Head positioning device for a dental X-ray diagnosis unit

摘要

The invention relates to a head positioning device for a dental X-ray diagnosis unit, in particular for pantomograms. The device comprises a chin support (9) whose height can be adjusted to suit the patient and a forehead support (8) which can also be adjusted in the horizontal direction and can be aligned on the patient's head. In order to achieve a simpler support of the patient's head it is proposed that the forehead support (8) be of bracket-shaped design, the bracket having struts (8b) which extend on both sides of the patient's head and whose bent ends (8c) which face each other are guided in a guide member (13) in opposite directions such that the struts (8b) can be adjusted to suit the width (B) of the patient's face. The front section (8a) of the forehead support (8) against which the forehead of the patient's head can rest is designed such that it can be adjusted to suit the adjusted width of the struts (8b). For this purpose, the forehead support (8) may be transversely divided in its front section (8a) or may be made of a flexible material. <IMAGE>
