Abstract
Project of a lumbar area stiffness regulator for an upholstered bed enabling the minimization of the user’s discomfort. The point of this research was creating of a solution for an upholstered bed base that would minimise discomfort during use. The main idea was to create a design of a support layer – a semi-automated chassis with an adjustable lumbar support depending on a user's body shape. Research was conducted that would establish the way the balance and deflection of mass in antropotechnical systems. The analysis was focused on the lumbar and the lower back of the spine during its resting on elastic bands with a manual tension adjustment. In order to establish the tension present where the user's body meets the bed base, an experimental technique was used. A special sensing matt was used. It featured Force Sensitive Applications system. As a result of the analysis, the most optimal spacing of lumbar and lower back tension mechanism was established. The values tested were five, fifty and ninety-five percentile. It was also established that spacing adjustment of the tension mechanism impacts the tension values, and thus, the comfort of use.
