ABSTRACT:
A device for precisely positioning and locking an object in a selective position including a first arm, a second arm, a third arm and a fourth arm, as well as an L-shaped arm connecting the third and fourth arms. The arms are structured so as to movably connect a support for an object, such as a head rest, to a base member, such as an operating table. The arms are structured so as to slidably engage with one another in order to allow positioning of the support for the object in any desired position in a three dimensional space. The first arm is slidably mounted to a connection to the base member.
