Rear seat airbag module
First Claim
1. A rear vehicle seat airbag module configured to be mounted to a portion of a seat back of a front vehicle seat comprising:
- an inflator;
an inflatable cushion comprising a lower portion, an upper portion and a first external tether connecting the lower portion and the upper portion, whereinthe inflator provides inflation gas to the inflatable cushion,the inflatable cushion is configured to deploy forward of an occupant seated in a rear vehicle seat such that the occupant loads the upper portion and the lower portion of the inflatable cushion during a frontal collision of a vehicle, andthe first external tether is configured to control a trajectory of deployment of the inflatable cushion by restraining the upper portion from deploying away from the lower portion so that when the cushion is inflated the cushion is configured in a curved shape wherein the upper portion is located above the lower portion, anda second external tether being connected between an inflation point of the lower portion and a point of the lower portion proximate to the inflation point, wherein the second external tether breaks once the lower portion is inflated.

Abstract
A rear vehicle seat airbag module configured to be mounted to a portion of a seat back of a front vehicle seat comprising an inflator and an inflatable cushion comprising a lower portion, an upper portion and an external tether connecting the lower portion and the upper portion. The inflator provides inflation gas to the inflatable cushion and the inflatable cushion is configured to deploy forward of an occupant seated in a rear seat of a vehicle by curving away from the occupant. The external tether is configured to control a trajectory of the deployment of the inflatable cushion by pulling the upper portion toward the lower portion to curve the inflatable cushion such that the upper portion is located above the lower portion.

14. A rear vehicle seat airbag module comprising:
-
an inflator; an inflatable cushion comprising a lower portion, an upper portion and a first external tether connecting the lower portion and the upper portion, wherein the airbag module is configured to be mounted to a portion of a seat back of a front vehicle seat, the inflator provides inflation gas to the inflatable cushion, and the first external tether is configured to control a trajectory of deployment of the inflatable cushion by restraining the upper portion from deploying away from the lower portion to curve the inflatable cushion such that during a frontal collision the inflatable cushion deploys forward of the occupant by curving away from the occupant, and a second external tether being connected between an inflation point of the lower portion and a point of the lower portion proximate to the inflation point, wherein the second external tether breaks once the lower portion is inflated. - View Dependent Claims (15, 16)

17. A rear seat airbag module comprising:
-
an inflatable cushion having a D-shaped geometry and comprising a lower portion and an upper portion, an inflator that provides inflation gas to the inflatable cushion, wherein the inflatable cushion, during a frontal collision, deploys forward of an occupant seated in a rear seat of a vehicle by curving away from the occupant, a first external tether is configured to control a trajectory of deployment of the inflatable cushion by restraining the upper portion from deploying away from the lower portion so that when the cushion is inflated the cushion is configured in a curved shape wherein the upper portion is located above the lower portion, and a second external tether being connected between an inflation point of the lower portion and a point of the lower portion proximate to the inflation point, wherein the second external tether breaks once the lower portion is inflated. - View Dependent Claims (18, 19)
