Summary of the Invention

Problems to be Solved by the Invention

[0004] When the seat back is tilted forward and the fin part hits a structure inside the seat back and is pushed forward, the fin part is likely to be warped in a shape that is rolled forward. As a result, a problem occurs in that the structure inside the seat back is exposed from the warped part of the fin part. Therefore, the present invention provides a seat side shield capable of preventing the fin part from being rolled up forward as the seat back is tilted forward.

Means for Solving the Problems

[0005] As a means for solving the above problems, the seat side shield of the present invention takes the following means. That is, the first invention of the present invention is a base side side shield provided so as to cover a base frame to which a seat back is hinged so as to be able to fall forward from the front, and a back side side shield provided on the seat back so as to cover the base side side shield from the front. A seat side shield having a flap portion provided with flexibility to avoid interference with the contact portion by bending although it contacts the contact portion of the base side side shield due to the forward fall of the seat back, and the contact portion is provided with a guide surface for guiding the flap portion that is applied by the forward fall of the seat back into the seat back as the seat back falls forward. It is a seat side shield.

[0006] According to the first invention, the flap portion is guided by the guide surface of the contact portion so as to be drawn into the seat back as the seat back falls forward by contacting the contact portion due to the forward fall of the seat back. As a result, it is possible to prevent the flap portion from being rolled up forward as the seat back falls forward.

[0007] The second invention of the present invention is the seat side shield according to the first invention, wherein the contact portion is a protrusion that partially protrudes from the base side side shield.

[0008] According to the second invention, while appropriately covering the base frame from the front with the base side side shield, a contact portion having a guide surface for guiding the flap portion to be applied by the forward fall of the seat back and drawn into the seat back can be appropriately provided on the base side side shield.

[0009] The third invention of the present invention is the seat side shield according to the first or second invention, wherein the guide surface is formed in a guiding shape that bends in a winding shape so as to apply the flap portion that is applied by the forward fall of the seat back to the side surface of the base side side shield as the seat back falls forward and slides backward along the side surface.

[0010] According to the third invention, the guide surface having the above shape can guide the flange portion to be appropriately drawn into the seat back as the seat back tilts forward.

Mode for Carrying Out the Invention

[0012] Hereinafter, modes for carrying out the present invention will be described with reference to the drawings.

[0013] 《First Embodiment》 <Configuration of Seat Side Shield S> First, the configuration of the seat side shield S according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 7. In the following description, when indicating directions such as front, rear, up, down, left, and right, the respective directions shown in each figure shall be referred to. Further, in the following description, when no specific reference figure is shown, or when there is no reference numeral corresponding to the reference figure, any one of FIGS. 1 to 7 shall be appropriately referred to.

[0014] As shown in FIG. 1, the seat side shield S according to the present embodiment is applied to a rear seat 1 that forms a rear seat of an automobile. The rear seat 1 is configured as a so-called bench seat that can accommodate three people in the same row. Specifically, the rear seat 1 includes a horizontally long seat back 2 that forms a backrest portion and a horizontally long seat cushion 3 that forms a seating portion.

[0015] Both the seat back 2 and the seat cushion 3 are fixed to a vehicle body (not shown). The seat back 2 is configured to be divided into three parts: a seat back 2R that forms the backrest portion of the right seat, a seat back 2C that forms the backrest portion of the center seat, and a seat back 2L that forms the backrest portion of the left seat. The division ratio in the seat width direction (left - right direction) of the seat back 2R of the right seat, the seat back 2C of the center seat, and the seat back 2L of the left seat is 4:2:4.

[0016] The seat backs 2R of the right seat and 2L of the left seat are each connected to the vehicle body at their lower end portions on both left and right sides so that the reclining angle can be adjusted by a recliner (not shown). The seat back 2C of the center seat is connected to the vehicle body at its lower end portions on both left and right sides by support pins PR and PL, which will be described later with reference to FIG. 2, so that it can be folded forward independently leaving the other seat backs 2R and 2L.

[0017] Also, as shown in FIG. 1, although not shown in the drawing, the seat back 2C of the center seat is configured such that its reclining backward is restricted at a position side - by - side with the seat back 2R of the right seat by a support structure provided in the seat back 2R of the right seat. With the above configuration, the seat back 2C can be switched between a position where it is used as a backrest side - by - side with the seat back 2R of the right seat and a position where it is folded forward onto the upper surface of the seat cushion 3 and used as an armrest.

[0018] Specifically, as shown in FIG. 2, the seat back 2C of the center seat is connected to a support frame F fixed on the floor of a vehicle (not shown). The support frame F includes a tubular support pipe FP extending in the seat width direction in the region directly below the seat back 2C, and two plate-shaped support brackets FR and FL joined to two positions on the left and right sides of the support pipe FP.

[0019] The right support bracket FR is a bracket whose right side surface is connected to a recliner (not shown) on the left side of the right seat back 2R. A plate-shaped attachment bracket FRa that bends in a crank shape when viewed from the front is joined to the left side surface of the right support bracket FR. The attachment bracket FRa is joined to the right support bracket FR in a direction where the crank rises upward to the left.

[0020] A support pin PR is joined to the plate portion at the tip of the attachment bracket FRa that rises upward to the left so as to extend leftward from this plate portion. Further, a support pin PL is joined to the left support bracket FL so as to extend rightward from the portion where the support bracket FL rises. The seat back 2C of the center seat is hinge-connected to the support frame F such that the support pins PR and PL are inserted through the lower end portions on both the left and right sides thereof, and can rotate with respect to the support frame F. The support pins PR and PL are arranged such that positions on the same axis extend in the seat width direction.

[0021] As shown in FIGS. 3 to 4, resin seat side shields S are provided at the lower end portions on both the left and right sides of the seat back 2C of the center seat to cover these hinge-connected portions from the outside. As shown in FIG. 3, the seat side shield S has a left base side shield 10L provided to cover the left support bracket FL from the front. Here, the left support bracket FL corresponds to the "base frame" of the present invention.

[0022] Also, as shown in FIG. 4, the seat side shield S has a right back side side shield 20R provided on the right side portion of the seat back 2C so as to cover the right support bracket FR from the front. Further, the seat side shield S has a left back side side shield 20L provided on the left side portion of the seat back 2C so as to cover the left support bracket FL and the base side side shield 10L from the front.

[0023] The right back side side shield 20R is configured not to interfere with the right support bracket FR and the attached bracket FRa even when the seat back 2C of the center seat is tilted forward. The reason is that the right back side side shield 20R enters backward through the gap in the height direction between the attached bracket FRa bent in a crank shape described above in FIG. 2 and the support pipe FP as the seat back 2C of the center seat tilts forward.

[0024] On the other hand, as shown in FIG. 4, the left back side side shield 20L is configured to interfere with the left base side side shield 10L when the seat back 2C of the center seat is tilted forward. The reason is that as shown in FIG. 2, the left support bracket FL is shaped to rise straight upward from the support pipe FP and is located on the movement locus of the left back side side shield 20L shown in FIG. 4.

[0025] That is, as shown in FIG. 3, since the left base side side shield 10L is provided so as to cover the left support bracket FL from the front and the left side along the shape of the left support bracket FL, it is configured to interfere with the left back side side shield 20L. Therefore, as shown in FIGS. 4 to 6, the portion of the left back side side shield 20L that covers the left base side side shield 10L from the front is formed by a rubber fin portion 22 having flexibility capable of avoiding interference with the base side side shield 10L by bending.

[0026] Specifically, the left back side shield 20L has a resin shield body 21 fixed to the seat back 2C and a rubber fin portion 22 extending in a projecting manner from the shield body 21. The shield body 21 is generally in the shape of an L-shaped plate covering the left side portion and the front side portion of the seat back 2C. Specifically, the portion of the shield body 21 covering the front side portion of the seat back 2C is formed in a reverse L-shaped form in a front view with the lower right corner cut out, leaving its upper portion and left edge. And the fin portion 22 is provided so as to project into the portion cut out in the reverse L-shaped form of the shield body 21 in a front view.

[0027] The fin portion 22 is formed in a vertically long strip shape that covers the left base side shield 10L from the front. The entire left edge and upper edge of the fin portion 22 are joined and integrated with the periphery of the portion cut out in the reverse L-shaped form of the shield body 21 in a front view. The right edge and lower edge of the fin portion 22 are configured as free ends that are not joined to other members such as the shield body 21. Thereby, the fin portion 22 is configured such that it can bend the other parts like the deflection of a cantilever beam with the left edge and upper edge joined to the shield body 21 as a fulcrum.

[0028] On the other hand, as shown in FIGS. 5 to 6, the left base side shield 10L has a shield body 11 shaped so as to be able to cover the left support bracket FL from the front and both the left and right sides. Further, the left base side shield 10L is configured such that a contact portion 12 is formed at a portion that contacts the fin portion 22 when the seat back 2C of the center seat tilts forward, and the contact portion 12 guides the fin portion 22 into the seat back 2C by contact. The contact portion 12 is formed so as to project angularly forward from a part of the front surface portion covering the support bracket FL of the shield body 11 from the front.

[0029] When the contact portion 12 abuts against the flange portion 22 due to the forward tilting of the seat back 2C, it has an inclined guide surface 12A that guides the flange portion 22 to be drawn into the seat back 2C together with the forward tilting of the seat back 2C. As shown in FIG. 5, when the seat back 2C is in the position where it is used as a backrest (the position before forward tilting), the contact portion 12 is spaced apart and located below and behind the lower edge of the flange portion 22.

[0030] The left end portion of the lower edge of the flange portion 22 is shaped such that it partially extends rearward and downward in a long shape in a region that deviates to the left from the contact portion 12. Thereby, in a state where the seat back 2C is in the position where it is used as a backrest, the flange portion 22 extends rearward and downward longer than the contact portion 12 while avoiding interference with the contact portion 12, and is shaped to be able to cover the base side side shield 10L more widely from the front.

[0031] As shown in FIG. 6, when the seat back 2C is tilted forward, the lower edge of the flange portion 22 abuts against the guide surface 12A that forms the upper surface of the protruding shape of the contact portion 12. As shown in FIG. 7, the guide surface 12A is formed to form a rib-shaped constricted surface that continuously extends obliquely downward to the rear along the left side surface of the shield main body 11 from the portion that forms the upper surface of the protruding shape of the contact portion 12. Due to the guide surface 12A, as shown in FIG. 6, the contact portion 12 can draw in the lower edge of the flange portion 22 that has abutted with the forward tilting of the seat back 2C while deflecting it upward in the drawing so as to escape to the left side surface of the shield main body 11 without directly hitting the front surface of the shield main body 11.

[0032] Specifically, the contact portion 12 deflects the lower edge of the flange portion 22 that has abutted with the forward tilting of the seat back 2C so as to be wound inward (the direction of drawing into the seat back 2C: upward in the drawing) along the guide shape of the guide surface 12A with the left edge coupled to the shield main body 21 as a fulcrum. As a result, the flange portion 22 is wound so as to be drawn into the seat back 2C along the guide surface 12A in order from its lower edge as the seat back 2C tilts forward.

[0033] Then, the fin portion 22 drawn into the interior of the seat back 2C slides rearward along the guide surface 12A on the left side surface of the shield body 11 while remaining in the shape wound along the guide surface 12A. For this reason, even when the seat back 2C is tilted forward, the fin portion 22 is prevented from being rolled up forward from the seat back 2C due to contact with the base side side shield 10L.

[0034] Therefore, an excessive load that pushes the fin portion 22 forward against its elastic force is not applied. Further, plastic deformation due to such an excessive load does not occur in the shield body 11 that supports the fin portion 22. Accordingly, the shield body 11 is not deformed into a shape that opens outward, and the fin portion 22 is not warped forward, so that the internal structure of the seat back 2C is not visible from the outside.

[0035] As a result, even when the fin portion 22 deteriorates due to long-term use, it is likely to be warped so as to be rolled into the inside of the seat back 2C rather than forward. Therefore, even when the fin portion 22 is used for a long time, the fin portion 22 can appropriately cover the hinge connection portion of the seat back 2C from the front and maintain a state in which the internal structure of the seat back 2C is not easily visible from the outside.

[0036] Summarizing the above, the seat side shield S according to the present embodiment has the following configuration. In the following, the reference numerals in parentheses correspond to the respective configurations shown in the above embodiment.

[0037] That is, the seat side shield (S) includes a base side side shield (10L) provided to cover the base frame (FL) to which the seat back (2C) is hinged so as to be able to fall forward from the front, and a back side side shield (20L) provided on the seat back (2C) to cover the base side side shield (10L) from the front. The back side side shield (20L) includes a flexible fin portion (22) that contacts the contact portion (12) of the base side side shield (10L) due to the forward fall of the seat back (2C) and avoids interference with the contact portion (12) by bending. The contact portion (12) has a guide surface (12A) for guiding the fin portion (22) that is applied by the forward fall of the seat back (2C) into the interior of the seat back (2C) as the seat back (2C) falls forward.

[0038] According to the above configuration, the fin portion (22) contacts the contact portion (12) due to the forward fall of the seat back (2C), and is guided by the guide surface (12A) of the contact portion (12) to be drawn into the interior of the seat back (2C) as the seat back (2C) falls forward. As a result, it is possible to prevent the fin portion (22) from being rolled up forward as the seat back (2C) falls forward.

[0039] Further, the contact portion (12) is a protrusion that partially protrudes from the base side side shield (10L). According to the above configuration, while the base side side shield (10L) appropriately covers the base frame (FL) from the front, the contact portion (12) having the guide surface (12A) for guiding the fin portion (22) into the interior of the seat back (2C) by applying the fin portion (22) due to the forward fall of the seat back (2C) can be appropriately provided on the base side side shield (10L).

[0040] Further, the guide surface (12A) is formed into a guiding shape that deflects in a winding manner so as to bring the fin portion (22) that is applied by the forward fall of the seat back (2C) into contact with the side surface of the base side side shield (10L) as the seat back (2C) falls forward, and slides rearward along the side surface. According to the above configuration, the guide surface (12A) having the above shape can guide the fin portion (22) to be appropriately drawn into the seat back (2C) as the seat back (2C) falls forward.

[0041] 《Regarding Other Embodiments》 As described above, the embodiments of the present invention have been described using one embodiment. However, the present invention can be implemented in various forms shown below in addition to the above embodiments.

[0042] 1. The seat side shield of the present invention can be applied not only to the seats of automobiles but also to the seats of vehicles other than automobiles such as railways, and to the seats of vehicles other than vehicles such as airplanes and ships. Further, the seat side shield can be applied not only to vehicles but also to seats other than vehicles such as viewing seats and massage seats installed in various facilities such as sports facilities, theaters, concert halls, and event venues.

[0043] 2. The contact portion of the base side side shield does not necessarily have to be formed of a protrusion that partially protrudes from the base side side shield. That is, the contact portion may have a configuration formed of a surface portion that is flush with the peripheral portion of the base side side shield or a recessed portion that is recessed with respect to the peripheral portion.

[0044] The guide surface of the contact portion only needs to be formed in a shape that guides the fin portion into the seat back. In addition to being in surface contact with the fin portion, it may be in linear or point contact to guide the movement. Further, the guide surface may be formed of a curved surface or a stepped surface in addition to an inclined surface.

[0045] 3. The base frame covered by the base side shield from the front may be any frame to which the seat back is hingedly connected so as to be able to fall forward. That is, the base frame may be composed of a component member (support bracket) of the support frame fixed on the floor, or a frame (such as a reclining plate rising from the lower arm) connected to the frame of the seat cushion to which the seat back is hingedly connected so as to be able to fall forward with respect to the seat cushion, when the seat back is configured to be hingedly connected to the seat cushion.
