Abstract

A release mechanism of a seat, including a two way motion actuator that moves in both a first direction and in a second direction; a recliner release mechanism that releases a recliner of the seat in response to the two way motion actuator moving in the first direction; and a slide release mechanism that releases a slide mechanism of the seat in response to the two way motion actuator moving in the second direction. The release mechanism also including a first unintentional movement prevention device that prevents the slide mechanism from being released when the two way motion actuator moves in the first direction; and a second unintentional movement prevention device that prevents the recliner from being released when the two way motion actuator moves in the second direction.

Claims

1. A release mechanism of a seat, comprising:

a two way motion actuator that moves in both a first direction and in a second direction;

a recliner release mechanism that releases a recliner of the seat in response to the two way motion actuator moving in the first direction;

a slide release mechanism that releases a slide mechanism of the seat in response to the two way motion actuator moving in the second direction;

a push pull link that extends from the two way motion actuator to a rotation link, the rotation link rotating in response to movement by the two way motion actuator; and

a center rotation link that is connected to the rotation link by a half tube that extends from the rotation link.

2. The release mechanism of the seat according to claim 1, further comprising:

a first movement device that prevents the slide mechanism from moving when the two way motion actuator moves in the first direction; and

a second movement device that prevents the recliner from moving when the two way motion actuator moves in the second direction.

3. The release mechanism of the seat according to claim 1, wherein the two way motion actuator is a motor and the first direction is a first rotation direction of the motor and the second direction is a second rotation direction of the motor.

4. The release mechanism of the seat according to claim 2, wherein the first movement device and the second movement device are slot holes.

5. The release mechanism of the seat according to claim 2, wherein the recliner release mechanism includes a recliner release lever that releases the recliner of the seat, and a recliner pull link that is connected to the center rotation link by a first riveting and connected to the recliner release lever by a second riveting.

6. The release mechanism of the seat according to claim 5, wherein the recliner pull link includes a first slot hole in which the second riveting is configured to slide.

7. The release mechanism of the seat according to claim 6, wherein the first movement device is the first slot hole and when the two way motion actuator moves in the first direction the second riveting contacts an end of the first slot hole so that the recliner pull link moves the recliner release lever and when the two way motion actuator moves in the second direction the second riveting slides within the first slot hole and recliner release lever is unmoved by the center rotation link.

8. The release mechanism of the seat according to claim 2, wherein the slide release mechanism includes a slide release lever that releases the slide mechanism of the seat, and the slide release lever is connected to the to the center rotation link by a slide pin that extends from the center rotation link.

9. The release mechanism of the seat according to claim 8, wherein the slide release lever includes a second slot hole in which the slide pin is configured to slide.

10. The release mechanism of the seat according to claim 9, wherein the second movement device is the second slot hole and when the two way motion actuator moves in the second direction the slide pin contacts an end of the second slot hole so that the slide release lever is moved to release the slide mechanism and when the two way motion actuator moves in the first direction the slide pin slides within the second slot hole and slide release lever is unmoved by the center rotation link.

11. The release mechanism of the seat according to claim 1, wherein if electric power is disconnected from the two way motion actuator then each of the recliner release mechanism and the slide release mechanism are placed in a locked state.
