Abstract
A seat assembly (10) comprising a seat portion (12) and back rest (14) supported on a seat frame (30) with a thigh support (26) movably supported forward of the seat portion (12). The thigh support (26) includes a support portion (42) extending from the seat frame (30) and a bolster (28) supported by the support portion (42). A spring arrangement (44) resiliently interconnects the support portion (42) and the bolster (26) for allowing movement of the entire bolster (26) relative to the support portion (42); for this purpose a pair of leaf springs (46) support the bolster portion (26) in a cantilevered fashion from the support portion (42) and are disposed adjacent each end of the bolster (28). A pair of slideways (52) and corresponding slide members (54) are secured to the frame structure, allowing the bolster (28) to extend between a fully extended to a fully retracted position.
