Definitions

  • the present invention relates to a clip for attaching a pillar trim.
  • a vehicle such as an automobile has a roof member (for example, a roof panel) disposed above a side wall (for example, a door, a body side panel, etc.) of the vehicle main body and a pillar that supports the roof member. Since most of the pillars are made of metal (for example, steel plate material), the pillars are covered with pillar trims that form the inner wall of the passenger compartment from the inside of the vehicle.
  • the pillar trim is configured by combining an appropriate synthetic resin material, fiber material, and the like in the same manner as other trim materials.
  • the pillar trim covers the pillar and has a design function of making the vehicle interior wall a smooth surface shape and a function of protecting the occupant when the vehicle collides. For example, a front pillar is disposed at the front of the vehicle.
  • the front pillar is covered with a front pillar trim configured as an inner wall of the passenger compartment from the inside of the vehicle.
  • An airbag device generally called a curtain airbag is provided in a vehicle for protecting a passenger in the event of a vehicle collision.
  • the airbag device includes an airbag, and the airbag is folded and stored in the front pillar and the roof side rail.
  • the igniter ignition device
  • the airbag is inflated and deployed in a curtain shape along the side of the passenger compartment, and can protect the occupant during a collision.
  • the airbag stored in the front pillar is folded and stored inside the front pillar trim. The airbag pushes the rear end portion of the front pillar trim due to the inflation pressure of the airbag at the time of a vehicle collision, and develops along the side surface of the passenger compartment from a gap generated between the front pillar and the front pillar trim.
  • JP 2010-168044 A discloses a clip for attaching a pillar trim.
  • the clip includes an attachment body that attaches the pillar trim to the pillar, and a restriction body that regulates an amount by which the pillar trim is lifted from the pillar when the airbag is inflated.
  • the restricting body has a length that allows an amount of the pillar trim to be lifted.
  • the front end of the restricting body is provided with a locking portion that restricts the pillar trim from moving more than necessary for deployment of the airbag.
  • the pillar trim mounting clip is linear or bow-shaped. Therefore, when the airbag is deployed and the pillar trim is detached from the pillar, the pillar trim is lifted from the pillar at a stretch by the inflation pressure. As a result, the pillar trim instantaneously reaches the locking portion formed at the tip of the clip regulating body. For this reason, the impact associated with the inflation of the airbag concentrates on the locking part, and the locking part tends to break. Therefore, there is a concern that the clip is damaged and the pillar trim is dropped from the pillar. Or there is a concern that the pillar trim breaks and scatters.
  • a non-woven fabric or the like that absorbs the impact is wound around the clip locking portion.
  • a skin is stuck on the surface of the pillar trim, or a tape is stuck on the back surface of the pillar trim.
  • skin and tape increases the material cost.
  • the clip has a straight long shape, and is pushed into the pillar trim so that a part of the clip is bent.
  • the gap between the pillar and the pillar trim is narrow, the clip is difficult to bend, and the clip is difficult to attach.
  • the pillar trim mounting clip has a mounting body and a regulating body.
  • the attachment body attaches a pillar trim that covers the pillar from the inside of the vehicle to the pillar that supports the roof member of the vehicle body.
  • the regulating body regulates an amount by which the pillar trim moves away from the pillar when the airbag stored between the pillar and the pillar trim is inflated.
  • the restricting body has a movement guide part and a movement locking part.
  • the movement guide portion extends from the portion fitted in the mounting opening of the pillar trim of the mounting body and allows the pillar trim to move so as to form a gap between the pillar trim and the pillar necessary for the airbag to deploy. It has a predetermined length.
  • the movement locking part is provided at the tip of the movement guide part and is locked to the pillar trim to restrict the movement of the pillar trim.
  • the movement guide part is provided with an impact mitigation mechanism that obstructs the movement of the attachment opening and reduces the impact caused by the movement of the pillar trim when the attachment opening of the pillar trim moves along the movement guide part.
  • the restricting body is formed integrally with the mounting body. Therefore, the clip has two functions without increasing the number of parts. In one function, the clip attaches the front pillar trim to the front pillar. In another function, the clip restricts the movement of the front pillar trim when the airbag is inflated.
  • the movement guide part has an impact mitigation mechanism. Therefore, the pillar trim moves away from the pillar when the airbag is inflated. It moves along the movement guide part until the mounting opening of the pillar trim reaches the movement locking part. Movement of the mounting opening is hindered by an impact mitigation mechanism. Therefore, the impact generated when the airbag is inflated and the pillar trim moves is alleviated. Thereby, damage to the clip and the pillar due to the impact can be prevented.

Abstract

L'invention concerne une agrafe de montage pour garniture de montant (100) ayant un corps d'attache (110) et un corps de restriction (120). Le corps d'attache (110) permet de monter une garniture de montant (30) sur un montant (10), ledit montant supportant un élément de toiture d'une caisse de véhicule, et recouvrant le montant (10) depuis le côté intérieur du véhicule. Le corps de restriction (120) limite la distance d'éloignement de la garniture de montant (30) par rapport au montant (10) quand un coussin de sécurité gonflable (60) placé entre le montant (10) et la garniture de montant (30) est gonflé. Le corps de restriction (120) a une section de guidage de mouvement (122) et une section de verrouillage de mouvement (130). La section de guidage de mouvement (122) s'étend depuis la partie du corps d'attache (110) qui est adaptée sur une pièce d'ouverture d'attache (38) de la garniture de montant (30), et a une longueur prédéterminée qui permet à la garniture de montant (30) de se déplacer de manière à former un espace entre la garniture de montant (30) et le montant (10), ledit espace étant nécessaire pour le déploiement du coussin de sécurité gonflable (60). La section de verrouillage de mouvement (130) se trouve à l'extrémité de la section de guidage de mouvement (122) et est verrouillée au niveau de la garniture de montant (30) afin de limiter le mouvement de la garniture de montant (30). Un mécanisme de réduction d'impact (124) se trouve dans la section de guidage de mouvement (122), ledit mécanisme de réduction d'impact permettant d'atténuer un impact causé par le mouvement de la garniture de montant (30) en faisant obstacle au mouvement de la pièce d'ouverture d'attache (38) quand la pièce d'ouverture d'attache (38) de la garniture de montant (30) se déplace le long de la section de guidage de mouvement (122).
