Description

Technical Field

[0001] This utility model belongs to the field of seat cushion technology, specifically relating to an adjustable wheelchair seat cushion. Background Technology

[0002] For patients with limited mobility, wheelchairs are their "second legs," a means of transportation in their daily lives that helps them live more independently, travel, participate in social activities, and improve their quality of life. Correct and safe use of wheelchairs can help patients return to daily life and society more quickly, but improper use can not only be uncomfortable and unsafe, but may also cause secondary injuries to the user.

[0003] When rehabilitation patients use wheelchairs, they often find it difficult to sit still or are unaware of their surroundings, causing their buttocks to shift forward after a period of use, resulting in a reclining or leaning posture. However, this posture is detrimental to the patient's rehabilitation and can easily lead to increased tension in the trunk muscles. This invention addresses this issue by proposing an adjustable wheelchair seat cushion. The cushion can detect the user's posture and automatically adjust itself when the patient adopts a reclining or leaning posture, ensuring the user's seat position is consistently maintained between 85 and 90 degrees, thus guaranteeing smooth rehabilitation.
