PROBLEM TO BE SOLVED: To provide a seat rail device for a vehicle having a pair of seat rails on both the left and right sides of a seat cushion of a vehicle according to at least one embodiment of this invention, which can surely prevent a so-called "single locking" state where a locking member operates only in a regular position of one seat rail.SOLUTION: The seat rail device for a vehicle comprises a first moving mechanism 55, locking member casings 29, 31, 33, and a second moving mechanism 57. The first moving mechanism 55 causes a locking member to advance and retract in engagement and separated directions with respect to a locked part in response to an operation of a seat lock lever by occupants. The locking member casings 29, 31, 33 are attached to upper rails and store the locking members movably in the engagement and separated directions, and in the sliding direction of the upper rails. The second moving mechanism 57 is provided inside the locking member casing and allows the locking member to engage with the locked part by moving the locking member to a position opposite the locked part using moving force of the locking member in the engagement direction due to the first moving mechanism.SELECTED DRAWING: Figure 3
【課題】本発明の少なくとも一実施形態は、車両のシートクッションの左右両側に一対のシートレールを有するシートレール装置において、一方のシートレールだけが正規位置でロック部材が作動している所謂「片ロック」状態を確実に防止できる車両用シートレール装置を提供することを目的とする。【解決手段】乗員のシートロックレバーの操作に連動して被ロック部に対してロック部材を係合及び離脱方向に進退せしめる第1移動機構55と、アッパレールに取り付けられ、係合及び離脱方向及びアッパレールのスライド方向に移動可能にロック部材を収納するロック部材ケーシング29、31、33と、ロック部材ケーシング内に設けられ、第1移動機構によるロック部材の係合方向への移動力によってロック部材を被ロック部に正対する位置に移動せしめて被ロック部への係合を可能にする第2移動機構57と、を備える。【選択図】図3
