Abstract

A vehicle seat including a fixed rail assembly, a translatable rail, and a translatable bracket. The fixed rail assembly includes a fixed rail and a fixed bracket extending from the fixed rail assembly. The translatable rail is configured to translate in a longitudinal direction along the fixed rail. The translatable bracket is fixed relative to the translatable rail such that the translatable rail and the translatable bracket translate in unison. The translatable bracket is configured to retain portions of the translatable rail within portions of the fixed rail. The translatable bracket includes a translating stop. The translatable rail is configured to translate between a first position in which the translating stop engages a fixed stop and a second position in which the translating stop is spaced apart from the translating stop.

First claim

What is claimed is:

1. A motor vehicle seat comprising:
a fixed rail assembly including a fixed rail and a fixed bracket extending from the fixed rail, the fixed bracket forming a fixed stop;
a translatable rail configured to translate in a longitudinal direction along the fixed rail; and
a translatable bracket fixed relative to the translatable rail such that the translatable rail and the translatable bracket translate in unison, the translatable bracket being configured to retain portions of the translatable rail within portions of the fixed rail, wherein the translatable bracket includes a translating stop;
wherein the translatable rail is configured to translate between a first position in which the translating stop engages the fixed stop, and a second position in which the translating stop is spaced from the fixed stop,
wherein the translatable bracket includes a leading end and a trailing end, each positioned with respect to the longitudinal direction, wherein the translatable stop is disposed between the leading and trailing ends, such that a portion of the translatable bracket overlaps the fixed stop when the translatable stop is engaged with the fixed stop.

2. The motor vehicle seat of claim 1 , wherein the fixed bracket includes a first hook and the translatable bracket includes a second hook, and wherein the first hook engages the second hook in response to a force exceeding a threshold is applied to the translatable rail in a direction oblique to the longitudinal direction.

3. The motor vehicle seat of claim 2 , wherein the translating stop extends towards the translatable rail and overlaps the fixed bracket.

4. The motor vehicle seat of claim 2 , wherein the fixed rail is attachable to a vehicle floor wherein the fixed stop extends away from the vehicle floor and the first hook includes a distal end that extends towards the vehicle floor.

5. The motor vehicle seat of claim 1 , further comprising:
a cushion carrier; and
a coupling bracket fixed to the translatable rail and coupled to the cushion carrier, wherein the translatable bracket is directly fixed to the cushion carrier and/or the coupling bracket.

6. The motor vehicle seat of claim 1 , wherein the translatable stop is a tab extending from a main body of the translatable bracket.

7. The motor vehicle seat of claim 1 , wherein the fixed stop is a tab extending from a main body of the fixed bracket.

8. A motor vehicle seat comprising:
a cushion carrier;
a fixed rail assembly including a fixed rail;
a translatable rail assembly including a translatable rail configured to translate in a longitudinal direction along the fixed rail;
a fixed bracket; and
a translatable bracket fixed to the cushion carrier and/or the translatable rail assembly, the translatable bracket being configured to retain portions of the translatable rail within portions of the fixed rail, wherein translatable bracket includes a translating stop;
wherein the translatable rail is configured to translate between a first position in which the translating stop engages a fixed stop, and a second position in which the translating stop is spaced from the fixed stop,
wherein the translatable bracket includes a leading end and a trailing end, each positioned with respect to the longitudinal direction, wherein the translating stop is disposed between the leading and trailing ends, such that a portion of the translatable bracket overlaps the fixed stop when the translating stop is engaged with the fixed stop.

9. The motor vehicle seat of claim 8 , wherein in an installed state, the fixed rail and the fixed bracket are each fixed to a vehicle floor.

10. The motor vehicle seat of claim 8 , wherein the fixed bracket includes a fixed hook extending from a main body of the fixed bracket, wherein a main body of the translatable bracket is substantially parallel to an end portion of the fixed hook.

11. A rail assembly for use in a motor vehicle seat, the rail assembly comprising:
a fixed rail;
a translatable rail configured to translate in a longitudinal direction along the fixed rail;
a fixed bracket including a fixed stop, wherein the fixed bracket is directly connected to the fixed rail; and
a translatable bracket fixed relative to the translatable rail such that the translatable rail and the translatable bracket translate in unison, the translatable bracket being configured to retain portions of the translatable rail within portions of the fixed rail, wherein translatable bracket includes a translating stop;
wherein the translatable rail is configured to translate between a first position in which the translating stop engages a fixed stop, and a second position in which the translating stop is spaced from the fixed stop,
wherein the translatable bracket includes a first protrusion extending from a main body of the translatable bracket and portions of the main body of the translatable bracket cover the fixed stop when the translatable stop is spaced apart from the fixed stop by a first distance and the portions of the main body of the translatable bracket do not cover the fixed stop when the translatable stop is spaced apart from the fixed stop by a second distance, and wherein the second distance is greater than the first distance.

12. The rail assembly of claim 11 , wherein the fixed bracket includes a rearward fixed stop and the translatable rail is configured to translate between a forward-most position and a rearward-most position in which the translating stop engages the rearward stop.

13. The rail assembly of claim 12 , wherein the first position is the forward-most position and the second position is disposed between the forward-most position and the rearward-most position.

14. The rail assembly of claim 13 , wherein the fixed bracket includes a rearward end and a forward end, and the rearward end includes the rearward stop.

15. The rail assembly of claim 14 , wherein the translatable bracket includes a leading end and a trailing end, each positioned with respect to the longitudinal direction, wherein the translating stop forms a portion of the leading end.
