Roof airbag device and occupant protection device
First Claim
1. A roof airbag device comprising:
- a roof airbag housed in a part that includes a front end side in a vehicle longitudinal direction in a center part in a vehicle width direction of a roof,wherein the roof airbag includes;
a front deployed part that is inflated upon reception of a gas supply and is deployed in front in a vehicle longitudinal direction with respect to an occupant such that a lower end side in a vehicle up-and-down direction overlaps with an instrument panel in an up-and-down direction in a rear view;
a rear deployed part that is inflated upon reception of the gas supply and is at least partially deployed between right and left seats; and
a thin deployed part that is deployed in a state connected with an inflated and deployed part that includes the front deployed part and the rear deployed part and surrounded by the inflated and deployed part, and in non-inflation or in inflation at a thickness thinner than an inflation width of the inflated and deployed part in a vehicle width direction,wherein the thin deployed part extends between a rear surface of the front deployed part, in the vehicle longitudinal direction, and a front surface of the rear deployed part, in the vehicle longitudinal direction,wherein the front deployed part is formed by including a pair of cylindrically deployed parts that are inflated and deployed on both sides of right and left with respect to the thin deployed part.

Abstract
A roof airbag device includes a roof airbag housed in a part that includes a front end side in a vehicle longitudinal direction in a center part in a vehicle width direction of a roof. The roof airbag includes: a front deployed part that is deployed in front in a vehicle longitudinal direction with respect to an occupant such that a lower end side in a vehicle up-and-down direction overlaps with an instrument panel in an up-and-down direction in a rear view; a rear deployed part that is at least partially deployed between right and left seats; and a thin deployed part that is deployed in a state connected with the front deployed part and the rear deployed part and surrounded by these deployed part, and in non-inflation or in inflation at a thickness thinner than an inflation width of the inflated and deployed part in a vehicle width direction.
