The invention relates to an arresting brake for a wheelchair, having a braking element which is articulated pivotably on a retaining element and, by pivoting a hand brake lever, can be pivoted into an arresting position in which the braking element bears, under pressure, on a wheelchair wheel or its tire. In order to provide a versatile arresting brake for wheelchairs, the invention proposes that the hand brake lever also be mounted on the retaining element, which is pivotably suspended on an adaptor which exhibits fastening device, for fixing it on the wheelchair frame, and a pivot pin which is located in the longitudinal direction of the wheelchair when the adaptor is mounted and about which the retaining element can be pivoted out of a positive locking catch position, which defines the braking function position, into a storage (rest) position located within the outer contour of the wheelchair.

Arresting brake for a wheelchair

A wheelchair brake includes a pressing lever having a free end which pivots bout 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.
