Method for bonding a sheetlike cover material to a shaped article, using an adhesive film comprising at least one layer of a heat-activatedly bondable adhesive, where the adhesive film is disposed, over the full area or a partial area, between the cover material and the shaped article, the heat-activatedly bondable adhesive as yet not adhering to the shaped article, wherein the cover material is pulled onto the shaped article under tension, so that the layer of the heat-activatedly bondable adhesive contacts the shaped article, and the activation of the heat-activatedly bondable adhesive is brought about by means of the pressure resulting exclusively from the tension, and optionally of heat introduced by means of external energy supply, whereby the heat-activatedly bondable adhesive adheres to the shaped article and a durable connection of the cover material to the shaped article is produced.

A steering wheel damper for a vehicle, and a manufacturing method thereof, the method includes putting a plate which is directly fixed to a steering wheel and has a plurality of through holes and a mass member having a predetermined weight to reduce vibration and a central pin in a mold in order, injection-molding rubber, and molding a connection member for connecting the plate and the mass member and a cushion member for limiting movement of the mass member. Therefore, the steering wheel damper and the manufacturing method thereof can simplify the manufacturing process, improve productivity, and enhance durability and marketability since the plate, the mass member and the connection member are firmly coupled and movement of the mass member is limited so that the mass member does not collide with surrounding components while the vehicle is shaken.

It is provided a device for bonding at least one material segment to a steering device. The device comprises at least two form fitting segments, wherein at least one of the form fitting segments is movably mounted relative to the at least one other form fitting segment, wherein the form fitting segments are configured in such a way that they can at least sectionally enclose the steering device, in particular the steering wheel rim of the steering device; a receptacle for receiving the steering device; a drive mechanism for moving the at least one movably mounted form fitting segment towards the steering device.

The invention relates to a steering wheel (1), especially a leather steering wheel, comprising a steering wheel skeleton (10), a foam padding (11) surrounding the steering wheel skeleton (10) at least partially and a wrapping (12) which encompasses the foam padding (11) at least in portions, wherein adjacent longitudinal edges (13) of the wrapping (12) are covered by a profile bead (20), in particular a decorative bead (24), the profile bead (20) including at least one anchoring element (21) which is fixed directly in the foam padding (11) for fastening the wrapping (12). Moreover the invention relates to a method of manufacturing such steering wheel.

A steering wheel (1) includes a steering wheel skeleton (10), a foam padding (11) surrounding the steering wheel skeleton (10) at least partially, and a wrapping (12) which encompasses the foam padding (11) at least in portions. Adjacent longitudinal edges (13) of the wrapping (12) are covered by a profile bead (20), in particular a decorative bead (24). The profile bead (20) includes at least one anchoring element (21) which is fixed directly in the foam padding (11) for fastening the wrapping (12).

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.

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 steering wheel providing minimal cost increase due to addition of a temperature adjustment function. The steering wheel, includes: a boss portion to be connected to a steering column; a grip portion to be gripped by a driver; and a spoke portion, which connects the boss portion and the grip portion to each other. The grip portion includes: a synthetic resin layer molded by a synthetic resin; a cored bar; a flexible porous material layer disposed on an outer peripheral surface side of the cored bar; and a heater element disposed on an outer surface of the porous material layer. The porous material layer and the heater element are covered by the synthetic resin layer.

A method for producing a covered steering wheel for a vehicle. A steering wheel skeleton is overmolded with a matrix material. A covering material is coated on its non-visible side with an activatable material. The coated covering material is applied to the overmolded steering wheel skeleton so that its non-visible side faces the overmolded steering wheel skeleton. Longitudinal edges of the covering material are joined together. The activatable material is activated with creation of an integral connection between the covering material and the matrix material.
