Abstract:
1. A pelvic support apparatus for a seat having a seat back and a seat pan, the pelvic support apparatus comprising: a frame positioned within the seat back; a pelvic support member coupled with the frame adjacent a bottom of the seat back and a rear of the seat pan, the pelvic support member movable between a first, retracted position, and a second, extended position that provides support to a pelvic area of a person seated in the seat from behind the pelvic area, the pelvic support member having first and second lateral support portions operable to provide support to the pelvic area, each lateral support portion spaced from a central axis of the seat back; and a guide member coupled with the frame and the pelvic support member to guide movement of the pelvic support member relative to the frame, the guide member including an arcuate surface engaging an arcuate portion of the pelvic support member such that the pelvic support member is movable along an arcuate path between the first and second positions; wherein the pelvic support member does not include any portion aligned with the central axis and that provides support to the pelvic area, thereby preventing direct pressure from being applied to the person's sacrum or coccyx.
