Abstract

A headrest that is versatile, in which operation load in tiling of the headrest from a head support position to a stowed position is reduced for easy headrest tilting operation and in which noise or abnormal sound caused by the headrest is prevented, and a vehicle seat with such a headrest. [MEANS FOR SOLVING PROBLEMS] The headrest can be set to a head support position where the headrest is erected relative to the backrest and to a stowage position where the headrest is tilted from the head support position. The head rest includes a pillar (1) having a lateral shaft section (12) and mounted on the upper part of the backrest (S2), a headrest frame (2) pivotally engaged with the lateral shaft section (12) of the pillar (1), headrest frame urging means (3) for urging the headrest frame (2) to one side, lock means (4) capable of preventing relative pivoting between the headrest frame (2) and the pillar (1), a ratchet lever (44) for operating the lock means and sliding laterally, and ratchet lever urging means (45) for urging the ratchet lever (44). The ratchet lever urging means (45) urges the ratchet lever (44), which slides laterally, at a predetermined angle.

Description

technical field [0001] The present invention relates to a headrest and a vehicle seat including the headrest, in particular to a headrest that can stand upright relative to the back seat and a headrest that can be tilted from the headrest to a stowed state and the headrest including the headrest. Pillow car seats. Background technique [0002] Generally, a headrest for protecting a passenger's head is mounted on an upper portion of a back seat of a vehicle seat. And, now, the lower part of the headrest pillar is installed on the crossbar in the left and right direction in the back seat so that it can freely rotate back and forth. The technique of putting it away is known (see Patent Document 1). [0003] In addition, a technique has been proposed that includes a pillar having a horizontal shaft portion and is attached to the upper portion of the seat back, a headrest main body whose lower side is rotatably provided on the horizontal shaft portion of the pillar, and a headr...
