  • Modular dental chair equipment mounting system
    Patent number: 7195219
    Abstract: A system for reconfigurably adapting a dental chair for use, including, e.g., use from the right side or left side, use by right-handed or left-handed practitioners and use in various dentistry practice styles, may include a link arm, a primary arm and a secondary arm. The link arm is pivotably connectible to a rear side of the dental chair. The primary arm is pivotably connectible to the link arm to swing in a generally horizontal plane about a generally vertical axis. The secondary arm is coupleable to the link arm, preferably along substantially the same axis. The secondary arm has multiple pivotably connected segments allowing its distal end to be positioned as desired.
