LOCK DEVICE FOR VEHICULAR SEAT
PROBLEM TO BE SOLVED: To provide a lock device for a vehicular seat which is configured so as to suppress increase in operation force for releasing a lock state of the lock device even if enhancing turning energization force by which a cam presses a hook in a locked state in a lock direction.SOLUTION: The lock device for a vehicular seat comprises a striker 8 fixed to a floor and a lock mechanism 10 mounted on the vehicular seat. The lock mechanism 10 comprises a base plate 11, a hook 12, a pole 13, a cam 14 and an energizing plate 15. When a line connecting contact points of a hook shaft center 12PC, the cam 14 and the energizing plate 15 is defined as A, a line connecting contact points of the pole shaft center 13C, the cam 14 and the energizing plate 15 is defined as B, and a line in which B is projected in a direction perpendicular to an extension line of A with respect to the extension line of A is defined as C, the cam 14 and the energizing plate 15 are formed so that a value of C/A becomes larger as the cam 14 turns more so as to press the hook 12 in a lock direction.SELECTED DRAWING: Figure 5
【課題】カムがロック状態にあるフックをさらにロック方向へ押圧するための回動付勢力を高めても、ロック装置のロック状態を解除するための操作力の増加を抑制した乗物用シート用ロック装置を提供する。【解決手段】フロアに固定されたストライカ８と、自動車シートに取付けられたロック機構１０と、を備える。ロック機構１０は、ベースプレート１１と、フック１２と、ポール１３と、カム１４と、付勢プレート１５と、を備える。フック軸心１２ＰＣとカム１４と付勢プレート１５の当接点を結ぶ線をＡ、ポール軸心１３ＰＣとカム１４と付勢プレート１５の当接点を結ぶ線をＢ、Ａの延長線に対しＡの延長線に垂直な方向にＢを投影した線をＣとしたとき、カム１４がフック１２をロック方向に押圧するように回動するほどＣ／Ａの値が大きくなるようにカム１４と付勢プレート１５が形成されている。【選択図】図５
