US Patent 10953835 Support for roof-mounted airbag

A module for a vehicle including a roof and a cabin includes a housing defining a chamber and having an opening in fluid communication with the chamber. The housing is configured for placement in the roof. An airbag is provided in the chamber and is inflatable to a deployed condition extending through the opening into the cabin. A door pivotably connected to the housing closes the opening. The door is pivotable away from the roof in response to deployment of the airbag to provide a reaction surface for the deploying airbag. The door has a first length while closing the opening and a second length greater than the first length when pivoted away from the roof.
