Embodiment approach 1

[0064] Such as Figures 1 to 10 As shown, the headrest moving device according to an exemplary embodiment of the present invention is characterized in that it includes: a ratchet 200; a pawl 100, which engages with the ratchet 200; and a lever 10, which is used to press the ratchet 100 And the engagement between the ratchet 100 and the ratchet 200 is disengaged, wherein one of the ratchet 100 and the ratchet 200 is connected to the seat, and the other is connected to the headrest, and the lever A member 10 is pivotally connected to the seat or the headrest.

[0065] The pawl 100 is vertically disposed in the front-rear direction, and is formed in a plate-like shape, and a plurality of gear teeth 150 are formed on an upper portion thereof in width and length directions.

[0066] The pawl 100 is formed by coupling in the width direction a plurality of plates 100a formed with a plurality of gear teeth 240 in the length direction, and thus, a plurality of gear teeth 150 are forme...

Embodiment approach 2

[0117] Different from the above Embodiment 1, such as Figures 12 to 20 As shown, the headrest moving device according to the second exemplary embodiment further includes: a first connecting member 300 connected to the seat; a second connecting member 400 mounted on the first connecting member in a pivotal state; 300 on one side; the third link 500, which is installed in the other side of the first link 300 in a pivoted state; and the fourth link 600, one end of which is installed in a pivoted state In the second connecting part 400, the other end is pivotally installed in the third connecting part 500, wherein the headrest is connected to the fourth connecting part 600; the pawl 100' is connected to to the first link 300 ; and the ratchet 200 ′ is connected to the second link 400 .

[0118] For the same configuration as the above-described embodiment, detailed description and illustration are omitted.

[0119] A stopper protrusion 170 is protrudingly formed in the pawl 100'...

Abstract

The present invention relates to a headrest moving device, wherein a lever member, which is connected to the seat or the headrest in a pivoted state, presses the pole, thereby releasing the engagement between the pole 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. So, the way of releasing the locking can be easily recognized by the consumer, therefore the consumer can effectively and easily utilize the headrest moving device.

Description

technical field [0001] The present invention relates to a headrest moving device, and more particularly, to a headrest moving device in which, by pressing a pawl with a lever member connected to a seat or a headrest in a pivoted state, the pawl and the ratchet wheel The engagement between them is disengaged. Background technique [0002] According to the headrest moving device in the prior art, a headrest moving device having a tilting structure or a sliding structure has been proposed for arbitrarily adjusting the space between the headrest and the passenger rest area so that when the headrest is fixed to the seat back At the same time, the headrest is tilted at an angle by rotating the headrest about its fixed point. [0003] When using a sliding structure as proposed in Korean Patent No. 0790535, Korean Utility Patent Publication No. 2000-0015501, Korean Patent No. 0403478, Korean Patent Publication No. 2007-0105210 and US Patent Publication No. Or in the case of a head...
