Abstract

An easy entry seat assembly may include a seat frame having a seat bottom and a backrest. The seat frame may be connected to and/or supported by an easy entry mechanism relative to a support surface for movement between an upright seated position and a forward easy entry position. The seat frame may include a latch configured to lock the seat assembly in the upright seated position. An object detector may be provided on the seat frame to detect the presence of an object located in a path of the latch as the seat frame is moved from the forward easy entry position to the upright seated position.

Claims

1. An easy entry seat assembly comprising:

a seat frame having a seat bottom and a backrest;

an easy entry mechanism configured to support the seat frame relative to a support surface for movement between an upright seated position and a forward easy entry position;

a latch provided on the seat frame and configured to lock the seat frame in the upright seated position; and

an object detector provided on the seat frame to detect a presence of an obstacle located in a path of the latch as the seat frame is moved from the forward easy entry position to the upright seated position.

2. The easy entry seat assembly of claim 1, wherein the easy entry mechanism supports the seat frame on a pair of seat track assemblies.

3. The easy entry seat assembly of claim 1, wherein the seat frame is supported for pivotal movement between the upright seated position and the forward easy entry position.

4. The easy entry seat assembly of claim 1, wherein the latch includes a seat latch provided on the seat bottom.

5. The easy entry seat assembly of claim 1, wherein the object detector includes a mechanical component configured to detect the presence of an obstacle located in a path of the latch.

6. The easy entry seat assembly of claim 5, wherein the object detector includes an object detection shield provided on the seat frame adjacent to or near the latch.

7. The easy entry seat assembly of claim 6, wherein the object detection shield is a collapsible or flexible component, and a portion of the object detection shield is movable between a first or extended position and a second or collapsed position.

8. The easy entry seat assembly of claim 7, wherein the object detector further includes a probe provided between a portion of the seat frame and a movable portion of the object detection shield.

9. The easy entry seat assembly of claim 8, wherein the probe is configured to provide an output in response to movement of the object detection shield.

10. The easy entry seat assembly of claim 1, wherein the object detector includes an electrical component configured to detect the presence of an obstacle located in a path of the latch.

11. The easy entry seat assembly of claim 10, wherein the object detector includes a sensor provided on the seat frame adjacent to or near the latch.

12. The easy entry seat assembly of claim 11, wherein the sensor is a capacitive sensor.

13. The easy entry seat assembly of claim 11, wherein the sensor is configured to provide an output in response to detection of an object in the path of the latch.

14. An easy entry seat assembly for use in a vehicle, the easy entry seat assembly comprising:

a pair of seat track assemblies configured to be secured to a floor of the vehicle;

a seat frame having a seat bottom and a backrest;

an easy entry mechanism supporting the seat frame on the seat track assemblies for pivotal movement between an upright seated position and a forward easy entry position;

a latch provided on the seat frame for locking the seat frame in the upright seated position; and

an object detection device to detect a presence of an obstacle located in a path of the latch as the seat frame is moved from the forward easy entry position to the upright seated position.

15. The easy entry seat assembly of claim 14, wherein the object detection device includes an object detection shield provided on the seat frame adjacent to or near the latch.

16. The easy entry seat assembly of claim 15, wherein the object detection shield is a collapsible or flexible component, and a portion of the object detection shield is movable between a first or extended position and a second or collapsed position.

17. The easy entry seat assembly of claim 16, wherein the object detection device further includes a probe provided between a portion of the seat frame and a movable portion of the object detection shield.

18. The easy entry seat assembly of claim 14, wherein the object detection device includes an electrical component configured to detect the presence of an obstacle located in a path of the latch.

19. The easy entry seat assembly of claim 18, wherein the object detection device includes a sensor provided on the seat frame adjacent to or near the latch.

20. The easy entry seat assembly of claim 19, wherein the sensor is a capacitive sensor.
