Abstract: A load carrier for vehicles has two longitudinal load supports adapted to be fixed to a roof of a vehicle and transverse load supports which are movably disposed between the longitudinal supports. One end of a transverse load support is pivotally connected to a movable joint provided in each of the longitudinal load supports and a movable locking member is provided in the opposing longitudinal support. The transverse load supports may be folded into the longitudinal load supports when not in use, and pivoted to a load carrying position extending between longitudinal supports and secured by the locking member. The load carrying position of the transverse load supports along the longitudinal supports may be changed by moving the joint and locking members.
