Description

Technical Field

[0001] The utility model belongs to the technical field of waist protection cushions, and in particular relates to a waist protection cushion. Background Art

[0002] At present, for some people who sit for a long time, such as office workers or students, due to long-term work or study at a desk using a computer, the body is in a forward-leaning sitting position for a long time without waist and abdomen support, which is easy to cause waist and abdomen strain. The seats on the market require people to lean on the back of the chair to have a slight sense of support. If people do not lean back, change chairs or change postures, they will return to the phenomenon of hunching over. Although there is a waist cushion in the prior art, the waist backrest and cushion of this product are fixed together. When people swing their waist and abdomen back and forth for exercise, this waist backrest cannot always support the waist and abdomen, and cannot play a role in auxiliary support for exercise. Utility Model Content

[0003] The utility model provides a waist protection seat cushion, aiming to solve the problem in the prior art that the waist protection seat cushion cannot always support the waist and abdomen when a person's waist and abdomen swing back and forth for exercise, resulting in failure to play a role in auxiliary support for exercise because the waist protection backrest and the seat cushion are fixed together.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A waist protection cushion, comprising:

[0006] A seat cushion, provided with a seat cushion hinge;

[0007] A lumbar support backrest is provided with a backrest hinge portion rotatably connected to the seat cushion hinge portion; and,

[0008] A torsion spring is arranged between the seat cushion hinge part and the backrest hinge part.

[0009] A further solution: the seat cushion hinge portion is a hinge groove, the backrest hinge portion is a hinge seat, and the hinge seat is rotatably arranged in the hinge groove through a pin shaft.

[0010] A further solution is that a groove is provided on the hinge seat and the opening of the groove faces the side wall of the hinge slot, a pillar parallel to the pin shaft is provided in the groove, and a through hole for the pin shaft to pass through is provided in the middle of the pillar.

[0011] A further solution is that the torsion spring is sleeved on the pillar, and one torsion arm of the torsion spring is fixed on the bottom wall of the groove, and the other torsion arm is located outside the opening of the groove and fixed on the hinged part of the cushion.

[0012] Based on the above technical solution: the above arrangement enables the torsion spring to be located inside the groove, and the structural layout is more reasonable and beautiful.

[0013] A further solution is that a torsion arm mounting groove is provided at the lower side of the cushion hinge part, a cover is detachably provided on the torsion arm mounting groove, and a torsion arm connecting the torsion spring and the cushion hinge part is arranged in the torsion arm mounting groove.

[0014] A further solution is that the seat cushion hinge part, the backrest hinge part, the torsion spring and the pin shaft are each two in number and are arranged in one-to-one correspondence.

[0015] A further solution: the seat cushion hinge portion is a hinge seat, the backrest hinge portion is a hinge slot, and the hinge seat is rotatably arranged in the hinge slot via a pin shaft.

[0016] A further solution: A lumbar support cushion further includes a soft pad, and the soft pad is arranged on the cushion.

[0017] A further solution: A lumbar support cushion also includes a lumbar support backrest pad, and the lumbar support backrest pad is arranged on the lumbar support backrest.

[0018] Based on the above technical solution: by arranging soft cushions and waist-protecting back cushions, people feel more comfortable.

[0019] The beneficial effects of the utility model are:

[0020] The utility model is provided with a seat cushion hinge part and a backrest hinge part that are rotatably connected, and a torsion spring is provided between the seat cushion hinge part and the backrest hinge part. When a person sits on the seat cushion and leans his back on the waist protection backrest, when the person's waist and abdomen adjust the sitting posture forward or backward, the waist protection backrest can use the elastic force of the torsion spring to make adaptive adjustments forward or backward according to the person's sitting posture, so that it can always fit on the waist and abdomen of the human body, provide a certain support to the waist and abdomen, play a role in protecting the waist, and relieve fatigue of the waist and abdomen. It is also convenient to fold for storage, transportation, etc.

[0021] At the same time, when the user twists the waist and abdomen back and forth, the waist support backrest will assist in supporting the waist and abdomen to swing back and forth through the elastic force of the torsion spring, thereby playing a role in assisting in supporting the exercise of the waist and abdomen.
