With a pivot element of the toggle mechanism attached at the mirror mount, and when the toggle lever pivots relative to the lower receiving portion of the mirror casing, the mirror casing pivots relative to the body portion to flip the mirror head between a first orientation and a second orientation.

Provided is a base (1) for a flexible mold that is to be wound in an endless manner, and the base includes: an intermediate sheet (2); and first and second resin sheets (3, 5) bonded to both main surfaces of the intermediate sheet (2) through intermediation of first and second bonding layers (4, 6), respectively. The intermediate sheet (2) includes: first and second spacer sheets (7, 8), which are each made of a resin, and are arranged at one end portion and another end portion in a winding direction, respectively; and a glass sheet (9) arranged between those spacer sheets (7, 8).

A method of making a rearview assembly includes operably coupling a rearview device with a front housing. A bonding material is applied to the front housing and a printed circuit board is operably coupled with the front housing. A rear housing is engaged with the front housing. Energy is applied to bond the front housing with the rear housing.

Methods of forming a mirror by bonding a faceplate to a core structure using adhesive formulations that include: (1) a binder comprising 40 to 60 weight % monoaluminum phosphate and 40 to 60 weight % water, the binder constituting 25 to 35 weight % of the adhesive formulation and, (2) a composition that includes a first set of particles having a coefficient of thermal expansion equal to or less than 0.05 ppm/° C. and diameters between 1 to 60 micrometers and a second set of particles having a coefficient of thermal expansion equal to or less than 0.05 ppm/° C. and diameters between 0.05 to 1 micrometers, the first set of particles constituting 80 to 85 weight % of the composition, the second set of particles constituting 15 to 20 weight % of the composition; the composition constituting 65 to 75 weigh % of the adhesive formulation.

A three-dimensional printing device including a rigid optically transparent plate, a release film, an adhesive layer, a light source, and a reflection assembly is provided. The rigid optically transparent plate has a first surface and a second surface opposite the first surface, the release film is disposed on a side of the rigid optically transparent plate adjacent to the first surface, and the adhesive layer is arranged between the rigid optically transparent plate and the release film. The light source is disposed on a side of the rigid optically transparent plate adjacent to the second surface, and the reflection assembly includes at least one mirror and is arranged at a position capable of forming a light path from the light source to the rigid optically transparent plate.

A vehicular trailer hitching assist system includes a rear backup camera disposed at a rear portion of a vehicle and a control disposed in the vehicle. A display device includes a video display screen operable to display video images for viewing by a driver of the vehicle. Responsive to the driver initiating a hitching maneuver event by engaging reverse gear of the vehicle, rear backup video images derived from image data captured by the rear backup camera are displayed at the video display screen. An overlay overlays the displayed rear backup video images and aids in guiding connection of a trailer hitch of the equipped vehicle to a trailer tongue of a trailer. Continued display of rear backup video images that are overlaid by the overlay is ceased upon elapse of a threshold period of time or upon exceeding a threshold speed or upon exceeding a threshold distance traveled.

Methods of forming a mirror by bonding a faceplate to a core structure using adhesive formulations that include fused silica particles having diameters that range between 1 to 60 micrometers with an average diameter of the silica particles being between 8 to 10 micrometers. The adhesive formulation further includes an activator including 25 to 50 weight % sodium silicate, 25 to 50 weight % sodium hydroxide and a liquid. The fused silica particles constitute 70 to 80 weight % of the adhesive formulation and the activator constitute 20 to 30 weight % of the adhesive formulation.
