Description

  The present invention relates to a sheet material moving mechanism for a vehicle.

  Conventionally, as a sheet material moving mechanism for a vehicle, for example, Patent Documents 1 to 3 are known. In Patent Document 1, the distance between the pair of rails extending along the longitudinal direction is set to be relatively larger than the length of the natural state of the sheet material, and the sliding members disposed at both ends of the sheet material are grooved in the rail. A technique to be fitted in is disclosed. Thereby, the tension | tensile_strength with respect to a sheet | seat material can be strengthened, and the sagging of a sheet | seat material can be suppressed.

  In Patent Document 2, a folding member in which both ends in the width direction of the sheet material are folded and overlapped is provided, and a wire member is loosely inserted therein, and the folding member in the rail member is prevented from falling off in the width direction. A technique in which a section is provided is disclosed. Thereby, an increase in sliding resistance due to variation in assembly of the sheet material can be suppressed.

  Patent Document 3 discloses a technique having a guide body connected to the lower surfaces of both side edge portions in the width direction of the sheet material, and a pair of guide portions having a guide space for receiving and guiding the guide body. Here, the guide portion is formed with an inclined surface portion that is located on the inner side in the sheet width direction adjacent to the guide body on the inner wall surface of the guide space and is inclined outward in the seat width direction toward the upper side. Thereby, the guide part can prevent the lack of tension in the width direction when the sheet material moves in the width direction during opening and closing movement.

  However, the material of the sheet material is variously selected, and there is a material with a large elongation rate of the sheet material, and there is a material that hardly obtains the elongation rate of the sheet material. In addition, some sheet materials expand and contract significantly due to environmental changes such as temperature and humidity. Therefore, it is assumed that it is difficult to keep the tension of the sheet material constant even when the dimensional accuracy at the time of manufacture and attachment is increased.

  Here, the technique of Patent Document 1 is capable of suppressing the sagging of the sheet when assembled, but the elongation rate of the sheet material, the expansion and contraction of the sheet when exceeding the expected expansion due to environmental changes. There is concern that it will not be possible to suppress the drooping. In addition, since the rail member is disposed directly on the ceiling material of the vehicle, the tension in the width direction of the sheet material is reduced due to variations in manufacturing dimensions in the seat device, variations in the mounting size of the sheet material, and the like. There is concern about the occurrence of Moreover, since the sliding member of patent document 1 is a structure which slides a rail member in the state to which tension | tensile_strength was given, when the tension | tensile_strength of the width direction of a sheet | seat material increases more than necessary, the sliding resistance of a sheet | seat material May increase and affect normal operation.

  Further, the technique of Patent Document 2 is configured such that the sliding resistance of the sheet material is difficult to increase, but on the other hand, when the tension in the width direction of the sheet material is reduced, the sheet material may be slack or wrinkled. There is.

  Moreover, the technique of the above-mentioned Patent Document 3 is such that the guide body and the inclined surface portion of the guide portion are in contact with each other in the case of dimensional variation at the time of manufacturing the sheet material, the elongation rate of the sheet material, and the elongation due to environmental changes. A state of not being able to occur. Therefore, when the sheet material moves in the width direction during the opening and closing movement, there is a concern that the structure that normally prevents the lack of tension does not work. For example, it may be noticeable when a material that hardly obtains the elongation rate of the sheet material is selected, the dimensional variation at the time of manufacture becomes large, and the guide body is not in contact with the inclined surface portion.

  The present invention was devised in view of such a point, and the problem to be solved by the present invention is to absorb a dimensional error during manufacture and installation in a sheet material moving mechanism for a vehicle, and a sheet.

<Embodiment 1>
Hereinafter, Embodiment 1 for carrying out the present invention will be described with reference to FIGS. A vehicle ceiling structure will be exemplified and described as Embodiment 1 of the present invention. In addition, the vertical, horizontal, and front / rear directions shown in the drawings as appropriate are shown in a unified manner in the vertical, horizontal, and front / rear directions around the vehicle. The following embodiments are also the same. As illustrated in FIG. 1, the vehicle ceiling structure according to the first embodiment includes a roof panel 12 (vehicle component) in a vehicle 10 (vehicle) and a vehicle ceiling material disposed on the vehicle interior side of the roof panel 12. 20 (trim member). The opening / closing mechanism 30 (sheet material moving mechanism) is assembled along the surface of the vehicle ceiling material 20 facing the roof panel 12.

  The roof panel 12 (vehicle constituent member) is made of a steel plate as the roof of the vehicle 10 as shown in FIG. The roof panel 12 has a sunroof opening 14 formed therein. In addition, the opening part 14 is not restricted to the aspect for sunroofs, There also exists the aspect of the glass roof which inserted the transparent glass etc. in the opening part 14 concerned. On the vehicle interior side of the roof panel 12, a vehicle ceiling material 20 is mounted as an interior material.

  The vehicle ceiling material 20 (trim member) is assembled so as to face the vehicle interior side of the roof panel 12. As shown in FIGS. 1 and 2, the vehicle ceiling material 20 is formed by laminating a base material 24 and a skin material 26 and integrating them by heat fusion, an adhesive, or the like. The base material 24 is a part responsible for maintaining the shape of the vehicle ceiling material 20, ensuring rigidity, sound absorption in the vehicle interior, heat insulation, and the like.

  The base material 24 is formed by laminating a fiber reinforcing material such as a glass fiber coated or impregnated with a thermosetting adhesive on both surfaces of a core material such as a urethane foam of a semi-hard layer made of a urethane resin foam, and a non-back surface. The aspect by which the backing material which consists of a breathable film, a thermoplastic synthetic fiber nonwoven fabric, etc. is laminated | stacked is illustrated. The core material is provided in order to maintain the shape and ensure the rigidity, and may adopt an aspect having sound absorption and heat insulation in the vehicle interior. The core material can be applied in various ways such as corrugated cardboard, urethane, and foamed olefin. As the fiber reinforcing material, glass fiber, basalt fiber, jute, kenaf, ramie, hemp, sisal, bamboo and the like can be applied. Further, as the fiber-based base material 24, a fiber mat having the above-described fiber reinforcing material and thermoplastic synthetic resin can also be applied.

  The skin material 26 is a part that bears the design surface of the vehicle ceiling material 20. The skin material 26 is laminated with a surface layer, a urethane foam sheet, and the like. The surface layer can be applied to various fabrics such as fabric, cloth, knit, cloth members such as woven fabric, non-woven fabric, and raised fabric, synthetic leather, artificial leather, and genuine leather. The urethane foam sheet is laminated by applying a soft layer made of a urethane resin foam to the vehicle ceiling material 20 in order to obtain a soft tactile sensation. In addition, the skin material 26 can also apply the aspect in which a urethane foam sheet is not laminated | stacked. In addition, about the structure of the ceiling material 20 for vehicles, various said materials can be applied variously.

  The vehicle ceiling material 20 has a surface shape and an outer shape corresponding to the roof panel 12 of the vehicle 10. The vehicle ceiling material 20 is set to have a low basis weight in order to meet the demand for weight reduction. That is, when the vehicle ceiling material 20 is lifted in a temporarily assembled state in which the vehicle ceiling material 20 is attached to the vehicle ceiling material 20 alone, the vehicle ceiling material 20 may be bent by its own weight due to insufficient rigidity, but may be broken. In the assembled state, the minimum necessary basis weight having rigidity is set.

  As shown in FIGS. 1 and 2, various types of vehicle equipment such as a sun visor and an assist grip are mounted on the roof panel 12 of the vehicle 10 via a vehicle ceiling material 20. Accordingly, the vehicle ceiling member 20 is formed with a plurality of holes (not shown) that are formed so as to penetrate the vehicle ceiling parts corresponding to the respective arrangement parts of the vehicle equipment. The roof panel 12 has mounting holes (not shown) described later corresponding to the holes of the vehicle ceiling material 20. The vehicle equipment is inserted into the hole of the vehicle ceiling member 20 and attached to each mounting hole of the roof panel 12 by fixing means such as bolts, nuts, screws, clips and the like. Accordingly, the vehicle ceiling material 20 is attached to the roof panel 12. Further, a sunroof opening 22 is formed in a substantially central portion of the vehicle ceiling material 20 by penetrating in the thickness direction. The periphery of the opening 22 for the sunroof is a portion where the area of the vehicle ceiling material 20 is small and the cross-sectional secondary moment is low.

  As described above, in the vehicle ceiling material 20, as shown in FIGS. 1 and 2, the periphery of the opening 22 of the vehicle ceiling material 20 facing the roof panel 12 is a portion having a low cross-sectional second moment. Therefore, the reinforcing member 50 is disposed along the opening 22. The reinforcing member 50 is a flat and strip-shaped member made of synthetic resin. The reinforcing member 50 is disposed along at least the vehicle front-rear direction in the periphery of the sunroof opening 22 in the vehicle ceiling material 20. The reinforcing member 50 is fixed by bonding a plurality of portions in the longitudinal direction with a hot melt adhesive or the like.

  As the reinforcing member 50, various cross-sectional shapes can be applied as long as the rigidity of the vehicle ceiling material 20 is compensated for. Further, the fixing of the reinforcing member 50 to the vehicle ceiling material is not limited to the hot melt adhesive, and various fixing means can be applied. Here, the length of the reinforcing member 50 in the longitudinal direction (vehicle longitudinal direction) is disposed in a pair of left and right along the edge in the width direction of the opening 22 (disposed along the periphery of the opening 22). In view of this, it is desirable that the opening 22 is longer than one side in the vehicle front-rear direction. In addition, it is necessary to make the structure thinner than the gap between the roof panel 12 and the vehicle ceiling material 20. The length of the reinforcing member 50 in the short direction (vehicle width direction) can be variously applied as long as it does not interfere with the opening 22 and the vehicle body structure. The material of the reinforcing member 50 is made of a lightweight material such as an appropriate synthetic resin or aluminum alloy. In the present embodiment, the reinforcing member 50 is selected from synthetic resin. As the synthetic resin of the reinforcing member 50, for example, a known thermoplastic member such as polypropylene resin, polyethylene resin, acrylonitrile / butadiene / styrene (ABS) resin can be applied. Further, in order to improve the strength, a fiber reinforcing material may be mixed with the synthetic resin. As a fiber reinforcement, for example, natural fibers such as glass fibers, basalt fibers, etc., organic fibers such as jute (barley), kenaf (marine), ramie, hemp (hemp), sisal, bamboo, etc. are appropriately selected. it can.

The sheet material 32 is a member formed into a planar shape by a flexible material, such as fabric, cloth, knit, etc., woven fabric, non-woven fabric, raised cloth, etc., synthetic leather, artificial leather, genuine leather, etc. Various materials can be applied. Moreover, the aspect which laminates | stacks a urethane foam sheet etc. may be sufficient. The sheet material 32 is desirably configured to be thinner than an opening width 44a (see FIG. 5) of a groove 44 described later.

  As shown in FIGS. 3 to 5, guide structures 40 are provided in the vicinity of both ends in the width direction intersecting the moving direction of the sheet material 32. The guide structure 40 includes a convex portion 62 (guide body) projecting in the thickness direction of the sheet material 32 and a guide rail 41 described later. A plurality of the convex portions 62 are arranged adjacent to each other with a predetermined interval along the longitudinal direction of the sheet material 32. The convex part 62 is a part that is inserted into the cylindrical part 42 (guide part) of the guide rail 41 and slides. The protrusion 62 can be applied in various ways such as metal and synthetic resin. The convex part 62 has a thickness 62 a that can be inserted inward of a cylindrical part 42 in the guide rail 41 to be described later and can slide in the longitudinal direction, and is larger than the opening width 44 a of the groove part 44. In addition, the convex part 62 and the sheet | seat material 32 are the aspects fixed integrally, and can take various fixing methods, such as sewing, welding, and caulking. In addition, the convex part 62 may be arrange | positioned continuously along the longitudinal direction. Moreover, the convex part 62 may be an aspect in which the end part of the sheet material 32 is wound and stitched.

  The guide rails 41 are arranged in parallel at the outer periphery of the sheet material 32 and are arranged in parallel so that the sheet material 32 is stretched, and the closed position 30A (first position) and the open position 30B are arranged along the surface direction. It is a member that guides movably between (second positions). The guide rail 41 is made of a lightweight material such as a synthetic resin or an aluminum alloy. In this embodiment, the guide rail 41 is made of synthetic resin. Here, as the synthetic resin of the guide rail 41, for example, a thermoplastic resin such as polyvinyl chloride (PVC), polyacetal (POM), polyamide (PA), polypropylene (PP), polyethylene terephthalate (PET) can be applied. . It is desirable to have flexibility. The guide rail 41 includes a cylindrical portion 42 (guide portion) as viewed in a cross section orthogonal to the longitudinal direction and a groove portion 44 that is open in a part of the circumferential direction of the tubular portion 42 and continues along the longitudinal direction. Yes. Further, on the side opposite to the groove portion 44, there is a flat plate-like connecting portion 46 that extends linearly outward in the radial direction and continues continuously in the longitudinal direction of the guide rail 41. Further, the connecting portion 46 has a protruding portion 48 that protrudes in the thickness direction of the sheet material 32. The overhanging portion 48 has an overhanging dimension 48 a that is inserted inward of a holding portion 72 in a support 70 to be described later and is larger than the opening width 74 a of the retaining portion 74. Here, as for the guide rail 41, the cylindrical part 42 and the connection part 46 are integrally comprised with the thermoplastic resin. On the other hand, the overhang portion 48 is configured as a thermoplastic elastomer. The cylindrical portion 42, the connecting portion 46, and the overhang portion 48 are formed by two-color extrusion molding. The overhang portion 48 is a material that can be elastically deformed. Further, the protruding portion 48 has a fin-like portion protruding in the vertical direction of the connecting portion 46 of the guide rail 41. Such a fin-like portion is curved and elastically deformed. Therefore, the overhang portion 48 functions as a tension applying mechanism that applies tension in the width direction to the sheet material 32 by urging an elastic force in the width direction of the sheet material 32. And the guide rail 41 becomes a structure supported by the support body 70 via the overhang | projection part 48 as a tension | tensile_strength provision mechanism. Note that the guide rail 41 may be configured such that the integral structure of the tubular portion 42 and the connecting portion 46 and the overhang portion 48 are connected together by bonding or the like.

  The support body 70 is a part that supports the guide rail 41 and is connected to the reinforcing member 50. The support 70 is made of a metal material such as a synthetic resin or an aluminum alloy. In the present embodiment, a synthetic resin is selected for the support 70. Here, as the synthetic resin of the support 70, for example, a thermoplastic resin such as polyvinyl chloride (PVC), polyacetal (POM), polyamide (PA), polypropylene (PP), polyethylene terephthalate (PET) can be applied. . The support body 70 has a holding portion 72 that is formed in a cylindrical shape and holds the overhang portion 48 of the guide rail 41, and a retaining portion 74 that engages so that the overhang portion 48 does not come out of the holding portion 72. doing. The support body 70 is intermittently spaced apart in the moving direction of the sheet material 32. Note that the support body 70 may be configured to continuously continue in the moving direction of the sheet material 32.

  A pair of left and right guide rails 41 are disposed along the edge in the width direction of the opening 22 (disposed along the periphery of the opening 22). And the support body 70 accommodates the overhang | projection part 48 of the guide rail 41 inside the holding | maintenance part 72, and is comprised integrally by the reinforcement member 50 and adhesion | attachment. In addition, the extension direction of the connection part 46 is not limited to the above-mentioned aspect, It can extend in various directions. Moreover, the connection part 46 is not restricted to the structure which continues in a row in the longitudinal direction, It may be comprised in multiple places at intervals. The reinforcing member 50 and the support body 70 in the present embodiment are configured separately from each other, and any of an aspect in which these are connected and integrated, or an aspect in which they are integrally formed in advance can be applied.

  The winding device 34 is disposed on one side around the opening 22. In the present embodiment, the winding device 34 exemplifies a mode in which the winding device 34 is disposed on one side of the vehicle rear side around the opening 22. The winding device 34 is a device that can be switched between a state in which the sheet material 32 is pulled out and deployed, and a state in which the sheet material 32 is wound up and stored. In the opening / closing mechanism 30, the state in which the sheet material 32 is pulled out and deployed is the closed position 30A (first position), and the state in which the sheet material 32 is wound up and stored is the open position 30B (second position). Become. The winding device 34 mainly includes a roll member 35, a support member 36, an elastic member (not shown), and a front bar 38.

  The roll member 35 is configured as a shaft-like member having a length of one side of the opening 22, is fixed to one end in the drawing direction of the sheet material 32, and winds the sheet material 32 by rotating around the axis. It is a member. The support member 36 is a member that is disposed at both ends of the roll member 35 and supports the roll member 35 so as to be rotatable around the axis. An elastic member (not shown) is a member that is interposed between the support member 36 and the roll member 35 and exerts an elastic biasing force in the winding direction (open position 30B) with respect to the roll member 35. The front bar 38 is fixed along the other end of the sheet material 32 in the pulling direction (corresponding to the leading end of the sheet material 32 in the pulling direction), and is moved between the guide rails 41 described later to move the sheet material 32. Keep it stretched in the direction. The front bar 38 is made of a metal material such as a synthetic resin or an aluminum alloy. The front bar 38 in the present embodiment employs an aluminum alloy in order to suppress thermal expansion and contraction.

  The guide rail 41 of the guide structure 40 is supported by the support body 70 via the overhanging portion 48 as a tension applying mechanism that applies tension in the width direction to the sheet material 32. Here, the overhang portion 48 is made of a thermoplastic elastomer which is a material that can be elastically deformed. The protruding portion 48 has a fin-shaped portion protruding in the vertical direction of the connecting portion 46 of the guide rail 41. Such a fin-like portion is bent and elastically deformed to apply tension to the sheet material 32 outward in the width direction. Therefore, the overhang portion 48 is elastically deformed in a range between the position indicated by the phantom line in FIG. 5 and the position indicated by the solid line. The overhanging portion 48 constantly urges the elastic force toward the outer side in the width direction of the sheet material 32, thereby suppressing a decrease in the tension of the sheet material 32 and preventing the sheet material 32 from being bent or wrinkled. The sheet material 32 may be variously adopted such as a material having a high elongation rate, a material in which the elongation rate of the sheet material is hardly obtained, and there may be a material in which expansion and contraction occurs due to changes in the environment such as temperature and humidity. Here, since the guide mechanism 40 of the opening / closing mechanism 30 (sheet material moving mechanism) is supported by the support body 70 via the overhanging portion 48 as a tension applying mechanism by the overhanging portion 48, at the time of manufacturing and mounting. This dimensional error can be absorbed by the elastic deformation of the overhanging portion 48 to keep the tension of the sheet material constant.

  Thus, according to the opening / closing mechanism 30 (sheet material moving mechanism) according to the embodiment, the guide structure 40 opens from the closed position 30A (first position) along the surface direction in a state where the sheet material 32 is stretched. The guide is movably guided between the positions 30B (second position). Here, the guide structure 40 has a configuration of a convex portion 62 (guide body) and a guide rail 41. On the other hand, the guide rail 41 is supported by the support body 70 via an overhang portion 48 as a tension applying mechanism that applies tension in the width direction to the sheet material 32. Thereby, the dimensional error at the time of manufacture and attachment of the sheet material 32 can be absorbed.

Can be arranged.

<Ninth Embodiment>
Next, Embodiment 9 will be described with reference to FIGS. The ninth embodiment has a function of returning the guide rail to the normal position on the assumption that a large force is applied to the sheet material and the guide rail is dropped from the support.

  A front bar 938 is connected to the leading end (front end) of the sheet material 932 in the pull-out direction. Shoes 939 (sliding members) are set on both ends of the front bar 938. The shoe 939 includes a fitting portion 939a, a surrounding portion 939b, and a sliding piece 939d. The fitting part 939a is a part into which the front bar 938 is fitted. The enclosure portion 939 b is a portion that holds the cylindrical portion 42 of the guide rail 41 from the outer peripheral side and is close to the position where the mouth portion 939 c is along the connecting portion 46. The sliding piece 939d is a portion that extends downward from the surface on the vehicle ceiling material 20 side of the enclosure portion 939b and engages with the reinforcing member 950 to slide. The reinforcing member 950 has a fixing portion 952 that fits the attachment piece 976 of the support body 970 and prevents the support body 970 from coming off in the thickness direction. Further, the reinforcing member 950 is continuously provided with a sliding groove 954 that receives and slides the sliding piece 939d from the width direction.

  The leading end of the sheet material 932 (the front side terminal, in other words, the position of the front bar 938) is partially cut off at both ends in the width direction, the convex portion 62 does not exist, and the guide rail 41 Since the engagement with the cylindrical portion 42 is not performed, a load in the width direction is not exerted on the guide rail 41. Therefore, since the tension from the sheet material 932 is suppressed at the leading end of the sheet material 932 in the pulling direction, the elastic deformation of the overhang portion 48 as a tension applying mechanism is small. The sheet material 32 can be moved between the closed position 30A (first position) and the open position 30B (second position) by directly gripping the front bar 938 and moving it in the vehicle longitudinal direction. Alternatively, a pulling member such as a pull wire may be connected to the shoe 939, and the sheet material 32 may be moved to the closed position 30A by pulling the pull wire.

The front bar 938 has improved dimensional stability by using an extruded material such as an aluminum alloy. In addition, the sliding groove 954 of the reinforcing member 950 provides a tolerance absorbing margin for absorbing a mounting dimension tolerance for attaching the reinforcing member 950 to the vehicular ceiling member 20, thereby stably sliding the sliding piece 939d of the shoe 939. Can be moved. Note that the reinforcing member 950 is an aspect having the sliding groove 954 and thus is provided in a single-sheet configuration that is continuous in the vehicle front-rear direction. Alternatively, a plurality of reinforcing members 950 can be intermittently disposed by separately setting a single-sliding groove component.

  The shoe 939 has a function of suppressing rattling in the thickness direction when the sheet material 32 is moved. Further, the shoe 939 has a function of returning the support body 970 to the normal support state when the guide rail 41 is detached from the support body 970. The leading end (front side terminal) of the sheet material 932 has the guide rail 41 inserted from the outer peripheral side by the surrounding portion 939b of the shoe 939 even when a large force is applied to the sheet material 932. It cannot be removed from the support 970. On the other hand, in a portion other than the leading end (front end) of the sheet material 932, the guide rail 41 may be detached from the support body 970 when a greater force than expected is applied to the sheet material 932 (for example, in the lower part of FIG. 13). Guide rail 41 in support 970). Even if the guide rail 41 is disengaged from the support body 970, when the shoe 939 is moved to the disengaged position, the guide rail 41 holding the shoe is pushed into a predetermined position in the support body 970 and returned. That is, as shown in FIG. 16, the protruding portion 48 is pushed into the support body 970 while the mouth portion 939 c of the shoe 939 holds the cylindrical portion 42 of the guide rail 41.

<Embodiment 10>

The sliding groove 1054 is provided closer to the opening 22 than the support 1070 in the reinforcing member 1050. The sliding groove 1054 projects vertically from the base surface of the reinforcing member 1050 toward the roof panel 12 and is provided with a groove in the width direction. Since the reinforcing member 1050 has a sliding groove 1054, the reinforcing member 1050 is provided in a single sheet configuration that is continuous in the vehicle front-rear direction. Alternatively, the sliding groove 1054 may be provided on the guide rail 1041 (which is continuous in the front-rear direction). In this case, a plurality of reinforcing members 1050 can be intermittently arranged.

As for the guide rail 1041, the cylindrical part 1042, the groove part 1044, and the overhang | projection part 1048 are integrally shape | molded by the extrusion molding of a synthetic resin.

  As described above, the guide rail 1041 receives the holding portion 1072 of the support body 1070 from the thickness direction in the cutout portion 1049a of the overhang portion 1048. Further, the guide rail 1041 is prevented from coming off in the thickness direction by the engaging portion 1049b of the overhanging portion 1048 engaging with the retaining portion 1074 of the support 1074. Further, the guide rail 1041 is given a tension in the width direction with respect to the sheet material 32 by the leaf spring 1077 of the support 1070. With the above configuration, the overhanging portion 1048 of the guide rail 1041 has a fitting structure in which the support member 1070 is prevented from coming off from both the width direction and the thickness direction of the sheet material 1032.

  The overhanging portion 1048 of the guide rail 1041 is prevented from coming off from the width direction and the thickness direction of the sheet material 1032 with respect to the support body 1070. On the other hand, the overhanging portion 1048 and the leaf spring 1077 as a tension applying mechanism apply tension to the sheet material 1032 in the width direction. As a result, the guide rail 1041 is prevented from coming off from the support 1070, and tension is applied to the sheet material 1032 by the overhanging portion 1048 serving as a tension applying mechanism and the leaf spring 1077. That is, the guide rail 1041 can prevent the sheet material 1032 from being bent and wrinkled while being prevented from falling off the support 1070.
