| 摘要 |
The invention relates to a roof-rack bar for automobile vehicles comprising a transverse bar and two fastening feet mounted at the ends of the transverse bar. The feet operate in conjunction with side rails mounted on an automobile vehicle, wherein the feet can slide along the side rails during adjustment. The angle between the transverse bar and each of the side rails remains substantially constant when the bar is displaced. At least one of the feet includes a housing in which one end of the transverse bar can slide between two extreme positions in order to adapt to a variable distance between non-parallel side rails. This housing includes a first locking and reinforcement means capable of operating in conjunction with a second locking and reinforcement means fitted on the transverse bar to immobilize or authorize the displacement of the end of the transverse bar in the housing.
