cushion member 1 are in the folded state. When in the folded state, the backrest member 2 is restricted from being pulled out by the positioning members 11, and the user does not need to reassemble it next time. When it needs to be used, the backrest member 2 is first pulled outward laterally, and the limiting portion 9 is separated from the contact with the limiting groove 10. At this time, the protrusion 7 can rotate in the rotating hole 6.

[0035] Preferably, the lower end of the backrest member 2 extends backward to form a lower abutting end, and the rear end of the connecting portion 3 extends backward to form an upper abutting end. When the backrest member 2 and the cushion member 1 are in an open state, the lower abutting end abuts against the upper abutting end. When in the open state, the lower connecting end 12 on the backrest member 2 and the upper connecting end 4 on the connecting portion 3 abut against each other to form a relative force.

[0036] Preferably, the seat cushion 1 is also provided with a turntable assembly, which includes a rotating member 15 and a turntable base 16, the rotating member 15 is installed on the turntable base 16, and a turntable mounting seat 14 is provided on the lower surface of the seat cushion 1, the turntable base 16 is connected to the turntable installation and is arranged below the seat cushion 1, and a hook platform is provided on the turntable base 16, and the turntable base 16 is connected with the hook part on the turntable mounting seat 14 through the hook platform to prevent the turntable base 16 from falling off. The inner ring of the turntable mounting seat 14 is provided with a guide groove 17, and the rotating member 15 is adapted to the shape of the guide groove 17, and a plurality of rolling balls 18 are provided on the rotating member 15, and the rolling balls 18 are partially movably arranged in the guide groove 17, and rotating the seat cushion 1 can drive The turntable mounting seat 14 rotates relative to the rotating member 15, which is convenient for some mothers with children to sit. Since they need to hold the child for a long time and if the child has just been coaxed to sleep, once the mother gets up to get something, the child is likely to wake up. The utility model arranges a turntable assembly on the lower surface of the cushion member 1, so that the user can turn the body to get things in other directions while sitting on the cushion without getting up, which is convenient for different groups of people to use and has better functionality. Through the built-in rolling ball 18, the user turns the body to drive the cushion member 1 to rotate together, and the cushion member 1 drives the turntable mounting seat 14 to move together. The turntable mounting seat 14 is provided with a guide groove 17, and the rolling ball 18 is in the guide groove 17, so the turntable mounting seat 14 can be rotated by the rolling ball 18.

[0037] Preferably, the turntable base 16 is also provided with the guide groove 17 , and the rolling ball 18 is partially disposed in the guide groove 17 .

[0038] Preferably, a boss 19 is also provided on the lower surface of the cushion member 1, and a plurality of anti-skid silica gels 20 are provided on the lower surface of the boss 19 and the lower surface of the turntable base 16 to increase friction and prevent the cushion from moving.
