  It is another object of the present invention to provide a steering wheel cover with excellent aesthetics, in which it is difficult for the driver to visually recognize the back edge when mounted on a steering wheel.

  In order to solve the problems as described above, the measures taken by the present invention are as follows. The best mode for carrying out the “automotive steering wheel cover” of the present invention will be described. In addition, the term used in this specification and a claim is used with the following meaning. “Ring” indicates the shape of the entire wheel of the steering wheel cover for automobiles, “circumference” indicates this ring-shaped circumference, and “center” indicates the center of this circumference, that is, The ring-shaped center of the steering wheel cover is shown. The “vertical cross section” indicates a cut surface when cut along the diameter of the ring, for example, the AA cross section of FIG. 2 represented by AA of FIG. `` Front '' and `` back '' mean that the driver side is `` front '' and the vehicle display panel side is `` back '', assuming that the automobile steering wheel cover of the present invention is attached to the steering wheel. In FIG. 3, the side of the visible side is the front side.

  The vehicle steering hole cover according to claim 1 of the present invention is formed in a ring shape having an opening along the circumference, and the ring-shaped circumferential cross section is an annular shape having an opening. The circumferential length of one opening end side and the other opening end side forming both ends of the opening is different from each other, and the steering wheel cover for an automobile is characterized.

  By adopting such a structure, if the opening end on the long circumferential side is the back side and the opening end side on the short circumferential side is the front side, it is fitted into the steering wheel for an automobile, and the back side has a long circumference. So it will be easier to fit. In addition, since the front side is a short circumferential side, the opening end side on the back side cannot be visually recognized by the driver, so that the aesthetics when fitted into the steering wheel cover for an automobile are improved.

  According to a second aspect of the present invention, there is provided a vehicle steering wheel cover having a distance from a center of a ring-shaped circumference to the one opening end and a distance from the other opening end. It is characterized by being different

  By adopting such a configuration, if the opening end with a long distance from the center is on the back side and the opening end on the circumferential side with a short distance from the center is on the near side, it can be fitted into the steering wheel for an automobile. Since the distance from the center is long, the side is easy to fit. In addition, since the front side is short from the short center, the opening end on the back side cannot be visually recognized by the driver, so that the aesthetics when fitted into the steering wheel cover for an automobile are improved.

  The means taken by the automobile steering wheel cover according to claim 3 of the present invention is further characterized in that the vertical section is formed by combining arcs having different radii.

  By adopting such a configuration, an automobile steering wheel cover in which the circumferential lengths of one opening edge and the other opening edge forming the both ends of the opening are different, and the center of the ring-shaped circumference To the one opening edge side and the distance to the other opening edge side can be a vehicle steering wheel cover.

  The vehicle steering wheel cover according to claim 4 of the present invention is characterized in that at least one open end side of the vertical section is further bent inward.

  By adopting such a configuration, it is attached to the steering wheel cover for automobiles with the open end side pressed, so that it is possible to provide a steering wheel cover for automobiles that can be easily fitted but is not easily removed.

  According to a fifth aspect of the present invention, there is provided the vehicle steering wheel cover according to the fifth aspect of the present invention, wherein the arc has a small radius with respect to the other portion in the vicinity of at least one open end of the vertical section. It is what.

  By adopting such a configuration, similarly, since the opening end side is pressed against the automobile steering wheel cover, the automobile steering wheel cover can be easily fitted but not easily detached.

  The means taken by the automobile steering wheel cover according to claim 6 of the present invention is further characterized in that it has a straight portion in at least a part of the vertical section.

  By adopting such a configuration, it is possible to attach to a steering wheel for an automobile having various cross sections.

  The effects obtained by adopting the above means are as follows.

  According to the automobile steering wheel cover of the present invention, it is possible to provide a steering wheel cover that is difficult to come off, although it can be easily attached to the steering wheel.

  In addition, when the driver sits in the driver's seat and looks at the steering wheel cover for an automobile while attached to the steering wheel, the opening end on the back side is hidden by the opening end on the near side, so The edge of the opening is not exposed, and the appearance can be improved.

  The automotive steering wheel cover according to the present invention is formed in a ring shape having an opening so as to be attached to the steering wheel as a whole. The circumferential length of the ring is appropriately selected according to the size of the steering wheel to be attached. It does not necessarily have to be the same as the circumference of the steering wheel. For example, if the material of the steering wheel cover for an automobile is made of rubber, urethane or the like having high elasticity, the steering wheel can be extended and attached. It may have a shorter circumference.

  The vertical cross section is formed in an annular shape and has an opening in a part thereof. The annular shape does not necessarily have an arc shape at the circumference, and may be, for example, a C shape, an elliptical shape, or a combination of arcs having various Rs as long as the shape surrounds the steering wheel as a whole. May be. The opening is not simply a part of a circle, but is formed so that the lengths of the ring-shaped circumferences of the two opening edges forming the opening are different. That is, the distance from the center of the opening end side is different (the lengths of B and C in FIG. 1 are different). Therefore, the opening edge having a short circumference has a shorter distance from the center than the opening edge having a long circumference. For example, as shown in FIG. 3, an automobile from the opening edge side having a short circumference is used. When looking at the steering wheel cover, the long opening edge on the opposite side cannot be seen. Therefore, the aesthetics when viewed from the driver's seat when attached to the steering wheel are improved.

  When attaching to the steering wheel for automobiles, it is attached while being fitted into the steering wheel cover for automobiles from the side having the long opening end side, that is, the longer distance from the center. Therefore, since the circumference of the opening end side is longer than the conventional one, the rate of extending the end side is small, and it can be easily fitted with a small force.

  In addition, when forming a vertical cross section so that it may have the length of a different opening edge side, you may form a vertical cross section combining an arc with a different radius. For example, as shown in FIG. 2, in the vertical cross section, the lengths of the two circumferential end sides forming the opening are different by forming the radius of the arc of the portion α and the portion γ different from each other. It can be. In particular, for example, referring to FIG. 2, the vicinity δ (that is, the end arranged on the back side when attached to the automobile steering wheel) is adjacent to the vicinity of the long opening edge fitted into the automobile steering wheel. By forming it so as to bend inward from the arc (γ part) or to reduce the radius of the arc, the vicinity of the opening edge δ is pressed against the steering wheel. It becomes possible to make it difficult to remove the steering wheel cover for automobiles. Further, it is possible to prevent a gap from being generated between the steering wheel and the steering wheel cover.

  Further, in accordance with the shape of the steering wheel, a portion that is not an arc may be provided in the middle. For example, a straight portion may be provided in part as shown by the portion β in FIG.

FIG. 2 is a cross-sectional view taken along the line AA of the steering wheel cover 100 of FIG. FIG. 3 shows a state in which the automobile steering wheel cover 100 according to the first embodiment is attached to the automobile steering wheel.

  The steering wheel cover 100 according to the first embodiment is formed in a ring shape as a whole. The cross section is provided in an annular shape with a part open, and includes a stretchable base layer 10, a cushion layer 20, and a surface layer 30 from the inside. The base layer 10 is made of EPDM and has appropriate stretchability. The cushion layer 20 is formed of a urethane foam, and is arranged for the purpose of improving the feel when the steering wheel cover is gripped. The surface layer 30 is mainly for securing the design of the steering wheel cover. By applying various designs to the surface layer, a steering wheel cover having a design in line with the user's taste can be produced.

  The vertical section of the automobile steering wheel cover 100 according to the first embodiment is formed by combining circular arcs having different radii to form an annular vertical section. The side having the arc with a short radius is the back side, and the longer radius is the front side. Thereby, it can be set as the opening edge side 10 from which circumferential length differs. That is, the opening end sides 11 and 12 forming the opening 15 of the steering wheel cover are provided with different circumferential lengths on the back side 11 and the front side 12, and the opening side edge 11 on the back side is on the front side. The circumference is formed longer than the opening end side 12. That is, the distance from the ring-shaped center is different, and the distance B from the center to the opening end side 11 on the back side is formed longer than the distance C from the center to the opening end side 12 on the near side. Therefore, when the automobile steering wheel cover is viewed from the front side, the opening end side 11 on the back side cannot be visually recognized.

  The vertical section of the automobile steering wheel cover 100 has an annular shape having an opening 15 in a part thereof. As described above, since the length of the opening edge is different, the opening 15 is shifted from the lateral direction (that is, the center direction of the ring) in FIG. In the cross section of the steering wheel cover 100 according to the first embodiment, the thickness of the base portion is 2.7 mm, and the radius a of the arc of the outer surface of the base member 10 in the region α is as shown in FIG. It is formed with an arc of 17.75 mm, an arc radius b of the outer surface of the base member 10 in the region of γ is formed with an arc of 17 mm, and the β portion in the middle is formed with a straight line. Further, the region δ has an arc having an arc radius c of 9 mm on the outer surface of the base member 10. Of course, the specific radius described above is merely an example, and it is needless to say that it can be appropriately selected according to the automobile steering wheel to be used. Further, there is no problem whether or not the straight line portion between them is provided, and the straight line portion may be provided or the length thereof may be adjusted according to the thickness or shape of the steering wheel.

  The steering wheel cover for automobiles manufactured as described above is attached by opening the opening end 11 and separating the opening 10 so as to be fitted into the steering wheel. At this time, since the opening end side 11 on the back side has a long circumference, it can be easily attached without widening.

  By adopting the configuration according to the first embodiment, the portion γ having a short outer surface radius is tightly wound and pressed on the steering wheel, so that it can be easily fitted and difficult to come off.

  Further, in the first embodiment, since the region δ has a shape facing further inward, the region δ is attached in a state of being urged to the steering wheel so that a gap is generated between the steering wheel and the open end 11. Can be prevented, and can be made difficult to come off.
