JP2003104156A - Pillar garnish structure - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve the cost problem arising from the use of materials capable of withstanding extensive deformation and damage for a pillar garnish in a vehicle provided with an airbag to bridge the pillar and the roof side like a curtain upon deployment and from the need of a surface material to cover the surface. SOLUTION: In this inexpensive design, the pillar garnish of the on-vehicle head protecting airbag comprises a bracket section and a face section, and the bracket section and the face section both open up upon deployment of the airbag, this easing the stress to be generated by airbag expansion.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a pillar garnish in a vehicle equipped with an airbag provided with an airbag bag extending in a curtain shape over a pillar and a roof side. Things. 2. Description of the Related Art Conventionally, a pillar garnish structure of a vehicle equipped with an airbag device having a curtain and an airbag bag extending over a roof and a roof side includes a pillar inner panel mounting portion of the pillar garnish and a face. When the airbag is deployed, the airbag deployment side of the pillar garnish mounting portion is locally deformed and partially opened to deploy the airbag. [0003] However, in the above structure, the deployment side of the airbag is locally deformed and opened (FIG. 2) at the pillar garnish mounting section in the pillar garnish cross section. Therefore, the pillar garnish is easily broken at the portion where the deformation stress is concentrated. [0004] For this reason, as a material for the pillar garnish, an expensive material having the property of withstanding large deformation and being hardly damaged has to be used. [0005] In addition, a structure is required to cover the surface of the pillar garnish with the epidermis so that the human body is not damaged by the broken surface even if it is damaged, and there has been a problem that the cost is further increased. According to the present invention, a pillar garnish in a vehicle equipped with a head protection airbag device is configured to relieve stress when an airbag is deployed, and particularly expensive materials and skins are used. The main feature is that it is obtained without using. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The purpose of obtaining a pillar garnish in a vehicle equipped with a head protection airbag device without using particularly expensive materials or skins is to form the pillar garnish with a mounting portion and a face portion. In addition, the fastening between the bracket portion and the face portion is fixed by a clip structure at least on the deployment side of the airbag bag body, so that the clip structure comes off when the airbag bag body is deployed, and This is achieved by increasing the cross-sectional circumferential length of a portion that is deformed at the time of opening by opening the face portion. FIG. 3 shows a first embodiment of the present invention. FIG. 4 shows a cross-sectional shape of the pillar garnish when the airbag according to the first embodiment is deployed. The pillar garnish (1) is divided into a face portion (1B) and a bracket portion (1C). When the airbag bag (4) is deployed, the clip portion (1E) comes off. In addition, it suppresses a large deformation that is suitable for the area at the time of opening. [0010] The fastening portion (1) between the bracket portion and the face portion
For fixing D), it is preferable to fit a claw of the face part into a fixing hole of the bracket part, but it may be fixed by heat welding or a clip. FIG. 5 shows a second embodiment, in which the opening of the bracket portion and the face portion when the airbag is deployed is fixed with a Velcro (registered trademark). As described above, in the structure of the present invention, an inexpensive material having lower brittleness than the conventional one can be used, the surface covering the surface can be eliminated, and the head protection airbag device can be mounted. There is an advantage that pillar garnish in a vehicle can be reduced in cost. In addition, since the pillar opening surface is easily opened, the workability during maintenance of the head protection airbag device is improved, and it is easy to adapt to various specifications by changing only the face portion.
