RETENTION HINGE COMPONENT, IN PARTICULAR FOR MAINTAINING AN EXTERNAL REARVIEW MIRROR OF A UTILITY VEHICLE AND EXTERNAL REARVIEW MIRROR FOR A UTILITY VEHICLE COMPRISING SAID TYPE OF RETENTION HINGE COMPONENT

摘要

The invention relates to a retention hinge component, the overall height thereof being smaller in the direction of the retention hinge axis (13). The invention also relates to an external rearview mirror comprising said type of retention hinge component provided with a first and a second retention arm (4, 6) which are connected together in a pivotable manner by a hinge axis component (8, 10, 12). The first retention arm comprises a first and a second retention arm part (14, 18), the joining surfaces (24, 26) being assembled in a complementary manner thus allowing forces to be transmitted in a uniform manner from one retention arm to the second retention arm via the hinge axis component. A sandwich structure is produced by the two-part first retention arm, which enables, counter to the two-part retention arm cited in EP 527 455 B1 or in GB 658 679 A, force to be transferred from the retention axis component to the first retention arm via its entire surface associated with each other. Force is applied from both maintaining parts to the remaining part of both retention arm parts. As a result, forces applied to the motor vehicle external rearview mirrors are transferred in a safe manner due to the overall height of the retention hinge component being essentially reduced.
