Influence of Lumbar Support Prominence for a Car Seat in the Seating Pressure and Discomfort Perception

The sustained and prolonged posture in driving is associated with leg and lower back musculoskeletal problems. The seat should allow the reduction of the pressure that the body exerts on the seat, the maintenance of the lordotic curve and the reduction of discomfort. Therefore, it was intended to study how a change in the prominence of the driver’s car seat lumbar support, affects discomfort perception, pressure, and force between the body and the seat pan.
