Abstract

A vehicle slide rail device including: a memory mechanism which includes a memory member configured to define a default seat position by engagement; a release operation mechanism which is configured to release a lock mechanism from a locked state and slide together with the memory member in a slide direction by removing the memory member from a state of defining the default seat position; a memory operation mechanism which is configured to release the lock mechanism from the locked state while leaving the memory member in the state of defining the default seat position; a cancel mechanism which is pressed against the memory member to cancel the releasing of the lock mechanism by the memory operation mechanism and return the lock mechanism to the locked state when the seat position is returned to the default seat position defined while an operated state of a memory operation member is maintained.

Claims

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 release operation mechanism which is configured to release the lock mechanism from a locked state and slide together with the memory member in a slide direction by removing the memory member from a state of defining the default position;

a release operation member which is configured to operate the release operation mechanism by transmitting an operating force to the release operation mechanism;

a memory operation mechanism which is configured to release the lock mechanism from the locked state while leaving the memory member in the state of defining the default position;

a memory operation member which is configured to be operated into an operated state in which an operating force is transmitted to the memory operation mechanism so as to operate the memory operation mechanism and which is configured to return the memory operation mechanism to a state before the operation when the memory operation member is returned from the operated state; and

a cancel mechanism which is pressed against the memory member to cancel the releasing of the lock mechanism by the memory operation mechanism and return the lock mechanism to the locked state when the seat position is returned to the default position defined by the memory member while the operated state of the memory operation member is maintained.

2. The vehicle slide rail device according to claim 1,

wherein the cancel mechanism includes a one-way operation structure which allows the lock mechanism to return to the locked state by pressing a contact part configuring a power transmission path of the memory operation mechanism from a first direction and releasing the contact part from a contact state in which power transmission is capable when the cancel mechanism is pressed against the memory member by returning the seat position to the default position, and which maintains the contact part in the contact state in which power transmission is capable without moving the contact part when the cancel mechanism is pressed against the contact part from a second direction different from the first direction by changing the seat position from the default position by operating the memory operation member.
