Abstract: An airbag device includes an airbag that is supplied with gas generated by an inflator during a vehicle collision and that inflates and deploys from a rear side of a vehicle seat toward a front side via an upper side. In an inflated and deployed state, the airbag includes a pair of front-rear chambers extending in a seat front-rear direction via left and right sides of a head of a passenger, an airbag body that is in communication with the pair of front-rear chambers and that is disposed at a front side of the passenger between the pair of front-rear chambers, and a pair of rear tethers including one-end portions attached to the airbag body and other-end portions attached to a seatback of the vehicle seat. At least a rear tether on a side door side is configured so as to be releasable after a collision of the vehicle.

Abstract: An airbag device has an airbag. The airbag has a front-rear chamber and an airbag main body. The front-rear chamber has a left and right pair of front-rear extending portions that pass by respective left and right sides of a head of a passenger and inflate and deploy toward the seat front side, and a connecting portion connecting front end portions of the pair of front-rear extending portions in a seat left-right direction. Gas is supplied to the airbag main body via a communication hole positioned at a seat rear side of the connecting portion of the front-rear chamber that has inflated and deployed. Owing to inflation and deployment of the front-rear chamber, the airbag main body passes through a gap between a ceiling of the vehicle and the head from the seat rear side toward the seat front side, and thereafter, inflates and deploys toward the seat rear side.

Abstract: An airbag device has an airbag. The airbag has a front-rear chamber and an airbag main body. The front-rear chamber has a left and right pair of front-rear extending portions that pass by respective left and right sides of a head of a passenger and inflate and deploy toward the seat front side, and a connecting portion connecting front end portions of the pair of front-rear extending portions in a seat left-right direction. The airbag main body inflates and deploys toward a side of the passenger at a seat rear side of the connecting portion, later than the front-rear chamber. The airbag main body has a downward-force applying portion that applies force directed toward a seat lower side to the airbag at a time when the passenger is restrained by the airbag.

Abstract: An airbag device has an airbag. The airbag has a front-rear chamber and an airbag main body. The front-rear chamber has a left and right pair of front-rear extending portions that pass by respective left and right sides of a head of a passenger seated in a vehicle seat and inflate and deploy toward the seat front side, and a connecting portion connecting front end portions of the pair of front-rear extending portions in a seat left-right direction.

Abstract: A distance measurement device includes an imaging optical system, an imaging device, and a distance measurement section which measures based on a plurality of images captured by the imaging device, a distance from the imaging device to the target to be imaged. The imaging optical system includes a polarization beam splitting section which splits a first polarization beam having a first polarization direction and a second polarization beam having a second polarization direction substantially orthogonal to the first polarization direction and allows the polarization beam splitting section to be incident on the imaging device. The imaging device receives the first polarization beam to capture a first polarization image and the second polarization beam to capture a second polarization image. The distance measurement section measures the distance to the target to be imaged on the basis of the first polarization image and the second polarization image.

Abstract: A first mirror has a first reflecting surface convexed in a first direction, a first apex, and a first fan shape. A second mirror has a second reflecting surface convexed in a second direction, a second apex, and a second fan shape. An imaging optical system forms images from a first light emitted from an object, reflected by the first reflecting surface, and subsequently further reflected by the second reflecting surface, and a second light emitted from the object and reflected by the second reflecting surface. The first and second fan shapes have interior angles of 180° or more. A center position of the image sensor is displaced with respect to an optical axis of the imaging optical system. A short side of a photo-receiving surface of the image sensor and a center line of the image of the first or second fan shape are approximately parallel.

Abstract: The image display apparatus generates a driving control signal for generating image light on the basis of an image signal, and allows an image projector to generate the image light to form a pixel on a screen in accordance with a modulation timing by performing modulation driving for a light source, and to generate the image light so as to scan the screen while a light emission direction of the image light changes by performing scan driving, allows a gaze-direction detector to detect a gaze direction of a user, and allows a projection-direction driver to change a projection direction of the image light in accordance with the gaze direction. In the first mode, the image display apparatus controls modulation driving and scan driving so that a configuration of a pixel region on the screen changes from a relatively high pixel density region to a relatively low pixel density region.
