An armrest includes an arm-side wire harness and an arm body member. The arm-side wire harness includes an electric wire and an arm-side connector on an end of the electric wire to be coupled to a mount member-side connector mounted on a mount member. The arm body member includes an arrangement section in which the electric wire of the arm-side wire harness is arranged and a mount member-side wall that is to be arranged opposite the mount member. The arm body member is to be fixed to the mount member while the mount member-side wall being opposite the mount member. The mount member-side wall includes a connector insertion hole through which the mount member-side connector can be inserted. The arm-side connector and the mount member-side connector can be arranged in the arrangement section. The arm body member includes an operation hole that is continuous from the arrangement section.

Armrest and seat with armrest

An armrest includes a frame, a mounting portion included in the frame and having a mounting surface with which the mounting portion is mounted on a bracket of a seat, an armrest-side wire harness arranged in the frame, and an armrest-side connector connected to the armrest-side wire harness and being open in a direction from the mounting surface toward the bracket.

Armrest

An armrest described herein includes an arm-side wire harness including an electric wire and an arm-side connector that is on an end of the electric wire and is to be coupled to a seat-side connector mounted on a seat. The armrest further includes an arm body member including an electric wire routing cavity in which the electric wire of the arm-side wire harness is arranged and a seat-side wall that is to be arranged opposite a seat frame of the seat. The arm body member is to be fixed to the seat frame while the seat-side wall being opposite the seat frame. The seat-side wall includes a connector insertion hole through which the arm-side connector can be inserted. The arm body member includes an operation hole that is continuous from the connector insertion hole via an arrangement section of the electric wire routing cavity.

An armrest includes a bracket fixed to a frame of a seat, an armrest body member rotatably mounted on the bracket, a receiver coil mounted in the armrest body member, and a transmitter coil mounted in the bracket and transferring power to the receiver coil with a non-contact transmission system.

An armrest includes a first branch cable and a second branch cable, a frame, a skin covering the frame, and a foamed resin material. The frame includes a first routing section and a second routing section in which the first branch cable and the second branch cable are arranged, respectively. The foamed resin material is disposed on an inner side of the skin. The first branch cable and the second branch cable are disposed within the foamed resin material in the first routing section and the second routing section.

An armrest according to the technology described herein includes a bracket, an armrest body, a device connecting port, an armrest-side connector, and a cable. The bracket is fixed to a seat frame. The armrest body is attached to the bracket to be rotatable. The device connecting port is exposed through an outer surface of the armrest body. The armrest-side connector is fixed to the seat frame at a position different from the bracket. The cable includes an end connected to the device connecting port and an end connected to an armrest-side connector. The armrest body includes a cable retaining portion through which the cable is passed and in which the cable is retained. Any one of the bracket and the armrest body includes a hole (an elongated hole) that allows movement of the cable along with rotation of the armrest body.

An armrest includes a cable to be connected to a seat-side cable arranged on a seat, and a body member that is mountable on the seat and includes a routing section therein in which the cable is arranged. The cable includes an arranged portion that is arranged in the routing section and a connecting operation section that extends outside the routing section when being connected to the seat-side cable. The connecting operation section is arranged in the routing section when the body member is mounted on the seat.

Provided is an active noise cancellation apparatus capable of reliably reducing road noise by a technique other than mounting a vibration generator on a floor panel itself or another plate-like interior part itself, while reducing costs and size of the apparatus. A reference signal detector is mounted on a knuckle and the vibration generator is mounted on a wheel housing or a suspension member. An error signal detector detects vibration of the wheel housing or vibration of the suspension member as an error signal, or detects sound in a vehicle interior as an error signal. A controller controls the vibration generator based on the reference signal and the error signal so as to reduce the error signal.

Active noise cancellation apparatus

An active vibration insulator includes an electromagnetic actuator, a controller, and a bad-roads processor. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The controller carries out vibrating-forces generation control. In the vibrating-forces generation control, the electric-current supplies are made variable so as to actively inhibit vibrations generated by an on-vehicle vibration generating source of a vehicle from transmitting to a specific part of the vehicle based on cyclic pulsating signals output from the on-vehicle vibration generating source. Thus, the controller lets the electromagnetic actuator generate the vibrating forces. The bad-roads processor stops the vibrating-forces generation control effected by the controller when the vehicle travels on bad roads.

Active vibration insulator

An active vibration insulator includes an electromagnetic actuator, a control-signals generating device, a driver, a calculator, and a judging device. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The control-signals generating device generates cyclic control signals based on cyclic pulsating signals output from a vibration generating source of a vehicle. The cyclic control signals actively inhibit vibrations generated by the vibration generating source from transmitting to a specific part of the vehicle. The driver drives the electromagnetic actuator by making the electric-current supplies variable based on the cyclic control signals. The calculator calculates an estimated transfer function composed of estimated values of a transfer function for a transfer system including the electromagnetic actuator and the driver. The judging device judges an inoperative malfunction of the electromagnetic actuator based the estimated transfer function.

Disclosed is a dynamic damping device for a steering system of an automotive vehicle, which equipped with a telescopic steering column, including a plurality of mutually independent dynamic dampers, each including a mass member and a spring member for elastically supporting the mass member to the steering column or wheel. At least two of natural frequencies of the plurality of dynamic dampers are tuned to a higher and a lower frequency range in relation to a central value of a range of variation in a natural frequency of the steering wheel due to an expansion or contraction of the telescopic steering column, within the range of vibration in the natural frequency of the steering wheel. Further, a difference between adjacent ones of the natural frequencies of the plurality of dynamic dampers is made held within 10-40% of the central value of the range of vibration in the natural frequency of the steering wheel.
