　第３のプレート７０には、スリットコーナ部７２ｃによって規定される空間が形成されており、この空間が第３のスリットである。第３のスリットは、切欠き部７２の一部を構成している。第３のプレート７０はロアレール４０に固定されており、第３のスリットはロアレール４０に設けられているといえる。第４のプレート８０には、スリットコーナ部８２ｃによって規定される空間が形成されており、この空間が第４のスリットである。第４のスリットは、切欠き部８２の一部を構成している。第３のスリットと第４のスリットとの少なくとも一部は、円弧の形状を有している。この円弧の半径は、丸棒形状のピン９３の半径と等しくなっている。 A space defined by the slit corner portion 72c is formed in the third plate 70, and this space is the third slit. The third slit constitutes a part of the notch 72. It can be said that the third plate 70 is fixed to the lower rail 40 and the third slit is provided in the lower rail 40. A space defined by the slit corner portion 82c is formed in the fourth plate 80, and this space is the fourth slit. The fourth slit constitutes a part of the notch portion 82. At least a part of the third slit and the fourth slit has an arc shape. The radius of the arc is equal to the radius of the round bar-shaped pin 93.
　図７は、プレートを固定する位置固定部の構成を示す分解斜視図である。図７には、第３のプレート７０の貫通孔７５を含む一部分と、第４のプレート８０の貫通孔８５を含む一部分とが、図示されている。 FIG. 7 is an exploded perspective view showing the configuration of the position fixing portion for fixing the plate. In FIG. 7, a part including the through hole 75 of the third plate 70 and a part including the through hole 85 of the fourth plate 80 are illustrated.
　図７に示すように、貫通孔８５は、平面視した形状が円の丸孔である。貫通孔７５は、平面視した形状が角丸長方形の長孔である。貫通孔７５の長軸方向は、前後方向である。貫通孔７５の長軸方向は、第３のプレート７０と第４のプレート８０との相対移動方向である。貫通孔７５の長軸方向は、ロアレール４０に対して相対的にスライド移動するアッパレール３０の移動方向である。貫通孔７５の長軸方向の寸法は、丸棒形状のピン９３の半径よりも大きく設定されている。 As shown in FIG. 7, the through hole 85 is a circular hole having a circular shape in plan view. The through hole 75 is a long hole having a rounded rectangular shape in plan view. The major axis direction of the through hole 75 is the front-rear direction. The major axis direction of the through hole 75 is a relative movement direction between the third plate 70 and the fourth plate 80. The long axis direction of the through hole 75 is the moving direction of the upper rail 30 that slides relative to the lower rail 40. The dimension of the through-hole 75 in the major axis direction is set larger than the radius of the round bar-shaped pin 93.
　第３のプレート７０と第４のプレート８０とは、貫通孔７５，８５にボルト１７５を挿通してボルト１７５を固定ナット部８７（図５）に締結することにより、固定される。そのため、第３のプレート７０と第４のプレート８０とを互いに固定した状態で、貫通孔７５と貫通孔８５とは、互いに重なり合っている。ボルト１７５は、貫通孔７５および貫通孔８５に挿通される挿通部材である。貫通孔７５，８５に挿通されるボルト１７５は、第３のプレート７０と第４のプレート８０とを固定する、第２の位置固定部に相当する。 The third plate 70 and the fourth plate 80 are fixed by inserting the bolts 175 through the through holes 75 and 85 and fastening the bolts 175 to the fixing nut portion 87 (FIG. 5). Therefore, in a state where the third plate 70 and the fourth plate 80 are fixed to each other, the through hole 75 and the through hole 85 overlap each other. The bolt 175 is an insertion member that is inserted through the through hole 75 and the through hole 85. The bolt 175 inserted through the through holes 75 and 85 corresponds to a second position fixing portion that fixes the third plate 70 and the fourth plate 80.
　貫通孔７５が長孔であるため、ボルト１７５が貫通孔７５，８５に挿通されているが第３のプレート７０と第４のプレート８０とは未だ固定されていない状態で、第４のプレート８０は、第３のプレート７０およびロアレール４０に対して前後方向に相対的にスライド移動可能である。 Since the through hole 75 is a long hole, the bolt 175 is inserted into the through holes 75 and 85, but the third plate 70 and the fourth plate 80 are not yet fixed, and the fourth plate 80 Is slidable relative to the third plate 70 and the lower rail 40 in the front-rear direction.
　図７では、第３のプレート７０の貫通孔７５と第４のプレート８０の貫通孔８５とについて説明したが、第３のプレート７０の貫通孔７４と第４のプレート８０の貫通孔８４ともまた、貫通孔７５，８５と同様に構成されている。貫通孔８４は丸孔であり、貫通孔７４は前後方向に延びる長孔である。第３のプレート７０と第４のプレート８０とを互いに固定した状態で、貫通孔７４と貫通孔８４とは、互いに重なり合っている。ボルト１７４は、貫通孔７４および貫通孔８４に挿通される挿通部材である。 In FIG. 7, the through hole 75 of the third plate 70 and the through hole 85 of the fourth plate 80 have been described. However, the through hole 74 of the third plate 70 and the through hole 84 of the fourth plate 80 are also described. The configuration is the same as the through holes 75 and 85. The through hole 84 is a round hole, and the through hole 74 is a long hole extending in the front-rear direction. In a state where the third plate 70 and the fourth plate 80 are fixed to each other, the through hole 74 and the through hole 84 overlap each other. The bolt 174 is an insertion member that is inserted into the through hole 74 and the through hole 84.
　さらに、第２のプレート６０に形成された貫通孔６４，６５と、第１のプレート５０の固定ナット部５４，５５に相当する位置に形成された貫通孔ともまた、貫通孔７５，８５と同様に構成されている。第１のプレート５０の貫通孔は丸孔であり、貫通孔６４，６５は前後方向に延びる長孔である。第１のプレート５０と第２のプレート６０とを互いに固定した状態で、第１のプレート５０の固定ナット部５４に相当する貫通孔と第２のプレート６０の貫通孔６４とが互いに重なり合い、第１のプレート５０の固定ナット部５５に相当する貫通孔と第２のプレート６０の貫通孔６５とが互いに重なり合っている。ボルト１６４，１６５は、挿通部材である。ボルト１６４，１６５は、第１のプレート５０と第２のプレート６０とを固定する、第１の位置固定部に相当する。 Further, the through holes 64 and 65 formed in the second plate 60 and the through holes formed at positions corresponding to the fixing nut portions 54 and 55 of the first plate 50 are also the same as the through holes 75 and 85. It is configured. The through holes of the first plate 50 are round holes, and the through holes 64 and 65 are long holes extending in the front-rear direction. In a state where the first plate 50 and the second plate 60 are fixed to each other, the through hole corresponding to the fixing nut portion 54 of the first plate 50 and the through hole 64 of the second plate 60 overlap each other, The through hole corresponding to the fixing nut portion 55 of the first plate 50 and the through hole 65 of the second plate 60 overlap each other. Bolts 164 and 165 are insertion members. The bolts 164 and 165 correspond to a first position fixing unit that fixes the first plate 50 and the second plate 60.
　図８は、ピン９３をスリットに当接させる前の状態を示す平面図である。図８および後述する図９には、キー部９０が有する２つのピン９３，９４のうちの一方のピン９３と、第１のプレート５０に形成された切欠き部５２と、第２のプレート６０に形成された切欠き部６２とが、図示されている。 FIG. 8 is a plan view showing a state before the pin 93 is brought into contact with the slit. In FIG. 8 and FIG. 9 described later, one pin 93 of the two pins 93 and 94 included in the key portion 90, the cutout portion 52 formed in the first plate 50, and the second plate 60. A notch 62 is formed in the figure.
　図５を併せて参照して、キー部９０のピン９３，９４をそれぞれ第２のプレート６０の切欠き部６２，６３内に配置し、続いて第１のプレート５０を第２のプレート６０に重ね合わせて、その状態でボルト１６４，１６５を固定ナット部５４、５５にそれぞれ仮止めする。これにより、切欠き部５２と切欠き部６２とが重なり合って形成された空間内にピン９３が配置され、切欠き部５３と切欠き部６３とが重なり合って形成された空間内にピン９４が配置される。 Referring also to FIG. 5, the pins 93 and 94 of the key portion 90 are respectively disposed in the notches 62 and 63 of the second plate 60, and then the first plate 50 is attached to the second plate 60. In this state, the bolts 164 and 165 are temporarily fixed to the fixing nut portions 54 and 55, respectively. As a result, the pin 93 is disposed in the space formed by overlapping the notch 52 and the notch 62, and the pin 94 is formed in the space formed by overlapping the notch 53 and the notch 63. Be placed.
　貫通孔６４，６５が長孔であるため、ボルト１６４，１６５が貫通孔６４，６５に挿通されて固定ナット部５４，５５に仮止めされているが第１のプレート５０と第２のプレート６０とは未だ固定されていない状態で、第１のプレート５０は、第２のプレート６０およびアッパレール３０に対して前後方向に相対的にスライド移動可能である。そのため、図８に示すように、第１のプレート５０のスリットコーナ部５２ｃと第２のプレート６０のスリットコーナ部６２ｃとを前後方向（図８中の左右方向）に離すように、第１のプレート５０と第２のプレート６０とを配置することが可能である。 Since the through holes 64 and 65 are long holes, the bolts 164 and 165 are inserted into the through holes 64 and 65 and temporarily fixed to the fixing nut portions 54 and 55, but the first plate 50 and the second plate 60. The first plate 50 is slidable relative to the second plate 60 and the upper rail 30 in the front-rear direction in an unfixed state. Therefore, as shown in FIG. 8, the first corner 50c of the first plate 50 and the slit corner 62c of the second plate 60 are separated from each other in the front-rear direction (left-right direction in FIG. 8). It is possible to arrange the plate 50 and the second plate 60.
　このとき、スリットコーナ部５２ｃ，６２ｃを組み合わせて形成されたスリットを平面視した形状は、スリットコーナ部５２ｃの円弧と、スリットコーナ部６２ｃの円弧と、これら２つの円弧を繋ぐ直線とを含んでいる。スリットが直線の形状を含むことにより、図８に示すように、スリット内に配置されたピン９３は、スリットコーナ部５２ｃ，６２ｃの一方または両方に対して接触していない。スリットが幅広に形成されているため、スリットにピン９３を容易に挿通することが可能になっている。 At this time, the shape of the slit formed by combining the slit corner portions 52c and 62c in plan view includes an arc of the slit corner portion 52c, an arc of the slit corner portion 62c, and a straight line connecting these two arcs. Yes. Since the slit includes a linear shape, as shown in FIG. 8, the pin 93 disposed in the slit is not in contact with one or both of the slit corner portions 52c and 62c. Since the slit is formed wide, the pin 93 can be easily inserted into the slit.
　図９は、ピン９３をスリットに当接させた状態を示す平面図である。図８に示す、スリットにピン９３を挿通した状態で、第１のプレート５０を第２のプレート６０およびアッパレール３０に対して前後方向（図９中の左右方向）に相対移動させる。より具体的には、図８に示す配置から、第２のプレート６０を前方向（図９中の右方向）へ移動させる。これにより、第１のプレート５０は、第２のプレート６０およびアッパレール３０に対して、後方向にずれて配置される。 FIG. 9 is a plan view showing a state in which the pin 93 is in contact with the slit. In a state where the pin 93 is inserted into the slit shown in FIG. 8, the first plate 50 is moved relative to the second plate 60 and the upper rail 30 in the front-rear direction (left-right direction in FIG. 9). More specifically, the second plate 60 is moved in the forward direction (right direction in FIG. 9) from the arrangement shown in FIG. Thereby, the first plate 50 is disposed so as to be shifted rearward with respect to the second plate 60 and the upper rail 30.
　図９に示すように、第１のプレート５０のスリットコーナ部５２ｃと第２のプレート６０のスリットコーナ部６２ｃとの両方がピン９３の外周面に接触するように、第１のプレート５０と第２のプレート６０とを配置することが可能である。第１のプレート５０を第２のプレート６０およびアッパレール３０に対して相対的にスライド移動させ、第１のプレート５０と第２のプレート６０との両方をピン９３に当接させた位置で、第１のプレート５０と、第２のプレート６０およびアッパレール３０とは、ボルト１６４，１６５を用いて固定され、相対移動不能とされる。 As shown in FIG. 9, the first plate 50 and the first plate 50 are arranged so that both the slit corner portion 52 c of the first plate 50 and the slit corner portion 62 c of the second plate 60 are in contact with the outer peripheral surface of the pin 93. Two plates 60 can be arranged. The first plate 50 is slid relative to the second plate 60 and the upper rail 30, and the first plate 50 and the second plate 60 are both brought into contact with the pins 93 at the first position. The first plate 50, the second plate 60, and the upper rail 30 are fixed using bolts 164 and 165, and cannot be relatively moved.
　ボルト１６４，１６５を用いて固定された第１のプレート５０は、第１のプレート５０とアッパレール３０との相対移動方向における一方で、ピン９３に当接している。第１のプレート５０は、ピン９３の外周面の前方側に当接している。ボルト１６４，１６５を用いて固定された第２のプレート６０は、第１のプレート５０とアッパレール３０との相対移動方向における他方で、ピン９３に当接している。第２のプレート６０は、ピン９３の外周面の後方側に当接している。 The first plate 50 fixed using the bolts 164 and 165 is in contact with the pin 93 on the one hand in the relative movement direction between the first plate 50 and the upper rail 30. The first plate 50 is in contact with the front side of the outer peripheral surface of the pin 93. The second plate 60 fixed using the bolts 164 and 165 is in contact with the pin 93 on the other side in the relative movement direction between the first plate 50 and the upper rail 30. The second plate 60 is in contact with the rear side of the outer peripheral surface of the pin 93.

Typically, the shape of the slit in plan view is a semicircular shape. As shown in FIG. 9, the pin 93 disposed in the slit is in contact with both the slit corner portions 52c and 62c. Therefore, no gap is formed between the pin 93 disposed in the slit and the first plate 50, and no gap is formed between the pin 93 disposed in the slit and the second plate 60. .
　図１０は、ピン９３をスリットに当接させた状態を示す側面図である。図１０に示す配置において、第１のプレート５０と第２のプレート６０とは、図９を参照して説明した通り位置を調整されている。ピン９３は、第１のプレート５０および第２のプレート６０のスリットコーナ部５２ｃ，６２ｃの両方に接触している。 FIG. 10 is a side view showing a state in which the pin 93 is in contact with the slit. In the arrangement shown in FIG. 10, the positions of the first plate 50 and the second plate 60 are adjusted as described with reference to FIG. The pin 93 is in contact with both the slit corner portions 52 c and 62 c of the first plate 50 and the second plate 60.
　ピン９３は、第３のプレート７０の切欠き部７２と、第４のプレート８０の切欠き部８２との両方にも挿通されている。第３のプレート７０のスリットコーナ部７２ｃと第４のプレート８０のスリットコーナ部８２ｃとを組み合わせて形成されたスリットに、ピン９３が挿通された状態で、第３のプレート７０およびロアレール４０は前方向へ移動している。これにより、第３のプレート７０およびロアレール４０は、第４のプレート８０に対して、前方向にずれて配置される。 The pin 93 is inserted into both the cutout portion 72 of the third plate 70 and the cutout portion 82 of the fourth plate 80. The third plate 70 and the lower rail 40 are in front of each other with the pin 93 inserted through a slit formed by combining the slit corner portion 72c of the third plate 70 and the slit corner portion 82c of the fourth plate 80. Moving in the direction. As a result, the third plate 70 and the lower rail 40 are arranged so as to be shifted in the forward direction with respect to the fourth plate 80.
　第３のプレート７０と第４のプレート８０とは、スリットコーナ部７２ｃ，８２ｃの両方がピン９３の外周面に接触するように、配置されている。第４のプレート８０を第３のプレート７０およびロアレール４０に対して相対的にスライド移動させ、第３のプレート７０と第４のプレート８０との両方をピン９３に当接させた位置で、第３のプレート７０およびロアレール４０と、第４のプレート８０とは、ボルト１７４，１７５を用いて固定され、相対移動不能とされる。 The third plate 70 and the fourth plate 80 are arranged so that both the slit corner portions 72 c and 82 c are in contact with the outer peripheral surface of the pin 93. The fourth plate 80 is slid relative to the third plate 70 and the lower rail 40, and the third plate 70 and the fourth plate 80 are in contact with the pins 93 at the positions where the The third plate 70 and the lower rail 40 and the fourth plate 80 are fixed using bolts 174 and 175 so that they cannot move relative to each other.
　ボルト１７４，１７５を用いて固定された第４のプレート８０は、第３のプレート７０と第４のプレート８０との相対移動方向における一方で、ピン９３に当接している。第４のプレート８０は、ピン９３の外周面の前方側に当接している。ボルト１７４，１７５を用いて固定された第３のプレート７０は、第３のプレート７０と第４のプレート８０との相対移動方向における他方で、ピン９３に当接している。第３のプレート７０は、ピン９３の外周面の後方側に当接している。 The fourth plate 80 fixed using the bolts 174 and 175 is in contact with the pin 93 on the one hand in the relative movement direction between the third plate 70 and the fourth plate 80. The fourth plate 80 is in contact with the front side of the outer peripheral surface of the pin 93. The third plate 70 fixed using the bolts 174 and 175 is in contact with the pin 93 on the other side in the relative movement direction between the third plate 70 and the fourth plate 80. The third plate 70 is in contact with the rear side of the outer peripheral surface of the pin 93.
　図１１は、ピン９３をスリットに当接させた状態を拡大して示す側面図である。図１１中の右方向が前方向、図１１中の左方向が後方向である。図１１中に明確に示されるように、ボルト１６４，１６５により固定された第１のプレート５０は、第２のプレート６０に対して、後方向にずれて配置されている。ボルト１７４，１７５により固定された第３のプレート７０は、第４のプレート８０に対して、前方向にずれて配置されている。第１のプレート５０が第２のプレート６０に対してずれる方向と、第３のプレート７０が第４のプレート８０に対してずれる方向とは、互いに逆向きである。 FIG. 11 is an enlarged side view showing a state where the pin 93 is in contact with the slit. The right direction in FIG. 11 is the forward direction, and the left direction in FIG. 11 is the backward direction. As clearly shown in FIG. 11, the first plate 50 fixed by the bolts 164 and 165 is arranged to be shifted rearward with respect to the second plate 60. The third plate 70 fixed by the bolts 174 and 175 is arranged so as to be shifted in the forward direction with respect to the fourth plate 80. The direction in which the first plate 50 is displaced with respect to the second plate 60 and the direction in which the third plate 70 is displaced with respect to the fourth plate 80 are opposite to each other.
　前後方向において、ボルト１６４，１６５によって固定される以前に第１のプレート５０が第２のプレート６０に対して相対的にスライド移動する方向と、ボルト１７４，１７５によって固定される以前に第３のプレート７０が第４のプレート８０に対して相対的にスライド移動する方向とは、互いに逆向きである。 In the front-rear direction, the first plate 50 slides relative to the second plate 60 before being fixed by the bolts 164, 165, and the third direction before being fixed by the bolts 174, 175.

　図１２は、ピンがスリットから外れた状態を示す車両用シート調整装置２０の平面図である。ハンドル１１１は、図３に示す配置と比較して、右方向（図１２中の左方向）へ操作されている。リンクプレート１１２は、ボルト１１４を中心として、時計回り方向に回転している。 FIG. 12 is a plan view of the vehicle seat adjustment device 20 showing a state in which the pins are removed from the slits. The handle 111 is operated in the right direction (left direction in FIG. 12) as compared with the arrangement shown in FIG. The link plate 112 rotates in the clockwise direction around the bolt 114.
　リンクプレート１１２に形成された貫通孔１１５は、図３と比較して、左方向（図１２中の右方向）へ移動している。図１２に示す貫通孔１１５は、リンク部材１２１を介してリンクプレート１１２と連結されている図３に示すキー部９０から離れる方向へ移動している。キー部９０は、ハンドル１１１の操作に伴って、リンク部材１２１を介して左方向（図１２中の右方向）の力を受けて、図３と比較して左方向（図１２中の右方向）へ移動している。 The through-hole 115 formed in the link plate 112 has moved leftward (rightward in FIG. 12) compared to FIG. The through hole 115 shown in FIG. 12 moves in a direction away from the key portion 90 shown in FIG. 3 connected to the link plate 112 via the link member 121. The key unit 90 receives a force in the left direction (right direction in FIG. 12) via the link member 121 in accordance with the operation of the handle 111, and the left direction (right direction in FIG. 12) compared with FIG. )
　リンクプレート１１２に形成された貫通孔１１６は、図３と比較して、前方向（図１２中の下方向）へ移動している。図１２に示す貫通孔１１６は、リンク部材１２２を介してリンクプレート１１２と連結されている図３に示すキー部９０から離れる方向へ移動している。キー部９０は、ハンドル１１１の操作に伴って、リンク部材１２２を介して右方向（図１２中の左方向）の力を受けて、図３と比較して右方向（図１２中の左方向）へ移動している。 The through-hole 116 formed in the link plate 112 has moved in the forward direction (downward in FIG. 12) compared to FIG. The through hole 116 shown in FIG. 12 moves in a direction away from the key portion 90 shown in FIG. 3 connected to the link plate 112 via the link member 122. The key unit 90 receives a force in the right direction (left direction in FIG. 12) via the link member 122 in accordance with the operation of the handle 111, and thus the right direction (left direction in FIG. 12) compared to FIG. )
　このように、ハンドル１１１の右方向への操作によって、キー部９０を移動させることができる。このキー部９０の移動によって、ピン９３，９４は、スリット内に挿通される係合位置から、スリットから外れる非係合位置へ移動する。キー部９０の移動に伴って、ばね部材１００の一端部１０２（図５）が移動している。これにより、ばね部材１００のコイル部１０１に、付勢力が蓄積されている。 Thus, the key portion 90 can be moved by operating the handle 111 in the right direction. By the movement of the key portion 90, the pins 93 and 94 move from the engagement position inserted through the slit to the non-engagement position that is disengaged from the slit. With the movement of the key part 90, the one end part 102 (FIG. 5) of the spring member 100 is moving. Thereby, the urging force is accumulated in the coil portion 101 of the spring member 100.
　図１３は、スリットから外れたピン９３を示す平面図である。図６と比較して、図１３に示すピン９３は、上述したキー部９０の移動により、スリットから外れる非係合位置へ移動している。 FIG. 13 is a plan view showing the pin 93 removed from the slit. Compared with FIG. 6, the pin 93 shown in FIG. 13 has moved to the non-engagement position that is disengaged from the slit due to the movement of the key portion 90 described above.
　シート３に着座した乗員は、ハンドル１１１を右方向へ操作して、ピン９３とスリットとの係合を解除する。ピン９３がスリットから外れることにより、アッパレール３０は、ロアレール４０に対して前後方向にスライド移動可能になる。アッパレール３０の移動により、シート３が前後方向に移動する。乗員は、前後方向における選択した位置でアッパレール３０をロアレール４０に対して位置決めし、シート３の位置を調整することができる。 The occupant seated on the seat 3 operates the handle 111 in the right direction to release the engagement between the pin 93 and the slit. When the pin 93 is removed from the slit, the upper rail 30 can slide in the front-rear direction with respect to the lower rail 40. As the upper rail 30 moves, the seat 3 moves in the front-rear direction. The occupant can adjust the position of the seat 3 by positioning the upper rail 30 with respect to the lower rail 40 at a selected position in the front-rear direction.
　シート３の位置の調整を終えると、乗員は、ハンドル１１１を左方向へ操作して、図１～３に示す配置へハンドル１１１を戻す。このとき、ばね部材１００に蓄積された付勢力によって、ピン９３，９４は、スリットから外れる非係合位置から、スリット内に挿通される係合位置へ移動する。図１３に示すように、第１のプレート５０は、移動規制部５６を有している。移動規制部５６は、ピン９３のスリットから離れる方向への移動を規制している。 When the adjustment of the position of the seat 3 is completed, the passenger operates the handle 111 to the left to return the handle 111 to the arrangement shown in FIGS. At this time, the pins 93 and 94 are moved from the non-engagement position released from the slit to the engagement position inserted into the slit by the biasing force accumulated in the spring member 100. As shown in FIG. 13, the first plate 50 has a movement restricting portion 56. The movement restricting portion 56 restricts the movement of the pin 93 in the direction away from the slit.
　上述した説明と一部重複する部分もあるが、本実施形態の特徴的な構成を列挙すると以下のようになる。本実施形態の車両用シート調整装置２０は、第１のプレート５０を備えている。第１のプレート５０には、第１のスリットが形成されている。アッパレール３０には、第２のスリットが設けられている。ロアレール４０には、第３のスリットが設けられている。アッパレール３０は第２のプレート６０を有しており、第２のスリットは第２のプレート６０に形成されている。ロアレール４０には第３のプレート７０が取り付けられており、第３のスリットは第３のプレート７０に形成されている。アッパレール３０は、ロアレール４０に対して、前後方向に相対的にスライド移動可能である。第１のプレート５０は、アッパレール３０および第２のプレート６０に対して、前後方向に相対的にスライド移動可能である。 Although there is a part that overlaps with the above description, the characteristic configuration of this embodiment is listed as follows. The vehicle seat adjustment device 20 of the present embodiment includes a first plate 50. A first slit is formed in the first plate 50. The upper rail 30 is provided with a second slit. The lower rail 40 is provided with a third slit. The upper rail 30 has a second plate 60, and the second slit is formed in the second plate 60. A third plate 70 is attached to the lower rail 40, and a third slit is formed in the third plate 70. The upper rail 30 can slide relative to the lower rail 40 in the front-rear direction. The first plate 50 is slidable relative to the upper rail 30 and the second plate 60 in the front-rear direction.
　車両用シート調整装置２０はさらに、ピン９３と、ボルト１６４，１６５とを備えている。図６，１０および１３に示すように、ピン９３は、第１のスリット、第２のスリットおよび第３のスリット内に挿通される係合位置と、第１のスリット、第２のスリットおよび第３のスリットから外れる非係合位置との間で、移動可能である。図７～１１に示すように、第１のプレート５０に形成された第１のスリットと第２のプレート６０に形成された第２のスリットとが互いに重なり合う範囲で、第１のプレート５０をアッパレール３０に対して前後方向に相対的にスライド移動させる。そして、第１のプレート５０とアッパレール３０との相対移動方向における一方で第１のプレート５０を、他方で第２のプレート６０を、係合位置にあるピン９３に当接させた位置で、ボルト１６４，１６５が第１のプレート５０をアッパレール３０に対して固定している。 The vehicle seat adjustment device 20 further includes a pin 93 and bolts 164 and 165. As shown in FIGS. 6, 10, and 13, the pin 93 includes an engagement position inserted into the first slit, the second slit, and the third slit, and the first slit, the second slit, and the first slit. It is possible to move between the non-engagement positions deviating from the three slits. As shown in FIGS. 7 to 11, the first plate 50 is attached to the upper rail within a range in which the first slit formed in the first plate 50 and the second slit formed in the second plate 60 overlap each other. Slide relative to 30 in the front-rear direction. In the relative movement direction of the first plate 50 and the upper rail 30, one of the first plate 50 and the other of the second plate 60 is brought into contact with the pin 93 in the engagement position at the bolt 93. Reference numerals 164 and 165 fix the first plate 50 to the upper rail 30.
　ピン９３を非係合位置に移動させることにより、シート３に固定されたアッパレール３０を、車両フロア１に固定されたロアレール４０に対して、前後方向にスライド移動させることができる。シート３に着座した乗員が選択した位置へシート３を移動させた後、ピン９３を係合位置へ移動させることにより、車両フロア１に対してシート３を位置決めすることができる。このようにして、車両フロア１に対するシート３の位置を調整することができる。 By moving the pin 93 to the non-engagement position, the upper rail 30 fixed to the seat 3 can be slid in the front-rear direction with respect to the lower rail 40 fixed to the vehicle floor 1. The seat 3 can be positioned with respect to the vehicle floor 1 by moving the seat 93 to the position selected by the occupant seated on the seat 3 and then moving the pin 93 to the engagement position. In this way, the position of the seat 3 with respect to the vehicle floor 1 can be adjusted.
　第１のプレート５０と第２のプレート６０とを前後方向に相対的にスライド移動可能とすることにより、第１のプレート５０に形成されたスリットと第２のプレート６０に形成されたスリットとが前後方向において重ね合わせられる範囲を、調整することができる。そのため、第１のプレート５０と第２のプレート６０とによってピン９３を挟むことができ、第１のプレート５０と第２のプレート６０との両方をピン９３に接触させることができる。第１のプレート５０および第２のプレート６０とピン９３との間に隙間が形成されない構成とすることで、車両フロア１に対してシート３を位置決めした状態でのシート３のガタつきを抑制することができる。 By allowing the first plate 50 and the second plate 60 to slide relative to each other in the front-rear direction, a slit formed in the first plate 50 and a slit formed in the second plate 60 are provided. The overlapping range in the front-rear direction can be adjusted. Therefore, the pin 93 can be sandwiched between the first plate 50 and the second plate 60, and both the first plate 50 and the second plate 60 can be brought into contact with the pin 93. By adopting a configuration in which no gap is formed between the first plate 50 and the second plate 60 and the pin 93, rattling of the seat 3 when the seat 3 is positioned with respect to the vehicle floor 1 is suppressed. be able to.
　第１のプレート５０と第２のプレート６０との相対移動によってピン９３との間の隙間をなくすことができるので、第１のプレート５０、第２のプレート６０およびピン９３に厳密な加工精度は必要なく、容易に製造が可能になる。多数製造される車両用シート調整装置２０の全ての個体に対して、同じ手法を適用してガタつきを抑制する調整が可能となるため、生産性を向上することができる。 Since the gap between the pins 93 can be eliminated by the relative movement between the first plate 50 and the second plate 60, the strict processing accuracy of the first plate 50, the second plate 60, and the pins 93 is It is not necessary and can be easily manufactured. Since the same method can be applied to all the individual vehicle seat adjustment devices 20 manufactured in large numbers to suppress the rattling, productivity can be improved.
　経年後に、第１のプレート５０、第２のプレート６０およびピン９３の少なくともいずれか１つが摩耗することにより、第１のプレート５０および第２のプレート６０とピン９３との間に隙間が形成される場合がある。この場合には、第１のプレート５０と第２のプレート６０との前後方向における相対位置を再調整することにより、第１のプレート５０および第２のプレート６０とピン９３との間に隙間が形成されない構成を再び得ることができる。したがって、初期および経年後のいずれにおいても、シート３のガタつきを抑制することができる。 After a lapse of time, at least one of the first plate 50, the second plate 60, and the pin 93 is worn, so that a gap is formed between the first plate 50, the second plate 60 and the pin 93. There is a case. In this case, by adjusting the relative positions of the first plate 50 and the second plate 60 in the front-rear direction, there is a gap between the first plate 50 and the second plate 60 and the pin 93. An unformed configuration can be obtained again. Therefore, rattling of the sheet 3 can be suppressed both in the initial stage and after the lapse of time.
　車両用シート調整装置２０はまた、第４のスリットが形成された第４のプレート８０を備えている。第４のプレート８０は、第３のプレート７０およびロアレール４０に対して、前後方向に相対的にスライド移動可能である。係合位置にあるピン９３は、第３のスリットおよび第４のスリット内に挿通されている。非係合位置にあるピン９３は、第３のスリットおよび第４のスリットから外れている。車両用シート調整装置２０はさらに、ボルト１７４，１７５を備えている。第３のプレート７０に形成された第３のスリットと第４のプレート８０に形成された第４のスリットとが互いに重なり合う範囲で、第４のプレート８０をロアレール４０に対して前後方向に相対的にスライド移動させ第４のプレートをピン９３に当接させた位置で、ボルト１７４，１７５が第４のプレート８０を第３のプレート７０に対して固定している。 The vehicle seat adjustment device 20 also includes a fourth plate 80 in which a fourth slit is formed. The fourth plate 80 is slidable relative to the third plate 70 and the lower rail 40 in the front-rear direction. The pin 93 in the engagement position is inserted through the third slit and the fourth slit. The pin 93 in the non-engagement position is disengaged from the third slit and the fourth slit. The vehicle seat adjustment device 20 further includes bolts 174 and 175. The fourth plate 80 is relative to the lower rail 40 in the front-rear direction within a range in which the third slit formed in the third plate 70 and the fourth slit formed in the fourth plate 80 overlap each other. The bolts 174 and 175 fix the fourth plate 80 to the third plate 70 at a position where the fourth plate is brought into contact with the pin 93 by sliding.
　第３のプレート７０と第４のプレート８０とを前後方向に相対的にスライド移動可能とすることにより、第３のプレート７０と第４のプレート８０とによってピン９３を挟み、第３のプレート７０と第４のプレート８０との両方をピン９３に接触させることができる。第３のプレート７０および第４のプレート８０とピン９３との間に隙間が形成されない構成とすることで、車両フロア１に対してシート３を位置決めした状態でのシート３のガタつきを抑制することができる。 By allowing the third plate 70 and the fourth plate 80 to slide relative to each other in the front-rear direction, the pin 93 is sandwiched between the third plate 70 and the fourth plate 80, and the third plate 70. And the fourth plate 80 can be brought into contact with the pin 93. By adopting a configuration in which no gap is formed between the third plate 70 and the fourth plate 80 and the pin 93, the rattling of the seat 3 in a state where the seat 3 is positioned with respect to the vehicle floor 1 is suppressed. be able to.
　経年後のガタつき調整のために、第１のプレート５０と第２のプレート６０との前後方向における相対位置を再調整することが可能である。一方、第３のプレート７０と第４のプレート８０とのずれを大きくし過ぎると、第３のプレート７０の切欠き部７２と第４のプレート８０の切欠き部８２とによって形成されるスリットへの、ピン９３の挿通が妨げられる。そのため、経年後においても、第３のプレート７０と第４のプレート８０の相対位置は、初期に調整された位置のまま維持されるのが望ましい。 In order to adjust the backlash after the passage of time, it is possible to readjust the relative positions of the first plate 50 and the second plate 60 in the front-rear direction. On the other hand, if the displacement between the third plate 70 and the fourth plate 80 is too large, the slit formed by the cutout portion 72 of the third plate 70 and the cutout portion 82 of the fourth plate 80 is reached. The insertion of the pin 93 is hindered. For this reason, it is desirable that the relative positions of the third plate 70 and the fourth plate 80 be maintained at the initial adjusted positions even after the passage of time.
　また図４に示すように、第１のプレート５０、第２のプレート６０、第３のプレート７０、および第４のプレート８０は、この順に互いに重なり合っている。図１１に示すように、ボルト１６４，１６５により固定された第１のプレート５０は、第２のプレート６０に対して、後方向にずれて配置されている。ボルト１７４，１７５により固定された第３のプレート７０は、第４のプレート８０に対して、前方向にずれて配置されている。 As shown in FIG. 4, the first plate 50, the second plate 60, the third plate 70, and the fourth plate 80 overlap each other in this order. As shown in FIG. 11, the first plate 50 fixed by the bolts 164 and 165 is arranged so as to be shifted rearward with respect to the second plate 60. The third plate 70 fixed by the bolts 174 and 175 is arranged so as to be shifted in the forward direction with respect to the fourth plate 80.
　第１のプレート５０と第２のプレート６０との位置を調整する際の第２のプレート６０に対する第１のプレート５０の移動方向と、第３のプレート７０と第４のプレート８０との位置を調整する際の第４のプレート８０に対する第３のプレート７０の移動方向とが、逆向きになっている。前後方向において、第２のプレート６０および第３のプレート７０がピン９３に後方向から当接し、第１のプレート５０および第４のプレート８０がピン９３に前方向から当接する構成が、実現されている。これにより、第１～４のプレートにより挟まれたピン９３の上下方向に対する傾動を抑制でき、ピン９３を安定して支持することができる。 The movement direction of the first plate 50 relative to the second plate 60 when adjusting the positions of the first plate 50 and the second plate 60 and the positions of the third plate 70 and the fourth plate 80 are determined. The moving direction of the third plate 70 relative to the fourth plate 80 at the time of adjustment is opposite. In the front-rear direction, the configuration in which the second plate 60 and the third plate 70 are in contact with the pins 93 from the rear and the first plate 50 and the fourth plate 80 are in contact with the pins 93 from the front is realized. ing. As a result, the tilt of the pin 93 sandwiched between the first to fourth plates in the vertical direction can be suppressed, and the pin 93 can be stably supported.
　また図１３に示すように、第１のプレート５０は、移動規制部５６を有している。移動規制部５６は、スリットから離れる方向へのピン９３の移動を規制している。移動規制部５６がピン９３の移動範囲を定めているため、非係合位置から係合位置へのピン９３，９４の復帰が容易になっている。したがって、シート３の位置を調整した後、車両フロア１に対してシート３を確実に位置決めすることができる。 As shown in FIG. 13, the first plate 50 has a movement restricting portion 56. The movement restricting portion 56 restricts the movement of the pin 93 in the direction away from the slit. Since the movement restricting portion 56 defines the movement range of the pin 93, the pins 93 and 94 can be easily returned from the non-engagement position to the engagement position. Therefore, the seat 3 can be reliably positioned with respect to the vehicle floor 1 after adjusting the position of the seat 3.
　また図８，９に示すように、ピン９３は、丸棒形状を有している。第１のスリットの一部を構成するスリットコーナ部５２ｃは、円弧の形状を有している。スリットコーナ部５２ｃの円弧の半径は、ピン９３の半径と等しい。スリットの形状とピン９３の形状とを整合させることにより第１のプレート５０と第２のプレート６０との両方を確実にピン９３に接触させ、第１のプレート５０および第２のプレート６０とピン９３との間に隙間が形成されない構成を実現することができる。 Also, as shown in FIGS. 8 and 9, the pin 93 has a round bar shape. The slit corner portion 52c constituting a part of the first slit has an arc shape. The radius of the arc of the slit corner portion 52 c is equal to the radius of the pin 93. By matching the shape of the slit and the shape of the pin 93, both the first plate 50 and the second plate 60 are surely brought into contact with the pin 93, and the first plate 50 and the second plate 60 and the pin are fixed. A configuration in which no gap is formed between the first and second terminals 93 can be realized.
　ピンの形状は、必ずしも丸棒形状に限られるものではなく、ピンの断面を多角形の形状としてもよい。しかしながら、本実施形態のようにスリットの形状とピン９３の形状とを円弧にすることにより、ピン９３がスリット内に挿通される係合位置とピン９３がスリットから外れる非係合位置との間を移動するピン９３が、スリットに対して摺動することなく移動できるので、ピン９３の移動が容易になる。 The shape of the pin is not necessarily limited to the round bar shape, and the cross section of the pin may be a polygonal shape. However, by making the slit shape and the pin 93 into an arc shape as in this embodiment, between the engagement position where the pin 93 is inserted into the slit and the non-engagement position where the pin 93 is removed from the slit. Since the pin 93 that moves is movable without sliding with respect to the slit, the movement of the pin 93 is facilitated.
　また図５，７に示すように、第１のプレート５０に丸穴が形成されており、第２のプレート６０に長孔が形成されている。第２のプレート６０の長孔は、前後方向に延びている。第１のプレート５０の丸孔と第２のプレート６０の長孔とは互いに重なり合っている。ボルト１６４，１６５は、第１のプレート５０の丸孔と第２のプレート６０の長孔とに挿通されている。このようにすれば、第２のプレート６０に形成された長孔の範囲で、第１のプレート５０と第２のプレート６０とを相対的にスライド移動させて、第１のプレート５０と第２のプレート６０との両方をピン９３に確実に接触させることができる。 As shown in FIGS. 5 and 7, a round hole is formed in the first plate 50, and a long hole is formed in the second plate 60. The long hole of the second plate 60 extends in the front-rear direction. The round hole of the first plate 50 and the long hole of the second plate 60 overlap each other. The bolts 164 and 165 are inserted through the round hole of the first plate 50 and the long hole of the second plate 60. In this way, the first plate 50 and the second plate 60 are slid relative to each other within the range of the long holes formed in the second plate 60, and the first plate 50 and the second plate 60 are moved. Both the plate 60 and the pin 93 can be reliably brought into contact with the pin 93.
　図５に示すように、キー部９０は、２本のピン９３，９４を有している。車両フロア１に対してシート３をスライド移動または位置決めする機能を奏するためには、ピンは１本であってもよい。しかしながら、複数のピン９３，９４を有する構成とすることで、キー部９０の強度を向上することができる。 As shown in FIG. 5, the key unit 90 has two pins 93 and 94. In order to achieve the function of sliding or positioning the seat 3 with respect to the vehicle floor 1, the number of pins may be one. However, the strength of the key portion 90 can be improved by adopting a configuration having a plurality of pins 93 and 94.
