配置された。DESCRIPTION OF A SPECIFIC EXAMPLE The synchronizing mechanism used for both seat and back lock devices of this invention will be explained below based on a specific example shown in the drawings. A specific example 10 of the synchronizing mechanism used in both the seat and back locking devices of this invention is shown, and this synchronizing mechanism 1
0, a pair of shafts 11, 12 are supported correspondingly to the locks 31, 32 of both locking devices 30 arranged on either side of the seat, and a connecting rod 13 is attached to the flange of one of the shafts 11. One end is screwed to one of the shafts 11 at an appropriate distance from the flange 15 of the other shaft 12, and the other end is screwed to the other shaft 12 at an appropriate distance from the flange 16 of the other shaft 12. It is movable and connected to prevent rotation, and further,
The compression spring 14 is connected to the other shaft 12
flange 16 and the other end of the connecting rod 13.
特に、そのシヤフト１１は、ねじ切りされた穴
１７を形成し、そのシヤフト１２は角シヤフトに
製作され、そして、その連結ロツド１３は、両端
に座金１８，１９を溶接したパイプで製作され、
一端側に穴２０を明けてある。 In particular, the shaft 11 forms a threaded hole 17, the shaft 12 is made of a square shaft, and the connecting rod 13 is made of a pipe with washers 18, 19 welded to each end;
A hole 20 is made at one end.
また、この同期機構１０において、２１は穴、
そして、２２は角穴である。 Further, in this synchronization mechanism 10, 21 is a hole;
And 22 is a square hole.
したがつて、その両ロツク装置３０において、
その連結ロツド１３の一端がビス２３をその穴２
０に通してそのねじ切りされた穴１７にねじ込ま
れ、そのシヤフト１１に連結されて、その一端と
そのシヤフト１１との遊びを省き、一方、それと
他端がその角穴２２をそのシヤフト１２に嵌め合
わせて連結されてその他端とそのシヤフト１２と
の遊びをその圧縮スプリング１４で防いであるの
で、操作レバー（図示せず）の動きが、ラツチ
（図示せず）に伝達されると、その動きは、その
圧縮スプリング１４の作用下で、その連結ロツド
１３によつてその一方のシヤフト１１からその他
方のシヤフト１２に同期的に伝達され、その両ロ
ツク装置にロツク動作させる。 Therefore, in both locking devices 30,
One end of the connecting rod 13 inserts the screw 23 into the hole 2.
0 through its threaded hole 17 and connected to its shaft 11 to eliminate play between its one end and its shaft 11, while its and the other end fit through its square hole 22 into its shaft 12. The compression spring 14 prevents play between the other end and its shaft 12, so that when the movement of the operating lever (not shown) is transmitted to the latch (not shown), the movement is transmitted synchronously from one shaft 11 to the other shaft 12 by means of its connecting rod 13 under the action of its compression spring 14, causing a locking action on both locking devices.
また、連結ロツド１３がその一端とそのシヤフ
ト１１のフランジ１５との間に隙間を置いてある
ので、その連結ロツド１３は、そのシヤフト１
１，１２間に容易に組み付けられる。 Also, since there is a gap between one end of the connecting rod 13 and the flange 15 of the shaft 11, the connecting rod 13
It can be easily assembled between 1 and 12.
考案の利便・利益
この考案によれば、連結ロツドが一対のシヤフ
トの一方にねじ止めされるので、遊び連結される
箇所が少なくなり、シート・バツクの両ロツク装
置が操作される際、連結箇所の遊びによる異音の
発生が未然に防止され、実用的になる。Convenience/Benefits of the invention According to this invention, since the connecting rod is screwed to one of the pair of shafts, the number of loosely connected parts is reduced, and when both the seat and back locking devices are operated, This prevents the occurrence of abnormal noise due to play, making it more practical.
