  • Patent number: 11180108
    Abstract: A preparatory folded form is a form of an airbag in an initial stage in a folding process which has not yet been reduced in size for storage in a steering wheel. The airbag includes a driver-side wall, and a vehicle-side wall which includes an inlet port in a vicinity of the center, and a plurality of taken-in portions towards the outer edge for reducing a length of the outer edge of the vehicle-side wall. The preparatory folded form includes an upper-surface portion composed of a central portion of the driver-side wall, a lower-surface portion composed of a peripheral portion of the inlet port in the vehicle-side wall, and at least one invaginated portion that is composed of a portion of the airbag located between the upper- and lower-surface portions including the taken-in portions, and is invaginated in between the upper- and lower-surface portions towards the inlet port. The upper-surface portion, invaginated portion and lower-surface portion lie over one another.

  • Publication number: 20210300454
    Abstract: A steering wheel includes an annular rim portion, a boss section, one or more spokes interconnecting the rim portion and boss section, and a core member interconnecting these portions, the core member including a wheel portion disposed in the rim portion. The steering wheel further includes a cladding layer disposed around the wheel portion, a skin layer disposed on a front surface of the rim portion, and a sensor layer disposed between the cladding layer and the skin layer for detecting the driver's grip. The sensor layer includes a sheet-shaped substrate having stretch properties, a sensor composed of a conductive ink having stretch properties and applied to a front surface of the substrate, and an insulation sheet covering the sensor and having stretch properties. The sensor layer is generally formed into an annular band and mounted on an outer circumferential portion of the cladding layer by being stretched and expanded.

  • Patent number: 11097683
    Abstract: An airbag includes a mounting portion, a top wall deployable towards a vehicle occupant, and a circumferential wall disposed between the mounting portion and top wall. An airbag base member for forming the airbag includes a top-forming panel for forming the top wall, and at least three circumferential panels that extend generally radially from the top-forming panel and form the circumferential wall by being joined together by adjoining edges thereof. Each of the circumferential panels is formed into a generally band-like contour which has a first and a second curving edges that make the circumferential panel enlarge in width from the leading end towards an intermediate portion and then narrow towards the top-forming panel. When the airbag base member is laid flat, adjoining edges of any two adjoining circumferential panels are generally symmetrical to each other in curving shape with respect to a line disposed there between.

  • Publication number: 20210094498
    Abstract: An airbag device includes a steering wheel a rim portion of which has a longer length in a left and right direction than in a front and back direction, and an airbag mounted on a boss section of the steering wheel. An outer shell of the airbag includes a vehicle-side wall that is configured to be supported by an upper surface of the rim portion when deployed, and a driver-side wall a central region of which is configured to deploy generally vertically for receiving the driver. The airbag as deployed includes, in a rear portion of the vehicle-side wall, a locking inflatable portion that protrudes downward from a vicinity of the upper surface of the rim portion of the steering wheel to be locked by a rear surface of the rim portion and prevent a front portion of the airbag from slipping forward.

  • Patent number: 10919483
    Abstract: An airbag for steering wheel is configured to inflate so as to cover an upper surface side of a ring part of a steering wheel. Outer peripheral edges of a vehicle body-side wall part and a driver-side wall part are joined such that the airbag is formed to have a bag shape, and an inlet opening is arranged at a vicinity of a center of the vehicle body-side wall part. The vehicle body-side wall part is formed with a concave part to be concave upward toward the driver-side wall part upon completion of the inflation so that a rear part-side region of the ring part can be entered into the concave part, and the concave part is arranged at the vehicle body-side wall part so that the ring part is entered into the concave part when a driver is received by the airbag upon completion of the inflation.
