A decorative member for a steering wheel which is used for being attached to a resin member formed around a ring core metal of a steering wheel. The decorative member includes a base layer attached to the resin member, a design part arranged on the base layer, and a heater arranged between the design part and the base layer. The base layer may include an extraction part at an intermediate position in a longitudinal direction thereof such that a lead wire connected with the heater is led out of the extraction part.

A handle in which a sensor layer capable of detecting grip is disposed on a gripping portion that is gripped at a time of steering. The gripping portion includes a core material, a covering layer formed of urethane foam, which is disposed by die-molding so as to cover a periphery of the core material, the sensor layer, and a protective layer covering the sensor layer. The sensor layer is formed of a mold coat agent formed of a urethane-based paint containing a conductive material. The mold coat agent is applied to a die surface of a molding die of the covering layer. At a time of molding the covering layer, the sensor layer formed of the mold coat agent is disposed on a surface side of the covering layer.

The present invention relates to a synthetic leather for a steering wheel cover of a vehicle, and a method for preparing the same. The synthetic leather including a fiber base layer (101) including a microfiber nonwoven fabric, an urethane porous layer (102) formed on the fiber base layer, a polyurethane resin skin layer (104) formed on the urethane porous layer, and prepared by polymerizing an isocyanate compound and a polyol compound including polycarbonate-based polyol, fluorine-based polyol and ester-based polyol, and an adhesive layer (103) for adhering the urethane porous layer and the skin layer.

In order for a core metal member having three spoke parts to be usable in a three-spoke steering wheel and a two-spoke steering wheel having one fewer spoke part than the three-spoke steering wheel, one of the spoke parts of the core metal member is a separable spoke part, which is separable along separation marks provided on vertical spokes forming the separable spoke part. Each vertical spoke constituting the separable spoke part is provided with an indented first fragile portion and an indented second fragile portion which also act as the separation marks.

A steering wheel includes a core and a foamed polyurethane coating that covers a ring section of the core. The foamed polyurethane coating is formed by foam molding of a polyurethane material containing 91 parts by mass of a base polyol, 10 to 25 parts by mass of a pigment, 1 to 3 parts by mass of a benzotriazole ultraviolet absorber, 0.8 to 2.5 parts by mass of a hindered amine photostabilizer, and a polyisocyanate. A total amount of the ultraviolet absorber and the photostabilizer is 2.7 parts by mass or more. The foamed polyurethane coating is in the form of an integral skin foam including a highly foamed core foam and a lowly foamed skin layer. The surface of the skin layer is not provided with a coating film formed from a coating material, and serves as a product surface that assumes a color of the pigment.

A decoration article having a clear layer includes a rod-shaped core material, a cylindrical decorative cover having a shape retaining property, configured to cover the core material over an entire circumference in a sectional circumferential direction of the core material, including a plurality of split members split along the sectional circumferential direction of the core material and having a base part and a decoration layer provided on a surface of the base part, and a transparent clear layer formed by a mold forming so as to cover an outer surface of the decoration layer over an entire circumference in a sectional circumferential direction of the decoration cover covering the core material.

A steering wheel is provided with a heater element on the rim. The heater element is mounted at least on a part of a core of the rim, and a cladding layer formed from synthetic resin foam covers an outer circumference of the heater element. The heater element includes a cord-shaped heater and a base material. The base material includes an insulation sheet that is formed from synthetic resin foam and disposed to face towards the core and a permeable sheet that is formed from non-metal which allows permeation of the cladding layer. The insulation sheet and permeable sheet are bonded together and sandwich and support the cord-shaped heater there between.

Various implementations include an improved steering wheel and methods of making the same. The improved steering wheel includes a carbon fiber mat that is preimpregnated with an epoxy resin that is wrapped adjacent at least a portion of a steering wheel frame. The edges of the mat that overlap are coupled together directly via the epoxy resin by heat curing the mat. The preimpregnated mat does not crack when subjected to thermal cycle tests, which is an improvement over prior art steering wheels that include raw carbon fiber mats that are coupled to the frame using a separate adhesive.

The invention relates to a method for manufacturing a steering wheel comprising a frame, a covering formed by a body, overmoulded onto the frame, and at least one insert, the method comprising steps aimed at: providing at least one recess in the covering, and producing the insert so that an assembly of the insert with the body of the covering allows the recess, to be at least partially covered, wherein the insert is obtained in a single piece with the body of the covering.

A method for manufacturing a vehicle steering wheel, the steering wheel comprising: —a rim, —an outer sheath formed by at least one strip attached around at least one part of the rim, —at least one device passing through the outer sheath, the method comprising at least the following steps: —positioning the strip around the rim, —attaching the strip to the rim in order to form the outer sheath, —forming an opening in the outer sheath facing an internal part of the device, —folding portions of the outer sheath towards the inside of the rim.
