## Abstract

A vehicle seat support assembly includes: a front link; and a front link bracket coupled to an upper rail of a vehicle seat and including a sagging support portion configured to inhibit sagging of the front link toward the upper rail. In particular, the front link is pivotally coupled to the front link.

## Claims

### Claim 1

A vehicle seat support assembly, comprising:
a front link; and
a front link bracket coupled to an upper rail of a vehicle seat and including a sagging support configured to inhibit sagging of the front link toward the upper rail,
wherein the front link is pivotally coupled to the front link.

### Claim 2 (depends on 1)

The vehicle seat support assembly of claim 1, wherein the sagging support comprises: a protrusion that extends from the front link bracket toward the front link and is spaced apart from the front link by a predetermined distance.

### Claim 3 (depends on 2)

The vehicle seat support assembly of claim 2, wherein the protrusion is formed integrally with the front link bracket.

### Claim 4 (depends on 1)

The vehicle seat support assembly of claim 1, wherein the sagging support comprises: an auxiliary bracket coupled to an inner portion of the front link bracket, disposed on an upper portion of the upper rail, and configured to support a lower side of the front link.

### Claim 5 (depends on 4)

The vehicle seat support assembly of claim 4, wherein the auxiliary bracket is detachably coupled to the front link bracket.

### Claim 6 (depends on 4)

The vehicle seat support assembly of claim 4, wherein a lower portion of the auxiliary bracket is in contact with and supported by the upper rail, and an upper portion of the auxiliary bracket is configured to support the front link.

### Claim 7 (depends on 6)

The vehicle seat support assembly of claim 6, wherein when the front link is in a position where a downward pivot movement is limited, the front link is in contact with the upper portion of the auxiliary bracket.

### Claim 8 (depends on 6)

The vehicle seat support assembly of claim 6, wherein when the front link is in a position where a downward pivot movement is limited, a predetermined distance is provided between the front link and the auxiliary bracket.

### Claim 9 (depends on 1)

The vehicle seat support assembly of claim 1, wherein the sagging support comprises: an auxiliary link having a first side fixedly coupled to the front link and a second side movably coupled to the front link bracket.

### Claim 10 (depends on 9)

The vehicle seat support assembly of claim 9, wherein a guide portion is formed in the front link bracket, and the second side of the auxiliary link is movably coupled to the guide portion and movable along a longitudinal direction of the front link bracket.

### Claim 11

A vehicle seat support assembly comprising:
a lower rail;
an upper rail slidably mounted on the lower rail and including a first portion that is projected beyond the lower rail by a first length;
a front link bracket coupled to the first portion and extending along the upper rail for a distance longer than the first length; and
a front link pivotally coupled to the front link bracket.

### Claim 12 (depends on 11)

The vehicle seat support assembly of claim 11, further comprising a sagging support portion configured to inhibit sagging of the front link toward the upper rail.

### Claim 13 (depends on 12)

The vehicle seat support assembly of claim 12, wherein the sagging support portion comprises any one of:
a protrusion that extends from the front link bracket toward the front link and is spaced apart from the front link by a predetermined distance;
an auxiliary bracket coupled to the front link bracket and configured to support a lower side of the front link; or
an auxiliary link including: a first side fixedly coupled to the front link, and a second side configured to be coupled to and move along the front link bracket.

### Claim 14 (depends on 13)

The vehicle seat support assembly of claim 13, wherein the auxiliary link is movably coupled to a longitudinal slot-shaped guide formed in the front link bracket.
