Abstract

An occupant protection device for a vehicle includes: a three-point seatbelt device having a seatbelt extendable across a front of an upper body of an occupant sitting on a seat; and a belt airbag device including a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt the belt airbag being configured to be deployed when a collision occurs. The belt airbag includes a belt-direction deployment section extendable and deployable along the shoulder belt section, and an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section. The belt-direction deployment section and the intersecting-direction deployment section are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat.

First claim

The invention claimed is:

1. An occupant protection device for a vehicle, the occupant protection device comprising:
a seat on which an occupant to board the vehicle is to sit;
a three-point seatbelt device including a seatbelt extendable across a front of an upper body of the occupant sitting on the seat; and
a belt airbag device comprising a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt, the belt airbag being configured to be deployed when a collision occurs,
wherein the belt airbag comprises:
a belt-direction deployment section extendable and deployable along the shoulder belt section; and
an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section,

wherein the belt-direction deployment section and the intersecting-direction deployment section are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat,
wherein the belt-direction deployment section is longer than the intersecting-direction deployment section when the belt-direction deployment section extends along the shoulder belt section, and
wherein a filler that fills a space between the belt-direction deployment section and the intersecting-direction deployment section is formed above an area where the belt-direction deployment section and the intersecting-direction deployment section are coupled to each other.

2. An occupant protection device for a vehicle, the occupant protection device comprising:
a seat on which an occupant to board the vehicle is to sit;
a three-point seatbelt device including a seatbelt extendable across a front of an upper body of the occupant sitting on the seat; and
a belt airbag device comprising a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt, the belt airbag being configured to be deployed when a collision occurs,
wherein the belt airbag comprises:
a belt-direction deployment section extendable and deployable along the shoulder belt section; and
an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section,

wherein the belt-direction deployment section and the intersecting-direction deployment section are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat,
wherein the belt-direction deployment section is longer than the intersecting-direction deployment section when the belt-direction deployment section extends along the shoulder belt section,
wherein the belt-direction deployment section and the intersecting-direction deployment section form a substantially X-shape by being coupled to each other at centers thereof, and
wherein a filler that fills a space between the belt-direction deployment section and the intersecting-direction deployment section is formed above an area where the belt-direction deployment section and the intersecting-direction deployment section are coupled to each other.

3. An occupant protection device for a vehicle, the occupant protection device comprising:
a seat on which an occupant to board the vehicle is to sit;
a three-point seatbelt device including a seatbelt extendable across a front of an upper body of the occupant sitting on the seat; and
a belt airbag device comprising a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt, the belt airbag being configured to be deployed when a collision occurs,
wherein the belt airbag comprises:
a belt-direction deployment section extendable and deployable along the shoulder belt section; and
an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section,

wherein the belt-direction deployment section and the intersecting-direction deployment section are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat,
wherein the belt-direction deployment section is longer than the intersecting-direction deployment section when the belt-direction deployment section extends along the shoulder belt section, and
wherein the belt-direction deployment section and the intersecting-direction deployment section form a substantially X-shape by being coupled to each other at centers thereof.

4. The occupant protection device for a vehicle according to claim 3 , wherein a filler that fills a space between the belt-direction deployment section and the intersecting-direction deployment section is formed above an area where the belt-direction deployment section and the intersecting-direction deployment section are coupled to each other.
