Adjusting the double articulating headrest

The double articulating headrest is equipped with two rotary joints. They
facilitate manual adjustment of head inclination for maxillary/mandibular
treatments. The headrest extension can be pushed in or pulled out
manually to adjust it to the height of the patient.
CAUTION
When the lock on the double articulating headrest is released, the
both rotary joints lose their holding power.
If the headrest is not supported when the lock is released, the
patient's head might suddenly fall backward.
➢ Always support the headrest and thus the patient's head prior to
releasing the locking mechanism on the double articulating
headrest!
➢ Place your hands so your fingers will not be pinched.
➢ Tell the patient that you are going to adjust the headrest.
➢ Before releasing the headrest, always ensure that both joints are
securely locked.
1. Place one hand under the headrest to support the patient's head.
2. Use the other hand to press the release button A.
Ä Both rotary joints are now freely movable.
3. Adjust the headrest to the desired treatment position. Then let go of
the release button A.
Ä Both rotary joints lock into place. Ensure that the joints are
securely positioned! The headrest is secure again.
