본 고안은 다기능의 헤드레스트 프레임에 관한 것으로서, 특히 자동차의 시이트 등받이 상부에 착설하여 머리를 받쳐주고 오디오 스피커가 달려 음성이나 음향을 들을 수 있는 헤드레스트 프레임에 있어서, 상기 헤드레스트 프레임에 상기 스피커나 공기청정기를 선택적으로 또는 동시에 부착할 수 있고, 이중의 완충장치로 탁월한 탄력을 갖는 다기능의 헤드레스트 프레임에 관한 것이다.The present invention relates to a multifunctional headrest frame, and particularly, a headrest frame which can be mounted on an upper seat back of an automobile to support a head and an audio speaker can be heard to hear a voice or sound. An air purifier can be attached selectively or simultaneously, and a multi-functional headrest frame having excellent elasticity with a double shock absorber.
종래의 헤드레스트 프레임은 평판상태의 양쪽지지판(170)(170')의 내측면으로 돌출된 파지부(300)를 형성하고, 지지판 하단 절곡단부(110)에는 괘지요부(120)를 형성한 것에 지지봉(20)(20')을 상기 괘지요부(120)에 끼운 다음 지지봉(20)(20')의 절곡단부(190)에 삽착고정한 연결구(140)를 상기 파지부(300) 사이에 맞추어 볼트(150')를 너트공(150)에 결합한 구조로 되어 있어서, 각도조절시에 심한 소음이 발생되고 본체의 내구성이 약하여 약간의 외부충격에도 절곡 또는 파손되기 쉬우며, 차량사고시에도 머리받이로서 단순히 충격 완충효과만 있을뿐 탁월한 탄력 발휘하지는 못하는 문제점이 있었고, 이와 같은 구조는 단순한 머리받이 역할 외에는 다른 용도로서 겸용이 불가능한 결점이 있으며, 헤드레스트 프레임 본체 내부에 스피커를 내장한 경우에도 본체의 내구성이나 완충작용의 증진 및 차량 내부의 공기정화를 위해 공기정화기를 부착 할수 있는 구조로는 부적절하였다.The conventional headrest frame forms a grip portion 300 protruding to the inner side surfaces of both support plates 170 and 170 'in a flat state, and a ruler portion 120 is formed at the lower end of the support plate 110. Insert the support rods 20 and 20 'into the hanging portion 120, and then fit the connector 140 secured to the bent ends 190 of the support rods 20 and 20' between the grip portions 300. Since the bolt 150 'is coupled to the nut hole 150, severe noise is generated when the angle is adjusted, and the durability of the main body is weak, so that it may be easily bent or broken even in the event of a slight external shock. There was a problem in that the shock absorbing effect was not merely excellent in exerting elasticity, and such a structure had a drawback in that it could not be used for any other purpose except a simple headrest, and even when the speaker was built in the headrest frame, It was not suitable to attach an air purifier to improve the performance of the castle or the buffer and to purify the air inside the vehicle.
본 고안은 상기와 같은 문제점을 해결하기 위한 것으로서, 본 고안의 헤드레스트 프레임은 스폰지 외피에 내장된 프레임 본체에 오디오 스피커나 공기정화기를 선택적으로 또는 동시에 연결 장착하여 가까운 거리에서 카스테레오의 음향을 감상할 수 있을 뿐만 아니라 공기정화기에 의한 실내공기 정화효과를 기할 수 있고, 프레임본체를 단일판으로 하여 하부를 절곡시키고 지지봉 삽입공에 탄성부재를 삽착한 구조로 함으로써, 프레임에 양쪽 지지봉의 장착이 용이하고 헤드레스트가 충격에 의하여 요동할 때, 탄성부재에 의하여 탄력이 좋고, 소음을 최소화할 수 있는 특징이 있는 것으로서 이를 첨부도면에 따라 상세히 설명하면 다음과 같다.The present invention is to solve the problems as described above, the headrest frame of the present invention by selectively or at the same time connected to the frame body built in the sponge shell to enjoy the sound of the car stereo in close proximity In addition, it is possible to achieve the effect of purifying the indoor air by the air purifier.The structure of the frame body as a single plate is bent at the bottom and the elastic member is inserted into the support rod insertion hole. When the headrest is rocked by the impact, it is characterized by good elasticity by the elastic member, it can minimize the noise as described in detail according to the accompanying drawings as follows.

도면중 미설명부호 31은 헤드레스트 프레임 본체(1) 덮개용 스폰지이고, 32는 스폰지상의 스피커홀이다.In the figure, reference numeral 31 denotes a sponge for covering the headrest frame main body 1, and 32 denotes a sponge-shaped speaker hole.
이상과 같이 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above are as follows.
헤드레스트 프레임 본체(1) 상판(17)에 천공된 스피커홈(10)에 스피커(20)를 착설하여 카오디오와 연결시키면 방음과 진동작용이 우수할 뿐만 아니라, 프레임 본체(1)의 후면에 스피커(20)를 착설하여 유사기 프레임본체(1)의 하부절곡부(11)에 형성한 울림통겸 삽입장공(12)(12')과 절곡부(11)의 좌우측주면에 천설한 보조울림통(12a)(12a')에 의하여 스피커 소리를 관통시켜 주는 효과가 커서, 스피커의 음향효과를 더욱 높여주며, 공기정화기를 스피커홀(10)이나 흡입구(5) 부위 뒤에 장착하게 되면 외부에서는 보이지 않으면서 호흡기 가까운 곳에서 정화된 공기를 상기 울림통겸 삽입장공(12)(12')과 보조울림통(12a)(12a') 또는 흡입구(5) 등을 통하여 흡,배출하게 되므로 정화효과가 탁월한 장점이 있다.When the speaker 20 is installed in the speaker groove 10 perforated on the headrest frame body 1 upper plate 17 and connected to the car audio, the soundproofing and vibration action are excellent, and the rear surface of the frame body 1 Auxiliary receptacle installed on the left and right circumferential surfaces of the ring and insertion slot 12 and 12 'formed on the lower bent portion 11 of the similar frame body 1 by installing the speaker 20 ( 12a) (12a '), the effect of penetrating the sound of the speaker is large, further enhances the sound effect of the speaker, and if the air purifier is mounted behind the speaker hole 10 or the inlet port (5), without being visible from the outside The purified air in the vicinity of the respirator is absorbed and discharged through the ring and the insertion hole (12) (12 ') and the auxiliary ring (12a) (12a') or the inlet (5), so the purification effect is excellent. .
또한, 본체(1)의 하부에는 절곡부(11)를 형성하여, 평면으로된 프레임 본체(1) 상판(17)의 내구성이 강화되며 지지봉(2)(2')을 울림통 통풍구를 겸한 삽입장공(12)(12')에 끼우고 플라스틱 연결구(14)는 고정공(13)에 끼워 볼트공(15)(15a)과 볼트(15')에 의해 절곡 하단벽면(18)에 고정시키거나, 본체(1)의 절곡부(11)의 삽입장공(12)(12') 사이의 상기 고정공(13) 대신 개방된 수직연결벽면(18')에 볼트공(15)(15b) 및 볼트(15')에 의하여 고정이 용이하며 각도조절시에 소음이 발생되지 않고, 삽입장공(12)(12')에는 탄성부재(16)가 삽착되어 있어서, 유사시 본체(1) 상판(17)과 지지봉(2)(2') 사이를 완충시켜서 충격을 완화시키는 2중 충격완충 효과를 가지게 되는 것이다.In addition, the lower portion of the main body 1 is formed with a bent portion 11, the durability of the top plate 17 of the frame main body 1 in a flat surface is reinforced and the insertion hole which serves as a ring vent vent opening the support rods 2 (2 ') (12) (12 ') and the plastic connector 14 is fitted to the fixing hole 13 to be fixed to the lower wall surface 18 by the bolt holes (15) (15a) and the bolt (15'), Instead of the fixing hole 13 between the insertion hole 12, 12 ′ of the bent portion 11 of the main body 1, the bolt holes 15, 15b and the bolt ( 15 ') makes it easy to fix and noise is not generated during the angle adjustment, and the elastic member 16 is inserted into the insertion hole 12 and 12'. (2) (2 ') has a double shock buffer effect that cushions the shock to alleviate the impact.
이상과 같이 본 고안은 조립이 용이하고 내구성도 양호하며 높은 완충효과를 가짐은 물론 특히 스피커나 공기청정기 등을 정착할 수 있어 다양한 기능을 갖는 효과가 있다.As described above, the present invention is easy to assemble, has good durability, and has a high cushioning effect, and in particular, a speaker or an air purifier can be fixed, and thus has various effects.
