Provided is a spectacle lens including a lens substrate, a multilayer film located on an object-side surface of the lens substrate, and a multilayer film located on an eyeball-side surface of the lens substrate, wherein a blue light absorption rate is 10.0% or higher, the lens substrate includes a blue-light-absorbing compound, and an average reflectance in a wavelength range of 400 nm to 500 nm measured on each of the object-side surface and the eyeball-side surface of the spectacle lens is in a range of 10.0% to 20.0%, and a luminous reflectance measured on each of the object-side surface and the eyeball-side surface of the spectacle lens is less than 2.0%.

Spectacle lens and spectacles

An aspect of the present invention relates to a spectacle lens including a multilayer film of a vapor deposition film (excluding a metal film and a metal alloy film) directly or indirectly at least on one surface of a lens substrate. The multilayer film includes at least one high refractive index layer and at least one low refractive index layer, the total optical film thickness of the high refractive index layer is &#x3bb;/4 or more at a wavelength &#x3bb;=780 nm, and a reflection spectrum measured in a wavelength range of 380 to 2000 nm on a surface having the multilayer film has a maximum reflectance in a wavelength range of 800 to 1350 nm.

Spectacle lens

In one form, a passenger airbag device is provided including an airbag; a retainer having an opening on a passenger side; a bag ring provided to an inside of the retainer; and the gas generating device; wherein: the retainer further includes a base wall that forms a substantially rectangular outer edge shape; two first peripheral wall portions; and two second peripheral wall portions; and the bag ring comprises: a bottom wall portion configured to hold a peripheral edge portion of the opening of the airbag; a first upright wall having a predetermined first height dimension, that is arranged so as to face the first peripheral wall portion of the retainer; and a second upright wall having a predetermined second height dimension larger than the first height dimension, that is arranged so as to face the second peripheral wall portion of the retainer.

Passenger airbag device

There is provided an airbag folding method for folding an airbag. The method includes in the following order: (a) folding the inner panel and the outer panel into a symmetrical substantially rectangular shape such that a groove of the concave region is located along a center line, wherein the center line passes through a center of the introduction port and symmetrically divides the inner and outer panels; (b) folding the inner and outer panels along fold lines from right and left edges thereof toward the center line, wherein the fold lines are substantially parallel to the center line; and (c) folding and rolling up the inner and outer panels from both ends of the center line toward the introduction port.

Airbag folding method and airbag apparatus

An airbag apparatus to be mounted on a vehicle such as a motor vehicle includes an airbag and a gas supply device. The airbag is inflated to a rear side of a vehicle from a front side thereof in front of a vehicle passenger for protecting the passenger in case of a vehicle accident. The airbag includes a right airbag section extending vertically on a right side of the vehicle and a left airbag section extending vertically on a left side of the vehicle in the inflated state. The right or left airbag section located closer to a side portion of the vehicle has an upper edge lower than that of the left or right airbag section, so that the right or left airbag section does not interfere with the side portion.

Airbag apparatus and method of manufacturing airbag

The positioning of an airbag plate with respect to an inflator is achieved so as to prevent the generation of a rattle that may otherwise be caused by vibrations during vehicle travel. The bottom side of a column-shaped inflator that injects pressurized fluid is supported by a retainer. An opening edge of an airbag body is clamped between an airbag plate and the retainer when the airbag plate, which is located on the upper side of the inflator, is engaged with the retainer. The edge of the bottom opening of the airbag body is clamped between the airbag plate and the inflator. In one embodiment, shoulders, which are provided on the airbag plate, abut both ends of the inflator. In another embodiment, tongue strips, which are provided on the airbag plate, abut both ends of the inflator.

Airbag apparatus

A case of an airbag unit includes a case body for forming a storage room for accommodating an airbag, and a movable component attached to the case body for forming at least a part of an edge of an opening of the case body. The movable component has a lower end portion bent in a direction away from the case body. The movable component is movable toward the bottom when an external force is applied to the case.

Airbag unit and case of airbag unit

A case of an airbag unit has a case body for forming a storage room for accommodating an airbag. The case body has a bottom section, a pair of first side walls, and a pair of second side walls. The case also has a movable component disposed adjacent to an outer surface of one of the first side walls, and retractable toward a base end along the case body in response to an external force applied to the case. One of the first side walls has a plurality of pillars extending upwardly from the bottom to form cut-off portions therebetween extending downwardly from the upper opening.
