Attaching structure for air belt inflator
View Patent ↗An inflator attaching structure is capable of firmly attaching an inflator to a seat member or the like. An inflator attaching structure includes an attaching clamp that is composed of a main plate connected to a seat frame, and a sub-plate attached to the main plate, and an inflator is sandwiched between the main plate and the sub-plate. When attaching the inflator to the attaching clamp, a hook portion of the sub-plate is hooked on a hook-portion hooking opening of the main plate, and thereafter the fastening portion and the base piece portion are fastened by a bolt upon situating the fastening portion of the sub-plate in parallel with the base piece portion of the main plate in a manner so as to sandwich the inflator between the main plate and the sub-plate.
1. A structure for attaching an inflator, for expanding a bag of an expandable air belt, to a seat member of a vehicle body, wherein the seat member includes a lap anchor side and a buckle side, and wherein the structure comprises an attaching member that includes:
a main plate attached to the lap anchor side of the seat member;
a sub-plate attached to the main plate, wherein the inflator is sandwiched between the main plate and the sub-plate; and
wherein a base end side of a lap portion of the expandable belt is connected to the main plate; and
wherein the main plate is attached to the seat member in a manner so as to be rotatable in a front-and-back direction of a seat.
2. The structure according to claim 1 , wherein a hook portion is provided at either one of the main plate or the sub-plate, and a hook opening to be caught by the hook portion is provided at the other plate, and wherein the hook portion catches the hook opening, and portions of the main plate and the sub-plate that are at a side opposite to the hook portion and hook opening across the inflator are fastened by a fastening member.
3. The structure according to claim 1 , wherein a plate thickness of the sub-plate is configured to be smaller than a plate thickness of the main plate.
4. The structure according to claim 1 , wherein a convex positioning portion is provided in either one of an outer peripheral surface of the inflator or an inflator-opposed surface of the attaching member, and an engaging portion for engaging the convex portion is provided in the other surface.
