Description

[Technical Field]

[0001] The present disclosure relates to a rearview device for a vehicle that includes an actuator. The present disclosure also relates to a vehicle that includes at least one such rearview device. [Background technology]

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] A vehicle requires an operable rear visibility system to provide a rearward visibility to the vehicle operator. The rear visibility system typically includes one or more components that must be actuated relative to the vehicle body along a first axis, and such components may include a mirror or a camera. As an example, actuation of the component along the first axis may provide the vehicle operator with the ability to fine-tune the rearward visibility provided by the rear visibility system.

[0004] Additionally, some rear visibility systems actuate one or more components along a secondary axis, which may include a mirror or a camera. As an example, actuation of a component along a secondary axis may cause the component to retract closer to the vehicle body under certain conditions. Generally, actuation of a component of a rear visibility system along a secondary axis is accomplished using a secondary actuator.

[0005] Electromechanical actuators are typically used to rotate components relative to the vehicle body, but existing electromechanical actuators are noisy, heavy, large, and subject the gear train to high shock loads during a crash, often requiring high-strength metal components (e.g., gears) that make the actuator heavy and expensive.

[0006] Using a single actuator to adjust components along multiple axes allows for adjustment along a second axis, reducing the design cost and complexity of rear visibility systems. Summary of the Invention

[0007] SUMMARY OF THE INVENTION It is an object of the present disclosure to provide a rearview vision system for a vehicle that overcomes the shortcomings of the prior art.

[0008] This object is achieved by a rear view device for a vehicle according to claim 1.

[0009] Embodiments of the rear vision device of the present disclosure are set out in dependent claims 2 to 25.

[0010] This object is also achieved by a vehicle equipped with at least one rear visibility device according to the present disclosure.

[0011] In general, the present disclosure provides a rearview mirror for a vehicle, the rearview mirror further comprising a mirror base providing a first mounting end for mounting to a side of the vehicle and a second mounting end for an actuator. The rearview mirror further comprises a mirror head including an actuator for moving the entire mirror head. To that end, the tilt axis of the actuator is configured to be fixedly mounted to the case bottom and / or case frame, and / or the hinge of the actuator is configured to be engaged by a complementary hinge of the case frame. Additionally or alternatively, the actuator is associated with a shroud for mounting the actuator such that the mirror head forms a seal. When the head is attached to the mirror base, an additional seal is created.

[0015] The following description is merely exemplary in nature and is in no way intended to limit the present disclosure, its application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding components and features.

[0016] FIG. 1 illustrates a vehicle 100 according to an embodiment of the present disclosure.

[0017] As shown in FIG. 1, a vehicle 100 includes rearview vision devices 102, 104 on either side of the vehicle. Although both 100 are illustrated as passenger cars, the vehicle 100 may be any other type of vehicle, and non-limiting examples of the vehicle 100 include a truck, an off-road vehicle, a bus, a motorcycle, an aircraft, a streetcar, a locomotive, or a large vehicle.

[0018] 1, the rearview mirror devices 102, 104 are shown as side view mirrors. In an alternative variation, the rearview mirror devices 102, 104 can be implemented as camera systems.

[0019] The rear vision devices 102, 104 are positioned on the vehicle 100 so as to be adjustable to provide the driver with a view behind the vehicle.

[0020] 2A-3C, the operation of the rearview vision devices 102, 104 will now be further described. Although the following description refers to the rearview vision device 104, it should be understood that the rearview vision device 104 has an analog structure.

[0021] 2A-2B show top views of a rearview vision device 102 according to an embodiment of the present disclosure.

[0022] As shown in FIGS. 2A-2B, the rearview vision device 102 includes a shaft 202, a mirror base 204, and a mirror head 206. In FIG. 2A, the rearview vision device 102 can be seen from a top-down view with the mirror head 206 in a driven position. When actuated in a first direction relative to the shaft 202, as indicated by line 208, movement is imparted to the mirror head 206, causing it to rotate about the shaft 202 to the retracted position, as indicated by line 208. Furthermore, when actuated in a second direction relative to the shaft 202, as indicated by line 208, movement is imparted to the mirror head 206 when in the retracted position, as indicated by line 208, causing it to rotate back to the driven position, as shown in FIG. 2A.

[0023] Actuation of the mirror head 206 about the axis 202 can occur from any position to move the mirror head 206 to any other position about the axis 202. For example, the mirror head 206 can start in a retracted position as shown in FIG. 2B and then be actuated in a second direction about the axis 202 to move the mirror head 206 to a driven position. The mirror head 206 can be adjusted to any position between the driven position shown in FIG. 2A and the retracted position shown in FIG. 2B.

[0024] 2A, actuation can be performed to move the mirror head 206 to adjust the rearward visibility of the driver of the vehicle 100. The movement required to adjust the mirror head 206 to adjust the rearward visibility of the driver of the vehicle 100 is less than the movement required to move the mirror head 206 from the drive position to the retracted position or from the retracted position to the drive position.

[0025] 3A-3C show side views of a rear visibility device 102 according to an embodiment of the present disclosure.

[0026] As shown in Figures 3A-3C, the rearview vision device 102 includes a mirror base 204, a mirror head 206, and a shaft 302. In Figure 3A, the rearview vision device 102 is seen in a side view with the mirror head 206 in a nominal position. When actuated in a first direction as indicated by line 304, the mirror head 206 is imparted with movement and tilted upward to the position shown in Figure 3B. When actuated in a second direction as indicated by line 304, the mirror head 206 is imparted with movement and tilted downward to the position shown in Figure 3C.

[0027] Actuation of the mirror head about axis 302 can be performed from any position to move the mirror head 206 to any other position about axis 302. For example, The actuator may begin tilting upward as shown in Figure 3B and then be actuated in a second direction to tilt the mirror head 206 downward. While tilting downward, the actuator may be stopped to adjust the mirror head 206 to the nominal position shown in Figure 3A, or the actuator may continue to adjust the mirror head 206 downward until it reaches the position shown in Figure 3C. Additionally, the mirror head 206 may be tilted to any position between Figures 3B and 3C.

[0028] It should be noted that although the following description and discussion of the figures will be directed to rear vision device 102, device 104 functions similarly.

[0029] 4 illustrates an actuator 402 according to an embodiment of the present disclosure. As shown in the figure, the actuator 402 includes an axis 202 and an axis 302. The axis 202 is substantially perpendicular to the axis 302. Furthermore, the axis 202 is substantially perpendicular to the actuator 402, and the axis 302 is substantially horizontal to the actuator 402.

[0030] Figure 5A shows an exploded view of the actuator 402 of Figure 4 according to an embodiment of the present disclosure. Figure 5B shows an additional exploded view of the actuator 402 according to an embodiment of the present disclosure.

[0031] 5A-5B, the actuator 402 further includes an upper housing 502, a lower housing 504, an interleaved hinge 506 providing one or more connection spaces between the two layers, a protrusion or the like, an opening 508, a tail pin 510, a connector 512, a camera mount 514, a fastener 516, a shroud 518, a protrusion 520, a guide 522, an additional fastener 528, an additional opening 530, a tilt axis 532, and a foot 534. The shroud 518 provides a spherical seat and further includes one or more clips 524, one or more guides 526, and yet another opening 536. The tilt axis 532 further includes an opening 538.

[0032] The upper housing 502 and the lower housing 504 are operable to house the internal components of the actuator 402. The upper housing 502 and the lower housing 504 are further operable to be joined or fastened together by fasteners 528. In this variation, the fasteners 528 are shown as bolts. However, in other variations, the fasteners 528 may be pins, welds, clips, or any other fastening or fastening method that allows the upper housing 502 and the lower housing 504 to be joined together.

[0033] The interleaved hinge 506 is operable to allow movement of a case frame (see case frame 802 in FIGS. 8-14B) of the rear visibility device 102. The interleaved hinge 506 is further operable to accommodate the openings 508 and to be comprised of a plurality of protrusions with a gap between each successive protrusion. The gap between the protrusions allows case frames 802 with corresponding protrusions to be interleaved with the interleaved hinge 506.

[0034] Opening 508 allows for insertion of tail pin 510 and is operable to axially align with an opening in an interleaved hinge of case frame 802 (as shown in FIGS. 8-14B), as described below. Opening 508 is further operable to axially align with axis 302 of FIG. 3.

[0035] Tail pin 510 is operable to be positioned through opening 508 in interleaved hinge 506. Tail pin 510 is further operable to be positioned through opening 508 and an opening in case bottom 602 or case frame 802 (shown in FIGS. 6-14B) interleaved with interleaved hinge 506. The operation and interleaving of lower portion 602 or case frame 802 with interleaved hinge 506, opening 508, and tail pin 510 will be further described below with further reference to Figures 6-14B.

[0036] The connector 512 is operable to be inserted into the actuator 402. When the connector 512 is inserted into the actuator 402, power can be supplied to the actuator 402 from the vehicle.

[0037] The camera mount 514 is operable to connect to the lower housing 504 of the actuator 402 and secure to the actuator 402 by placing a fastener 516 through the camera mount 514 and into an opening 530 .

[0038] In this variation, fastener 516 is shown as a bolt, but in other variations, fastener 516 may be a pin, a weld, a clip, or any other fastener or fastening method capable of securing camera mount 514 to actuator 402. Furthermore, in this variation, camera mount 514 is designed to secure a camera (not shown) for use with rear visibility device 102, but in other variations, camera mount 514 may be used to secure any one of a number of components used with rear visibility device 102. Non-limiting examples of components that may be attached to camera mount 514 include a multi-function lamp unit, a turn signal module, an approach lamp, or an electronic module such as a GPS module or a Wi-Fi module.

[0039] The shroud 518 is operable to be attached to the actuator 402 to seal a gap between the mirror base 204 and the mirror head 206. The shroud 518 is further operable to be attached to the actuator 402 via the lower housing 504. The shroud 518 includes one or more guides 526 that align with guides 522 on the lower housing 504. When assembled, the shapes of the guides 522 and 526 interact to align and properly position the shroud 518 on the lower housing 504. During assembly, when the shroud 518 is placed on the lower housing 504, clips 524 on the shroud 518 engage with protrusions 520 on the lower housing 504, securing the shroud 518 to the actuator 402. In this variation, the shroud 518 is secured to the lower housing 504 of the actuator 402 via the clips 524. In other variations, the shroud 518 may be secured to the actuator 402 via any other fastening method, including, but not limited to, bolts, welding, crimping, or adhesive.

[0040] The shroud 518 is further operable to have openings 536. When the shroud 518 is assembled and connected to the actuator 402, the feet 534 can fit inside the openings 536. Once the feet 534 are fitted into the openings 536 in the shroud 518, the feet 534 can be connected directly to the mirror base 204 or to the base frame 802 (shown in FIGS. 18-24B) of the mirror base 204 to secure the actuator 402 in place.

[0041] The tilt shaft 532 is operable to provide rotational movement about the axis 302 when driven by the actuator 402. The tilt shaft 532 is further operable to be secured to the case bottom 602 or case frame 802 of the rear visibility device 102. The tilt shaft 532 is further operable to include an opening 538 to which a fastener can be attached. The tilt shaft 532 is also further operable to have a shape that corresponds to a mounting element of the case bottom 602 or case frame 802. In this variation, the shape of the tilt shaft 532 is rectangular, but the tilt shaft 532 can be fitted to a corresponding mounting element. Note that tilt axis 532, opening 538, and opening 508 are axially aligned with axis 302 described in FIG.

[0042] The feet 534 are operable to provide a connection to the mirror base 204 of the rearview vision device 102. The feet 534 are further operable to connect to the mirror base 204 through openings 536 in the shroud 518.

[0043] 6 illustrates a case bottom 602 according to an embodiment of the present disclosure. As shown, the case bottom 602 further comprises an opening 604, at least one first mount 606, a second mount 608, and an additional opening 610.

[0044] The case bottom 602 is operable to provide a connection to the actuator 402 and a mounting point for the case frame 802. Although not shown in FIG. 6 , the case bottom 602 is also operable to provide, at least in part, mounting points for devices, backing plates, bezels, cameras, mirror covers, lighting modules, multi-function lamps, turn signals, lighting modules, antennas, and / or any other components that may be included in the rear visibility device.

[0045] The opening 604 is operable to provide space for the feet 534 of the actuator 402 to connect to the mirror base 204 of the rearview device 102. The opening 604 is further operable to have a shape that complements the shape of the shroud 518 of the actuator 402. The complementary shape allows the edges of the opening 604 to rotate around the shroud 518 as the case bottom 602 moves while maintaining contact between the opening 604 and the shroud 518. During movement of the case bottom 602, the continuous contact between the shroud 518 and the periphery of the opening 604 seals the gap between the actuator 402 and the case bottom 602, preventing contaminants from entering the mirror head 206.

[0046] Each first mount 606 is operable to provide an attachment point for attaching the case frame 802 to the case bottom 602 .

[0047] The second mount 608 is operable to provide an attachment point for attaching the tilt shaft 532 of the actuator 402 to the case bottom 602. The second mount 608 is further operable to have a shape such that it can receive the tilt shaft 532 of the actuator 402. The second mount 608 is further operable to include an opening 610 through which a fastener can be inserted to secure the tilt shaft 532 to the case bottom 602. The opening 610 is operable to receive the fastener and is operable to be axially aligned with the shaft 302 of FIG. 3 . As seen in FIG. 6 , the second mount 608 has the general shape of a rectangular slot. This slot corresponds to the rectangular shape of the tilt shaft 532. During assembly, the tilt shaft 532 can be rotated until aligned with the second mount 608 such that once aligned with the second mount 608, the tilt shaft 532 can be lifted and fitted into the mount 608 and secured and attached by inserting fasteners through openings 610 into openings 538 in the tilt shaft 532. Once aligned and secured, the tilt shaft 532 and case bottom 602 are rotatably locked, meaning that when the actuator 402 rotates the tilt shaft 532, the case bottom 602 rotates as well.

[0048] FIG. 7 shows the actuator 402 assembled to the case bottom 602 according to an embodiment of the present disclosure, showing the mirror base 204 and fastener 702.

[0049] During operation, the actuator 402 is lowered onto the case lower part 602 until the shroud 518 contacts the opening 604. The surface of the shroud 518 matches the surface of the opening 604, so once contact occurs, the actuator 402 rests on the case lower part 602 via the shroud 518. At this time, the tilt shaft 532 is fitted into the mount 608. As described above, the geometry of the tilt shaft 532 corresponds to the shape of the mount 608 so that the tilt shaft 532 can be fitted into the mount 608 and then secured by inserting the fastener 702 into the tilt shaft 532 through the opening 610. In this manner, as the tilt shaft 532 rotates, the case lower part 602 also rotates. In this embodiment, the fastener 702 is shown as a pin. However, in other variations, the fastener 702 may be a bolt, weld, snap, or other fastener or fastening method that allows the tilt shaft 532 to be attached to the mount 608.

[0050] At this point, the case bottom 602 is attached to the actuator 402 via fasteners 702. However, it should be apparent to one skilled in the art that problems arise from using a single connection point. Furthermore, it would be desirable to provide a means and method for attaching the remaining components used in the device. The problem of a single attachment point between the case bottom 602 and the actuator 402, as well as providing attachment means for other elements, is solved by using a case frame 802, which functions as a motor cradle by mounting the actuator 402. Such a case frame 802 for use in the device 102, 104 according to embodiments of the present disclosure will now be described with further reference to FIGS. 8-14B.

[0051] FIG. 8 shows that a case frame 802 according to an embodiment of the present disclosure includes a mount 804 , an interleaved hinge 806 , an opening 808 , and a web 810 .

[0052] Case frame 802 is operable to provide a connection to actuator 402 (not shown) via interleaved hinge 806 and opening 808, and is operable to provide a mounting point for case bottom 602 via mount 804. It should be noted that, although not shown in FIG. 8 , case frame 802 is further operable to provide, at least in part, mounting points for device, backing plates, bezels, cameras, mirror covers, lighting modules, multi-function lamps, turn signals, lighting modules, antennas, and / or any other components that may be included in the rear visibility device.

[0053] Mount 804 is operable to provide corresponding attachment points to mount 606 of case bottom 602 to facilitate attachment of case frame 802 to case bottom 602. Mount 804 may be secured to mount 606 via one of several known fastening methods, including bolts, clips, pins, welding, or any other known fastening method.

[0054] Interleaved hinge 806 of case frame 802 is operable to have a shape that is a mirror of interleaved hinge 506 of actuator 402 such that, when assembled, web 810 of interleaved hinge 806 fits between the webs of interleaved hinge 506. Interleaved hinge 806 is further operable to mate with interleaved hinge 506 such that opening 808 in case frame 802 aligns with opening 508 in actuator 402. Opening 808 is operable to be axially aligned with axis 302 of FIG. 3 .

[0055] The web 810 is operable to provide clearance between the case frame 802 and the actuator 402 during operation of the actuator 402 .

[0056] Assembly of case frame 802 will be described with further reference to Figures 9A-9B, where Figure 9A shows case frame 802 attached to a device according to an embodiment of the present disclosure.

[0057] As shown, Figure 9A includes a case frame 802 with mount 804 and opening 808, case bottom 602 with mount 606, tail pin 510 and opening 508 of upper housing 502 of actuator 402, and shaft 302. Elements common between the previous figures and Figures 9A-9B have already been described and will not be described again here for the sake of brevity.

[0058] In operation, once tilt axis 532 is secured to case bottom 602, case frame 802 may be attached. During this process, case frame 802 is lowered onto case bottom 602 so that mounts 606 and 804 are aligned, allowing the protrusions of interleaved hinges 806 to interleave with the protrusions of interleaved hinges 506.

[0059] Referring to FIG. 9B, once alignment of mount 606 and mount 804 is complete, they may be fastened together to secure case frame 802 to case bottom 602 via one of several known fastening methods, including bolts, clips, pins, welding, or any other known fastening method.

[0060] With case frame 802 securely attached to case bottom 602, opening 508 is axially aligned with opening 808, allowing for insertion of tail pin 510. Once inserted, tail pin 510 secures case frame 802 and case bottom 602 to actuator 402. Securing case frame 802 and case bottom 602 to actuator 402 provides a second attachment point for case bottom 602. Because case bottom 602 is supported on two opposing ends of a single axis, it provides significantly increased rigidity and strength. Furthermore, without a second attachment point, the outer end of case bottom 602 would be free to move or vibrate, a situation that becomes increasingly severe as additional components are attached to the device.

[0061] At this point, the feet 534 of the actuator 402 can be attached to the mirror base 204. In this embodiment, fasteners are inserted upward through the mirror base 204 and into the feet 534 to securely fasten the actuator 402. In other variations, interlocking geometries, locking rings, or other attachment methods can be used to securely attach the actuator to the mirror base. As previously mentioned, in this configuration, the surface contours of the shroud 518 and the opening 604 in the case bottom 602 create a seal that substantially prevents contaminants from entering the mirror head 206.

[0062] In this manner, rotational motion about axis 302 is transmitted from tilt axis 532 to case bottom 602 via mount 608 (FIG. 7). Simultaneously, transmission of rotational motion from tilt axis 532 about axis 302 results in rotation of case bottom 602 about axis 302 opposite tilt axis 532 of actuator 402. There are two attachment points used to connect case bottom 602 to actuator 402. The first attachment point is between tilt axis 532 and mount 608 on case bottom 602, allowing rotation of case bottom 602 about fastener 702. The second attachment point is between case frame 802 and interleaved hinge 506, via an intermediate connection made by fastening case bottom 602 to case frame 802, allowing rotation of case bottom 602 about tail pin 510. The two attachment points and their focal points of rotation, namely, tail pin 510 and fastener 702, are aligned axially with respect to axis 302 to allow for smooth rotational movement. If the focal points of rotation are not aligned with tilt axis 532 along axis 302, a misalignment will induce torque and impede movement.

[0063] It should be noted that once the case bottom 602 is effectively attached to the actuator 402, the case bottom 602 cannot fall and come into contact with the mirror base 204. Any interaction or contact between the case bottom 602 and the mirror base 204 could disrupt the function of the actuator 402 and lead to costly redesign or replacement.

[0064] Furthermore, when the case lower part 602 is attached to the actuator 402 in the manner described above, the inner periphery of the opening 604 is held against the outer surface of the shroud 518. In this configuration, when the case lower part 602 is moved by rotation of the tilt shaft 532, the edge of the opening 604 rotates around the shroud 518 without collision. This allows for smooth operation of the actuator 402 while maintaining a seal between the shroud 518 and the opening 604 to prevent the intrusion of contaminants. The tilting operation of the actuator 402 will be described further with reference to Figures 10A-10D.

[0065] FIG. 10A shows a cross section 1002 cut along the rear visibility device 102, 104, and FIGS. 10B-10D show front views along the cross section 1002 of the rear visibility device 102, 104 having the mirror head 206 in multiple nominal or tilted positions according to an embodiment of the present disclosure. Elements common between the previous figures and FIGS. 10A-10D have already been described and will not be described again here for brevity. Note that in FIGS. 10A-10D, the tail pin 510, connector 512, and camera mount 514 have been removed to provide a clearer view of the interaction between the interleaved hinge 506 of the actuator 402 and the web 810 of the interleaved hinge 806 of the case frame 802.

[0066] As shown in FIG. 10B, when the mirror head 206 is in its nominal position, there is a gap between the web 810 of the interleaved hinge 806 and the interleaved hinge 506 of the actuator 402. FIG. 10C shows a view of the mirror head 206 when tilted upward. When power is applied, the tilt axis 532 of the actuator 402 begins to rotate, causing the case bottom 602 to rotate because the case bottom 602 is rotatably fixed to the tilt axis 532. On the opposite side of the tilt axis 532 is the tail pin 510, which provides a point around which the case frame 802 can rotate. As shown in FIG. 10C, as the mirror head is tilted upward, the gap between the left side of the web 810 of the interleaved hinge 806 and the base of the interleaved hinge 506 begins to decrease. When the mirror head 206 is fully tilted upward, the angled portion of the web 810 contacts the actuator 402 at the base of the interleaved hinge 506, indicated by point 1004. The shape of the web 810 allows the angled portion of the web 810 and the base of the interleaved hinge 506 to be flush upon contact. The contact between the web 810 and the base of the interleaved hinge 506 provides a hard stop for the actuator 402, preventing the mirror head 206 from tilting upward any further.

[0067] FIG. 10D shows a view of the mirror head 206 when tilted downward. When powered, the tilt axis 532 of the actuator 402 begins to rotate in the opposite direction from that shown in FIG. 10C, causing the case bottom 602 to rotate since the case bottom 602 is rotatably fixed to the tilt axis 532. On the other side of the tilt axis 532 is the tail pin 510, which provides a point about which the case frame 802 can rotate. As shown in FIG. 10D, as the mirror head 206 tilts downward, the gap between the right side of the web 810 of the interleaved hinge 806 and the base of the interleaved hinge 506 begins to decrease. When fully tilted downward, the angled portion of the web 810 reaches the interleaved hinge 506 indicated by point 1006. The web 810 contacts the actuator 402 at the base of the interleaved hinge 506. The shape of the web 810 allows the angled portion of the web 810 to be flush with the base of the interleaved hinge 506 when they contact. The contact between the web 810 and the base of the interleaved hinge 506 provides a hard stop for the actuator 402, preventing the mirror head 206 from tilting further downward.

[0068] In this manner, tilting of the mirror head 206 can be achieved using the actuator 402 while preventing undesired contact between the case frame 802 and the actuator housings 502, 504. Additionally, the angled sides of the web 810 of the case frame 802 allow contact between the case frame 802 and the actuator 402, acting as a hard stop mechanism to prevent excessive upward or downward movement of the mirror head 206 during tilting operations. Additionally, tilting operations can be performed with a single actuator that also provides power fold operation.

[0069] In the previous variation, a two-part system including a case bottom and case frame was used with a single actuator to provide both tilt and folding movement of the rearview device, but in other variations, a spider frame can be used, as will be described with reference to Figures 11-12B.

[0070] 11 illustrates a spider frame 1102 according to an embodiment of the present disclosure, which is an alternative to the cradle-type case frame 802. As shown in FIG. 11 , the spider frame 1102 includes a mount 1104, an interleaved hinge 1106, an opening 1108, a set of webs 1110, an opening 1112, a mount 1114, and an opening 1116.

[0071] Elements common between case frame 802 and spider frame 1102 are functionally similar: mount 1104 is operable to provide an attachment mechanism to case bottom 602, interleaved hinge 1106 is operable to engage opposing interleaved hinge 506 of actuator 402, opening 1108 is operable to receive tail pin 510 as well as axially align with shaft 302, and web 1110 is operable to provide clearance between spider frame 1102 and the base of interleaved hinge 506 of actuator 402. Opening 1112 is operable to provide an opening so that tail pin 510 may be inserted into opening 1108.

[0072] The spider frame 1102 further includes several elements attached to the case bottom 602 in the previous variation, namely, a mount 1114 and an opening 1116. The mount 1114 and the opening 1116 are functionally similar to the corresponding elements of the case bottom 602. As can be seen in FIG. 11 , the mount 1114 has the general shape of a rectangular slot. The rectangular slot shape corresponds to the rectangular shape of the tilt shaft 532. During assembly, the tilt shaft 532 can be rotated until aligned with the mount 1114 such that, once aligned with the mount 1114, the tilt shaft 532 can be lifted and fitted into the mount 1114, and then secured and attached by inserting the fasteners 702 through the openings 1116 and into the openings 538 of the tilt shaft 532. Once aligned and secured, the tilt shaft 532 and spider frame 1102 are rotationally locked, meaning that when the actuator 402 rotates the tilt shaft 532, the spider frame 1102 rotates as well.

[0073] The assembly of the spider frame 1102 will now be described with further reference to Figures 12A-12B.

[0074] 12A shows a spider frame 1102 attached to a rearview mirror assembly according to an embodiment of the present disclosure. Mount 1202 on case bottom 602 is operable to provide a corresponding attachment point for mount 1104 on spider frame 1102. The difference between mount 1202 and mount 606 shown in FIG. 6 is that the shape of mount 1202 has been modified to allow it to attach to mount 1104 on spider frame 1102.

[0075] FIG. 12B shows the spider frame 1102 attached to the rearview vision device according to an embodiment of the present disclosure. Once the spider frame 1102 is attached to the actuator 402 and the case bottom 602, the system can operate as previously described in FIGS. 10A-10D . Briefly, on a first side, the tilt axis 532 is inserted into the mount 1114 of the spider frame 1102 and then held in place by insertion of the fastener 702. On the side of the actuator 402 opposite the tilt axis 532, the tail pin 510 can be inserted into the opening 508 of the interleaved hinge 506 and the opening 1108 of the interleaved hinge 1106. The mount 1104 of the spider frame 1102 can then be secured to the mount 1202 of the case bottom 602.

[0076] Once the spider frame 1102 is installed, the actuator 402 can be operated to impart movement to the mirror head 206. When power is applied to the actuator 402, it can begin to rotate the tilt axis 532. The fasteners 702 and tail pins 510 used to attach the spider frame 1102 to the actuator 402 are axially aligned along the axis 302 so that the rotational movement of the tilt axis 532 can be transmitted through the spider frame 1102 and the lower case 602 to the mirror head 206 such that the mirror head 206 rotates about the axis 302. The geometry of the interleaved hinges 506, 1106 of the actuator 402 and spider frame 1102 allows movement of the spider frame 1102 and the lower case 602 without interference. When tilted upward or downward to the maximum design angle, the surface of one of the sloped sides of the web 1110 of the spider frame hinge 1106 contacts the base portion of the actuator interleaved hinge 506 to prevent the mirror head 206 from tilting further.

[0077] In the previous embodiment, a two-part system comprising a case bottom and case frame or spider frame was used with a single actuator to provide both tilt and folding operation of the rearview device. However, in other variations, a bezel-mounted case frame 1302 can be used, as described with reference to Figures 13-14B.

[0078] FIG. 13 shows a bezel-mounted case frame 1302 according to an embodiment of the present disclosure, which includes a mount 1304, an interleaved hinge 1306, an opening 1308, a set of webs 1310, an opening 1312, a mount 1314, an opening 1316, and a mount 1318.

[0079] The elements common to case frame 802 and bezel-mounted case frame 1302 are functionally similar. Mount 1304 is operable to provide an attachment mechanism to case bottom 602, interleaved hinge 1306 is operable to engage with opposing interleaved hinge 506 of actuator 402, opening 1308 is operable to receive tail pin 510 as well as axially align with axis 302, and web 1310 is operable to provide clearance between bezel-mounted case frame 1302 and the base of interleaved hinge 506 of actuator 402. Opening 1312 is operable to allow tail pin 510 to be inserted into opening 1308. The opening is operable to provide an opening for the

[0080] The bezel-mounted case frame 1302 further includes several elements that were attached to the case bottom 602 in the previous variation: a mount 1314 and an opening 1316. The mount 1314 and opening 1316 are functionally similar to the corresponding elements of the case bottom 602. As can be seen in FIG. 13 , the mount 1314 has the general shape of a rectangular slot. The rectangular slot shape corresponds to the rectangular shape of the tilt shaft 532. During assembly, the tilt shaft 532 can be rotated until aligned with the mount 1314 such that, once aligned with the mount 1314, the tilt shaft 532 can be lifted and fitted into the mount 1314, and then securely attached by inserting the fastener 702 through the opening 1316 and into the opening 538 in the tilt shaft 532. Once aligned and secured, the tilt shaft 532 and the bezel-mounted case frame 1302 are rotatably locked, meaning that when the actuator 402 rotates the tilt shaft 532, the bezel-mounted case frame 1302 rotates as well.

[0081] 14A-14B, the assembly of the bezel mounted case frame 1302 will now be described.

[0082] 14A shows a bezel-mounted case frame 1302 attached to a rearview viewing device according to an embodiment of the present disclosure. Shown are mount 1304, interleaved hinge 1306, mount 1314, opening 1316, mount 1318, fastener 702, case bottom 602, tilting axis 532, actuator 402, and axis 302, as well as mount 1402, bezel-like backing plate assembly 1404, and mount 1406. Elements common between the previous figures and FIGS. 14A-14B have already been described and will not be described again here for the sake of brevity.

[0083] Mount 1402 on case bottom 602 is operable to provide a corresponding attachment point for mount 1304 on bezel-mounted case frame 1302. The difference between mount 1402 and mount 606 shown in FIG. 6 is that mount 1402 has been modified to attach to mount 1304 on bezel-mounted case frame 1302.

[0084] The backing plate assembly 1404 is operable to provide or support a means for reflecting visibility from the rear of the vehicle 100 toward the driver of the vehicle 100. In this variation, the backing plate assembly 1404 is provided as a complete assembly, while in other variations, the backing plate assembly 1404 may be provided as a frame or mounting portion to which glass or reflective elements are later attached. The backing plate assembly 1404 is further operable to include a mount 1406 that allows for attachment to the mount 1318 of the bezel-mounted case frame 1302.

[0085] FIG. 14B illustrates a bezel-mounted case frame 1302 attached to a rearview vision device according to an embodiment of the present disclosure. Once the bezel-mounted case frame 1302 is attached to the actuator 402 and the case bottom 602 as shown in FIG. 14B , the system can operate as previously described with reference to FIGS. 10A-10D . Briefly, the tilt axis 532 is inserted into the mount 1314 of the bezel-mounted case frame 1302 and then held in place by the insertion of the fastener 702. On the side of the actuator 402 opposite the tilt axis 532, the tail pin 510 can be inserted into the opening 508 of the interleaved hinge 506 and the opening 1308 of the interleaved hinge 1306. The mount 1304 of the bezel-mounted case frame 1302 can then be secured to the mount 1402 of the case bottom 602. The backing plate assembly 1404 can then be attached to the bezel-mounted case frame 1302 by fastening the mount 1406 to the mount 1318. do.

[0086] Once the bezel-mounted case frame 1302 is attached, the actuator is operational. When power is applied to the actuator 402, it can begin to rotate the tilt axis. The fasteners 702 and tail pins 510 used to attach the bezel-mounted case frame 1302 to the actuator 402 are axially aligned along axis 302, so that rotational motion of the tilt axis 532 can be transmitted through the bezel-mounted case frame 1302 and case bottom 602 to the entire mirror head 206 for rotation about axis 302. The geometry of the interleaved hinges 506, 1306 on both the actuator 402 and the bezel-mounted case frame 1302 allows the bezel-mounted case frame 1302 and case bottom 602 to move without interference. When tilted upward or downward to the maximum design angle, the surface of one of the sloped sides of the bezel web 1310 attached to the case frame 1302 contacts the base portion of the actuator interleaved hinge 506 to prevent the mirror head from tilting further.

[0087] In a further embodiment, the rearview mirror adjustment actuator may be provided with a gasket to seal the gap between the shroud 518 and the lower case portion 602, as described with reference to Figures 15-24B.

[0088] FIG. 15 illustrates a case bottom 1502 and a gasket 1504 according to an embodiment of the present disclosure. As shown, the case bottom 1502 includes an opening 1506, a guide 1508, at least one recess 1510, and an attachment point 1512. The gasket 1504 includes at least one protrusion 1514 and a seal 1516. The opening 1506 is operable to provide an opening through which a mirror base (not shown) can be connected to an actuator (not shown). Each attachment point 1512 is operable to provide a point through which a case frame (not shown) can be attached to the case bottom 1502. The guide 1508 is provided on the case bottom 1502 with a curvature that matches the curvature of the gasket 1504. The gasket 1504 can be installed on the case bottom 1502 when the at least one protrusion 1514 of the gasket 1504 is aligned with the at least one recess 1510 of the guide 1508. Insertion of the guide 1508 and at least one protrusion 1514 into the at least one recess 1510 secures the gasket 1504 in place relative to the case bottom 1502 .

[0089] While the gasket 1504 and the seal 1516 are described as separate elements, in this embodiment they are combined as a single element. During manufacturing, the gasket 1504 and the seal 1516 can be fabricated as a single element using a dual-injection molding technique (2K or two-shot molding). 2K molding is a manufacturing process in which a complex part is molded using two different materials in a single molding machine. In this embodiment, the gasket 1504 is molded from a PP-GF material; however, in other variations, the gasket 1504 can be molded from ASA, ABS, PMMA, or any other material that can be molded as part of a 2K process. Additionally, in this embodiment, the seal 1516 is molded from a TPE material; however, in other variations, the seal 1516 can be molded from silicone, PVC, or any other material that can be molded as part of a 2K process.

[0090] 16 shows a bottom view of an actuator 1602 and a shroud 1604 according to an embodiment of the present disclosure. The actuator 1602 includes an extension 1606 and at least one opening 1608, which in this embodiment includes three openings. The shroud 1604 includes a first protrusion 1610A and a second protrusion 1610B. The extension 1606 is operable to be received within a correspondingly shaped recess in a base frame (not shown). The matching geometries allow the actuator 1602 to be mounted within the base frame. 2 and the mirror base. At least one opening 1608 is operable to receive a fastener (not shown) to secure the actuator 1602 to the base frame of the rearview device. The shroud 1604 is attached to the actuator 1602 as described above in FIGS. 5A-5B and will not be described again here for brevity. The protrusions 1610A, 1610B extend through openings 1506 in the case bottom 1502 of FIG. 15 when the actuator 1602 is positioned thereon.

[0091] In this embodiment, the shroud 1604 is molded from a PBT-GF material, although in other variations, the shroud 1604 may be molded from ASA, ABS, PMMA, or any other material that can be molded.

[0092] FIG. 17A shows a top view and FIG. 17B shows a bottom view of an actuator 1602 secured to a case bottom 1502 according to an embodiment of the present disclosure. As shown in FIG. 17A, a case frame 1702 has a first attachment element, which in this variation is attachment point 1704, and a second attachment element, which in this variation is attachment point 1706. The case frame 1702 is attached to the actuator 1602 via attachment points 1704, 1706, with the first attachment point 1704 attached to the actuator tilt axis 532 as described with respect to FIG. 5, and the attachment point 1706 attached to the interleaved hinge 506 as described with respect to FIG. 5. The case frame 1702 is attached to the actuator 1602 via the first attachment point 1704 and the second attachment point 1706 as described above with respect to FIGS. 5-14B, and for the sake of brevity, the details of these methods will not be described again here.

[0093] Next, the actuator 1602 is placed on the case bottom 1502 so that the shroud 1604 abuts the seal 1516 of the gasket 1504. Once the shroud 1604 abuts the seal 1516 (not shown), the case frame 1702 can be attached to the case bottom 1502 via attachment points 1708. Because the case frame 1702 is attached to the actuator 1602, when the case frame 1702 is further secured to the case bottom 1502, the actuator 1602 is also coupled to the case bottom 1502, keeping the shroud 1604 abutting the seal 1516 of the gasket 1504. The abutment between the shroud 1604 and the seal 1516 seals and prevents the ingress of contaminants, such as water, dust, salt, or other fluids or debris, into the mirror head.

[0094] 17B, ​​it can be seen that when the actuator 1602 is attached to the case bottom 1502, the first and second protrusions 1610A, 1610B extend through the opening 1506 in the case bottom 1502. Additionally, the extension 1606 and at least one opening 1608 of the shroud 1604 are accessible through the opening 1506 in the case bottom 1502 for attachment to a mirror base (not shown).

[0095] 2-14B, the actuator 1602 is operable to rotate the lower case portion 1502 along two separate axes, again axis 202 and axis 302 in this embodiment. During rotation about axis 202, both the shroud 1604 and the lower case portion 1502 rotate simultaneously with the actuator 1602. During rotation about axis 202, there is no relative motion between the shroud 1604 and the lower case portion 1502 or between the shroud 1604 and the seal 1516 and gasket 1504.

[0096] While the case bottom 1502 rotates about the axis 302, the shroud 1604 remains stationary as it is fixedly attached to the actuator 1602. As the case lower 1502 rotates, the gasket 1504 also rotates, causing the seal 1516 to move across the surface of the shroud 1604. Because the seal 1516 and the shroud 1604 abut, the materials selected for the seal 1516 and the shroud 1604 affect the ability of the actuator 1602 to rotate the case lower 1502 about the axis 302. The materials for the shroud 1604 and the seal 1516 can be selected to increase or decrease the ability of the actuator 1602 to rotate the case lower 1502 about the axis 302.

[0097] Additionally, manufacturer or customer requirements for the surface of the shroud 1604 may result in the use of materials that are not suitable for the actuator 1602. By separating the shroud 1604 from the actuator 1602, these surface requirements can be met without interfering with the integrity or functionality of the actuator 1602.

[0098] The attachment of the actuator 1602 to the mirror base will be described with reference to FIGS.

[0099] FIG. 18 illustrates a mirror base having a base frame 1802 according to an embodiment of the present disclosure. As shown, the base frame 1802 includes one or more recesses 1804, at least one opening 1806, and a protrusion 1808. Each recess 1804 has a contour that matches the contour of the extension 1606 of the actuator 1602 such that the matching contours facilitate alignment of the at least one opening 1806 when the actuator 1602 is placed on the base frame 1802. In this embodiment, the at least one opening 1806 includes three openings in the base frame 1802 that match the openings 1608 in the actuator 1602. The alignment between the openings 1806, 1608 allows for the insertion of fasteners to securely attach the actuator 1602 to the base frame 1802. In this embodiment, the fasteners used to securely attach the actuator 1602 to the base frame 1802 are bolts (not shown). However, in other variations, the fasteners used may be pins, welds, clips, or any other fastener or fastening method capable of fixedly attaching the actuator 1602 to the base frame 1802. An opening 1810 is provided on the base frame 1802 as an attachment point for a breakface gasket (not shown).

[0100] FIG. 19 illustrates a front view of the actuator 1602 mounted to a base frame 1802 in a nominal position according to an embodiment of the present disclosure. As shown in FIG. 19 , the base frame 1802 is provided with a breakface gasket 1902. The breakface gasket 1902 includes fasteners 1904, which in this variation are clips, that are inserted into openings 1810 in the base frame 1802. The fasteners 1904 inserted into the openings 1810 securely fasten the breakface gasket 1902 to the base frame 1802. When the actuator 1602 is mounted to the base frame 1802, the breakface gasket 1902 abuts against the shroud 1604 to seal the gap between the base frame 1802 and the actuator 1602. Furthermore, the case frame 1702 is coupled to the actuator 1602 and the case bottom 1502 such that the shroud 1604 abuts against the seal 1516 of the gasket 1504. Additionally, the actuator 1602 is attached to the base frame 1802 by first aligning the extension 1606 of the actuator 1602 with the recess 1804 in the base frame 1802. Once aligned, a fastener (not shown) is inserted through the at least one opening 1806 and into the at least one opening 1608 to securely attach the actuator 1602 to the base frame 1802.

[0101] Actuator 1602 is used to move gasket 1504 and breakface gasket The inclusion of the breakface gasket 1902 in the rearview device improves the vibration frequency of the rearview device. Without the gasket 1504 or the breakface gasket 1902, the only support between the base frame 1802 and the actuator 1602 is between the extension 1606 of the actuator 1602 and the recess 1804 in the base frame 1802. A fastener is further inserted through the at least one opening 1806 in the base frame 1802 and into the at least one opening 1608 in the actuator 1602 to secure the actuator 1602 to the base frame 1802. The arrangement of the extension 1606 and the recess 1804, and the insertion of the fastener into the at least one opening 1608 and the at least one opening 1806, primarily provides support along axis 202 but little structural support along axis 302.

[0102] The abutment between the shroud 1604 and the breakface gasket 1902 and the abutment between the shroud 1604 and the seal 1516 of the gasket 1504 provides additional support along axis 202 and axis 302. This additional support along axis 302 reduces the vibration amplitude of the case bottom 1502 and any other elements attached to the case bottom 1502, which in this embodiment includes a mirror reflective element (not shown).

[0103] FIG. 20 shows the assembly of FIG. 19 with the breakface gasket 1902 removed for clarity. When the actuator 1602 is fixedly attached to the base frame 1802, the protrusions 1610A and 1610B (not shown) of the shroud 1604 extend through the case bottom 1502 toward the base frame 1802 until they are flush with the protrusion 1808. When the protrusions 1610A, 1610B, and 1808 are flush with each other, they can interact to prevent the mirror head from continuing to move during impact rotation. Further description of the protrusions 1610A, 1610B, and the protrusion 1808, which acts as a hard stop to prevent rotation during a crash, is provided with further reference to FIGS. 21A-22B.

[0104] 21A shows a front view of the shroud 1604 aft against a hard stop, according to an embodiment of the present disclosure. FIG. 21B shows a side view of the shroud aft against a hard stop, according to an embodiment of the present disclosure. For clarity, the break face gasket 1902 has been removed from FIGS. 21A-21B.

[0105] As shown in FIGS. 21A-21B, when a force is applied to a portion of the mirror head, represented in this example by the lower case part 1502, the applied force causes the entire mirror head to rotate. In this embodiment, a force applied to the lower case part 1502 rotates the mirror head toward the rear of the equipped vehicle. The actuator 1602, shroud 1604, and case frame 1702 are fixedly attached to the lower case part 1502 and therefore rotate as the lower case part 1502 rotates. The lower case part 1502 continues to rotate until the protrusion 1610A of the shroud 1604 abuts the protrusion 1808 of the base frame 1802. The abutment between the protrusion 1610A and the protrusion 1808 acts as a hard stop, preventing further rotation of the lower case part 1502.

[0106] FIG. 22A shows a front view of the shroud 1604 hitting a hard stop at the front, according to an embodiment of the present disclosure. FIG. 22B shows a side view of the shroud 1604 hitting a hard stop at the front, according to an embodiment of the present disclosure. For clarity, the break face gasket 1902 has been removed from FIGS. 22A-22B. Similar to FIGS. 21A-21B above, when a force is applied to a portion of the mirror head, the applied force causes the entire mirror head to rotate. In this embodiment, a force applied to the case bottom 1502 rotates the mirror head toward the front of the equipped vehicle. The actuator 1602, shroud 1604, and case frame 1702 are fixedly attached to the case bottom 1502. As the case bottom 1502 rotates, it will rotate until protrusion 1610B of shroud 1604 abuts protrusion 1808 of base frame 1802. The abutment between protrusion 1610B and protrusion 1808 acts as a hard stop, preventing further rotation of the case bottom 1502.

[0107] The operation of the actuator 1602, which moves the mirror head along two different axes, is identical to the operation of the actuator 402 described above with respect to FIGS. 2A-14B. The actuator 1602 is operable to adjust the mirror head along two separate axes to perform both tilt and folding functions. In this embodiment, the actuator 1602 performs the folding function about axis 202 and the tilt function about axis 302. The protrusion 1808 is disposed on the base frame 1802 and is fixed in position relative to axes 202 and 302, while the protrusions 1610A and 1610B of the shroud 1604 are fixed only along axis 302. Thus, when the actuator 1602 begins to rotate, the shroud protrusions 1610A and 1610B rotate as well. The actuator 1602 continues to rotate until flush contact is made between the protrusion 1610A or 1610B and the protrusion 1808.

[0108] If the protrusions 1610A and 1610B are not fixed along the axis 302, the protrusions 1610A or 1610B can rotate along the axis 302 to make flush contact with the protrusion 1808 during rotation about the axis 302. As an example, if the protrusion 1610A is moved from the shroud 1604 and positioned on the case lower 1502 so that it can make contact with the protrusion 1808, when the case lower rotates about the axis 302, the protrusions 1610A and 1808 will not make flush contact as the case lower 1502 rotates about the axis 202. Non-flush contact between the protrusions 1610A and 1808 can result in damage to either component, such as increased wear or a shortened lifespan, and the lack of a hard stop function can lead to damage to other components of the rearview vision device.

[0109] As described in FIGS. 21A-22B, protrusions 1610A and 1610B are positioned on shroud 1604 to function as hard stops in a first direction or a second direction. In this embodiment, the first direction is toward the rear of the vehicle, and the second direction is toward the front of the vehicle. Furthermore, in this embodiment, protrusions 1610A and 1610B are positioned on shroud 1604 to contact protrusion 1808 after 70 degrees of rotation. After 70 degrees of rotation rearward or forward from the nominal position, protrusions 1610A or 1610B contact protrusion 1808 to prevent further rotation. However, different manufacturers and customers may require different rotation angles. Additionally, in this embodiment, different shrouds can be attached to actuators with protrusions 1610A and 1610B positioned at different positions, such that protrusion 1610A contacts protrusion 1808 after 80 degrees of rearward rotation and protrusion 1610B contacts protrusion 1808 after 60 degrees of forward rotation. Shrouds can be manufactured with protrusions 1610A and 1610B positioned to act as hard stops after any angle a customer may require. In this way, a single actuator can be used for all rear sight devices to provide rear sight devices with different maximum rotation angles simply by changing the shroud.

[0110] 23 shows a base cover of a rear visibility device according to an embodiment of the present disclosure having an upper base cover 2302 and a lower base cover 2304 attached to a base frame 1802. When attached to the base frame 1802, the upper edges of the upper base cover 2302 and the lower base cover 2304 abut against the breakface gasket 1902, creating a seal that prevents particles or contaminants from entering the rear visibility device through a gap between the breakface gasket 1902 and the base frame 1802.

[0111] In the above-described embodiment, the shroud was provided for use with an actuator that was fixedly attached to the actuator. In this configuration, the shroud moves with the actuator, but in other variations, a shroud may be provided that is static and not attached to an actuator. Static shroud 2402 will now be described with reference to Figures 24A / 24B.

[0112] FIG. 24A illustrates a stationary shroud 2402 for a rearview vision device according to an embodiment of the present disclosure. As shown in FIG. 24A , a base frame 1802 is provided with the shroud 2402. The shroud 2402 is clamped between the base frame 1802 and a shaft 2410 of an actuator 2408, as indicated by point 2404. Once clamped between the base frame 1802 and the shaft 2410, fasteners 2412 can be inserted through the base frame 1802 and onto the shaft 2410 to secure the shroud 2402 and shaft 2410 to the base frame 1802. With the shroud 2402 secured in place, a seal is created between the shroud 2402 and the base cover 2414, and between the shroud 2402 and the mirror head 2406, preventing the ingress of contaminants, such as water, dust, salt, or other fluids or debris, into the mirror head 2406.

[0113] 1-14B , the actuator 2408 can rotate the mirror head 2406 about axis 202 or axis 302. During rotation about axis 202, the mirror head 2406 rotates relative to the shroud 2402. As the mirror head 2406 rotates about axis 202 and the shroud 2402 remains stationary, the mirror head 2406 contacts the shroud 2402 at contact points 2416 around the periphery of the shroud 2402.

[0114] FIG. 24B illustrates the rotation of the mirror head 2406 about the stationary shroud 2402, according to an embodiment of the present disclosure. During operation, the actuator 2408 may be required to rotate the mirror head 2406 about the axis 302, as described above with respect to FIGS. 1-14B. The operation of the mirror head 2406 rotating about the axis 302 is the same whether a static shroud or an actuator-mounted shroud is used. As the mirror head 2406 rotates about the axis 302, the lower case 602, 1502 of the mirror head 2406 traverses upward on one side of the shroud 2402 and downward on the other side of the shroud 2402. During rotation about the axis 302, the mirror head 2406 remains in contact with the shroud 2402, as indicated by the contact points 2416 around its periphery.

[0115] 25A and 25B show an alternative hinge 3506 provided by the upper housing 3502 of the actuator 3408, with its shaft 3410 also shown. The hinge 3506 includes two recesses 3503, 3504 on either side of a protrusion 3505 and is disposed between two walls of the upper housing 3502, with the walls and protrusion 3505 acting as the web mentioned above. However, to facilitate the introduction of a tail pin 3510, the upper housing 3502 provides a single opening 3508 for inserting the tail pin 3510, such that the inclined bearing surface 3511 of the tail pin 3510 is supported by the protrusion 3505, while the threaded region 3512 of the tail pin 3510 is adapted to be threaded into another opening 3509 in the upper housing 3502, which is provided with an internal thread. This configuration not only facilitates insertion of the tail pin 3510, but also provides sufficient strength of the connection by utilizing the threaded region 3512.

[0116] 26A and 26B show an alternative to FIGS. 25A and 25B. In particular, a two-walled upper housing 4502 can be seen, with an opening 4508 in the first wall and an opening 4509 in the second wall that is internally threaded. The two walls of the upper housing 4502 are positioned to leave a recess 4503 therebetween. A tail pin 4510 is provided at the incline. The beveled bearing surface 4511 is adapted to be inserted into the opening 4508 and the threaded region 4511 is adapted to be inserted into the opening 4509. The hinge 4506 with the two walls and the recess 4508 functions as the hinge with the web discussed above.

[0117] The two alternative structures of the hinges 3506, 4506 formed with the upper housing 3502, 4502 of the actuator 3408 discussed with respect to Figures 25A-26B interact with complementary hinges provided by the case frame (not shown) in a similar manner as described for the embodiment shown in Figures 5A-24B, with the number of interleaved hinge leaves more or less reduced for assembly process advantages. Thus, each hinge 3506, 4506 still functions as an interleaved hinge that allows tilt while providing a hard stop, as described in detail with respect to Figures 10A-10D. The number of hinge leaves can vary, as the range of tilt is controlled by the recess between adjacent leaves and the extension of the leaves. For example, Figure 5A shows three lobes of hinge 506 whose extensions decrease towards the edge of upper actuator housing 502 where they join the tilting surface, with three slot-like recesses formed between said three lobes, and for example, Figure 26A shows one lobe of hinge 4506 providing one recess 4503 sufficient to fulfill the functions outlined in controlling the tilt range. The selection of the number of lobes and the distance between adjacent lobes, which determines the height of the recesses and lobes, depends on the required tilt range.

[0118] 27 shows another tilt shaft 5320 having a central opening 5380 for inserting a fastener (not shown), as described with respect to the above embodiment. The difference between the tilt shaft 5320 shown in FIG. 5B and the tilt shaft 532 is the shape, particularly its cross section. The tilt shaft 5320 is substantially T-shaped with a tapered portion 5321 and a rounded portion 5322. This shape ensures a secure attachment and easy insertion into a respective mount provided by the case bottom (not shown) or case frame (not shown). Said mount may be in the form of a slot having a shape complementary to that of the tilt shaft 5320.

[0119] The rearview device 102 and the rearview device 104 may include optional elements not shown. The optional elements may include a camera module, an indicator module, a light module, a blind side detection module, a blind side indicator, a multi-function light module, an exterior light module, an interior light module, a front light, a back light, a fog light, a brake light, an accelerator light, a turn signal, a logo lamp, a front area illumination light, a ground illumination light, a puddle light, a flashing light, a navigation light, a position light, an emergency light, a spot light, a green light, a red light, a warning light, a turn signal light module, an approach light, a search light, an information light, a display, an antenna, and / or any combination thereof. Some of the optional elements may also be integrated to function behind or through a coating, such as a partially transparent chrome-based coating. Examples of partially transparent chromium-based coatings for polymer substrates are described in U.S. patent application Ser. No. 14 / 936,024, filed Nov. 9, 2015, for COATED POLYMERIC SUBSTRATES, and U.S. patent application Ser. No. 15 / 124,310, filed Feb. 20, 2015, for DECORATIVE COATINGS FOR PLASTIC SUBSTRATES, all of which are incorporated herein by reference.

[0120] Some of the desired elements may provide an indicator signal to the driver of a vehicle equipped with one of the rear visibility devices 102 or 104. An example of providing an indicator signal to the driver is described in "AUTOMOBILE EXTERIOR VEHICLE SYSTEM 100" filed on July 25, 2019. REAR VIEW MIRROR BLIND SPOT WARNING IND No. 16 / 522,074, filed Jan. 19, 2016, for a "LIGHT GUIDING DEVICE," and U.S. patent application Ser. No. 15 / 000,733, filed Jan. 19, 2016, for a "LIGHT GUIDING DEVICE," all of which are incorporated herein by reference.

[0121] In summary, conventional rearview devices operate components along multiple axes. To enable actuation along multiple axes, a second actuator is used, which increases the complexity and cost of the engineering and assembly.

[0122] Aspects of the present disclosure provide a system for creating a seal between an actuator and a mirror head using a gasket, a seal, and a shroud. The seal prevents contaminants such as water, dust, salt, or other fluids or debris from entering the mirror head. Attaching the mirror head to a mirror base with a gasket creates another seal between the mirror base and the shroud, preventing contaminants such as water, dust, salt, or other fluids or debris from entering the mirror head.

[0123] The foregoing description of various variations has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teachings. The variations have been chosen and described in order to best explain the principles of the disclosure and its practical application, so as to enable others skilled in the art to optimally utilize the disclosure in its various variations and modifications for the particular uses contemplated.
