Claims

1. A seat assembly comprising: a track assembly configured to position the seat assembly; anda cartridge assembly disposed at least partially inside the track assembly for dampening motion of the seat assembly.

2. The seat assembly of claim 1 wherein the track assembly further comprises an outer track and an inner track received by the outer track, wherein the cartridge assembly is at least partially disposed between the inner and outer tracks.

3. The seat assembly of claim 1 wherein the cartridge assembly further comprises a bracket portion mounted to the track assembly and a cartridge portion disposed at least partially inside the track assembly.

4. The seat assembly of claim 3 wherein the cartridge portion further comprises a spring disposed inside the track assembly that provides a biasing force for dampening movement of the seat assembly.

5. The seat assembly of claim 3 wherein the bracket portion further comprises an actuator plate and the cartridge portion further comprises a trigger, wherein the actuator plate is operatively associated with the trigger to engage or disengage the trigger from the track assembly.

6. The seat assembly of claim 5 wherein the actuator plate further comprises an elongated slot that permits at least a portion of the track assembly to move relative to the trigger.

7. The seat assembly of claim 6 wherein the elongated slot further comprises a detent notch, wherein the movement of the track assembly is inhibited when the trigger is coupled to the detent notch.

8. A seat assembly comprising: a track assembly having an outer track and an inner track received by the outer track; anda cartridge assembly having a bracket portion disposed adjacent to the inner track and a cartridge portion having a trigger;wherein the cartridge portion dampens motion of the inner track when the trigger is interlocked with the outer track and sufficient force is provided to move the bracket portion with respect to the cartridge portion.

9. The seat assembly of claim 8 wherein the cartridge portion further comprises a housing fixedly coupled to the inner track.

10. The seat assembly of claim 9 wherein the cartridge portion further comprises a block disposed in and adapted to move relative to the housing.

11. The seat assembly of claim 10 wherein the block further comprises a slot that receives a trigger.

12. The seat assembly of claim 10 wherein the cartridge portion further comprises a rod that extends from the block and through a hole in an end wall of the housing.

13. The seat assembly of claim 12 wherein the cartridge portion further comprises a spring disposed between the block and the end wall for providing a biasing force to dampen motion of the inner track.

14. The seat assembly of claim 13 wherein the spring is disposed about the rod.

15. The seat assembly of claim 10 wherein the inner track includes an inner track slot that receives the trigger, wherein the inner track slot is configured to allow the inner track to move about the trigger when the trigger engages the outer track.

16. A seat assembly comprising: a track assembly having an inner track and an outer track; anda cartridge assembly including: a bracket portion disposed adjacent to the inner track, the bracket portion including a bracket, a pivot plate moveably coupled to the bracket, and an actuator plate having an elongated slot; anda cartridge portion having a block and a trigger moveably received by the block and operatively associated with the actuator plate;wherein the inner track is permitted to move relative to the outer track when the trigger is disengaged from the outer track or when the trigger is engaged with the outer track and the actuator plate moves relative to the trigger.

17. The seat assembly of claim 16 wherein the bracket further comprises a guide flange having an opening for moveably receiving the actuator plate, wherein the actuator plate moves within the opening when actuated by the pivot plate.

18. The seat assembly of claim 16 further comprising a pin that extends through the elongated slot and is fixedly coupled to the trigger.

19. The seat assembly of claim 18 wherein the cartridge assembly further comprises a housing disposed in the inner track, a rod extending from the block through a hole in the housing, and a spring disposed around the rod for providing a biasing force to dampen movement of the seat when the pin moves within the elongated slot.

20. The seat assembly of claim 18 wherein the elongated slot includes a detent notch, wherein dampening operation of the cartridge assembly is deactivated when the pin is disposed in the detent notch.
