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.

First claim

What is claimed is:

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 an auxiliary bracket configured to inhibit sagging of the front link toward the upper rail,
wherein the front link is pivotally coupled to the front link bracket,
wherein the front link and the auxiliary bracket are directly coupled to a first side of the front link bracket, respectively,
wherein the auxiliary bracket supports the front link by contacting with the front link when the front link sags,
wherein the auxiliary bracket is directly detachable from the front link bracket in a state where the front link is coupled to the front link bracket,
wherein the auxiliary bracket is 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, and
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.

2. The vehicle seat support assembly of claim 1 , further comprising: 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.

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

4. The vehicle seat support assembly of claim 1 , 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.

5. The vehicle seat support assembly of claim 1 , 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.

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

7. The vehicle seat support assembly of claim 6 , 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.

8. 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;
a front link pivotally coupled to the front link bracket; and
an auxiliary bracket configured to inhibit sagging of the front link toward the upper rail,
wherein the front link and the auxiliary bracket are directly coupled to a first side of the front link bracket, respectively,
wherein the auxiliary bracket supports the front link by contacting the front link when the front link sags,
wherein the auxiliary bracket is directly detachable from the front link bracket in a state where the front link is couple to the front link bracket,
wherein the auxiliary bracket is 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, and
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.

9. The vehicle seat support assembly of claim 8 , further comprising 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.

10. The vehicle seat support assembly of claim 9 , wherein the auxiliary link is movably coupled to a longitudinal slot-shaped guide formed in the front link bracket.
