Patent attributes
An airbag includes a main inflatable section which includes a front-collision arresting face at the rear plane as deployed, a protruding inflatable section which includes an oblique-collision arresting face, and an arresting recess formed between the front-collision arresting face and oblique-collision arresting face. The airbag internally includes a recess-pulling tether which joints the leading end of the arresting recess and a front end portion of the airbag as deployed, and a regulating tether which extends from the leading end of the arresting recess towards a far-side wall of the protruding inflatable section which is opposed to the oblique-collision arresting face. A joint position of the regulating tether to the far-side wall is such a position that would produce a pulling force which pulls the protruding inflatable section towards the rear plane of the main inflatable section when the leading end of the arresting recess moves forward at catching a passenger.
