Abstract

Automotive seat design has been always challenge for engineers as design parameters for automotive seats are complex. Three design objectives, to be satisfied simultaneously are comfort, safety, and health. For comfort, various ergonomic and human factors considerations are discussed ranging from seat dimensions and adjustments to cushioning and occupant perceptions of comfort. For safety, the principal consideration is the effectiveness of the seat in providing spinal support during accidents-particularly in rear end collisions. An additional safety consideration is the ability of the seat to keep an occupant “in position” during an accident. Finally, for health concerns, the focus is upon maintenance of spinal stability, seat ergonomics, and road induced vibration attenuation. The paper presents design parameters satisfying these design objectives. These parameters include seat dimensions and their adjustments; cushioning for vibration suppression; fabric design to help maintain occupant position during periods of high acceleration; back rest strength for thoracic and lumbar spine protection; and head rest geometry for cervical spine protection.
