Embodiment Construction

[0012] In the occupant restraint device of the present invention, in an emergency such as a vehicle collision, after the inflator performs a gas ejection operation, the gas is supplied from the inflator into the inner air bag, the inner air bag is inflated, and the air in the inflator Gas flows out from the outflow portion into the seat bag, thereby inflating the seat bag. The seat cushion is pushed up from the bottom by the inflated seat air bag, or is compressed and hardened by the upward pushing force, thereby preventing or restraining the occupant's waist from moving forward ("submersion" phenomenon).

[0013] In the present invention, the inner air bag is inflated earlier than the seat air bag by the high-pressure gas supplied from the inflator, and the seat air bag is inflated thereafter.

[0014] In the present invention, the lower part of the inner air bag is connected to the lower part of the seat cushion, and the upper part is connected to the upper part of the seat ...

Abstract

An occupant restraint device in which the amount of upward inflation of a seat bag is limited. The occupant restraint device (10) has the seat bag (12) extending in the direction of left-right width direction of a seat and inflatable to press a seat cushion from the underside; a retainer (11) placed on a seat pan (1); an inner bag (13) placed in the seat bag (12); and an inflator (14) for inflating the seat bag (12) and the inner bag (13). The inner bag (13) is connected at its lower part to the retainer (11) and at its upper part to the upper part of the seat bag (12).

Description

technical field [0001] The present invention relates to an occupant restraint device for restraining occupants on seats of vehicles such as automobiles during a collision, in particular to an occupant restraint for restraining the occupant's waist and preventing the occupant's body from moving forward and downward during a forward collision device. Background technique [0002] As a system for restraining the occupants of a car during a collision, in order to prevent the phenomenon of "submerging" from the underside of the belt in the event of a frontal collision even if the occupant is wearing a seat belt, JP-A-2004-338514 describes the following Occupant restraint device: An inflatable seat air bag (referred to as an air bag main body in the same gazette) is disposed between the seat cushion and the seat pan, and the seat cushion is pushed up by inflating the seat air bag during a vehicle collision The front part of the seat air bag, wherein an auxiliary air bag is arrang...
