Description

[Technical field]

[0001] The present invention relates to a vehicle seat provided with a gap concealing member that conceals a gap between a seat cushion and a rail. [Background technology]

[0002] In the vehicle seat described in Patent Document 1 below, a shield (gap-hiding member) is provided at the rear lower part of the seat, and the shield conceals the rear lower part of the seat. In this shield, a support part rotatably fitted to a support rod rotates together with the support rod, and an engagement pin of the shield moves in a guide groove toward the front of the vehicle, allowing the shield to swing in accordance with the rotation of the seat cushion. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5848088 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with this shield, the engagement pin of the shield moves in the guide groove toward the front of the vehicle to follow the rotation of the seat cushion, so space is required on the front side of the vehicle.

[0005] In consideration of the above, an object of the present invention is to provide a vehicle seat equipped with a gap concealing member that conceals the gap between the seat cushion and a rail without requiring space on the front side of the vehicle. [Means for solving the problem]

[0006] The vehicle seat of the first aspect of the present invention comprises a movable member that moves integrally with a rail that is configured to be movable in the fore-and-aft direction of the vehicle, a seat cushion that is connected to the movable member via a lifter mechanism and is positioned above the rail, and is configured so that its vertical position can be adjusted by the lifter mechanism, and a gap concealing member that extends between a lower rear portion of the seat cushion and the rail to conceal the gap between the seat cushion and the rail, the gap concealing member having an upper end that is rotatably connected to the seat cushion and a lower end that is rotatably connected to the movable member, and the lower end of the upper gap concealing member and the upper end of the lower gap concealing member move toward and away from each other depending on the change in the relative distance between the upper end of the upper gap concealing member and the lower end of the lower gap concealing member.

[0007] In the vehicle seat according to the first aspect of the present invention, the moving member is configured to be movable in the front-rear direction of the vehicle together with the rail. A seat cushion is disposed above the rail and is connected to the moving member via a lifter mechanism. Thus, by moving the rail in the front-rear direction of the vehicle, the position of the seat cushion in the front-rear direction of the vehicle is adjusted, and the position of the seat cushion in the up-down direction is adjusted by the lifter mechanism.

[0008] In addition, a gap concealing member is provided between the vehicle rear lower portion of the seat cushion and the rail, and the gap concealing member conceals the gap between the seat cushion and the rail. As a result, the gap between the seat cushion and the rail is prevented from being visually recognized by the gap concealing member.

[0009] Here, the gap concealing member includes an upper gap concealing member whose upper end is rotatably connected to the seat cushion and a lower gap concealing member whose lower end is rotatably connected to the moving member. Therefore, when the vertical position of the seat cushion is adjusted, the upper end of the upper gap concealing member and the lower end of the lower gap concealing member are rotated in conjunction with the vertical movement of the seat cushion.

[0010] Furthermore, the lower end of the upper gap concealing member and the upper end of the lower gap concealing member move toward and away from each other depending on the change in the relative distance between the upper end of the upper gap concealing member and the lower end of the lower gap concealing member. Therefore, when the seat cushion is adjusted upward, the upper end of the upper gap concealing member rotates while moving upward together with the seat cushion, and the lower end of the lower gap concealing member rotates. Therefore, the upper end of the upper gap concealing member and the lower end of the lower gap concealing member move away from each other, and the lower end of the upper gap concealing member and the upper end of the lower gap concealing member move closer to each other.

[0011] Conversely, when the seat cushion is adjusted downward, the upper end of the upper gap concealing member rotates and moves downward together with the seat cushion, and the lower end of the lower gap concealing member rotates, so that the upper end of the upper gap concealing member and the lower end of the lower gap concealing member approach each other and the lower end of the upper gap concealing member and the upper end of the lower gap concealing member move apart.

[0012] This allows the upper gap concealing member and the lower gap concealing member to move (swing) in accordance with the movement of the seat cushion, and the gap concealing member swings in conjunction with the movement of the seat cushion. At this time, the lower end of the lower gap concealing member rotates with respect to the moving member, but does not move relative to the vehicle in the fore-and-aft direction. This allows the gap concealing member to conceal the gap between the seat cushion and the rail without requiring space on the front side of the vehicle.

[0013] In the second aspect of the vehicle seat of the present invention, in the first aspect, the upper gap concealing member and the lower gap concealing member are moved so that when the seat cushion is positioned at the uppermost position in the vertical direction by the lifter mechanism, the distance between the upper end of the upper gap concealing member and the lower end of the lower gap concealing member is the greatest, and when the seat cushion is positioned at the lowest position in the vertical direction by the lifter mechanism, the distance between the upper end of the upper gap concealing member and the lower end of the lower gap concealing member is the closest.

[0014] In the vehicle seat of the second aspect of the present invention, the upper gap concealing member and the lower gap concealing member are moved so that the distance between the upper end of the upper gap concealing member and the lower end of the lower gap concealing member is the greatest when the seat cushion is positioned at the highest position in the vertical direction by the lifter mechanism. Also, the upper gap concealing member and the lower gap concealing member are moved so that the distance between the upper end of the upper gap concealing member and the lower end of the lower gap concealing member is the closest when the seat cushion is positioned at the lowest position in the vertical direction by the lifter mechanism. In this way, the upper gap concealing member and the lower gap concealing member can expand and contract the length from the upper end of the gap concealing member to the lower end of the lower gap concealing member as the seat cushion moves in the vertical direction, even if there is no space on the front side of the vehicle.

[0015] The vehicle seat of the third aspect of the present invention is the same as that of the first aspect, and includes an engagement portion provided on either the upper gap concealing member or the lower gap concealing member, and a sliding portion provided on the other of the upper gap concealing member or the lower gap concealing member, with which the engagement portion is slidably engaged.

[0016] In the vehicle seat of the third aspect of the present invention, an engagement portion provided on either the upper gap concealing member or the lower gap concealing member is slidably engaged with a sliding portion provided on the other of the upper gap concealing member or the lower gap concealing member. Therefore, the upper gap concealing member and the lower gap concealing member are relatively movable by the sliding portion, and an extension / contraction trajectory of the gap concealing member is set.

[0017] A fourth aspect of the vehicle seat of the present invention is the third aspect, wherein the sliding portion extends along from the upper end side to the lower end side of the other of the upper gap concealing member and the lower gap concealing member.

[0018] In the vehicle seat of the fourth aspect of the present invention, the sliding portion extends from the upper end side to the lower end side of either the upper gap concealing member or the lower gap concealing member. Therefore, the upper gap concealing member and the lower gap concealing member are relatively movable along the sliding portion, and the extension and contraction trajectory of the gap concealing member is set from the upper end side to the lower end side of either the upper gap concealing member or the lower gap concealing member. Here, by forming the sliding portion in accordance with the movement trajectory of the seat cushion when the vertical position of the seat cushion is adjusted, the seat cushion is allowed to move in the vertical direction.

[0019] The vehicle seat of a fifth aspect of the present invention is the vehicle seat of the first aspect, wherein the lower end portion of the lower gap concealing member is disposed forward of the vehicle relative to the upper end portion of the upper gap concealing member.

[0020] In the vehicle seat of the fifth aspect of the present invention, the lower end of the lower gap concealing member is disposed toward the front of the vehicle relative to the upper end of the upper gap concealing member, so that the lower gap concealing member and the upper gap concealing member, i.e., the gap concealing member, are extended downward toward the front of the vehicle, and the lower end of the lower gap concealing member is disposed below the seat cushion. Therefore, the connecting portion between the lower end of the lower gap concealing member and the moving member can be prevented from being seen from the rear of the vehicle, thereby improving the appearance of the gap concealing member.

[0021] The vehicle seat of a sixth aspect of the present invention is the vehicle seat of the fifth aspect, wherein an upper end of the upper gap concealing member is disposed forward of the vehicle rear end of the seat cushion.

[0022] In the vehicle seat of the sixth aspect of the present invention, the upper end of the upper gap concealing member is disposed forward of the vehicle relative to the vehicle rear end of the seat cushion, so that the upper gap concealing member extends downward toward the vehicle front in front of the vehicle rear end of the seat cushion. This makes it possible to prevent the gap between the upper end of the upper gap concealing member and the seat cushion from being visible due to the vehicle rear end of the seat cushion, so that the appearance of the gap concealing member can be further improved. In addition, the vertical position of the seat cushion can be adjusted without the upper gap concealing member protruding toward the vehicle rear from the vehicle seat.

[0023] A seventh aspect of the vehicle seat of the present invention is a first aspect in which the seat cushion is provided with a first support shaft into which the upper end portion of the upper gap concealing member is fitted to rotatably support the upper end portion of the upper gap concealing member.

[0024] In a vehicle seat according to a seventh aspect of the present invention, the seat cushion includes a first support shaft, and an upper end of the upper gap concealing member is fitted into the first support shaft, and the upper end of the upper gap concealing member is rotatably supported by the first support shaft. Therefore, the upper gap concealing member can be connected to the seat cushion with a simple configuration, which improves the ease of assembly when assembling the upper gap concealing member.

[0025] In the vehicle seat of the eighth aspect of the present invention, in the first aspect, the movable member is provided with a second support shaft into which the lower end portion of the lower gap concealing member is fitted to rotatably support the lower end portion of the lower gap concealing member.

[0026] In the vehicle seat of the eighth aspect of the present invention, the moving member includes a second support shaft, and the lower end of the bottom gap concealing member is fitted into the second support shaft, and the lower end of the bottom gap concealing member is rotatably supported by the second support shaft. Therefore, the bottom gap concealing member can be connected to the moving member with a simple configuration, and therefore the ease of assembly when assembling the bottom gap concealing member can be improved. Effect of the Invention

[0027] According to the vehicle seat of the first aspect of the present invention, it is possible to include a gap concealing member that can conceal the gap between the seat cushion and the rail without requiring space on the front side of the vehicle.

[0028] According to the second aspect of the vehicle seat of the present invention, the upper gap concealing member and the lower gap concealing member can expand and contract the length from the upper end of the gap concealing member to the lower end of the lower gap concealing member as the seat cushion moves up and down, even if there is no space on the front side of the vehicle.

[0029] According to the vehicle seat of the third aspect of the present invention, the upper gap concealing member and the lower gap concealing member are relatively movable by the sliding portion, and the extension / contraction trajectory of the gap concealing member can be set.

[0030] According to the vehicle seat of the fourth aspect of the present invention, the sliding portion is formed in accordance with the movement trajectory of the seat cushion when the vertical position of the seat cushion is adjusted, so that the vertical movement of the seat cushion can be permitted.

[0031] According to the vehicle seat of the fifth aspect of the present invention, the connecting portion between the lower end portion of the lower gap concealing member and the moving member can be prevented from being seen from the rear of the vehicle, thereby improving the appearance of the gap concealing member.

[0032] According to the vehicle seat of the sixth aspect of the present invention, the gap between the upper end of the upper gap concealing member and the seat cushion can be prevented from being seen by the vehicle rear end of the seat cushion, so that the appearance of the gap concealing member can be further improved.

The engagement portion 68 has a small diameter portion 68B that extends further in the vehicle width direction from the end face in the vehicle width direction of the large diameter portion 68A, and the small diameter portion 68B is formed in an elliptical column shape that is short in the vehicle front-rear direction when viewed from the vehicle width direction and is smaller than the large diameter portion 68A. The small diameter portion 68B is formed so that the thickness in the vehicle front-rear direction is slightly thinner than the length (width) in the short dimension direction of the sliding holes 74D and 76B.

[0061] The engaging portion 68 has a fastening portion 68C extending further in the vehicle width direction from the end surface in the vehicle width direction of the small diameter portion 68B, and the fastening portion 68C is formed in a rectangular column shape with a longer side in the vehicle front-rear direction when viewed in the vehicle width direction. Also, the fastening portion 68C is formed so that the thickness in the vehicle up-down direction is slightly thinner than the length (width) in the short direction of the slide holes 74D, 76B.

[0062] In this embodiment, the upper right end 64 and the upper left end 66 are defined as upper ends 60A of the upper shield 60.

[0063] Next, a method of assembling the upper shield 60 and the undershield 70 will be described. Figures 6 to 8 are explanatory views showing the steps of assembling the upper shield 60 and the undershield 70. In each figure, the symbol F indicates a person's finger.

[0064] First, as shown in Fig. 6, the fastening portion 68C of the engagement portion 68 on one side of the upper shield 60 (the right side in the vehicle width direction in this embodiment) is inserted into the slide hole 74D with the longitudinal direction of the fastening portion 68C being approximately aligned with the longitudinal direction of the slide hole 74D of the undershield 70. At this time, as shown in Fig. 6, the main body portion 62 of the upper shield 60 is raised approximately at a right angle to the main body portion 72 of the undershield 70.

[0065] Next, as shown in FIG. 7, with the longitudinal direction of the fastening portion 68C of the engagement portion 68 on the opposite side (in this embodiment, the left side in the vehicle width direction) approximately aligned with the longitudinal direction of the sliding hole 76B of the undershield 70, the fastening portion 68C is inserted into the sliding hole 76B.

[0066] 8, the upper shield 60 is tilted in the direction of arrow M in the figure so that the main body 62 of the upper shield 60 is approximately parallel to the main body 72 of the undershield 70. In a state in which the main body 62 of the upper shield 60 and the main body 72 of the undershield 70 are approximately parallel, the long dimension direction of the fastening portion 68C becomes approximately parallel to the width direction (short dimension direction) of the sliding holes 74D, 76B, and therefore the fastening portion 68C cannot come out of the sliding holes 74D, 76B.

[0067] As shown in Fig. 3, the upper shield 60 and undershield 70 assembled as described above, i.e., the shield 50, have support holes 64A and 66A (not shown in Fig. 3) in the upper end portion 60A of the upper shield 60 rotatably fitted to the second support rod 46B. Also, the undershield 70 has support holes 74B and 78A (not shown in Fig. 3) in the lower end portion 70B of the undershield 70 rotatably fitted to the first support rod 22C.

[0068] Since the first support rod 22C of the lower finisher 22 is disposed so as to be located forward of the vehicle relative to the second support rod 46B of the outer finisher 38, the shield 50 is disposed so as to incline downward toward the front of the vehicle in a side view. In addition, the engagement portions 68 of the upper shield 60 are configured to be movable along the slide holes 74D, 76B of the undershield 70, respectively. As a result, the upper shield 60 is connected to the undershield 70 so as to be movable relative to the undershield 70.

[0069] Next, the operation and effects of the first embodiment will be described.

[0070] In the front seat 10, the riser unit 18 is configured to be movable in the front-rear direction of the vehicle together with the upper rail 16. A seat cushion 10A is disposed above the upper rail 16, and the seat cushion 10A is connected to the riser 20 via a lifter mechanism 30. As a result, by moving the upper rail 16 in the front-rear direction of the vehicle, the position of the seat cushion 10A in the front-rear direction of the vehicle is adjusted, and the position of the seat cushion 10A in the up-down direction is adjusted by the lifter mechanism 30.

[0071] Furthermore, in the front seat 10, a shield 50 is provided between the upper rail 16 and the seat cushion 10A. As a result, the gap between the upper rail 16 and the seat cushion 10A is hidden by the shield 50. This prevents the gap between the seat cushion 10A and the upper rail 16 from being visually recognized, and also prevents the legs of an occupant seated in the rear seat of the vehicle from being pinched between the seat cushion 10A and the upper rail 16.

[0072] The seat cushion 10A is connected to the riser 20 via a lifter mechanism 30, and the vertical position of the seat cushion 10A is adjusted by the lifter mechanism 30. The support holes 64A, 66A of the upper end portion 60A of the upper shield 60 constituting the shield 50 are rotatably fitted to the second support rod 46B of the inner finisher 40, and the support holes 74B, 78A of the lower end portion 70B of the lower end portion 70B of the undershield 70 constituting the shield 50 are rotatably fitted to the first support rod 22C of the lower finisher 22. Therefore, when the vertical position of the seat cushion 10A is adjusted, the upper end portion 60A of the upper shield 60 and the lower end portion 70B of the undershield 70 are rotated in conjunction with the vertical movement of the seat cushion 10A.

[0073] Furthermore, the lower end 60B of the upper shield 60 and the upper end 70A of the undershield 70 move toward or away from each other in response to a change in the relative distance between the upper end 60A of the upper shield 60 and the lower end 70B of the undershield 70.

[0074] FIG. 9 shows a side view, partially cut away, seen from the right side of the vehicle, showing the seat cushion 10A positioned at its uppermost position; FIG. 10 shows a side view, partially cut away, seen from the right side of the vehicle, showing the seat cushion 10A positioned at its uppermost central position; and FIG. 11 shows a side view, partially cut away, seen from the right side of the vehicle, showing the seat cushion 10A positioned at its lowermost position.

[0075] 9, when the seat cushion 10A is positioned at the top in the up-down direction by the lifter mechanism 30, the engagement portion 68 of the upper shield 60 is positioned at the top end 70A side of the slide hole 74D of the undershield 70. Therefore, the distance between the upper end 60A of the upper shield 60 and the lower end 70B of the undershield 70 is the greatest. In this position, the distance from the upper end 60A of the upper shield 60 to the lower end 70B of the undershield 70 is the greatest in a substantially straight line.

[0076] On the other hand, when the seat cushion 10A is moved downward by the lifter mechanism 30 from the position shown in Fig. 9 to the middle portion in the up-down direction as shown in Fig. 10, the engagement portion 68 of the upper shield 60 moves in the direction of the arrow Y1 toward the lower end portion 70B of the undershield 70 in the sliding hole 74D, and is located in the middle portion of the sliding hole 74D. At the same time, the support hole 64A of the upper end portion 60A of the upper shield 60 rotates counterclockwise around the axis of the second support rod 46B, and the support hole 74B of the lower end portion 70B of the undershield 70 rotates counterclockwise around the axis of the first support rod 22C. In this position, the distance from the upper end portion 60A of the upper shield 60 to the lower end portion 70B of the undershield 70 is shorter than that in the state shown in Fig. 9. 9. Moreover, the shield 50 (the upper shield 60 and the under shield 70) swings so as to tilt downward further than the state shown in FIG. 9, since the upper end portion 60A of the upper shield 60 moves downward.

[0077] 10, when the seat cushion 10A is moved downward by the lifter mechanism 30 to the lowest position in the up-down direction as shown in FIG. 11, the engagement portion 68 of the upper shield 60 moves further in the direction of the arrow Y1 toward the lower end 70B of the undershield 70, and is positioned at the lowest end 70B side of the slide hole 74D. At the same time, the support hole 64A of the upper end 60A of the upper shield 60 rotates further counterclockwise around the axis of the second support rod 46B, and the support hole 74B of the lower end 70B of the undershield 70 rotates further counterclockwise around the axis of the first support rod 22C. At this position, the distance from the upper end 60A of the upper shield 60 to the lower end 70B of the undershield 70 becomes shorter than that in the state shown in FIG. 10, and the distance between the upper end 60A of the upper shield 60 and the lower end 70B of the undershield 70 becomes the closest. 10. Moreover, the upper end portion 60A of the upper shield 60 moves further downward, so that the shield 50 (the upper shield 60 and the under shield 70) swings so as to tilt further downward than the state shown in FIG.

[0078] Conversely, when the seat cushion 10A is moved upward by the lifter mechanism 30 from the position shown in Fig. 11 to the middle portion in the up-down direction as shown in Fig. 10, the engagement portion 68 of the upper shield 60 moves in the direction of arrow Y2 toward the lower end portion 70B of the undershield 70 in the sliding hole 74D, and is positioned in the middle portion of the sliding hole 74D. At the same time, the support hole 64A of the upper end portion 60A of the upper shield 60 rotates clockwise around the axis of the second support rod 46B, and the support hole 74B of the lower end portion 70B of the undershield 70 rotates clockwise around the axis of the first support rod 22C. In this position, the distance from the upper end portion 60A of the upper shield 60 to the lower end portion 70B of the undershield 70 is longer than in the state shown in Fig. 11. 9. Moreover, the shield 50 (the upper shield 60 and the under shield 70) swings so as to tilt upward from the state shown in FIG. 9, since the upper end portion 60A of the upper shield 60 moves upward.

[0079] 9, when the seat cushion 10A is moved upward by the lifter mechanism 30 from the position shown in FIG. 10 to the uppermost position in the up-down direction, the engagement portion 68 of the upper shield 60 moves further in the direction of the arrow Y2 toward the lower end 70B of the undershield 70, and is positioned on the uppermost end 70A side of the slide hole 74D. At the same time, the support hole 64A of the upper end 60A of the upper shield 60 rotates further clockwise around the axis of the second support rod 46B, and the support hole 74B of the lower end 70B of the undershield 70 rotates further clockwise around the axis of the first support rod 22C. At this position, the distance from the upper end 60A of the upper shield 60 to the lower end 70B of the undershield 70 becomes longer than in the state shown in FIG. 10, and the distance between the upper end 60A of the upper shield 60 and the lower end 70B of the undershield 70 becomes the largest. 10. Moreover, the upper end portion 60A of the upper shield 60 moves further upward, so that the shield 50 (the upper shield 60 and the under shield 70) swings so as to tilt further upward than the state shown in FIG.

[0080] In this way, the upper shield 60 and the undershield 70 are allowed to move (swing) following the movement of the seat cushion 10A, and the shield 50 swings in conjunction with the movement of the seat cushion 10A. At this time, the lower end 70B of the undershield 70 rotates with respect to the lower finisher 22 but does not move relatively in the front-rear direction of the vehicle. This allows the shield 50 to hide the gap between the seat cushion 10A and the upper rail 16 without requiring space on the front side of the vehicle.

[0081] In the front seat 10, the engagement portion 68 provided on the upper shield 60 is slidably engaged with the sliding holes 74D, 76B provided on the undershield 70. Therefore, the upper shield 60 and the undershield 70 are relatively movable by the sliding holes 74D, 76B, and the extension / contraction trajectory of the shield 50 is set.

[0082] Further, the slide holes 74D, 76B are provided extending along from the upper end 70A side to the lower end 70B side of the undershield 70. Therefore, the upper shield 60 and the undershield 70 are relatively movable along the slide holes 74D, 76B, and the extension / contraction trajectory of the shield 50 is set from the upper end 70A side to the lower end 70B side of the undershield 70. Here, by forming the slide holes 74D, 76B in accordance with the movement trajectory of the seat cushion 10A when the position of the seat cushion 10A in the up-down direction is adjusted, the seat cushion 10A is permitted to move in the up-down direction.

[0083] In addition, because the lower end 70B (support holes 74B, 78A) of the undershield 70 is disposed toward the front of the vehicle relative to the upper end 60A of the upper shield 60, the shield 50 extends downward toward the front of the vehicle, and the lower end 70B (support holes 74B, 78A) of the undershield 70 is disposed below the seat cushion 10A. This makes it possible to prevent the lower end 70B (support holes 74B, 78A) of the undershield 70 and the first support rod 22C of the lower finisher 22 from being visible from the rear of the vehicle, thereby improving the appearance of the shield 50.

[0084] Furthermore, as described above, since the upper end of the upper shield 60 is disposed in the vehicle forward direction with respect to the vehicle rear end of the seat cushion 10A, the upper shield 60 extends downward toward the vehicle front in front of the vehicle rear end of the seat cushion 10A. This makes it possible to prevent the gap between the upper end of the upper shield 60 and the seat cushion 10A from being visually recognized by the vehicle rear end of the seat cushion 10A, thereby further improving the appearance of the shield 50. Also, the position of the seat cushion 10A in the vertical direction can be adjusted without the upper shield 60 protruding from the front seat 10 toward the vehicle rear.

[0085] Furthermore, the first support rod 22C is provided in the lower finisher 22, and a notch 78B is provided in the support hole 78A of the lower end portion 70B of the undershield 70. Therefore, the support hole 74B is first fitted into the first support rod 22C, and then the first support rod 22C is fitted (fitted) through the notch 78B of the support hole 78A, thereby making it possible to rotatably assemble the support holes 74B and 78A of the undershield 70 to the first support rod 22C. This allows the undershield 70 to be connected to the riser unit 18 with a simple configuration. This improves the ease of assembly when assembling the undershield 70.

[0086] Further, the second support rod 46B is provided in the inner finisher 40, and the support hole 66A in the upper end portion 60A of the upper shield 60 is provided with a notch 66B. Therefore, the support hole 64A is first fitted with the second support rod 46B, and then the second support rod 46B is fitted (fitted) through the notch 66B of the support hole 66A, so that the support holes 64A, 66A of the upper shield 60 can be rotatably assembled to the second support rod 46B. Therefore, the upper shield 60 can be connected to the seat cushion 10A with a simple configuration. This improves the ease of assembly when assembling the upper shield 60.

[0087] Furthermore, the first support rod 22C is provided in the lower finisher 22, and the second support rod 46B is provided in the inner finisher 40. This makes it possible to provide the shield 50 to the front seat 10 using existing parts.

[0088] Further, both ends of the muscle portion 72B are connected to the right side wall 74 and the left side wall 76 of the undershield 70. The right side wall 74 and the left side wall 76 are connected by the muscle portion 72B, thereby increasing the rigidity of the right side wall 74 and the left side wall 76, and therefore it is possible to prevent the right side wall 74 and the left side wall 76 from being deformed or damaged when the small diameter portion 68B of the upper shield 60 slides through the sliding holes 74D, 76B.

[0089] In addition, ribs 74E, 76C extending in the up-down direction are formed on the end faces of the right side wall 74 and the left side wall 76 on the vehicle front side. The sides of the right side wall 74 and the left side wall 76 on which the ribs 74E, 76C are not formed (the vehicle rear side) are connected to each other by the main body portion 72, and therefore have high rigidity. In contrast, the sides on which the ribs 74E, 76C are formed (the vehicle front side) are not connected to each other by the main body portion 72, and therefore have lower rigidity than the sides on which the ribs 74E, 76C are not formed (the vehicle rear side). Therefore, by reinforcing with the ribs 74E, 76C as in this embodiment, the rigidity of the sides on which the ribs 74E, 76C of the right side wall 74 and the left side wall 76 are formed can be increased, and therefore, when the small diameter portion 68B of the upper shield 60 slides through the sliding holes 74D, 76B, the sides on which the ribs 74E, 76C of the right side wall 74 and the left side wall 76 are formed can be prevented from being deformed or damaged.

[0090] In addition, ribs 62C extending along the vehicle vertical direction are provided on the front end surface and rear end surface of the extension portion 62B of the upper shield 60 in the vehicle longitudinal direction. As a result, the extension portion 62B, which has a smaller width in the vehicle width direction than the main body portion 62, can be reinforced by the rib 62C. In addition, one end side of the rib 62C is formed so as to straddle the connection area between the main body portion 62 and the extension portion 62B. As a result, when the shield 50 is operated, it is possible to prevent the connection area from being deformed or damaged due to a load being concentrated on the connection area. In addition, the other end of the rib 62C is connected to the upper right end portion 64 and the upper left end portion 66, which are the rotation fulcrums of the second support rod 46B, respectively. As a result, it is possible to prevent the connection area from being deformed or damaged due to a load being concentrated on the connection area between the upper right end portion 64 and the upper left end portion 66 and the extension portion 62B during rotation.

[0091] (Modification) Next, a description will be given of a modified example of the upper shield 60. Fig. 12 is a perspective view showing an upper shield 80 which is a modified example of the upper shield 60. Note that in the modified upper shield 80, the same parts as those in the above-mentioned upper shield 60 are indicated by the same reference numerals and will not be described here, and only the different parts will be described in detail.

[0092] The upper shield 80 has an engagement portion 69 different from the engagement portion 68 of the upper shield 60 described above. The engagement portion 69 of the upper shield 80 does not have a small diameter portion 68B between the large diameter portion 68A and the fastening portion 68C. That is, the fastening portion 68C is directly provided on the end face of the large diameter portion 68A. The thickness of the large diameter portion 68A in the vehicle front-rear direction is made thinner than the length (width) of the slide holes 74D and 76B in the short length direction. In addition, a notch hole 62D is formed at the end portion on the left side of the vehicle of the main body portion 62, the tip of which is cut out in a semicircular shape from the end portion toward the inside. In addition, the muscle portion 62A1 extending in the vehicle width direction at the uppermost position of the muscle portion 62A extends longer in the vehicle width direction than the muscle portion 62A2 at the position of the notch hole 62D (the middle in this embodiment).

[0093] Even with such a configuration, the same effect as that of the above embodiment can be obtained. However, since the upper shield 60 of the above embodiment has the large diameter portion 68A and the fastening portion 68C on both sides of the small diameter portion 68B that slides through the slide holes 74D and 76B, the effect of suppressing rattling during sliding can be obtained. In addition, the muscle portion 62A1 that extends in the vehicle width direction at the uppermost side of the vehicle among the muscle portions 62A extends longer in the vehicle width direction than the muscle portion 62A2 at the position of the notch hole 62D (in the middle in this embodiment). Therefore, the muscle portion 62A1 can compensate for the reduction in rigidity of the main body portion 62 caused by forming the notch hole 62D. In addition, since the notch hole 62D is provided, the work can be performed by inserting a finger into the notch hole 62D during assembly, improving the ease of assembly.

[0094] Next, another modified example of the upper shield 60 and the undershield 70 will be described. Fig. 13 is a perspective view of the upper shield 90 and the undershield 100 assembled together. As shown in Fig. 13, the upper shield 90 and the undershield 100 of this modified example differ from the above-described embodiment in the structures of the muscle portions 92A, 92B, 102A, and 102B and the ribs 92C, 104E, and 106C.

[0095] The main body 62 of the upper shield 90 is provided with muscle portions 92A, five of which extend in the vertical direction, and muscle portions 92B, three of which extend in the vehicle width direction, for example. The muscle portions 92A are arranged close to each other, two by two, from the right side in the vehicle width direction, with one on the leftmost side. In this modified example, the number of muscle portions 92A is increased compared to the above-described embodiment, thereby improving rigidity. The method of arranging the muscle portions 92A and 92B is not particularly limited and can be changed as appropriate.

[0096] Moreover, the muscle portions 92A, 92B and the rib 92C of the upper shield 90 are higher in the vehicle front-rear direction than in the above-described embodiment. By increasing the height in this manner, the rigidity of the entire surface of the upper shield 90 can be improved.

[0097] Furthermore, the height of the muscle portions 102A, 102B and the ribs 104E, 106C of the undershield 100 in the vehicle front-rear direction is also greater than in the above-described embodiment. Increasing the height in this manner can improve the rigidity of the entire surface of the undershield 100.

[0098] In the above-described embodiments, the upper shield 60, 80, 90 is provided with the engagement portion 68, and the undershield 70, 100 is provided with the slide holes 74D, 76B, respectively, but the present invention is not limited to this. For example, the undershield 70, 100 may be provided with the engagement portion, and the upper shield 60, 80, 90 may be provided with the slide holes.

[0099] In the above embodiment, the sliding portion is a sliding hole, but the present invention is not limited to this. As long as it can be engaged with the engagement portion 68, for example, a sliding groove may be used.

[0100] Furthermore, in the above-described embodiment, the upper end portions 60A of the upper shields 60, 80, 90 are rotatably supported by the inner finisher 40, but the member supporting the upper end portions 60A is not limited to this. For example, the upper end portions 60A may be rotatably supported by the side frame 36A. In other words, it is only necessary that the upper end portions 60A of the upper shields 60, 80, 90 are supported by a member that rotates integrally with the seat cushion 10A.

[0101] Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and one embodiment may be appropriately combined with various modified examples, and the present invention may of course be embodied in various forms without departing from the gist of the present invention.
