Abstract: Disclosed embodiments provide a wheelchair bumper wing. The wheelchair bumper wing may be installed on a manual or electric wheelchair. In embodiments, two wheelchair bumper wings are used, with one wheelchair bumper wing installed on each side of the wheelchair. The wheelchair bumper wings serve to protect the wheels and other components of the wheelchair. In particular, when navigating narrow areas such as doorways, it is possible for a wheelchair wheel to collide with an obstruction, such as a pole or wall, which can potentially cause damage to the wheelchair and/or cause injury to the person sitting in the chair. Some wheelchairs can be quite expensive. The wheelchair bumper wings of disclosed embodiments can help to protect wheels, axles, motors, and other components of a wheelchair in the event of side contact with a structure such as a pole, wall, door jam, or other object. Disclosed embodiments can be used with conventional manual wheelchairs and/or motorized wheelchairs.
