Abstract:
The seating system is an inseparable part of any automobile. Its main function is not only to provide a space to the user for driving but also to provide support, comfort and help to ergonomically access the various features and necessary operations of the vehicle. For comfort and accessibility, seats are provided with various mechanisms for adjustments in different directions. Typical mechanisms used for seating adjustment include seatback recliners, lifters (height adjusters), longitudinal adjusters, lumber support, rear seat folding mechanism etc. These mechanisms can be power operated or manual based on vehicle/market requirements. For manual mechanisms, the occupant adjusts the position of seat by operating the mechanism with his/her hand. Often comfort to the occupant during operation is limited to the operating effort of the mechanism. However, as will be shown through this study, operating effort is only one of the parameters which provide overall comfort feeling. Given similar operating effort, there are other parameters that have been identified to contribute to the overall feeling of mechanism’s adjustment. The parameters which affect the operation feeling the occupant experiences are: Initial Stroke, Operational Stiffness, and Over Stroke.
