Abstract

The present application relates to a striker assembly and a seat assembly. A striker assembly includes a motor, a worm screw operably coupled with the motor, a gear segment engaged with the worm screw, and a striker connected to the gear segment and configured for engagement with a latch of a seat back of the seat to adjustably couple the seat back with a mounting surface.

First claim

What is claimed is:

1 . A striker assembly for a seat, wherein the striker assembly comprises:
a motor; a worm screw operably coupled with the motor; a gear segment engaged with the worm screw; and a striker connected to the gear segment and configured for engagement with a latch of a seat back of the seat to adjustably couple the seat back with a mounting surface.

2 . The striker assembly of claim 1 , wherein the striker assembly includes a housing;
the worm screw and the gear segment are disposed at least partially in the housing; and the housing is configured for connection with said mounting surface.

3 . The striker assembly of claim 2 , wherein the housing includes a slot; and
the striker extends from the gear segment out of the housing through the slot.

4 . The striker assembly of claim 2 , wherein the housing includes a bearing slidably supporting an inner radial surface of the gear segment.

5 . The striker assembly of claim 4 , wherein the striker is connected to the gear segment such that the striker slides with the gear segment relative to the housing.

6 . The striker assembly of claim 4 , wherein the gear segment includes a slot; and
the housing includes a second bearing disposed partially in the slot of the gear segment.

7 . The striker assembly of claim 1 , wherein the gear segment includes a structural layer.

8 . The striker assembly of claim 1 , wherein the gear segment includes a structural layer and additional layer configured to reduce play between the gear segment and the worm screw.

9 . The striker assembly of claim 1 , wherein the worm screw is engaged with at least four gear segment teeth of the gear segment.

10 . The striker assembly of claim 1 , wherein the striker assembly includes a housing;
a first bearing strip disposed at a first side of the gear segment; and a second bearing strip disposed at a second side of the gear segment; wherein the first bearing strip and the second bearing strip restrict transverse movement of the gear segment.

11 . The striker assembly of claim 10 , wherein the first bearing strip is integrally formed with the housing.

12 . A seat assembly, wherein the seat assembly comprises:
the striker assembly of claim 1 ; the seat, including the seat back, a seat frame, and a seat base, the seat back rotatably coupled to the seat frame and/or the seat base; and the latch; wherein the latch is connected to the seat back and is selectively engageable with the striker.

13 . The seat assembly of claim 12 , wherein the striker includes an aperture;
in a disengaged state of the latch, the latch is not disposed in the aperture; and in an engaged state of the latch, a portion of the latch is disposed in the aperture.

14 . The seat assembly of claim 12 , wherein the motor, the worm screw, the gear segment, and the striker are operably coupled such that, when the latch is engaged with the striker, actuation of the motor causes rotation of the seat back.

15 . The seat assembly of claim 12 , wherein the gear segment includes a first gear segment position and a second gear segment position; and
in an engaged state of the latch (i) the seat back is disposed at a first rotational position when the gear segment is in the first gear segment position, and (ii) the seat back is disposed at a second rotational position when the gear segment is in the second gear segment position.

16 . The seat assembly of claim 15 , wherein a difference between the first and second rotational positions is greater than 2 degrees and less than 90 degrees.

17 . The seat assembly of claim 12 , wherein the seat back rotates about an axis of rotation; and the gear segment defines a portion of a circle centered at the axis of rotation.

18 . The seat assembly of claim 17 , wherein an angular extent of the gear segment is less than or equal to 90 degrees and greater than or equal to 2 degrees.

19 . The seat assembly of claim 17 , wherein a worm axis of the worm screw is disposed at an angle equal to or between 80 degrees and 100 degrees relative to the axis of rotation.

20 . The seat assembly of claim 19 , wherein a motor axis of the motor is parallel with the axis of rotation.
