Abstract
A roller D-ring for a seat belt of a vehicle including a cylindrical roller, and a body having a folded structure to hold the roller by a folding portion of the body while allowing the roller to be rotatable. The folded structure is formed in a state in which the roller is seated on the folding portion of the body. The body defines, together with a peripheral surface of the roller, a gap, through which a webbing of the seat belt passes. Since the roller D-ring includes only two constituent elements, that is, the body and the roller, it is possible to reduce the manufacturing costs in accordance with a reduced number of constituent elements.

A roller D-ring for a seat belt of a vehicle comprising:
- a cylindrical roller;
- and
- a body having a folded structure to hold the roller by a folding portion of the body while allowing the roller to be rotatable, the folded structure being formed in a state in which the roller is seated on the folding portion of the body, the body defining, together with a peripheral surface of the roller, a gap, through which a webbing of the seat belt passes,
- wherein the body comprises a pair of closing sections that come into close contact with each other when the folded structure is completely formed, and a single opening provided between the pair of closing sections, to which the peripheral surface of the roller is exposed, the single opening being substantially symmetrical with respect to both an axis of the roller and a central line crossing the closing sections, such that when the body is folded so that the closing sections contact each other, a pair of spaced apart holding sections each formed at opposite sides of the single opening are entirely spaced apart by the single holding opening;
- the roller including a roller body and a plurality of rolling sections provided on opposite ends of the roller body;
- a diameter of at least one of the rolling sections is smaller than a diameter of the roller body;
- and the rolling sections are formed unitarily and in one-piece at the opposite ends of the roller body.
A method for assembling a roller D-ring for a seat belt of a vehicle, comprising:
- forming a flat-sheet-shaped D-ring body having a pair of closing sections;
- forming a single opening provided between the pair of closing sections, to which the peripheral surface of a roller is exposed, the single opening being substantially symmetrical with respect to both an axis of the roller and a central line crossing the closing sections;
- bending the flat-sheet-shaped D-ring body about a folding portion of the flat-sheet-shaped D-ring body through an angle predetermined to provide a seat, on which the roller is to be seated;
- forming a roller body and a plurality of rolling sections unitarily and in one-piece on opposite sides of the roller body, a diameter of each rolling section being smaller than a diameter of the roller body;
- and
- inserting the roller into the bent body such that the roller is seated on the seat;
- and
- folding the flat-sheet-shaped D-ring body about the folding portion of the flat-sheet-shaped D-ring body body such that the closing sections contact each other, and a pair of spaced apart holding sections each formed at opposite sides of the single opening are entirely spaced apart by the single opening.
