Abstract
A seat spring unit for use in the seats of vehicles, chairs, sofas and the like. The unit utilizes flat spring steel members arranged in a generally parallel arrangement from the front to rear frame members of the seat. Each of the spring steel members is formed with one of more downwardly extending vee-arches near the front and/or rear frame member to provide flexibility, comfort and support for the seat cushions while greatly simplifying the structure of the unit. Additionally, the center portion of each spring member has an upwardly crowned area between the vee-arches to better control the load deflection.
