Abstract

The disclosure provides for a system. The system may include a rotational control system configured to rotate a seat of a vehicle, and one or more computing devices. The one or more computing devices may have one or more processors that are configured to determine that an impact is imminent at a location on the vehicle along a collision axis. A most favorable orientation may be determined by the one or more processors based on the determined location and collision axis. Using the rotational control system, the one or more processors may rotate the seat of the vehicle to the most favorable orientation in order to reduce risks of serious injury to a passenger in the seat caused by the imminent impact. A translational control system may be used by the one or more processors to translate the seat of the vehicle to a position relative to the determined location.

First claim

The invention claimed is:

1. A method comprising:
determining, by one or more computing devices, that an impact is imminent at a location on a vehicle along a collision axis;
positioning, by the one or more computing devices, a seat of the vehicle relative to the location and the collision axis in order to reduce risks of serious injury to a passenger in the seat upon the impact; and
translating, by the one or more computing devices, the seat of the vehicle to reduce risks of serious injury to the passenger by sliding a base portion of the seat along a guide rail while using a fluid or a deformable material to absorb at least a portion of energy caused by the impact.

2. The method of claim 1 , further comprising translating, by the one or more computing devices, the seat of the vehicle a distance away from the location prior to the impact to reduce risks of serious injury to the passenger in the seat upon the impact.

3. The method of claim 1 , wherein the positioning includes rotating, by the one or more computing devices, the seat of the vehicle to a most favorable orientation prior to the impact, the most favorable orientation being an angle to the collision axis at which there is at least one of (i) a least likelihood of injury to the passenger in the seat or (ii) a highest performance of a personal restraint system.

4. The method of claim 3 , further comprising determining, by the one or more computing devices, the most favorable orientation of the seat in the vehicle based on the location and the collision axis.

5. The method of claim 3 , wherein the most favorable orientation of the seat is an angle that is parallel to the collision axis with a front of the seat facing away from the location.

6. The method of claim 1 , wherein the translating of the seat of the vehicle allows the passenger in the seat to translate along the collision axis independent from the seat of the vehicle.

7. The method of claim 6 , wherein the seat comprises the deformable material such that the passenger in the seat may translate during the impact independent from the seat.

8. A system comprising:
a translational control system including a guide rail along which a seat of a vehicle is configured to move; and
one or more computing devices having one or more processors configured to:
determine that an impact is imminent at a location on the vehicle along a collision axis;
position the seat of the vehicle relative to the location and the collision axis in order to reduce risks of serious injury to a passenger in the seat upon the impact; and
use a fluid or a deformable material to absorb at least a portion of energy caused by the impact while sliding a base portion of the seat along the guide rail.

9. The system of claim 8 , wherein the one or more computing devices is further configured to translate, using the translational control system, the seat of the vehicle a distance away from the location prior to the impact to reduce risks of serious injury to the passenger in the seat upon the impact.

10. The system of claim 8 , further comprising a rotational control system configured to translate the seat of the vehicle, wherein the one or more computing devices is configured to position, using the rotational control system, the seat of the vehicle to a most favorable orientation prior to the impact, the most favorable orientation being an angle to the collision axis at which there is at least one of (i) a least likelihood of injury to the passenger in the seat or (ii) a highest performance of a personal restraint system.

11. The system of claim 10 , wherein the one or more computing devices is further configured to determine the most favorable orientation of the seat in the vehicle based on the location and the collision axis.

12. The system of claim 10 , wherein the most favorable orientation of the seat is an angle that is parallel to the collision axis with a front of the seat facing away from the location.

13. The system of claim 8 , wherein the seat of the vehicle is configured to allow the passenger in the seat to translate along the collision axis independent from the seat of the vehicle.

14. The system of claim 13 , wherein the seat comprises the deformable material such that the passenger in the seat may translate during the impact independent from the seat.

15. The system of claim 8 , wherein the system is comprised by the vehicle.

16. The system of claim 15 , wherein the vehicle is capable of operating autonomously.

17. A non-transitory, computer-readable medium on which instructions are stored, the instructions, when executed by one or more computing devices, causing the one or more computing devices to perform a method, the method comprising:
determining that an impact is imminent at a location on a vehicle along a collision axis;
positioning a seat of the vehicle relative to the location and the collision axis in order to reduce risks of serious injury to a passenger in the seat upon the impact; and
using a fluid or a deformable material to absorb at least a portion of energy caused by the impact while sliding a base portion of the seat along a guide rail.

18. The medium of claim 17 , wherein the method further comprises translating the seat of the vehicle a distance away from the location prior to the impact to reduce risks of serious injury to the passenger in the seat upon the impact.

19. The medium of claim 17 , wherein the positioning includes rotating the seat of the vehicle to a most favorable orientation prior to the impact, the most favorable orientation being an angle to the collision axis at which there is at least one of (i) a least likelihood of injury to the passenger in the seat or (ii) a highest performance of a personal restraint system.

20. The medium of claim 19 , wherein the method further comprises determining the most favorable orientation of the seat in the vehicle based on the location and the collision axis.
