Abstract: A leg support accessory for a wheelchair including a leg rest wider than the wheelchair seat, a vertical support secured at an upper end to the leg rest and including in its lower end a downwardly open recess adapted to receive the foot rest supports, and first and second braces each fixed on one end to the vertical support and at the other end having an opening adapted to fixedly receive one of the arm support posts. When the accessory is used with the wheelchair, the braces receive arm support posts on opposite sides of the seat, and the foot rest supports in their raised position are received in the vertical support recess with the leg rest supported in a substantially horizontal orientation with lateral ends extending beyond the sides of the seat.
