Abstract: A belt clip for attaching a device to a user includes a back plate having first and second wing portions which include flanges for engaging with the exterior surface of an electronic device. The first and second wing portions are coupled together by an integrated biasing portion that allows the first and second wing portions to be forced together when the flanges are gripping the electronic device and apart when it is desired to remove the electronic device from the belt clip. The wing portions each include integrally formed cam members that engage with a cam hole formed in a clip member. As the clip member is rotated relative to the back plate, the cam members and thus the wing portions are brought together to grasp the electronic device. The clip member is then retained relative to the back plate with a locking feature.

Abstract: A steering mechanism for a wheelchair, consisting of a steering wheel affixed to a shaft, engaging a caster wheel via shaft bearing and adapter to allow the user to better control the direction in which the wheelchair is moving. The steering wheel is positioned parallel to the ground to allow for steering with relative ease. The steering wheel can be placed on either the right or left side of the chair and can be removed to allow the wheelchair to fit through narrow doorways. The assembly extends several inches outwardly from the wheelchair, to avoid interference with leg extensions and to avoid impediments to collapsibility of the chair.
