dc.description.abstractProlonged sitting, especially during driving or office work, often lead to poor posture and discomfort, increasing the risk of lumber pain and spinal issues. To address this problem, an indigenous lumber support system has been designed and developed with the objective of improving posture and comfort. The mechanism consists of two vertical guided rods that holds the Teflon base, moving and upper plate, while a 12V DC gear motor with a power screw assembly provides controlled vertical motion. Support straps, crossing over the shoulder and waist in rucksack like manner, ensure balanced elevation of ergonomic curve of the hardboard panels, providing both stability and comfort. The design also integrates an automatic limit circuit to prevent overtravel, along with manual adjustment for user preference. As a lightweight, cost-effective and simple to construct solution, the prototype is particularly suitable for use in car seats as a cushion, as well as in other environments requiring prolonged sitting. The system prioritizes user comfort and posture correction without significantly adding to the weight or complexity of the seating structure.
