A pivotable abduction abutment support for a wheelchair or the like is disclosed. The support of the invention has a base member adapted to be fastened under the seat of the wheelchair or the like. The support also has a rod having two opposite ends, one end being mounted about a first pivot located on the base member and having a pivoting axis parallel to a front edge of the seat, and the other end having an abutment fastened to it. The rod can pivot between an upstanding position where the rod extends upwardly and substantially vertically, and a released position where the rod extends downwardly. The support further includes a releasable locking mechanism for releasably locking the rod in the upstanding position, which consists of (i) a retaining portion for engaging the front surface of the rod, the retaining portion lying above the first pivot in order to lock the rod in the upstanding position, (ii) at least one arm extending rearwardly from the retaining portion and having a distal end mounted about a second pivot located on the base member rearwardly of the first pivot, and (iii) a spring for biasing the retaining portion against the rod. By manually pivoting the retaining portion away from the rod, the rod is released and free to pivot downwardly. When the rod is pivoted from the released position to the upstanding position, the spring automatically pivots the retaining portion towards the rod to engage the front surface of the rod and thereby lock the rod in the upstanding position. Alternatively, the retaining portion can be adapted to pivot away from the rod about a pivoting axis parallel to the one of the rod or about a vertical pivoting axis.
