  • the socket 1022 can cause torque variation due to high finger stiffness. Torque is therefore sensitive to dimensional variations. However, the fingers 1032, 1034 cannot all be flexible or the mount system may result in poor vibration performance under dynamic loads. Thus, the socket 1022 can be configured to reduce the stiffness of one or more of the fingers 1032, 1034, while increasing a pre-deflection result in the same torque value with lower stiffness.

  • the band spring 1024 can be applied around the fingers 1032, such that the fingers 1032 apply a force on the ball or split ball. The compressive force, together with the friction between the socket 1022 and the ball, provide a torque-resisting motion between the ball and the socket 1022.

  • the band spring 1024 can contact four fingers 1032, 1034 to create a static determinate system, according to one embodiment. Stress can be reduced during assembly of the support 1004 and the ball into the socket 1022 because the flexible fingers have little or no deflection.
  • the flexible fingers 1032 can include a positive stop that can be used to locate the band spring 1024. Having the one or more ribs 1036 on one of the stiff fingers 1034 can be adapted to provide a positive location feature.
  • stiff fingers 1034 are configured to provide enhanced rigidity and vibration performance.
  • the force can be distributed on any of between four to eight fingers 1032, 1034, depending on tolerance variation of the band spring 1024 and the socket 1022. Over time, the fingers 1032, 1034 experiencing higher force will creep more, changing the shape of the fingers 1032, 1034. At the same time, force is lost from the band spring 1024. Since the amount of force on each individual finger 1032, 1034 determines the mirror adjustment torque normal to that finger 1032, 1034, redistribution of these normal forces will change the adjustment torque differently in all eight directions.

  • the first distinct socket portion 1208 and the second distinct socket portion 1210 are mirror images of each other and can be connected by other methods than mechanical fasteners (e.g., vibration weld, spin weld, or sonic weld).
  • first and second distinct socket portions 1208, 1210 can be held together by the band spring 1024.
  • the first distinct socket portion 1208 and the second distinct socket portion 1210 are then positioned around the ball 1204 and connected at first and second fastener locations.
  • an interference fit is provided between a male protrusion 1220 and a female receiver 1222 at each of the first and second fastener locations.
  • a band spring 1230 is then positioned around the ball receiving wall 1211, and more specifically around a plurality of fingers 1232 that are disposed around the ball receiving wall 1211.
  • the band spring 1230 is generally configured to extend about the periphery of the ball receiving wall 1211 in abutting contact with the plurality of fingers 1232 and force the ball receiving wall 1211 inward into frictional contact with the ball 1204.
  • the ball 1204 is then operably coupled with a neck 1216 of the support 1202.
  • the cavity 1212 generally defines an internal wire aperture 1234 for routing power and data lines through both the split socket 1206 and the ball 1204, and into the mount system 1200.
  • the split socket 1206 generally includes first and second retention members 1240, 1242 designed to retain the ball 1204 in the split socket 1206.
  • the ball receiving wall 1211 and the plurality of fingers 1232 are generally configured to flex under pressure or force applied by the band spring 1230, thereby providing a selective force on the ball 1204, which affects the torsional properties between the ball 1204 and the split socket 1206. Accordingly, the retention and adjustment torque on a rearview device connected with the mount system 1200 can be modified by using different band springs 1230.
  • the term "coupled” in all of its forms, couple, coupling, coupled, etc. generally means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally formed as a single unitary body with one another or with the two components. Such joining may be permanent in nature or may be removable or releasable in nature unless otherwise stated.
