Abstract: An occupant protecting device provided inside or below a seat cushion of a vehicle seat, containing: an airbag cushion capable of expanding and deploying to push up a seat surface of the seat cushion; and an inflator that supplies gas for expansion and deployment into the airbag cushion in the event of a vehicle emergency. The airbag cushion has front attaching points and rear attaching points attached to the vehicle seat side, and an expanding and deploying part that is expanded and deployed by the gas from the inflator. At least a portion of the expanding and deploying part overlaps itself in an up-down direction by folding between front attaching points and rear attaching points in a condition prior to expanding and deploying.

Abstract: A driver seat airbag device includes an airbag cushion installed at a center portion 108 of a steering wheel of a vehicle which is configured to expand and deploy toward an occupant in a driver seat; and an inflator that supplies gas to the airbag cushion. The airbag cushion includes a steering side panel provided on the steering wheel side and an occupant side panel joined to the occupant side of the steering side panel. The shape of the expanded and deployed airbag cushion is such that the portion, which is the largest area of the cross section orthogonal to the axis of rotation of the steering wheel, is formed further toward the front side of the vehicle than the center portion between the frontmost portion of the steering side panel and the rearmost portion of the occupant side panel.

Abstract: To provide a motorcycle airbag device that contributes to the stabilization of the deployment behavior and the deployment posture of the airbag.
An airbag device mounted on a motorcycle having a gas generator that generates an expansion gas, where the airbag is expanded by the expansion gas, and by deploying in front of the occupant, restrains forward movement of the occupant. Furthermore, the airbag has a stepped portion that protrudes forward when deployed and is supported by a structural portion around the top of the handlebars of the motorcycle.

Abstract: An occupant protecting device provided inside or below a seat cushion of a vehicle seat, comprising an airbag cushion capable of expanding and deploying a seat surface of the seat cushion; and an inflator. The airbag cushion includes a lower panel, an upper panel longer than the lower panel in the front-rear direction of the vehicle seat, and mutually opposing side panels joined to the lower panel and the upper panel. The airbag cushion has a first mounting point attached to the vehicle seat side and a second mounting point attached to the vehicle seat side on the rear side of the first mounting point in the front-rear direction of the vehicle seat. The lower panel and the upper panel are mutually joined to a first mounting point and a second mounting point.

Abstract: An occupant protection device capable of suppressing the occurrence of submarining and ensuring initial waist restraint performance. An occupant protection device provided inside or below a seat cushion of a vehicle seat, provided with:



an airbag cushion capable of expanding and deploying to push up a seat surface of the seat cushion; and
an inflator that supplies gas for expansion and deployment into the interior space of the airbag cushion during a vehicle emergency. The airbag cushion includes an expansion and deployment part that expands and deploys by gas from the inflator, and an exhaust vent part protruding from the peripheral edge of the airbag cushion. The expanded and deployed airbag cushion is configured such that the exhaust vent opens and allows the internal space of the expansion and deployment part to communicate with the outside when a load acts on the expansion and deployment part.

Abstract: A cushion of an airbag device includes an inner inflating section convexly inflating toward the rear of a vehicle and restraining the head of an occupant from the front of the vehicle, protrusions provided to the sides of the inner inflating section in a vehicle width direction and capable of inflating so as to protrude further toward the rear of the vehicle than the inner inflating section, and outer inflating sections provided between the inner inflating section and the protrusions and temporarily convexly inflating toward the rear of the vehicle within a smaller range than the expansion range of the inner inflating section and the protrusions. The outer inflating sections are squashed by the inner inflating section and the protrusions and, as a result, the protrusions are in a posture of being pulled toward a side of the inner inflating section.

Abstract: A knee airbag device according to the present invention includes: an airbag that restrains a lower extremity of an occupant by expanding and deploying below an instrument panel of a vehicle; and an inflator that supplies expansion gas to the airbag. The airbag includes, when the inside of the vehicle is a first side and the outside of the vehicle is a second side, a first portion positioned on the first side and a second portion positioned on the second side. Furthermore, the first portion of the airbag protrudes more toward the occupant side than the second portion.

Abstract: A curtain airbag attached to a vehicle body and expanded and deployed by a gas from an inflator containing: a first region along a lower edge; a second region adjacent above the first region with a first fold line; a third region adjacent above the second region with a second fold line formed on an opposite side of the first fold line across the second region. The first region is in a condition folded back at the first fold line to face a first surface side of the second region, the second region is in a condition folded back at the second fold line such that the folded back first region is between the second region and the third region, the third region is in a condition rolled upward on a second surface side. Rolling starts from the second fold line.
