Zusammenfassung:	A patient interface is configured to deliver breathable gas to a patient. The patient interface includes a cushion configured to form a seal with the patient's face and a frame with an elongated body comprising a central bore and a circumferential channel. The circumferential channel is configured to receive a rim of the cushion. Headgear is attachable to the frame and is configured to support the cushion and the frame on the patient's head. The headgear includes a left rigidizer attached to a left front strap and a right rigidizer attached to a right front strap. The left and right rigidizers are arranged to have different flexibilities in different directions so that a stiffness of the left and right rigidizers in a first direction resist a vertical rotation of the patient interface.
