A pelvic support mechanism for a wheelchair seat has a bracket comprising a generally "L"-shaped, pivoting portion and a stationary portion that is hingedly attached to the "L"-shaped portion. The pelvic support mechanism has a padded pelvic support mounted on said "L"-shaped, pivoting portion, the stationary portion being mounted onto the wheelchair seat. A release lever that is pivotally mounted on said "L"-shaped portion of the bracket. A sliding bolt that is mounted within the "L"-shaped portion of the bracket and which is interconnected with the release lever. A compression spring that is mounted in the "L"-shaped portion of the bracket and that is in contact with the sliding bolt. An opening in the stationary portion of the bracket for receiving the sliding bolt. Wherein the releasable pelvic mechanism has a locked mode in which the sliding bolt is engaged with the opening in the pivoting portion of the bracket, thereby preventing the pelvic support from pivoting, and an unlocked mode in which the sliding bolt is not engaged with the opening in the pivoting portion of the bracket, thereby permitting the pelvic support to pivot.
