The elasticity is 3, and the top end of the (10) miscellaneous sheet 3 forms a stop. The face 31 is formed with a descending face 32 downwardly from the top end of the stop face 31, and the stop face 31 of the positive pressure piece 3 functions as an elastic floating sink. Further, please refer to the third and fourth figures, that is, when the headrest 2 is inserted into the sliding groove 11, the positioning surface of the headrest 2 is forced to the falling surface of the elastic pressing piece 3, so that the stopping surface 31 T Shen (four) financial position component 12 is also unique, so if you want to pull the headrest 2 up so that the insertion part U exits the sliding groove u, the elastic piece 3 collision = 31 happens to be affected by the daring component 12 Stop riding and riding on ^ even to book _ stuck 'to make the headrest; ^ will occur as a phenomenon of the ship. 3 M409765 々 However, the above-mentioned headrest is simple and convenient to use, but usually the width of the headrest is narrow. The user may touch the hard frame of the headrest because the left and right sides of the head turn. In addition to the discomfort, there is a considerable gap between the headrest and the back of the chair, so that the neck of the user is suspended, which causes a problem of shoulder and neck pain when used for a long time. [New content] 'The edge is' in order to improve the discomfort of the above-mentioned conventional chair headrest when leaning against it. The present invention provides a kind of support between the upper end of the seat back and the supporting seat back. U-shaped curved headrest 'and the rear end of the headrest can be raised and lowered, so that the height of the headrest can be adjusted, so that the user's head and neck can be comfortably supported and supported at the same time. The solution solution adopted by the present invention is provided with an inverted U-shaped front and rear ends of the headrest which can be flexibly bent at will, respectively, which are respectively connected between the upper end of a seat back and a seat back support unit. And the rear end of the headrest is fixed on the adjustable positioning unit which is slidable and positioned at the upper end of the backrest unit of the chair. According to the above scheme, the headrest includes a flexible core plate, and the outer side of the core plate is covered with a soft pillow body. According to the above solution, the adjusting and positioning unit comprises a sliding seat which can be fixed at the rear end of the headrest and is provided with a fit, so that the sliding rod provided on the firing unit can be worn, and the rear side of the sliding seat Opening a chamber with a narrow outer width and communicating with the two slides, and "two opposite clamping blocks are placed in the chamber so that the outer ends of the two positioning blocks can resist the cup" while at the same time Between the two - forcing the block, and between the two sides of the pressing block and the positioning block on the side of the two sides, there is a slanting abutting surface, and the pivoting at the outdoor side of the sliding block corresponds to The rear end of the pressing block has a positioning wrench capable of pushing against or retracting from the pressing portion and the releasing portion on the pressing block. Therefore, by the lifting adjustment of the above-described new type of slide, the inverted U-shaped 4 bends can be made. When the rear end of the pillow is moved up and down, the height of the pillow can be changed to make the month b. ^Senior relies on the requirements of ploughing, and the pillow can withstand the abutment surface = but more comfortable than the m" and the upper end of the chair back and the headrest will not be mixed due to the adjustment of the question, and then let the user Wei The ministry can also be supported without being suspended. The present invention can be fully understood by the following embodiments and with reference to the accompanying drawings, and is implemented according to the following: [Embodiment] «Monthly, as shown in the fifth figure, the present invention includes a back of a seat back 1. A seat back support unit 4' having a branch t and a headrest 2 capable of elastically bending an inverted 1 shape between the upper side of the shot i and the shot area unit 4, wherein the seat back supports early 4 The upper end is provided with two opposite sliding bars. The second contact bar 2 includes a core plate 23 which can be flexibly bent, and the outer side of the core plate 23 is covered with an elastic and soft pillow body 24, so that the headrest 2 It can be in a state of being inverted, and its front end 25 can be clearly defined at the upper end of the seat back, and the rear end thereof can be coupled to an adjustment positioning unit 5. The other adjustment positioning device 5 as described in the sixth, seventh and eighth and ninth figures includes: a slider whose upper end is engaged at the rear end 26 of the headrest 2, and the "seat seat 51 _La again There are two slides for the two sliding rods 41 to be worn, and the rear contact of the sliding block 51 is narrow and wide inside, and the capacitance with the two slides is 512; And the positioning block % can be loaded into the chamber 512, the outer ends of the two positioning blocks 52 can interfere with the corresponding sliding _, and the two positioning blocks help the _ end with a set of Wei Wei cut, and then Re-establishing - forcing 53 to install the ridge money 52 (10), the two sides of the squeezing block 53 are also provided with a slanting abutment surface 53 corresponding to the slanting abutment surface 521 of the positioning block 52 of each corresponding end, and then in the sliding seat The outer port of the chamber 512 of the 51 is fixed at a position, and the positioning wrench 54 is slid under the squatting of the shackle 54 and the pressing portion (4) and the releasing portion 542 are respectively disposed at the rear end of the granule wrench 54 corresponding to the cymbal 53. After the 54 is turned down, 'as shown in the tenth figure' can be produced by the compression part 541 ^ ^ 53 or as the tenth - figure Qing, in the positioning plate people are good / pull the general 'Wei 541 retreat The lion is in the block 53, and A gap is formed between the second 542 and the forced squeeze block 53 so that the forced block is illusively shifted back. Therefore, please refer to the twelfth figure, the inverted _, formed - wide and soft and comfortable for the user = outside, but also through the adjustment positioning unit 5 at the rear end of the headrest 2 = ^ is turned up (as shown in the thirteenth figure), so that the slider 51 can slide on the back of the seat back, the mast 41, so that the rear end of the headrest 2 can be followed by the headrest 2 The top of the head is extended or descended, that is, the difference between the back and the headrest 2 of the south end of the front end of the _2 ^人=The neck will not have the feeling of being uncomfortable, and at the same time, you can get the appropriate ones to rely on the above.
