Hello James, 

Please find attached an article about airbag contact modeling https://www.dynasupport.com/tutorial/contact-modeling-in-ls-dyna/airbag-contact

Could you please let us know what type of contact are you using between the airbag and the structure? 

I would recommend starting with CONTACT_AUTOMATIC_SURFACE_TO_SURFACE with SOFT = 1 and it might be required to scale the contact thickness on the airbag side e.g., 1 mm. 

Please let us know how it goes. 
Thank you,
AlexÂ
