Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a stay mounting structure for a cantilevered headrest in a vehicle seat in which the headrest is supported by a seatback in a cantilevered manner.

[0002]

[Prior Art]

 Some conventional vehicle seats have a headrest 1 supported by a stay 2 on a seat back SB in a cantilevered manner, as shown in FIGS. In this, a bracket 4 is welded to the top of the back frame 3 of the seat back SB, and the upper and lower parts of the stay 2 integrated with the headrest 1 are fastened and fixed to the bracket 4 with bolts 5 and 5. The bracket 4 includes a side surface portion 41 that extends along the side surface of the seat back SB, a front surface portion 42 that is bent from the front end of the side surface portion 41 along the backrest surface of the seat back SB, and a rear end portion of the side surface portion 41 that extends from the seat back SB. And a rear surface portion 43 that is bent along the rear surface of the, and has a U-shaped cross section. The front surface 42 and the rear surface 43 of the bracket 4 are provided with insertion holes 44, 44 above and below which the screw parts 51, 51 of the bolts 5, 5 are inserted. The insertion holes 44, 44 of the bracket 4 are inserted into the stay 2 between the front surface portion 42 and the rear surface portion 43 of the bracket 4, and the bolts 5, 5 are inserted into the holes 21, 21 formed above and below the stay 2. It is formed at a position overlapping the holes 21, 21 of the stay 2 so that the screw parts 51, 51 are inserted.

[0003]

[Problems to be solved by the device]

 Therefore, in order to fasten and fix the stay 2 of the headrest 1 to the bracket 4, the stay 2 is inserted into the bracket 4 from above, and the holes 21 and 21 of the stay 2 are inserted into the insertion holes 44 and 44 of the bracket 4. The stay 2 is moved upward and downward so as to overlap each other, the holes 21 and 21 of the stay 2 are aligned with the insertion holes 44 and 44 of the bracket 4, and the screw portions 51 and 51 of the bolts 5 and 5 are attached to the bracket 4. It was necessary to insert the nuts into the threaded portions 51 and 51 of the bolts 5 and 5 and to fasten the stay 2 to the bracket 4 with the bolts 5 and 5 to fix the stay 2 to the bracket 4. Therefore, in order to align the holes 21 of the stay 2 with the insertion holes 44 of the bracket 4, it is necessary to move the stay 2 as described above. There was a problem that it took time. The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to make it easy to perform an attaching operation for fixing a stay to a bracket.

[0004]

[Means for Solving the Problems]

 A stay mounting structure for a cantilevered headrest in a vehicle seat according to the present invention includes a positioning plate that is fixed to the stay along the inner surface of the bracket, and is locked to the upper end of the bracket on the plate. It is characterized by forming parts.

[0005]

[Action]

 When inserting the stay into the bracket, insert it until the locking part of the stay positioning plate is locked to the bracket, and the stay plate locks the locking part to the upper end of the bracket, Since it does not fall, the stay can be easily aligned with the bracket simply by inserting it into the bracket.

[0006]

【Example】

 An embodiment according to the present invention will be described with reference to FIGS. 1 to 4. However, since the stay 2 is different from the conventional product, the stay 2 will be described, and the other parts are denoted by the same reference numerals and the description thereof is omitted. To do. Positioning plates 6, 6 are fixed to the lower portion of the stay 2.

The plate 6 has a plate-like shape, and holes 61, 61 are formed on the lower portion of the plate 6 so as to overlap the holes 21, 21 of the stay 2. The plate 6 is provided at a position where the stay 2 faces the front surface portion 42 and the rear surface portion 43 of the bracket 4 when the stay 2 is inserted into the bracket 4. The plate 6 is formed with a locking portion 62 bent at the upper portion thereof. The locking portion 62 is locked to the upper end portion 45 of the bracket 4 so that the holes 21 and 21 of the stay 2 overlap the insertion holes 44 and 44 of the bracket 4 when the stay 2 is inserted into the bracket 4. The locking portion 62 of the plate 6 is bent toward the bracket 4 and, as described above, locks on the upper end portion 45 of the bracket 4 to prevent the stay 2 from falling.

According to the above configuration, when the stay 2 is inserted into the bracket 4, the engaging portions 62, 62 formed on the plates 6, 6 of the stay 2 are attached to the front and rear surface portions 42, 43 of the bracket 4. The stays 2 are engaged with the insertion holes 44, 44 of the bracket 4 by being locked to the upper ends 45, 45. Therefore, it is not necessary to move the stay 2 up and down to align the bracket 4, and the stay 2 can be easily attached to the bracket 4. If the width of the plate 6 is set so as to abut against the side surface portion 41 of the bracket 4, the stay 2 is moved left and right, and the alignment with the bracket 4 becomes unnecessary.

[0009]

[Effect of the device]

 According to the present invention, when the stay is inserted into the bracket, the locking portion formed on the plate fixed to the stay locks the locking portion of the plate to the bracket, and the stay does not drop. The stay can be inserted in the bracket. Therefore, the work of aligning the stay in the bracket in the upward and downward directions is not required, and the mounting work for fastening and fixing the stay to the bracket can be easily performed.
