In this embodiment, the pillar brace groove 6 includes a first brace surface 601 on the pillar brace 2 and a second brace surface 602 on the mounting bracket 1.

All be provided with third smooth portion 603 on first clamp face 601 and the second clamp face 602, third smooth portion 603 is used for increasing the axial frictional force of seat headrest pillar and first clamp face 601, the second clamp face 602, and the difficult axial of back aversion is established to seat headrest pillar clamp to the pillar clamp groove 6 and is fixed, experiences and feels good.

Further, third prevention of skidding portion 603 is for being the anti-skidding line that the wave set up, and the trough portion of low concavity can be used for holding the seat headrest pillar on the third prevention of skidding portion 603, and bellied ridge makes the axial frictional force of car headrest pillar and first clamp face 601, second clamp face 602 bigger on the third prevention of skidding portion 603, and the difficult axial displacement after the support presss from both sides to establish fixedly to the seat headrest pillar, experiences and feels better.

The first connecting mechanism 7 comprises an adjusting screw 701 and a knob nut 702, wherein the adjusting screw 701 is arranged on the same side of the pillar splint 2 as the first clamping surface 601 or on the same side of the installation frame body 1 as the second clamping surface 602: when the adjusting screw 701 is arranged on the pillar splint 2, a fixing hole 703 matched with the adjusting screw 701 penetrates through the installation frame body 1, after the pillar splint 2 is in limit connection with the installation frame body 1, one end of the adjusting screw 701, which is far away from the pillar splint 2, penetrates through the fixing hole 703 and then is fixed with the knob nut 702 in a threaded manner; when adjusting screw 701 sets up on installation support body 1, run through on the pillar splint 2 have with adjusting screw 701 complex fixed orifices 703, the pillar splint 2 with install the spacing hookup back of support body 1, the one end of keeping away from installation support body 1 on adjusting screw 701 passes behind the fixed orifices 703 and the knob nut 702 spiro union is fixed. The seat headrest pillar is fixed by the knob nut 702 and the adjusting screw 701, so that the pillar clamp plate 2 and the installation frame body 1 fix the seat headrest pillar together. Only need lift off knob nut 702 during the dismantlement can make pillar splint 2 can take off from the installation support body 1, easy dismounting, and it is more convenient when using knob nut 702 and adjusting screw 701 fixed mode to make the width of adjusting pillar clamp groove 6.

In this embodiment, the width section of the first positioning rail 903 and the width section of the slide bar 901 are combined to form an octagonal plane in a Chinese character 'ao' shape. The anti-slip assembly 904 comprises a first anti-slip part 9041 and a second anti-slip part 9042, the first anti-slip part 9041 is fixed to a position corresponding to the concave part of the octagonal plane, the second anti-slip part 9042 is fixed to a position, corresponding to the first anti-slip part 9041, of the sliding sleeve 902, and the first anti-slip part 9041 is matched with the second anti-slip part 9042 in an abutting mode. The first slip prevention part 9041 and the second slip prevention part 9042 are more stably engaged with each other.

Further, the first anti-slip portions 9041 are anti-slip lines arranged in a wave shape, and the second anti-slip portions 9042 are anti-slip lines arranged in a wave shape. The recessed valley of the first anti-slip part 9041 can be used for accommodating the ridge of the second anti-slip part 9042, the recessed valley of the second anti-slip part 9042 can be used for accommodating the ridge of the first anti-slip part 9041, when a user leans against the side headrest 4, the side headrest 4 has a tendency of turning outwards, so that the ridge of the second anti-slip part 9042 is clamped into the valley of the first anti-slip part 9041, and the ridge of the first anti-slip part 9041 is clamped into the valley of the second anti-slip part 9042, so that the sliding resistance of the sliding sleeve 902 on the sliding rod 901 is larger, the sliding sleeve 902 is not easy to slide on the sliding rod 901, and the supporting effect is better.

In this embodiment, a third positioning rail 813 protruding outward and/or inward is disposed on the column sleeve 802 along the length direction of the column sleeve 802, so as to limit the rotation of the first sliding member 803 and the second sliding member 804 on the column sleeve 802.

Further, the width section of the third positioning rail 813 and the width section of the column sleeve 802 form a regular polygonal plane in combination; the communicating grooves 805 are formed at the positions corresponding to the corners of the regular polygonal plane, so that the column sleeve 802 can be designed to be thinner, and the communicating grooves 805 are formed at the positions corresponding to the corners of the regular polygonal plane, so that the first sliding member 803, the second sliding member 804 and the column sleeve 802 can be stably connected when the column sleeve is locked.

In this embodiment, the lock member 806 is a ball, the lock member 806 is moved in the radial direction of the column jacket 802 in the communication groove 805 to be restricted, the opening of the communication groove 805 is constricted by caulking, and the lock member 806 is not separated from the communication groove 805 when moving. When the position of the headrest 3 is adjusted, the second slider 804 or the headrest 3 is pushed after the locking protrusion 807 moves away from the communication groove 805, the spherical surface of the lock member 806 tends to move in the direction of the first slider 803 when abutted by the locking recess 808, and the spherical surface of the lock member 806 gradually moves out of the locking recess 808 as the sliding distance of the second slider 804 on the column cover 802 increases, and the lock member 806 does not lock the second slider 804 when the second slider 804 slides on the column cover 802. The locking member 806 takes up less space and the adjustment process is smooth and non-jamming.
