Abstract

A plurality of pads are configured to be arranged in a vehicle seat. A plurality of passive movement devices are provided to be respectively arranged behind, and to cause movement of, the plurality of pads. The passive movement devices are configured to be actuated independently of one another.

First claim

The invention claimed is:

1. A system, comprising:
a plurality of pads configured to be arranged on a vehicle seat;
a plurality of passive movement devices respectively arranged behind, and to cause movement of, the pads;
wherein the passive movement devices are configured to be actuated independently of one another and each one of the plurality of pads is configured to move independently of one another upon actuation of the passive movement devices.

2. The system of claim 1 , further comprising a controller that includes a processor and a memory, the memory storing instructions executable by the processor to actuate at least one of the passive movement devices.

3. The system of claim 2 , wherein the memory further stores instructions executable by the processor to receive data from at least one impact sensor, and to use the received data in determining to actuate at least one of the passive movement devices.

4. The system of claim 3 , wherein the memory further stores instructions executable by the processor to actuate only one of the passive movement devices based on the received data.

5. The system of claim 1 , wherein the passive movement devices include one of an airbag, a plastic bladder, and a motor.

6. The system of claim 1 , wherein the passive movement devices are arranged to move the pads vertically, the system further comprising at least one horizontal movement device, wherein each at least one horizontal movement device is arranged to move a respective one of the pads horizontally.

7. The system of claim 6 , wherein each at least one horizontal movement device includes a stored energy device that is arranged to release a horizontal movement mechanism.

8. The system of claim 7 , further comprising a controller that includes a processor and a memory, the memory storing instructions executable by the processor to actuate at least one of the passive movement devices and the stored energy device.

9. The system of claim 1 , wherein the seat includes a lower seat portion, a lumbar seat portion, an upper seat portion, and a head restraint.

10. The system of claim 9 , wherein the lower seat portion includes a first pad, a second pad, a first passive movement device arranged behind the first pad, and a second passive movement device arranged behind the second pad.

11. The system of claim 9 , wherein the lumbar seat portion includes a first pad, a second pad, a central pad, a first passive movement device arranged behind the first pad, a second passive movement device arranged behind the second pad, and a central passive movement device arranged behind the central pad.

12. The system of claim 9 , wherein the upper seat portion includes an upper pad, the head restraint includes a head restraint pad, and an upper seat passive movement device is arranged behind the upper pad.

13. A method, comprising:
using data relating to an impact to determine to actuate at least one of a plurality of passive movement devices that are respectively arranged behind, and to cause movement of, a plurality of pads in a vehicle seat; wherein the passive movement devices are configured to be actuated independently of one another and each one of the plurality of pads is configured to move independently of one another upon actuation of the passive movement devices.

14. The method of claim 13 , further comprising actuating the plurality of passive movement devices based on the received data.

15. The method of claim 13 , wherein the passive movement devices are arranged to move the pads vertically, the method further comprising, based on the data relating to the impact, moving at least one horizontal movement device that is arranged to move a respective one of the pads horizontally.

16. The method of claim 15 , wherein each at least one horizontal movement device includes a stored energy device that is arranged to release a horizontal movement mechanism, the method further comprising actuating at least one of the passive movement devices and the stored energy device.

17. A controller that includes a processor and a memory, the memory storing instructions executable by the processor, including instructions to:
use data relating to an impact to determine to actuate at least one of a plurality of passive movement devices that are arranged behind, and to cause movement of, a plurality of pads in a vehicle seat; wherein the passive movement devices are configured to be actuated independently of one another and each one of the plurality of pads is configured to move independently of one another upon actuation of the passive movement devices.

18. The controller of claim 17 , the instructions further including instructions to actuate the passive movement devices based on the received data.

19. The controller of claim 17 , wherein the passive movement devices are arranged to move the pads vertically, the instructions further including instructions to, based on the data relating to the impact, move at least one horizontal movement device that is arranged to move a respective one of the pads horizontally.

20. The controller of claim 19 , wherein each at least one horizontal movement device includes a stored energy device that is arranged to release a horizontal movement mechanism, the instructions further including instructions to actuate at least one of the passive movement devices and the stored energy device.
