[0029] The following will use Figure 1 to Figure 6 The vehicle occupant restraint system 10 will be described in relation to the first embodiment. It should be noted that arrow FR, arrow UP, and arrow OUT appearing in the drawings indicate the forward direction (traveling direction), upward direction, and outward direction in the width direction of the vehicle, respectively. The description below uses only the front / rear, right / left, and up / down directions, and unless otherwise specified, these will be understood to mean front / rear in the vehicle front-rear direction, vehicle left-right direction (vehicle width direction) Right / Left, and Up / Down in the vertical direction of the vehicle.

[0030] Such as figure 1 and figure 2 As shown, the vehicle occupant restraint system 10 related to the present embodiment includes a side airbag device 20, an inside airbag device 22, and a side support portion 14A provided in the vehicle width direction outer side of the seat back 14 of...

[0080] exist Figure 9 in, through the Figure 5 The corresponding sectional view shows a partial configuration of a vehicle seat to which the vehicle occupant restraint system 80 related to the second embodiment of the present disclosure has been applied. also, Figure 10 A plan view showing the side airbag 40 and the inner airbag 56 in a flattened deployed state related to the second embodiment. In the second embodiment, the side airbag 40 and the inner airbag 56 are formed in a single bag shape using a common base fabric. That is, in the second embodiment, the side airbag 40 and the inner airbag 56 are constituted by a single bag 82 .

[0081] Such as Figure 10 As shown, the pouch 82 is formed by overlapping two generally L-cut base fabrics and seaming them at a peripheral seam 84 ( Figure 9 Not shown in ), the outer peripheral edge portions are sewn together to form a bag shape. A single inflator 86 is housed within the bag 82 . The inflator 86 is a two-stage infl...

Abstract

A vehicle occupant restraint system is disclosed. The vehicle occupant restraint system includes: a plurality of occupant restraint devices arranged in a side support portion of a seat back of a vehicle seat and configured to restrain an occupant when activated; and a control device configured to cause Activation timings of the plurality of occupant restraint devices are staggered such that loads acting simultaneously on the occupant from the plurality of occupant restraint devices are equal to or smaller than a maximum value of loads acting on the occupant individually from the plurality of occupant restraint devices.

Description

technical field [0001] The present disclosure relates to a vehicle occupant restraint system provided at a side support portion of a seat back of a vehicle seat. Background technique [0002] Japanese Patent Application (JP-A) Publication No. 2008-087631 discloses a side airbag device in which an auxiliary inflator (inner airbag) is provided in a side support portion of a seat back at a lower position than the main inflator ( Side airbags) are located closer to the inside of the vehicle. When the vehicle is collided sideways, the inner airbag is inflated and deployed earlier than the side airbag, and pushes the upper body of the occupant sitting in the vehicle seat toward the vehicle inner side (opposite side of the collision position) in the vehicle obliquely forward direction. Thereby, a wide space for inflation and deployment of the side airbag can be secured, thereby performing inflation and deployment quickly and reliably. [0003] However, in the side airbag device h...
