  • Publication number: 20170144573
    Abstract: A headrest moving device, wherein a lever member, which is connected to the seat or the headrest in a pivoted state, presses the pawl, thereby releasing the engagement between the pawl and the ratchet. A consumer can release the locking at any position by operating a lever member externally protruded from the headrest after the consumer has moved the headrest. The method of releasing the locking can be easily recognized by the consumer, therefore the consumer can effectively and easily utilize the headrest moving device.

  • Patent number: 9499078
    Abstract: Provided is a headrest moving device. When first and second gears, each of which has numerous teeth formed in widthwise and lengthwise directions, are engaged, the numerous widthwise teeth are engaged, and the numerous lengthwise teeth are engaged. Due to the teeth, it is possible to minutely adjust a position of a headrest and to withstand a high load. Even when some of the teeth are disengaged, the headrest moving device can be operated and provides excellent durability.

  • Publication number: 20150366353
    Abstract: Provided is a headrest folding apparatus. An oblique face is formed on a support for supporting a headrest. When the headrest is in an upright position, the oblique face comes into contact with a first member. The headrest folding apparatus prevents a loose gap from occurring in an upright state, simplifies components to be made compact, and allows a seat to be easily assembled and a manufacturing cost to be cut down.
