クツシヨン１６が取付けられている。 The frame body 1 includes boss portions 11, 1 which are arranged at intervals in the lateral direction and are erected on the bottom portion 2 in pairs on the left and right sides.
1. The spring member 12 is formed by bending a rod-shaped spring material into a U-shape, for example, and is inserted into the locking holes 11a, 11a formed in the boss portions 11, 11, thereby forming a frame. It is supported by body 1. Further, the intermediate portion 14 of the spring member 12 is slidably pressed against the back portions of the legs 7, 7 of the headrest 5. Recesses 15 that can be releasably engaged with the intermediate portion 14 of the spring member 12 are formed in the leg portions 7, 7 at intervals in the axial direction. If necessary, the intermediate portion 14 of the spring member 12
may be pressed against the front side of the leg portion 7, or may be pressed against both the front side and the back side. Alternatively, the spring member 12 may be pressed against the side surface of the leg portion 7, and in this case, a spring member may be provided for each leg portion. Note that an appropriate cushion 16 is attached to the frame 1.

る。 According to the above structure, the support part 9 is integrally molded at the same time as the frame body 1 is molded, and at that time, the through holes 8, 1
0 can be molded simultaneously. Therefore, since it is only necessary to form the spring member 12, the number of parts machining steps required to construct the headrest support device is extremely small. Further, the leg portions 7 are inserted into the through holes 8 and 10, and both arm portions 13 and 13 of the spring member 12 are inserted into the locking holes 11a and 11.
Since it only needs to be locked to a, there is no need for welding or the like, and the number of man-hours required for assembly is extremely small. Therefore, the energy consumption required for component processing and assembly is also significantly reduced. In use, the spring member 12 is in the recess 15 of the leg 7.
so that it engages with one of the two. By doing this, even if a downward force is applied to the headrest 1 due to its own weight or vibrations acting on it, the headrest 5 will be prevented from moving downward.
It is held in the set position. In addition, when changing the position of the headrest 5, the main body 6 is pushed downward by hand or the like against the elastic force of the spring member 12, or pushed upward, so that the spring member 12 moves into the other recess 15.
In this way, the headrest 5 can be positioned in stages.

めすることができる。 In addition, instead of forming the spring member 12 from a rod-shaped spring material as described above, it may be formed from a band-shaped spring material, for example, and in this case, the third
As illustrated in the figure, it is preferable to form the cross section into an arcuate shape so that the side that makes sliding contact with the leg portion 7 is a protruding surface. Further, the boss portion 11, locking hole 11a, etc. for locking the spring member 12 may be provided in the wall portion 3 instead of the bottom portion 2. Furthermore, the concave portion 15 of the leg portion 7 is omitted, and the spring member 12 and the leg portion 7 are omitted.
The headrest 5 may be brought into sliding contact with frictional resistance, thereby making it possible to position the headrest 5 steplessly.

がある。 As described above, the present invention forms a backrest frame body by integrally molding a wall part and a support part having through holes into which the legs of a headrest are loosely inserted, and the legs are supported by this frame body. Since the head rest is positioned by a spring member that is slidably pressed against the frame, it is only necessary to form the spring member in addition to the frame, and the number of parts is small, so the number of man-hours for machining the parts is also small. Moreover, since it is simple and easy to assemble, it requires less assembly man-hours and has the effect of significantly reducing energy consumption.
