Abstract

A seat adjuster assembly including a handle, a first track assembly and a second track assembly. The first track assembly includes a first track defining an interior and a second track moveably mounted relative to the first track. A first trigger is pivotally mounted on a first trigger housing and connects to the handle. The first trigger is movable between an unlocked position permitting movement between the first and second tracks, and a locked position. The second track assembly includes a third track defining an interior and a fourth track moveably mounted relative to the third track. A second trigger is pivotally mounted on a second trigger housing and connects to the handle. The second trigger is movable between an unlocked position permitting movement between the third and fourth tracks, and a locked position.

First claim

What is claimed is:

1. A seat adjuster assembly comprising:
a handle;
a first track assembly including:
a first track including a pair of spaced apart first track assembly side walls that define a first track assembly interior;
a second track supported on the first track for movement relative thereto;
a first trigger housing including a pair of spaced apart first trigger housing side walls that define a first trigger housing interior and that are respectively fixedly mounted to the pair of spaced apart first track assembly side walls within the interior of the first track assembly; and
a first trigger including a portion that is pivotally mounted on the pair of spaced apart first trigger housing side walls within the first trigger housing interior and that includes a portion that extends outwardly from the first trigger housing interior and is connected to the handle, the first trigger being movable between a locked position, wherein the first trigger prevents relative movement between the first and second tracks, and an unlocked position, wherein the first trigger permits movement between the first and second tracks; and

a second track assembly including:
a third track including a pair of spaced apart second track side walls that define a second track assembly interior;
a fourth track supported on the third track for movement relative thereto;
a second trigger housing including a pair of spaced apart second trigger housing side walls that define a second trigger housing interior and that are respectively fixedly mounted to the pair of spaced apart second track assembly side walls mounted within the interior of the second track assembly; and
a second trigger including a portion that is pivotally mounted on the pair of spaced apart second trigger housing side walls within the second trigger housing interior and that includes a portion that extends outwardly from the second trigger housing interior and is connected to the handle, the second trigger being movable between a locked position, wherein the second trigger prevents relative movement between the third and fourth tracks, and an unlocked position, wherein the second trigger permits movement between the third and fourth tracks;

wherein actuation of the handle causes the first trigger to move into the locked position prior to the second trigger moving into the locked position.

2. The seat adjuster assembly defined in claim 1 wherein actuation of the handle causes movement of both a first link that is located outwardly from the first trigger housing interior and is connected to move the first trigger and a second link that is located outwardly from the second trigger housing interior and is connected to move the second trigger.

3. The seat adjuster assembly defined in claim 2 wherein the first link is connected through a torsion bar to said second link.

4. The seat adjuster assembly defined in claim 1 wherein the first and second triggers are configured to move at different rates.

5. The seat adjuster assembly defined in claim 1 wherein the first and second triggers are configured to move from their unlocked positions to their locked positions at different rates.

6. The seat adjuster assembly defined in claim 1 wherein the first and second triggers are configured to move from their locked positions to their unlocked positions at different rates.

7. The seat adjuster assembly defined in claim 1 wherein the and second triggers are configured to move both (1) from their unlocked positions to their locked positions at different rates, and (2) from their locked positions to their unlocked positions at different rates.

8. The seat adjuster assembly defined in claim 1 wherein each of the pair of spaced apart first trigger housing side walls includes a recessed portion.

9. The seat adjuster assembly defined in claim 8 wherein each of the pair of spaced apart first trigger housing side walls includes first and second recessed portions.

10. The seat adjuster assembly defined in claim 1 wherein each of the pair of spaced apart first trigger housing side walls includes a recessed portion, and wherein each of the pair of spaced apart second trigger housing side walls includes a recessed portion.

11. The seat adjuster assembly defined in claim 10 wherein each of the pair of spaced apart first trigger housing side walls includes first and second recessed portions, and wherein each of the pair of spaced apart second trigger housing side walls includes first and second recessed portions.

12. The seat adjuster assembly defined in claim 1 wherein the pair of spaced apart first track assembly side walls are connected by a web.

13. The seat adjuster assembly defined in claim 12 wherein the pair of spaced apart second track assembly side walls are connected by a web.
