A roof structure is disclosed for a vehicle that comprises a roof bow including a wall forming part of an exterior roof surface of the vehicle. The wall defines a keyhole opening that is adapted to receive a retainer. A channel is provided on the wall below the keyhole opening that forms a water drain below the keyhole opening with a lower surface of the wall extending over the water drain. A retainer including an anchor portion and an accessory attachment portion extends upwardly from the anchor portion through the slot and is retained in the channel by the flanges.

A vehicle roof panel attachment assembly includes a substructure, a fastening device, a roof panel, and a side panel. The fastening device is engaged to the substructure and projects through an opening in the substructure. The roof panel includes a top portion spaced above the substructure, a flange, and a bend feature disposed between the top portion and the flange. The flange projects, at least in-part, downward from the bend feature and is engaged to the fastening device. The side panel includes an outer segment and an inner segment projecting, at least in-part, downward from the outer segment. A seam is carried by and between the bend feature and the inner segment.

The invention relates to a rooftop crossmember (31) structurally bridging rooftop side members (32) at an end of a rooftop (11) of a railway passenger car (2, 3) adjacent to a gangway bellow (4) and comprising a plurality of structural elements such as an upper structural element (40a) and a lower structural element (40b). The lower and upper structural elements (40a, 40b) are shaped and attached together for forming a hollow structure integrating means for performing non-mechanical functions such as a water drainage channel (34) for evacuating water accumulating on the rooftop (11) on the top part of said gangway bellow (4), and at least an electric housing (29).

A roof system for a motor vehicle including a support frame which supports at least one roof element, and drainage system which has at least one water gutter. The water gutter is provided at least over part of its length with a plurality of anti-surge bodies which are spaced apart from one another in the longitudinal direction of the water gutter, are each extended over a partial region of a width and/or a height of the water gutter and leave free at least a partial portion of a base of the water gutter.

A vehicle includes a roof ditch extending longitudinally, a first trim component covering a first portion of the roof ditch, a hinge mounted to a second portion of the roof ditch and connected to a liftgate, and a second trim component supported for pivotal movement. The second trim component covers the second portion of the roof ditch and at least a portion of the hinge. The roof ditch is formed by layers including at least one of a roof, a body side, and a reinforcement. The first trim component may be a molding and/or a roof rail covering the first portion of the roof ditch. A related method of adjusting a liftgate includes the steps of applying a force to a first end of a trim component in a closed position sufficient to overcome a holding force of a fastener, pivoting the first end of the trim component to an open position to reveal a hinge fastened to a roof ditch and the liftgate, loosening at least one fastener, adjusting the liftgate, tightening the at least one fastener, and returning the trim component to the closed position.

A vehicle includes a vehicle body comprising a pillar having a pillar channel extending therethrough. A pillar channel seal includes a seal body located in the pillar channel. The seal body has a pass-through opening sized to receive a drain hose. A moveable plug is movably attached to the seal body that is configured to cover the pass-through opening in a closed configuration. An expandable foam is carried by the moveable plug.
