Abstract

A vehicle slide rail device including a release operation member which is configured to release a lock mechanism and slide together with a memory member in a slide direction by removing the memory member from a state of defining a default position; and a memory operation member which is configured to release the lock mechanism and maintain the released state while maintaining the memory member in the state of defining the default position, wherein the memory member has a receiving structure configured by an elastic structure by which the memory member is normally biased so as to maintain the state of defining the default position, and the memory member is pushed and tilted against the biasing by the movement of the release operation member, which is in an operated state, toward a predetermined operation position so that the release operation member is received into the predetermined operation position.

First claim

What is claimed is:

1. A vehicle slide rail device comprising:
a slide rail which is to adjust a seat position when a lock mechanism is released; and
a memory mechanism which includes a memory rail and a memory member configured to define a default position, which is the seat position before change, by mechanical engagement with the memory rail to allow the seat position to return to the default position;
a release operation member which is configured to release the lock mechanism and slide together with the memory member in a slide direction by disengaging the memory member from defining the default position; and
a memory operation member which is configured to release the lock mechanism and maintain the lock mechanism in a released state while maintaining the memory member defining the default position,
wherein the memory member has a receiving structure by which, when the release operation member has been operated to an operated state at a position offset from, in the slide direction, a predetermined operation position at which the memory member is operable and the release operation member is moved toward the memory member while maintaining the operated state, the release operation member is receivable into the predetermined operation position while maintaining the operated state, and
wherein the receiving structure includes an elastic structure by which the memory member is normally biased in a direction intersecting with the slide direction so as to maintain the memory member defining the default position, and the memory member is pushed and tilted against biasing by movement of the release operation member toward the predetermined operation position so that the release operation member is received into the predetermined operation position while maintaining the operated state.

2. The vehicle slide rail device according to claim 1 ,
wherein the operated state of the release operation member includes a state where the release operation member is pushed downward.

3. A vehicle slide rail device comprising:
a slide rail which is to adjust a seat position when a lock mechanism is released; and
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 release operation member which is configured to release the lock mechanism and slide together with the memory member in a slide direction by disengaging the memory member from defining the default position; and
a memory operation member which is configured to release the lock mechanism and maintain the lock mechanism in a released state while maintaining the memory member defining the default position,
wherein the memory member has a receiving structure by which, when the release operation member has been operated to an operated state at a position offset from, in the slide direction, a predetermined operation position at which the memory member is operable and the release operation member is moved toward the memory member while maintaining the operated state, the release operation member is receivable into the predetermined operation position while maintaining the operated state,
wherein the receiving structure includes an elastic structure by which the memory member is normally biased in a direction intersecting with the slide direction so as to maintain the memory member defining the default position, and the memory member is pushed and tilted against biasing by movement of the release operation member toward the predetermined operation position so that the release operation member is received into the predetermined operation position while maintaining the operated state, and
wherein the receiving structure is configured such that, as the release operation member is moved from one side in the slide direction toward the predetermined operation position, a region of the memory member on the one side in the slide direction is elastically pushed and tilted while the memory member defining the default position by the mechanical engagement is maintained at a region of the memory member on another side in the slide direction.

4. The vehicle slide rail device according to claim 3 ,
wherein the operated state of the release operation member includes a state where the release operation member is pushed downward.

5. The vehicle slide rail device according to claim 3 ,
wherein the memory mechanism further includes a memory rail, and the memory member is configured to define the default position by the mechanical engagement that is with the memory rail to allow the seat position to return to the default position.

6. A vehicle slide rail device comprising:
a slide rail which is to adjust a seat position when a lock is released; and
a memory mechanism which includes a memory rail and a memory slide configured to define a default position, which is the seat position before change, by mechanical engagement with the memory rail to allow the seat position to return to the default position;
a release operation lever which is configured to release the lock and slide together with the memory slide in a slide direction by disengaging the memory slide from defining the default position; and
a memory operation lever which is configured to release the lock and maintain the lock in a released state while maintaining the memory slide defining the default position,
wherein the memory slide has a receiving structure by which, when the release operation lever has been operated to an operated state at a position offset from, in the slide direction, a predetermined operation position at which the memory slide is operable and the release operation lever is moved toward the memory slide while maintaining the operated state, the release operation lever is receivable into the predetermined operation position while maintaining the operated state, and
wherein the receiving structure includes an elastic structure by which the memory slide is normally biased in a direction intersecting with the slide direction so as to maintain the memory slide defining the default position, and the memory slide is pushed and tilted against biasing by movement of the release operation lever toward the predetermined operation position so that the release operation lever is received into the predetermined operation position while maintaining the operated state.

7. The vehicle slide rail device according to claim 6 ,
wherein the receiving structure is configured such that, as the release operation lever is moved from one side in the slide direction toward the predetermined operation position, a region of the memory slide on the one side in the slide direction is elastically pushed and tilted while the memory slide defining the default position by the mechanical engagement is maintained at a region of the memory slide on another side in the slide direction.

8. The vehicle slide rail device according to claim 6 ,
wherein the operated state of the release operation lever includes a state where the release operation lever is pushed downward.
