Description

Adjustable waist cushion

[ field of technology ]

The utility model relates to a seat cushion, in particular to an adjustable waist cushion.

[ background Art ]

Poor sitting posture is not a matter of light weight. Over time, this can lead to overstressing and stress of our stabilizing musculature and lower back spinal joints. In addition to hidden pain, minimal daily tasks become difficult to perform. Sedentary sitting can quickly lead to lumbago. The slight curvature you feel when you move along the lower back requires proper lumbar support. Everyone can involuntarily tilt too far backward or forward without deliberate effort, resulting in a poor posture.

When you sit in bad posture for several hours, additional pressure is applied to your spine and its stabilizing structures (e.g., ligaments). Ligaments can resist pulling forces, but if you are in a flexed position for a long time they begin to lengthen, which is called "creep" in technical terms. Creep can stress and muscular fatigue of your lower back tissue, resulting in back pain.

To address this problem, lumbar bolsters have been used to support the lumbar region (lower back) and reduce ligament creep. The lumbar pad also helps to better align your spine, which would be very difficult to maintain without good lumbar support. It is particularly important to have a good lumbar cushion if you work for several hours in a sitting position.

The waist cushion quickly becomes a comfortable and happy investment for people. The design of the lumbar support pad ensures that it fits in any seat and provides you with the required lumbar support when sitting for a long period of time. There are a variety of lumbar pads on the market. However, these lumbar pads are fixed and are not adjustable in nature.

A fixed lumbar support is a lumbar support that is fixed to the seat back and cannot be repositioned or adjusted in any way. The fixed lumbar pad is built on a foam pad, while basic and versatile for each user, it provides a more ergonomic benefit relative to the absence of any specialized lumbar pad. However, because of the unique differences in curvature of the spine of each individual, if the fixed lumbar support is positioned incorrectly, it is too high, too low, too little or too much, which can be counterproductive. Thus, if the lumbar support is fixed and non-adjustable, the user is currently unable to adjust the degree of lumbar support, which is essentially only one spinal column of the lumbar region.

The information disclosed in this background section is only for enhancement of understanding of the general background defined in this disclosure and is not to be taken as an admission or any form of suggestion that this information forms the prior art that is known to a person skilled in the art.

[ utility model ]

[ detailed description ] of the utility model

The utility model is described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 to 7, an adjustable lumbar support 100 comprises a seating surface 120 having a first concave surface for receiving buttocks and thighs of a user, a backrest 110 having a second concave surface for receiving the back of the user, the seating surface 120 and the backrest 110 forming a one-piece portable foam pad, at least one adjustment strap 130 connected to the seating surface 120 and the backrest 110, the seating surface 120 being disposed at an angle of 0-180 ° with respect to the backrest 110, the adjustment strap 130 being secured to the back of the backrest 110 and the bottom surface of the seating surface 120, the curvature 140 of the lumbar or spine of the backrest 110 being operatively increased or decreased by the adjustment strap 130. In this embodiment, the height of the back rest 110 may be 15 inches, the length of the seating surface 120 may be 14.5 inches, and the width of the back rest 110 and seating surface 120 may be 18 inches. In addition, the seating surface 120 and the back rest 110 form a lumbar or spine curvature 140 near the lower half of the back rest 110. The curvature 140 of the waist or spine helps to improve the user's sitting posture while also improving the alignment of the thoracic and cervical vertebrae.

In some embodiments, the adjustment strap 130 has at least one of a letter day button 131 and a buckle 132 on either side of the backrest 110. In this embodiment, the number of the day buckles 131 and the number of the eye-splice 132 are 1 on both sides of the backrest 110.

In some embodiments, tightening or releasing the adjustment strap 130 via the Japanese character buckle 131 and the stab buckle 132 serves to increase or decrease the lumbar or spine curvature 140 of the backrest 110. The eye-splice 132 may be used to connect the adjustment strap 130 of the backrest 110 and the adjustment strap 130 of the seating surface 120, while the letter-splice 131 at both ends of the backrest 110 is used to pull the backrest 110 toward the seating surface 120 or to release the backrest 110 from the seating surface 120. Pulling or releasing the adjustment strap 130 via the cam 131 results in an increase or decrease in the curvature 140 of the waist or spine. The strength of the waist cushion is adjusted by adjusting the bending rate of the spine, so that the sitting posture of a user can be improved, and meanwhile, the arrangement of the thoracic vertebrae and the cervical vertebrae can be improved. In addition, the user can adjust the degree of lumbar support as desired, which is not the case with existing lumbar pads. Thus, the adjustable lumbar support cushion acts to adjust the lumbar support.

In certain embodiments, the first concave surface includes a first convex surface 121 and a second convex surface 123 for supporting the buttocks and thighs of the user. The first convex surface and the second convex surface can maximize blood flow in the buttocks and thighs. The first convex surface 121 and the second convex surface 123 may be separated by a hollow region 150. The hollow region 150 facilitates ventilation of air through the seating surface 120, thereby providing comfort to a user sitting on the lumbar pad for a prolonged period of time.

The first concave surface may evenly distribute the weight of the user over the seating surface 120. The first concave surface facilitates pressure relief or distribution to prevent local overpressure. In addition, it helps maintain the neutral position of the spine, which may help reduce excessive wear and tear of the spine and intervertebral discs by reducing mechanical stress on the spine, thereby reducing the user's legs, lower back and mid-back, neck and shoulders.

In certain embodiments, the second concave surface comprises a third convex surface 101 and a fourth convex surface 103 for supporting the back of the user.

In certain embodiments, the portable foam pad is comprised of a breathable foam pad. The breathable foam may reduce local pressure and help improve air circulation.

In certain embodiments, the breathable foam pad is comprised of a bamboo charcoal high density foam and a mesh, which is covered by an inner sleeve to protect the breathable foam pad.

In some embodiments, the backrest 110 includes a plurality of bumps to facilitate activation of the stabilized musculature of the user's spine. The bumps are formed on the surface of the portable foam pad at the time of manufacture to promote activation of the stable musculature of the spinal column.

In some embodiments, the adjustment strap 130 is secured to the fabric 125, and the fabric 125 covers the portable foam pad as an outer sleeve. The adjustment strap 130 may be secured to the fabric 125 using any means known to those skilled in the art, such as stitching. The back of the fabric 125 provides a first contact point 102 and a second contact point 104 for securing the adjustment strap 130, the first contact point 102 and the second contact point 104 being specifically spaced apart to cradle the back rest 110. The bottom surface of the fabric 125 is provided with a third contact point 122 and a fourth contact point 124 for securing the adjustment strap 130, the third contact point 122 and the fourth contact point 124 being specifically spaced apart to cradle the seating surface 120. The eye-splice 132 is disposed on both sides of the seating surface 120 and adjacent to the third contact point 122 and the fourth contact point 124.

The present utility model has been described above in connection with the preferred embodiments, but the present utility model is not limited to the embodiments disclosed above, but it is intended to cover various modifications, equivalent combinations according to the essence of the present embodiments.
