Abstract
A reinforcement rail for a roof side rail according to the present disclosure includes a first section having a predetermined thickness, a second section extending toward a lower side of a vehicle from an end of the first section based on a direction toward the outside of the vehicle, and a third section extending toward the lower side of the vehicle from an end of the first section based on a direction toward the inside of the vehicle, the third section being connected to a lower end of the second section, and the first section, the second section, and the third section define a closed cross-section.
Claims18
A rail for a vehicle, comprising:
- a reinforcement rail between a roof side rail and a roof side reinforcement of the vehicle, wherein the reinforcement rail is disposed in a longitudinal direction of the vehicle;
- a cross-section of the reinforcement rail, wherein:
- the cross-section is perpendicular to the longitudinal direction of the vehicle,
- the cross-section is a closed cross-section having a hollow portion therein, and
- a thickness of the cross-section of the reinforcement rail varies along a periphery of the reinforcement rail,
- wherein:
- the reinforcement rail comprises:
- a first section having a predetermined thickness;
- a second section extending toward a lower side of the vehicle from a first end of the first section based on a first direction toward an outside of the vehicle;
- and
- a third section extending toward the lower side of the vehicle from a second end of the first section based on a second direction toward an inside of the vehicle,
- the third section is connected to a first lower end of the second section, and
- the first section, the second section, and the third section define the closed cross-section.
A roof side rail assembly, comprising:
- a roof side rail disposed at each of two opposite ends of a roof panel of a vehicle and provided in a longitudinal direction of the vehicle, the roof side rail being joined to a roof side inner part and a roof side outer part;
- a roof side reinforcement joined to an inner side of the roof side rail;
- and
- a reinforcement rail between the roof side rail and the roof side reinforcement and having a hollow cross-section, the reinforcement rail extending in the longitudinal direction of the vehicle and coupled to at least any one of the roof side rail and the roof side reinforcement,
- wherein:
- the reinforcement rail comprises:
- a first section having a predetermined thickness;
- a second section extending toward a lower side of the vehicle from a first end of the first section based on a first direction toward an outside of the vehicle;
- and
- a third section extending toward the lower side of the vehicle from a second end of the first section based on a second direction toward an inside of the vehicle,
- the third section is connected to a first lower end of the second section, and
- a cross-section of the reinforcement rail, which is perpendicular to the longitudinal direction of the vehicle, is a closed cross-section closed by the first section, the second section, and the third section.
