Abstract

The present invention relates to a headrest which can eliminate the shake to eliminate the uncomfortable feeling, and at the same time, the headrest not only can be changed to the use position and the retracted position, but also can be changed with the front-and-after angle at the use position to make the heat more comfortable. The headrest comprises the following components: a rotation restraint bracket which is formed with a contact part and a projecting step part; a stationary shaft which is reversely provided on the rotation restraint bracket; and a fastening board which has one end hinged on the substrate forming the base material of the headrest and is extended or compressed by a spring between the fastening board and the substrate. The headrest not only can reach two positions of a front limit position and a rear limit position in using, but also is provided with an operating handle on the substrate. Through the operation of the handle, the headrest can rotate frontwards to the retracted position when the fastening surface leaves a projected step part.

Description

technical field [0001] The present invention relates to a headrest mounted on a seat back constituting a seat of a vehicle, in particular to a headrest mounted on a passenger seat or a rear seat back. Background technique [0002] Considering the convenience of loading goods in the car, some vehicles can fold the seat. In this case, since the headrest sometimes gets in the way, it can be fully folded if it can be folded forward and stowed away. In addition, when there are no occupants, if the headrest is stowed away, the sight of the driver and the like will not be obstructed. Thereby, as shown in Patent Document 1 below, the headrest can be stowed in a state where it is folded to a stowed position close to the seat back. On the other hand, the shaking of the rotating part is a problem, but this shaking is caused by deformation or wear of the guide member or the position regulating member. If this problem occurs, the comfort of the head will be reduced and the seat occupan...
