Abstract

Inflatable restraint assemblies for use with removable vehicle components allow portions of inflator assemblies to remain in the vehicle when the component is removed. The assemblies may include inflatable devices such as an airbag mounted within a removable seat with conduit connecting the inflatable device to a seat connection. The seat connection may be adapted to connect to an inflator connection that is connected to an inflator assembly within the vehicle. Such assemblies allow the inflatable device to be in fluid communication with the inflator assembly when in an installed position, and to allow the inflator assembly to remain attached within the vehicle when the seat is in a removed position.

Claims

1. A removable vehicle seat assembly comprising:

a seat having a seat base and a seat back, the seat being configured for selective removal from and attachment to a vehicle;

an inflatable device mounted to the seat, the inflatable device being configured to remain mounted to the seat when the seat is removed from the vehicle; and

a seat connector configured for operative connectivity with an inflator device located outside of the seat and within the vehicle to permit fluid communication between the inflator device and the inflatable device when the seat is in an attached position.

2. The removable vehicle seat assembly of claim 1, wherein the inflatable device comprises a side airbag mounted within the seat back.

3. The removable vehicle seat assembly of claim 1, wherein the inflatable device comprises one of an inflatable seat belt or active headrest.

4. The removable vehicle seat assembly of claim 1, wherein the inflator device is located within a floor of the vehicle.

5. The removable vehicle seat assembly of claim 1, wherein the inflator device is located above a top surface of a floor of the vehicle within floor tracks that may selectively move with respect to the floor.

6. The removable vehicle seat assembly of claim 1, further comprising a conduit connected in fluid communication with the inflatable device and the seat connector.

7. The removable vehicle seat assembly of claim 6, wherein the seat connector is located near a bottom portion of the seat base.

8. The removable vehicle seat assembly of claim 7, wherein the seat connector is configured to engage with an inflator connector located near a floor surface of the vehicle, the inflator connector being in fluid communication with the inflator device.

9. An inflatable restraint assembly comprising:

a removable vehicle component configured for selective attachment and detachment from an interior portion of a vehicle;

an inflatable restraint operatively connected with the removable vehicle component; and

an inflator device located outside of the removable vehicle component and within the vehicle,

the inflatable restraint being in position for fluid connectivity with the inflator device when the removable vehicle component is in an attached position, and

the inflator device including a valve configured to allow one-way fluid passage, the valve including a burst disc located in an inflator outlet tube.

10. An inflatable restraint assembly comprising:

a removable vehicle seat configured for selective removal from and attachment to an interior portion of a vehicle;

an inflatable restraint mounted to the removable vehicle seat, the inflatable device being configured to remain mounted to the removable vehicle seat when removed from the interior portion of the vehicle;

a conduit connecting the inflatable restraint in fluid communication to a seat connector;

an inflator device located within the interior portion of the vehicle; and

an inflator connector in fluid communication to the inflator device,

wherein the seat connector engages the inflator connector in fluid communication when the removable vehicle seat is in an attached position.

11. The inflatable restraint assembly of claim 10, wherein the inflatable restraint comprises a side airbag mounted within a seat back of the removable seat.

12. The inflatable restraint assembly of claim 11, wherein the inflator device is located within a floor assembly of the interior portion of the vehicle.

13. The inflatable restraint assembly of claim 11, wherein the conduit comprises tubing connecting the side airbag and the seat connector.

14. The inflatable restraint assembly of claim 10, wherein the seat connector is located near a bottom portion of a seat base, and wherein the seat connector is in fluid connection with the inflator connector when the vehicle seat is in the attached position.

15. The inflatable restraint assembly of claim 10, wherein the inflator device further comprises a valve configured to allow one-way fluid passage.

16. The inflatable restraint assembly of claim 15, wherein the valve comprises a burst disc located in an inflator outlet tube.

17. The inflatable restraint assembly of claim 10, wherein the conduit comprises tubing connected to the inflatable restraint and the seat connector.
