  • Rearview mirror device with wide viewing angle
    Patent number: 7717577
    Abstract: A rearview mirror device includes an elongated mirror body and a housing. The mirror body is formed with a first curved section having two opposite ends, and second and third curved sections extending integrally and respectively from the opposite ends of the first curved section. The first curved section has a radius of curvature larger than a radius of curvature of the second curved section and a radius of curvature of the third curved section. A ratio of the radius of curvature of the first curved section to the radius of curvature of either one of the second and third curved sections is not greater than 1.65. The housing includes a frame body with first and second mounting portions. Each of the second and third curved sections is mounted on a respective one of the first and second mounting portions of the frame body.
