Abstract

An interior rearview mirror for vehicles has a housing having an interior. A mirror support has a first end and a second end, wherein the housing is connected to the first end of the mirror support and wherein the first end projects into the interior of the housing. A mirror pane is mounted in an opening of the housing. A switching member is mounted in the interior of the housing and is pivotable on the first end of the mirror support. An adjusting lever is mounted in the housing and projects from the housing. At least one spring is configured to act on the adjusting lever. The adjusting lever is movable against a force of the at least one spring and acts on the switching member for pivoting the mirror pane from a normal viewing position into a non-glare position. The switching member receives the force of the at least one spring exerted onto the adjusting lever and thus prevents deformation of the housing.

5. The interior rearview mirror according to claim 3, wherein said switching member (5) has wall portions (50, 51) with ends (53, 54) projecting past an end face of said switching member (5) and wherein said ends (53, 54) form said link bracket (63, 64).

6. The interior rearview mirror according to claim 5, wherein said ends of said wall portions (53, 54) have an inwardly projecting edge (61, 62) and wherein said at least one bearing pin (65, 66) rests against said inwardly projecting edge (61, 62).

7. The interior rearview mirror according to claim 1, wherein said switching member (5) has a recess and wherein said at least one spring (8) is arranged in said recess (42).

8. The interior rearview mirror according to claim 7, wherein said switching member (5) comprises an upper element and a lower element and wherein said recess is located between said upper and said lower elements (54, 55).

9. The interior rearview mirror according to claim 1, wherein said first end of said mirror support (4) has a spherical head (6) and wherein said switching member (5) is seated on said spherical head (6).

10. The interior rearview mirror according to claim 9, wherein said switching member (5) has a projecting annular collar (28) having several slots (28′

) arranged successively and spaced apart in a circumferential direction of said annular collar (28).

11. The interior rearview mirror according to claim 1, wherein said switching member (5) has laterally projecting pins (9, 10) configured to support said switching member (5) in said housing (2).

12. The interior rearview mirror according to claim 11, wherein said housing (2) has bearing openings (26, 27) and wherein said laterally projecting pins (9, 10) are positioned in said bearing openings (26, 27).

13. The interior rearview mirror according to claim 12, wherein said housing (2) has an inner wall with projecting transverse stays (17, 18), wherein said transverse stays (17, 18) have first widened ends (20, 22), and wherein said bearing openings (26, 27) are located in said first widened ends (20, 22).

14. The interior rearview mirror according to claim 13, wherein said widened ends (20, 22) are double-walled.

15. The interior rearview mirror according to claim 13, wherein said housing (2) has longitudinal walls (14, 15), wherein said transverse stays (17, 18) extend between said longitudinal walls (14, 15) and laterally adjacent to said switching member (5).

16. The interior rearview mirror according to claim 15, wherein said transverse stays (17, 18) have second widened ends (19, 20) adjacent to said adjusting lever (7).

17. The interior rearview mirror according to claim 16, wherein said first and second widened ends (19, 20, 21, 22), adjoining said longitudinal walls (14, 15), respectively, extend substantially over an entire height of said longitudinal walls (14, 15).
