Reclining seat for a vehicle
A vehicle seat includes a track latch assembly having a lower track configured to couple to a vehicle floor, an upper track coupled to a seat base, a recline handle rotatably coupled to a seat bottom, and a track release mechanism configured to move between a disengaged position that enables relative sliding movement between the lower track and the upper track, and an engaged position that facilitates preventing relative sliding movement between the lower track and the upper track. Rotation of the recline handle is configured to move the track release mechanism from the engaged position to the disengaged position, and movement of the seat bottom from a lowered position to a raised position is configured to move the track release mechanism from the engaged position to the disengaged position. A pivot latch assembly prevents movement of the seat bottom to and from the lowered and raised positions.
1. A vehicle seat comprising:
a seat base;
a seat bottom frame pivotally coupled to the seat base such that the seat bottom frame is movable between a lowered position and a raised position;
a seat back pivotally coupled to the seat bottom frame; and
a track latch assembly configured to facilitate selective sliding movement of the seat base relative to a vehicle floor, comprising:
a lower track configured to couple to the vehicle floor;
an upper track coupled to the seat base;
a recline handle rotatably coupled to the seat bottom frame; and
a track release mechanism configured to move between a disengaged position that enables relative sliding movement between the lower track and the upper track, and an engaged position that facilitates preventing relative sliding movement between the lower track and the upper track,
wherein rotation of the recline handle is configured to move the track release mechanism from the engaged position to the disengaged position, and
wherein movement of the seat bottom frame from the lowered position to the raised position is configured to move the track release mechanism from the engaged position to the disengaged position.
2. The vehicle seat of claim 1 , further comprising:
a pivot latch assembly configured to facilitate selectively preventing movement of the seat bottom from the lowered position to the raised position, and from the raised position to the lowered position, the pivot latch assembly comprising:
a pendulum catch coupled to the seat bottom frame;
a pendulum support member fixed from rotation relative to the seat bottom frame and the pendulum catch; and
an inertial pendulum coupled to the pendulum support member, wherein during a vehicle impact event the inertial pendulum is configured to engage the pendulum catch to facilitate preventing rotational movement of the seat bottom frame.
3. The vehicle seat of claim 2 , wherein the pendulum catch comprises a main body portion, a first hook portion, and a second hook portion.
4. The vehicle seat of claim 3 , wherein when the seat bottom frame is in the lowered position, the inertial pendulum is oriented proximate the first hook portion and is configured to engage the first hook portion to facilitate preventing rotational movement of the seat bottom frame to the raised position, and
wherein when the seat bottom frame is in the raised position, the inertial pendulum is oriented proximate the second hook portion and is configured to engage the second hook portion to facilitate preventing rotational movement of the seat bottom frame to the lowered position.
5. The vehicle seat of claim 2 , wherein the pendulum catch is coupled to the seat bottom frame such that the pendulum catch rotates with the seat bottom frame.
6. The vehicle seat of claim 1 , wherein the track latch assembly further comprises:
a lever;
a pin coupled to the lever; and
a cable coupled between the pin and the track release mechanism, wherein movement of the seat bottom frame from the lowered position to the raised position causes a portion of the seat bottom frame to engage and move the lever and pin to cause movement of the cable.
7. The vehicle seat of claim 6 , wherein the lever comprises a first lever and a second lever rotatably coupled to the seat base, the pin coupled to at least one of the first and second levers.
8. The vehicle seat of claim 6 , wherein the pin extends into a slot formed in the seat base, the pin configured to travel along the slot.
9. The vehicle seat of claim 1 , further comprising a cable coupled between the recline handle and the track release mechanism.
10. A vehicle seat comprising:
a seat base;
a seat bottom frame pivotally coupled to the seat base such that the seat bottom frame is movable between a lowered position and a raised position;
a seat back pivotally coupled to the seat bottom frame; and
a track latch assembly configured to facilitate selective sliding movement of the seat base relative to a vehicle floor, comprising:
a lower track configured to couple to the vehicle floor;
an upper track coupled to the seat base;
a recline handle rotatably coupled to the seat bottom frame; and
a track release mechanism configured to move between a disengaged position that enables relative sliding movement between the lower track and the upper track, and an engaged position that facilitates preventing relative sliding movement between the lower track and the upper track,
a pivot latch assembly configured to facilitate selectively preventing movement of the seat bottom from the lowered position to the raised position, and from the raised position to the lowered position, comprising:
a pendulum catch coupled to the seat bottom frame;
a pendulum support member fixed from rotation relative to the seat bottom frame and the pendulum catch; and
an inertial pendulum coupled to the pendulum support member, wherein during vehicle impact event the inertial pendulum is configured to engage the pendulum catch to facilitate preventing rotational movement of the seat bottom frame;
wherein rotation of the recline handle is configured to move the track release mechanism from the engaged position to the disengaged position, and wherein movement of the seat bottom frame from the lowered position to the raised position is configured to move the track release mechanism from the engaged position to the disengaged position.
11. The vehicle seat of claim 10 , wherein the pendulum catch comprises a main body portion, a first hook portion, and a second hook portion.
12. The vehicle seat of claim 11 , wherein when the seat bottom frame is in the lowered position, the inertial pendulum is oriented proximate the first hook portion and is configured to engage the first hook portion to facilitate preventing rotational movement of the seat bottom frame to the raised position, and
wherein when the seat bottom frame is in the raised position, the inertial pendulum is oriented proximate the second hook portion and is configured to engage the second hook portion to facilitate preventing rotational movement of the seat bottom frame to the lowered position.
13. The vehicle seat of claim 10 , wherein the pendulum catch is coupled to the seat bottom frame such that the pendulum catch rotates with the seat bottom frame.
14. The vehicle seat of claim 10 , wherein the track latch assembly further comprises:
a lever;
a pin coupled to the lever; and
a cable coupled between the pin and the track release mechanism, wherein movement of the seat bottom frame from the lowered position to the raised position causes a portion of the seat bottom frame to engage and move the lever and pin to cause movement of the cable.
15. The vehicle seat of claim 14 , wherein the lever comprises a first lever and a second lever rotatably coupled to the seat base, the pin coupled to at least one of the first and second levers.
16. The vehicle seat of claim 14 , wherein the pin extends into a slot formed in the seat base, the pin configured to travel along the slot.
17. The vehicle seat of claim 10 , further comprising a cable coupled between the recline handle and the track release mechanism.
