A wheelchair braking device (10) adapted to automatically engage when the wheelchair (12) to which the device (10) is mounted is unoccupied. The braking device (10) includes a support structure (28) to which is pivotably mounted a sensing lever (14) and a braking lever (22). A biasing element (30) is coupled to the braking lever (22) to bias the braking lever (22) in a first rotational direction relative to the support structure (28) and into engagement with a wheel (32) of the wheelchair (12). The sensing and braking levers (14, 22) are interconnected such that the biasing element (30) operates through the braking lever (22) to bias the sensing lever (14) in a second rotational direction relative to the support structure (28), corresponding to a brake engagement position for the sensing lever (14). As such, the interconnection between the sensing and braking levers (14, 22) causes the braking lever (22) to rotate in a direction opposite to the first rotational direction, thereby disengaging the braking lever (22) from the wheel (32), when the sensing lever (14) is caused to rotate in a direction opposite to the second rotational direction, corresponding to a brake disengagement position for the sensing lever (14). The braking device (10) may further include a hand lever (20) that is interconnected with the sensing lever (14), such that the hand lever (20) is operable to pivot the sensing lever (14) from the engagement position to the disengagement position.
