Airbag assembly

摘要

An airbag includes a rear panel, a front panel, and an extension panel. The rear panel has an inflation aperture for receiving an inflation gas. The front panel has at least one communication aperture, and the front panel is connected to the rear panel at a peripheral seam to define a primary inflatable portion having a central axis. The extension panel has an inner edge that is connected to the front panel at a location that is offset from the central axis of the primary inflatable portion and an outer edge that is connected to at least one of the front panel or the rear panel to define a secondary inflatable portion that is in communication with the primary inflatable portion through the at least one communication aperture. When inflated by the inflation gas, the secondary inflatable portion extends outward with respect to the front panel toward a vehicle occupant.

1. An airbag comprising:
a rear panel having an inflation aperture for receiving an inflation gas; a front panel having at least one communication aperture, and the front panel is connected to the rear panel at a peripheral seam to define a primary inflatable portion having a central axis; and an extension panel having an inner edge that is connected to the front panel at a location that is offset from the central axis of the primary inflatable portion and an outer edge that is connected to at least one of the front panel or the rear panel to define a secondary inflatable portion that is in communication with the primary inflatable portion through the at least one communication aperture and, when the primary inflatable portion is inflated by the inflation gas, a portion of the inflation gas passes through the at least one communication aperture to inflate the extension panel such that the extension panel extends outward with respect to the front panel toward a vehicle occupant, the front panel defines an occupant-facing surface around the central axis of the primary inflatable portion, the occupant-facing surface of the front panel is exposed to the vehicle occupant, and at least part of the extension panel is disposed farther from the inflation aperture of the rear panel in a direction parallel to the central axis than a furthest portion of the occupant-facing surface of the front panel at full inflation.
