Garnish mounting structure

Abstract

To provide a garnish attachment structure which is superior in inflating and deploying performance of an airbag.SOLUTION: A garnish attachment structure 101 comprises: a garnish 20 provided on a cabin 5 side of an airbag 10; and a tether clip 30 for fastening the garnish 20 to a body panel 3. The garnish 20 includes: a body part 24 covering the airbag 10 from the cabin side; and an assembling seat 25 for assembling the body part 24 to the tether clip 30. A breakable fragile part W is provided on the assembling seat 25. When receiving a load produced at the time of inflation and deployment of the airbag 10, the garnish 20 forms a protrusion opening for the airbag 10 between the body part 24 and the body panel 3 in a state of being fastened to the body panel 3 by the tether clip 30, and then expands the protrusion opening more than before breakage by breaking the fragile part W of the assembling seat 25.SELECTED DRAWING: Figure 2

Claims

1. A garnish that is located on the passenger compartment side of the airbag, The tether clips used to secure the above garnish to the body panel, Equipped with, The above garnish comprises a main body that covers the airbag from the passenger compartment side, and an attachment seat for attaching the main body to the tether clip, and the attachment seat is provided with a breakable weak portion. The above garnish is configured such that, when subjected to the load generated when the airbag inflates and deploys, it forms a protruding opening for the airbag between the main body and the body panel while being secured to the body panel by the tether clip, and then the fragile portion of the mounting seat ruptures, thereby expanding the protruding opening beyond what it was before the rupture. The above-mentioned mounting base has a top plate portion having mounting holes and a wall portion that is erected from the main body portion and extends to the top plate portion, and the above-mentioned tether clip has a body mounting portion and a holding portion that is inserted into and held in the mounting holes of the top plate portion, The aforementioned vulnerable portion is provided in the wall portion, The tether clip's holding portion includes a retaining portion that engages with the top plate, an anchor portion, and an extendable arm portion that connects the retaining portion and the anchor portion in an extendable manner. The garnish mounting structure is configured such that, when subjected to the above load, the retaining portion comes out of the mounting hole in the top plate portion, the anchor portion locks into the top plate portion in place of the retaining portion, and subsequently, the weak portion of the mounting seat breaks while the telescopic arm portion is extending against its elastic holding force or after it has extended to approximately its maximum length.

2. A garnish provided on the side of the vehicle interior that is closer to the airbag, The tether clips used to secure the above garnish to the body panel, Equipped with, The above garnish comprises a main body that covers the airbag from the passenger compartment side, and an attachment seat for attaching the main body to the tether clip, and the attachment seat is provided with a breakable weak portion. The above garnish is configured such that, when subjected to the load generated when the airbag inflates and deploys, it forms a protruding opening for the airbag between the main body and the body panel while being secured to the body panel by the tether clip, and then the fragile portion of the mounting seat ruptures, thereby expanding the protruding opening beyond what it was before the rupture. The above-mentioned mounting base has a top plate portion having mounting holes and a wall portion that is erected from the main body portion and extends to the top plate portion, and the weak portion is provided in the wall portion. The tether clip has a body mounting portion, a retaining portion that is inserted into the assembly hole of the top plate portion and is locked to the top plate portion, and is configured to come out of the assembly hole when the load acting on the tether clip reaches a threshold, and an anchor portion that, after the retaining portion comes out of the assembly hole of the top plate portion, locks to the top plate portion in place of the retaining portion, thereby connecting the top plate portion to the body panel.
