Abstract

A seat assembly includes a seatback having a back support portion centrally disposed thereon. A retractor mechanism is operably coupled to the seatback. A belt member is coupled to the retractor mechanism. The belt member further includes a body portion disposed between first and second ends of the belt member. The body portion of the belt member is operable between a stowed position and a deployed position. The belt member is disposed in front of the back support portion of the seatback in the deployed position. The belt member is disposed in an interior portion of the seatback in the stowed position. The seat assembly further includes an airbag assembly to which the belt member is attached. The belt member is deployed when the airbag assembly is deployed as coupled thereto.

First claim

What is claimed is:

1. A seat assembly, comprising:
a seatback having a back support portion centrally disposed thereon;
at least one retractor mechanism operably coupled to the seatback and having first and second attachment locations spaced-apart from one another;
wherein the at least one retractor mechanism includes first and second retractor mechanisms with the first attachment location disposed on the first retractor mechanism and the second attachment location disposed on the second retractor mechanism;
a belt member having first and second ends respectively coupled to the first and second attachment locations of the at least one retractor mechanism, wherein the belt member further includes a body portion disposed between the first and second ends that is operable between a deployed position, wherein the belt member is disposed in front of the back support portion of the seatback, and a stowed position, wherein the belt member is received in the seatback; and
a slider mechanism coupled to one of the first retractor mechanism and the second retractor mechanism to define a slideable retractor mechanism operative for movement between first and second positions, wherein movement of the slideable retractor mechanism from the first position to the second position is operative to retract the belt member from the deployed position.

2. The seat assembly of claim 1 , wherein the first and second attachment locations are disposed on opposite sides of the back support portion.

3. The seat assembly of claim 1 , including:
an airbag assembly supported in an interior portion of the seatback in a stowed position, wherein the airbag assembly is configured to deploy from the stowed position to a deployed position in a seat-forward direction around the back support portion of the seatback.

4. The seat assembly of claim 3 , wherein the body portion of the belt member is operably coupled to the airbag assembly for deployment therewith.

5. The seat assembly of claim 4 , wherein the seatback includes a headrest assembly disposed above the back support portion, and further wherein the airbag assembly is disposed on opposed sides of the back support portion of the seatback and is further disposed over the headrest assembly of the seatback in the stowed position.

6. The seat assembly of claim 5 , wherein the body portion of the belt member is disposed on the opposed sides of the back support portion of the seatback and is further disposed over the headrest assembly of the seatback in the stowed position.

7. A seat assembly, comprising:
a seatback having an interior portion;
a belt member having first and second ends with a body portion disposed therebetween, wherein the belt member is operable between a stowed position wherein the body portion of the belt member is received within the interior portion of the seatback, and a deployed position wherein the body portion of the belt member is positioned outside of the interior portion of the seatback;
a retractor mechanism coupled to one of the first end and the second end of the belt member; and
a slider mechanism, wherein the retractor mechanism is slideably supported on the slider mechanism for movement between a plurality of positions.

8. The seat assembly of claim 7 , including:
a retractor mechanism operably coupled to one of the first end of the belt member, the second end of the belt member, and a combination thereof.

9. The seat assembly of claim 8 , wherein the retractor mechanism is disposed within the interior portion of the seatback.

10. The seat assembly of claim 7 , including:
an inflatable member disposed on the body portion of the belt member and operable between inflated and deflated conditions.

11. The seat assembly of claim 7 , including:
an airbag assembly supported in the interior portion of the seatback in a stowed position, wherein the airbag assembly is configured to deploy in a seat-forward direction to a deployed position, wherein the airbag assembly is disposed around a centrally disposed back support portion of the seatback in the deployed position.

12. The seat assembly of claim 11 , wherein the body portion of the belt member is operably coupled to the airbag assembly for deployment therewith.

13. A seat assembly, comprising:
a belt member spanning between opposed sides of a seatback and operable between stowed and deployed positions;
a retractor mechanism operably coupled to the belt member and operative to retract the belt member from the deployed position;
an inflatable member disposed on the belt member and operable between inflated and deflated conditions; and
a slider mechanism, wherein the retractor mechanism is slideably supported on the slider mechanism for movement between a plurality of positions.

14. The seat assembly of claim 13 , including:
an inflator mechanism configured to inflate the inflatable member to the inflated condition during a deployment of the belt member.

15. The seat assembly of claim 14 , wherein the inflatable member includes a first width in the deflated condition, and further wherein the inflatable member includes a second width in the inflated condition that is greater than the first width.

16. The seat assembly of claim 13 , including:
an airbag assembly supported in an interior portion of the seatback in a stowed position, wherein the airbag assembly is configured to deploy in a seat-forward direction to a deployed position, wherein the airbag assembly is disposed around a centrally disposed back support portion of the seatback in the deployed position.

17. The seat assembly of claim 16 , wherein the belt member is operably coupled to the airbag assembly.
