Advanced elastomeric integral suspension seating system

摘要

A vehicle seat formed by a contoured tubular frame defining the edges of a seat base and a seat back and having tensioned belts and an elastomeric mesh seat fabric. The contoured tubular frame is wrapped in foam padding for comfort and impact protection. Two belts are provided in each of the seat base and seat back. The elastomeric seat mesh fabric forms an elastomeric seating surface that wraps around the seat occupant. The elastomeric mesh seat fabric is secured to the belts that provide seating surface contour and minimize excursion of the elastomeric mesh seat fabric. A cushion is provided under the elastomeric seating surface near the front of the seat to prevent submarining in an impact. An eccentric lumbar cushion is provided on a flexible shaft to permit adjustment of the degree of lower back support.
