A roof bar (10) for a motor vehicle (1) is disclosed in which an elongate load carrying member (313) is selectively held in a deployed position by a latch mechanism (320). The latch mechanism (320) interacts directly with the elongate load carrying member (313) and no separate stay is required to hold the elongate load carrying member (313) in the deployed position. The components (311, 315, 316)forming the roof bar (10) are all relatively thin when the roof bar (10) is in the stowed state so as to minimise any change in vehicle height.
