Abstract: The airbag device includes an airbag and a gas generator. The gas generator includes a body containing inflation gas and sealed with an unsealable lid, and a discharge portion that includes a housing, an outlet that is formed in the housing and allows outflow of gas to the airbag when the body is unsealed, a piercing pin for unsealing the lid, a spring for moving the pin, a retaining member that retains the spring, and a sliding mechanism that shifts the retaining member to a release position. The sliding mechanism includes a drive source and a connecting member that shifts the retaining member to the release position by a driving force of the drive source. The piercing pin, spring, lid and a portion of the retaining member retaining the spring are housed in the housing. The drive source and connecting member are partitioned from a gas channel inside the housing.

Abstract: A wearable airbag device for protecting the hip of a wearer includes an airbag adapted to be worn around the pelvis and inflatable with an inflation gas. The airbag includes: an inner wall configured to face the wearer at airbag deployment; an outer wall opposite the inner wall and having a circumferential edge jointed with that of the inner wall so that the airbag has a substantially board shape when inflated; a contact portion disposed in an upper reach of a stream of inflation gas and configured to be deployed at a side of the pelvis; a protecting portion configured to be deployed in such a manner as to extend downward from the contact portion for covering an outer side of the trochanter of femur at airbag deployment; and a float-preventing means for preventing the protecting portion from floating away from the body of the wearer at airbag deployment.

Abstract: A wearable airbag device includes a wearable member and an airbag held by the wearable member and inflatable with an inflation gas fed from a gas generator. The airbag includes a bag body that forms an outer shell of the airbag which includes an inner wall adapted to face the wearer when worn and an outer wall opposite to the inner wall, the bag body including one or more protecting inflatable portions for covering and protecting one or more targeted body parts respectively, and an inner bag that is disposed inside the bag body and configured to be inflated with the inflation gas from the gas generator. The inner bag includes one or more supply ports for forwarding the inflation gas to the bag body. Each of the supply ports is configured to emit the inflation gas toward one of the protecting inflatable portions and toward the outer wall.

Abstract: A wearable airbag device adapted to be worn by a wearer is disclosed, including a gas generator that is configured to be actuated at fall of the wearer, an airbag that includes a plurality of inflatable portions that are partitioned from one another, the plurality of inflatable portions each including an gas inlet port and being configured to be inflated with an inflation gas fed from the gas generator via the gas inlet port for protecting a targeted body part of the wearer, and a gas switching mechanism that is disposed in a pathway of the inflation gas from the gas generator toward the plurality of inflatable portions, the gas switching mechanism being configured to switch a destination of the inflation gas emitted from the gas generator over to only one inflatable portion disposed in a falling direction of the wearer out of the plurality of inflatable portions.

Abstract: An image rotation adapter that is configured to be detachably mounted between an image capturing lens and a camera main body in a camera and includes a first prism configured to invert the object image passed through the image capturing lens by reflecting an odd number of times object light passed through the image capturing lens and a second prism that is supported rotatably about the optical axis, and that is configured to further invert the object image inverted by the first prism by reflecting an odd number of times the object light passed through the first prism; an operation device configured to perform an operation to rotate the second prism; and a relay optical system configured to re-form the object image passed through the second prism on the light receiving surface of the image pickup device.

Abstract: An image rotation adapter that is configured to be detachably mounted between an image capturing lens and a camera main body in a camera in which the image capturing lens is detachably provided to the camera main body and in which an object image passed through the image capturing lens is formed on a light receiving surface of an image pickup device via a prism incorporated in the camera main body, and that is configured to rotate the object image formed on the light receiving surface of the image pickup device, the image rotation adapter comprising: a first prism that is formed to have an optical path length close to the optical path length of the prism incorporated in the camera main body, that is arranged in an optical path before the object image passed through the image capturing lens is formed at a predetermined position in the image rotation adapter, and that is configured to invert the object image passed through the image capturing lens by reflecting an odd number of times object light passed thro
