Abstract
An automatically engageable and releasable brake apparatus for a wheelchair, including a connection mechanism adapted to be attached to a portion of the frame of the wheelchair proximate a rear wheel of the wheelchair, a seat actuation member extending from a portion of the connection mechanism and adapted to be positioned substantially beneath the seat of the wheelchair, a shaft member positioned to extend substantially downwardly from a portion of the connection mechanism and a friction member positioned proximate the other end of the shaft member and adapted to contact the ground. Occupational ingress activates the seat actuation member to move from a first position to a second position, which causes the shaft member to rotate in concert therewith such that the friction member also moves from a first position in substantial contact with the ground to a second position spaced a distance above the ground.
