【従来の技術】[Prior Art]

従来のシートスライド装置としては、例えば図１１〜図１３に要部を示すよう なものがある。すなわち、座席側レール部材１に操作レバーの軸部２を軸受部材 ３で枢支し、軸部２は座席側レール部材１に沿って延びていて、軸部２に操作用 の回動動作部材であるラッチ部材４を固着してある。そして、この従来例では、 ラッチ部材４に軸部２を位置決めして嵌合させる凹溝５が形成してあり、凹溝５ に軸部４を嵌合させてからアーク溶接６によりラッチ部材４を軸部２に固着して ある。 As a conventional seat slide device, for example, there is a seat slide device shown in FIG. 11 to FIG. That is, the shaft portion 2 of the operation lever is pivotally supported on the seat side rail member 1 by the bearing member 3, the shaft portion 2 extends along the seat side rail member 1, and the shaft portion 2 has a rotational movement member for operation. The latch member 4 is fixed. In this conventional example, a recessed groove 5 for positioning and fitting the shaft portion 2 in the latch member 4 is formed. After the shaft portion 4 is fitted in the recessed groove 5, the latch member 4 is formed by arc welding 6. Is fixed to the shaft portion 2.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、このような従来のシートスライド装置では、前者にあっては、 作業性が悪く管理しにくいアーク溶接の工程が必要であるため作業時間が増えて 製造原価が嵩むという問題点があった。また、後者にあっては、操作レバーの軸 部を異形孔に合うよう加工したり、環状溝を切削加工しなければならないので、 加工工程が多く、やはり製造原価が嵩むという問題点があった。 However, such a conventional seat slide device has a problem in that the former requires an arc welding process that is poor in workability and difficult to control, and thus increases the working time and increases the manufacturing cost. In the latter case, the shaft of the operating lever must be machined to fit the deformed hole and the annular groove must be machined, so there are many machining processes and the manufacturing cost is high. ..

Has been.

【００１６】 回動動作部材たるラッチ部材６０は操作レバー５０の軸部５１に固着するため の特別な構成を有している。すなわち、ラッチ部材６０の基部には操作レバー５ ０の軸部５１が嵌合する溝部６１が形成され、溝部６１の底に軸部５１に沿い突 起溶接による溶着用の突起部６２，６２が背面からプレス成形したエンボスとし て突設されており、突起部６２，６２の頂部は軸部５１が安定して当接する平面 状に形成されている。突起部６２，６２の近傍で隣接する溝部６１の底面は、保 持面６３をなし、溶着時に突起部６２，６２が溶融して軸部５１が突起部６２， ６２にめり込んだとき軸部５１が当接するようになっている。The latch member 60, which is a rotary motion member, has a special structure for fixing to the shaft portion 51 of the operation lever 50. That is, a groove portion 61 into which the shaft portion 51 of the operation lever 50 is fitted is formed at the base of the latch member 60, and projection portions 62 and 62 for welding by protrusion welding are formed along the shaft portion 51 at the bottom of the groove portion 61. It is projected from the back surface as an emboss which is press-molded, and the tops of the projections 62, 62 are formed in a plane shape with which the shaft 51 is in stable contact. The bottom surfaces of the groove portions 61 adjacent to each other in the vicinity of the protruding portions 62, 62 form a holding surface 63, and when the protruding portions 62, 62 are melted during welding and the shaft portion 51 is fitted into the protruding portions 62, 62, the shaft portion 51. Are in contact with each other.

【００１７】 操作レバー５０の軸部５１には回動動作部材として前記伝達部材５３が固着さ れている。伝達部材５３は平行に配設されている隣りのスライドレール１０のラ ッチ部材６０を連動させるケーブル（図示省略）が連結されるものである。The transmission member 53 is fixed to the shaft portion 51 of the operation lever 50 as a rotary motion member. The transmission member 53 is connected to a cable (not shown) for interlocking the latch members 60 of the adjacent slide rails 10 arranged in parallel.

【００１８】 操作レバー５０の軸部５１と枢支ブラケット４０との間には、ラッチ部材６０ の各係合突起６５が係止穴２１ａ，２１ａ，…に係合する方向に付勢する図示省 略した付勢ばねが張設されている。Between the shaft portion 51 of the operating lever 50 and the pivot bracket 40, each engagement projection 65 of the latch member 60 urges in the direction of engaging the locking holes 21a, 21a ,. An abbreviated biasing spring is stretched.

【００１９】 次に作用を説明する。 回動動作部材たるラッチ部材６０を操作レバー５０の軸部５１に固着する手順 は次のとおりである。Next, the operation will be described. The procedure for fixing the latch member 60, which is a rotary motion member, to the shaft portion 51 of the operation lever 50 is as follows.

【００２０】 図３（ａ）に示すように、先ず、ラッチ部材６０の溝部６１に嵌入するよう操 作レバー５０の軸部５１を挿入し、ラッチ部材６０の溶着用の突起部６２，６２ の頂部に操作レバー５０の軸部５１を当接させ、さらに圧接する。ラッチ部材６ ０の突起部６２，６２は操作レバー５０の軸部５１に沿っていて頂部が平面状で あるので、軸部５１は、ずれないよう突起部６２，６２に当接し、軸部５１は安 定して位置決め保持される。As shown in FIG. 3A, first, the shaft portion 51 of the operating lever 50 is inserted so as to be fitted in the groove portion 61 of the latch member 60, and the protrusions 62, 62 of the welding of the latch member 60 are inserted. The shaft portion 51 of the operation lever 50 is brought into contact with the top portion, and further pressure-welded. Since the projections 62, 62 of the latch member 60 are along the shaft 51 of the operating lever 50 and have a flat top, the shaft 51 abuts the projections 62, 62 so as not to be displaced, and the shaft 51 Is stably positioned and held.

【００２１】 そこで、操作レバー５０の軸部５１とラッチ部材６０との間に電流を流すと、 電流が集中する突起部６２，６２が溶融して軸部５１が突起部６２，６２にめり 込み、軸部５１も溶融して突起部６２，６２に溶着する。突起部６２，６２が溶 融してめり込んだとき、突起部６２，６２が当接していない部位で軸部５１がラ ッチ部材６０の溝部６１の底である保持面６３に当接するのでそこで軸部５１が 止まり、操作レバー５０の軸部５１とラッチ部材６０の基部との相対位置関係が 定まり、図３（ｂ）に示すようにラッチ部材６０は精度よく操作レバー５０の軸 部５１に溶接固着される。Therefore, when an electric current is passed between the shaft portion 51 of the operating lever 50 and the latch member 60, the protrusions 62, 62 on which the current concentrates are melted and the shaft portion 51 slips over the protrusions 62, 62. Then, the shaft portion 51 is also melted and welded to the protrusions 62, 62. When the protrusions 62, 62 melt and sink into each other, the shaft 51 abuts on the holding surface 63 which is the bottom of the groove 61 of the latch member 60 at a portion where the protrusions 62, 62 do not abut. The shaft portion 51 stops, the relative positional relationship between the shaft portion 51 of the operation lever 50 and the base portion of the latch member 60 is determined, and as shown in FIG. 3B, the latch member 60 is accurately attached to the shaft portion 51 of the operation lever 50. It is fixed by welding.

【００２２】 このようにして固着されたラッチ部材６０を有するシートスライド装置は、座 席が停止しているときは、ラッチ部材６０の先端の係合突起６５が係止ブラケッ ト２１の係止穴２１ａ，２１ａ，…のいずれかに係合していて、車体側レール部 材２０と座席側レール部材３０とは滑動不能に拘束されている。In the seat slide device having the latch member 60 fixed in this way, when the seat is stopped, the engaging projection 65 at the tip of the latch member 60 is engaged with the engaging hole of the engaging bracket 21. 21a, 21a, ..., And the vehicle body side rail member 20 and the seat side rail member 30 are non-slipably restrained.

The fitting protrusion 65 is disengaged from the locking holes 21a, 21a, ... Of the locking bracket 21 on the vehicle body side rail member 20 side. In addition, the transmission member 53, which is a rotating member, also rotates, and the latch members 60 of the adjacent slide rails 10 arranged in parallel are interlocked with each other via a cable (not shown) to move the adjacent slide rails. The restraint in 10 is also released.

In the third embodiment, in the first and second embodiments, the protrusions are provided as small protrusions at both ends of the base of the latch member, respectively, whereas the protrusions continuous along the shaft portion 51 of the operation lever 50 are provided. The latch member 60b is provided with the portion 62b. The surface of the base portion of the latch member 60 outside the protruding portion 62b forms a holding surface 63b, and the top surface of the protruding portion 62b is formed to have a width that intersects the shaft portion 51 of the operating lever 50.

The shaft 51 is brought into contact with the shaft 51, and the shaft 51 is stably positioned and held. When the shaft 51 is inserted into the protrusion 62b during welding, the shaft 51 is not contacted with the shaft 51 at the surface of the base of the latch member 60. Since it abuts against a certain holding surface 63b, the relative positional relationship is determined, and the latch member 60b is welded and fixed to the shaft portion 51 of the operating lever 50 with high accuracy.

The protrusions 62c, 62c of the operating lever 50 are along the shaft portion 51 of the operating lever 50, and the apex is flat so that the shaft portion 51 can come into stable contact. The shaft portion 51 is brought into contact with 62c and 62c, and the shaft portion 51 is stably positioned and held.

【００３２】 溶接用の電流を流すと、電流が集中する突起部６２ｃ，６２ｃが溶融して軸部 ５１が突起部６２ｃ，６２ｃにめり込むと、突起部６２ｃ，６２ｃが当接してい ない部位で軸部５１がラッチ部材６０の基部の表面である保持面６３ｃに当接す るので操作レバー５０の軸部５１とラッチ部材６０ｃの基部との相対位置関係が 定まり、ラッチ部材６０ｃは精度よく操作レバー５０の軸部５１に溶接固着され る。When a welding current is applied, the protrusions 62c and 62c on which the current concentrates melts, and when the shaft 51 slips into the protrusions 62c and 62c, the shafts are not contacted with the protrusions 62c and 62c. Since the portion 51 abuts on the holding surface 63c that is the surface of the base of the latch member 60, the relative positional relationship between the shaft portion 51 of the operation lever 50 and the base of the latch member 60c is determined, and the latch member 60c is operated accurately. It is welded and fixed to the shaft portion 51 of 50.
