Description

本発明は、シートをスライド可能に支持するシート用スライド装置に関する。   The present invention relates to a seat slide device that slidably supports a seat.

例えば、特許文献１に記載されたシート用スライド装置は、矩形波状に屈曲したロック部を可動側レールの長手方向と略直交する鉛直方向に変位させることにより、可動側レールが固定側レールに対してスライドすることを規制する規制状態と当該規制状態を解除する解除状態とを切り替える構成である。   For example, in the seat slide device described in Patent Document 1, the movable side rail is displaced from the fixed side rail by displacing the lock portion bent in a rectangular wave shape in the vertical direction substantially orthogonal to the longitudinal direction of the movable side rail. The switching state is switched between a restriction state for restricting sliding and a release state for releasing the restriction state.

ロック部は、当該ロック部を挟んで両側にそれぞれに設けられた一対の線状弾性変形部により支持されている。なお、特許文献１に係るロック部及び線状弾性変形部は、１本の線材に折り曲げ加工を施すことにより形成された一体成形品である。   The lock part is supported by a pair of linear elastic deformation parts provided on both sides of the lock part. In addition, the lock part and linear elastic deformation part which concern on patent document 1 are the integrally molded products formed by giving a bending process to one wire.

ロック部を挟んで一方側に設けられた一対の線状弾性変形部（以下、第１弾性変形部ともいう。）の先端側は、解除部材に係止されている。ロック部を挟んで他方側に設けられた一対の線状弾性変形部（以下、第２弾性変形部ともいう。）の先端側は、可動側レールに係止されている。   The distal end sides of a pair of linear elastic deformation portions (hereinafter also referred to as first elastic deformation portions) provided on one side across the lock portion are locked to a release member. The distal end sides of a pair of linear elastic deformation portions (hereinafter also referred to as second elastic deformation portions) provided on the other side across the lock portion are locked to the movable rail.

解除部材は、第１弾性変形部及び第２弾性変形部の変形状態を切り替えための部材である。つまり、解除部材が乗員等によって直接的又は間接的に操作されると、ロック部が規制状態又は解除状態となる。   The release member is a member for switching the deformation state of the first elastic deformation portion and the second elastic deformation portion. That is, when the release member is directly or indirectly operated by an occupant or the like, the lock portion is in a restricted state or a released state.

４．解除部材の構造等
解除部材９は、図１０に示すように、第１弾性変形部７Ｂ及び第２弾性変形部７Ｃの変形状態を切り替えるための部材である。以下、第１弾性変形部７Ｂ及び第２弾性変形部７Ｃを総称する際には、第１弾性変形部７Ｂ等と記す。 4). As shown in FIG. 10, the release member 9 is a member for switching the deformation state of the first elastic deformation portion 7B and the second elastic deformation portion 7C. Hereinafter, the first elastic deformation portion 7B and the second elastic deformation portion 7C are collectively referred to as the first elastic deformation portion 7B and the like.

すなわち、解除部材９は、第１弾性変形部７Ｂ側から可動側レール５の長手方向一端側（本実施形態では、車両前方側）に延びるレバー状の部材であって、開放断面部５Ｄ内のうち第１弾性変形部７Ｂと蓋壁部５Ｃとの間に配設されている。   That is, the release member 9 is a lever-like member that extends from the first elastically deformable portion 7B side to one end in the longitudinal direction of the movable rail 5 (in the present embodiment, the vehicle front side). Of these, it is disposed between the first elastic deformation portion 7B and the lid wall portion 5C.

解除部材９の長手方向一端側には、図１１に示すように、操作部１３が設けられている。操作部１３は、乗員により直接的又は間接的に操作されるハンドル部の一例であって、可動側レール５の長手方向一端（本実施形態では、前端）から突出した部位である。本実施形態では、操作部１３と解除部材９とは、閉断面形状を有する金属製の一体成形品である。   As shown in FIG. 11, an operation unit 13 is provided on one end side in the longitudinal direction of the release member 9. The operation unit 13 is an example of a handle unit that is directly or indirectly operated by an occupant, and is a portion that protrudes from one end in the longitudinal direction of the movable rail 5 (the front end in the present embodiment). In the present embodiment, the operation unit 13 and the release member 9 are metal integrally formed products having a closed cross-sectional shape.

解除部材９の長手方向他端側には押圧部９Ａが設けられている。押圧部９Ａは、蓋壁部５Ｃ側からロック部７Ａに接触する。そして、押圧部９Ａは、操作部１３に操作力が入力されると、当該操作力を利用してロック部７Ａを規制位置側から解除位置側に押圧する。   A pressing portion 9 </ b> A is provided on the other end side of the release member 9 in the longitudinal direction. The pressing portion 9A comes into contact with the lock portion 7A from the lid wall portion 5C side. Then, when an operation force is input to the operation unit 13, the pressing unit 9A uses the operation force to press the lock unit 7A from the restriction position side to the release position side.

解除部材９のうち押圧部９Ａと係止溝９Ｃとの中間位置には、図１０に示すように、蓋壁部５Ｃ側に突出した凸状の支点部９Ｂが設けられている。支点部９Ｂは、蓋壁部５Ｃのうち第１弾性変形部７Ｂ側の部位にて当該蓋壁部５Ｃに接触することにより、解除部材９の揺動中心点を構成する。   As shown in FIG. 10, a convex fulcrum portion 9B protruding toward the lid wall portion 5C is provided at an intermediate position between the pressing portion 9A and the locking groove 9C in the release member 9. The fulcrum portion 9B constitutes the pivot center point of the release member 9 by contacting the lid wall portion 5C at a portion of the lid wall portion 5C on the first elastic deformation portion 7B side.

つまり、解除部材９に操作力が入力されていない状態では（図１０の実線で示す状態）、押圧部９Ａは第１弾性変形部７Ｂ等から受ける弾性力により蓋壁部５Ｃ側、つまり鉛直方向上側に押圧されている。このため、解除部材９に操作力が入力されていない状態では、操作部１３側は鉛直方向下側に位置する。   That is, in a state where no operating force is input to the release member 9 (state indicated by a solid line in FIG. 10), the pressing portion 9A is on the lid wall portion 5C side, that is, in the vertical direction by the elastic force received from the first elastic deformation portion 7B and the like. It is pressed upward. For this reason, in the state where the operating force is not input to the release member 9, the operation unit 13 side is located on the lower side in the vertical direction.

操作部１３を鉛直方向上側に移動させる操作力が解除部材９に入力されると、支点部９Ｂを揺動中心として押圧部９Ａが鉛直方向下側に変位する（図１０の二点鎖線参照）。このため、ロック部７Ａが鉛直方向下方側に変位して解除位置となる。そして、上記操作力が消失すると、第１弾性変形部７Ｂ等の復元力により、ロック部７Ａが規制位置に復帰する。   When an operating force that moves the operating portion 13 upward in the vertical direction is input to the release member 9, the pressing portion 9A is displaced downward in the vertical direction with the fulcrum portion 9B as the center of oscillation (see the two-dot chain line in FIG. 10). . For this reason, the lock portion 7A is displaced downward in the vertical direction and becomes the release position. When the operation force disappears, the lock portion 7A returns to the restricted position by the restoring force of the first elastic deformation portion 7B and the like.

図１１に示す係止溝９Ｃは、第１係止部７４が係止される被係止部の一例である。係止溝９Ｃは、線状部７３の延び方向と略直交する方向に延びるとともに、蓋壁部５Ｃと反対側が開口した溝部である。つまり、本実施形態に係る係止溝９Ｃは、幅方向に延びるとともに、鉛直方向下側が開口した溝である。   The locking groove 9 </ b> C shown in FIG. 11 is an example of a locked portion where the first locking portion 74 is locked. The locking groove 9 </ b> C is a groove that extends in a direction substantially orthogonal to the extending direction of the linear portion 73 and is open on the opposite side to the lid wall portion 5 </ b> C. That is, the locking groove 9 </ b> C according to the present embodiment is a groove that extends in the width direction and is open on the lower side in the vertical direction.

係止溝９Ｃは、図１２に示すように、第１被係止面９Ｄ及び第２被係止面９Ｅを有して構成されている。第１被係止面９Ｄ及び第２被係止面９Ｅは、線状部７３の延び方向において互いに対向して係止溝９Ｃの側壁部を構成する。   As shown in FIG. 12, the locking groove 9 </ b> C has a first locked surface 9 </ b> D and a second locked surface 9 </ b> E. The first locked surface 9D and the second locked surface 9E are opposed to each other in the extending direction of the linear portion 73 to constitute the side wall portion of the locking groove 9C.

第１被係止面９Ｄは、延び方向一端側（本実施形態では、車両前方側）から第１係止部７４に接触可能な面である。第２被係止面９Ｅは、延び方方向他端側（本実施形態では、車両後方側）から第１係止部７４に接触可能な面である。   9D of 1st to-be-latched surfaces are surfaces which can contact the 1st latching | locking part 74 from the extending direction one end side (this embodiment vehicle front side). The second locked surface 9E is a surface that can contact the first locking portion 74 from the other end side in the extending direction (in the present embodiment, the vehicle rear side).

このため、第１係止部７４Ａ及び第２係止部７４Ｂは、第１被係止面９Ｄ及び第２被係止面９Ｅに接触可能な部位に位置する。なお、第１係止部７４Ａの先端及び第２係止部７４Ｂの先端それぞれは、係止溝９Ｃの延び方向中央に位置することが望ましい（図１３参照）。   For this reason, the first locking portion 74A and the second locking portion 74B are located at sites that can contact the first locked surface 9D and the second locked surface 9E. In addition, it is desirable that each of the leading end of the first locking portion 74A and the leading end of the second locking portion 74B is located at the center in the extending direction of the locking groove 9C (see FIG. 13).

つまり、第１係止部７４Ａが第１被係止面９Ｄ及び第２被係止面９Ｅと接触する長さ、並びに第２係止部７４Ｂが第１被係止面９Ｄ及び第２被係止面９Ｅと接触する長さが、共に係止溝９Ｃの延び方向長さの略１／２となることが望ましい。   That is, the length by which the first locking portion 74A contacts the first locked surface 9D and the second locked surface 9E, and the second locking portion 74B is the first locked surface 9D and the second locked surface. It is desirable that the length of contact with the stop surface 9E is approximately ½ of the length in the extending direction of the locking groove 9C.

なお、第１弾性変形部７Ｂの線状部７３に対して拘束力が作用しない自由状態においては、第１係止部７４Ａの先端と第２係止部７４Ｂの先端とは、互いに離間した状態となる。そこで、本実施形態では、一対の側壁部５Ａ、５Ｂが第１係止部７４の突出方向と略直交する壁面を構成する点を利用し、第１係止部７４の位置を規制している。   In the free state where the binding force does not act on the linear portion 73 of the first elastic deformation portion 7B, the tip end of the first locking portion 74A and the tip end of the second locking portion 74B are separated from each other. It becomes. Therefore, in the present embodiment, the position of the first locking portion 74 is regulated by utilizing the point that the pair of side wall portions 5A, 5B constitutes a wall surface that is substantially orthogonal to the protruding direction of the first locking portion 74. .

すなわち、ロックスプリング７及び解除部材９が可動側レール５に組み付けられた状態においては、図１３に示すように、一対の側壁部５Ａ、５Ｂそれぞれと第１線状部７３Ａ及び第２線状部７３Ｂとが接触する。このため、第１係止部７４Ａ及び第２係止部７４Ｂが第１被係止面９Ｄ及び第２被係止面９Ｅから離間する方向に変位することを規制される。   That is, in a state where the lock spring 7 and the release member 9 are assembled to the movable rail 5, as shown in FIG. 13, the pair of side wall portions 5A and 5B, the first linear portion 73A and the second linear portion, respectively. 73B comes into contact. For this reason, displacement of the first locking portion 74A and the second locking portion 74B in a direction away from the first locked surface 9D and the second locked surface 9E is restricted.

本実施形態では、図１２に示すように、解除部材９のうち係止溝９Ｃ部分の断面形状は閉断面形状である。このため、係止溝９Ｃの底部９Ｆ側、つまり第１被係止面９Ｄ及び第２被係止面９Ｅの鉛直方向上端側は、当該底部９Ｆにより閉塞された構成となっている。   In the present embodiment, as shown in FIG. 12, the cross-sectional shape of the locking groove 9C portion of the release member 9 is a closed cross-sectional shape. For this reason, the bottom 9F side of the locking groove 9C, that is, the vertical upper end side of the first locked surface 9D and the second locked surface 9E is closed by the bottom 9F.

解除部材９及び係止溝９Ｃ、つまり第１被係止面９Ｄ及び第２被係止面９Ｅと解除部材９とは、金属製の一体成形品である。なお、本実施形態では、角筒状のパイプ材に塑性加工を施すことにより、上記一体成形品を成形している。   The release member 9 and the locking groove 9C, that is, the first locked surface 9D, the second locked surface 9E, and the release member 9 are metal integrally formed products. In the present embodiment, the integrally molded product is formed by subjecting a square tube-shaped pipe material to plastic working.

そして、第１被係止面９Ｄ及び第２被係止面９Ｅそれぞれの高さ方向一端側（本実施形態では、下端側）には、第１被係止面９Ｄ及び第２被係止面９Ｅに対して傾斜した案内面９Ｇ、９Ｈが設けられている。   Then, the first locked surface 9D and the second locked surface are disposed on one end side in the height direction (the lower end side in the present embodiment) of each of the first locked surface 9D and the second locked surface 9E. Guide surfaces 9G and 9H inclined with respect to 9E are provided.

案内面９Ｇ、９Ｈは、高さ方向一端側（本実施形態では、下端側）に向かうほど、案内面９Ｇ、９Ｈ間の距離が拡大し、かつ、第１被係止面９Ｄ及び第２被係止面９Ｅに近づくほど案内面９Ｇ、９Ｈ間の距離が縮小するように傾斜している。   The distance between the guide surfaces 9G and 9H increases as the guide surfaces 9G and 9H move toward one end in the height direction (the lower end in the present embodiment), and the first locked surface 9D and the second locked surface The distance between the guide surfaces 9G and 9H is inclined so as to approach the locking surface 9E.

案内面９Ｇ、９Ｈは、係止溝９Ｃを形成する際の塑性加工時に、第１被係止面９Ｄ、第２被係止面９Ｅ及び底部９Ｆと共に成形された一体成形品である。そして、第１係止部７４と第１被係止面９Ｄ及び第２被係止面９Ｅとが接触する位置は、第１被係止面９Ｄ及び第２被係止面９Ｅの高さ方向一端と高さ方向他端との間の位置である。   The guide surfaces 9G and 9H are integrally molded products that are molded together with the first locked surface 9D, the second locked surface 9E, and the bottom portion 9F during plastic processing when the locking groove 9C is formed. And the position where the 1st latching | locking part 74, 1st to-be-latched surface 9D, and the 2nd to-be-latched surface 9E contact is the height direction of 1st to-be-latched surface 9D and the 2nd to-be-latched surface 9E. It is a position between one end and the other end in the height direction.

つまり、第１係止部７４は、係止溝９Ｃが設けられた部位において解除部材９の高さ方向一端（上端）と高さ方向他端（下端）との間に位置して第１被係止面９Ｄ及び第２被係止面９Ｅと接触する。   That is, the first locking portion 74 is located between the height direction one end (upper end) and the height direction other end (lower end) of the release member 9 at the portion where the locking groove 9C is provided. It contacts the locking surface 9D and the second locked surface 9E.

このため、第１係止部７４は、底部９Ｆと接触した状態で第１被係止面９Ｄと第２被係止面９Ｅとにより挟まれた状態となり、かつ、第１係止部７４と第１被係止面９Ｄ及び第２被係止面９Ｅとが接触する位置は、案内面９Ｇ、９Ｈと底部９Ｆとの間に位置する。   For this reason, the 1st latching | locking part 74 will be in the state pinched | interposed by the 1st to-be-latched surface 9D and the 2nd to-be-latched surface 9E in the state which contacted the bottom part 9F, The position where the first locked surface 9D and the second locked surface 9E are in contact is located between the guide surfaces 9G and 9H and the bottom portion 9F.

Each cut-and-raised piece 55 is positioned such that the connecting portion 55B with the side wall portions 5A and 5B is located on the other end side in the longitudinal direction of the movable rail 5 from the front end portion 55C (in the present embodiment, on the vehicle rear side). It is cut and raised to form a substantially L shape.

このため、各側壁部５Ａ、５Ｂのうち連結部５５Ｂから長手方向一端側（本実施形態では、車両前方側）に向かう所定の範囲には、図１４Ａに示すように、当該側壁部５Ａ、５Ｂを貫通する貫通穴５５Ｄが発生する。   For this reason, as shown to FIG. 14A, as shown to FIG. 14A, the said side wall part 5A, 5B exists in the predetermined range which goes to the longitudinal direction one end side (this embodiment vehicle front side) from each connection part 55B among 5A, 5B. A through hole 55D penetrating through is generated.

各被係止部５５Ａは、各切り起こし片５５の上端部５５Ｅから可動側レール５の開放側（鉛直方向下方側）に向かう向きに窪んだＵ字状の窪み部である。そして、第２係止部７６は、切り起こし片５５の厚み方向（本実施形態では、幅方向）に各被係止部５５Ａを貫通している。   Each locked portion 55 </ b> A is a U-shaped dent that is recessed from the upper end portion 55 </ b> E of each cut and raised piece 55 toward the open side (vertically in the vertical direction) of the movable rail 5. And the 2nd latching | locking part 76 has penetrated each to-be-latched part 55A in the thickness direction (this embodiment width direction) of the cut-and-raised piece 55. FIG.

つまり、本実施形態では、各切り起こし片５５は車両後方側から車両前方側に延びる突出片にて構成され、かつ、第２係止部７６は、鉛直方向上端から各切り起こし片５５に引っ掛けられて係止されている。   That is, in this embodiment, each cut-and-raised piece 55 is configured by a protruding piece extending from the vehicle rear side to the vehicle front side, and the second locking portion 76 is hooked on each cut-and-raised piece 55 from the upper end in the vertical direction. Is locked.

６．解除部材の可動側レールへの組付構造等
＜組付構造＞
解除部材９は、上述したように、第１弾性変形部７Ｂと蓋壁部５Ｃとの間に配設されている。そして、可動側レール５の長手方向一端側（本実施形態では、車両前方側）には、図９に示すように、規制部５６が設けられている。 6). Assembly structure of release member to movable rail <Assembly structure>
As described above, the release member 9 is disposed between the first elastic deformation portion 7B and the lid wall portion 5C. And the control part 56 is provided in the longitudinal direction one end side (this embodiment vehicle front side) of the movable rail 5 as shown in FIG.

規制部５６は、図１５に示すように、第１弾性変形部７Ｂと蓋壁部５Ｃとの間に挿入側端部が挿入可能な空間を確保するための部位である。挿入側端部とは、解除部材９のうちロック部７Ａ側に位置する端部をいう。   As shown in FIG. 15, the restricting portion 56 is a part for securing a space in which the insertion-side end portion can be inserted between the first elastic deformation portion 7B and the lid wall portion 5C. The insertion side end portion refers to an end portion of the release member 9 positioned on the lock portion 7A side.

換言すれば、規制部５６は、第１弾性変形部７Ｂと蓋壁部５Ｃとの距離が解除部材９の端部高さ寸法Ｔ１以下になることを規制するための部位である。つまり、解除部材９が可動側レール５に組み付けられていない状態では、図１５の二点鎖線で示すように、第１弾性変形部７Ｂが規制部５６に接触する。このため、第１弾性変形部７Ｂと蓋壁部５Ｃとの距離が小さくなることが規制される。   In other words, the restricting portion 56 is a portion for restricting the distance between the first elastic deformation portion 7B and the lid wall portion 5C to be equal to or less than the end height dimension T1 of the release member 9. That is, in a state where the release member 9 is not assembled to the movable rail 5, the first elastic deformation portion 7 </ b> B comes into contact with the restriction portion 56 as indicated by a two-dot chain line in FIG. 15. For this reason, it is regulated that the distance between the first elastic deformation portion 7B and the lid wall portion 5C is reduced.

端部高さ寸法Ｔ１は、図１１に示すように、解除部材９のうちロック部７Ａ側に位置する端部の高さ方向寸法である。本実施形態に係る端部高さ寸法Ｔ１、つまり押圧部９Ａの高さ寸法は、解除部材９のうち高さ寸法が最小となる部位の高さ寸法である。そして、解除部材９の高さ寸法は、押圧部９Ａから支点部９Ｂに向かうほど大きくなっている。   As shown in FIG. 11, the end height dimension T <b> 1 is a height direction dimension of the end portion of the release member 9 located on the lock portion 7 </ b> A side. The end height dimension T1 according to the present embodiment, that is, the height dimension of the pressing portion 9A is the height dimension of the portion of the release member 9 where the height dimension is the smallest. And the height dimension of the cancellation | release member 9 is so large that it goes to the fulcrum part 9B from the press part 9A.

本実施形態に係る規制部５６は、図１５に示すように、一対の側壁部５Ａ、５Ｂそれぞれに設けられている。つまり、第１規制部５６Ａは側壁部５Ａに設けられている。第２規制部５６Ｂは側壁部５Ｂに設けられている。   As shown in FIG. 15, the restriction portion 56 according to the present embodiment is provided on each of the pair of side wall portions 5A and 5B. That is, the first restricting portion 56A is provided on the side wall portion 5A. The second restricting portion 56B is provided on the side wall portion 5B.

そして、第１規制部５６Ａは側壁部５Ａから側壁部５Ｂ側に突出する突出片により構成されている。第２規制部５６Ｂは側壁部５Ｂから側壁部５Ａ側に突出する突出片により構成されている。   And the 1st control part 56A is comprised by the protrusion piece which protrudes from the side wall part 5A to the side wall part 5B side. The second restricting portion 56B includes a protruding piece that protrudes from the side wall portion 5B toward the side wall portion 5A.

第１規制部５６Ａ及び第２規制部５６Ｂを構成する突出片は、高さ方向に対して傾いている。そして、第１規制部５６Ａ及び第２規制部５６Ｂは、各側壁部５Ａ、５Ｂから切り起こされた切り起こし片であり、かつ、その根元側５６Ｃが先端５６Ｄより鉛直方向上方側に位置する。   The protruding pieces constituting the first restricting portion 56A and the second restricting portion 56B are inclined with respect to the height direction. The first restricting portion 56A and the second restricting portion 56B are cut and raised pieces cut and raised from the side wall portions 5A and 5B, and the root side 56C is positioned on the upper side in the vertical direction from the tip 56D.

このため、第１規制部５６Ａ及び第２規制部５６Ｂは、根元側５６Ｃに近づくほど、各側壁部５Ａ、５Ｂに近づくように高さ方向に対して傾斜している。以下、第１規制部５６Ａ及び第２規制部５６Ｂを総称する際には、規制部５６と記す。   For this reason, 56 A of 1st control parts and the 2nd control part 56B are inclined with respect to the height direction so that it may approach each side wall part 5A, 5B, so that the base side 56C is approached. Hereinafter, the first restricting portion 56A and the second restricting portion 56B are collectively referred to as the restricting portion 56.

規制部５６は、図９に示すように、線状部７３及び当該線状部７３の延び方向先端側に接触可能な位置に設けられている。そして、解除部材９には、第１係止部７４が滑り接触可能な摺接部９Ｊが設けられている。   As shown in FIG. 9, the restricting portion 56 is provided at a position that can contact the linear portion 73 and the leading end side in the extending direction of the linear portion 73. The release member 9 is provided with a sliding contact portion 9J with which the first locking portion 74 can come into sliding contact.

摺接部９Ｊは、解除部材９のうち第１弾性変形部７Ｂ側の部位であって、ロック部７Ａ側から係止溝９Ｃに至る部位に設けられている。具体的には、図１１に示すように、押圧部９Ａから係止溝９Ｃに至る下面のうち幅方向両端側の部位が摺接部９Ｊに相当する。   The sliding contact portion 9J is provided in a portion of the release member 9 on the first elastic deformation portion 7B side and extending from the lock portion 7A side to the locking groove 9C. Specifically, as shown in FIG. 11, portions on both ends in the width direction of the lower surface from the pressing portion 9A to the locking groove 9C correspond to the sliding contact portion 9J.

＜組付方法＞
解除部材９を可動側レール５に組み付ける作業においては、作業者等は、先ず、可動側レール５の蓋壁部５Ｃを鉛直方向下側に配置した状態で、ロックスプリング７を可動側レール５に組み付ける。 <Assembly method>
In the operation of assembling the release member 9 to the movable rail 5, an operator or the like first places the lock spring 7 on the movable rail 5 in a state where the cover wall portion 5 </ b> C of the movable rail 5 is disposed on the lower side in the vertical direction. Assemble.

具体的には、作業者等は、ロック部７Ａの係合部７１、７２を各切り欠き部５１、５２に嵌め込むとともに、第２弾性変形部７Ｃの第２係止部７６を被係止部５５Ａに係止する。このとき、第１弾性変形部７Ｂは、線状部７３の先端側及び線状部７３が規制部５６に接触した状態となる（図１５参照）。   Specifically, the operator or the like engages the engaging portions 71 and 72 of the lock portion 7A with the notches 51 and 52 and locks the second locking portion 76 of the second elastic deformation portion 7C. Locks to the portion 55A. At this time, the 1st elastic deformation part 7B will be in the state which the front end side of the linear part 73 and the linear part 73 contacted the control part 56 (refer FIG. 15).

次に、作業者等は、ロックスプリング７と蓋壁部５Ｃとの隙間に解除部材９の押圧部９Ａを挿入する。このとき、第１係止部７４が摺接部９Ｊと滑り接触し、かつ、支点部９Ｂの頂部が蓋壁部５Ｃに滑り接触しながら、解除部材９がロック部７Ａ側に挿入されていく。   Next, an operator or the like inserts the pressing portion 9A of the release member 9 into the gap between the lock spring 7 and the lid wall portion 5C. At this time, the release member 9 is inserted to the lock portion 7A side while the first locking portion 74 is in sliding contact with the sliding contact portion 9J and the top of the fulcrum portion 9B is in sliding contact with the lid wall portion 5C. .

そして、第１係止部７４が係止溝９Ｃに嵌り込んだときに、解除部材９を挿入する作業が終了する。なお、第１係止部７４が係止溝９Ｃに嵌り込むと、挿入に必要な力が急激に増大するので、作業者等は、第１係止部７４が係止溝９Ｃに嵌り込んだことを容易に感知する。   Then, when the first locking portion 74 is fitted in the locking groove 9C, the operation of inserting the release member 9 is completed. In addition, since the force required for insertion will increase rapidly when the 1st latching | locking part 74 fits in the latching groove 9C, the operator etc. fit the 1st latching | locking part 74 in the latching groove 9C. I sense it easily.

７．本実施形態に係るシート用スライド装置の特徴
本実施形態では、図１３に示すように、第１係止部７４が第１被係止面９Ｄと第２被係止面９Ｅとにより挟まれた構成となる。このため、解除部材９を引き抜く向きの力、つまり引き抜き力が解除部材９に作用した場合であっても、第１係止部７４と線状部７３とのなす角が拡大するような曲げモーメントが第１係止部７４に作用し難い構成となる。 7). Characteristics of Slide Device for Seat According to this Embodiment In this embodiment, as shown in FIG. 13, the first locking portion 74 is sandwiched between the first locked surface 9D and the second locked surface 9E. It becomes composition. For this reason, even when a force in the direction of pulling out the release member 9, that is, when a pulling force acts on the release member 9, a bending moment that increases the angle formed by the first locking portion 74 and the linear portion 73. However, it is difficult to act on the first locking portion 74.

したがって、本実施形態では、第１係止部７４の根元部、つまり第１係止部７４と線状部７３との連結部で発生する曲げ応力で当該引き抜き力を受けるのではなく、当該根元部の断面で発生する剪断力にて当該引き抜き力を受け得る構成となる。延いては、係止力が大きく低下することを抑制可能なシート用スライド装置１を得ることができ得る。   Therefore, in the present embodiment, the base portion of the first locking portion 74 is not subjected to the pulling force due to the bending stress generated at the connecting portion between the first locking portion 74 and the linear portion 73, but the base portion. It becomes the structure which can receive the said extraction force with the shearing force which generate | occur | produces in the cross section of a part. As a result, it is possible to obtain the seat slide device 1 capable of suppressing a significant decrease in the locking force.

解除部材９のうち係止溝９Ｃ部分の断面形状は閉断面形状であり、かつ、係止溝９Ｃと解除部材９とは金属製の一体成形品である。これにより、第１被係止面９Ｄ及び第２被係止面９Ｅを容易に形成可能となるとともに、解除部材９の剛性を高めることができる。   The cross-sectional shape of the locking groove 9C portion of the releasing member 9 is a closed cross-sectional shape, and the locking groove 9C and the releasing member 9 are a metal integrally formed product. Accordingly, the first locked surface 9D and the second locked surface 9E can be easily formed, and the rigidity of the release member 9 can be increased.

第１係止部７４Ａ及び第２係止部７４Ｂは、第１被係止面９Ｄ及び第２被係止面９Ｅに接触可能な位置に配設されている。これにより、第１係止部７４Ａ及び第２係止部７４Ｂの先端が、係止溝９Ｃ内に位置する構成となるので、各係止部７４Ａ、７４Ｂと各線状部７３Ａ、７３Ｂとのなす角が拡大するような曲げモーメントが第１係止部７４に作用し難い構成となる。   The first locking portion 74A and the second locking portion 74B are disposed at positions that can contact the first locked surface 9D and the second locked surface 9E. As a result, the leading ends of the first locking portion 74A and the second locking portion 74B are positioned in the locking groove 9C, so that the locking portions 74A, 74B and the linear portions 73A, 73B are formed. A bending moment that increases the angle is unlikely to act on the first locking portion 74.

第１係止部７４と第１被係止面９Ｄ及び第２被係止面９Ｅとが接触する位置は、図１２に示すように、解除部材９の高さ方向一端と高さ方向他端との間の位置となっている。これにより、第１係止部７４が解除部材９から高さ方向にずれた位置で解除部材９に係止された構成に比べて、可動側レール５、つまりシート用スライド装置１の高さ寸法を小型にすることが可能となる。   As shown in FIG. 12, the position where the first locking portion 74 contacts the first locked surface 9 </ b> D and the second locked surface 9 </ b> E is one end in the height direction and the other height direction of the release member 9. The position is between. Accordingly, the height dimension of the movable rail 5, that is, the seat slide device 1, compared to the configuration in which the first locking portion 74 is locked to the release member 9 at a position shifted in the height direction from the release member 9. Can be made smaller.

一対の側壁部５Ａ、５Ｂが各線状部７３に接触することにより、図１３に示すように、第１係止部７４が第１被係止面９Ｄ及び第２被係止面９Ｅから離間する方向に変位することが規制されている。これにより、第１係止部７４と線状部７３とのなす角が拡大するような曲げモーメントが第１係止部７４に作用し難い構成を確実に保持可能となる。   When the pair of side wall portions 5A and 5B come into contact with each linear portion 73, the first locking portion 74 is separated from the first locked surface 9D and the second locked surface 9E as shown in FIG. Displacement in the direction is restricted. As a result, it is possible to reliably hold a configuration in which a bending moment that increases the angle formed by the first locking portion 74 and the linear portion 73 does not easily act on the first locking portion 74.

第１規制部５Ｇ及び第２規制部５Ｈが、図９に示すように、第１被係止面９Ｄ又は第２被係止面９Ｅとロック部７Ａとの間に設けられている。これにより、可動側レール５に対して解除部材９が第１係止部７４の突出方向と略平行な方向に変位することを規制される。したがって、第１係止部７４と線状部７３とのなす角が拡大するような曲げモーメントが第１係止部７４に作用し難い構成を確実に保持可能となる。   As shown in FIG. 9, the first restricting portion 5G and the second restricting portion 5H are provided between the first locked surface 9D or the second locked surface 9E and the lock portion 7A. Thereby, the release member 9 is restricted from being displaced in a direction substantially parallel to the protruding direction of the first locking portion 74 with respect to the movable rail 5. Therefore, it is possible to reliably hold a configuration in which a bending moment that increases the angle formed by the first locking portion 74 and the linear portion 73 does not easily act on the first locking portion 74.

第１被係止面９Ｄ及び第２被係止面９Ｅそれぞれの高さ方向一端側（本実施形態では、下端側）に、図１２に示すように、傾斜した案内面９Ｇ、９Ｈが設けられている。これにより、第１係止部７４を容易に係止溝９Ｃに装着でき得る。   As shown in FIG. 12, inclined guide surfaces 9G and 9H are provided on one end side in the height direction of each of the first locked surface 9D and the second locked surface 9E (the lower end side in this embodiment). ing. Thereby, the 1st latching | locking part 74 can be easily mounted in the latching groove 9C.

図１５に示すように、第１弾性変形部７Ｂと蓋壁部５Ｃとの距離が解除部材９の端部高さ寸法Ｔ１以下になることを規制する規制部５６が設けられている。これにより、作業者等は、可動側レール５の長手方向一端側から解除部材９を当該可動側レール５内に容易に挿入組み付けできる。   As shown in FIG. 15, a restricting portion 56 is provided that restricts the distance between the first elastically deforming portion 7 </ b> B and the lid wall portion 5 </ b> C from being equal to or less than the end height dimension T <b> 1 of the release member 9. Thereby, an operator or the like can easily insert and assemble the release member 9 into the movable side rail 5 from one end side in the longitudinal direction of the movable side rail 5.

すなわち、作業者等が解除部材９を可動側レール５内に挿入する際に、仮に、第１弾性変形部７Ｂが蓋壁部５Ｃに近接していると、当該第１弾性変形部７Ｂが障害となって解除部材９を可動側レール５内に挿入できない。   That is, when the operator or the like inserts the release member 9 into the movable rail 5, if the first elastic deformation portion 7B is close to the lid wall portion 5C, the first elastic deformation portion 7B becomes an obstacle. Thus, the release member 9 cannot be inserted into the movable rail 5.

しかし、本実施形態では、第１弾性変形部７Ｂと蓋壁部５Ｃとの距離が解除部材９の端部高さ寸法Ｔ１以下になることを規制する規制部５６が可動側レール５の長手方向一端側に設けられている。   However, in the present embodiment, the regulating portion 56 that regulates that the distance between the first elastically deforming portion 7B and the lid wall portion 5C is equal to or less than the end height T1 of the release member 9 is the longitudinal direction of the movable rail 5 It is provided on one end side.

このため、解除部材９が可動側レール５に挿入される際に、第１弾性変形部７Ｂが障害となることを抑制できる。したがって、解除部材９を可動側レール５内に容易に挿入でき得る。なお、作業者等とは、解除部材９の組み付け作業を行う自動組付装置又は組付作業者等をいう。   For this reason, when the cancellation | release member 9 is inserted in the movable side rail 5, it can suppress that the 1st elastic deformation part 7B becomes an obstruction. Accordingly, the release member 9 can be easily inserted into the movable rail 5. In addition, an operator etc. means the automatic assembly apparatus or assembly worker etc. which perform the assembly | attachment operation | work of the cancellation | release member 9. FIG.

規制部５６は、一対の側壁部５Ａ、５Ｂのうち一方の側壁部５Ａ、５Ｂから他方の側壁部５Ａ、５Ｂ側に突出した突出片により構成されており、規制部５６をなす突出片は、高さ方向に対して傾いている。   The restricting portion 56 is configured by a protruding piece that protrudes from the one side wall portion 5A, 5B to the other side wall portion 5A, 5B of the pair of side wall portions 5A, 5B. Inclined with respect to the height direction.

これにより、規制部５６に接触した線状部７３は、規制部５６と各側壁部５Ａ、５Ｂとで挟まれた状態となり得る。したがって、第１弾性変形部７Ｂが解除部材９の挿入を妨げることを確実に防止でき得る。   Thereby, the linear part 73 which contacted the control part 56 can be in the state pinched | interposed by the control part 56 and each side wall part 5A, 5B. Therefore, the first elastic deformation portion 7B can be reliably prevented from interfering with the insertion of the release member 9.

解除部材９のうち第１弾性変形部７Ｂ側であってロック部７Ａ側から被係止部９Ｃに至る部位には、第１係止部７４が滑り接触可能な摺接部９Ｊが設けられている。これにより、解除部材９を可動側レール５内に容易に挿入でき得る。   In the part of the release member 9 that is on the first elastic deformation portion 7B side and extends from the lock portion 7A side to the locked portion 9C, a sliding contact portion 9J that allows the first locking portion 74 to come into sliding contact is provided. Yes. As a result, the release member 9 can be easily inserted into the movable rail 5.

ところで、特許文献１において、第２係止部７６に相当する部位が係止される切り起こし片は、側壁部と連結部が先端部より鉛直方向下方側、つまり固定側レール側に位置するように側壁部から切り起こされてＬ字状となっている。   By the way, in Patent Document 1, the cut-and-raised piece to which the portion corresponding to the second locking portion 76 is locked is such that the side wall portion and the connecting portion are located on the lower side in the vertical direction than the tip portion, that is, on the fixed rail side. It is cut and raised from the side wall portion to form an L shape.

そして、Ｌ字状の切り起こし片に沿って連結部から先端部に至る長さを「必要切起長さ」としたとき、切り起こし片が設けられた部位には、必然的に、「必要切起長さ」より大きな貫通穴（以下、切り起こし穴という。）が形成されてしまう。   And when the length from the connecting portion to the tip portion along the L-shaped cut and raised piece is “necessary cut and raised length”, the portion where the cut and raised piece is provided is necessarily “necessary” A through hole larger than the “cut-and-raised length” (hereinafter referred to as a cut-and-raised hole) is formed.

このため、特許文献１に記載の発明では、可動側レールの鉛直方向寸法を「必要切起長さ」より小さくすることが難しい。すなわち、仮に、可動側レールの鉛直方向寸法を「必要切起長さ」より小さくすると、切り起こし穴が蓋壁部まで到達してしまう。   For this reason, in the invention described in Patent Document 1, it is difficult to make the vertical dimension of the movable rail smaller than the “necessary cut and raised length”. That is, if the vertical dimension of the movable rail is made smaller than the “necessary cut and raised length”, the cut and raised hole reaches the lid wall.

このため、可動側レールの断面二次モーメントが小さくなり、可動側レールの曲げ剛性が大きく低下するおそれがある。したがって、可動側レールの鉛直方向寸法を小さくすることが難しい。   For this reason, the sectional secondary moment of the movable rail becomes small, and the bending rigidity of the movable rail may be greatly reduced. Therefore, it is difficult to reduce the vertical dimension of the movable rail.

これに対して、本実施形態では、切り起こし片５５は、側壁部５Ａ、５Ｂとの連結部５５Ｂが先端部５５Ｃより可動側レール５の長手方向他端側に位置するように形成されている。   In contrast, in the present embodiment, the cut-and-raised piece 55 is formed so that the connecting portion 55B with the side wall portions 5A and 5B is located on the other end side in the longitudinal direction of the movable rail 5 from the tip portion 55C. .

そして、蓋壁部５Ｃ側から可動側レール５の開放側に向かう向きと略平行な方向が鉛直方向と一致するように、シート用スライド装置１が車両等に搭載されるので、「必要切起長さ」の方向が水平方向、つまり可動側レール５の長手方向に一致する。   Since the seat slide device 1 is mounted on the vehicle or the like so that the direction substantially parallel to the opening direction of the movable rail 5 from the lid wall 5C side coincides with the vertical direction, The direction of “length” coincides with the horizontal direction, that is, the longitudinal direction of the movable rail 5.

したがって、切り起こし穴が蓋壁部５Ｃまで到達してしまうことを抑制できるので、可動側レール５の曲げ剛性が低下することを抑制しながら、可動側レール５の鉛直方向寸法を小型にすることが可能となる。   Accordingly, since the cut-and-raised hole can be prevented from reaching the cover wall portion 5C, the vertical dimension of the movable-side rail 5 can be reduced while suppressing the bending rigidity of the movable-side rail 5 from being lowered. Is possible.

さらに、切り起こし片５５は、側壁部５Ａ、５Ｂとの連結部５５Ｂが先端部５５Ｃより可動側レール５の長手方向他端側に位置するようにして形成されているので、第２弾性変形部７Ｃを被係止部５５Ａに係止する際、及び第２弾性変形部７Ｃが弾性変形する際に、当該切り起こし片５５が障害となってしまうことを抑制できる。   Further, the cut and raised piece 55 is formed such that the connecting portion 55B with the side wall portions 5A and 5B is located on the other end side in the longitudinal direction of the movable rail 5 from the tip portion 55C. When the 7C is locked to the locked portion 55A and when the second elastic deformation portion 7C is elastically deformed, it is possible to suppress the cut and raised piece 55 from becoming an obstacle.

As a result, the assembly workability can be improved.

なお、第１規制部５６Ａ及び第２規制部５６Ｂの切り起こし角θ（図１８参照）は、上述の実施形態に係る第１規制部５６Ａ及び第２規制部５６Ｂの切り起こし角より大きい。これは、解除部材９と規制部５６との干渉を回避するためである。   Note that the cut-and-raised angle θ (see FIG. 18) of the first restricting portion 56A and the second restricting portion 56B is larger than the cut-and-raised angle of the first restricting portion 56A and the second restricting portion 56B according to the above-described embodiment.
