## Abstract

A mount base for a rearview mirror includes: a base body including a first material; and an insert embedded in the base body and including a second material. The base body has a first surface and a second surface opposing the first surface, the insert has a first surface and a second surface opposing the first surface, the first material is softer than the second material, and the second material has higher stiffness than the first material.

## Claims

### Claim 1

A mount base for a rearview mirror, the mount base comprising:
a base body including a first material;
an insert embedded in the base body, and including a second material; and
at least one stress absorbing member embedded in the base body,
wherein the base body has a first surface and a second surface opposing the first surface,
wherein the insert has a first surface and a second surface opposing the first surface,
wherein the first material is softer than the second material,
wherein the second material has higher stiffness than the first material,
wherein the base body and the insert form a unitary one-piece structure,
wherein the insert includes a slot provided in the center thereof, and
wherein the stress absorbing member is overlapped with the slot of the insert.

### Claim 2 (depends on 1)

The mount base according to claim 1, wherein the insert includes a plurality of holes.

### Claim 3 (depends on 1)

The mount base according to claim 1, wherein the insert includes a plurality of recesses provided in a side edge, an end portion, or a side edge and end portion thereof.

### Claim 4 (depends on 1)

The mount base according to claim 1,
wherein a longitudinal axis of the slot is aligned with a longitudinal axis of the insert.

### Claim 5 (depends on 4)

The mount base according to claim 4, wherein the insert further includes a closed wall by which the slot is closed.

### Claim 6 (depends on 4)

The mount base according to claim 4, further comprising a third material with which the slot is filled,
wherein the third material is the same material as the first material or is softer than the first material.

### Claim 7 (depends on 1)

The mount base according to claim 1, wherein a thickness of the insert is less than that of the base body.

### Claim 8 (depends on 1)

The mount base according to claim 1, wherein the first surface of the insert is offset from the first surface of the base body toward the second surface of the base body, and
wherein the second surface of the insert is offset from the second surface of the base body toward the first surface of the base body.

### Claim 9 (depends on 1)

The mount base according to claim 1, wherein the first surface of the insert is offset from the first surface of the base body toward the second surface of the base body, and
wherein the second surface of the insert is flush with the second surface of the base body.

### Claim 10 (depends on 1)

The mount base according to claim 1, wherein the first surface of the insert is flush with the first surface of the base body, and
wherein the second surface of the insert is offset from the second surface of the base body toward the first surface of the base body.

### Claim 11 (depends on 1)

The mount base according to claim 1, wherein the insert is curved with a predetermined curvature.

### Claim 12 (depends on 1)

The mount base according to claim 1, wherein the insert further includes a transverse rib extending along a width direction of the insert and a longitudinal rib extending along a longitudinal direction of the insert.

### Claim 13 (depends on 1)

The mount base according to claim 1, wherein the insert further includes at least one support projection extending from an end portion of the insert to an end portion of the base body.

### Claim 14 (depends on 1)

The mount base according to claim 1,
wherein the stress absorbing member includes a fourth material, which is softer than the first material.

### Claim 15 (depends on 1)

The mount base according to claim 1, further comprising a first stress absorbing member embedded in the base body and aligned with a slot of the insert,
wherein the first stress absorbing member contacts the first surface of the insert.

### Claim 16 (depends on 1)

The mount base according to claim 1, further comprising a second stress absorbing member embedded in the base body and aligned with a slot of the insert,
wherein the second stress absorbing member contacts the second surface of the insert.

### Claim 17 (depends on 1)
