Description

Technical Field

[0001] The utility model relates to the field of seats, in particular to an elastic lumbar support for chairs. Background Art

[0002] Chairs, as a common piece of furniture, are inseparable from people's work and daily lives. Chairs typically consist of a seat and a backrest, which provide support for the user's hips and back, respectively. Long-term use often leads to lower back pain due to the fixed backrest shape. Furthermore, users require different sitting postures in different environments, and the backrest shape of existing chairs cannot be adjusted to suit user needs.

[0003] Existing chairs often have a gap between the backrest and the user's waist, failing to support the user's waist. This gap is often filled by installing a lumbar support on the backrest. A lumbar support is a pillow for the waist, which can alleviate waist discomfort caused by prolonged sitting to a certain extent. However, existing lumbar supports only support the user's entire waist. When sitting for long periods, the waist needs the most support at the waist's flanks. Existing lumbar supports provide overall support, but provide insufficient support for the flanks. Furthermore, when the user twists their waist in the chair, the lumbar support doesn't always conform to the user's waist. Furthermore, these lumbar supports are bulky, occupy more seat depth, and are expensive to manufacture. Utility Model Content
