Seatbelt apparatus

1. A seatbelt apparatus comprising:

a seatbelt having a tongue;

a buckle device having a buckle section configured to engage with the tongue, the buckle device further having a switch configured to sense engagement between the buckle section and the tongue, wherein the buckle section includes an enclosure;

a wire configured to fix the buckle device to a vehicle body;

a protective cover, covering an outer side of the wire so as to house the wire;

a signal cable connected to the switch and extending on an inner side of the protective cover;

a holder located on the inner side of the protective cover and fitted on the outer side of the wire; and

a wheel configured to connect the seatbelt apparatus to a vehicle frame or a vehicle seat;

wherein ends of the wire are mounted in the enclosure of the buckle section;

wherein the wire is folded about the wheel so that the wire is pivotably secured via the wheel.

2. The seatbelt of claim 1 , wherein the wire has a first portion and a second portion;

wherein the first portion includes the ends of the wire and is covered by the enclosure;

wherein the second portion of the wire is configured to bend, wherein the wire is pivotally supported by the wheel and a fixed member; and

wherein the protective cover is accordion shaped and is configured to support the enclosure on the frame or a side of the seat, and is configured to rotate with respect to the seat.

3. The seatbelt of claim 2 , wherein the holder is fitted on the wire at a constricted portion of the protective cover adjacent the fixed member.

4. The seatbelt of claim 1 , further comprising:

a tape wound around the holder and wire so as to at least partially cover the holder and the wire, thereby affixing the holder to the wire.

5. The seatbelt of claim 1 , wherein the holder is located at a fixed position relative to the wire.

6. The seatbelt of claim 1 , wherein the holder is located proximate to a constricted portion of the protective cover.

7. The seatbelt assembly of claim 1 , wherein the wire and the wheel are supported by a fixed member that is configured to be coupled to a vehicle frame or a vehicle seat, wherein the holder is located adjacent to the fixed member.

8. The seatbelt assembly of claim 1 , wherein the wire comprises a looped portion that is wrapped around the wheel.

9. The seatbelt assembly of claim 1 , wherein the protective cover includes a constricted portion.

10. A seatbelt assembly for use in a motor vehicle, comprising:

a seatbelt;

a tongue slidably attached to the seatbelt; and

a buckle configured to engage the tongue;

a wire configured to connect the buckle to the vehicle;

an enclosure covering the buckle and ends of the wire mounted in the enclosure;

a holder located within the enclosure and covering the wire to thereby provide additional rigidity to the wire when the enclosure is subject to a bending moment in a plane extending in the longitudinal direction of the vehicle; and

a wheel configured to connect the seatbelt assembly to a vehicle frame or a vehicle seat, wherein the wire is folded about the wheel so that the wire is pivotably secured via the wheel.

11. The assembly of claim 10 , wherein the wire comprises a plurality of overlapping portions.

12. The assembly of claim 10 , further comprising a buckle switch and a signal wire carrying a signal from the buckle switch to a controller, wherein the signal wire is contained within the enclosure.

13. The seatbelt assembly of claim 10 , wherein the enclosure is configured to rotate with respect to the fixed member.

14. The seatbelt assembly of claim 10 , wherein the wire comprises a looped portion that is wrapped around the wheel.

15. The seatbelt assembly of claim 10 , further comprising tape configured to secure the wire to the holder.

16. The seatbelt assembly of claim 10 , wherein the holder is located at a fixed position relative to the wire.

17. The seatbelt assembly of claim 10 , wherein the holder is located proximate to a constricted portion of the enclosure.

18. The seatbelt assembly of claim 10 , wherein the wire is supported by a fixed member that is configured to be coupled to a vehicle frame or a vehicle seat, wherein the holder is located adjacent to the fixed member.

19. The seatbelt assembly of claim 10 , wherein the protective cover includes a constricted portion.
