Abstract

The invention provides a head protection gasbag device. In the invention, a gasbag comprises an expansion main body which is expanded by gas for expansion flowing inside the gasbag from an aerator, and a joint which is protruded from the upper edge of the expansion main body and is connected with the aerator. The expansion main body is provided with an assistant armrest neighbouring part which is extended from the join and is arranged below an assistant armrest when the gasbag is folded for standby. The assistant armrest nerghbouring part is provided with an offset part in a periphery part which is arranged at the upper edge side when expansion is completed and prevents gas from flowing inwards. The offset part is offset downwards comparing with the periphery part which is arranged at the upper edge side of other parts in the expansion main body.

Description

technical field [0001] The present invention relates to a head protection airbag device mounted on a vehicle having an auxiliary armrest disposed on the upper edge side of a window, and having an airbag folded and accommodated in a region below the auxiliary armrest on the upper edge side of the window. Background technique [0002] At present, as a head protection airbag device mounted on a vehicle equipped with an auxiliary armrest, there is a head protection airbag device disclosed in JP-A-2005-14633. In a conventional head protection airbag device, the airbag has an inflatable main body, which is inflated by flowing inflation gas inside to cover the vehicle inner side of the window, and the following connection port is arranged at a position near the auxiliary armrest. On the upper side, the connection port protrudes upward from the upper edge side of the inflatable main body when the inflation is completed, and is connected to the inflator that supplies inflation gas in...
