Abstract

A collision protection system for a vehicle, the collision protection system including a seat having a seat back and at least one lateral support coupled to the seat back, where the at least one lateral support deploys based on one or more collision policies. The collision protection system further includes a side airbag, where the side airbag deploys based on the one or more collision policies, and where the at least one lateral support deploys between the seat and the side airbag to protect a user occupying the seat during a collision.

First claim

What is claimed is:

1 . A collision protection system for a vehicle, the collision protection system comprising:
a seat having a seat back; at least one lateral support coupled to the seat back, wherein the at least one lateral support is a bolster integrated into the seat back that supports a user occupying the seat in a non-deployed configuration, and wherein the at least one lateral support deploys based on one or more collision policies; and a side airbag, wherein the side airbag deploys from a side of the vehicle towards the seat based on the one or more collision policies, and wherein the at least one lateral support deploys by elongating forwards towards a front of the vehicle between the seat and the side airbag such that the deployed side airbag contacts the deployed at least one lateral support and not the user occupying the seat to protect the user occupying the seat during a collision.

2 . The collision protection system of claim 1 , wherein the at least one lateral support deploys using a pyrotechnic or compressed gas inflater.

3 . The collision protection system of claim 1 , wherein the at least one lateral support further deploys by inflating against a side of the user.

4 . The collision protection system of claim 1 , wherein the at least one lateral support comprises two lateral supports, and wherein the two lateral supports deploy to enhance protection of the user.

5 . The collision protection system of claim 1 , wherein at least one collision policy of the one or more collision policies causes the at least one lateral support to deploy in response to a pre-crash warning signal.

6 . The collision protection system of claim 1 , wherein at least one collision policy of the one or more collision policies causes the at least one lateral support to deploy in response to a crash detection signal.

7 . The collision protection system of claim 1 , wherein at least one collision policy of the one or more collision policies causes the at least one lateral support to deploy at a slower rate than a deployment rate of the side airbag.

8 . A side-impact protection assembly for a vehicle, the side-impact protection assembly comprising:
at least one lateral support coupled to a seat back of a seat, wherein the at least one lateral support is a bolster integrated into the seat back that supports a user occupying the seat in a non-deployed configuration, and wherein the at least one lateral support deploys based on one or more collision policies; and a side airbag, wherein the side airbag deploys from a side of the vehicle towards the seat based on the one or more collision policies, and wherein the at least one lateral support deploys by elongating forwards towards a front of the vehicle between the seat and the side airbag such that the deployed side airbag contacts the deployed at least one lateral support and not the user occupying the seat to protect the user occupying the seat during a collision.

9 . The side-impact protection assembly of claim 8 , wherein the at least one lateral support deploys using a pyrotechnic or compressed gas inflater.

10 . The side-impact protection assembly of claim 8 , wherein the at least one lateral support further deploys by inflating against a side of the user.

11 . The side-impact protection assembly of claim 8 , wherein the at least one lateral support comprises two lateral supports, and wherein the two lateral supports deploy to enhance protection of the user.

12 . The side-impact protection assembly of claim 8 , wherein at least one collision policy of the one or more collision policies causes the at least one lateral support to deploy in response to a pre-crash warning signal.

13 . The side-impact protection assembly of claim 8 , wherein at least one collision policy of the one or more collision policies causes the at least one lateral support to deploy in response to a crash detection signal.

14 . The side-impact protection assembly of claim 8 , wherein at least one collision policy of the one or more collision policies causes the at least one lateral support to deploy at a slower rate than a deployment rate of the side airbag.

15 . A method comprising:
detecting a collision indication signal; deploying at least one lateral support coupled to a seat back of a seat of a vehicle, wherein the at least one lateral support is a bolster integrated into the seat back that supports a user occupying the seat in a non-deployed configuration, and wherein the at least one lateral support deploys based on one or more collision policies; and deploying a side airbag, wherein the side airbag deploys from a side of the vehicle towards the seat based on the one or more collision policies, and wherein the at least one lateral support deploys by elongating forwards towards a front of the vehicle between the seat and the side airbag such that the deployed side airbag contacts the deployed at least one lateral support and not the user occupying the seat to protect the user occupying the seat during a collision.

16 . The method of claim 15 , wherein the at least one lateral support deploys using a pyrotechnic or compressed gas inflater.

17 . The method of claim 15 , wherein the at least one lateral support further deploys by inflating against a side of the user.

18 . The method of claim 15 , wherein the at least one lateral support comprises two lateral supports, and wherein the two lateral supports deploy to enhance protection of the user.

19 . The method of claim 15 , wherein at least one collision policy of the one or more collision policies causes the at least one lateral support to deploy in response to a pre-crash warning signal.

20 . The method of claim 15 , wherein at least one collision policy of the one or more collision policies causes the at least one lateral support to deploy in response to a crash detection signal.
