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 laser radar device includes: a light source for outputting laser light; a scanner for causing the laser light to scan; a first optical system for receiving the laser light caused to scan by the scanner and incident on the first optical system and emitting the incident laser light in such a manner that a horizontal component of the incident laser light is different from a horizontal component of the laser light to be emitted; and a second optical system for receiving the laser light caused to scan by the scanner and incident on the second optical system and emitting the incident laser light in such a manner that an incident area of the incident laser light in the horizontal direction is the same as an incident area of the first optical system in the horizontal direction, and an emission area of the incident laser light is different from an emission area of the first optical system.

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: A vehicle bumper structure to be applied to a vehicle includes an impact absorber to be disposed on a front end side or a rear end side of the vehicle so as to extends in a vehicle width direction. The impact absorber includes small reaction section and a large reaction section. The small reaction section is to be disposed on an outer end side in the vehicle width direction. The small reaction section is configured to generate a predetermined reaction against a colliding object. The large reaction section is to be disposed on an inner side of the small reaction section in the vehicle width direction. The large reaction section is adjacent to the small reaction section. The large reaction section is configured to generate a larger reaction against the colliding object than the predetermined reaction.

Abstract: A collision detection device includes an impact absorber and a collision detector. The impact absorber extends along a vehicle width direction between a bumper face and a bumper beam of a vehicle, and is configured to absorb impact by being deformed upon collision of the vehicle. The collision detector extends along the vehicle width direction, includes a lower collision detector and an upper collision detector, and is configured to detect that the collision has occurred by being deformed upon the collision of the vehicle. The upper collision detector has greater flexibility than the lower collision detector.
