Abstract

A vehicle slide rail device including a memory operation link which is configured to release a lock mechanism while leaving a memory member in a state of defining a default position, a holding link which is configured to, in response to an operation of the memory operation link, be engaged with the memory operation link by being biased and hold the memory operation link in a release operated position, a detection member which is configured to come into contact with a trigger member installed and be moved so as to release the holding state of the memory operation link at the release operated position, and a variable structure which is engaged with the pressing portion of the holding link and is configured to change a position where the pressing portion is arranged in the holding link according to a movement of the memory operation link.

First claim

What is claimed is:

1. A vehicle slide rail device comprising:
a slide rail which is capable of adjusting a seat position when a lock mechanism is released;
a memory mechanism which includes a memory member configured to define a default position, which is the seat position before change, by mechanical engagement to allow the seat position to return to the default position;
a memory operation link which is configured to release the lock mechanism while leaving the memory member in a state of defining the default position;
a holding link which is configured to, in response to an operation of the memory operation link, be engaged with the memory operation link by being biased and hold the memory operation link in a release operated position;
a detection member which is configured to, in response to moving the seat position in a state where the memory operation link is held by the holding link, press a pressing portion of the holding link by being brought into contact with a trigger member installed at a predetermined slide position and be moved so as to release the holding state of the memory operation link by the holding link at the release operated position; and
a variable structure which is provided in a state of being engaged with the pressing portion of the holding link and is configured to change a position where the pressing portion is arranged in the holding link according to a movement of the memory operation link,
wherein, in a state where the detection member is moved by being brought into contact with the trigger member, the variable structure is configured to arrange the pressing portion at a first position which is a position after the pressing portion is pressed by the detection member,
wherein, after the pressing portion has been arranged at the first position, as the memory operation link is operated and the holding link is engaged with the memory operation link by being biased, the variable structure is configured to move the pressing portion to a second position where an interference between the pressing portion and the detection member is avoided, and
wherein, after the pressing portion has been moved to the second position, as the detection member moves apart from the trigger member and changes its posture by the change of the seat position, the variable structure is configured to move the pressing portion to a third position at which the pressing portion is capable of being pressed by the detection member, the third position being located in an empty region from which the detection member has retreated due to the detection member changing its posture.

2. The vehicle slide rail device according to claim 1 ,
wherein the pressing portion includes a slide pin assembled in a slidable state in a first elongated hole formed in the holding link,
wherein the variable structure includes a control link having a second elongated hole extending so as to intersect with the first elongated hole formed in the holding link, and
wherein the slide pin is also assembled in a slidable state in the second elongated hole of the control link, and the slide pin slides within the first elongated hole and moves to the second position as the control link rotates according to the movement of the memory operation link.

3. The vehicle slide rail device according to claim 2 ,
wherein the control link is biased in a direction opposite to a rotation direction in which the slide pin moves toward to the second position, and after the control link rotates to move the slide pin to the second position in accordance with the movement of the memory operation link, as the memory operation link reaches a rotational position where the memory operation link is held at the release operated position by the holding link, the control link is released from an engagement state with the memory operation link and causes, by being biased, the slide pin to move on the detection member, and then, the slide pin is moved to the empty region in accordance with the detection member changing its posture.

4. The vehicle slide rail device according to claim 1 ,
wherein the trigger member includes the memory member.
