Occupant protection device
First Claim
1. An occupant protection device mountable on a vehicle for catching a head of an occupant seated in a seat of the vehicle with an inflatable airbag when a collision or a potential collision is detected, the airbag comprising:
- a front panel section inflatable and deployable in front of a backrest of the seat in such a manner as to be opposed to the backrest for catching the head when the head moves forward;
a left panel section inflatable and deployable between a vicinity of a left edge of the backrest and a vicinity of a left edge of the front panel section for catching the head when the head moves towards the left; and
a right panel section inflatable and deployable between a vicinity of a right edge of the backrest and a vicinity of a right edge of the front panel section for catching the head when the head moves towards the right, wherein;
the left panel section and right panel section extend rearward from left and right edges of the front panel section such that the left panel section, front panel section and right panel section form a generally U shape as viewed from above at full deployment of the airbag;
the airbag comprises, in each of the left panel section and right panel section, a frame inflatable region that is inflatable in an inverse-U shape at an upper edge region of each of the left panel section and right panel section, the frame inflatable region including a rear edge inflatable region deployable at a rear edge region of each of the left panel section and right panel section, a front edge inflatable region deployable at a front edge region of each of the left panel section and right panel section and a ceiling edge inflatable region deployable in such a manner as to connect upper ends of the rear edge inflatable region and front edge inflatable region and having gas communication with the rear edge inflatable region and front edge inflatable region; and
the airbag further comprises a regulating member that prevents the frame inflatable regions of the left panel section and right panel section from moving in a separating direction at airbag deployment.

Abstract
An airbag of an occupant protection device as fully deployed includes a front panel section deployable in front of the head of an occupant for catching the head when the head moves forward, a left panel section deployable on a left side of the head for catching the head when the head moves towards the left, and a right panel section deployable on a right side of the head for catching the head when the head moves towards the right. The front panel section includes a main panel region that is deployable in such a manner as to be opposed to a front face of the head and an extended panel region that extends downwardly from the main panel region so as to catch at least an upper part of a thorax of the occupant.
