Description

The present invention relates to a blindfold structure of an anchor used for attaching a child seat to a seat for an automobile or other vehicle.

FIG. 6 is a perspective view showing a configuration of a mechanism for detachably attaching a child seat to a vehicle seat (see, for example, Patent Document 1). As shown in FIG. 6, the child seat mounting mechanism 100 has a rear portion in which an anchor 103 having a substantially inverted U-shape in a plan view, which is projected from the surface of the seat cushion 102 of the vehicle seat 101, serves as a blind spot in the figure of the child seat 104. The child seat 104 is positioned and fixed on the seat cushion 102 by locking the checking provided on the seat cushion 102.

Further, as shown in the enlarged view of the main part of FIG. 7, the lower end portion 103a of the anchor 103 is joined to the frame 106 in the seat cushion 102 by welding or the like, and is opened in the trim (skin material) 108 of the seat cushion 102. Where the upper end 103b protrudes through the slit 108a, the structures inside the seat cushion 102 such as the pads 102b and 102c are exposed to the outside from the slit S, which impairs the aesthetic appearance or the checking slits when the child seat 104 is attached or detached. Problems such as being caught in the 108a and impairing the operability of attachment / detachment occur.

In response to such a problem, Patent Document 1 discloses a technique in which a trim piece that passes between anchors 103 and covers the slit 108a is provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 corresponds to an enlarged view of the region R shown in FIG. 6, and is a plan view showing a configuration of a vehicle seat including a blindfold structure 1 of a child seat mounting anchor according to an embodiment of the present invention. , FIG. 1 is a cross-sectional view of a main part taken along the line AA of FIG. However, the same or equivalent configurations as those of the conventional examples shown in FIGS. 6 and 7 are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in each figure, the blind structure 1 of the child seat mounting anchor includes an anchor 10 that projects outward through a slit S formed on a skin material 102a that covers the surface of the seat cushion 102 of the vehicle seat. The frame 20 which is arranged inside the seat cushion 102 and extends along the vehicle width direction to form the skeleton of the vehicle seat, and the shielding member 30 which covers the slit S are provided as the main configurations.

The seat cushion 102 is the same as the conventional seat cushion, and houses the frame 20 and the pads 102b and 102c inside. Further, the pads 102b and 102c are arranged in the front-rear direction in the vehicle length direction with the frame 20 sandwiched between them, and form a gap in which the anchor 10 is arranged.

The anchor 10 is made of a metal having a substantially inverted U-shape in a plan view, in which a pair of strut portions 10a and a crossover portion 10b provided so as to connect between the pair of strut portions 10a are integrally formed. It is a member of. One of the two ends of the pair of support columns 10a is joined to the surface of the frame 20 by fillet welding, and the other of the two ends is curved or bent from the welding position with the frame 20 to form a gap between the pads 102b and 102c. It has an aspect of extending toward the surface, projecting onto the skin material 102a through the slit S, and then connecting to the crossover portion 10b.

The shielding member 30 is a sheet-like member having a substantially arrow-shaped plane shape formed by laminating a resin film on a non-woven fabric. The shielding member 30 locks a planar rectangular main body 30a having a width substantially matching the facing distance between the pair of support columns 10a of the anchor 10 and a planar triangular isosceles triangle located at the end of the main body 30a. It is divided into parts 30b. The configuration of the shielding member 30 will be described in detail later.

Further, on the skin material 102a, the slit S is a planar rectangular void including the side edges 102a1 and 102a2 in the longitudinal direction corresponding to the entire width of the anchor 10 including the widths of the pair of support columns 10a. is there. A side edge 102a1 located forward in the vehicle length direction is sewn to the tip of the main body 30a of the shielding member 30, whereby the skin material 102a and the shielding member 30 are integrated in the sheet assembly process described later. Treated in.

Next, FIG. 3 is a perspective view taken by arrow B in FIG. 2, and FIG. 4 is a perspective view taken by arrow C in FIG. 2, in which the display of the skin material 102a and the pads 102b and 102c is omitted. It is a figure which shows each shape and arrangement relation of a frame 20 and a shielding member 30. As described above, the pair of support columns 10a of the anchor 10 and the frame 20 are joined by fillet welding, so that the end faces 10a1 of the pair of support columns 10a are approximately normal to the surface of the frame 20. It is exposed to the outside along the direction.

The shielding member 30 extends downward while being curved along the side surface of the frame 20 in a state where the main body portion 30a is arranged in the gap 10x of the pair of support columns 10a of the anchor 10, and each of the pair of support columns 10a. It is connected to the locking portion 30b at a position corresponding to the end surface 10a1 of. The locking portion 30b forms a pair of locking ends 30E whose contours are substantially orthogonal to the extending direction of the main body 30a and whose width direction is larger than that of the main body 30a, and further extends from the locking ends 30E. As the widthwise dimension of the protruding portion becomes smaller toward the end of the shielding member 30, the overall shape is a substantially isosceles triangular planar shape. Further, the shielding member 30 has a certain rigidity in the surface direction and a certain flexibility in the perpendicular direction of the surface. Therefore, as shown in FIG. 2, it is easy to be deformed along the curved surface of the frame 20, but in the plane direction shown in FIGS. 3 and 4, it is easy to maintain the stereotype that maintains the planar shape of the substantially arrow shape.

In the above configuration, the skin material 102a corresponds to the skin material of the present invention, and the slit S corresponds to the slit of the present invention. Further, the anchor 10 corresponds to a structure located inside the skin material of the sheet of the present invention, the pair of support columns 10a corresponds to a plurality of columns of the present invention, and the shielding member 30 corresponds to the shielding member of the present invention. However, the locking portion 30b of the shielding member 30 corresponds to one end of the shielding member of the present invention.

The child seat mounting anchor blindfold structure 1 according to the embodiment of the present invention as described above has the above-described configuration, so that the shielding member 30 can be sewn together with the skin material 102a and the main body 30a. By locking the locking end 30E of the locking portion 30b to the end surface 10a1 of the support column portion 10a of the anchor 10, the posture of the shielding member 30 is restricted, and the main body portion 30a can be easily positioned at a position where the slit S is shielded. It becomes possible to position.

Hereinafter, a further description will be given with reference to FIG. FIG. 5 is a diagram showing an assembly process of the seat cushion 102. As shown in the figure, the seat cushion 102 is completed by covering the seat body portion to which the pads 102b and 102c, the frame 20 and the anchor 10 are assembled with the skin material 102a from the direction of the white arrow in the figure. .. At this time, the gap 10x formed by the pair of support columns 10a of the anchor 10 is formed by the locking portion 30b of the shielding member 30 whose main body 30a is sewn to the side edge 102a1 of the slit S (not displayed as a blind spot in the drawing). And insert it into the gap C formed by the pads 102b and 102c and the frame 20.

As a result, the locking portion 30b bends inward and moves downward in the gap 10x in the vehicle length direction, and when the locking end 30E reaches the end surface 10a1 of the support column portion 10a, the shape is restored and the locking end 30E is restored. Locked to the end face 10a1, movement in the insertion direction is restricted and positioned.
