## Abstract

A mirror assembly may comprise a housing; a support bracket rotatably disposed on the housing and coupled to a mirror; and a tilting module mounted on the support bracket and tilting or untilting the support bracket relative to the housing. The tilting module may comprise a slider slidably mounted on the support bracket; a main spring disposed between the housing and the slider; a button cover mounted on the support bracket; a cover body coupled with the button cover; a button disposed between the button cover and the cover body so as to be moved up and down and supporting the slider; a stopper formed with a stopper protrusion that catches the button and rotatably disposed between the button cover and the cover body; and a reset button disposed on the cover body to move the stopper in the forward and backward direction. A sliding protrusion is formed on the slider, and a rail along which the sliding protrusion is guided is formed on the housing.

## Claims

### Claim 1

A mirror assembly comprising;
a housing;
a support bracket rotatably disposed on the housing and coupled to a mirror; and
a tilting module mounted on the support bracket and tilting or untilting the support bracket relative to the housing,
wherein the tilting module comprises:
a slider slidably mounted on the support bracket;
a main spring disposed between the housing and the slider;
a button cover mounted on the support bracket;
a cover body coupled with the button cover;
a button disposed between the button cover and the cover body so as to be moved up and down and supporting the slider,
a stopper formed with a stopper protrusion that catches the button and rotatably disposed between the button cover and the cover body; and
a reset button disposed on the cover body to move the stopper in the forward and backward direction,
wherein a sliding protrusion is formed on the slider, and
a rail along which the sliding protrusion is guided is formed on the housing.

### Claim 2 (depends on 1)

The mirror assembly of claim 1,
wherein the rail comprises
a pair of straight portions spaced apart each other; and
a gradient connecting the pair of straight portions.

### Claim 3 (depends on 1)

The mirror assembly of claim 1,
wherein a virtual line connecting a starting point of the rail and an end point of the rail is inclined with respect to the housing.

### Claim 4 (depends on 1)

The mirror assembly of claim 1,
wherein the tilting module comprises
a stopper spring disposed between at least one of the button cover and the cover body and the stopper, the stopper elastically supporting the stopper in the rotational direction of the stopper; and
a reset spring disposed between the button cover and the stopper, the reset spring elastically supporting the stopper in the front and rear direction.

### Claim 5 (depends on 4)

The mirror assembly of claim 4,
wherein the stopper spring elastically supports the stopper at a locking angle at which the button is restrained by the stopper projection,
wherein the locking angle is a clockwise angle or a counterclockwise angle at which the button is restrained by the stopper projection,
wherein the reset spring elastically supports the stopper at a locking position at which the button is restrained by the stopper projection, and
wherein the locking position is a front and rear position at which the button is restrained by the stopper projection.

### Claim 6 (depends on 1)

The mirror assembly of claim 1,
wherein the support bracket comprises
a main bracket having a hinge axis receiving portion formed to accommodate a hinge axis formed on the housing; and
a cover bracket fastened to the main bracket.

### Claim 7 (depends on 1)

The mirror assembly of claim 1,
wherein a support axis is formed on at least one of the button cover and the cover body and rotatably and movably supports the stopper.

### Claim 8 (depends on 1)

The mirror assembly of claim 1,
wherein an avoidance hole is formed in the button for avoiding the stopper and the stopper spring.

### Claim 9 (depends on 1)

The mirror assembly of claim 1,
wherein a button protrusion is formed in the button and is restrained by the stopper protrusion in the up and down direction.

### Claim 10 (depends on 1)

The mirror assembly of claim 1,
wherein the tilting module further comprises
a damping spring disposed between the support bracket and the housing.
