Description

  The present invention relates to a structure provided with a groove for drawing a skin material covering a pad material in a pad material of a seat used for a vehicle such as an automobile.

  The surface of the pad material provided on the seating surface or backrest surface of an automobile seat is generally not flat and various shapes are provided. Especially in the part where the direction of the surface of the pad material is switched, a recess called a groove is formed along the boundary, and by providing means for drawing the skin material into this groove, the skin material is firmly aligned with the pad material, Conventionally, the skin material is given tension. In general, a method is provided in which a wire is provided on each of the pad material forming the bottom of the groove and the back side of the skin material, and the wires are bundled with a ring at several locations so that the skin material is drawn.

  In addition, an electrical component that spreads in a planar shape may be sandwiched between the pad and the skin, such as a heater for heating the seat surface and the backrest surface, and a sensor for detecting the seating of the occupant. When the surface of the pad is divided into several sections by grooves, heaters and sensors are provided over a plurality of sections as necessary. However, since a wire runs in the groove and cannot be covered with a heater or a sensor, it is necessary to provide a heater or a sensor of a size corresponding to each section of the pad and connect with a wiring crossing the groove.

  In the pad for a sheet described in Patent Document 1 below, two horizontal grooves extending in the sheet width direction are connected to left and right vertical grooves, and the surface of the pad is completely divided into three sections arranged in the front-rear direction. ing. And the part where the wiring material of the heater crosses in the lateral groove is penetrated to the back side of the pad, and it is large while preventing the interference with the wire on the skin material side by letting the wiring material hang deep into this through hole. The curvature is secured. Further, the wire on the pad side for drawing the skin material is diverted to the side of the groove in the section where the wiring material crosses, thereby preventing the wire and the wiring material from interfering with each other. However, it takes time to immerse the wiring material deeply into the grooves and holes. Moreover, if the redundant part of the wiring material is long, the material cost is increased accordingly.

  Patent Document 2 describes a planar body including a heater and a sensor. This planar body is formed by connecting rectangular portions respectively arranged on the front and rear pad sections with narrow left and right bridging portions. This is used for pads where the wire is not provided over the entire length of the transverse groove and there is a portion where the wire does not pass through the transverse groove. By arranging the left and right bridging portions in a portion where the wire does not pass, it is possible to prevent the wiring of the heater and the sensor from interfering with the wire. However, in the part where the wire does not pass, the skin material cannot be tensioned, and the appearance of the sheet is deteriorated.

  The present invention has been made in view of such problems, and the problem to be solved by the present invention is to draw the skin material into the groove even if the wiring member is arranged so as to cross the groove of the pad material. This is to make it difficult for the wiring to be interfered by the means, and to prevent the conductor from being disconnected.

  In order to solve the above problems, the present invention takes the following means. The skin material retracting structure obtained from one aspect of the present invention has a cushioning pad material provided on the seat cushion or seat back of a vehicle seat, and the surface of the pad material is covered with a sheet-like skin material. Yes. A groove for drawing the skin material is formed on the surface of the pad material, a linear member runs in the groove, the linear member is held by the drawing member extending from the skin material into the groove, and the linear member is at least 2 Moored at the bottom of the groove at a point. A wiring member for an electric appliance provided between the skin material and the pad material is arranged so as to cross the groove passing between the linear member and the pad material. The linear member passes through a position where the groove is shallower in a section where the wiring member crosses than the portion where the linear member is moored.

  As one aspect, the same shape of pad material can be used regardless of the presence or absence of the wiring member by making the groove shape the same at the location where the linear member is moored and the section where the wiring member crosses. good.

  Further, as one aspect, the pull-in member is formed of a cylindrical cloth whose passage is narrowed in a section where the wiring member crosses, and the pull-in member is held by passing the linear member through the cloth passage. May be. The linear member is made of a material that can bend or bend with elasticity, so that when it is moored at the bottom of the groove, the pulling member can be tensioned by the restoring force even in the section where the wiring member crosses. May be.

  Moreover, as one aspect, even if a belt-like cloth having a narrow portion in the middle is folded back at the center of the width and the overlapping edges are stitched together into a cylindrical shape to form a narrowed portion in the middle of the passage good. The end of the pad material side is pulled away from the bottom of the groove in the section where the passage is narrowed by sewing the end of the seam side of the cylindrical cloth to the skin material and extending the end of the crease side linearly .

  As another aspect, the belt-like cloth is folded at the center of the width, the edges of the width are stitched together into a cylindrical shape to form a substantially constant passage, and a seam is added to the edge on the crease side. A narrowed portion may be formed in the middle of the passage.

  Also, as one aspect, the base wire is fixed to the bottom of the groove of the pad material, the linear member is moored to the base wire, and the base wire is padded in the section where the wiring member extends beyond the location where the linear member is moored. You may make it pass near the inside of a material. For example, the base wire may be simply bent so that the base wire is exposed in the groove at the place where the linear member is anchored, and the base wire is buried in the pad material in the section where the wiring member crosses.

  As another aspect, the pulling member is formed of a strip-like cloth whose width is narrowed in the middle, and the wiring member is crossed by fixing the linear member along one edge of the width of the cloth. The linear member may warp in the section and pass through a shallow portion of the groove. The linear member may be formed of resin and integrally formed on the cloth. Furthermore, by sewing the end of the belt-like cloth on the skin material side to the skin material and extending the end of the skin material side in a straight line, the end on the pad material side is away from the bottom of the groove in the section where the passage is narrowed You may make it attract.

  Even if the wire member is moored at the bottom of the groove, the wire member is not easily interfered by the wire member because the wire member runs in a shallow position in the section where the wire member crosses, and disconnection is unlikely to occur. Become. In addition, the skin material can be drawn uniformly over the entire length of the groove regardless of whether the wiring member is crossed, and the skin material cannot be wrinkled even in the zone where the wiring member crosses, so that the appearance of the skin material is improved.

It is a figure which shows the state which passed the linear member through the drawing member of FIG. 10, and was sewn on the skin material. As another embodiment of the present invention, it is a diagram showing a retracting member constituted by fixing a linear member to the edge of a belt-like cloth whose width is narrowed in the middle. FIG. 13 is a view showing a state in which the drawing member of FIG. 12 is sewn to the skin material and the linear member is warped.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the part which exhibits a substantially equivalent function in several Example, and detailed description is not repeated.

  The pad material is attached to a seat frame (not shown) to form a seat cushion seat surface for receiving an occupant and a seat back back surface. The seat is preferably provided on a vehicle such as an automobile or a railway vehicle. FIG. 1 shows a pad material 10 provided on a seat cushion of an automobile seat as an example. The pad material 10 is formed of a generally used cushioning material such as polyurethane foam. As shown in FIG. 3, the surface of the pad material 10 is covered with a skin material 30 for providing a design and a tactile sensation.

  A groove 12 for drawing the skin material 30 is formed on the upper surface of the pad material 10. As one embodiment, as shown in FIG. 1, left and right vertical grooves extending in the depth direction of the sheet and horizontal grooves extending in the sheet width direction so as to connect these can be provided. As described above, the surface of the pad material 10 is divided into several sections by the grooves 12.

  As shown in FIG. 3, a linear member 50 is provided in the groove 12 along the direction of the groove. The linear member 50 can be constituted by, for example, a simple metal wire or a resin rod. The linear member 50 is held by some means on a drawing member 40 provided so as to extend from the skin material 30 into the groove 12. As an example, using a cloth such as a cotton cloth as shown in FIG. 3, the passage 110 in the cylinder is arranged in a direction parallel to the direction of the groove 12, and the upper end is sewn to the skin material 30. By passing the linear member 50 through the passage 110, it can be held by the retracting member 40.

  The linear member 50 is anchored to the bottom of the groove 12 in at least two places. If the dimensions of the pull-in member 40 are set appropriately, the skin member 30 can be pulled by applying tension to the pull-in member 40 by mooring the linear member 50. As a means for mooring the linear member, various known methods can be used. As an example, a base wire 60 is fixed to the bottom of the groove 12 of the pad material 10 as shown in FIG. The shaped member can be anchored to the base wire 60 with a ring 70. FIG. 3 shows a state before the C-shaped ring 70 is closed. The base wire 60 can be fixed to the pad material 10 by being partially embedded in the pad material 10 by integral molding with the pad material 10. As shown in FIGS. 3 and 4, the base wire 60 can be easily exposed by providing a shallow hole 16 over the bottom of the groove 12 where the linear member is anchored.

  As shown in FIGS. 4 and 5, an electric appliance 20 that spreads in a planar shape is sandwiched between the skin material 30 and the pad material 10. The planar electric appliance includes a heater that warms the seat for a seated occupant, a sensor that detects that the occupant is seated on the seat, and the like. Such an electric appliance is arrange | positioned, for example in the range shown with a dashed line in FIG. The main part 22 of the heater or sensor is arranged for each section of the surface of the pad material 10 divided by the groove 12, but these parts 22 are arranged in a plurality of sections and connected by the wiring member 24 across the groove 12. Is done. Two or more wiring members may be passed to one groove, but it is desirable to anchor the linear members on both sides of each wiring member 24.

  The wiring member 24 includes a conductor and may function as a heat generating member of the heater, but may be an electric wiring itself such as a covered conductor for constituting a circuit. As an example, the conductor 26 may be fixed to a base material as shown in FIG. For example, a non-woven fabric is used as the base material, and the conductive wire 26 is fixed thereto by sewing 28 or the like, whereby the wiring member 24 having a belt-like shape as a whole can be obtained. Moreover, it is good to fix the conducting wire 26 to a base material so that stress may not be applied when a base material bends.

  As shown in FIG. 3, the wiring member 24 of the electric appliance is disposed so as to pass between the linear member 50 and the pad material 10. Since the wiring member 24 passes through a deeper position of the groove 12 than the linear member, the linear member cannot be anchored to the bottom of the groove in the section where the wiring member 24 crosses the groove, but the linear member and the drawing member It is possible to apply tension to the skin material 30 via 40.

  As shown in FIGS. 4 and 5, the linear member 50 runs in a shallow position in the groove in a section where the wiring member 24 crosses than a portion moored at the bottom of the groove 12. Even if the linear member is moored at the bottom of the groove 12, if the linear member runs in a shallow position of the groove 12 in the section where the wiring member 24 crosses, the wiring member 24 is less likely to be interfered by the linear member, Disconnection is less likely to occur. Further, the skin material 30 can be drawn almost uniformly over the entire length of the groove 12 without being affected by the wiring member 24 crossing the groove 12, and the appearance of the skin material 30 is improved. In order to obtain such a structure, the linear member 50 may be formed in a curved shape in advance, but a linear member having elasticity may be bent by some means.

  As one means, as shown in FIG. 3, the pulling member 40 can be formed of a cylindrical cloth in which the passage 110 is narrowed in the section where the wiring member 24 crosses. In a portion where the passage is constricted (narrowed), even if the linear member 50 is pulled toward the bottom of the groove 12, it cannot reach the deep position of the groove and remains at a relatively shallow position. The linear member 50 is formed of a material and a form that can bend and bend with elasticity, so that even if the linear member 50 cannot be moored, the linear member 50 exerts tension on the pulling member 40 due to the force that the linear member tries to restore. You may be able to do that. As the linear member 50, for example, a metal wire formed so as to be linear in a natural state may be used. When the linear member is moored by the ring 70, a hole can be made in a part of the cloth as shown in FIG.

  As an example, as shown in FIG. 6 to FIG. 8, the belt-like cloth 100 having a narrow portion in the middle is folded back at the center of the width, and the overlapping ends 104 are sewn together into a cylindrical shape. A narrowed portion 112 can be formed in the middle of the passage 110. As shown in FIG. 7, the cylindrical cloth has a concave end 104 on the seam 108 side and a straight end 106 on the crease side, but it is preferable to sew the end 204 on the concave side to the skin material (the seam). 42). The end 104 on the side of the seam 108 that has been recessed is extended linearly as shown in FIG. 8 by the tension of the skin material, and conversely, the end 106 on the side of the crease that has been linear is drawn away from the bottom of the groove 12. The linear member is warped in the passage 110 and passes through the shallow portion of the groove 12. Since the edges bent in an arc shape are sewn to a flat skin material, it is preferable to use a cotton cloth with sparse fibers.

  As an example, as shown in FIG. 3, a hook-like portion 52 is provided at one or both ends of a linear member 50 so that it can be hooked on both ends of a tubular cloth, The shape member may be made difficult to shift. In particular, when the hook-shaped portion 52 is thicker than the other portions, after the linear member 50 is once passed through the narrowed portion 112 of the passage 110 during assembly, the hook-shaped portion is caught and the drawing member It becomes difficult to fall out of 40.

  As shown in FIG. 3, the base wire may pass closer to the inside of the pad material 10 in a section where the wiring member 24 crosses than a place where the linear member 50 is moored. For example, using a base wire 60 that has been bent in advance, the base wire is exposed in the groove 12 at a position where the linear member 50 is moored, and the base wire is buried in the pad material 10 in a section where the wiring member crosses. Good. Thereby, since the base wire is separated from the linear member in the section where the wiring member crosses, the wiring member is unlikely to interfere with the base wire, and disconnection can be further prevented.

  In the section where the wiring member 24 crosses, the linear member 50 passes through a shallow position and does not get in the way, so there is no need to provide a hole for bypassing the wiring member 24 by further rolling the bottom of the groove 12 or the like. As an example, as shown in FIGS. 4 and 5, the depth of the groove 12a in the section where the wiring member 24 crosses is substantially equal to the depth of the groove 12b in the place where the linear member 50 is anchored ( By making it the same (except for the shallow hole 16 for exposing the base wire 60), it is possible to use the pad material 10 in a common form regardless of whether it is a sheet with a heater or sensor specification.

  A portion having a narrow passage can be formed without using a cloth having a narrow portion in advance as shown in FIG. As shown in FIG. 10 and FIG. 11, a belt-like cloth having a substantially constant width is folded back at the center of the width, and both ends 104 of the width are stitched together (with seams 108) to form a cylindrical shape. A narrowed portion 112 may be formed in the middle of the passage by forming the passage 110 and inserting an arc-shaped seam 114 at the end of the crease. As a result, it is possible to deal with both the specification of passing the wiring member 24 to the groove 12 and the specification of not passing it by simply changing the presence or absence of the seam 114.

  Further, the pull-in member 40 can be configured without using a cylindrical cloth as shown in FIGS. As another embodiment, as shown in FIG. 13, the pull-in member 40 is constituted by a belt-like cloth 200 having a portion 202 narrowed in the middle, and the linear member 50 is formed along one end 206 of the width of the cloth. By fixing the wire member, the linear member can pass through the shallow portion of the groove 12 in the section where the wiring member 24 crosses. The linear member 50 may be integrally formed at the end of the cloth 200 as a resin rod.

  In particular, using a cloth 200 in which one end 204 of the width is recessed and the other end 206 is linear, and a resin rod molded so as to be linear in a natural state, A resin rod is integrally formed, and the recessed end 204 is sewn to the skin material. The recessed end 204 is linearly extended as shown in FIG. 13 by the tension of the skin material, and the linear end 206 is pulled away from the bottom of the groove 12 to be recessed, and the linear member 50 is warped. Through the shallow part of the groove.

  In addition, this invention is not limited to the Example demonstrated above, It can implement with the form which added the other various substitution, improvement, and a change.
