An attachment member allowing a connected state between the attachment member and a guide member to be more easily checked is provided. The attachment member for attaching a stay cloth, which guides a deployment direction of an airbag module, to a seat back frame has a holding portion which includes a holding space for housing an attachment portion of the stay cloth. The holding portion is inserted into an attachment hole to be fitted into the attachment hole that is formed in the seat back frame. A through-hole which allows the attachment portion of the stay cloth in the holding space to be exposed in a penetrating direction of the attachment hole is formed in the holding portion.

A side air bag device is described which is disposed in a space between a vehicle body and a back seat and for which rigidity of attachment to a vehicle body member is improved. The side air bag device provided between a vehicle body and a back seat includes: a base member including a base storage configured to store an air bag and an inflator and a base attachment portion attached to the vehicle body; and a retainer member configured to hold the base storage from a vehicle back side. The retainer member extends from a portion holding the base storage while being bent along the shape of the vehicle body. The retainer member is attached to the vehicle body together with the base attachment portion while being overlapped with the base attachment portion.

The present disclosure relates to a gas generator for airbag(s) including: at least one pyrotechnic charge and a system for igniting/activating said charge triggered during a predetermined condition.

A configuration is adopted such that the shape of a peripheral wall portion of a shell-shaped seat back skeleton can be freely set without being restricted by the presence of brackets, the incidence of warping of the seat back skeleton when a vehicle is involved in a rear-end or head-on collision is reduced, and the seat back skeleton does not lose strength even when brackets are affixed to the seat back skeleton. A seat cushion skeleton 8 and the seat back skeleton 9 are coupled by coupling means 19a, 19b, and the seat back skeleton 9 has a main body 14 facing the back of a seated passenger, and a peripheral wall part 15 provided to the peripheral edge of the main body 14. The main body 14 and the peripheral edge part 15 are formed into an integrated shell shape using a synthetic resin. The coupling means 19a, 19b have first brackets 21a, 21b that are joined to the seat back skeleton 9, the first brackets 21a, 21b being affixed by bonding to the main body 14 of the seat back skeleton 9.

The present invention provides a seat frame inflator including a seat frame housing portion formed of a seat frame having a hollow structure and forming an outer shell of a pressurized gas chamber, and a partition member disposed on a hollow side of the seat frame and configured to isolate the pressurized gas chamber and a gas chamber outer region from each other. The partition member is provided with a communication hole, and a closing member configured to close the communication hole. The seat frame inflator includes an opening member disposed on the hollow side of the seat frame, and configured to open the pressurized gas chamber, and a gas discharge port formed in the seat frame to face the gas chamber outer region and configured to discharge, from the gas chamber outer region to the outside, the pressurized gas flowing from the pressurized gas chamber.
