An airbag assembly according to the present disclosure includes an airbag cushion, a cushion mount configured to mount the airbag cushion under a seat of a vehicle, and an inflator configured to inflate the airbag cushion. The airbag cushion is configured to project toward a floor of the vehicle and at least partially fill a space between a bottom surface of the seat and the floor of the vehicle when the airbag cushion is inflated to provide a reaction surface for a back surface of a leg of a passenger in the seat.

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.

A restraint system includes a restraint, an anchor coupled to the restraint and movable along an anchor guide, an anchor energy-absorbing (EA) device configured to control movement of the anchor along the anchor guide, and a controller that includes a processor configured to receive information indicative of an imminent event, receive information indicative of a recline angle being above a recline threshold, and send a command to enable the anchor to move along the anchor guide under control of the anchor EA device based on the information indicative of the imminent event and the recline angle being above the recline threshold.

An anti-submarining seat cushion for a vehicle includes a main body constructed of an anisotropic material. The anisotropic material includes a primary material including a primary stiffness and a plurality of inserts that are dispersed throughout the primary material. The plurality of inserts exert an axial compressive force in response to the main body of the anti-submarining seat cushion experiencing a submarining load, where the axial compressive force is exerted in a direction that opposes the submarining load to increase an overall stiffness of the main body in a direction that aligns with the submarining load.

A vehicle seat includes a pelvis movement suppression member, a moving mechanism, a control section and an energy-absorbing mechanism. The pelvis movement suppression member is disposed at a seat upper side of a seat front side of a seat cushion, extends in a seat width direction, and is movable in a seat front-rear direction relative to a frame of the seat cushion. The moving mechanism moves the pelvis movement suppression member from an initial position to a restraining position at a seat rear side relative to the initial position. When a collision is detected or predicted, the control section activates the moving mechanism and moves the pelvis movement suppression member to the restraining position.

An occupant protection device includes a seat having a seat portion and a backrest portion, a first restraining member configured to restrain a left shoulder of an occupant, a second restraining member configured to restrain a right shoulder of the occupant, a take-up unit that holds and takes up the first restraining member and the second restraining member, and a lifting unit, wherein the first restraining member and the second restraining member are fed out from a housing portion of the seat owing to being taken up by the take-up unit, and restrain the left and right shoulders, and wherein the lifting unit causes a front edge side of a seat face of the seat portion to rise when the take-up unit takes up the first restraining member and the second restraining member.

A vehicle seat that includes: an inflator that is disposed at a seat front end portion, inside a seat portion of a seat cushion, and that generates gas by operating; a first bag portion that is disposed inside the seat portion, that internally houses the inflator, and that, by being supplied with gas from the inflator, is inflated in a longitudinal direction, which is a seat front-rear direction; and a second bag portion that is disposed inside the seat portion on a seat rear side of the first bag portion and communicates with the first bag portion, that has a longitudinal direction extending in a seat width direction, and that has a length in the seat width direction which is longer than that of the first bag portion.

An anti-submarining seat structure includes a seat frame, upholstery, an anti-submarining device, a sensor and a controller. The upholstery overlays the seat frame at least partially forming a seat cushion portion with a cavity between the seat frame and a portion of the upholstery adjacent to a front area of the seat frame. The anti-submarining device is installed within the cavity and is configured to transition from an unactuated orientation to an actuated orientation. In the actuated orientation, the anti-submarining device forms a restraining structure proximate the front area of the seat cushion portion. The sensor is configured to detect rapid changes in acceleration and velocity of the vehicle body structure. The controller is connected to the anti-submarining device and the sensor and is configured to actuate the anti-submarining device in response to signals from the sensor indicating a rapid change in acceleration and velocity of the vehicle body structure.

A seat assembly includes a seat member having a support surface, wherein the support surface is disposed at an inclined angle from a rear portion to a front portion thereof. A seat cover covers the support surface. An airbag assembly is disposed below the seat cover at the front portion of the support surface at a thigh support region. The airbag is operable between inflated and deflated conditions, wherein the airbag assembly increases the inclined angle of the support surface when the airbag assembly is in the inflated condition.

In a vehicle seat frame, a connection member that connects left and right links together in a seat left-right direction is disposed below a rear portion of a cushion pan included in a seat cushion frame. A sloped surface sloped with a downward gradient toward a seat rear side is formed at a lower surface of the rear portion of the cushion pan. The sloped surface of the cushion pan slides in a seat rearward and diagonally downward direction relative to the connection member when the cushion pan deforms in a seat downward direction under load from the occupant during a head-on collision of the vehicle.
