A wheelchair brake includes a pressing lever having a free end which pivots about a first axis to make braking contact with a wheelchair wheel. The pressing lever is normally urged into a neutral position away from the wheel by an elastic, spring-like member, such as a rubber band or O-ring. A first brake lever for operating the brake by a companion is connected via a Bowden wire to the free end of the pressing lever, so that depression of the first brake lever causes the pressing lever to pivot into braking contact with the wheel. A manually releasable safety catch automatically engages the first braking lever when the lever is depressed, thereby locking the lever in its braking position. A second brake lever is also provided for use by the wheelchair user. The second lever pivots about a second axis causing a pressure part to bear against the same pressing lever causing a braking contact with the wheel. Further pivoting of the second lever also causes the mechanism to lock in a braking position.

A wheelchair brake comprising: a pressing lever having a free end and an end which is pivoted at a first location; an elastic member which contacts the free end of said pressing lever, thereby urging the free end of said pressing lever into a neutral position; a Bowden wire having first and second ends, said Bowden wire being attached at said first end to the free end of said lever; a first brake lever for operating the brake by a companion, said first brake lever being connected to said second end of said Bowden wire, whereby depression of said first brake lever causes tensioning of said Bowden wire, which in turn causes said pressing lever to pivot from said neutral position into a braking position; a manually releasable catch for locking said first brake lever upon depression; and a second brake lever for operating the brake by a wheelchair user, said second brake lever comprising a handle portion, a portion which is pivoted at a second location, and a pressure portion which bears against said pressing lever when said second brake lever is pivoted, thereby urging said pressing lever into a braking position, said second brake lever and elastic member being arranged such that further pivoting of said second brake lever against the action of said elastic member causes said second brake lever to lock in a manually releasable manner.
