Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a roof rack for a vehicle, and more particularly to a structure suitable for mounting a roof rack on a vehicle roof having a fixed roof such as a sedan or van.

[0002]

2. Description of the Related Art For example, in order to mount a roof rack on a roof of a sedan, a mounting bracket having a hook which can be hooked on an open end of a drip channel provided on the roof is usually used.

[0003]

The drip channel serves as a gutter for guiding rainwater on the roof in the front-rear direction of the vehicle body, and is not for supporting a load, so that a relatively light load is placed on the roof rack. Suitable for the case. Therefore, there is a case where a roof rail is separately attached to a roof and a roof rack is attached using the roof rail so that even heavy loads can be loaded.

[0004] The present invention provides a structure for mounting a roof rack for an automobile, in which a roof rack is mounted using a roof rail.

[0005]

SUMMARY OF THE INVENTION The present invention is a structure for mounting an automobile roof rack on a roof, comprising a roof rail, a mounting fixture, and a fixture. The roof rail includes a mounting piece attached to each side of the roof so as to extend in the front-rear direction of the vehicle body, two space forming pieces extending upward from both side ends of the mounting piece, and a vehicle body extending from the upper end of these space forming pieces. And two top pieces extending so as to approach each other in the width direction and creating a gap between opposing ends. The attachment includes a contact piece that contacts the top piece above the two top pieces, and two restraining pieces that extend downward from both side ends of the contact piece so as to cover at least a part of the gap forming piece. And connected to the roof rack. The fixture includes a crimp plate disposed within the roof rail and in contact with the top piece below the top piece to secure the fixture to the roof rail.

[0006]

[Function and effect] When a roof rack should be installed,
The crimp plate of the fixture is placed in the roof rail, the fixture is placed on the roof rail, and the fixture is attached to the roof rail by the fixture. The roof rack is connected to a fixture.

[0007] A roof rail is provided separately, and since the strength and shape of the roof rail can be selected independently of the parts or members of the automobile, a heavy load can be roofed compared to the mounting structure using a drip channel. Can be mounted on a rack.

In the mounted state, the two top pieces of the roof rail are sandwiched between the crimp plate of the fixture and the contact piece of the fixture, and the two restraining pieces of the fixture extend downward from the contact piece, and Since at least a part of the interval forming piece is covered, a firm attachment can be achieved. That is, even if the top piece of the roof rail attempts to open upward due to the load applied from the roof rack, the restraining piece of the fixture extending downward covers the spacing forming piece on the side of the roof rail top piece and restrains it. Therefore, the opening of the top piece can be suppressed, and the crimping plate can be prevented from coming off the roof rail.
