Slide rail device for vehicle

摘要

A slide rail device for a vehicle is provided, which can increase the rotatable range of a handle that is connected to a lock operational lever, and the operational force that is necessary for carrying out a lock release operation can be reduced, even if the rotatable range of the lock operational lever is limited to a narrow range by an upper rail.;The slide rail device includes a biaser 70 which rotatably biases the handle with respect to said lock operational lever in a direction so as to constantly maintain a supported state of a lower supported portion by a lower support portion and a supported state of an upper supported portion by an upper supporting portion.

主权项

1. A slide rail device for a vehicle comprising:
a lower rail which extends in a forward/rearward direction and is immovable relative to a floor of the vehicle; an upper rail which supports a seat and is supported by said lower rail to be slidable in said forward/rearward direction; a lower support portion provided on said upper rail, wherein said lower support portion extends inwardly from a side wall of said upper rail; a lock mechanism, provided between said upper rail and said lower rail, which restricts or releases restriction of sliding of said upper rail; a lock operational lever provided in an internal space of said upper rail, a portion of said lock operational lever which is rearward from said lower support portion being rotatably supported by said upper rail, and said lock operational lever being upwardly/downwardly rotatable between a locked position, at which the sliding restriction is allowed by the lock mechanism, and an unlocked position, at which a front portion of said lock operational lever moves further upward than said locked position to release said sliding restriction; an upper supporting portion provided on said lock operational lever, said upper supporting portion positioned further forward than said lower support portion and further upward than said lower support portion; a handle provided with a lower supported portion on an underside thereof which is rotatably supported by said lower support portion, and an upper supported portion on an upper side thereof which is positioned further forward than said lower supported portion and is rotatably supported by said upper supporting portion, said handle projecting forwardly from said lock operational lever; said handle and said lock operational lever are arranged to relatively rotate upward with each other when said lock operational lever is moved to said unlocked postion and said lower supported portion rotates while being supported at said lower support portion; and a biaser which rotatably biases said handle with respect to said lock operational lever in a direction so as to constantly maintain a supported state of said lower supported portion by said lower support portion and a supported state of said upper supported portion by said upper supporting portion.
