Abstract
An occupant protecting device provided inside or below a seat cushion of a vehicle seat, containing: an airbag cushion capable of expanding and deploying to push up a seat surface of the seat cushion; and an inflator that supplies gas for expansion and deployment into the airbag cushion in the event of a vehicle emergency. The airbag cushion has front attaching points and rear attaching points attached to the vehicle seat side, and an expanding and deploying part that is expanded and deployed by the gas from the inflator. At least a portion of the expanding and deploying part overlaps itself in an up-down direction by folding between front attaching points and rear attaching points in a condition prior to expanding and deploying.
Claims19
An occupant protecting device provided inside or below a seat cushion of a vehicle seat, comprising:
- an airbag cushion capable of expanding and deploying to push up a seat surface of the seat cushion, wherein the airbag cushion is formed by stitching together a front base material and a back base material;
- and
- an inflator that supplies gas for expansion and deployment into the airbag cushion in the event of a vehicle emergency, wherein
- the airbag cushion has:
- at least one first attaching point attached to the vehicle seat side;
- at least one second attaching point attached to the vehicle seat side on a rear side of the at least one first attaching point in a front-rear direction of the vehicle seat;
- and
- an expanding and deploying part that is expanded and deployed by the gas from the inflator, and
- at least a portion of the expanding and deploying part overlaps itself in an up-down direction by folding between the at least one first attaching point and the at least one second attaching point in a condition prior to expanding and deploying.

- an airbag cushion capable of expanding and deploying to push up a seat surface of the seat cushion;
- and
- an inflator that supplies gas for expansion and deployment into the airbag cushion in the event of a vehicle emergency, wherein
- the airbag cushion has:
- at least one first attaching point attached to a first securing position of the vehicle seat;
- and
- at least one second attaching point attached to a second securing position of the vehicle seat on a rear side of the at least one first attaching point in a front-rear direction of the vehicle seat, and
- the airbag cushion has a distance between the at least one first attaching point and the at least one second attaching point that is longer than a distance between the first securing position and the second securing position, in a flatly spread out condition prior to attaching to the vehicle seat.
