A seat with pelvic support having a seat bottom (10), a panel (22) of elastomeric material retained under an initial tension spanning a framework (28) of the seat bottom (10), and a resiliently deflectable pelvic support structure (32, 62) retained in spaced relation from the panel (22) of elastomeric material. The resiliently deflectable pelvic support structure (32, 62) provides supplemental support to the seat occupant when the panel (22) of elastomeric material is sufficiently deflected. The resiliently deflectable pelvic support structure (32) can be formed by a plurality of resiliently deflectable fingers (32). The fingers (32), which can have different deflection resistances to establish hyper-localized resistance control, can project outboard from a central member (30) or inboard from the framework (28). A U-shaped rigidifying member (26) can be secured to the framework (28), and a seat back (44) can retain a support and positioning member (82) in a fixed angular orientation relative to the seat bottom (10). |
