6. A vehicle curtain airbag device comprising:
-
a rear seat chamber configured to inflate and deploy between a head of a rear seat occupant and a vehicle cabin side section, the rear seat chamber including a restraint face that opposes the head in a vehicle width direction and is angled or curved toward a vehicle width direction outer side, on progression toward a vehicle front side, in a fully inflated and deployed state, wherein the rear seat chamber is formed in a shape in which a vehicle width direction inflation width at a location to the vehicle rear side of the center of gravity of the head is thicker than a vehicle width direction inflation width at a location to the vehicle front side of the center of gravity, in the fully inflated and deployed state, and an outer tether that is overlaid on the vehicle width direction inner side of the rear seat chamber and spans between respective front and rear end portions of the rear seat chamber, in the fully inflated and deployed state; wherein in a non-inflated state of the rear seat chamber, the outer tether is set with a front-rear direction dimension shorter than the front-rear direction dimension of the rear seat chamber at the location where the outer tether is overlaid on the rear seat chamber.

7. A vehicle curtain airbag device comprising:
-
a rear seat chamber configured to inflate and deploy between a head of a rear seat occupant and a vehicle cabin side section, the rear seat chamber including a restraint face that opposes the head in a vehicle width direction and is angled or curved toward a vehicle width direction outer side, on progression toward a vehicle front side, in a fully inflated and deployed state, wherein the rear seat chamber is formed in a shape in which a vehicle width direction inflation width at a location to the vehicle rear side of the center of gravity of the head is thicker than a vehicle width direction inflation width at a location to the vehicle front side of the center of gravity, in the fully inflated and deployed state, an outer tether that is overlaid on the vehicle width direction inner side of the rear seat chamber and spans between respective front and rear end portions of the rear seat chamber, in the fully inflated and deployed state, and a cloth similar to the cloth of the curtain airbag is cut out into a substantially triangular shape to form the outer tether; wherein in a non-inflated state of the rear seat chamber, the outer tether is set with a front-rear direction dimension shorter than the front-rear direction dimension of the rear seat chamber at the location where the outer tether is overlaid on the rear seat chamber.
