  • Patent number: 11813088
    Abstract: A grip includes a core that forms a structure of the grip and has electrical conductivity, a sensing electrode for detecting a biological signal of a user, and a ground electrode that is connected with a reference voltage portion. The core, the sensing electrode and the ground electrode are insulated from one another. The core is disposed inside the grip, and the sensing electrode is exposed on a surface of the grip. The sensing electrode and the core are connected with one another via a voltage follower circuit. The ground electrode is located at such a position that the core is able to reduce a parasitic capacitance which would be formed between the ground electrode and the sensing electrode.

  • Patent number: 11077818
    Abstract: An airbag device includes an airbag, an airbag cover which covers the airbag, and a holder which holds the airbag and the airbag cover. The airbag cover includes a door portion which is pushed by the inflating airbag and opened with a hinge portion around a rotation center. A functional component is provided on the door portion and connected to and held by a deformable holding member. The holding member includes a distal side connecting portion connected to the functional component, a proximal side connecting portion connected to a part which can ensure an attachment strength, and a deformation portion which is provided between the distal and proximal side connecting portions and deformed to maintain a connection and holding state of the distal side connecting portion with the functional component and reduce a centrifugal force of the functional component acting on the hinge portion when the airbag is inflated.

  • Patent number: 7891698
    Abstract: A plate is provided on an air bag module, and a first pin on which a recessed portion is formed and a second pin on which a recessed portion is formed are provided in positions which are spaced apart from each other. A first clip adapted to be brought into engagement with the recessed portion and a second clip adapted to be brought into engagement with the recessed portion are provided on a steering wheel main body. In addition, bushes for biasing the plate in a direction in which the plate is separated from the steering wheel main body are provided between a first snap-fit portion which is made up of the first pin and the first clip and a second snap-fit portion which is made up of the second pin and the second clip.
