Abstract

A seat assembly includes a seat frame having a first end connected to a vehicle and a second end cooperating with a latching system having a latching mechanism to releasably secure to at least one receiving portion. A seat structure adjustably positionable on the seat frame includes a seat bottom and a seat back pivotally connected to the seat structure. A seat adjustment system includes a first guide member proximate the latching mechanism having a first channel portion and a second guide member proximate the seat structure having a second channel portion configured to align with the first channel portion. A coupling element operatively connected to a first actuator includes an elongate projection that is translated from a locked position in the first channel portion to an unlocked position in the second channel portion to release the latching mechanism from the at least one receiving portion.

First claim

1 . A seat assembly for use in a vehicle comprising:
a seat frame having a first end connected to the vehicle and a second end; a seat structure adjustably positionable between the first and second ends of the seat frame having a seat bottom and a seat back pivotally connected to the seat structure; a latching system cooperating with the seat frame having at least one receiving portion and a latching mechanism disposed on the seat frame releasably secured to the at least one receiving portion; and a seat adjustment system operatively connected to the latching system to adjustably position the seat frame relative to the vehicle including
a first guide member proximate the latching mechanism having a first channel portion,
a second guide member proximate the seat structure having a second channel portion configured to align with the first channel portion,
a first actuator operatively connected to the latching mechanism to releasably secure the latching mechanism to the at least one receiving portion, and
a coupling element cooperating with the first actuator having an elongate projection at least partially received within the first channel portion movable between a locked position in the first channel portion and an unlocked position in the second channel portion,
wherein the seat structure is adjusted on the seat frame to align the second channel portion on the second guide member with the first channel portion on the first guide member to move the elongate projection from the locked position to the unlocked position in the second channel portion to release the latching mechanism from the at least one receiving portion.

2 . The seat assembly of claim 1 further comprising at least one indicia provided on at least one of the first guide member and second guide member to indicate when the first channel portion and the second channel portion are in alignment.

3 . The seat assembly of claim 2 wherein at least one indicia is provided on the first guide member and aligned with at least one indicia provided on the second guide member when the seat structure is adjusted on the seat frame to align the second channel portion on the second guide member with the first channel portion on the first guide member.

4 . The seat assembly of claim 1 wherein the seat structure includes at least one track mount operatively connected to at least one track channel on the seat frame to move the seat structure relative to the seat frame.

5 . The seat assembly of claim 4 further comprising a second actuator selectively engaging a release mechanism cooperating with the at least one track mount to position the seat structure relative to the seat frame to the first channel portion on the first guide member with the second channel portion on the second guide member.

6 . The seat assembly of claim 1 further comprising an adjustment mechanism for selectively adjusting the seat back relative to the seat bottom between a seated position and a folded position wherein the seat back is placed proximate the seat bottom.

7 . The seat assembly of claim 1 wherein the first end of the seat frame is pivotally connected to a floor of the vehicle to adjust the seat frame between a first position wherein the seat frame is positioned proximate the vehicle floor and a second position wherein the seat frame pivots about the first end.

8 . The seat assembly of claim 1 wherein the first guide member is secured to a portion of the latching mechanism.

9 . The seat assembly of claim 1 wherein the second guide member is secured to a portion of the seat structure.

10 . A seat assembly for use in a vehicle passenger compartment comprising:
a seat frame having a first end pivotally connected to the passenger compartment and a second end; a seat structure adjustably positionable between the first and second ends of the seat frame having a seat bottom and a seat back pivotally connected to the seat structure; an adjustment mechanism selectively adjusting the seat back relative to the seat bottom between a seating position and a folded position wherein the seat back is placed proximate the seat bottom; a latching system cooperating with the seat frame having at least one receiving portion and a latching mechanism disposed on the seat frame releasably secured to the at least one receiving portion; and a seat adjustment system operatively connected to the latching system to adjustably position the seat frame relative to the vehicle including
a first guide member proximate the latching mechanism having a first channel portion,
a second guide member proximate the seat structure having a second channel portion configured to align with the first channel portion,
at least one indicia provided on at least one of the first guide member and second guide member,
a first actuator operatively connected to the latching mechanism to releasably secure the latching mechanism to the at least one receiving portion, and
a coupling element cooperating with the first actuator having an elongate projection at least partially received within the first channel portion movable between a locked position in the first channel portion and an unlocked position in the second channel portion,
wherein the seat structure is adjusted on the seat frame to align the second channel portion on the second guide member with the first channel portion on the first guide member to move the elongate projection from the locked position to the unlocked position in the second channel portion to release the latching mechanism from the at least one receiving portion.

11 . The seat assembly of claim 10 wherein the at least one indicia provided on the first guide member is aligned with at least one indicia provided on the second guide member to indicate alignment of the first channel portion and the second channel portion.

12 . The seat assembly of claim 10 wherein the seat structure includes at least one track mount operatively connected to at least one track channel on the seat frame to move the seat structure relative to the seat frame.

13 . The seat assembly of claim 12 further comprising a second actuator selectively engaging a release mechanism cooperating with the at least one track mount to position the seat structure relative to the seat frame to the first channel portion on the first guide member with the second channel portion on the second guide member.

14 . The seat assembly of claim 10 wherein the seat frame is adjustable between a first position wherein the seat frame is positioned proximate the passenger compartment and a second position wherein the seat frame pivots about the first end.

15 . The seat assembly of claim 10 wherein the first guide member is secured to a portion of the latching mechanism.

16 . The seat assembly of claim 10 wherein the second guide member is secured to a portion of the seat structure.

17 . A vehicle seat adjustment system comprising:
a latching system having at least one receiving portion and a latching mechanism releasably secured to the at least one receiving portion; a first guide member having a first channel portion; a second guide member having a second channel portion configured to align with the first channel portion; at least one indicia provided on at least one of the first guide member and second guide member; and a coupling element having an elongate projection at least partially received within the first channel portion movable between a locked position in the first channel portion and an unlocked position in the second channel portion.
