The protective device is made of a flexible elastomeric material and is separable on one side with a cavity for the leg rest bracket plate and a central hole to encompass the leg post and the bracket pin. When deployed the bumper provides protective buffer surrounding the exposed bracket reducing the risk of injuries such as scrapes and skin tears caused by exposed wheelchair leg rest brackets.

  • Patent number: 7234717
    Abstract: For a manually propelled wheelchair having a rear wheel located on either side of the wheelchair, each rear wheel including an annular or round push rim of substantially uniform, uninterrupted cross section, a grip attachment attachable to the rim used by an occupant of the wheelchair to propel the wheelchair. The grip attachment includes a gripping body having a preferably convex palm-pushing surface on a posterior side thereof and a preferably concave finger-pulling surface on an anterior side thereof. A rim-engaging member having an annular or circular-shaped attached to each rear wheel is adapted to cooperate with the gripping body to clampingly secure the gripping body to the rim in a laterally outwardly extending orientation. By this arrangement, an occupant may propel the wheelchair forwardly by exerting palm pressure against the posterior side and rearwardly by exerting finger pressure against the anterior side.
