Air-bag module mounting structure
View Patent ↗An air-bag module mounting structure where a fixing part 88 of a hub 80 of a steering wheel is fastened to a fastened part 24 of a horn plate 20 to which an air-bag module is fixed. A body cover 30 includes a positioning pin 31 protruding toward the hub 80 and a hook 38 protruding from a side surface 37 of the positioning pin 31 . The hub 80 includes an insertion hole 84 into which the positioning pin 31 is inserted and with which the hook 38 engages; and a stopper 87 that prevents the horn plate 20 from moving, because of a gap d 2 existing between the insertion hole 84 and the positioning pin 31 , when the fixing part 88 and the fastened part 24 are fastened together. The gap d 2 allows the positioning pin 31 to pass through the insertion hole 84 while the positioning pin 31 is bent due to a contact between the hook 38 and the insertion hole 84.
1. An air-bag module mounting structure, comprising:
a steering wheel including a hub disposed inside of an annular rim;
an air-bag module disposed in front of the hub;
a holding part to which the air-bag module is fixed; and
a cover part disposed at the back of the hub, a fixing part of the hub and a fixed part of the holding part being fastened together,
wherein the cover part includes a protruding part protruding toward the hub, a hook protruding from a side surface of the protruding part, and a cover-side connection part formed on a head of the protruding part;
wherein the holding part includes a holding-part-side connection part that is connected to the cover-side connection part; and
wherein the hub includes
an insertion hole into which the protruding part is inserted and with which the hook engages, and
a stopper that prevents the holding part from moving, because of a gap existing between the insertion hole and the protruding part, when the fixing part and the fixed part are fastened together, the gap allowing the protruding part to pass through the insertion hole while the protruding part is bent due to a contact between the hook and the insertion hole.
2. The air-bag module mounting structure as claimed in claim 1 , wherein the stopper is disposed on an opposite side of the gap from the protruding part.
3. The air-bag module mounting structure as claimed in claim 1 , wherein the stopper protrudes from the fixing part.
4. The air-bag module mounting structure as claimed in claim 1 , wherein the hub includes a second stopper that prevents the holding part from moving in a direction opposite to a direction in which the protruding part protrudes.
5. The air-bag module mounting structure as claimed in claim 4 , wherein the second stopper is disposed to face the holding-part-side connection part.
6. The air-bag module mounting structure as claimed in claim 5 , wherein a clearance is provided between the second stopper and the holding-part-side connection part.
