2022 XC 90

[Dalysmandel]

I am renting a 2022 XC 90. My daughter put the front passenger seatbelt behind the seat headrest. The seatbelt has tightened up and locked. Thus I am unable to get the seatbelt around or off the headrest. I've goggled and searched and on some models (maybe older?) There is suppose to be buttons to depress through the back of the chair leather or plastic releasing the head rest. But I cannot get this to work. I am hoping someone can help me fix this myself instead of booking an appt at the dealer while on vacation.

Thanks
