ABSTRACT:
An apparatus for gripping a human head for use in a neck musculature exercising machine is disclosed. The apparatus includes a pair of side pads adapted to engage the opposing sides of a human head near the ear portions thereof. The side pads are mounted on respective movable cross members, each of which includes a toothed side portion. A control arm is provided for rotating a gear which is engaged on opposite sides thereof with both of the toothed portions of the cross members. Rotation of the control arm causes the cross members and the side pads to be moved simultaneously by equal distances in opposite directions, either both inwardly toward the head or outwardly away from the head. A locking mechanism is provided to maintain the control arm and side pads in a desired position. Chin pads may also be provided in order to more securely grip the enclosed head. Threaded fasteners can be provided to individually adjust any of the side pads or the chin pads to accommodate all shapes and sizes of the enclosed head. The apparatus is connected to a rotatable arm of the neck musculature exercising machine.
