Abstract

In a buckle device, cord portions that are pulled out from a distal end portion in a longitudinal direction of a helical portion of a curl cord are electrically and mechanically connected to a terminal of a buckle switch of a buckle. The distal end portion in the longitudinal direction of the helical portion of the curl cord is held by a holding bracket that is provided at a first cover component of a buckle cover. Consequently, even when the buckle cover is moved, excellent connections can still be maintained between the cord portions of the curl cord and the terminal of the buckle switch of the buckle.

First claim

What is claimed is:

1. A buckle device comprising:
a buckle with which a tongue of a seatbelt device is engaged, and that is able to move relative to a vehicle body;
a cord member whose distal end portion in a longitudinal direction is connected to the buckle; and
a distal end side holding section that is provided so as to be able to move together with the buckle, and that holds a part of the cord member, which part is at further toward a base end side in the longitudinal direction of the cord member than the distal end portion of the cord member, such that, when the buckle moves relative to the vehicle body, the distal end of the cord member is configured to move together with the buckle relative to the vehicle body,
wherein the cord member is mechanically and electrically connected to the buckle.

2. The buckle device of claim 1 , wherein an expanding and contracting portion that is part of the cord member and is able to expand and contract in the longitudinal direction of the cord member is provided at the cord member at a side which is further toward the base end side in the longitudinal direction of the cord member than the distal end portion the cord member, and the distal end side holding section holds a distal end portion in a longitudinal direction of the expanding and contracting portion.

3. The buckle device of claim 2 , wherein the expanding and contracting portion is formed in a helical shape whose central axis is aligned with the longitudinal direction of the cord member, and is able to expand and contract elastically in a direction of the central axis.

4. The buckle device of claim 3 , wherein the distal end side holding section comprises: an inner side holding portion that is engaged with the expanding and contracting portion from an inner side in a radial direction of a helix of the expanding and contracting portion; and an outer side holding portion that is engaged with the expanding and contracting portion from an outer side in a radial direction of the helix of the expanding and contracting portion, and that, together with the inner side holding portion, holds the expanding and contracting portion.

5. The buckle device of claim 3 , further comprising:
a supporting portion that is provided at a vehicle body side, and by which the buckle is movably supported; and
a base end side holding section that is provided at the supporting portion, and that holds a base end portion in the longitudinal direction of the expanding and contracting portion.

6. The buckle device of claim 4 , further comprising:
a supporting portion that is provided at a vehicle body side, and by which the buckle is movably supported; and
a base end side holding section that is provided at the supporting portion, and that holds a base end portion in the longitudinal direction of the expanding and contracting portion.

7. The buckle device of claim 2 , wherein the distal end portion of the cord member, which is connected to the buckle, extends from the distal end portion of the expanding and contracting portion toward a distal end side of the cord member.

8. The buckle device of claim 3 , wherein the distal end portion of the cord member, which is connected to the buckle, extends from the distal end portion of the expanding and contracting portion toward a distal end side of the cord member.

9. The buckle device of claim 1 , wherein the distal end portion of the cord member and the buckle are configured to move relative to the base end side of the cord indirectly connected to the vehicle body.

10. The buckle device of claim 1 , wherein the buckle device further comprises
a moving member at which the buckle is provided and which is configured to move relative to the vehicle body, and
the distal end side holding section is fixed at the moving member.

11. The buckle device of claim 1 , wherein when the buckle moves relative to the vehicle body, the distal end side holding section, a moving member at which the buckle is provided, the buckle, and the distal end portion of the cord member are configured to all move together relative to the vehicle body.
