Abstract:
(EN) A vehicle seat (1) is provided with a reclining part (10) that supports, in a manner such that the tilt angle is variable, a portion of a seatback (3) above the lower end thereof, wherein the reclining part (10) has: a link (12) which is capable of oscillating forward and backward of the seat, and which supports the seatback (3) at a oscillation end (22); a gear (13) which has a plurality of gear teeth arranged in a circular arc configuration with an oscillation shaft (C) of the link (12) being disposed at the center, and which is rotated integrally with the link (12); a gear lock (14) which is capable of sliding between an engaging position at which meshing with the gear (13) takes place and a non-engaging position at which meshing with the gear is released; a cam (15) which is capable of rotating between a first posture in which the gear lock (14) is moved to the engaging position and a second posture in which the gear lock (14) is allowed to move to the non-engaging position; and an operation part for operating the rotation of the cam (15).
(FR) L'invention concerne un siège de véhicule (1) comprenant une partie inclinable (10) qui supporte, d'une manière telle que l'angle d'inclinaison soit variable, une portion d'un dossier de siège (3) au-dessus de son extrémité inférieure, la partie inclinable (10) comprenant : une liaison (12) qui est apte à osciller vers l'avant et vers l'arrière du siège et qui supporte le dossier de siège (3) au niveau d'une extrémité d'oscillation (22) ; un engrenage (13) qui a une pluralité de dents d'engrenage disposées dans une configuration d'arc circulaire avec un arbre d'oscillation (C) de la liaison (12) disposé au centre et qui est entraîné en rotation d'un seul tenant avec la liaison (12) ; un verrou d'engrenage (14) qui est apte à coulisser entre une position de mise en prise dans laquelle un engrènement avec l'engrenage (13) se produit et une position de désengagement dans laquelle l'engrènement avec l'engrenage est relâché ; une came (15) qui est apte à tourner entre une première posture dans laquelle le verrou d'engrenage (14) est déplacé vers la position de mise en prise et une seconde posture dans laquelle le verrou d'engrenage (14) peut se déplacer vers la position de désengagement ; et une partie d'actionnement pour actionner la rotation de la came (15).
(JA) 車両用シート(1)は、シートバック(3)の下端部よりも上側部位を傾倒角度可変に支持するリクライニング部(10)を備え、リクライニング部(10)は、シート前後方向に揺動可能であり、揺動端部(22)にてシートバック3を支持しているリンク(12)と、リンク(12)の揺動軸(C)を中心に円弧状に配列された複数の歯(25)を有し、リンク(12)と一体に回動されるギヤ(13)と、ギヤ(13)に噛み合う係合位置と、ギヤとの噛み合いから解放される非係合位置との間でスライド可能なギヤロック(14)と、ギヤロック(14)を係合位置に移動させる第1姿勢とギヤロック(14)の非係合位置への移動を許容する第2姿勢との間で回動可能なカム(15)と、カム(15)の回動を操作する操作部と、を有する。
