In the straddle-type vehicle including an airbag device in a seat for an occupant, the seat includes a front seat and a rear seat disposed on a rear side and an upper side of the front seat, a step portion is formed between the front seat and the rear seat, the airbag device is disposed on a rear side of the step portion in the seat, and an airbag of the airbag device is to be deployed forward of the vehicle.

First claim

The invention claimed is:

1. A straddle vehicle comprising an airbag device in a seat for an occupant, wherein
the seat includes a front seat and a rear seat disposed on a rear side and an upper side of the front seat,
a step portion is formed between the front seat and the rear seat, and the airbag device is disposed on a rear side of the step portion in the seat,
an airbag of the airbag device is to be deployed forward of the vehicle, and
the airbag includes a forward deployment portion to be deployed forward of the vehicle from the step portion, and an inward deployment portion to be deployed inward in a vehicle width direction from a front part of the forward deployment portion.

2. The straddle vehicle according to claim 1 , wherein
the step portion is positioned on the upper side relative to the front seat, and the airbag is to be deployed forward of the vehicle from at least one of a front surface or a side surface of the step portion.

3. The straddle vehicle according to claim 1 , wherein the airbag is to be deployed to a front side relative to an intermediate portion in a front-and-rear direction of the front seat.

4. The straddle vehicle according to claim 3 , wherein the forward deployment portion includes a first deployment portion to be deployed outward in a vehicle width direction from the step portion, and a second deployment portion to be deployed forward of the vehicle from the first deployment portion, and
the inward deployment portion includes a third deployment portion to be deployed inward in the vehicle width direction from a front end portion of the second deployment portion, and a fourth deployment portion to be deployed in an up-and-down direction from the third deployment portion.

5. The straddle vehicle according to claim 3 , wherein the forward deployment portion is deployed obliquely forward and upward from the step portion, in a vehicle side view.

6. The straddle vehicle according to claim 3 , wherein the forward deployment portion includes a first deployment portion to be deployed outward in the vehicle width direction from the step portion, and a second deployment portion to be deployed forward of the vehicle substantially horizontally from the first deployment portion, and
the inward deployment portion includes a third deployment portion to be deployed inward in the vehicle width direction from the second deployment portion, and a fourth deployment portion to be deployed upward from the third deployment portion.

7. The straddle vehicle according to claim 6 , wherein the forward deployment portion is deployed forward from the step portion to below an arm of an occupant seated on the front seat and gripping a handlebar, and the inward deployment portion extends upward through an inner side in the vehicle width direction of the arm, and covers a trunk of the occupant from a front side.

8. The straddle vehicle according to claim 3 , wherein a pair of left and right forward deployment portions and a pair of left and right inward deployment portions are provided, and
the left and right forward deployment portions, respectively, extend forward on left and right outer sides with respect to a center portion in the vehicle width direction of the front seat.

9. The straddle vehicle according to claim 3 , wherein the forward deployment portion is deployed from below an arm of an occupant seated on the front seat and gripping a handlebar to above the arm through an inner side in the vehicle width direction of the arm, and the inward deployment portion covers a trunk of the occupant from a front side.

10. The straddle vehicle according to claim 3 , wherein the forward deployment portion is deployed forward from the step portion to below an arm of an occupant seated on the front seat and gripping a handlebar, and the inward deployment portion extends upward through an inner side in the vehicle width direction of the arm, and covers a trunk of the occupant from a front side.

11. The straddle vehicle according to claim 1 , wherein the forward deployment portion includes a first deployment portion to be deployed outward in a vehicle width direction from the step portion, and a second deployment portion to be deployed forward of the vehicle from the first deployment portion, and
the inward deployment portion includes a third deployment portion to be deployed inward in the vehicle width direction from a front end portion of the second deployment portion, and a fourth deployment portion to be deployed in an up-and-down direction from the third deployment portion.

12. The straddle vehicle according to claim 1 , wherein the forward deployment portion is deployed obliquely forward and upward from the step portion, in a vehicle side view.

13. The straddle vehicle according to claim 1 , wherein the forward deployment portion includes a first deployment portion to be deployed outward in the vehicle width direction from the step portion, and a second deployment portion to be deployed forward of the vehicle substantially horizontally from the first deployment portion, and
the inward deployment portion includes a third deployment portion to be deployed inward in the vehicle width direction from the second deployment portion, and a fourth deployment portion to be deployed upward from the third deployment portion.

14. The straddle vehicle according to claim 1 , wherein a pair of left and right forward deployment portions and a pair of left and right inward deployment portions are provided, and
the left and right forward deployment portions, respectively, extend forward on left and right outer sides with respect to a center portion in the vehicle width direction of the front seat.

15. The straddle vehicle according to claim 1 , wherein the forward deployment portion is deployed from below an arm of an occupant seated on the front seat and gripping a handlebar to above the arm through an inner side in the vehicle width direction of the arm, and the inward deployment portion covers a trunk of the occupant from a front side.

16. The straddle vehicle according to claim 1 , wherein the forward deployment portion is deployed forward from the step portion to below an arm of an occupant seated on the front seat and gripping a handlebar, and the inward deployment portion extends upward through an inner side in the vehicle width direction of the arm, and covers a trunk of the occupant from a front side.
