Abstract

A buckle presenter for moving a seat belt buckle with a vehicle seat of a vehicle is provided. The vehicle seat has a seat frame connected to a seat adjustment mechanism that moves the vehicle seat. The buckle presenter includes an anchor strap and a buckle strap. The anchor strap is anchored with respect to the vehicle seat such that it is substantially restricted from moving when the vehicle seat is being adjusted vertically. The buckle is attachable to the buckle strap, which is connectable to the vehicle seat such that it moves with the vehicle seat when it is being adjusted vertically. The buckle strap is configured to move along the anchor strap. When a load is applied to the seat belt buckle, the buckle strap and the anchor strap are configured to interlock such that the buckle strap is substantially restricted from moving vertically.

Claims

1. A buckle presenter for moving a seat belt buckle with a vehicle seat of a vehicle, the vehicle seat having a seat frame connected to a seat adjustment mechanism for moving the vehicle seat, the buckle presenter comprising:

an anchor strap that is anchored with respect to the vehicle seat such that the anchor strap is restricted from moving vertically when the vehicle seat is being adjusted vertically; and

a buckle strap to which the seat belt buckle is attachable, the buckle strap being connectable to the seat frame of the vehicle seat such that the buckle strap moves with the vehicle seat when it is being adjusted vertically, the buckle strap being configured to move along the anchor strap;

a housing configured to guide the buckle strap along the anchor strap when the vehicle seat is being adjusted vertically, wherein the housing is attachable to the seat frame;

wherein the anchor strap and the buckle strap are configured to interlock such that the buckle strap is substantially restricted from moving vertically when a load is applied to the seat belt buckle; and

wherein at least one of the buckle strap and the anchor strap comprises at least a portion of an interlocking mechanism configured to interlock the buckle strap and the anchor strap when the load is applied to the seat belt buckle, and the interlocking mechanism comprises at least one set of teeth on at least one of the anchor strap and the buckle strap.

2. The buckle presenter of claim 1 wherein the anchor strap comprises at least one translational stop to limit movement of the buckle strap along the anchor strap.

3. The buckle presenter of claim 1 further comprising an electronic wire to which the seat belt buckle is connectable, the electronic wire having a length that provides slack such that it extends when the seat belt buckle moves.

4. The buckle presenter of claim 1 further comprising at least one of a spacer and a spacing spring configured to maintain a distance between the buckle strap and the anchor strap in a normal position when the load is not applied to the seat belt buckle, and to enable the buckle strap to move such that it interlocks with the anchor strap when the load is applied to the seat belt buckle.

5. The buckle presenter of claim 4 wherein the at least one of the spacer and the spacing spring is configured to move back to the normal position when the load is removed from the seat belt buckle.

6. The buckle presenter of claim 1 further comprising an anchor to which the anchor strap is connected, the anchor strap being rotatable with respect to the anchor, and the anchor being connected to the seat adjustment mechanism such that the buckle presenter is movable longitudinally with the vehicle seat.

7. The buckle presenter of claim 6 wherein at least one of the anchor and the anchor strap has a rotational stop configured to limit rotation of the anchor strap.

8. A seat belt buckle assembly for a vehicle seat of a vehicle, the vehicle seat having a seat frame connected to a seat adjustment mechanism for moving the vehicle seat, the seat belt buckle assembly comprising:

a buckle; and

a buckle presenter having;

an anchor strap that is anchored such that the anchor strap is restricted from moving vertically when the vehicle seat is being adjusted vertically; and

a buckle strap to which the buckle is attachable, the buckle strap being connectable to the seat frame of the vehicle seat such that the buckle strap moves with the vehicle seat when it is being adjusted vertically, the buckle strap being configured to move along the anchor strap;

a housing configured to guide the buckle strap along the anchor strap when the vehicle seat is being adjusted vertically, wherein the housing is attachable to the seat frame;

wherein the anchor strap and the buckle strap are configured to interlock such that the buckle strap is substantially restricted from moving vertically when a load is applied to the buckle; and

wherein the buckle presenter further comprises at least one of a spacer and a spacing spring configured to maintain a distance between the buckle strap and the anchor strap when the load is not applied to the buckle, and to enable the buckle strap to move such that the buckle strap interlocks with the anchor strap when the load is applied to the buckle.

9. The seat belt buckle assembly of claim 8 wherein the buckle presenter further comprises an anchor to which the anchor strap is connected, the anchor strap being rotatable with respect to the anchor, and the anchor being connected to the seat adjustment mechanism such that the buckle presenter is movable longitudinally with the vehicle seat.

10. The seat belt buckle assembly of claim 8 wherein at least one of the buckle strap, the anchor strap, and the housing comprises at least a portion of an interlocking mechanism configured to interlock the buckle strap and the anchor strap when the load is applied to the buckle.

11. The seat belt buckle assembly of claim 10 wherein the interlocking mechanism comprises at least one set of teeth on at least one of the anchor strap and the buckle strap.

12. The seat belt buckle assembly of claim 8 wherein the buckle comprises a buckle switch, the buckle presenter further comprises an electronic wire connected to the buckle switch, and the electronic wire has a length that provides slack such that the electronic wire extends when the buckle moves.

13. The seat belt buckle assembly of claim 12 further comprising a seat attachment member defining an opening that enables rotation of the buckle strap.

14. The seat belt buckle assembly of claim 13 further comprising a spring insert disposed within the opening.

15. A seat assembly for a vehicle having a vehicle body, the seat assembly comprising:

a seat frame;

a seat adjustment mechanism attached to the vehicle body and to which the seat frame is attached, the seat adjustment mechanism being configured to adjust the seat frame in at least one of a longitudinal direction and a vertical direction; and

a seat belt buckle assembly having;

a buckle; and

a buckle presenter having;

an anchor strap that is anchored such that the anchor strap is restricted from moving vertically when the seat frame is being adjusted vertically; and

a buckle strap to which the buckle is attachable, the buckle strap being connectable to the seat frame such that the buckle strap moves with the seat frame when the seat frame is being adjusted vertically, the buckle strap being configured to move along the anchor strap;

a housing configured to guide the buckle strap along the anchor strap when the seat frame is being adjusted vertically, wherein the housing is attachable to the seat frame; and

an interlocking mechanism configured to interlock the buckle strap and the anchor strap when a load is applied to the buckle such that the buckle strap is substantially restricted from moving vertically when the load is applied to the buckle, wherein the interlocking mechanism comprises at least one set of teeth on at least one of the anchor strap and the buckle strap.
